As a strategic emerging industry with a new economic growth point, the Internet of Things is another trillion-level market after the communication network, covering various applications from sensors and controllers to cloud computing. Products and services involve smart home, transportation and logistics, and environment. Protection, public safety and other fields. According to relevant forecasts, the Internet of Things will reach a market value of 1.3 trillion US dollars in 2019. By 2020, the scale of China's Internet of Things industry will reach 2 trillion yuan.
The networking in smart cars is commonly known as the Internet of Vehicles. It is a huge interactive network composed of information such as vehicle position, speed and route. It can complete its own environment and status information through GPS, RFID, sensors, camera image processing and other devices. The acquisition finally allowed the car to gradually reach two basic goals: driverless and intelligent network. To this end, electronic enthusiasts interviewed Tian Yunfeng, senior manager of NXP's semiconductor microcontroller marketing department, in the hot field of smart cars, to facilitate readers to better understand the future development trend of the car and the current challenges.
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. According to Tian Yunfeng, the truly self-driving cars are expected to be available in batches in 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, the intelligent interconnection of cars will be greatly accelerated. Speed ​​of development.
This will also promote the popularity of the car and people, cars and the cloud, voice control, complex gesture control, intelligent navigation, intelligent diagnosis and other applications will be used on more models. Tian Yunfeng pointed out that the main difficulty in the development of the smart car market is excessive cost, especially various sensors, such as laser radar, millimeter wave radar, etc., as well as the accumulation of autopilot experience data. In different countries and regions, traffic conditions vary widely, and it is difficult to adapt a set of empirical data to different situations. For example, when a driver in one country drives a car in another country, it takes a while to adapt to the local traffic conditions. .
When talking about the future business opportunities of domestic automakers, Tian Yunfeng pointed out that assisted driving and intelligent network networking are the most important business opportunities in the next three years, such as lane departure detection, panoramic viewing, semi-automatic parking and other applications. For autonomous driving and unmanned driving, Chinese automakers still need a long time to do system matching and experience accumulation, so there will be no good opportunities in the short term.
The technical difficulty of intelligent network is lower than that of unmanned driving, especially for many Internet companies that have joined the automotive industry. Tian Yunfeng further pointed out that the demand for intelligent network connection may be more urgent than the demand for unmanned driving. Many domestic suppliers have little gap in the technical level of intelligent network connection and foreign countries. Therefore, applications such as voice control, intelligent navigation, intelligent diagnosis, and vehicle-to-road communication are very good opportunities for domestic OEMs.
Tian Yunfeng added that NXP has an ADAS technology solution based on vision and radar, and has the most mature V2X complete technology solution. In addition, the high-performance i.MX product line provides a powerful computing platform for intelligent network, and encryption technology provides communication security for intelligent diagnosis, intelligent control, and vehicle-to-road communication. In the field of new energy vehicles, NXP's motor control and battery management systems are also very advantageous.
The motor control scheme includes drive motor control, electronic water pump control, electric vacuum pump control, and air conditioner electric compressor control. Tian Yunfeng said that the motor control solution has the following five advantages:
1. NXP products include a variety of microcontrollers, pre-drivers, Mosfets, position sensors. Its rich product range can meet a variety of performance, functional safety, volume requirements;
2. Strong technical support from a team of motor experts from around the world;
3. Use Matlab to create models, online simulation tests, directly integrate the motor control model and various modules, automatically generate code, and download directly to the microcontroller to run;
4. Provide product-level math function library and motor control function library, which greatly saves development time;
5. Provide a variety of evaluation boards and reference designs, software code, etc., users can quickly become familiar with the program.
At the same time, NXP battery management system is the most complete solution on the market, including microcontroller, power management basic chip, relay driver chip, CAN transceiver, battery current and voltage temperature detection chip and collision sensor. Tian Yunfeng pointed out that the solution meets the functional safety ASIL-D requirements, and can provide MCAL that meets AUTOSAR, as well as high-quality automotive-grade products.
In response to the current domestic new energy vehicle market, Tian Yunfeng said that the Chinese market is the world's largest auto market and will determine the future direction of new energy vehicles. In order to meet the 2020 goal of 100 liters and 5 liters and receive subsidies for new energy vehicles, PHEV/EV will be the main development direction of their main brand OEMs, and 48V HEV will be the main development goal of European and American joint ventures, and the future impact. The main challenges in the development of the new energy vehicle market come from cost and quality.
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. Inflicted damage on the entire new energy vehicle market.
