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.
A method of coordinating pressure demands within a brake circuit of an electronically controlled hydraulic brake system, the brake circuit comprising a pressure generator feeding a brake line which splits up into two inlet lines, two wheel brakes, each connected to the brake line via one of the inlet lines, an electromagnetically controlled inlet valve in each inlet line, the method comprising the following steps:
