Abstract

A drive and braking arrangement for a motor vehicle has at least one electric motor which drives the motor vehicle in dependence on the setting of an accelerator pedal. A forward drive or reverse drive selector (15) adjusts the driving direction of rotation of the electric motor, and a sensor is provided for detecting the driving speed of the motor vehicle. In order to control the braking force of a friction brake arrangement acting on at least one wheel of the motor vehicle, an actuating drive is provided which is set to a braking position by an electronic control unit when the accelerator pedal remains in a driving position for longer than a predetermined period of time and at the same time the detected driving speed is zero and/or when the sensor associated with the control unit detects an actual movement of the motor vehicle in the direction opposite to the driving direction selected at the selector.
