Abstract:
1. A process for networking control devices in a motor vehicle, having at least two data buses, of which first sequence-controlled control devices are connected to a first data bus and second sequence-controlled control devices are connected to a second data bus, wherein the first data bus is connected to the second data bus by at least one gateway device, the first control devices exchanging messages with the second control devices via the at least one gateway device based on a routing default, wherein the routing default comprising a routing table stored by the gateway device, the method comprising the acts of: sending a first message from a first control device of the first or second control devices via the gateway device into the at least two data buses, the first message being a message normally emitted by the first control device during operation of the motor vehicle; receiving the first message by a second control device of the first or second control devices, and checking whether the received first message is required for the second control device to carry out intended tasks of the second control device during operation of the motor vehicle; sending a response message by the second control device to the first control device indicating at least a result of said checking; and in response to the response message indicating that the first message is required for the second control device to carry out intended tasks of the second control device during operation of the motor vehicle, affecting the routing default that causes the first message, when sent again by the first control device during operation of the motor vehicle, to arrive at the second control device, and in response to the response message indicating that the first message is not required for the second control device to carry out intended tasks of the second control device during operation of the motor vehicle, affecting the routing default so that the first message, when sent again by the first control device during operation of the motor vehicle, does not arrive at the second control device.
