Abstract
A method of regulating a vehicle drive-train in which actuation of an automatic starting element is regulated when starting the vehicle, and, during this regulation, monitoring a predetermined travel direction, reception of a brake release command and reception of a drive command. Furthermore, after receipt of the release command, the vehicle is held stationary, by a holding operation of the vehicle, until the drive command is received. If movement of the vehicle in a direction opposite to the predetermined travel direction is detected, actuation of the starting element is increased to a firmer engagement level. Once the driver releases the brake and until the drive command is received, if further movement of the vehicle, in the predetermined travel direction, is detected, then actuation of the starting element is decreased toward a lesser engagement level.
