制御システム。 A transmitter that continuously transmits ultrasonic waves towards the road surface, a receiver that receives reflected waves from the road surface, and a road condition detection device that detects and outputs the road surface condition from the rate of change in the reflected wave intensity of the received reflected waves. In a suspension control system that operates by receiving a detection signal from a road surface sensor comprising a circuit as one of the information, the received wave frequency f, which increases as the vehicle speed v increases due to the Doppler effect, reaches a predetermined minimum operating vehicle speed. The received wave frequency characteristics of the receiver are determined so as to obtain a gain when the frequency is higher than the lowest operating frequency F corresponding to V, and at low speeds just before the vehicle stops, the detection of the road surface sensor is stopped and objects in front of the vehicle are detected. A suspension control system that is characterized by preventing malfunctions.
