ステアリングの制御装置。 A vehicle speed sensor whose output pulse or output voltage increases as the vehicle speed increases; and the power actuator that reduces the flow rate of hydraulic fluid supplied to the power actuator as the vehicle speed increases based on the output of the vehicle speed sensor. A control device for vehicle speed sensitive power steering, comprising a control circuit for driving an electromagnetic control valve provided in a bypass passage that bypasses the vehicle speed sensor, the control device is provided with a control circuit for driving an electromagnetic control valve provided in a bypass passage that bypasses A means for detecting via an operational amplifier that operates based on a value change, and a correction control means having an operational amplifier that drives the electromagnetic control valve so as to reduce the flow rate of the hydraulic oil supply when the disconnection is detected. Features a vehicle speed-sensitive power steering control device.
