Byteflight (Figure 4.75) is a protocol designed for use with safety-critical systems such as air bags and seat belt tensioners. It has a high fault tolerance and allows high speed data. It is known as a flexible time division multiple access (FTDMA) protocol. Because of its flexibility, it can also be used for body and convenience functions such as locking, windows and seat control.

The FlexRay protocol standard was developed originally by the BMW group as a ByteFlight passive protocol for airbag release and other short-time release applications. Former Daimler-Chrysler joined BMW to improve and further develop the ByteFlight for by-wire applications to ultimately become the FlexRay protocol. The FlexRay consortium is integrated by several OEMs, Tier 1 suppliers and several silicon vendors (automotive electronic circuitry manufacturers). The main objective of the FlexRay Consortium is to develop (with the collaboration of all its members) the specifications of the FlexRay protocol as a communication standard for on-board vehicle communication. The study of the FlexRay standard shows that in order to achieve this intensive collaboration among the parties involved, a common goal is required. All parties involved agreed that the common goal would be to extend the technological and financial resources of the FlexRay Consortium. In this regard, the two Engineering Directors (ED) of automotive applications from a major silicon vendor and the Research Director (RD) of an automotive consultant participating in the case study agreed on the importance of strong cooperation among parties. The ED of a silicon vendor located in Northern Europe claimed that for automotive electronic purposes:Automotive innovation is only attainable by the strong cooperation of OEMs, Tier 1 and other suppliers…
