The invention relates to a method for operating a motor vehicle having a brake system with a hydraulic brake device having a controllable pressure generator and a friction brake which can be hydraulically connected to the pressure generator, and an electric machine which can be operated in the form of a generator in order to decelerate the motor vehicle; a brake system having a running pedal and a brake pedal, a deceleration torque of the brake system being required by actuating the brake pedal and by releasing the running pedal; the brake system is controlled in accordance with a first deceleration torque demanded by the travel pedal and a second deceleration torque demanded by the brake pedal in such a way that, at rotational speeds above a predefinable limit rotational speed of the electric machine, the demanded total deceleration torque is achieved solely by the electric machine and, in the case below the limit rotational speed, the demanded total deceleration torque is achieved solely by the brake pedal. The required total deceleration torque is transmitted from the electric machine to the brake device by controlling the pressure generator. At or above the limit rotational speed, the first deceleration torque requested by the travel pedal is reduced in accordance with the second deceleration torque requested by the brake pedal.
本发明涉及用于运行机动车的方法,机动车具有制动系统,制动系统具有带有可控制的压力产生器和可与压力产生器液压连接的摩擦制动器的液压制动装置和电机,为了使机动车减速,电机能以发电机方式运行;并具有行驶踏板和制动踏板,通过操纵制动踏板并通过松开行驶踏板可要求制动系统的减速力矩;制动系统根据由行驶踏板要求的第一减速力矩和由制动踏板要求的第二减速力矩被控制为,使得在电机的可预设的极限转速以上的转速中,要求的总减速力矩仅由电机实现,在低于极限转速的情况下,要求的总减速力矩通过控制压力产生器从电机传输到制动装置。在极限转速以上,根据由制动踏板要求的第二减速力矩减小由行驶踏板要求的第一减速力矩。
