A device for motor vehicle braking systems, which is designed to facilitate starting on hills. The device comprises a piston cylinder device, controlled by an electronic unit which is coupled to a pneumatic or hydraulic pressure system and acts on the brake pedal. Signals are fed to the electronic unit from a sensor for vehicle speed and direction and from a pair of sensors sensing brake pedal position and gas pedal position. When the signals from the first-mentioned sensor indicate that the vehicle has been brought to a stop after movement in a direction differing from the direction selected via the gear selector and indicated by sensor, at the same time as the two other sensors signal that the brake pedal has been depressed and the gas pedal has been released, the piston cylinder device is activated to brake the vehicle. If the accelerator is then depressed the device is deactivated and the brake is released. |
