Method for starting control unit of a motor vehicle
Abstract:
In order to achieve a comfortable starting process with low wear, a braking torque, set by the driver by way of a brake pedal, an acceleration torque, requested by the driver via the accelerator pedal, and a holding torque, required for holding a motor vehicle on a gradient, are determined, and the engagement of the starting clutch, as well as the release of the service brake, are coordinated such that during the release of the service brake, the sum of the clutch torque and braking torque corresponds to the holding torque, and the clutch torque of the starting clutch is increased by the acceleration torque only when the service brake has been largely released.
