Abstract

The invention relates to a common platform system of a vehicle-mounted electronic processing unit and a data communication method of the common platform system. In the system, function expansion modules constitute a real-time Ethernet or a CAN network. The basic system mainly comprises a main control panel which is provided with a central processing unit, the central processing unit is connected with the function expansion modules of the real-time Ethernet through Ethernet modules, and the central processing unit is connected with the function expansion modules of the CAN network through CAN bus modules. The main control panel and all the function expansion modules achieve data communications based on a real-time Ethernet application layer protocol format or a CAN network application layer protocol format, and a communication receiver obtains data and analyzes the data according to the real-time Ethernet application layer protocol format or the CAN network application layer protocol format. According to the common platform system of the vehicle-mounted electronic processing unit and the data communication method of the common platform system, data sharing and resource sharing are achieved among all the function modules, and the technical problem that increasing or decreasing or replacing or new module adding of the function expansion modules is difficult to achieve due to the fact that a uniform physical interface and a communication protocol do not exist in the prior art is solved.

Description

technical field

[0001] The invention relates to vehicle-mounted electronic processing unit technology, in particular to an open and expandable vehicle-mounted electronic processing unit public platform system and a data communication method thereof. Background technique

[0002] The rapid development of automotive electronics technology has greatly improved the performance of the interior of the car. The most representative is the electronic control unit ECU (Electronic Control Unit), which is composed of integrated circuits to realize the analysis, processing and sending of data, etc. A series of functional control devices are currently widely used in automobiles, and the integration level is getting higher and higher. On the other hand, the development of automotive electronic technology has also led to the emergence of vehicle-mounted products such as GPS navigators, driving recorders, audio-visual systems, reversing sensors, and central locks. It ensures the comfort, sa...
