上記アクチユエータ駆動部に出力する処理手段を
設けたことを特徴とする車高制御装置。 If the current vehicle height detected by the vehicle height sensor 2 is higher than the target vehicle height set by the vehicle height changeover switch 3, a vehicle height lowering signal is output, and if the current vehicle height is lower than the target vehicle height, a vehicle height increasing signal is output. At the same time, when the vehicle speed signal detected by the vehicle speed sensor 1 exceeds the set vehicle speed, the target vehicle height is lowered by a predetermined value, and when the vehicle speed signal is lower than the set vehicle speed, the vehicle height that was lowered by the predetermined value is restored. A vehicle height control device comprising: an arithmetic processing unit 4 that returns the vehicle height to the target vehicle height; and an actuator drive unit 5 that outputs a drive signal that causes the vehicle height to match the target vehicle height based on the output from the arithmetic processing unit. , a torque distribution electronic control unit 7 outputs a signal according to the driving force distribution between the front and rear wheels, and when the output from this torque distribution electronic control unit exceeds a preset driving force distribution, a four-wheel drive state is established. A four-wheel drive state detection circuit 8 is provided to determine the target vehicle height based on the output from the four-wheel drive state detection circuit. Along with resetting the
A vehicle height control device comprising processing means for outputting a signal to the actuator drive unit to make the current vehicle height match the maximum vehicle height.
