Abstract
A method of controlling a rolling or a coasting function of a vehicle, such as a commercial vehicle, having a drive train including a drive motor, an automatic or automated transmission that is controllable by transmission controls, a controllable shifting mechanism for interrupting the flow of power in the drive train, and a driving speed control device. The flow of power in the drive train is interrupted in a suitable driving situation. In order for the rolling or the coasting function to be exploited as efficiently as possible, and still be terminated safely and comfortably, the flow of power in the drive train is restored depending on a selectable difference in speed (Δv_F_T) between the current vehicle speed (v_F) and a speed limit (v_T) set by the driving speed control device.
