CONTROL DEVICE FOR CONNECTING A CAN BUS TO A RADIO NETWORK, AND MOTOR VEHICLE HAVING SUCH A CONTROL DEVICE

摘要

A control device, which connects a CAN bus (CAN H/L) to a radio network, includes a wireless controller, a microcontroller, a CAN controller and a CAN transceiver. The CAN controller has a first channel and a second channel for transmitting (Tx) and receiving (Rx) frames. The microcontroller is connected, on the one hand, to the wireless controller and, on the other hand, to the first channel of the CAN controller. The CAN transceiver is connected, on the one hand, to the second channel of the CAN controller and, on the other hand, to the CAN bus (CAN H/L). The CAN controller is configured in such a manner that it transmits or blocks a frame received on the first channel on the basis of an identifier of the frame on the second channel. Also described is a motor vehicle having such a control device.
