Abstract
A steering system for motor vehicles, has a steering handle, for example steering handwheel, capable of being operated by the driver. A steering actuating drive provides for the steering adjustment of steerable vehicle wheels. A steering-angle desired-value encoder is capable of being operated by the steering handle, and a steering-angle actual-value encoder operates via the steerable vehicle wheels. A regulating and control arrangement operates the steering actuating drive as a function of a comparison of the desired and actual values of the steering angle. The risk of a collision between a vehicle equipped with the steering system and an obstacle is reduced, and the steering system is suitable for steer-by-wire operation by equipping the steering system with collision prevention apparatus which determine steering angles (collision steering angles) making a collision possible between the motor vehicle and an obstacle. The regulating and control arrangement hinders or prevents the setting of a desired steering angle coinciding with one of the collision angles.
