Automotive chips can be broadly divided into three categories: the first category is responsible for computing power and processing, such as AI chips for autonomous driving perception and fusion, and traditional MCUS for engine\/chassis\/body control; The second type is responsible for power conversion, such as IGBT and other power devices; The third category is the sensor chip, which is used for automatic driving various radars, as well as air bags, tire pressure detection and so on.

The production and manufacture of a traditional car generally must use 500-600 chips, with the continuous development of the automotive field, the car slowly from the pedal type to the electronic orientation development, the car is becoming more and more intelligent, then the number of chips required is of course more and more. The average number of chips required for each car in 2021 has already reached more than 1,000.

In addition to traditional vehicles, new energy technology vehicles are chip \"planters\

The number of chips for fuel vehicles is about 500 to 600, and the number of chips for new energy vehicles is about 1000 to 1200. The instrument in front of the steering wheel, the central control screen, the autopilot system these needless to say without the chip basically can not play! As small as remote control keys, car radios, sensor wipers, automatic headlights, to complex unmanned systems, all need chips to control, and even more than one. The average car is equipped with about 1600 semiconductor devices, these semiconductor devices are distributed in the various equipment and systems of the car, leading them to work together is the car chip, such as logic computing chip, memory chip, microcontroller MCU and so on.
Automotive chips are mainly car level chips, divided into functional chips, IGBT chips, MOS tubes, sensors and others.
