Title: MOTOR VEHICLE COMPRISING AN INTERNAL DATA NETWORK AND METHOD FOR OPERATING THE MOTOR VEHICLE
Abstract:
The invention relates to a motor vehicle (10) comprising a vehicle-internal data network (17), by means of which control units (21) of the motor vehicle (10) are interconnected in order to exchange messages (23). According to the invention, the data network (17) is divided into a plurality of security zones (25), in each of which at least one of the control units (21) is arranged and domain control devices (27) are provided, each of which separates at least two of the security zones (25) from one another and is designed to transfer at least one of the messages (23) between at least two of the security zones (25) separated thereby if the message (23) satisfies a predetermined security criterion (28), and to block the transfer of the message (23) if the security criterion (28) is not satisfied.
