Abstract

The invention relates to a method and a device for performing open-loop or closed-loop control of the driving stability of a vehicle and for avoiding collisions with an object located in the traffic lane. The invention also relates to a closed-loop driving stability controller. The method according to aspects of the invention comprises: determining based on environmental signals whether a critical situation in terms of driving dynamics, in particular an imminent collision, exists, calculating an avoidance path if a critical situation in terms of driving dynamics exists, determining based on a plurality of input variables pressures for individual brakes of the vehicle, and activating preparatory measures of the driving dynamics regulator, in particular dynamic switching over of closed-loop control parameters if the critical situation in terms of driving dynamics exists. The device and the closed-loop driving stability controller are suitable for carrying out the method.
