Controller Area Network (CAN) has been the de facto standard in the automotive industry for the past two decades, and recently CAN with flexible data-rate has been standardized, which achieves higher speed. Further improvements are possible by exploiting the peculiar physical layer of CAN to perform distributed operations among network nodes. In this paper a proposal is made for an extension to the CAN protocol, denoted CAN with eXtensible in-frame Reply (CAN XR), which enables upper protocol layers to define new custom services devoted to, e.g, network management, applicationspecific functions, and high-efficiency data transfer. Since CAN XR retains full backward compatibility with CAN FD, there is no need to change the protocol specification.

Abstract
Controller Area Network (CAN) has been the de facto standard in the automotive industry for the past two decades, and recently CAN with flexible data-rate has been standardized, which achieves higher speed. Further improvements are possible by exploiting the peculiar physical layer of CAN to perform distributed operations among network nodes. In this paper a proposal is made for an extension to the CAN protocol, denoted CAN with eXtensible in-frame Reply (CAN XR), which enables upper protocol layers to define new custom services devoted to, e.g, network management, applicationspecific functions, and high-efficiency data transfer. Since CAN XR retains full backward compatibility with CAN FD, there is no need to change the protocol specification.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
