  • Patent number: 7677352
    Abstract: A process for steering a motor vehicle having a superimposition steering system, in which a steering angle input by the driver and an additional angle (supplemental angle) are detected, and in which the steering angle input can be superimposed with the supplemental steering angle in accordance with additional values, particularly driving dynamic values, by a superimposition actuator, such as an electrical motor, and can be superimposed by a superimposition gear in order to adjust a resulting steering angle. A value for a gear input angle of the superimposition gear is determined in accordance with the resulting steering angle of the steering system and in accordance with a value that is directly dependent on the supplemental steering angle or describes the supplemental steering angle.
