Suspension cylinder control system for motor vehicles

Abstract

A suspension cylinder control system for motor vehicles for preventing a body roll occurring when a vehicle is rounding a curve at a high speed, a nose dive on braking, and a nose up occurring when a dumping body is raised in an unloading position, and also for acquiring the optimum suspension characteristics in accordance with a vehicle load and speed. The control system comprises suspension cylinders 4 mounted between a vehicle body 1 and right and left front and rear wheels 2, 3; a pressure sensor 6 which detects the inside pressure of these suspension cylinders; a steering angle sensor 7 of a steering wheel 5; a brake sensor 8; a vehicle speed sensor 9; a dump lever position sensor 14; and a controller 10 which receives signals from these sensors and outputs a damping force changeover signal to an air solenoid valve device 11 which controls a damping force changeover actuator 12 of the suspension cylinders in accordance with the input signal.
