Abstract
PURPOSE:To improve comfort of riding, maneuverability and safety by making use of a microcomputer, controlling a damping force based on a detected operating condition and making the damping force into the one corresponding to the operating condition. CONSTITUTION:A manual setting signal 64, a vehicle speed signal from a vehicle speed sensor 61 and a signal from a displacement sensor 62 which detects a stroke of a buffer are applied to a microcomputer 70. The most suitable characteristic is operated and an extension and contraction sides electromagnetic valves 18 and 39 are controlled by the microcomputer 70 based on those signals. Both the valves are controlled even by an acceleration sensor 63. The most suitable comfort of riding, maneuverability and safety are obtainable always as the damping characteristic is controlled according to an operating condition.
