ABSTRACT:
The invention relates to a process and a system for aiding a starting movement of a vehicle. Problems occur particularly when starting on a hill or on a steeply sloping road because it is difficult or impossible for the vehicle operator to simultaneously release the foot brake pedal and operate the accelerator pedal and thus provide an engine torque necessary for the corresponding starting operation. It is an object of the invention to provide a process and a system for aiding a starting movement of a vehicle by means of which the starting movement can be carried out without problems and in an uncomplicated manner and without endangering other traffic participants. In the process and system according to the invention, this is achieved in that the rest position of the vehicle is ensured by means of a braking intervention by way of an external power or secondary brake circuit if the braking force exercised by the vehicle operator is not sufficient. The engine torque generated by the driving engine of the vehicle is sensed and the braking intervention is terminated as of a defined engine torque.
