調整式サスペンシヨンの制御装置。 The amount of working fluid supplied and discharged to the vehicle height adjustment actuator is controlled by a solenoid valve, and the control means for the solenoid valve controls the vehicle height according to the deviation between the specified target vehicle height signal and the actual vehicle height signal from the vehicle height sensor. In a control device for a vehicle height adjustable suspension configured to obtain a high control signal and drive the solenoid valve with a duty output of a duty ratio based on this vehicle height control signal, a failure of the vehicle height sensor is detected in the vehicle. The present invention is characterized in that the control means is configured to determine the duty output based only on the target vehicle height signal instead of the vehicle height control signal when a failure of the vehicle height sensor is detected. Control device for vehicle height adjustable suspension.
