  • CAN COMMUNICATION CONTROLLER AND METHOD OF OPERATING CAN COMMUNICATION CONTROLLER
    Publication number: 20240039756
    Abstract: A CAN communication controller and a method of operating a CAN communication controller are disclosed. The CAN communication controller is for transmitting first and second types of frames wherein the first type of frame is used to transmit event-triggered communication data and the second type of frame is used to transmit best effort traffic data, the CAN communication controller configured, in response to transmitting a frame of the second type having a given identifier, to delay arbitration of a following frame of the second type having the given identifier, and not to delay arbitration of a frame of the first type.

  • Enhanced secure onboard communication for can
    Patent number: 11016926
    Abstract: According to certain general aspects, the present embodiments relate generally to securing communication between ECUs. In some embodiments, this can be done by utilizing the excess space in the CAN protocols. According to certain other aspects, security features such as sender authentication and message originality can be implemented at the protocol level, reducing the delays associated with implementing security features at higher levels in the communication stack. Additionally, the complexity of the security configuration is minimized by implementing the security features in hardware.
