Abstract

The invention concerns a method for controlling a starting aid of a motor vehicle, in particular of a bus. The release of the starting aid takes place as follows: reduction of the braking pressure in accordance with a predetermined first gradient; simultaneous detection of the rotational direction of an output shaft of a transmission of the motor vehicle or of another component which rotates as a function of the rotational speed of the drive wheels; upon detection of a rotational-direction signal which indicates forward travel of the motor vehicle, continuation of the reduction in the braking pressure in accordance with the predetermined first gradient and upon detection of another signal, continuation of the reduction of the braking pressure by way of a second gradient which is reduced in comparison with the first gradient or an increase in the braking pressure.
