The flexray networks in the modern motorcars

Advancing the evolution of motor cars, understood as complex mechatronic systems are connected with the ever emerging constrains on coordination between the components of the system objects. Adopted by all environment related to the automotive, the way of communication between the vehicle components via network for data exchange, connected with the necessity to keep up with increasing demands on the transmission speed and level of security. The answers to these requirements concerning the ways to control x-by-wire or complex mechanism to optimize the operation of the engine, seems to have been created by the big automobile companies FlexRay protocol. The article presents the basie features of this method of communication that allows for a 10 fold increase in data rates compared to the conventional CAN network. The remaining features of transmission such as reliability and level of time determinism, which are important for control systems are discussed later in the paper. Included in the summary comments indicate potential further developments and the possibilities of the application if this method of transmission in automotive applications.
