Abstract

PURPOSE:To prevent oscillation at the time of backing up a slope so as to enhance travelling by actuating the actuator for operating of a damping force adjusting shock absorber so as to increase damping force when a vehicle goes back on an upward slope. CONSTITUTION:When a slope sensor M4 detects that a vehicle is on an upward slope and a reverse switch M5 detects that the shift position of a gearbox is in a reverse position, a damping force control mean M6 outputs a control signal to an actuator M2 based on these detected signals so as to increase the damping force of a shock absorber M3. With this arrangement, the actuator M2 increases the damping force of the shock absorber M3. With this structure, the vehicle can travel stably without generating oscillation at the time of backing up a slope.
