摘要

A permanently active roll-back safeguard system which drives the motor (1) in the appropriate opposite direction is obtained by simple control techniques which involve actuating a standstill control device (3) when an accelerator pedal (4), that determines the acceleration or speed of the vehicle (1), is in its neutral position, and driving the motor in the opposite direction, once the sense of rotation has been checked (sensor 1.1 or 6.1; sensor 5.1) and the roll-back speed has been detected (sensor 1.2 or 6.1).
