Instant detection/diagnosis of abrupt bias fault in signals of vehicle motion sensors

摘要

A system and method for enabling an abrupt bias fault in a vehicle motion sensor (24), such as a yaw rate sensor or a lateral acceleration sensor to be both quickly and accurately diagnosed. When a potential fault is first indicated, it is signalled as true only if the vehicle is in a stable state and vehicle vibration is ruled out as a cause of abrupt signal change. Processing of signals is conducted by microprocessor. <IMAGE>
