Control LAN () belongs to the industrial field bus, which was used by a German company in the early 1900s to solve the problem between numerous control and test instruments in modern automobiles. A communication protocol developed for data exchange. An engineer from the Automotive Bus Experimental Teaching System R&D Company introduced in 2011: The international standard for high-speed communication ( ) was officially promulgated. In the bus system, the collection of field data is completed by sensors. Currently, the types of sensors with bus interfaces are Not much and more expensive.
Principle and structure of wire-controlled electronic throttle system Automobile bus experimental teaching system
Electronic throttle control technology first appeared in the early 1990s and was initially only used in high-end cars. With the increasing development of electronic technology, energy issues and With the increasingly prominent environmental issues and the increasing requirements for vehicle performance, electronic throttles have become the most important control device on fully electronically controlled engines and have begun to be widely used in various vehicles. Its advantage is that it can be adjusted according to the driver's wishes, emissions, fuel consumption and safety. The demand is to quickly and accurately control the throttle valve at the optimal opening, and to set a variety of control functions to improve driving safety and comfort. Currently, companies such as Toyota are researching this technology, and manufacturers such as General Motors Toyota D are using it on some of their models. has been successfully applied.

There are a large number of sensors, electronic control units, actuators, etc. in the vehicle control system. Usually multiple controllers share the same sensor information and are real-time and fast. The requirements are high. How to connect them to form a distributed control network system is an important development direction of modern control systems. Fieldbus control system ( ) is one of the typical control network structures. The implementation belongs to the category of fieldbus. It is a Multi-master serial buses that effectively support distributed control or real-time control are favored for field device interconnection due to their short message frames and excellent bit-by-bit arbitration protocols.
The bus-based vehicle distributed control network system as shown in the figure adopts a fieldbus distributed system (D) structure, which is composed of sensors, actuators, controller intelligent nodes and field control networks. Multiple intelligent nodes independently complete data. Collection, system setting, operation control, etc. exchange various data and management control information between intelligent nodes through the field bus.
