"It is a pity that if the road transport passenger car can introduce an active safety system, it can let the passenger car take the initiative away from the danger, and it will not have such a big casualty." Let Dai Jinlong new technology research and development department Dr. Chen Xiaobing lamented that this year 8 At the end of the month, there were three rear-end collisions in the Sichuan and Shaanxi provinces, which resulted in the terrible consequences of the fatal accident of 57 people.
Looking at the overall situation of passenger transport, the security issue is not optimistic. Minister Yang Chuantang of the Ministry of Transport pointed out at the National Telecommunication Safety and Teleconference Conference that from January to August, the number of road passengers operating heavy vehicles continued to increase, and the number of serious accidents and deaths increased by 22.2% and 29.6% respectively.
In order to further strengthen safety management, on September 1st, the new “Technical Conditions for the Operational Safety of Motor Vehicles†was officially put into effect. The new national standard put forward more stringent technical standards for passenger cars and other key models involving life safety. In addition to the strengthening of passive safety technology, the new national standard also explicitly stipulates active safety arrangements. For buses with a bus length of 6 meters or more, they should have a speeding alarm function. Highway passenger cars and tourist buses should have speed limit functions. Or install a speed limiter.
"The new national standard's hard regulation in active safety represents a new direction for the development of automotive safety technology, and it will also become a policy driving force to promote the safety technology upgrade of the entire bus industry. Active safety will undoubtedly become the next technological high ground for the safety performance competition of passenger cars in the future. "There are people in the industry who read this.
Multi-factor driving transformation active safety
If the implementation of the new national standard provides a policy direction for the safety technology development of the entire bus industry, then from the aspects of actual operation demand, the needs of the company's international competition, and the experience of mature markets, it will have more manpower, material resources, and financial resources. The investment in active safety technology for R&D has become an inevitable choice for companies.
With the globalization of bus industry, more and more Chinese companies have begun to move overseas. Active safety technology has become a threshold for companies to enter the markets of developed countries. In this respect, Dajinlong Bus, which has been fighting the European market for 10 years, has a deep understanding. Jinlong Technical Director Zhou Fangming told the reporter: “The active safety standards in the developed countries' markets are far higher than those in China, and we must take a place in these markets, and the transition to active safety technology in research and development becomes inevitable.â€
From the perspective of the development of the European market, European companies have long realized that relying solely on passive structures such as body structures and escape measures to improve safety is far from enough, and a series of active safety technologies have been put into use one after another. At the World Bus Expo held in Belgium at the end of 2011, a series of active safety equipment appeared on the booth of the European mainstream bus companies. What is more important is that these equipments have not only stayed on the show cars, but have also been popularized on passenger vehicles.
What is important is that from a practical perspective, a strict system cannot avoid loopholes in implementation and deviations from human operations. To minimize accidents, focusing only on passive safety and management systems is far from adequate. It is also necessary to start with the active safety of passenger cars and rely on technical means to make up for human uncertainty in order to reduce accidents.
Overall, the future R&D of passenger car products will tend to be intelligent, and active safety will become the most important aspect of passenger car intelligence. Policy-driven, competitive demands, and major accidents that continue to occur have set higher technical requirements for bus companies, and making active safety technologies the focus of research and development has become an inevitable choice.
Large car enterprises occupy the frontier of technology
In fact, domestic well-known passenger car manufacturers represented by Daikin Dragon have already quietly launched upgrades in active safety, and research and development achievements have begun to enter the application stage. Since July, Daikin has successively introduced three lane safety warning systems, a forward collision warning system, and a road automatic speed limit control system. It represents a brand-new technological trend in the active safety field of various companies, and it has not caused a stir in the passenger car industry. Small shocks.
Dajinlong's independent development of the Lane Departure Warning System (LDWS) was started as early as 2010. With the support of Xiamen's key production, research, and research projects, the system finally entered mass production at the end of June this year after long-term road tests, algorithm verification, and mold development. The system captures and calculates the relative relationship between the vehicle and the road marking line and can alert the vehicle that the vehicle is abnormally deviating from the current driving lane, providing more reaction time for the driver and greatly reducing the lane departure caused by fatigue driving. Traffic accidents.
In order to better solve the problem of passenger car speeding, Dajinlong successfully developed an automatic road speed limit control system in August this year. The system uses the "car networking" platform to limit the speed of different road sections (tunnels, high-speed entrances, exits, corners, ramps, etc.) on the vehicle's travel routes through electronic fences, and enforces speed limits on vehicles, providing personnel. In addition to another security guarantee.
In the prevention of rear-end accidents on buses, the forward anti-collision alarm system launched by Daikin Dragon provides the most reliable guarantee for drivers to make hazard avoidance in advance. Dajinlong forward anti-collision alarm system uses radar to detect the relative distance and relative speed between the vehicle and the obstacle in front, and uses an intelligent algorithm to judge whether it is a potential collision or not, and alerts the driver through sound, light and vibration alarms. It is worth mentioning that this system integrates the information of the car network in the algorithm design of the collision time and is the first in the world.
It is also known that in addition to the above three active safety systems, Daikin Dragon is seeking more scientific and technological achievements, and fatigue driving alarm systems and night-vision imaging systems are actively being researched and developed. This is also a technology leader in China’s leading passenger car companies. In miniature, the layout of various bus companies in the field of active safety technology has quietly begun.
Independent Innovation Testing Company Strength
Compared with developed countries, domestic active safety technology research and development is still in its infancy. Manpower, technology, and other resource reserves are not abundant, and the investment is huge and can not produce economic benefits in a short time. In the long run, active safety is the technical shortcoming that companies have to make up for. Therefore, improving corporate R&D capability has become a must-have issue for companies.
“Technological innovation and technological transformation are the future directions for the development of the passenger vehicle industry. Only technological innovation can promote industry upgrading. Whoever has the best in this area can lead the future. In today’s rapid development of car networking and intelligent technologies, Integrate science and technology such as artificial intelligence, automatic control, and CAE into bus R&D.†Guo Jinxiang, general manager of Daikin Dragon, has a cool mind, and this also reflects Dajinlong’s important ideas for active safety technology research and development.
In fact, from the second half of 2010, Dajinlong began to invest a lot of funds to build basic R&D capabilities, and promoted projects such as R&D centers, test centers, and production line transformation. At the same time, Dajinlong New Science and Technology Research and Development Department was formally established. It has accelerated the research on automotive electronics technology, new energy technologies, and active and passive safety technologies. This has also laid the foundation for R&D of "Golden Dragon".
Dajinlong's investment in research and development has brought products with higher safety standards. “Technology Golden Dragon†not only provides an important technical foundation for Dajinlong sales to exceed RMB 10 billion, but also will drive the overall upgrade of active safety technology in the passenger car industry. . It can be predicted that in the future for a long period of time, the technical competition on active safety will become the focus of the bus companies in China.
