ABSTRACT:
An actively controlled suspension system includes a fail-safe control system which detects abnormality of the output of a sensor to instantly perform fail-safe operation for ordering a neutral suspension mode with disabling the suspension control. The fail-safe system maintains the suspension system in the neutral mode for a predetermined period of time and performs checking of the output of the sensor after expiration of the predetermined period. The fail-safe system resumes suspension control when the sensor output as checked after expiration of the predetermined period is within a predetermined value range which is set about a known neutral position.
