Abstract
A procedure for controlling a start-up assistant control of a vehicle with a transmission, an automatically controllable clutch and at least an automatically controllable brake affecting the wheels of the vehicle, which can be activated by the driver to halt the vehicle and which with the start-up assistant control unit increases the jerking degree of the clutch on activation of a starting operating system and which at least releases the brakes. The jerk degree of the clutch, which signals the brakes to be released is selected dependent on the operating reactions of the drive train actuators, derived from the current accelerator pedal position and/or accelerator pedal adjustment speed. It can be guaranteed by considering the dead time between the issuance of a release instruction of the brakes and the actual release of the brakes along with, release of torque of the engine, the desired torque corresponds to the brake.
