Apparatus for controlling steer angle of rear wheels of vehicle.

摘要

A rear wheel steer angle controlling appsratus for controlling the steer angle of rear wheels (12) of vehicles having steerable front wheefs (6) and rear wheels (12). The steering wheel (1) steers the front wheels (61, and detecting means (20) detects the steering wheel displacement and generates a signal which is fed to a judging circuit (22) for judging the speed of operation of the steering wheel (1) An actuator mechanism (28) for controlling the angle of the rear wheels (12) is controlled by a control circuit (24) connected to the judging circuit (22) so that the rear wheels (12) are steered counter to the front wheels (6) when the steering wheel (1) is operated at high speed, and are steered in the same direction as the front wheels (6) when the steering wheel is operated at low speed.
