Abstract

The invention relates to a motor vehicle (10) having a vehicle-internal data network (17), via which controllers (21) of the motor vehicle (10) are interconnected for exchanging messages (23). The present invention proposes that the data network (17) is divided into a plurality of security zones (25), and at least one of the controllers (21) is respectively arranged inside the security zone, and a domain control device (27) is provided, Each of these domain control means respectively separates at least two of the security areas (25) from each other, each domain control means being arranged to, when at least When a message satisfies predetermined security criteria (28), transmitting the message between at least two security zones in security zones (25) separated by domain control means, and blocking when the security criteria (28) are violated Transmission of this message (23).

Description

technical field [0001] The invention relates to a motor vehicle with a data network within the vehicle, via which controllers of the motor vehicle are interconnected for exchanging messages. The invention also includes a method for operating a vehicle-internal data network in a motor vehicle. Background technique [0002] In a motor vehicle, the controllers can be interconnected or linked via a data network, so that the controllers can exchange messages with each other. For example, measured values ​​or control commands can be communicated via such messages. The message here provides at least one data packet, which is sent by a first of the controllers, the sender, to at least one other controller, the respective recipient or receiver. A message can consist of one or more data packets. In order to transmit a corresponding message, the recipient can be specified in the message, for example by specifying the identification code and address of the receiving controller. [0...
