Abstract
Methods of controlling a feedback torque actuator in a steering system that includes the feedback torque actuator and an assistance actuator incorporate, for feedback torque control, generating at least one input signal with a sensor, determining a steering angle from the input signal, transforming the steering angle to a target steering-wheel torque, and controlling the feedback torque actuator via a closed loop current control to achieve the target steering-wheel torque. The assistance actuator has a high gain, thereby resulting in a low torque in the axle above the assistance actuator such that the steering-wheel torque is close to the target steering-wheel torque, whereby acceptable steering feel is achieved.
