On July 19, the 2012 China Automotive Electronics International Forum and Automotive Semiconductor Application Summit was held in Chengdu.
Peng Chunlin, executive director of the China Electronics Industry Standardization Technology Association, said that the automotive electronics standard system has been completed, but he did not disclose the specific release time of the standard.
User demand is the biggest driving force for the development of automotive electronics
The car of the future is a smart car based on IT. User demand is the biggest driving force for the development of automotive electronics, and IT factors have enabled disruptive innovation in the automotive industry. Taking gas as an example, how many gas stations are nearby? How about oil? What is your evaluation? Smartphones fulfill this need, but traditional cars do not have this design concept, which will cause many problems later.
In addition, intelligent transportation, driving safety and related regulations are also promoting the rapid development of automotive electronics, from manual interaction of driver transportation facilities to automatic interaction of automobile intelligent transportation facilities. Both the United States and the European Union have developed vehicle-road cooperative communication system standards, and Japan has developed VICS (Vehicle Information and Communication System).
Zhao Long, manager of BYD's automotive electronics department, believes that "users, terminals, enterprises, and industries all need higher-end automotive electronics configurations, and the better, the national policy also pays more and more attention to automotive electronics, which are the source of the development of automotive electronics."
Zou Yu, deputy director of the Automotive Technology Research Center of Chengdu University of Electronic Science and Technology, believes: "The car factory should change its mind and redesign and construct the car from the perspective of IT technology. It takes IT factors into account at the beginning of the design, instead of increasing in traditional technology Reduced. "The automotive framework based on the IT gene is shown in Figure 1.
The future development trend of automotive electronics: 1. The network is fully applied to automotive electronics, and smart cars emerged at the historic moment. 2. Car multimedia is more integrated. 3. Product features are humanized, stylish in appearance, and comfortable in experience. 4. The display equipment is integrated and develops towards the high end. This mainly refers to dot matrix instruments, LCD instruments, small TFT instruments and then large TFF screen instruments. 5. Active safety products such as night vision function, tire pressure monitoring, parking system, adaptive headlamp system, fatigue warning, etc. will become the focus of development.
Four gold mines of on-board information system
The details include: 1. Driving information service. Including dashboard information, and location, navigation, weather, traffic conditions, gas stations, special road sections and other road conditions information. 2. Security information service. Such as safety lockout, tire pressure, airbag status, accident one-key alarm, reversing video, etc. 3. Commercial information services. Merchant search, merchant booking, advertising push, etc. 4. Management information service. Including vehicle position, speed, driver information, occupant and cargo status, etc.
"Front-loaded passenger cars are now less than 1 million units, and China's own brands are about 200,000 units." Pang Chunlin introduced the front-loading market. The navigation, road conditions, and business information provided by smartphones and tablets have impacted the development of the pre-installation market to a certain extent. "No specific needs are found, and they are in a homogeneous competition with other digital terminals. Basic reasons ".
The real in-vehicle information service system has a complete upload function, high-speed calculation and feedback function, and precise control function, which are not achieved by the current system. Pang Chunlin believes that the vehicle information system market will increase at a rate of 20-35%.
In addition, Chery Chief Engineer Chen Jun said at the meeting that electric vehicle charging time and battery life are a bottleneck, and is working with Southeast University to develop wireless charging technology.
Broadcom also demonstrated 100 Mbps unshielded twisted pair in-vehicle Ethernet technology and BroadR-Reach series solutions.
