System overview
With the continuous development of electronic technology and The wide application in automobile control systems has made automobiles more and more electronic and there are more and more electronic 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-car connections to achieve data sharing and rapid exchange, while improving its reliability, modern automobiles adopt multi-C distributed control and use C-bus-based communication technology to share information with each other, forming a The current automotive electronic network control system, that is, the 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.
C stands for 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, CB has also been used in automobiles. Has been widely used. The automotive electronic network system is composed of multiple Cs using high-speed C-bus network communication to realize rapid interaction of vehicle power and operating system information, low-speed C-bus network communication to realize vehicle body operation control information interaction, and low-cost buses to perform necessary tasks on the C network. expansion. Through the connection of the bus, multiple Cs are formed into a control network to realize mutual information interconnection, making the car safer, more reliable, and smarter, with more convenient function expansion and lighter body.
