ことを特徴とするサスペンシヨン制御システム。 In a suspension control system that operates by receiving as one piece of information a signal from a road surface sensor that detects the road surface condition by the rate of change in the reflected wave intensity of ultrasonic waves that are continuously transmitted to the road surface, Equipped with a sudden braking determination circuit that determines that the vehicle is braking suddenly and stops detection by the road surface sensor when any one or more of forward acceleration, brake switch speed, and brake force exceeds a predetermined value. The suspension control system is characterized by a road surface sensor that detects an obstacle in front of the vehicle that causes sudden braking to prevent malfunctions.
