Abstract
An apparatus and a process for the prevention of the rollback of a vehicle with a vehicle braking system (18), wherein a braking system (18) comprises a vehicle brake pressure modifying apparatus (20); a device (28, 34, 36) which are enabled to recognize a forward movement of the vehicle, and a brake control apparatus (16), which is connected to the vehicle brake pressure modifying apparatus (20) and the device (28). There is generated in the control apparatus (16) a signal which, upon a standstill of the vehicle, activates a brake and sensor combination (8, 28) which acts upon a transmission (2) of the vehicle, the brake and the sensor combination (8, 28) being supplementary to the brakes of the vehicle brake system (18) and, upon a recognition of a forward motion of the vehicle, the braking fluid pressure in the vehicle brake pressure modifying apparatus (20) is reduced and thus the brake and the sensor combination (8, 28) acting upon the transmission is released.
