    Abstract: A variable toe angle control system for a vehicle that can be incorporated with a fail-safe mechanism. When a fault of the system is detected, at least one of toe-angle actuators is actuated to make toe angles of two wheels agree with each other. When one of the wheels has become fixed in position without regard to a control signal supplied to the corresponding actuator, the actuator for the other wheel is actuated so as to make the toe angles of the two wheels equal to each other. When at least one toe-angle sensor is found faulty, the actuators are both actuated until the actuators reach positions corresponding to stoppers. When information for determining target values of the toe angles of the right and left wheels is found faulty, the actuators are both actuated until the actuators reach positions corresponding to prescribed reference toe positions.

    Abstract: A steering system selectively operable in one of six modes: steer-by-wire with rear steering, steer-by-wire without rear steering, electronic power assist steering (EPAS) with rear steering, electronic power steering (EPAS) without rear steering, mechanical backup manual steering with rear steering, and mechanical backup manual steering without rear steering. The steer-by-wire system includes a driver interface system (DIS), a front road wheel actuator system (FRWAS), a rear road wheel actuator system (RRWAS), and a controller for monitoring and implementing the preferred control strategy. The steering system operates normally in a steer-by-wire mode. In each of the EPAS mode and manual mode, the controller causes a clutch mechanism to engage, thus creating a mechanical linkage between the steerable member and the rack and pinion system while maintaining rear wheel assisted steering. In the EPAS mode, one of the front road wheel actuator or the reaction torque generator is available to assist in the steering operation along with rear wheel steering. Alternatively, in the manual mode, both the DIS and the FRWAS are deactivated and the vehicle is steerable through mechanical device along with the rear wheel assisted steering.
