Abstract
An electric assisted steering control strategy for a steering system for a vehicle is arranged to assist the driver in controlling the vehicle during a split mu braking operation. The steering is provided with assistance being based on at least one operational variable representing a corrective steer angle for the vehicle which is added to a main assistance torque via a driver feedback controller, and the strategy is adapted to employ an estimate of yaw moment of the vehicle as the operational variable, the yaw moment being determined by processing the speed of wheels on opposite sides of the vehicle.
