Automotive electronic control and automotive CAN bus network experimental development system

Automobile electronic control and automobile bus network experimental development system
System Overview
With the continuous development of electronic technology and its wide application in automobile control systems, the degree of electronics in automobiles has become higher and higher. There are more and more devices. Almost every assembly on the car is an integrated device of mechanics, electronics and information. Cars are transforming from a mechanical system with a large number of electronic technologies and devices to an electronic and electrical system supported by certain mechanical devices. Traditional automotive sensors, controllers and actuators use a point-to-point communication connection method. If you continue to use this point-to-point parallel connection method, it will inevitably lead to an increase in lines and connectors, complex wiring harnesses, difficult wiring, shortage of installation space, and reliable operation. Difficulties such as decreased sexual performance. Therefore, in order to reduce in-vehicle wiring to achieve data sharing and rapid exchange, while improving its reliability, modern automobiles adopt multi-distributed control and use bus-based communication technology to share information with each other, forming the current Automotive electronic network control system, that is, in-vehicle network.
Automotive electronic control technology is an extreme manifestation of the application of electronic technology. Such as resistance to strong electromagnetic interference, adaptability to high and low temperature environments, suitable for installation in small spaces, resistance to heavy load mechanical vibration, high real-time control, reliability of operation, electromechanical and hydraulic integration technology, intelligent control strategy, environmental protection, safety and comfort. and other requirements, and need to implement functions such as redundancy in system function design and self-diagnosis of equipment.
(rr) is the controller area network, which is one of the most widely used open fieldbuses in the world. As a network communication control method with advanced technology, high reliability, complete functions and reasonable cost, B is used in automobiles It has also been widely used. The automotive electronic network system is composed of multiple high-speed bus network communications to achieve rapid interaction of vehicle power and operating system information, low-speed bus network communication to achieve vehicle body operation control information interaction, and low-cost buses to perform necessary expansion of the network. Through the connection of the bus, multiple control networks are formed to realize mutual information interconnection, making the car safer, more reliable, and smarter, with more convenient function expansion and lighter body.
