子制御サスペンシヨン装置。 In a suspension device that includes a spring member interposed between a wheel and a vehicle body and a spring force adjustment device that adjusts the spring force of this spring member, a G output voltage that corresponds to the longitudinal acceleration of the vehicle body is used. A sensor, a vehicle height sensor that detects the vehicle height at the front and rear of the vehicle body,
Output voltage V+α of this G sensor・Time differential value V'
exceeds a threshold, the spring force adjusting device is driven so that the spring member acts in a direction that opposes the posture control in the longitudinal direction of the vehicle body, and the vehicle height per unit time output from the vehicle height sensor is When the average vehicle height averaged at predetermined time intervals enters a first target range, the spring force adjusting device is kept in operation, and the average vehicle height reaches a second target range narrower than the first target range. 1. An electronically controlled suspension device comprising: a controller that performs return control using the spring force adjusting device when the spring force adjusts.
