Abstract
An operation mode of a first actuator engaged with a steering rack is determined. An operation mode of a second actuator engaged with a steering column is determined. The operation mode of one of the first and second actuators is adjusted upon detecting a failure in the other of the first and second actuators. At least one of the steering rack and the steering column is actuated based on the operation mode. In an angle control mode, a predetermined steering angle is provided to the first and second actuators to adjust the steering rack according to the steering angle. In a torque control mode, a steering column torque from a torsion sensor disposed on the steering column is provided to the first and second actuators to adjust the steering rack according to the steering column torque.
