The automobile intelligent body central electrical control system is a new control component product in the field of automotive electronics and is included in the national and Shanghai City high-tech industrialization guidelines catalog.
This project uses computer, large-scale integrated circuit, intelligent power semiconductor and vehicle CAN bus control technology to design the body controller (BCM) and the central electrical box (BEC). From the perspective of saving energy consumption, reducing costs and facilitating vehicle assembly and maintenance, the two independent assemblies of the vehicle BCM and the central electrical box BEC are integrated and designed into one. It has developed an automotive intelligent central electrical control system with high reliability CAN bus technology, and innovated in China to form a new generation of intelligent body electronic control system (E-BOX) architecture products. Breaking the bottleneck of complex wiring harness connection between the two. It realizes network control of body electronics, intelligent distribution of strong and weak current, intelligent fault diagnosis and alarm, data communication and control coordination and other functions, effectively solving the complexity of connecting wiring harnesses after the increase of automotive electronic control devices and the reliability of complete closed-loop control of system products. Sex problem. The products of this system have been searched and searched by the Shanghai Institute of Science and Technology Information and have reached the international advanced level.
As one of the top ten companies in the automotive electronic and electrical parts industry of China Automobile Manufacturers Association, the company follows the development trend of international intelligent body control system technology and establishes an automotive electronics joint laboratory with Shanghai University to carry out the research and development and industrialization of intelligent body control systems.
The key technologies solved by this project's product are: 1. Electromagnetic interference to the CAN-bus body controller caused by the large current of the electrical box and the attraction of relay contacts after the system is integrated and connected;2. Synchronous processing of bit timing of the CAN controller;3. Method to realize a multi-message mechanism in the CAN controller;4. A low-power remote control and receiving, bus communication and diagnosis structure for the CAN-bus body controller.
The products of this system have obtained three authorized invention patents, obtained Shanghai City Patented New Products, Key New Products, and Famous Brand Product Certificates, and passed the recognition of the Shanghai City High-tech Achievements Transformation Project. Many research papers were included in EI and SCI. In 2008, this system product was successfully used by Shanghai Intiac Auto Parts Company for taxis for the Beijing and London Paralympics. In 2010, it was equipped with FAW-Volkswagen Jetta's new platform vehicle. Since 2011, intelligent CAN bus products have been approved and used by SAIC Group's Nanjing Iveco new model. A total of 325,000 units were produced, with an output value of 91.12 million yuan and profits and taxes of 12.72 million yuan. This project is the first time in China that it supports FAW-Volkswagen Jetta and SAIC Nanjing IVECO. It breaks the technical monopoly and product supporting monopoly of major international companies in the field of bus body control, enhances the company's influence in the domestic and foreign automotive electronics fields, and obtains good economic and social benefits.
