Now when people drive a car, they will find a lot of things such as: fuel consumption display, ABS, ASR, EBA, ESP, airbags, side curtain, interior temperature and humidity control, CD/DVD player, GPS navigator, electric doors and windows , electric mirrors, electric seat memory adjustment, LED lights, adaptive cruise, and many other previously used only in military, aviation, and the price is only the current level of consumer electronics automotive electronics. Electronic products currently account for 23%-30% of total vehicle costs, and they account for 50%-60% of premium luxury cars. In the future, the development of automobiles will be driven more by automotive electronics technology, and people may feel like driving a complex electronic device while driving a car. However, since the global financial crisis last year caused the decline of the entire automotive industry, many vehicle manufacturers have also put forward requirements for further reducing the cost of automotive electronics suppliers. The automotive electronics industry has grown rapidly from previous years to a period of great adjustment pressures. Strengthen cooperation between local research institutions Optimistically, the above-mentioned grim situation also means opportunities for domestic self-owned brand electronics manufacturers. The current automotive electronics sector in China is at a critical stage of improving its own research and development capabilities. Electronic manufacturers should use this opportunity to continuously increase the depth and breadth of cooperation with universities and research institutes that already have high research and development capabilities in automotive electronics technology in China. , and pay attention to more cooperation and exchanges with peers. At present, Tsinghua University, Tongji University, Shanghai Jiaotong University, Beijing Institute of Technology, Beijing University of Aeronautics and Astronautics and other colleges and universities have achieved in engine management, chassis, body control, network bus control, automotive intelligence, hybrid/electric vehicle technology, etc. High market application value results. Research institutes at all levels, including national engineering laboratories, are also focusing on the development of key technologies: engines, automatic transmissions and batteries; core actuators in various electronic control systems, such as fuel injectors, solenoid valves, VVTs, Clutches, hydraulic valves, etc. And power and electric drive systems, chassis and safety systems, body and network control systems. The development of automobile complete vehicles is based on market demand, product target customer's position, relevant laws and regulations requirements, price and other factors, to determine product design and development programs, product specifications and other design information. The automotive electronics suppliers are required to carry out the structural design and function definition of the electronic system according to the technical specifications of the vehicle design and development, and finally form the technical specifications of the electronic systems and subsystems. After being developed, tested, and tested by various automotive electronic component suppliers, they are handed over to the entire vehicle manufacturer for production. When vehicle manufacturers use synchronously developed electronic products, their suppliers must have technical reserves and previously successful products as guarantees. For vehicle development, the entire vehicle manufacturer, design company, and supporting business partners will work together to improve the functional requirements, coordinate with known products, development capabilities, time cycles, and costs, and determine the simultaneous development of supporting products. Therefore, in the establishment and improvement of independent development system, we should pay attention to the following aspects: First, develop a high-quality technical development team; Secondly, establish a complete product quality management system, have high reliability products; Third, establish a complete Hardware and software development platforms, standardized development management processes, and test equipment and methods; fourthly, often participate in high-level international technical forums and technical seminars, and actively establish contacts with international manufacturers and standards organizations to familiarize them with various Advanced standards and systems, pay close attention to the development of the international market, and constantly carry out advanced product development, forming a trapezoidal coherent R&D mechanism for current and future generations of technologies. Fifth, actively contact domestic and foreign vehicle manufacturers, and strive to seek matching opportunities with their projects and accumulate valuable engineering experience. Therefore, the development of domestic self-owned brand automotive electronics manufacturers must be supported by vehicle companies, and the planning, design, and development of automotive electronic products should be carried out under the development framework system of auto vehicle companies. Through product development, a development management system, technical team, and market-competitive products that meet the development requirements of vehicle companies are formed. At this stage, it is still relatively hopeful to obtain orders from domestic self-owned brand vehicle manufacturers. However, because they have to compete fiercely with foreign companies, the quality of the entire vehicle is under great pressure. Therefore, the quality of electronic products must be very strong. Cherish opportunities, earnestly and sincerely cooperate. In addition, the automotive electronics industry has high profits, high technology content, and has a large market development space, which may attract many electronics manufacturers. For new entrants, they must prepare enough funds, development time, and patience to obtain recognition from vehicle manufacturers. For domestic self-owned brand automotive electronics manufacturers, it is currently more suitable for the development of the following technical products: 1. Power control, throttle/direct injection engine, intelligent turbocharger, electronic valve drive, automatic transmission system, hybrid power system Wait. 2. In terms of energy efficiency and management, brake energy conversion, thermal energy conversion, electric fuel pump, LED lamp, etc. 3. Chassis electronic control: electronic steering assist system (EPS), tire pressure monitoring system (TPMS) and so on. 4.. Body Control: Power mirror control, power seat memory adjustment system, wiper control, power window control, automatic air conditioning, digital instrumentation, etc. 5. Infotainment system: GPS navigators etc. 6. Network bus control: CAN/LIN communication protocol, controller, transceiver, etc. 7. Hybrid, electric vehicles: drive motor control, power battery management system (BPMS), multi-energy management systems, DC/DC modules, etc. The following describes in detail the future of automotive electronics technology with promising development. 1.FlexRay bus Today, the drive system, body, chassis, driver assistance systems, and active/passive safety systems are all controlled by electronic systems. As the system becomes more and more complex, the in-vehicle network must not only provide faster data transmission, but also improve deterministic and fault-tolerant communication connections. Therefore, a more sophisticated control method than the CAN and LIN buses is required. The adoption of FlexRay will soon become an integral part of ensuring safety and performance, and will eventually become the primary communication channel for all safety and driving functions. This in turn reduces manufacturing costs and significantly increases the reliability of the car. Compared to the 1Mbps bandwidth of the CAN bus, FlexRay achieves 10Mbps. This technology can realize X-by-wire control and greatly improve vehicle performance. To successfully implement the FlexRay protocol on the chip requires a deep understanding of the systems they control and the applications and environments that use them. In addition, FlexRay requires very high tolerances and is suitable for linear nodes, passive star, active star, and the above network topology. Therefore, the design of FlexRay control chip and transceiver chip is quite complex and precise. . The complexity of FlexRay makes it impossible for chip companies to compete by simply integrating new IP cores on existing chips. They need to analyze the problem-solving approach more generally from an overall perspective. To achieve this goal, long-term investment in the development of standards is required, a rigorous realistic environment simulation plan needs to be established, and successful experience in the previous generation of automotive electronics technology is also required. 2. GaN device In order to reduce the cost of hybrid electric vehicles and electric vehicles, the cooling system needs to be optimized. GaN devices have high voltage resistance, high temperature resistance, high current density, fast switching speed, and low on-resistance. They are ideally suited for power circuits and motor drive circuits for hybrid electric and electric vehicles. The relevant international manufacturers are developing, and domestic developers should pay close attention to this technology. 3. MEMS technology In recent years, MEMS technology has been developing rapidly at home and abroad. The demand for MEMS from automotive electronics is also increasing, such as acceleration sensors in airbags, Yaw Rate sensors, brake system pressure sensors, and engine Manifold pressure sensors, suspension bifurcated pressure sensors, and tire pressure monitoring systems (TPMS) are all used. 4.TPMS technology TPMS includes direct and indirect, indirect TPMS has low cost, accuracy is not high enough, and direct is the opposite. The direct type TPMS installs the sensor and RF transmitter chip near the tire valve. When the tire pressure is too high, too low, rapid or slow air leakage, and abnormal temperature changes of the tire, the vehicle wireless receiver is alerted in time to effectively prevent it. A puncture. The tire pressure condition can be monitored at any time, including the spare tire, whether the car is in a running or stopped state. In order to enhance traffic safety, the United States has enacted legislation to force new production vehicles to use TPMS systems. Geely's Li Shufu proposed the "Proposed tire pressure monitoring and puncture safety mandatory standards" proposal at the two conferences in 2009. If passed, it will be a boon to the driving safety of the majority of drivers.
