Abstract:
1. A method for controlling at least one drive train component of a motor vehicle which has a drive apparatus as well as a clutch apparatus arranged In the drive train, an engine control device, and a clutch control device, said method comprising the steps of: a) controlling the position of at least a first predetermined component of the drive apparatus by the engine control device, whereby at least a first operating parameter of the drive train is controlled by the engine control device; b) controlling the position of at least a second predetermined component of the clutch apparatus by the clutch control device, whereby at least a second operating parameter of the drive train is controlled by the clutch control device: c) transmitting predetermined signals between the engine control, device and the clutch control device, which affect the control activities of at least one of those control devices; and d) maintaining below a predetermined difference limit a difference between an actual engine rotational speed gradient and a predetermined output side drive train rotational speed gradient by regulating the engine rotational speed gradient at a transition between a startup phase and a drive phase of thevehicle.
