The CAN-BUS technology profile is an abbreviation for vehicle controller networking technology integration. The explanation of CAN is-controller networking technology, including three major sections of drive system, comfort system and information system. CAN is essentially a real-time data bus and does not need to give the ground of the signal receiver
Address, the signal sender can send the securely encoded data to all receivers, the high-speed CAN bus can transmit 32 bytes of valid data every millisecond, and each signal receiver reads its own data from the bus. . Because of its strong anti-jamming capability and error correction capability, CAN technology is widely used by the US military to communicate with missile, aircraft, and tank electronic systems.
The earliest application of CAN-BUS technology in automotive communication electronic systems is Europe, which is specially equipped with high-end models. BMW 7 Series, Mercedes-Benz S Series, Audi A6 and other models are equipped with CAN-BUS system. The biggest advantage of CAN-BUS technology equipment is: reducing the number of wiring harnesses and the pins of the controller interface
Quantity, thus speeding up the transmission speed of information data and reducing transmission errors. At the same time, new functions such as online programming and online diagnosis can be realized more simply and quickly, and multiple controllers can work together. The communication nodes in CAN-BUS technology are controllers, intelligent sensors and intelligent execution units. The main function of this technology is to realize the sharing of vehicle data information with very few communication nodes.
The vehicle-wide data sharing realized by the CAN-BUS system makes the vehicle equipped with the system an intelligent whole, and thus has the ability of self-adjustment. For example, in a car equipped with CAN-BUS, when the engine is stopped, the CAN-BUS comfort system will automatically sleep.
At this time, the entire system is in the lowest power consumption state, thereby saving energy consumption. Once the door opening signal is received, without starting the engine, the system is immediately awakened and activated, and begins to receive the information transmitted by the nodes everywhere to adjust the vehicle to the best working state. The highly intelligent CAN-BUS technology is just like a savvy housekeeper, who manages the clutter of a large family in an orderly manner.
