ON-BOARD NETWORK SYSTEM OF A MOTOR VEHICLE AND PROCESS FOR OPERATING THE ON-BOARD NETWORK SYSTEM
First Claim
1. An on-board network system of a motor vehicle having control devices configured to communicate with one another by way of at least one data bus, the on-board network system comprising:
- a desired-status storage device containing details concerning said control devices and desired data statuses for said control devices in the form of a desired-status list;
a retrieval device configured to address said control devices by way of the at least one data bus and to retrieve actual data statuses actually present in each of the control devices by means of a diagnostic protocol, wherein a result of retrieving said actual data statuses is stored in the form of an actual-status list;
a comparison device configured to compare the desired data statuses stored in the desired-status storage device with the actual data statuses determined by the retrieval device; and
a measures device which, in the event of a different between the desired data statuses and the actual data statuses, initiates at least one measure which, if required, ensures a safe driving operation of the motor.

Abstract
A desired-status storage device in which details concerning control devices is provided in an on-board network system and the data statuses present in each of these control devices are stored. A retrieval device addresses the control devices provided in the on-board network system and retrieves the data statuses in each case actually present in the concerned control device, and stores the result of the retrieval. A comparison device compares the data statuses stored in the desired-status storage device with the data statuses determined by the retrieval device. In the event of a deviation of the data statuses, a measures device initiates at least one measure, particularly, if required, a measure which ensures a safe driving operation of the motor vehicle.

11. A method for operating an on-board network of a motor vehicle having control devices configured to communicate with one another by way of at least one data bus, the method comprising the acts of:
-
determining which control devices are present in the on-board network and which logistics data and configuration data are stored in each of the respective control devices; addressing each control device provided in the on-board network and retrieving at least one of the logistics data and configuration data stored in the respective control devices, the retrieval preferably taking place by way of an on-board network diagnostic protocol, and the result of the retrieval being stored in the form of an actual list; checking whether each of the control devices determined to be present in the on-board network could also be addressed, and whether one or more additional control devices not previously determined to be present in the on-board network could be addressed, and whether the logistics data and configuration data for the determined control devices correspond to the addressed devices; and initiating at least one measure which ensures a safe driving operation of the motor vehicle based on said checking in the event of a deviation between at least one of the determined control devices and the addressed control devices, and the logistics data and configuration data corresponding thereto. - View Dependent Claims (12, 13, 14, 15)
