Automotive sensor market size, the current domestic domestic car on a typical installation of dozens or even hundreds of sensors, luxury cars sometimes use hundreds of sensors. The sensor is the 'probe' of the electronic control system, known as the car's brain and five eyes. Vehicle operating status, driving control status, vehicle control, operating environment, abnormal status Sensor and other information are obtained through the sensor. The number of sensors and technical level determines the level of the car control system level, it uses more, the electronic car, the higher the degree of automation. With the electronic automotive, intelligent development, the future application of automotive sensors will also increase.
Automotive sensor applications From a global perspective, the fastest growing sensor market is the automotive market. At present, sensors are widely used in tires, airbags, chassis systems, engines, operation management systems, exhaust and air quality control systems, vehicle safety systems, automotive anti-theft systems, engine combustion control systems, automotive positioning systems and other products.
Automotive installation of the sensor has three purposes: First, safe, such as air defense airbag safety monitoring; Second, energy saving, reduce environmental pollution; third is comfortable.
With the increasing popularity of automotive safety applications and the reduction of carbon emissions, the penetration of sensors in the automotive electronics sector is increasing, and new technologies such as unmanned driving today are driving the adoption of advanced sensors. In each car, the light TPMS system will use 4.2 automotive MEMS sensors, China has now surpassed fuel metering valve Japan to become the third largest automotive MEMS market.
Common sensors on the car are accelerometers, gyroscopes, electronic compass, barometer, infrared sensors, ultrasonic sensors, laser range finder, radar sensors.
China's automotive sensor competitive landscape At present, China's 90% of the automotive sensor market by the mainland, Bosch, Delphi, Sentazar, Honeywell and several other foreign-funded enterprises monopoly. Domestic vehicle sensor business can only do oil temperature sensor, water temperature sensor and other technical content is not high, the value of relatively low sensor. China's flow sensors, pressure sensors, temperature sensors and horizontal sensors on the technology has matured, some companies have begun to foreign-funded enterprises on behalf of the processing, such as Hefei Bangli Electronics to Bosch ABS matching sensor.
At present, radar, ABS and so on more and more to become the vehicle before the company's products, this type of sensor demand rose rapidly. In addition, the continuous improvement of vehicle emission standards, to the mainland, Bosch, Delphi, Denso and other foreign parts and components enterprises to bring a monopoly position. For example, in the engine operation and management system and the exhaust gas and air quality control system in the application of sensors, materials and technology requirements are more stringent, the mainland developed a nitrogen oxygen sensor to quickly monopolize the market. Continental nitrogen sensor has a patented technology, just to catch up with China's auto emissions upgrade, all diesel vehicles need to install this sensor, this sensor market share is 100%.
At present, China's automotive sensor industry is facing a major opportunity for development. With the increasing popularity of automotive safety applications and the reduction of carbon emissions, especially the introduction of new energy vehicles, unmanned and other emerging technologies also promote the further popularization of advanced sensors, not only the number of sensors to expand, in the sensor type and parameters Indicators have to further expand and enhance. Although foreign enterprises in the capital, technology and other aspects Temperature Sensor of a strong competitive advantage, but the domestic market space is vast, home operations of local enterprises have inherent advantages and disadvantages, you can quickly make up for changes in market changes, there are still many opportunities for survival and development And space.
China is a big supplier of automotive sensors, but 90% of the automotive sensor market by the mainland, Bosch, Delphi, Sen Sata, Honeywell and several other foreign-funded enterprises monopoly, the domestic automotive sensor industry is facing many challenges.
1. Foreign core patent monopoly: Automotive sensor core patents are mostly monopolized by foreign manufacturers, a serious impediment to the development of China's independent sensor products. China's independent research and development of the sensor technology to enhance the need for domestic manufacturers to increase core technology research.
2. Low level of technology: domestic automotive sensor production began in the last century 80's, because the start time later, despite the continuous progress in recent years, but whether in technical quality, production capacity or production scale and international advanced technology compared to the gap Are relatively large. The vast majority of enterprises are still in a small profit, product single, low level of technology, poor reliability of the situation.
3. Materials and processes: Many domestic independent sensor company's raw materials need to be imported from abroad. Although the sensor principle is not difficult, not confidential, but the most critical part of the process is confidential.
The breakthrough of domestic enterprises
1. Strategic planning of industrial chain
As the sensor industry across multiple areas, belonging to different industries and departmental management, resulting in industrial management is too scattered, the lack of a unified coordination mechanism. Therefore, for automotive sensors, the need to develop a unified industrial development of long-term strategic planning, the introduction of a continuation Suction Control Valve of the industrial development policies to promote the upgrading of industrial collaboration and innovation.
2. Increase R \u0026 D investment
Foreign auto sensor giants have always attached importance to R \u0026 D investment, Bosch 40 years ago began to develop automotive sensors, Honeywell annual out of 18% of research and development costs to research and development, etc., these enterprises in the automotive sensor several major applications have their own expertise , In a certain area of monopoly.
At present, China's automotive sensor R \u0026 D investment less, leading enterprises can not grasp the core technology, new products obviously insufficient, high-tech products less, digital, intelligent, micro-products seriously lack. Automotive sensor research and development need a lot of money and time, too many varieties, the government needs to re-positioning of automotive sensors, and establish development goals, combined with industry characteristics of the top design, to carry out systematic and scientific research.
3. value win
Domestic auto sensor manufacturers do not increase production, the cost down not down, and the car OEMs difficult to contact. Similar products, the domestic manufacturers used to 'win at low prices' to capture the market, but in the automotive sensor industry has long been impracticable. With the importance of foreign enterprises to improve the price, making the price gap between similar Pressure Sensor products gradually smaller. Automotive OEMs are more willing to choose the reliability of strong, high-level foreign products. Some of the days of domestic sensor manufacturers are increasingly sad. Therefore, China's auto sensor manufacturers to improve their efforts in the technology, only technological breakthroughs to win the value in order to occupy the dominant competition in the future.
China's automotive sensors are facing a difficult road, but it is foreseeable that the future of China will affect the global automotive sensor market, a key role in changing the current international Throttle Position Sensor giants carved up the market competition, the Chinese automotive sensor to write a new chapter.
