Abstract

A method for starting or stopping a vehicle on a gradient. In order to protect the clutch ( 12 ) against overheating and therefore against excessive wear during the actuation of at least one brake ( 48 ) and simultaneous pressing of the accelerator pedal ( 44 ), a torque reduction in the form of a torque reduction request is transmitted to the engine control unit ( 40 ) taking into account the position of an accelerator pedal, and a reduced torque is transmitted to the clutch on the basis of said torque reduction request.

Claims (14)

1. A method for accelerating a vehicle from a stop on a gradient, comprising:

transmitting a moment from a drive engine ( 10 ), which is connected to an engine control unit ( 40 ) for electronic moment control, to an automated clutch connected to said drive engine, wherein a downward gradient force impacting the vehicle is counteracted by using at least one pedal or parking brake;

measuring a position of an accelerator pedal using a sensor;

transmitting a moment reduction in the form of a moment reduction request to the engine control unit ( 40 ) as a function of the position of the accelerator pedal; and,

transmitting a reduced moment to the clutch ( 12 ).

2. The method according to claim 1 , further comprising generating a brake force by actuating at least one brake as a precondition for the request to the engine control unit ( 40 ) to reduce the moment.

3. The method according to claim 2 , further comprising implementing the moment reduction through an electronic ramp after the brake force has been reduced by disengaging the brake.

4. A method for accelerating a vehicle from a stop on a gradient, comprising:

transmitting a moment from a drive engine ( 10 ), which is connected to an engine control unit ( 40 ) for electronic moment control, to an automated clutch connected to said drive engine, wherein the downward gradient force impacting the vehicle is counteracted by using at least one pedal and parking brake;

measuring a position of an accelerator pedal using a sensor;

transmitting a moment reduction in the form of a moment reduction request to the engine control unit ( 40 ) as a function of the position of the accelerator pedal; and,

transmitting a reduced moment to the clutch ( 12 ).

5. The method according to claim 4 , further comprising generating a brake force by actuating at least one brake as a precondition for the request to the engine control unit ( 40 ) to reduce the moment.

6. The method according to claim 5 , further comprising implementing the moment reduction through an electronic ramp after the brake force has been reduced by disengaging the brake.
