At present, China's automobile industry is stepping into the 'new four modernizations' era represented by ADAS & autonomy, connected, electrified and shared services. According to the data of IHS Markit, by 2023, the total amount of automotive electronic systems will be as high as 180 billion US dollars, with an average of more than 500 US dollars of semiconductor devices used in each vehicle. The applications with great increase are from advanced driving assistance system (ADAS), power train and on-board entertainment information system (infotainment). Among them, ADAS ranked first with an increase of 23.6%.

The reason for the rapid growth of ADAS, on the one hand, stems from the fact that automobile manufacturers are committed to improving the safety of vehicles and constantly developing new technologies to help reduce road accidents and ensure the safety of internal connections. In the past few years, it has realized the high-speed。

On the other hand, transportation regulators all over the world, including China, have raised the evaluation standards in their own safety regulations and requirements, and all vehicles must comply with them. All these clearly indicate that China is paying more and more attention to the active safety function of ADAS.

The driving force behind the 'qualitative leap' is inseparable from the complex software and hardware processing ability, which is the rapid promotion of fault protection engineering design to become one of the important standards in today's automobile industry. Automotive semiconductor suppliers such as microchip have been committed to providing a wealth of MCU and automotive networking solutions to meet the automotive functional safety requirements of iso-26262 standard.
