Abstract

A method for resetting a steering wheel of a motor vehicle having electric power assisted steering, with a resetting torque being determined in order to move the steering wheel from a diffracted steering position to a neutral position. The resetting torque differs for low and high friction values wherein a signal produced in response to a determined yaw rate is introduced into the determination of the resetting torque. The contribution of the yaw-rate based resetting torque to the total resetting torque increases as the vehicle speed increases.
