A method for stabilizing a vehicle including a trailer drawn by the vehicle including the steps of: determining the yaw rate of the vehicle; determining the reference yaw rate in a vehicle model; producing a difference value from the yaw rate and the reference yaw rate; weighting the difference value with a signal describing the steering dynamics; producing a signal to determine the side of intervention and/or the wheel of intervention and/or the steering angle direction of the vehicle from the tendency to change of the weighted difference value, and applying a counteracting moment depending on the amplitude and the tendency to change of the weighted difference value.

Process and device for stabilizing a vehicle

In an unstable driving situation of a vehicle with an electronically controlled hydraulic brake system with a front/rear split of brake circuits, for instance during a lane change, the inlet valve of one of the two front wheel brakes may be closed for the ESC in order to raise the pressure in only the other wheel brake of the brake circuit. If then the vehicle runs the risk of tipping over, ARP sets in. The vehicle path needs to be readjusted to reduce lateral forces. The ARP demands a pressure build-up in the curve-outer front wheel brake. The corresponding inlet valve will be opened for the ARP to allow a pressure build-up. However, the ESC may still demand a higher pressure on the initially actuated wheel brake to counter understeering. In this event, the inlet valve of the curve-inner wheel brake, which is under high pressure from the ESC intervention, will remain open to allow a cross-flow of brake fluid from the ESC wheel to the ARP wheel.
