System overview of automobile electronic control and automobile bus network experimental development system
With the continuous development of electronic technology and its wide application in automobile control systems, automobiles are becoming 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. The traditional point-to-point communication connection method between automotive sensors, controllers and actuators will inevitably lead to an increase in lines and joints, complex wiring harnesses, difficulty in wiring, shortage of installation space, and operational reliability if this point-to-point parallel connection method is continued. Reduce difficulties. Therefore, in order to reduce in-vehicle wiring, realize data sharing and rapid exchange, and improve its reliability, modern automobiles adopt multi-distributed control and bus-based communication technology to realize mutual information sharing, forming the current automotive electronic network control. The system 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.
() That is, the controller area network 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, it has also been widely used in automobiles. Applications. 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 interconnected and interconnected, making the car safer, more reliable, and the expansion of intelligent functions more convenient and lighter.
