Beschreibung
Zusammenfassung:	The invention relates to a braking method of a motor vehicle with a driving mechanism containing an electric drive and an operating and braking system. The motor vehicle is rolling against the selectable direction of travel of the driving mechanism on an inclined surface due to the downgrade weight component. According to the method, the driving torque specified value of the driving torque operating along the driving direction against the rolling movement is relatively determined with an accelerator pedal value representing the operating characteristic of the accelerator pedal. The electric drive is operated to generate a driving torque acting along the driving direction and against the rolling movement during the electricity generating operation. The driving torque specified value is exceeded the driving potential of the electric drive during the electricity generating operation as soon as the operating and braking system is controlled, so that the operating and braking system generates the additional braking torque against the rolling movement.
