Method and electronic control unit for controlling a brake system of a motor vehicle

A method for controlling a brake system (12) of a motor vehicle (2), which system can be controlled by an electronic control unit (14) and which has wheel brakes (26a, 26b, 28a, 28b), which can be actuated by a pressure medium, and control devices for carrying out an anti-lock function (ABS) and for carrying out a roll stability control function (RSC), the method comprising;

• executing, during cornering or in the event of a sudden evasive movement defining a bend, a roll stability control function by the electronic control unit, and braking the motor vehicle (2) by introducing a brake pressure into the wheel brakes (26a, 26b, 28a, 28b) on account of a determined risk of tilting about the longitudinal axis (84) of the motor vehicle, wherein the determined risk is determined by the electronic control unit and the braking is controlled by the electronic control unit;
• starting an ABS control operation by the electronic control unit,
• wherein, with the start (t1) of the ABS control operation on a brake pressure (pB_KI) of the wheel brake (26b;
• 28b) on the inside of the bend on at least one motor vehicle axle (4;
• 8), increasing the brake pressure (pB_KA) of a wheel brake (26a;
• 28a) on the outside of the bend, and
• lowering the brake pressure (pB_KA) of the at least one wheel brake (26a;
• 28a) on the outside of the bend with an end of the ABS control operation (t3).
