Abstract

The invention relates to a C302-model gateway control unit characterized in that a C302 model adopts a bus structure with three CANs (Controller Area Networks) comprising a power CAN, a comfortable information CAN and an instrument diagnosis CAN, and the speeds are respectively 500K, 100K and 500K; a single gateway is designed as a route distribution center of messages and signals according to the Baud rate differences of the signals and the sharing and demands of the signals on each CAN; the route transformation is carried out on the messages with different speeds, the signals are packed and unpacked, and meanwhile, the route distribution center is also the network managing and monitoring center of each CAN bus; the time, the priority and the like of the information interaction among CAN systems are reasonably distributed; the evolution of the bus network from one CAN to a plurality of CANs and from an non-independent gateway to a central gateway is necessarily realized by a route device, and in other words, the development of the gateways is the necessary product for the updating and the function clarification of a network topology, thereby reducing the bus load rate of each subnetwork.

Description

Technical field:

[0001] The invention relates to a gateway control unit of a C302 vehicle type, which is applied to a vehicle network communication system of the C302 vehicle type. Background technique:

[0002] At present, in domestic cars, the use of independent gateways is relatively small, and it is being tested by users. FAW Car's self-owned model B131 adopts 1-channel CAN design, that is, the minimum configuration; in order to simplify the vehicle wiring harness, ensure the reliability and stability of functions, and realize the bus platform, more and more control units are added to CAN realized ranks. With the limitation of the bus load rate and signal function requirements, the multi-channel CAN system is imperative, which is also the requirement of maximizing the platform. The M6 ​​platform in production uses a non-independent gateway, that is, a control unit not only has its own control function, but also realizes the special communication function of the gateway...
