Title:
BACKWARD SPEED CONTROL UNIT FOR CAR
Document Type and Number:
Japanese Patent JPS61113540
Kind Code:
A
Abstract:
PURPOSE:To reduce the workload of a driver at backward motion of a car by automatically controlling the car speed at the backward motion of the car so as not to exceed a preset speed. CONSTITUTION:When the car speed at backward motion exceeds a preset speed, the internal pressure of a damping conduit 14 and an actuating cylinder 22 is increased because the exhaust amount of liquid of a pump 11 exceeds the flowrate in which the liquid passes through an orifice 28 and is escaped to a feed conduit 13. A piston 23 moves a piston 21 right by this pressure and brake liquid is pressurized-sent to a wheel damping device by this piston 21. As a result, the wheel damping device is operated and the car speed is decreased. Then, the number of rotations of the pump 11 is also decreased and the exhaust amount is decreased. Also, the pressure of the actuating cylinder 22 is decreased and the damping device is released. By the operation mentioned above, the speed at the time when a car goes backward is controlled so as not to exceed a preset speed.
