73-559: The Jaguar XJ (X351) is a saloon car built by British manufacturer Jaguar Cars , later known as Jaguar Land Rover , from 2010 to 2019. It is the fourth-generation of the Jaguar XJ model. Referred to internally within Jaguar as the X351, it was announced in 2009 before going on sale in 2010, and combines revised styling with underpinnings of the previous Jaguar X350 generation. The model

146-448: A CO 2 emission rating of 184  g/km . The car has been used by British prime ministers . Dating back to the Jaguar XJ (Series III) , various versions of the XJ were used by Margaret Thatcher , John Major , Tony Blair , and Gordon Brown . On 11 May 2010, David Cameron took delivery of the dark grey car No. 10 Jaguar XJ Sentinel as his prime ministerial car . In 2011, Cameron took

219-406: A Lane Keeping Assist function on the new E-class . This system warns the driver (with a steering-wheel vibration) if it appears the vehicle is beginning to leave its lane. Another feature will automatically deactivate and reactivate if it ascertains the driver is intentionally leaving his lane (for instance, aggressively cornering). A newer version will use the braking system to assist in maintaining

292-401: A car of this configuration is called a saloon ( / s ə ˈ l u n / ). Hatchback sedans are known simply as hatchbacks (not hatchback saloons ); long-wheelbase luxury saloons with a division between the driver and passengers are limousines . In Australia and New Zealand , sedan is now predominantly used; they were previously simply cars. In the 21st century, saloon remains in

365-448: A choice of veneers, and contrasting stitching on the seats. The XJR was initially unveiled at 2013 New York Auto Show , followed by the 2013 Goodwood Festival of Speed . The US model went on sale as 2014 model year vehicle. All models include ZF 8HP eight-speed automatic transmission. Changes include optional Intelligent All-Wheel Drive System for 3.0-litre V6 petrol engine models, addition of long-wheelbase models, power output of

438-459: A curve with a radius lower than 250 meters. Lane departure warning systems also face many legal limitations regarding autonomous driving. As stated previously, this system requires constant driver input. Vehicles with this technology are limited to assisting the driver, not driving the vehicle. Lane departure warning systems biggest limitation is that it is not in complete control of the vehicle. The system does not take into account other vehicles on

511-510: A deactivation switch on the dashboard; it works by using an optical sensor on both sides of the car. Audi A7 introduces Audi active lane assist. Mobileye developed a system that detected lane markings , and identified when a vehicle departed from its driving lane without the use of the turn signal. Mercedes began Distronic Plus with Steering Assist and Stop&Go Pilot on the redesigned S-class in 2013. Tesla Model S comes with advanced lane assistance systems with their 2014 release. It

584-679: A four-door station wagon from 1958 until 1960 in the Rambler and Ambassador series. In 1973, the US government passed Federal Motor Vehicle Safety Standard 216 creating a standard roof strength test to measure the integrity of roof structure in motor vehicles to come into effect some years later. Hardtop sedan body style production ended with the 1978 Chrysler Newport . Roofs were covered with vinyl, and B-pillars were minimized by styling methods like matt black finishes. Stylists and engineers soon developed more subtle solutions. A close-coupled sedan

657-473: A mobile phone. An Insurance Institute for Highway Safety raised concern that drivers may be less vigilant when relying on automated safety systems or become distracted by dashboard displays that monitor how the systems are performing. Two separate studies found that lane-keeping systems and blind spot monitoring systems had lower crash rates than the same vehicles without the systems. Police crash data from 25 states between 2009 and 2015 for vehicle models where

730-453: A proportion of the earlier floor pan. The biggest change is reversion to steel coil springs for the front suspension, retaining air suspension for the rear only. Continuously variable damping is electronically controlled as before but with driver selectable modes. The aluminium alloy uni-body makes the XJ L among the lightest of the full-size executive saloons despite its exterior proportions, weighing in at 1,874 kg (4,131 lb), which

803-574: A railroad train's club carriage (e.g.,, the lounge or parlour carriage). From the 1910s to the 1950s, several United States manufacturers have named models either Sedanet or Sedanette. The term originated as a smaller version of the sedan; however, it has also been used for convertibles and fastback coupes. Models that have been called Sedanet or Sedanette include the 1917 Dort Sedanet, King , 1919 Lexington , 1930s Cadillac Fleetwood Sedanette, 1949 Cadillac Series 62 Sedanette, 1942-1951 Buick Super Sedanet , and 1956 Studebaker . Sedans, as

876-644: A roof. A one-off instance of similar coachwork is also known in a 1900 De Dion-Bouton Type D. A sedan is typically considered to be a fixed-roof car with at least four seats. Based on this definition, the earliest sedan was the 1911 Speedwell , which was manufactured in the United States. In American English , Latin American Spanish , and Brazilian Portuguese , the term sedan is used (accented as sedán in Spanish). In British English ,

949-422: A sedan can have four or two doors. Although the sloping rear roofline defined the coupe, the design element has become common on many body styles with manufacturers increasingly "cross-pollinating" the style so that terms such as sedan and coupé have been loosely interpreted as "'four-door coupes' - an inherent contradiction in terms." When a manufacturer produces two-door sedan and four-door sedan versions of

1022-414: A specific category of automobiles, have had serious social consequences shaped by their design and use. Their compact and fuel-efficient nature has made them a preferred choice for urban and suburban settings, promoting individual mobility. However, this accessibility has contributed to increased urban sprawl and car dependency. Sedans, like other private vehicles, encourage dispersed living patterns, reducing

1095-551: A television transmission. Standard equipment levels on the United States-spec XJ L with the base engine includes a panoramic dual-pane moonroof, lane-departure warning , navigation, quad-zone climate control, and power sunshades, which is considered to be generous at this price point compared to other flagship executive saloons. The diesel engine version had a fuel economy of better than 40 miles per imperial gallon (7.1 L/100 km; 33 mpg ‑US ) and

1168-790: A vehicle back into the lane if it starts to leave or proactively keep the vehicle in the center of the lane. Vehicle companies often use the term "lane keep(ing) assist" to refer to both reactive lane keep assist (LKA) and proactive lane centering assist (LCA) but the terms are beginning to be differentiated. Tesla uses the most advanced lane assist system (kind of LKA) combined with their adaptive cruise control system marketed together as ' Autopilot '. In 2020, UNECE released an automated lane keeping system (ALKS) regulation which include features such as lane-keeping and adaptative speed for specific roads up to 60 km/h. Tesla includes features like lane-keeping assist and also automatic lane changing without driver input. A similar technology to lane assist

1241-435: A vehicle which drifts beyond a solid lane marking. One of the main causes of single vehicle crashes and frontal crashes is lane departure. The goal of the lateral support systems (LSS) is to help to avoid such crashes. Without those LSS systems, lane departure can be unintentional; the car drifts towards and across the edge of the lane. The car then reach a potentially dangerous situation. This system does not work when

1314-407: Is 111 kg (245 lb) lighter than the mid-size/executive BMW 550i . Driver information and entertainment is provided by a Bowers & Wilkins 1,200-watt, 20-speaker Dolby 7.1 surround-sound system, along with a bi-directional touch screen display on which the driver can only see the vehicle functions and satellite navigation data; a front passenger can simultaneously view a DVD movie or

1387-587: Is a Stretch-Limousine . In the United States, two-door sedan models were marketed as Tudor in the Ford Model A (1927–1931) series. Automakers use different terms to differentiate their products and for Ford's sedan body styles "the tudor (2-door) and fordor (4-door) were marketing terms designed to stick in the minds of the public." Ford continued to use the Tudor name for 5-window coupes, 2-door convertibles, and roadsters since all had two doors. The Tudor name

1460-534: Is a passenger car in a three-box configuration with separate compartments for an engine, passengers, and cargo. The first recorded use of sedan in reference to an automobile body occurred in 1912. The name derives from the 17th-century litter known as a sedan chair, a one-person enclosed box with windows and carried by porters. Variations of the sedan style include the close-coupled sedan, club sedan, convertible sedan, fastback sedan, hardtop sedan, notchback sedan, and sedanet. A sedan ( / s ɪ ˈ d æ n / )

1533-457: Is a body style produced in the United States during the 1920s and 1930s. Their two-box boxy styling made these sedans more like crossover vehicles than traditional three-box sedans. Like other close-coupled body styles, the rear seats are farther forward than a regular sedan. This reduced the length of the body; close-coupled sedans, also known as town sedans, were the shortest of the sedan models offered. Models of close-coupled sedans include

1606-423: Is a car with a closed body (i.e., a fixed metal roof) with the engine, passengers, and cargo in separate compartments. This broad definition does not differentiate sedans from various other car body styles. Still, in practice, the typical characteristics of sedans are: It is sometimes suggested that sedans must have four doors (to provide a simple distinction between sedans and two-door coupés ); others state that

1679-538: Is a special model developed for the Hong Kong market. Based on the XJ L Portfolio with a 5.0-litre V8 engine, it includes the XJ rear seat comfort pack and gloss oak interior veneer as standard equipment. The XJ Ultimate is a special model introduced in 2011. Available only in the long wheelbase configuration, the car was developed by the Jaguar Land Rover's specialist Engineered To Order (ETO) division and

1752-547: Is mandatory for new cars and vans in the European Union as of 2022 under the name Emergency Lane Keeping System. Lane departure warning systems and lane keeping systems rely on visible lane markings. They typically cannot decipher faded, missing, or incorrect lane markings. Markings covered in snow or old lane markings left visible can hinder the ability of the system. UNECE regulation 130 does not require LDWS of heavy vehicles to work under 60 km/h or to work in

1825-437: Is used to do autopark feature as well. Requires driver control while vehicle is in use, but adjusts steering if vehicle detects itself drifting out of lane ((LKA) refers to reactive "lane keep(ing) assist" and (LCA) refers to proactive lane centering): List shows up to 2015 model year. This feature has become more widespread since then, as seen below. Allows unassisted driving under limited conditions Lane keeping assist

1898-684: The Chrysler Imperial , Duesenberg Model A , and Packard 745 A two-door sedan for four or five passengers but with less room for passengers than a standard sedan. A Coach body has no external trunk for luggage. Haajanen says it can be difficult to tell the difference between a Club and a Brougham and a Coach body, as if manufacturers were more concerned with marketing their product than adhering to strict body style definitions. Close-coupled saloons originated as four-door thoroughbred sporting horse-drawn carriages with little room for rear passengers' feet. In automotive use, manufacturers in

1971-533: The Infiniti FX and (in 2005) the M vehicles. In this system, a camera (mounted in the overhead console above the mirror) monitors the lane markings on a roadway. A warning tone is triggered to alert the driver when the vehicle begins to drift over the markings. Also in 2004, Toyota added a lane keeping assist feature to the Crown Majesta which can apply a small counter-steering force to aid in keeping

2044-498: The J -gate gear selector. The XJ has an electronically limited top speed of 250 km/h (155 mph); the limiter has been raised to 280 km/h (174 mph) for the XJR model. An eight speed automatic transmission was introduced from 2013 onwards. The XJ features a lightweight aluminium floorpan and body (with 50% recycled material content) based on the X350 chassis and retaining

2117-473: The electric power steering or EPS) steer the vehicle to hold its lane. It also applies counter-steering torque to help ensure the driver does not over-correct or "saw" the steering wheel while attempting to return the vehicle to its proper lane. If the radar cruise control system is engaged, the Lane Keep function works to help reduce the driver's steering-input burden by providing steering torque; however,

2190-614: The 1630s. Etymologists suggest the name of the chair very probably came through varieties of Italian from the Latin sedere , or the Proto-Indo-European root " sed- " meaning "to sit." The first recorded use of sedan for an automobile body occurred in 1912 when the Studebaker Four and Studebaker Six models were marketed as sedans. There were fully enclosed automobile bodies before 1912. Long before that time,

2263-526: The United Kingdom used the term to develop the chummy body, where passengers were forced to be friendly because they were tightly packed. They provided weather protection for extra passengers in what would otherwise be a two-seater car. Two-door versions would be described in the United States and France as coach bodies. A postwar example is the Rover 3 Litre Coupé . Produced in the United States from

Jaguar XJ (X351) - Misplaced Pages Continue

2336-464: The United States from the early 1950s into the 1970s provided at least a 2-door hardtop model in their range and a 4-door hardtop. The lack of side bracing demanded a strong, heavy chassis frame to combat unavoidable flexing. The pillarless design was also available in four-door models using unibody construction. For example, Chrysler moved to unibody designs for most of its models in 1960 and American Motors Corporation offered four-door sedans, as well

2409-758: The XJR is a high-performance variant of the XJ. Available in standard and long wheelbase configurations, it includes a 5.0-litre supercharged V8 engine rated at 550 PS (405 kW; 542 hp) and 680 N⋅m (502 lb⋅ft), an increased top speed to 280 km/h (174 mph), eight-speed automatic transmission with a bespoke tuning for the XJR, a new front splitter and aerodynamic sill section combined with an additional rear spoiler and unique R bonnet louvres, Electronic Active Differential and Dynamic Stability Control systems calibrated to enhance handling characteristics, new 20-inch Farallon forged alloy wheels with bespoke Pirelli low-profile tyres, semi-aniline leather,

2482-476: The XJR model increased to 550 PS (405 kW), Intelligent Stop/Start system for all engines and increased headroom for long-wheelbase models (except US model). The XJ received a facelift for MY2016. Changes include LED front and rear lights, rear J-Blade lights, a new grille, and a new InControl Touch Pro infotainment system, new driver assistance technology and a new audio system. Models 2017-2019 received an upgraded 10" infotainment LCD, up from 7" LCD that

2555-840: The car arriving in dealer showrooms in May 2010. Production was initially carried out only at the Castle Bromwich Assembly plant in Birmingham , England. From 2014, assembly from complete knockdown kits , or CKD, of the XJ commenced at Jaguar Land Rover's facility in Pune , India. The XJ was designed at Jaguar Land Rover's Whitley plant in Coventry by a team led by design director Ian Callum . Design work began in 2005, with final design approval taking place in November 2006 and

2628-583: The car called the XJ Sentinel was introduced. This is an armoured version of Long Wheelbase XJ with B7-level ballistic protection as well as providing protection against 15 kg TNT or equivalent explosive. It has the 5.0 L supercharged V8 engine shared with the XJ Supersport having a power output of 510 PS (375 kW) and 19-inch wheels with Dunlop Self Supporting Technology run-flat tyres . Unlike other full-size flagship executive cars,

2701-502: The combination of these features creates a semi-autonomous vehicle , most require the driver to remain in control of the vehicle while it is in use. This is because of the limitations associated with the lane-keeping feature. The lane keeping assist system is being achieved in modern vehicle systems using image processing techniques called Hough transform and Canny edge detection techniques. These advanced image processing techniques derive lane data from forward facing cameras attached to

2774-542: The delivery of another XJ Sentinel featuring bomb proof doors, bullet proof glass , and armoured plating beneath the floor of the car, respectively replacing the previous XJ Sentinel. The car was used for transporting Theresa May , and was also used by Boris Johnson . Under Johnson, the XJ was replaced for the first time since 1979 by the Range Rover Abio Sentinel as the prime ministerial car in 2019. New options include: The XJ V8 Portfolio Prestige

2847-482: The density of communities and limiting opportunities for local social interactions. This can lead to a decline in neighborhood growth and an increase in reliance on cars for even short trips, increasing environmental and health concerns through CO2 and Greenhouse Gas emissions and reduced physical activity . Furthermore, while sedans are a practical solution for families and individuals, their role in encouraging road-centric urban planning has been criticized for reducing

2920-404: The design being frozen in the first half of 2008. The new design is a complete departure from any earlier XJ model; mechanically, the car is a development of its predecessor. In addition to the standard version with a 3,035 mm (119.5 in) wheelbase, a long-wheelbase version was available with a 3,160 mm (124 in) wheelbase. At the 2010 Moscow Motor Show, a high security version of

2993-648: The downward-looking infrared sensors in the Citroën. Also in 2007, Infiniti offered a newer version of its 2004 system, which it called the Lane Departure Prevention (LDP) system. This feature utilizes the vehicle stability control system to help assist the driver maintain lane position by applying gentle brake pressure on the appropriate wheels. General Motors introduced Lane Departure Warning on its 2008 model-year Cadillac STS , DTS , and Buick Lucerne models. The General Motors system warns

Jaguar XJ (X351) - Misplaced Pages Continue

3066-589: The driver must remain active or the system will deactivate. In 2007, Audi began offering its Audi lane assist feature for the first time on the Q7 . This system, unlike the Japanese "assist" systems, will not intervene in actual driving; rather, it will vibrate the steering wheel if the vehicle appears to be exiting its lane. The LDW System in Audi is based on a forward-looking video-camera in its visible range, instead of

3139-418: The driver of an unintended lane change. This happens during speed limit non-compliance as well. Fiat is launching its lane keep assist feature based on TRW's lane keeping assist system (also known as the haptic lane feedback system). This system integrates the lane-detection camera with TRW's electric power-steering system; when an unintended lane departure is detected (the turn signal is not engaged to indicate

3212-420: The driver with an audible tone and a warning indicator on the dashboard. BMW also introduced Lane Departure Warning on the 5 Series (E60) and 6 Series , using a vibrating steering wheel to warn the driver of unintended departures. In late 2013 BMW updated the system with Traffic Jam Assistant appearing first on the redesigned BMW X5 , this system works below 25 miles per hour (40 km/h). Volvo introduced

3285-690: The driver's desire to change lanes), the electric power-steering system will introduce a gentle torque that will help guide the driver back toward the center of the lane. Introduced on the Lancia Delta in 2008, this system earned the Italian Automotive Technical Association's Best Automotive Innovation of the Year Award for 2008. Peugeot introduced the same system as Citroën in its new 308 . Lane departure warning systems combine prevention with risk reports in

3358-453: The edge of the lane is not marked by a line. A lane detection system used behind the lane departure warning system uses the principle of Hough transform and Canny edge detector to detect lane lines from realtime camera images fed from the front-end camera of the automobile. A basic flowchart of how a lane detection algorithm works to help lane departure warning is shown in the figures. Lane warning/keeping systems are based on: In Europe,

3431-445: The front of the vehicle. Real-time image processing using powerful computers like Nvidia 's Drive PX1 are being used by many vehicle OEMs to achieve fully autonomous vehicles in which lane detection algorithm plays a key part. Advanced lane detection algorithms are also being developed using deep learning and neural network techniques. Nvidia has achieved high accuracy in developing self-driving features including lane keeping using

3504-455: The lane departure warning system and the driver alert control on its 2008 model-year S80 , the V70 , and XC70 executive cars . Volvo's lane departure warning system uses a camera to track road markings and sound an alarm when drivers depart their lane without signaling. The systems used by BMW, Volvo, and General Motors are based on core technology from Mobileye . Mercedes-Benz began offering

3577-515: The lane departure warning system should be compatible with a visible lane marking identification standard such as commission regulation EU-351/2012. The concept and a working model of this technology was invented and fitted to a Rover SD1 in England by British inventor Nick Parish in 1988. Patent application No 8911571.1 was made in 1989. The first production lane departure warning system in Europe

3650-407: The long-established names of particular motor races. In other languages, sedans are known as berline ( French ), berlina ( European Spanish , European Portuguese , Romanian , and Italian ), though they may include hatchbacks. These names, like the sedan, all come from forms of passenger transport used before the advent of automobiles. In German , a sedan is called Limousine and a limousine

3723-500: The long-wheelbase variant was designed first and was expected to make up 67 percent of sales in the US market. The engine used by the X351 are enlarged and upgraded versions of the previously used V8 petrol and V6 diesel engines. All 2010 models of the Jaguar XJ include standard six-speed automatic transmission with Jaguar Sequential Shift carried over from the X350, the main change being steering wheel shift paddles rather than

3796-436: The mid-1920s to the mid-1950s, the name club sedan was used for highly appointed models using the sedan chassis. Some people describe a club sedan as a two-door vehicle with a body style otherwise identical to the sedan models in the range. Others describe a club sedan as having either two or four doors and a shorter roof and therefore less interior space than the other sedan models in the range. Club sedan originates from

3869-440: The neural network based training mechanism in which they use a front facing camera in a car and run it through a route and then uses the steering input and camera images of the road fed into the neural network and make it 'learn'. The neural network then will be able to change the steering angle based on the lane change on the road and keep the car in the middle of the lane. A lane keeping assist mechanism can either reactively turn

3942-509: The road ahead in a 40-degree radius, picking up the dotted white lines used to divide lane boundaries on the highway. The computer recognizes that the driver is "locked into" a particular lane, monitors how sharp a curve is, and uses factors such as yaw and vehicle speed to calculate the steering input required. In 2004, the first passenger-vehicle system available in North America was jointly developed by Iteris and Valeo for Nissan on

4015-522: The road. In a September 2022 retrospective, James Howe wrote: "Fans of the XJ may regard the X351 as too far removed from the familiar flowing lines of its seven predecessors, but even 12 years after it was launched at the Saatchi Gallery in London, and two years since production ceased, it still looks modern and unmistakably Jaguar." Saloon car A sedan or saloon ( British English )

4088-521: The same fully enclosed but horse-drawn carriages were known as a brougham in the United Kingdom, berline in France, and berlina in Italy; the latter two have become the terms for sedans in these countries. It is sometimes stated that the 1899 Renault Voiturette Type B (a 2-seat car with an extra external seat for a footman/mechanic) was the first sedan, since it is the first known car to be produced with

4161-463: The same model range. Several sedans have a fastback profile but a hatchback-style tailgate is hinged at the roof. Examples include the Peugeot 309 , Škoda Octavia , Hyundai Elantra XD , Chevrolet Malibu Maxx , BMW 4 Series Grand Coupe , Audi A5 Sportback , and Tesla Model S . The names hatchback and sedan are often used to differentiate between body styles of the same model. To avoid confusion,

4234-536: The same model, the shape and position of the greenhouse on both versions may be identical, with only the B-pillar positioned further back to accommodate the longer doors on the two-door versions. A sedan chair, a sophisticated litter , is an enclosed box with windows used to transport one seated person. Porters at the front and rear carry the chair with horizontal poles. Litters date back to long before ancient Egypt, India, and China. Sedan chairs were developed in

4307-578: The side of the vehicle drifting out of the lane. No warnings are generated if, before crossing the lane, an active turn signal is given by the driver. Nissan Motors began offering a lane-keeping support system on the Cima 450XV Limited (F500) sold in Japan. Toyota introduced its lane monitoring system on models such as the Caldina and Alphard sold in Japan; this system warns the driver if it appears

4380-518: The systems were sold as optional reduced rates of single-vehicle, sideswipe, and head-on crashes by 11 percent, and injuries in such crashes by 21 percent. The sample size was not large enough to control for demographic and other variables. Lane keeping assist (LKA) is a feature that, in addition to the lane departure warning system, automatically takes steps to ensure the vehicle stays in its lane. Some vehicles combine adaptive cruise control with lane keeping systems to provide additional safety. While

4453-472: The term hatchback sedan is not often used. There have been many sedans with a fastback style. Hardtop sedans were a popular body style in the United States from the 1950s to the 1970s. Hardtops are manufactured without a B-pillar leaving uninterrupted open space or, when closed, glass along the side of the vehicle. The top was intended to look like a convertible's top. However, it was fixed and made of hard material that did not fold. All manufacturers in

4526-424: The transportation industry. Viewnyx applies video-based technology to assist fleets in lowering their driving liability costs. By providing safety managers with driver- and fleet-risk assessment reports and tools, it facilitates proactive coaching and training to eliminate high-risk behaviors. The Lookout Solution is used by North American fleets, and there is research on implementing a lane departure warning system via

4599-561: The vehicle in its lane. Citroën became the first in Europe to offer LDWS on its 2005 C4 and C5 models, and its C6 . This system uses infrared sensors to monitor lane markings on the road surface, and a vibration mechanism in the seat alerts the driver of deviations. Lexus introduced a multi-mode lane keeping assist system on the LS 460 , which utilizes stereo cameras and more sophisticated object- and pattern-recognition processors. This system can issue an audiovisual warning and also (using

4672-457: The vehicle is beginning to drift out of its lane. Honda launched its Lane Keep Assist System (LKAS) on the Inspire . It provides up to 80% of steering torque to keep the car in its lane on the highway. It is also designed to make highway driving less cumbersome, by minimizing the driver's steering input. A camera, mounted at the top of the windshield just above the rear-view mirror , scans

4745-409: The vehicle's lane. Kia Motors offered the 2011 Cadenza premium sedan with an optional lane departure warning system (LDWS) in limited markets. This system uses a flashing dashboard icon and emits an audible warning when a white lane marking is being crossed, and emits a louder audible warning when a yellow-line marking is crossed. This system is canceled when a turn signal is operating, or by pressing

4818-420: The viability of public transportation and active transport modes like walking and cycling. In cities heavily dependent on sedans, air pollution, noise, and traffic fatalities often increase, posing public health risks and environmental challenges . Lane-departure warning There are four types of systems: Another system is the emergency lane keeping (ELK). The emergency lane keeping applies correction to

4891-464: Was also released with a speed assist feature where the front facing camera reads the traffic speed limits using the technology of computer vision character recognition system, and then conveys it to the car. On roads where traffic signs are absent, it relies on the GPS data. When the car moves away from a lane at above 30 miles per hour (48 km/h), the system beeps and the steering wheel vibrate, alerting

4964-487: Was also used to describe the Škoda 1101/1102 introduced in 1946. The public popularized the name for a two-door model and was then applied by the automaker to the entire line that included a four-door sedan and station wagon versions. In the United States, the notchback sedan distinguishes models with a horizontal trunk lid. The term is generally only referred to in marketing when it is necessary to differentiate between two sedan body styles (e.g., notchback and fastback) of

5037-571: Was announced that the electric XJ successor was cancelled for the present. The company said: "Following a thorough technology review against the exponential change in the automotive industry, we concluded that the planned XJ replacement does not fit with our vision for a reimaged Jaguar brand." As reported by Richard Porter of Sniff Petrol in August 2022, the prototypes of the cancelled successor still existed and were SORN, and subsequently found out other prototypes existed and were still being tested on

5110-517: Was developed by the United States company Iteris for Mercedes Actros commercial trucks. The system debuted in 2000, and is now available on many new cars, SUVs, and trucks. In 2002, the Iteris system became available on Freightliner Trucks ' North American vehicles. In both these systems, the driver is warned of unintentional lane departures by an audible rumble strip sound generated on
