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 a 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 point-to-point communication connections. If we continue to use this point-to-point parallel connection method, it will inevitably lead to an increase in lines and connectors, complex wiring harnesses, and difficult wiring. Difficulties include shortage of installation space and reduced operational reliability. Therefore, in order to reduce
in-car connections, achieve data sharing and rapid exchange, and at the same time improve its reliability, modern cars adopt multi-distributed control and implement bus-based communication technology
Sharing information with each other forms 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, It meets various requirements such as safety and comfort, and needs to realize functions such as redundancy in system function design and self-diagnosis of equipment.
(rr), controller area network, is one of the most widely used open fieldbuses in the world. It is a network communication control method with advanced technology, high reliability, complete functions and reasonable cost. , B has also been widely used in automobiles. The automotive electronic network system is composed of multiple high-speed bus network communications to realize rapid interaction of vehicle power and operating system information, low-speed bus network communication to realize vehicle body operation control information interaction, and low-cost
The bus performs the necessary expansion of the network. Through the connection of the bus, multiple control networks are formed to realize mutual information interconnection, making the car more safe, reliable and intelligent, with more convenient function expansion and lighter body.
