PROBLEM TO BE SOLVED: To suppress the decrease in driving comfort and operation safety, while quickly correcting the zero point position of an actuator. SOLUTION: An actuator control device is provided with a step motor 5 for driving a hydraulic buffer 2 that is able to change attenuation force, a controller 1 for driving the step motor 5 within a specific angle range, and a zero point switch 10 for detecting a zero-point position. Thus, the step motor 5 is driven by a specific angle X, and returned to the zero-point position when the zero-point switch 10 cannot detect the zero-point position if an instruction value from the controller 1 is the zero-point position. Therefore, the drive position of the step motor 5 is returned to the zero-point position only by one turn, when the zero-point position cannot be detected during this period. |
