Abstract
A nontrack-bound vehicle with arbitrarily steerable front wheels includes an additional rear-wheel steering system that operates automatically or may be switched to automatic operation and controls or regulates the steering angle of the rear wheels as a function of the steering angle of the front wheels and of further parameters. The additional rear-wheel steering system switches in a parameter-dependent manner between a drive-away mode and a normal mode to improve maneuverability and to reduce the swinging out of the rear during the drive-away mode. In the drive-away mode, the steering angle of the rear wheels is controlled or regulated so that the rear wheels are not adjusted beyond a steering angle assumed when the vehicle last halted.
