Controller area network (CAN) device and method for controlling CAN traffic

摘要

Embodiments of a device and method are disclosed. In an embodiment, a CAN device (300) is disclosed. The CAN device (300) includes a TXD input interface (342), a TXD output interface (320), an RXD input interface (320), an RXD output interface (340), and a traffic control system (350) connected between the TXD input and output interfaces and between the RXD input and output interfaces. The traffic control system (350) is configured to detect (352) the presence of CAN Flexible Data-rate (FD) traffic on the RXD input interface (320) and if the traffic control system detects the presence of CAN FD traffic on the RXD input interface (320), disconnect (356) the RXD input interface from the RXD output interface and disconnect (358) the TXD input interface from the TXD output interface.
