TTP/C - MULTIPLEXED COMMUNICATIONS FOR FAULT-TOLERANT AUTOMOTIVE SYSTEMS

The objective of this paper is to provide an introduction to the main features ot the Time Triggered Protocol (TTP/C) multiplexed communications protocol for fault-tolerant automotive systems. In future generations of vehicles there is a requirement for systems which provide highly dependable operation. Brake-by-wire and Steer-by -wire systems are being developed which have no mechanical/hydraulic back-up functionality in the event of an electrical system failure condition. These systems will be required to tolerate a system failure and continue to operate without catastrophic effects. The Time Triggered Protocol is a multiplexed serial communications protocol which has been developed over the past fifteen years to help meet the requirements of such systems. This paper will discuss the principles of TTP/C and explain the key elements which make it suitable for such applications. (A) For the covering abstract see IRRD E102826.
