ABSTRACT:
A fail detecting system for an electromagnetic actuator avoids influence of a dither signal in detection of a failure of the electromagnetic actuator. Avoidance of influence of the dither signal is achieved by performing a comparison of a suspension control command with a driver current applied to the electromagnetic actuator in absence of the dither signal. An error value between the suspension control command and the driver current obtained through the comparison is compared with a predetermined fault detecting criterion for judging a failure of the electromagnetic actuator when the error value is greater than the fault detecting criterion.
