Method and system for assisting the start-up of a motor vehicle
First Claim
1. Method of assisting the start-up of a motor vehicle having a braking equipment (6) which is activated in the stationary state, comprising the following steps:
- determination of starting parameters characterizing an operating state of the motor vehicle in which the motor vehicle is to be brought from a stationary state into a traveling state;
determination of current operating states of the motor vehicle until an operating state is determined which is occasioned by an active connection between an engine (40) and driving wheels of the motor vehicle, and control of braking equipment (6) which is activated in the stationary state so as to reduce the braking forces generated in the stationary state in order to allow startup of the motor vehicle, characterized in that the determination of actual operating states is effected until an operating state is determined in which a current inclination of the motor vehicle has varied by a defined value relative to an inclination of the motor vehicle in the stationary state.

Abstract
The present invention provides start-up assistance for a motor vehicle having braking equipment which, in the stationary state of the mo-or vehicle, automatically or under the control of a vehicle driver summons up braking forces needed for the stationary state. To assist start-up of the motor vehicle through a reduction of the braking forces generated in the stationary state, a start-up request of a vehicle driver is determined when defined conditions, which are to be met for start-up of the motor vehicle, exist in the stationary state. Once a start-up request has been recognized, the operating state of the motor vehicle is checked until an operating state required for start-up exists. Once such an operating state is reached, the braking equipment of the motor vehicle is controlled in such a way that its braking forces generated in the stationary state are reduced to allow start-up of the vehicle.
