Verfahren zum Behandeln von einem fehlerhaften Gerät in einem Fahrzeugkommunikationsnetz

摘要

The invention relates to a method for treating a defective device in a vehicle communications network. Said method is used to identify devices that are either defective, have been removed from the vehicle communications network or have been deactivated and to ensure that a measure is taken automatically to eliminate the defect. An extended, device-specific driver with a diagnosis function is loaded with another device in the vehicle communications network in order to send the defective device a test signal. Depending on the reaction to the test signal, the defective device is either relaunched or deactivated. If a device is removed from the vehicle communications network, this is indicated in a data base. A bus manager then informs all other devices connected to the vehicle communications network that this device has been removed from said vehicle communications network. A classification of the individual devices connected to the vehicle communications network ensures that only appropriately classified devices and not simply any device can treat the defect, hereby preventing misuse.
