1. Policies and regulations create a considerable market for automotive sensors
After 3C smart terminals formally entered the high-speed growth stage of the market, the 4C automotive electronics’ demand for sensor introduction has also followed. Focusing on the humanitarian considerations of driving safety, governments of many countries have forced the installation of various sensor systems through laws and regulations, forming a new market created by laws and regulations.
Looking forward to the future, as the technology of driving safety assistance systems advances with the times, it is also expected to derive the potential demand for more advanced sensors, and to expand the application plan layout of the domestic ICT industry in the next stage, which will bring greater development opportunities. In view of this, this article will conduct an in-depth analysis of the development prospects of the automotive sensor technology market.
2. The number of built-in sensors in high-end cars has reached the level of one hundred
In the past, most of the built-in sensors in high-end cars in Europe, America and Japan have exceeded the level of a hundred (see Figure 1). Observing the introduction of these sensors, we mainly focus on responding to consumers’ needs for driving safety, stability, and comfort. Experts in the automotive industry once pointed out that if most of the above sensors are removed, the original operating functions of the car will not actually be affected. However, because driving is the most important personal safety, it is also driven by humane considerations. Governments around the world have successively adopted legislative procedures to form a huge legal derivative market.
In addition to the aforementioned mature markets, emerging markets such as China and India have been experiencing strong economic growth in recent years. In addition to driving the simultaneous growth of national income and living standards, local car sales are expected to exceed the scale of 18 million units in 2011 and gradually exceed the scale. Japan catches up with the United States, and has become the new focus of automotive sensor application development.
According to statistics, the market value of automotive MEMS sensors in Mainland China will grow from 3.6 billion yuan in 2008 to 6.9 billion yuan in 2011, with a CAGR of 13.9%. In addition to reflecting the gradual increase in the domestic demand market in recent years, it also highlights the region’s popularity in Europe, America and Japan. Under the generally weak demand, it played an important role in supporting the momentum of the global market in a timely manner.
In particular, the smart new energy vehicles that the Chinese mainland government intends to vigorously support through policy tools through the 12th Five-Year Plan may also drive the market demand for energy saving and carbon reduction through sensors in the near future.
As far as the product is concerned, the main functions of MEMS sensors are to perform safety detection tasks such as impact detection, tilt measurement, vibration sensing, navigation assistance, stability control, tire pressure monitoring, etc. (see Table 1), derived from accelerometer, gyroscope, pressure As the in-car network standard technology matures, the above-mentioned products have gradually integrated the concept of the Internet of Things, through the integration of multiple sensor package modules, combined sensor forms, and wireless communication technology transmission. Carrying out the process operation of active perception, intelligent judgment, and automatic control, so that driving safety can be further guaranteed.
For example, in the future, in addition to the tire pressure gauge that is mandatory for existing regulations, it is possible to further integrate inertial elements, temperature sensors, and combine with MCU and RF to form a smart sensor module, which can sense and correct tire heating at the same time. In addition to the status, the received information can also be sent to the ECU (Electronic Control Unit) wirelessly through the digital processing of the micro-controller through the analog front-end, so that it can be sensed at any time and be alerted immediately. The purpose of safety accident prevention.
The automotive image sensor system focuses on the introduction of CMOS image sensors to replace blind spots in various viewing angles to reduce the probability of collisions and accidents. Its application principles are similar to those of MEMS sensors, but the difference is that MEMS sensors focus on contact. For level sensing, CIS focuses on visual perception. Optimistic about the development potential of safe driving assistance system sensing applications, many domestic companies have recently begun to strengthen the layout of imaging subsystems such as lane departure warning, reversing photography, night vision assistance, blind spot detection, and driving record. Strengthen the overall industrial competitiveness of my country’s auto parts supply chain.
3. Conclusion
In summary, it can be known that the market demand for automotive application sensors has gradually risen. Although this market will still create demand through regulations in a government-led way at the beginning; but looking forward to the future, as mature markets continue to pursue the highest driving quality Jiahua, along with emerging markets’ greater emphasis on driving safety, is expected to gradually stimulate automakers to spontaneously increase the intellectual capacity of vehicles and gradually move towards a freely competitive commercial market.
In particular, the combined sensor products derived from the trend of multi-sensing fusion will be introduced into the market in the form of a complete solution with higher added value. For domestic industry players, accelerating the allocation of related technology research and development energy can not only take advantage of the trend to upgrade industrial technology, but also It can also increase product pricing space and accelerate profit accumulation, so that the redeployment of R&D resources can be carried out as soon as possible, forming a virtuous circle of technology R&D, and gradually promoting the transformation and upgrading of the industry.
