Data processing method and device based on MCU communication path, equipment and medium

The invention discloses a data processing method and device based on an MCU communication path, equipment and a medium. The method comprises the steps that a CAN data set corresponding to a current vehicle is acquired through a vehicle CAN bus; the CAN data set at least comprises vehicle data and environment data; transmitting the obtained CAN data set to a vehicle micro-control unit through a CAN interface, and accessing the CAN data set to an application layer of the vehicle micro-control unit; transmitting the CAN data set to an Ethernet interface through a CAN interface; and the CAN data set is sent to a vehicle micro-control unit through an Ethernet interface, and communication data of the Ethernet interface is accessed to an application layer of the vehicle micro-control unit. According to the invention, the CCS and the vehicle control node which are deployed on the Host are used as two SWCs to run on the MCU application layer and are in butt joint with the bottom input/output interface so as to realize
