Controlling for shock absorber

Abstract

Abstract PURPOSE:To change properly a damping force and improve riding quality in a variable damping force shock absorber by constitutionally increasing the damping force during a predetermined period in which detected car height exceeds a predetermined value and then reaches the neutral car height. CONSTITUTION:Car height detected by car height sensors H1L, H1R, H2C are sent to the input of an electronic controller ECH4 which obtains the average of input car height or the highest car height to determine car height A and compare it with a car height change set value A0. And when the car height A exceeds the set value A0 current is supplied to damping force actuators A1L, A1R, A2L and A2R after waiting by a predetermined Lime-lag tb to change largely the damping force. Then ECU4 detects the car height A, judges whether or not it returns to the neutral car height and changes the damping force smaller when it returns to the neutral one. Thus, th damping force can be changed every half cycle to improve riding quality.
