Abstract: An operating method for a hybrid vehicle having at least two drive engines, of which the first drive engine is a combustion engine with internal combustion and can be supplied with fuel from a first energy storage device, and a second drive engine, which can be supplied with energy from a second energy storage device. In order to determine a control command with which the first drive engine can be shut off the method includes determining a state value for the filling degree of the first energy storage device. The method also includes detecting a filling degree of the second energy storage device, and comparing said state value for the filling degree to a target state value. Depending on said comparison, the method also includes determining a control command for the first drive engine.

Abstract: A method and arrangement is provided for controlling a motor vehicle drive train equipped with at least one drive motor, a torque converter, an automatic transmission and at least one electronic drive control device. In the drive control device, a function module is implemented for carrying out a creep control. This creep control can be activated independently of a brake actuation, when the actual rotational speed of the driving motor is greater than a defined desired rotational speed of the driving motor, and when the actual rotational speed of the driving motor cannot be reduced because of at least one defined condition as the minimally possible rotational speed of the driving motor.

Abstract: A method for opening a closed clutch arrangement of a drivetrain for a motor vehicle. The clutch arrangement is activated in such a way that the torque which it can transmit is reduced up to an opening point at which torque can no longer be transmitted via the clutch arrangement. The clutch arrangement is placed into an intermediate slip state before the opening point is reached.
