Abstract
In a motor vehicle having two different drives, in particular an internal combustion engine and an electric drive, there are two control units for the respective drives and a leading control unit (Hybrid), which preferably controls the internal combustion engine and assigns torque to the individual drives when there are torque requests. Corresponding request signals are sent and implemented only if the existence of a certain situation (key inserted, 'terminal) is detected by an engine immobilizer control unit (EI master). In order for not too much time to pass due to the querying of the engine immobilizer control unit, the leading control unit informs the other control units that a query is sent so that the other control units can also send a query already.
