Inventory of the main application areas of automotive chips

The main control chip is used to generate the calculation and generation functions of the main control signals of the car. The main control chip receives the signals collected by various sensors, calculates the corresponding processing measures, and sends the drive signal to the corresponding control module. Therefore, the main control chip is equivalent to the "brain" of the car.

Power chips are the part with the largest increase in value in new energy vehicles. The demand side is mainly for products such as IGBT, MOSFET and IPM modules integrating multiple IGBTs, and the core is used in high current and high voltage environments.

CMOS chip is a chip that converts photons into electrons for digital processing and image signals into digital signals. It includes microlenses, photodiodes, processing chips and IO interfaces, and is a key component of the camera. As the level of autonomous driving increases, it is estimated that assisted driving above L3 will require about 18 cameras, mainly used in the fields of reversing rear view, surround view, front view, and turning blind spots.

RF receivers are important components of wireless communications. RF chips refer to chips that can convert RF signals into digital signals. They include power amplifiers PA, filters, low noise amplifiers LNA, antenna switches, duplexers, tuners, etc. In the future, RF chips will help the development of C-V2X technology like the ears of cars, organically linking traffic participation elements such as "people-car-road-cloud", making up for the lack of single-car intelligence and promoting the development of collaborative application services.

Ultrasonic/millimeter wave/lidar are sensors for sensing the vehicle body. Smart cars obtain a large amount of data through sensors. L5-level cars will carry more than 20 sensors. Vehicle-mounted radars mainly include ultrasonic radar, millimeter wave radar and lidar. Among them, China's ultrasonic radar has developed relatively maturely and has low technical barriers; millimeter wave radar has high technical barriers and is an important sensor for smart cars. It is currently in a stage of rapid development; lidar has high technical barriers and is an important sensor for high-level autonomous driving, but it is currently expensive, difficult to pass vehicle regulations, and difficult to implement.

Storage chips are the "memory" of smart cars. The upgrade of autonomous driving technology will bring about a long-term trend of continued high growth in the bandwidth of automotive storage. In the future, automotive storage will move from GB level to TB level.

The automotive panel is showing a trend of multi-screen. The acceleration of automobile intelligence and electrification will drive the number of panels per car, and the in-vehicle panels are also beginning to move towards standardization. From the demand point of view, the application of display screens in automobiles is becoming more and more extensive, and the demand is growing strongly. In-vehicle displays mainly include central control display screens, instrument display screens, windshield composite head-up display screens, virtual electronic rearview mirror display screens, rear seat entertainment display screens, etc. With the promotion of factors such as the Internet of Vehicles, new energy vehicles, and unmanned driving, people's demand for in-vehicle panels with functions such as navigation, vehicle status, and multimedia audio and video will continue to expand.
