The introduction of the policy has prompted the smart car field to gradually become a new battlefield between OEMs, component suppliers and Internet companies. Then, as an upstream semiconductor manufacturer, how do you view the smart car market, what programs have been introduced in the automotive field? Let's take a look at the latest views of TI, ON Semiconductor, NXP, and Renesas Electronics.
TI: Multi-core heterogeneous architecture SOC storms the ADAS market
From the initial semiconductor component semiconductorization, to the car entertainment navigation and the rapid development of ADAS, the proportion of automotive electronics in the whole vehicle is gradually increasing, and the added value of semiconductor products for automobiles has greatly improved the driving of automobiles. The experience also drives the future of the car towards smarter and safer. More and more cars are beginning to adopt driver assistance systems and continue to evolve toward driverless driving.
Jiang Hong, director of embedded product systems and applications in Texas Instruments, pointed out that the mainstream trend of ADAS is: camera and radar system as the main body, combined with the integration of various sensors (night vision, laser radar, ultrasonic, etc., coupled with high-precision positioning Integration with navigation systems, as well as cars and cars, cars and infrastructure.
Furthermore, TI's ADAS processor is a typical multi-core heterogeneous architecture. Its multi-core C66x DSP and multi-core EVE composite main processing unit can easily complete real-time tasks that cannot be achieved by the current multi-core PC architecture. At the same time, it also has extremely low power consumption, and there are multiple MCU microcontrollers inside the chip. It assists in handling various tasks such as scheduling inside the chip and response of the chip input and output interface.
The chip also has all the necessary hardware acceleration, as well as a rich input and output interface. At present, mainstream ADAS equipment suppliers basically use TI's ADAS chips. TDA2x and TDA3x chips are rapidly entering the Chinese market, and it is believed that more and more ADAS equipment suppliers will use TI's ADAS chips. Below are three examples of automotive applications based on the ADAS chip.
ON Semiconductor: Image sensing technology guarantees car safety
Wu Zhimin, director of application engineering at ON Semiconductor China, said that in order to cope with the increasingly fierce competition in technology and products, ON Semiconductor did not meet the existing market share and product range, but responded to the development and changes of the situation, proactively attacked and expanded. Improve the automotive electronics product line, especially in various sensors and power devices, and strive to provide customers with one-stop products and services, including proprietary automotive solution engineering centers, design, system architecture and field application engineers.
At present, the electronic function rate of automobile is about 15%, and the cost accounts for about 20% of the cost of the whole vehicle. It has changed from a simple mechanical product to a complex mechatronic product. An important symbol of a car becoming a mechatronic product is The actuator is gradually driven by the motor.
Wu Zhimin pointed out that in order to meet the requirements of consumers for power, comfort and convenience, and even energy saving and environmental protection, there are more and more motors for vehicles, and they are moving from DC brush to DC brushless. Automotive electronic semiconductor chips must be able to implement more complex functions, such as various ASSPs and SoC chips for applications, with the ability to actively monitor faults, work in harsher environments, and have higher reliability.
As the number one supplier of automotive image sensors, ON Semiconductor continues to innovate and invest in next-generation automotive solutions, including breakthrough LED flashing technology, stacked wafer technology, global shutter, back-illumination, and support for automotive safety integrity ratings. Wait. Wu Zhimin said, for example, ON Semiconductor's 2 megapixel image sensor AR0231AT uses LFM technology to eliminate high-frequency LED flicker, meets the automotive safety integrity level B requirements, and has the ability to monitor embedded data and sensor faults. The security field is especially important.
NXP: Step by step to achieve driverless driving in four stages
Tian Yunfeng, senior manager of NXP's semiconductor microcontroller marketing department, said that the ultimate goal of smart cars should be as a platform to provide passengers with a variety of services, including transportation, intelligent control, driverless, entertainment and shopping, etc. Driving is achieved in four phases: assisted driving, semi-automatic driving, highly automated driving and driverless driving.
At present, many mid-to-high-end models on the market already have the function of assisting driving. Even some luxury cars have semi-automatic driving functions, such as emergency collision avoidance and automatic parking. Tian Yunfeng said that a truly self-driving car is expected to be available in batches after five years. Of course, this depends on the laws and regulations. For the development of smart internet, with the addition of a large number of Internet companies, it will greatly accelerate the intelligent interconnection of cars. Speed ​​of development.
In addition, due to the explosive growth of new energy vehicles in the past two years, some car manufacturers have neglected the management of quality in order to seize the market as soon as possible, and buried hidden dangers of quality problems. Tian Yunfeng emphasized that the experience of new energy vehicle development is still quite different from that of traditional fuel vehicles. There are bound to be many potential problems that have not been discovered in time. Once these problems and quality risks are concentrated, they will greatly reduce the confidence of customers in purchasing new energy vehicles. Damage to the entire new energy vehicle market.
