FAULT TOLERANT NETWORKING OF SQUIBS AND SENSORS IN ADVANCED PASSENGER RESTRAINT SYSTEMS

The increased complexity of new adaptive passenger restraint systems requires implementation of a serial communication network, which connects the squibs and sensors to a central electronic module. The requirements on such a safety-critical backbone include the tolerance to serious damage of the bus wires, which may occur also during a crash event. This paper describes the concept of an in-vehicle network, combining economy, robustness and reliability with the exacting performance of high-speed multi-master communication. It requires only 2 wires for distribution of power, data, and clock in the system. The network offers real-time fault tolerance to all kinds of wiring failures, which makes this system superior to all others proposed for this application.
