20-448: The newly developed Diesotto engine is primarily responsible for the performance achieved. In the F 700, it is used for the first time as a four-cylinder engine with a displacement of 1.8 liters and an output of 175 kW (238 hp). The torque is 400 Nm. The F 700 can accelerate from 0 to 100 km/h in 7.6 seconds. The top speed was limited to 200 km/h. The engine also features direct injection, two turbochargers, and variable compression. However,

40-421: A stereo camera instead of laser projectors. The system dubbed Magic Body Control is fitted with a road-sensing system ( Road Surface Scan ) that pre-loads the shocks for the road surface detected. Using a stereo camera , the system scans the road surface up to 15 meters ahead of the vehicle at speeds up to 130 km/h (81 mph), and it adjusts the shock damping at each wheel to account for imperfections in

60-630: A modern automobile produced after 1975 is a stub . You can help Misplaced Pages by expanding it . Active Body Control Active Body Control , or ABC, is the Mercedes-Benz brand name used to describe electronically controlled hydropneumatic suspension . This suspension improves ride quality and allows for control of the vehicle body motions, allowing for reduced body roll in many driving situations including cornering , accelerating , and braking . Mercedes-Benz has been experimenting with these capabilities for automobile suspension since

80-498: A steel coil spring and a shock absorber connected in parallel, as well as a hydraulically controlled adjusting cylinder, are located between the vehicle body and wheel. These components adjust the cylinder in the direction of the suspension strut, and change the suspension length. This creates a force which acts on the suspension and dampening of the vehicle in the frequency range up to five hertz . The system also incorporates height adjustable suspension , which in this case lowers

100-457: Is carried out by a standard three-way catalytic converter. The electric motor in the F 700 offers advantages, especially in urban driving, and provides an additional 15 kW for acceleration. Another new invention called Pre-Scan is used for the first time in the F 700. Two lidar laser scanners integrated into the headlights scan the road ahead of the vehicle and detect irregularities. The active suspension system, ABC (Active Body Control), processes

120-480: Is intended to counter the effect of centrifugal force on the occupants and is available only on rear-wheel drive models Vehicles, chronological order: Millisecond A millisecond (from milli- and second ; symbol: ms ) is a unit of time in the International System of Units equal to one thousandth (0.001 or 10 or / 1000 ) of a second or 1000 microseconds . A millisecond

140-401: The air suspension of the 1963 600 and the hydropneumatic (fluid and air) suspension of the 1974 6.9 . ABC was only offered on rear-wheel drive models, as all-wheel drive 4MATIC models were available only with Airmatic semi-active air suspension , with the 2019 Mercedes-Benz GLE 450 4MATIC being the first AWD to have ABC available. The production version was introduced at

160-460: The 1999 Geneva Motor Show on the new Mercedes-Benz CL-Class C215 . In the ABC system, a computer detects body movement from sensors located throughout the vehicle, and controls the action of the active suspension with the use of hydraulic servomechanisms . The hydraulic pressure to the servos is supplied by a high pressure radial piston hydraulic pump, operating at 3,000psi. Accumulators regulate

180-714: The ABC control unit uses the yaw rate, lateral acceleration, steering angle and road speed sensors of the Electronic Stability Program ESP®. In 2007, the Mercedes-Benz F700 concept introduced the PRE-SCAN suspension , an early prototype road scanning suspension, using lidar sensors, based on Active Body Control. In 2013 the Mercedes-Benz S-Class (W222) introduced the series production version of PRE-SCAN, but with

200-415: The control unit and the sensors, while the fast FlexRay bus connects the control unit and the vehicle electronics. Processing power is more than double that of the previous system. In 2014 the new C217 S-Class Coupe introduced an update to Magic Body Control, called Active Curve Tilting . This new system allows the vehicle to lean up to 2.5 degrees into a turn, similar to a tilting train . The leaning

220-525: The driver to adjust the suspension range for different driving style preferences. This feature allows the driver to adjust the suspension to maintain a more level ride in more demanding driving conditions. The reliable function of the ABC system requires a regular hydraulic oil change and filter replacement. The 1991 Mercedes-Benz C112 , 1995 Mercedes-Benz Vario Research Car and the 1996 Mercedes-Benz F200 already featured prototype versions of ABC. The first complete and ready-for-production version of ABC

240-485: The headlamps as “eyes” that produce a precise picture of the road's condition. From this data, the control unit computes the´parameters for the active suspension settings in order to provide the highest level of comfort. PRE-SCAN was an early prototype of Magic Body Control (with Road Surface Scan), that was introduced in 2013 on the Mercedes-Benz S-Class (W222) . The series version uses visual light twin optical stereo cameras instead of laser. This article about

260-434: The hydraulic pressure, by means of an enclosed nitrogen bubble separated from the hydraulic fluid by a membrane. A total of 13 sensors continually monitor body movement and vehicle level and supply the ABC controller with new data every ten milliseconds . Four level sensors, one at each wheel measure the ride level of the vehicle, three accelerometers measure the vertical body acceleration, one acceleration sensor measures

280-491: The information from the road irregularities to enhance driving comfort. It was introduced in production under the name Magic Body Control in 2013 in the Mercedes-Benz Type 222. PRE-SCAN suspension was an upgrade of Active Body Control . Using PRE-SCAN suspension, the car not only reacts highly sensitively to uneven patches of road surface, but also acts in an anticipatory manner. PRE-SCAN uses two laser sensors in

300-422: The longitudinal and one sensor the transverse body acceleration. As the ABC controller receives and processes data, it operates four hydraulic servos, each mounted on an air and pressurized hydraulic fluid strut , beside each wheel. Almost instantaneously, the servo regulated suspension generates counter forces to body lean , dive and squat during various driving maneuvers. A suspension strut, consisting of

320-425: The most important element of the new DiesOtto technology is the spatial ignition combustion at partial load. This is a very efficient combustion process, similar to that of a diesel engine, and is particularly advantageous at low and medium speeds. The air-fuel mixture ignites on its own. The F 700 starts like a conventional gasoline engine using a spark plug, which is also used under high loads. Exhaust gas purification

340-413: The pulsation damper was relocated to be mounted directly on the tandem pump. In 2010 a crosswind stabilization function was introduced. In strong gusts of crosswind, and depending on the direction and intensity of the wind having an effect on the vehicle, this system varies the wheel load distribution in such a way that the effects of winds are largely compensated or reduced to a minimum. For this purpose

360-430: The road. Initially only available on 8-cylinder models and above, Magic Ride Control attempts to isolate the car's body by predicting rather than reacting to broken pavement and speed humps. The ABC has undergone major modifications for the new S-Class: the wheel damping is now continuously adjustable, the spring strut response has been improved and the pump efficiency has been further enhanced. A digital interface connects

380-407: The vehicle up to 11 mm (0.43 in) between the speeds of 60–160 km/h (37–99 mph) for better aerodynamics , fuel consumption, and handling. The ABC system also allows self-levelling suspension , which raises or lowers the vehicle in response to changing load (i.e. the loading or unloading of passengers or cargo). Each vehicle equipped with ABC has an “ABC Sport” button that allows

400-514: Was introduced in 1999 on the top-of-the-line Mercedes-Benz CL-Class (C215) . In 2006, the Mercedes-Benz CL-Class (C216) introduced the second generation Active Body Control suspension, referred to as ABC Plus or ABC II in technical documentation. This updated suspension reduced body roll by 45% compared to the first generation ABC suspension. ABC Plus had an updated hydraulic system design, with shorter hydraulic lines, and
