FlexRay is an automotive network communications protocol developed by the FlexRay Consortium to govern on-board automotive computing. It is designed to be faster and more reliable than CAN and TTP , but it is also more expensive. The FlexRay consortium disbanded in 2009, but the FlexRay standard is now a set of ISO standards, ISO 17458-1 to 17458-5.

#1732801893457456-429: Is mainly used in aeronautic and automotive sectors. FlexRay supports data rates up to 10 Mbit/s , explicitly supports both star and bus physical topologies, and can have two independent data channels for fault-tolerance (communication can continue with reduced bandwidth if one channel is inoperative). The bus operates on a time cycle, divided into two parts: the static segment and the dynamic segment. The static segment
494-452: Is merely delayed by 2 cycles. Errors near the middle of 8-cycle region are canceled. Errors near the boundary of 8-cycle region may affect the boundary bit. At each time, only one ECU writes to the bus . Each bit to be sent is held on the bus for 8 sample clock cycles. The receiver keeps a buffer of the last 5 samples, and uses the majority of the last 5 samples as the input signal. Single-cycle transmission errors may affect results near
532-500: Is preallocated into slices for individual communication types, providing stronger determinism than its predecessor CAN . The dynamic segment operates more like CAN, with nodes taking control of the bus as available, allowing event-triggered behavior. The FlexRay Consortium was made up of the following core members: There were also Premium Associate and Associate members of FlexRay consortium. By September 2009, there were 28 premium associate members and more than 60 associate members. At

#1732801893457836-796: The S7 began in spring 2012. Reviewers have cited the Mercedes-Benz CLS-Class as the inspiration to the Audi A7 in the four-door executive sedan market. The following internal combustion engines are available, with variations dependent on market. In the ICOTY Awards, the Audi A7 was named the International Car of the Year in 2012. AutoWeek named the Audi A7 as the Best of the Best/Car for 2012. Esquire named
874-414: The boundary of the bits, but will not affect cycles in the middle of the 8-cycle region. The value of the bit is sampled in the middle of the 8-bit region. The errors are moved to the extreme cycles, and the clock is synchronized frequently enough for the drift to be small. (Drift is smaller than 1 cycle per 300 cycles, and during transmission the clock is synchronized more than once every 300 cycles.) All
912-427: The communication is sent in the form of frames. The message consists of bytes { x 0 , x 1 , … , x m − 1 } {\displaystyle \{x_{0},x_{1},\dots ,x_{m-1}\}} , packed in the following way: If nothing is being communicated, the bus is held in state 1 (high voltage), so every receiver knows that the communication started when
950-455: The communication was received correctly. The green cells are sampling points. All except the first are synchronized by the 1->0 edge in the transmission fragment shown. When developing and/or troubleshooting the FlexRay bus, examination of hardware signals can be very important. Logic analyzers and bus analyzers are tools which collect, analyze, decode, store signals so people can view
988-428: The drift may skew the clock no more than 1 cycle. Small transmission errors during the receiving may affect only the boundary bits. So in the worst case the two middle bits are correct, and thus the sampled value is correct. Here's an example of a particularly bad case - error during synchronization, a lost cycle due to clock drift and error in transmission. Errors that happened in the example: Despite so many errors,
1026-481: The end of 2009, the consortium disbanded. The first series production vehicle with FlexRay was at the end of 2006 in the BMW X5 (E70) , enabling a new and fast adaptive damping system. Full use of FlexRay was introduced in 2008 in the new BMW 7 Series (F01) . The FlexRay system consists of a bus and electronic control units (ECUs). Each ECU has an independent clock. The clock drift must be not more than 0.15% from
1064-495: The liftback A7 compared to the A8's framed doors. The A7L could be seen as a closer competitor to the BMW 8 Series Gran Coupé than the standard A7. The engines are the same as those used in the liftback version, including the top-of-the-line 3.0-litre TFSI engine with 340 PS (250 kW; 335 hp) and 500 N⋅m (369 lbf⋅ft) of torque.

1140-465: The reference clock, so the difference between the slowest and the fastest clock in the system is no greater than 0.3%. This means that, if ECU-s is a sender and ECU-r is a receiver, then for every 300 cycles of the sender there will be between 299 and 301 cycles of the receiver. The clocks are resynchronized frequently enough to assure that this causes no problems. The clock is sent in the static segment. Correct averaging in case of no errors. The signal

The steering rack has continuously variable assistance and ratio, and there is an optional dynamic all-wheel steering system. The RS7 comes standard with four internally vented diameter brake discs with 390 mm (15.4 in) diameter front discs and black or optionally red painted six-piston calipers, which can be upgraded to 420 mm (16.5 in) carbon fiber ceramic discs with anthracite grey painted calipers. They are mounted behind polished 20-inch forged wheels in

1216-402: The top speed to 280 km/h (174 mph) and 305 km/h (190 mph) respectively. The RS 7 Performance will accelerate from 0 to 100 km/h (0 to 62 mph) in 3.7 seconds and 0 to 200 km/h (0 to 124 mph) in 12.1 seconds. Despite the improved performance, the fuel economy and CO 2 emissions ratings are unchanged from the standard RS 7. Audi unveiled
1254-408: The voltage drops to 0. The receiver knows when the message is complete by checking whether BSS0 (1) or FES (0) was received. Note that 8-cycle per bit has nothing to do with bytes. Each byte takes 80 cycles to transfer. 16 for BSS0 and BSS1 and 64 for its bits. Also note that BSS0 has value 1, and BSS1 has value 0. Clocks are resynchronized when the voted signal changes from 1 to 0, if the receiver

It was introduced to the Vietnamese market in October 2018 and to the Thai market in February 2019. FlexRay FlexRay is a communication bus designed to ensure high data rates, fault tolerance, operating on a time cycle, split into static and dynamic segments for event-triggered and time-triggered communications. It
1330-567: Was first unveiled at the 2019 Frankfurt Motor Show . Specifications In April 2021, Audi launched the three-box sedan version of the A7, called the A7L. It is only sold in China as the first Audi model manufactured by the SAIC Volkswagen joint venture. The A7L has a slightly longer wheelbase while being shorter overall than the Audi A8 (non-LWB); the A7L also has frameless doors like
1368-407: Was in either idle state or expecting BSS1. As synchronization is done on the voted signal, small transmission errors during synchronization that affect the boundary bits may skew the synchronization no more than 1 cycle. As there are at most 88 cycles between synchronization (BSS1, 8 bits of the last byte, FES and TES - 11 bits of 8 cycles each), and the clock drift is no larger than 1 per 300 cycles,
1406-572: Was launched in China in December 2018. In April 2021, an additional extended wheelbase three box sedan variant, called the A7L, was launched in China. The A7L is manufactured by SAIC-Volkswagen as one of the first Audi products to be produced by SAIC. The A7 Sportback MK2 Type C8/4K was launched in Pakistan in 2019, one year after its launch in India. As of 2017, the second generation of the Audi A7
