Device for authorizing an unrestricted operating mode of a vehicle control device in the event of a failure of the ignition signal

摘要

A motor vehicle with an automated clutch in its drive train has a clutch control device for controlling the automated clutch and at least a further control device. The clutch control device and the further control device can be activated by means of an activation element which, when the ignition is switched on, sends an ignition signal VZ to the clutch control device and to the further control device. The clutch control device is or remains activated if at least one of the ignition signal VZ and an activity signal of the further control device is present.
