Abstract
A method and a system for vehicle steering control by controlling a feedback torque actuator () in series with an angle overlay actuator () in a vehicle steering system () to provide a target feedback torque and a target overlay angle. The feedback torque actuator () is arranged above the angle overlay actuator (). The angle overlay actuator () is controlled so that a variable steering ratio and an additional overlay angle are provided, and the feedback torque actuator () is controlled using a reference generator so that the torque is controlled to provide a target steering feel, resulting in the angle overlay being controlled at the same time as the steering-wheel torque being controlled whereby a target overlay angle and a good steering feel are achieved.
