Abstract: A method for steering a vehicle that comprises a steering system with a steering wheel and a front axle as well as a rear axle with wheels, wherein it is provided that a direction of the vehicle is adjusted manually by a driver of the vehicle by adjustment of a steering wheel angle of the steering wheel, as a result of which, for the wheels of at least one of the axles, a steering angle is adjusted, which is obtained from the steering wheel angle plus a superposition angle, wherein, through an automatically adjustable steering ratio for the wheels of at least one of the axles, a ratio of the steering wheel angle to the steering angle for the wheels is set, wherein the vehicle travels into a curve on a circular path with a radius at a speed with a first value, wherein a steering wheel angle is adjusted by the driver.

Abstract: A method for control of a rear-axle steering of a motor vehicle. A steering angle of wheels of a rear axle is set. Upon reaching a predetermined lateral acceleration of the motor vehicle, the steering angle and/or the gradient of the steering angle of the wheels of the rear axle is limited as a function of a coefficient of friction of a roadway surface on which the motor vehicle is moving.
