Intelligent driving domain controller, you can simply understand the intelligent driving domain controller as the brain of the intelligent driving car.
It is mainly responsible for the fusion, identification, classification of the perceived information, and then planning and decision-making of the vehicle, and finally to complete the precise control of the vehicle, so as to achieve the purpose of intelligent and safe driving of the vehicle.
At the software level, domain controller has system layer, middleware, application layer algorithm and so on.
At the hardware level, there are often three, or groups of chips, on a domain controller.
The first chip has a very large computing power, usually GPU or TPU, mainly for the fusion, identification, classification of perceptual information, etc. This chip is good at large-scale low-precision floating-point operations, and also bears most of the computing power needs of the domain controller.
The second chip is an ARM, which is mainly an integrated system and performs logic operations such as planning and decision-making at the same time. It is generally good at high-precision floating point string operations. This chip is very similar to the CPU processor we are familiar with.
The third chip is often a high-reliability MUC, mainly responsible for vehicle control, this chip is characterized by high reliability, but the computing power can be not so large, generally to ASIL-D.
It's a car chip.
MUC is an automotive microcontrol unit chip.
It is the largest chip gap of all cars, \"take Volkswagen Golf as an example, there are about 70 controllers, each controller needs to use MCU chip, smart car is double\
Renesas Electronics, the world's third largest manufacturer of automotive chips, suffered a serious fire in March, coupled with the impact of the previous epidemic, which is now showing a total outbreak trend, may lead to 4 million vehicle production capacity affected.
In the current chip supply is tight, many car companies have to adjust production plans.
