Abstract
An automotive activity control system controls vehicular driving activity, such as power distribution for delivering driving torque generated by prime mover of the vehicle to primary and secondary driving wheels, vehicular braking operation for preventing the road wheels from causing skidding during braking operation, vehicular attitude. The control system includes acceleration sensor, such as a longitudinal acceleration sensor, a lateral acceleration sensor, a vertical acceleration sensor for monitoring a vehicular driving behavior and providing control parameter for activity control. The control system detects faulty condition of the acceleration sensor for taking place fail-safe operation. Particularly, the control system detects faulty condition of the acceleration sensor to generate sensor signal representative of abnormal or impossible acceleration resulting in malfunction of activity control.
