Abstract
The disclosure relates to a method implemented by an electronic control unit in a vehicle controller area network. The ECU has a CAN controller and a CAN transceiver that is connected to a CAN bus. The method comprises, by the CAN controller, transmitting outgoing messages and/or receiving from the CAN transceiver incoming messages that have been transmitted to the CAN transceiver through the CAN bus. Each message contains an indication of a respective level of priority among a predetermined set of levels of priority. The method comprises, by the CAN transceiver, inserting messages in at least one priority queue of a buffer, based on the indication of the respective level of priority contained in the messages and emptying the buffer at a dynamically controlled rate, following the at least one priority queue. This forms an improved solution for managing overloads of the CAN bus and/or the CAN controller.
