Divided by function, automotive chips can be roughly 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 electronic control units for engine, chassis, and body control. The second type is responsible for power conversion, such as power devices such as insulated gate bipolar transistors, and the third type is sensor chips, which are used for automatic driving, various radars, and airbag tire pressure detection. According to estimates, each car is equipped with about 1,600 semiconductors on average. These semiconductor devices are distributed in various equipment and systems of the car. It is the car chip that dominates their collaborative work, such as logic computing chips, memory chips, and microcontrollers. Cars are inseparable from various chips, ranging from tire pressure detection, system cameras, to vehicle controllers, automatic driving and controllers. It can be said that the intelligence of the car is the intelligence of the chip.
