Abstract
A method for control of a vehicle's gearbox which is connected to a combustion engine and can be set to a number of different transmission ratios. When the vehicle is running in a low transmission ratio and at an engine speed below that at which the torque plateau for the low ratio is reached, in a situation where there is a reduced need for power output to propel the vehicle, determine a speed parameter for the vehicle, switch the gearbox to a higher transmission ratio than the low ratio when the speed parameter fulfills a first criterion.
