ABSTRACT:
A front steering gear (18) is connected with steerable front wheels (12and14) of a vehicle (10). A rear steering gear (28) is connected with steerable rear wheels (30and32) of the vehicle (10). A torque sensor (40) connected with a steering wheel (16) provides an output to a controller (42). The controller (42) effects operation of the rear steering gear (28) in response to an output of the torque sensor (40) corresponding to manual application of at least a predetermined force to the steering wheel (16). Alternatively or in addition, the controller (42) may effect operation of a rear wheel brake (50or52) which is disposed on a radially inner side of a turn in response to the output from the torque sensor (40).
