Controller for alignment of rear wheel

Abstract

Abstract PURPOSE:To improve the property of moving into a road lane, by operating an actuator for driving the knuckle arm tie rod of a rear wheel suspension, depending on a vehicle speed change signal, through a rear wheel alignment controller for an automobile to automatically control the alignment of its rear wheel. CONSTITUTION:An electric signal corresponding to the change in the speed of a vehicle is sent from a sensor 1 to a controller 3. A specific signal corresponding to the speed of the vehicle is read from a control map 9 and applied to a solenoid valve 5 to open it to introduce pressure liquid into an actuator 6 to move a piston rod by a prescribed stroke. As a result, a knuckle arm is turned through a tie rod 37. The communication of the cylinder air chamber of an actuator 27, into which liquid pressure is introduced, is switched over depending on the increase or decrease in the speed of the vehicle so that the toe-in value of the vehicle is augmented for the increase in the speed or reduced for the decrease in the speed. The straight moving property and steering property of the vehicle are thus improved.
