Automotive CAN bus simulation development tool Chengdu Panfeng Technology

Automobile electronic control experimental teaching system expert - Chengdu Panfeng Technology Engineer introduced: With the continuous improvement of modern automobile performance, new control functions are constantly added, such as central door locks, lighting control, glass lifting, rearview mirror adjustment, and sunroof control. , seat adjustment and ignition delay control, etc. Traditional control systems mostly use relays and independent mode control, which results in excessive wiring harnesses and complex wiring in the car, causing severe electromagnetic interference and reducing system reliability. At present, many cars use buses to connect the entire car control system for unified management, realize data sharing and mutual cooperation, make the wiring harness wiring in the car convenient and reliable, improve the overall safety and cost-effectiveness of the car, and enhance its competitiveness. . Each control unit has different response time requirements for the system. For example, the anti-lock braking system (B), drive anti-skid system (R), electronically controlled driving stability system, airbag (R), etc. have higher real-time requirements for the system. Lighting control, air conditioning control, etc. have relatively low system response time requirements.
. As there are more and more computer control units, the load of using a single network bus is getting heavier and heavier. By serving as the main controller of the system and also serving as a gateway (intelligentization of data information to be transmitted between buses) processing to ensure that only certain types of information can be transmitted between networks), control units with high real-time requirements use high-speed network transmission, and control units with relatively low real-time requirements use low-speed network transmission, which can not only improve the system's resistance to It is resistant to electromagnetic interference, and can also simplify the transmission wiring harness and improve transmission reliability.
. Based on the automotive computer control system
. 3 Function Introduction
. Select the company's positioning point 3 as the main controller and Doubles as a gateway. This type of system has a clock speed of up to The watchdog timer module is rich in resources and has convenient interfaces. It is especially suitable for situations such as automotive computer control that require high real-time and reliability requirements and serious electromagnetic interference.
. Automotive computer control systems have been widely involved in many aspects such as power, safety, environmental protection, energy saving, comfort, etc. Chengdu Panfeng Technology Engineer continued: The electronic control units () of various control systems interact with each other. Close connection requires real-time communication of large amounts of data, and public vehicle data must be shared in order to meet the real-time requirements of each subsystem. Therefore, when building a bus control system, it is always hoped that the communication control network has a higher baud rate and reliability. However, if all the nodes in the entire car are connected to a network and many nodes communicate data through a bus, it is easy for the bus load to be too large, resulting in a decrease in the system's real-time response rate. Therefore, after analyzing the real-time performance of each node in the car, a high- and low-speed communication network based on 3 was designed. The nodes with higher real-time requirements were formed into a high-speed communication network, and the nodes with relatively low real-time requirements were formed into a low-speed communication network. A gateway is set up to connect these two communication networks with different speeds to realize data sharing between all nodes. The automotive electronic control bus experimental teaching system can help develop automotive electronic control communications.
