Abstract:
1. A method for operating a plurality of drive control units respectively assigned to a plurality of drives of a motor vehicle, the method comprising: receiving at a master control unit, presettings relating to a total torque which is to be applied jointly by the plurality of drives of the motor vehicle, the master control unit acting as a hybrid control unit; performing an interrogation process by outputting an interrogation from the master control unit to an immobilizer control unit; when the interrogation is output to the immobilizer control unit, sending a signal from the master control unit to at least one slave drive control unit to communicate performance of the interrogation process, so that the at least one slave drive control unit also transmits an interrogation to the immobilizer control unit; individually assigning, at the master control unit, partial drive torques respectively to the plurality of drives; and outputting at least one request signal from the master control unit only if the immobilizer control unit has returned an enable signal, each at least one request signal being used to communicate one of the partial torques to a corresponding slave drive control unit so that the at least one slave drive control unit outputs a control signal to communicate drive torque information to the corresponding drive only if the immobilizer control unit has returned an enable signal to the at least one slave drive control unit.
