In a motor vehicle having a brake system and a drive train, the brake system comprises a vehicle movement dynamics controller (10), a control group (40) for actuating brakes and a hydraulic unit with pressure medium supply (25, 27, 30) and wheel-specific hydraulic valves (43.sub.LV, 43.sub.RV, 43.sub.LH, 43.sub.RH) for activating the individual wheel brake cylinders (12.sub.LV, 12.sub.RV, 12.sub.LH, 12.sub.RH), and the drive system has at least one drive train (2, 3; 5, 7, 8) in which a controllable clutch (6) is arranged, which clutch (6) is activated by a clutch actuation means (40.sub.K), a hydraulic valve (43.sub.K) and an actuator (16) In order to make the vehicle as a whole cheaper but also bring about a functional improvement, the clutch controller of the drive system is integrated into the vehicle movement dynamics controller (10) of the brake system, and the hydraulic valve (43.sub.K) for activating the clutch (6) is connected to the pressure medium supply (25, 27, 30) of the brake system, and the modular control group 11.
