So, is this little "car chip" really so important to a car? In fact, to put it simply, a car chip is equivalent to our human "brain" for a car, which controls almost all "behaviors" of the entire car.
Especially now that cars are moving towards the era of intelligence, autonomous driving, digitalization and electrification, with the introduction of deep learning algorithms, the amount of data processing is increasing, and automotive chips have become particularly important for a car.
To give a simple example, everyone knows about tire pressure monitoring, but if you want to realize this function of the vehicle, you need a separate chip to support it to complete this monitoring task.
So now even an ordinary car has more than 40 chips, let alone those pure electric cars or cars with automatic driving functions.
Some ultra-luxury models have hundreds of chips. If there is a shortage of one chip, the production of the entire car will be affected.
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.
1. Functional chip
MCU is also called "micro control unit". If the electronic control system, infotainment system, powertrain system, vehicle motion system and other system functions in the car want to run normally, they need to use this type of functional chip. Among them, the most popular "automatic driving system" is also inseparable from functional chips.
2. Power semiconductor
Power semiconductors are mainly used in automotive power control systems, lighting systems, fuel injection, chassis safety and other systems. Traditional fuel vehicles generally use them in the fields of starting, power generation, and safety; new energy vehicles require a large number of power semiconductors to realize vehicle Frequent voltage conversion requirements, and the blessing of power semiconductors are also indispensable in many parts of electric vehicles.
The automotive sensor is the input device of the automotive computer system. Its function is to convert the information of various working conditions in the running of the car, such as the speed of the vehicle, the temperature of various media, the operating conditions of the engine, etc., into electrical signals and send them to the computer. best working condition. Such as oxygen sensor, tire pressure sensor, water temperature sensor, electronic accelerator pedal position sensor and so on.
The service attitude is not bad, a satisfactory cooperation.
Personally, I think it is very good, and the proposal proposed is very suitable and will continue to cooperate.
Shipping was fast, very good.
After seeing this strength, we will always cooperate as the first choice.
Cars and vehicles are becoming smarter and smarter thanks to automotive chips. There are 3 types of automotive chips:Micro control unit (MCU).Automotive power chips.Automotive chips for sensors.
-High standards -Long lifespan -Wide operating temperature range -Excellent resistance to harsh environments -Quality consistency
A traditional car needs 500 to 600 automotive chips. An electric car needs about 2,000 automotive chips as it has a large amount of DC-AC inverters, transformers, converters, and these modules lead to an increase of IGBT, MOSFET, diodes and on in a car.
