Abstract

An automatic brake and steering system and method for a vehicle contains a sensor unit for sensing vehicle state and characteristic variables, and ambient conditions. Furthermore, a control unit and actuator devices are provided for setting the vehicle brake system and/or the vehicle steering system. In order to be able to carry out automatic avoidance maneuvers with maximum safety, an avoidance route is determined if there is an obstacle in the path of the vehicle. Thereby, if there is a further obstacle on the avoidance route, the strategy for determining the avoidance route is applied once more. If it is not possible to find a collision-free avoidance route, that route on which the difference between the remaining braking distance and the remaining distance from the obstacle is smallest is selected.
