Abstract


With the development of modern automotive technology , automotive electronics equipment , vehicle control system will generate a lot of information needs to be exchanged in real time , while the traditional point-to-point wiring must exist between the automotive electrical wiring complexity , maintenance difficulties and difficult to achieve real-time exchange of signals . In this context the automotive LAN emerged ; CAN bus has the advantages of simple structure, high reliability, the technology is mature , as car a serial bus is widely used in the automotive sector . In this paper, a comparative overview and analysis of the car field bus type , pointed out that the the mainstream advantage of CAN bus in the field of automotive electronic control . The basic principle of the CAN bus analysis , and messaging , packet filtering , packet checksum , coding detailed introduction . As the basis for body electrical control system to make optimized design . The main method is to transform the existing body electrical system on the body nodes are classified in accordance with the different categories of functions and power devices , and subsequently on various nodes in accordance with optimal control to improve the functionality of the design concept design . In terms of hardware components re-optimize the selection , deletion or increase the element nodes more beautiful and practical function better ; improve the software aspects of the original program , and add a new plus-function program , more reliable communication . Finally, the experimental method to verify the feasibility of the method . The main achievements of the topics : 1. Existing CAN test bench has been improved to more fully demonstrate the superiority of the CAN bus . Re nodes classification, and press components selected categories of various node interface circuit part optimization , to further improve the appearance and functionality of the node . 3 . Optimize the CAN bus data transfer with the host computer , whether it is a PC or laptop can be convenient to communicate with the CAN bus . The design for the university's teaching laboratory equipment , but also the basic idea is to provide for the general development of the CAN bus .
