·Intelligent car technology is moving from high-end to popularization

Smart car technology has become a battleground for military strategists. “The data shows that the proportion of electronic and electrical products in new energy vehicles has increased from 10% to 30%, while the proportion of smart technology-related products in electronic and electrical products has increased from the previous 1/3 to over 50%. Wang Jian, director of the Electronic and Electrical Development Department of the New Energy Project Group of Geely Automobile Research Institute, said.
In recent years, smart car technology has developed rapidly. Deng Xianghong, the chief engineer of the National Automobile Standardization Technical Committee, said: "By sorting out related technologies, we have roughly divided the smart car technology route into three, one is the car bus, the safety technology, the ADAS. (Advanced driver assistance system) and semi-automatic driving-based intelligent control technology; the second is based on information, entertainment, navigation, monitoring and other Internet applications to achieve entertainment and comfort functions, namely Telematics technology; the third is intelligent transportation System (ITS)."
Technology development always precedes industrial applications. Although many experts believe that smart cars are still at the level of “primary school students”, the development of smart car technology is already ahead of its application. From the technical level and development plan of various enterprises, ADAS technology is gradually moving from high-end models to low-end models. Popularization, car networking technology has also evolved from a simple car-connected to V2X.
ADAS function multi-application can't be "high on"
The Advanced Driver Assistance System (ADAS) uses various sensors installed in the vehicle to collect and process dynamic data of people, vehicles and the environment inside and outside the vehicle, so that the driver can detect the dangers that may occur to draw their attention or when necessary. A series of advanced technologies for interventional operations.
Wang Jian introduced the development of Geely's ADAS technology, including panoramic imagery, semi-automatic parking, blind spot monitoring, lane departure and high beam headlight control. “The Volvo system is mainly based on security protection and remote diagnosis, but it still needs to be improved in assisted navigation and data analysis; Borui system is mainly security technology and driving initiative technology, and some improvements have been made in the interior environment monitoring. "Wang Jian said.
Achieving “zero accident traffic” is Honda’s ultimate goal. To achieve this goal, Honda integrated the millimeter wave radar with the camera and released the SENS-ING system. Hengshan Lifu, senior director of the Automotive Research and Development Center of the Honda Institute of Technology, said: "SENSING has the function of recognizing pedestrian accidents and reducing collisions. This is the world's first pedestrian accident reduction steering function. It also has lane departure control function and prompting function for the front vehicle. , ACC (automatic cruise function), logo recognition function. Honda will use these technologies to further develop safe automatic driving support technology." "Hella believes that ADAS has the advantages of safety, convenience and efficiency." Hella Shanghai Electronics Co., Ltd. Ji Feng, manager of the new product and new technology department, said. At present, Hella's radar products mainly include blind spot monitoring, lane change assist and reversing collision warning function. Ji Feng said that these three functions have been verified by the market and widely used. In addition, the getting-off assist function has also been developed in the early stage, and blind spot monitoring for trailers is being developed. Jifeng said: "Hella believes that more new features will appear in the market in the future, but to achieve the goal of zero casualties, ADAS can not be high, from high-end cars to intermediate cars, economic cars."
The Internet of Vehicles technology has developed ADAS from the development of the vehicle to V2X, and then talk about Telemat-ics. The so-called Telematics refers to in-vehicle systems, including in-vehicle entertainment, car navigation, voice communication, etc., which can be extended to the Internet of Vehicles in a broad sense.
According to Chen Ping, chief engineer of BAIC New Energy Automobile Co., Ltd., the Internet of Vehicles is centered on big data, and it is necessary to create an open and connected platform to establish a complete integrated travel experience. "We think it has four cores, namely, one machine, one core, one APP, one center. One machine is the central control host in the car, it is a human-computer interaction interface that can display all information; one core is communicated by the outside world. TBOX; an APP is a mobile APP, which involves remote information control; a center is a back-end data center. In addition, five key technologies are needed for human-computer interaction technology, communication and interconnection technology, big data, cloud services, and software technology. Explain. “Car networking technology is one of the two key technologies of GAC. At present, GAC is doing V2X, including communication between vehicles and vehicles, and communication and control between vehicle and transportation system ITS.” Executive Vice President of Guangzhou Automobile Group Automotive Engineering Research Institute Chang Wu Jian said, "Guangzhou Automobile has established a very powerful Telematics system based on the platform of the car. TBOX is mainly based on the in-vehicle network and the system of 34G wireless network and Internet triple play. It is widely used in the self-owned brand of GAC Group. In the car, remote monitoring, remote start flameout, remote diagnosis and other functions are realized."
Geely's car networking technology is also based on the interconnection of mobile phones and car machines. Now it can realize functions such as remote control, remote mobile phone inquiry, remote monitoring and pointing control, remote start, remote switch air conditioner, and door switch and window lift.
Chip and sensor technology is fundamental and forward-looking Whether it is ADAS or the Internet of Vehicles, all smart car technologies are inseparable from chips and sensors. “Whether it is an ADAS or a smart connected car, or the realization of any function, we must implement it at the chip technology level 5 or even 10 years ago, and then provide it to the OEM or system integrator to complete the verification at the system level, and finally install it. To the whole vehicle," said Xu Hui, head of the Automotive Electronics Division of Infineon Technologies (China).
Back to the smart car technology itself, Xu Hui believes that there must be sensors with high performance and different functions. She said: "The distance detection between the two places is a challenge internationally, and China is lacking in this technology. Infineon has introduced a 77G radar chipset that can be used for remote detection, which is a necessary stage for ADAS implementation in the future. In addition, in Xu Hui's view, security-related control data needs to be protected, including not only the internal vehicle system, but also the transmitted information. From the chip perspective, different chips can be provided for encryption.
Freescale Semiconductor's product and market development manager Qi Yunxia introduced the functional realization of ADAS from the perspective of radar. "There are two main ways to implement ADAS. One is the radar method, which mainly refers to millimeter wave radar and micro wave radar; One is through the camera, also known as visual ADAS. Visual ADAS is relatively mature in China, including smart front view, rear view and surround view, but the first radar in China has no system suppliers to do."
According to market demand, Freescale not only improves the integration of the chip, but also applies the multi-core system on the processing chip, and puts the separated functions into the chip. Yu Yunxia said that visual ADAS is an inevitable trend from standard definition systems to high definition systems. How do you implement HD systems? This requires Ethernet. "Ethernet bandwidth is very wide, can meet the big data requirements, and is very flexible and low cost. According to predictions, by 2020, 25% of HD systems will be implemented based on Ethernet."
The development plan of smart car technology for car enterprises: Geely Automobile: The application plan of Geely smart car technology is mainly divided into three major directions: multi-directional communication, mainly emphasizing the external transmission of vehicle interior data, the transmission of communication data between vehicles and vehicles, Transmission of road information in the vehicle and transportation sectors, intelligent navigation and transmission of vehicle and road monitoring equipment information.
The second is the system self-learning ability, which is mainly for collecting user driving habit data, evaluating user driving habits, and improving user driving habits.
The third is to add new features from entertainment, navigation, communications, security and other aspects. For example, the entertainment system increases public comments, online news, navigation to increase real-time road conditions, security is mainly burglar alarm, emergency rescue, vehicle condition reminder, remote control, personalized settings, etc. This is the main direction of Geely 2.0 version of the car network planning.
Geely will do some related work in the automatic driving technology later, and more will be in the active high beam control, hoping to achieve the light type change. In terms of driving assistance systems, it is hoped that system integration will be realized, from a single automatic control function to a multi-functional combination. Geely hopes to achieve automatic driving on the highway by 2020.
Guangzhou Automobile Group: GAC Intelligent Vehicle Technology Road is divided into three stages:
In the first stage, the function of developing automatic driving is realized; in the second stage, various automatic driving road tests are realized, some subsystems are industrialized, and V2X is perfected in the aspect of vehicle networking, and charging between the vehicle networks is realized at the same time. Technology R&D; The third phase is to build an information cloud and energy cloud platform, and at the same time cooperate with the government to establish a smart car demonstration park, and then form an industrial cluster of intelligent automobile industrialization.
At present, GAC is in the second stage. This stage is mainly based on the achievements of smart car technology to break through in two areas. First, it is networked, and it is necessary to gradually realize the construction of information cloud and energy cloud. On the other hand, it will be These functions are driving applications in conventional vehicles, such as automatic parking systems and adaptive cruise systems that have been introduced to conventional vehicles and are immediately available on the market. In fact, the most important work of the second phase is to carry out in-depth development of the current V2X, based on the information cloud platform, to solve the problem of computing power of the embedded computer.
BAIC: BAIC's smart car technology is mainly divided into two levels:
