Abstract
A method is provided for automatically controlling the lateral dynamics of a vehicle with front-axle steering by determining a first desired value for the vehicle yaw velocity, corresponding to the path movement of the vehicle set by the operation of a steering element or device, and a second desired value for the vehicle yaw velocity, corresponding to the sideslip angle in the area of the unsteered rear wheels of the vehicle, and supplying the smaller of the two yaw velocity values to an automatic control device as the desired input. Upon activation of the automatic control device, the vehicle no longer precisely follows the driver's wish as set by the steering element but rather, follows it only approximately by adjusting the sideslip angle in the area of the unsteered rear vehicle wheels to a value that is compatible with the dynamic of a non-swerving vehicle and thereby enlarging the slip angle at the steered front wheels of the vehicle.
