Abstract:
A method for control of a vehicle gearbox which is automatically controlled by a control system. The control system's choice of transmission ratio is influenceable by the vehicle's driver. The control system chooses an initial transmission ratio for moving off stationary. The method includes determining a first initial transmission ratio by using the control system, and determining a second initial transmission ratio indicated by the vehicle driver. The gearbox is set to the second initial transmission ratio indicated by the driver when the second ratio is higher than the first initial transmission ratio determined by the control system.
