China Automotive Safety Technology Development Forum discusses the future of automobiles

More and more new cars are on the road, more and more novice drivers are joining the ranks of street killers. How to reduce the incidence of traffic accidents on crises-ridden roads? This is not only a concern for consumers, but also an automobile manufacturer and parts manufacturer. Business and industry people have been studying the direction. Recently, at the 2013 (4th) International Forum on the Development of China's Automobile Safety Technology, held in Zhuhai, the answer to making cars safer seems to be simple and clear – let “smart” cars come on the road. Reckless human escort!

New version of C-NCAP will increase "5 stars"

Strengthen active safety assessment

How to just judge car safety? More stringent car safety technology assessment standards are necessary. In order to better assess the safety of new car owners, Liu Yuguang, deputy chief engineer of China's C-NCAP Management Center, revealed at the forum that the current C-NCAP rule will be upgraded again in 2015! According to the timetable, the current version of the C-NCAP evaluation protocol It is expected that the first draft will be formed in 2014 and finalized and announced in 2015. More active safety assessment will be considered.

The purpose of the upgrade is to make the C-NCAP rules more stringent on the assessment of new cars. In the pilot project, frontal, offset, and side collisions of the vehicle will be carried out, and a whiplash will be carried out. In terms of star rating, a high star threshold will be set, including "5 stars" and " 5 star rating.

"From a medium and long-term perspective, the direction of C-NCAP research will focus on the four major areas of active safety, collision modes, measurement effects, and safety assessment." Liu Yuguang said that C-NCAP will pay more attention to the development of active intelligent security technology in the long term. New collision patterns (side column collisions, commercial vehicle rear-end collisions, etc.), measuring devices (WorldSID dummy and child dummy, mobile barrier, active safety test device) and more safety items (light tube performance assessment, pedestrian protection assessment) .

Child safety seat compulsory certification will be introduced next year

In many traffic accidents, child safety is becoming the focus of attention throughout the years, especially as the safety of children as car passengers is ignored by the majority of Chinese parents, while the uneven child safety seats allow parents to spend money for children, but actually Not guaranteed.

Previously, the National Standard for Vehicle Child Safety Seats, "Restriction System for Motor Vehicle Child Crew Members," was implemented on July 1, 2012. It is required that the production and sales of child safety seats must meet this technical requirement, but because the standard is only technical regulations and not legislation. Does not mean the mandatory use of child safety seats. “Child safety seats must have a legal basis!” Qu Yanping, China Quality Certification Center, said: The child safety seat 3C compulsory certification program will be launched at the end of this year. In 2014, the compulsory certification of child safety seats will begin. At the same time, the reporter was informed that China National Automobile Research Institute is currently planning to formulate standards for the protection of children's safety seats in the event of a car's side impact. This collision situation is not covered by current standards.

The popularity of intelligent systems

"Cracking" Artificial Traffic Accidents

OEMs and domestic and foreign parts and components companies are strengthening intelligent assistive technologies, and will gradually switch to autonomous driving in the future, thereby avoiding accidents caused by inoperable people during driving, and reducing the incidence of accidents. As the largest technology supplier of automotive intelligent auxiliary systems, Bosch and Continental Group have stated that they have increased their R&D and production in automotive intelligent auxiliary systems in recent years.

Chen Liming, president of Bosch's chassis control system in China, said that its advanced driver assistance systems, including predictive emergency braking systems, adaptive cruise, road sign recognition, and object recognition technologies, will gradually transition to autonomous driving in the future. James Remfery, director of intelligent technology for the integration and application of chassis and security systems at the Continental Group, told reporters: The goal of the Continental Group is to replace the driver’s perception and observation of roads and vehicles with intelligent assistance systems (including ESCs, lane departure warnings, automatic emergency braking systems, etc.). Conditions can reduce traffic accidents caused by human errors.

The Continental Group predicts that from 2016 to 2025, the development of autos from primary autopilot, advanced autopilot to full autopilot will be realized, which will greatly reduce the accident rate. “Beginning in 2016, some automated systems will provide drivers with 'start-stop' assistance on the road at speeds not exceeding 30km/h, and in 2020, advanced automated driving technology will improve when put into use. The speed of more than 30km/h, advanced automated driving technology can help perform other activities during normal driving hours, such as reading the Internet while driving, on Weibo, etc."

Active and passive security system upgrade

The future car knows how to protect people

At present, in some models produced in China, the ACC system, AEB system, and LDW system have been used, which not only reduces people's driving safety hazards, but also improves the convenience and comfort of driving. In fact, there will be more intelligent auxiliary systems being used in new cars in the future.

Delphi said that it is studying occupant monitoring systems (PODS), radar and visual fusion systems (full-speed ACC, traffic Peugeot identification systems, etc.) and human-vehicle interaction systems (monitoring and evaluation of driver patterns to control brakes, steering and engine systems). And so on, most applications have already been obtained. Yanfeng Bailide Co., Ltd. said that adaptive seat belts, inflatable seat belts, knee airbags and adaptive airbags (according to the occupant's size, collision patterns, etc. to determine the shape of airbags) will be smarter and smarter in the future, reducing collisions in traffic accidents. Inflicts damage to passengers due to airbags and seat belts, and provides better warning protection.

In the next few years, cars will be "smarter" than they are now to protect passengers and even allow passengers to reduce injuries in serious traffic accidents. These are not the whims of R&D experts. Wang Zhenfei, the system engineering manager of TRW Automotive Research & Development (Shanghai) Co., Ltd., introduced a "standard" technology that may be implemented on all models in the future - the reversible pretensioner technology. This technology can work in different collision scenarios. The reversible pretensioner can reduce the occupant displacement in emergency braking and emergency steering of the vehicle, thereby avoiding the damage caused by the front, side airbags, and the body due to improper position after the occupant is displaced. . He said that this technology may enter the E-ncap rating system in the future. This means that cars in the future can better protect passengers in the car.

Grips are usually made of firm or soft plastic, foam, gel, or sometimes leather, depending on expected use or desired price. They may be simply smooth and round or molded to fit the shape of a human hand better. Foam grips can be applied by submerging them under water and then inflate them with 200,000 Pa (30 psi) air while massaging them onto the handlebar. A quick way of fitting foam grips is to spray the ends of the bars liberally with hair spray and then slide on the grips and adjust their rotation quickly; leaving them alone, the hair spray will soon fix them in position. Plastic grips can be heated in water and punched onto the handlebar. Finally, a small amount of isopropyl (rubbing) alcohol may be applied to the bar surface during removal or installation of grips in order to provide lubrication, which when allowed to dry, leaves no residue.
