发明名称 METHOD AND DEVICE FOR AUTOMATIC OR SEMIAUTOMATIC SELECTION OF A BETTER STARTING GEAR IN A VEHICLE
摘要 Method and a device for automatic selection of a better starting gear in a vehicle, including the steps of engaging a first starting gear, on driver demand controlling propulsion torque as to attempt to achieve a first take off, if the first starting gear is too high interrupting the first take off and automatically braking the vehicle, engaging a second adapted starting gear which is a lower gear compared to the first starting gear, controlling propulsion torque as to attempt to achieve a second vehicle take off, and if the second vehicle take off attempt results in a transmitting of torque to driven wheels of the vehicle being enough as to perform a take off then stop braking the vehicle. An incorrectly selected starting gear can thus be automatically changed. The starting gear change can be performed in an uphill situation.
