ABSTRACT:
A method of and an apparatus for controlling rear road wheel camber of a four-wheel-steerable vehicle having front and rear road wheels steerable in the same or opposite directions. The camber with respect to ground of at least the rear road wheel on the outer side of a cornering curve followed by the vehicle is controlled. The apparatus includes detectors for detecting the direction in which the rear road wheels are steered with respect to the front road wheels, the self-aligning torque on the front road wheels, and the steering force acting on a steering wheel, camber varying devices associated with rear wheel suspensions, actuators for operating the camber varying devices, and a control unit responsive to detected signals from the detectors for applying a control signal to at least one of the actuators to control the camber of at least the rear road wheel on the outer side of the cornering curve when the rear wheels are steered.
