Abstract:
1. A method for monitoring a starting process of a motor vehicle having a semi-automatic shifting system, a drive train with a driving motor, a torque transfer system and a transmission, a controller and an actuator controlled by the controller for actuating the torque transfer system, the method comprising the steps of: a) detecting whether starting is requested; b) detecting whether starting occurs following a clear starting request; c) if, despite a starting request, no starting occurs, increasing the drive motor rotational speed, and optionally slightly disengaging the torque transfer system, which generally allows the drive motor to build greater torque than is typically required during normal operation of the starting process; d) checking whether measures initiated result in starting, and repeating step c) if no starting has occurred; e) forcibly engaging the torque transfer system after a specifiable time period, if the measures initiated in step c) still do not result in starting, as a result of which the higher torque present at the driving motor is promptly transmitted to wheels of the motor vehicle, wherein a process, regulated during normal operation, is replaced by a controlled process; f) protecting components required for starting from destruction, if the measures initiated in steps c) and e) do not result in starting of the motor vehicle, wherein after at least one of another specifiable time period and when a threshold value for a stored clutch energy has been exceeded, engine torque is reduced by intervention; g) resetting a failed starting process by canceling gas pedal actuation; and h) enabling renewed starting attempts.
