Abstract: The invention relates to a method and an arrangement for starting or stopping a motor-driven motor vehicle having motor functions (1) and motor-independent vehicle functions (5) which can be used independently of the type of drive and independently of the type of motor start or motor stop. For a start operation or a stop operation, at least one command to the motor functions (1) to start or stop the motor (15) of the motor vehicle is imparted by the vehicle functions (5) via an interface (10). At least one status datum as to the motor (15) and/or the motor functions (1) is transmitted by the motor functions (1) via the interface (10) to the vehicle functions.

Abstract: A method and an arrangement automatically restarts a drive unit (1) when there is an unintended stalling of the drive unit (1). In the case of stalling, checks are made as to whether the drive unit (1) was already in a steady-state condition directly before the stalling, as to whether the stalling took place because of an operator input, especially at an input unit (5) and as to whether a force-tight connection between the drive unit (1) and a transmission (25 or 80) is present. A restart of the drive unit (1) is automatically initiated when: the drive unit (1) was already in a steady-state condition directly before the stalling; when the stalling took place in a departure from the operator input; and, when the force-tight connection between the transmission (25 or 80) and the drive unit (1) is interrupted.

Abstract: The invention is directed to a method and an arrangement for automatically restarting a drive unit (1) including an internal combustion engine of a motor vehicle. The method and arrangement provides for an automatic restart when there is an unintended stalling of the drive unit (1). In the case of a stalling of the drive unit (1), a check is made as to whether the drive unit (1) was already in a steady-state condition directly before the stalling. Furthermore, a check is made as to whether the stalling of the drive unit (1) took place because of an operator input, especially at an input unit (5). In addition, a check is made as to whether a force-tight connection between the drive unit (1) and a transmission (25 or 80) is present.
