Description of automobile chip assembly:
1. Function chip (MCU)
MCU is also called "micro control unit". If the functions of electronic control system, infotainment system, powertrain system, vehicle motion system and other systems in the car want to operate normally, this type of function chip is required to achieve it. Among them, the most popular "auto drive system" is also inseparable from the function chip.
2. Power semiconductor
Power semiconductor is mainly used in automobile power control system, lighting system, fuel injection, chassis safety and other systems, among which traditional fuel vehicles generally use it in the fields of starting, power generation, safety and so on; New energy vehicles need a large number of power semiconductors to achieve the frequent voltage conversion needs of vehicles. In addition, many parts of electric vehicles also need the support of power semiconductors.
3. Sensor
The automobile sensor is the input device of the automobile computer system. Its function is to convert various working condition information during the automobile operation, such as vehicle speed, temperature of various media, engine operating condition, etc., into electrical signals and send them to the computer, so that the automobile is in the best working condition. For example, oxygen sensor, tire pressure sensor, water temperature sensor, electronic accelerator pedal position sensor, etc.
So to sum up, car chips are very important for a car. Among the three types of function chips, power semiconductors and sensors, sensors have the smallest market share. But if there is no sensor, cars can't even step on the accelerator. Now I believe we all understand why cars can't be built without chips.
How many chips does a car need?
In the past, it used to take about 500-600 chips to make a traditional car. But with the continuous development of the automobile industry, today's cars are gradually turning from mechanical to electronic. Cars are becoming more and more intelligent, so the number of chips required will naturally be more. It is understood that the average number of chips required for each car in 2021 has reached more than 1000.
In addition to traditional cars, new energy vehicles are the "big family" of chips. Such vehicles need a large number of DC-AC inverters, transformers, converters and other components, and the demand for IGBT, MOSFET, diodes and other semiconductor devices has also increased significantly. Therefore, a better new energy vehicle may require about 2000 chips, which is very surprising.
