Panfeng Technology analyzes the structure of automobile body network system

Nowadays, the number of cars is increasing and they are one of the very important means of transportation in today's society. However, with the continuous development of emerging technologies, especially the widespread application of computer technology, electronic control technology, artificial intelligence and network communication technology in automobiles, necessary conditions have been created for the electronic development of automobiles. Of course, the automobile industry is also a major pillar of the national economy. The widespread application of electronic technology in automobiles is one of the important signs of the development of today's automobile industry. Chengdu Panfeng Technology introduces to you the structure of the body network system
As we all know, with the continuous development of the automobile industry and the increasing number of automobiles, countries around the world are facing serious automobile emission pollution and energy crisis. and issues such as vehicle driving safety. Faced with these practical problems, traditional automotive technology can no longer solve them. At the same time, countries around the world have introduced corresponding regulations to address the above issues, forcing the automotive industry worldwide to carry out technological innovations. Automotive electronics and automotive bus technology are constantly developing, and the demand for such technical talents will continue to increase. In order to solve the pollution, energy saving, and safety problems of automobiles, electronic control technologies are widely used in automobiles, such as electronically controlled fuel injection systems, electronically controlled automatic transmission systems, and B. Many new products are emerging one after another, and as people pay more attention to automobile comfort and intelligence With the continuous pursuit of globalization, electronic control technology will bring epoch-making changes to the automobile industry.
Overall structural design of vehicle management system
The sensitivity of various electrical appliances in automobiles to network information transmission delays is very different, such as engine controllers, automatic transmission controllers, B controllers, airbag controllers, etc. The coordination relationship between them requires strong real-time performance, while simple events such as front and rear light switches, door opening and closing, and seat adjustment have much looser information transmission delay requirements (transmission delay allowance mm). If these functions are combined Simple nodes are all hung on the high-speed bus, which will inevitably increase the technical requirements and costs of the nodes. Therefore, it is necessary to carry out multi-channel bus design. Taking into account the consistency with international standards, a single bus is used here
In automotive drive systems Using high speed, the information transmission speed reaches b, and its main connection objects are: engine, automatic transmission, R, airbag, active suspension, cruise system, electric steering system and combination instrument signal acquisition system and other drive system control objects are all The industrial automation network of systems directly related to automobile driving control has strong real-time requirements for signal transmission. There is a lot of information exchange between them, and many of them are continuous and high-speed.
The structure of the automobile body network system is based on the bus, integrating convenience and safety, making today's cars more and more electronic. Chengdu Panfeng Technology Co., Ltd. is committed to automotive electronics and automotive bus network experimental development systems, and has professionally developed instrument cluster test boxes, Shuang gateway test boxes, door control test boxes, car light control test boxes, smart sunroof test boxes, and anti-theft alarm experiments. box, reversing radar experimental box, not only that, we also team the vehicle B network and its related development.
Chengdu Panfeng Technology is committed to the experimental development of automotive electronics and bus networks, and practical training and teaching equipment. It independently develops and provides product schematics and source programs for secondary development. Can simulate, record, simulate and send communication information!
