Modern automotive electronics has entered a new stage of substantial improvement, from the electronic components used to the architecture of the in-car electronic systems. One of the most representative core devices is the smart sensor.

In recent years, my country's automobile industry has grown rapidly and has a strong momentum of development. Therefore, some experts have predicted in the commentariat that the automobile industry may surpass the IT industry and become one of the most important pillar industries of China's national economy. In fact, the growth of the automobile industry will inevitably include the growth of the IT industry related to the automobile industry. For example, although the value content of electronic products and technologies in my country's FAW products currently accounts for only about 10% to 15%, the value content of electronic products and technologies in foreign cars averages about 22%, and automotive electronics accounts for more than 30% of mid- to high-end cars, and this proportion is still growing rapidly and is expected to reach 50% soon.

Electronic information technology has become the dominant factor in the development direction of the new generation of automobiles. The improvement and improvement of various aspects such as power performance, control performance, safety performance and comfort performance of automobiles (motor vehicles) will rely on the perfect combination of mechanical systems and structures, electronic products and information technology. Experts in the automotive engineering community pointed out that the development of electronic technology has brought about profound changes in the concept of automotive products. This is one of the reasons why the electronic information industry has recently paid unprecedented attention to automotive electronics.

However, it must be pointed out that, except for some in-car audio and video equipment, in-vehicle communication and navigation systems, as well as in-vehicle office systems, network systems and other in-vehicle electronic equipment that have changed less in nature, modern automotive electronics has entered a new stage of substantial improvement from the applied electronic components (including sensors, actuators, microcircuits, etc.) to the architecture of in-vehicle electronic systems. One of the most representative core devices is smart sensors (smart actuators, smart transmitters).
