A method relieves the burden of a driver of a motor vehicle in which the drive train is provided with a gearbox which can be operated in an automatic mode and a manual mode. The method comprises the following automatic steps: a) detection whether the speed of the vehicle should be adjusted, b) initiation of the adjustment if necessary, and c) the carrying out of the adjustment. During step b) and/or step c) it is determined on one or several occasions whether the gearbox is operating in an automatic mode or in a manual mode in order to trigger a change into the automatic mode of the gearbox if the gearbox is operated in the manual mode.

Adjustment of the speed of a motor vehicle with an automatic gearbox

On recognition of a slow driving condition within which a creeping function is activated, a set wheel torque is derived by a wheel torque interpretation (), such that firstly a target speed is achieved and subsequently the vehicle is maintained within a speed range about the target speed.
