Revealed | 25 years ago, the pioneer of China's automobile collision test

After the "First Crash in China" in 1998, the domestic vehicle safety collision test was Put it on an important agenda and begin to align with international practices.In 1999, scientific research institutes under the State-owned Assets Supervision and Administration Commission began to introduce the concept of NCAP collision testing abroad and formulated stricter safety standards. In the 25-year history of China's automobile safety evolution, there is also a gray episode in the middle.

As the organizer and witness of "China's First Collision" that year, Professor Zhang Jinhuan, director of the Automobile Collision Laboratory of Tsinghua University, gave Shenlong Automobile a high evaluation. "The successful collision of Shenlong Fukang 25 years ago showed the safety and reliability of Shenlong's products themselves. Even today, Fukang The safety quality is still excellent.

In recent years, a new collision testing institution has emerged. The well-known domestic car companies seem to have been exposed all of a sudden. The difference in the performance of some models is amazing. That's right, it is the China Insurance Research Institute, which has been in the light recently.

Since 1999, China Automobile Research Institute has been committed to actual vehicle collision tests. For more than 20 years, C-NCAP (China New Car Evaluation Regulations) has also become one of the main evaluation systems in the field of automobile safety in China.

What do the 24 safety monitoring of cars monitor?

1. Automobile safety inspection items: specifically including appearance, braking system, steering system, transmission system, lighting (signal indicator light) and tires. Each part of this must be normal. Once there is an abnormal situation, it is in the process of road operation. Prone to traffic accidents.

2. Safety side slip, steering, braking, headlights.Environmentally friendly noise and exhaust emissions. Dynamic speed, acceleration time, chassis output power, engine power, torque and ignition system, and oil supply system. Economical fuel consumption. Reliability abnormal noise, wear, deformation, cracks.

3. Tire monitoring. Tires are the four feet of the vehicle, which are the only one to ensure safe travel. If there is wind and snow during the Spring Festival, the good operation of the tires is more important. Carefully check whether the tire pressure of the four wheels is normal, or whether the old tires need to be replaced.

4. The inspection of the relevant performance of automobiles, and the use of special automobile inspection equipment to carry out the inspection of automobiles. According to the requirements of the "Measures for the Administration of Motor Vehicle Safety Technical Testing Stations" of the Ministry of Public Security of the People's Republic of China for the equipment of inspection equipment, it can be divided into the following 6 items. ( 1) The steering wheel slides sideways.(2) Braking performance.

5. Automobile safety performance inspection mainly focuses on the inspection of automobile safety, such as steering wheels, brakes, speedometers and other accessories. Safety performance inspection is only an integral part of comprehensive performance inspection, mainly for maintenance technicians to do a whole vehicle inspection to find and eliminate vehicle safety Suffer.

6. It is reported that the vital sign monitoring system of VV6 mainly monitors the rear-row vital body through the millimeter-wave radar sensor on the left B-pillar of the car. The measurement accuracy of the millimeter-wave radar can reach the millimeter level. Even slight breathing and slight ups and downs of the body will be monitored in real time, which can avoid monitoring blind spots due to coma and deep sleep.

What does the safety performance test of cars mainly detect?

Car safety (braking, side slip, steering, headlights, etc.). Reliability (abnormal sound, wear, deformation, cracks, etc.). Dynamic (speed, acceleration capacity, chassis output power, engine power, torque, supply system, ignition system condition, etc.). Economy (fuel consumption).

Vehicle safety inspection is an inspection that focuses on automobile safety, such as the inspection of steering wheels, brakes, speedometers and other accessories. Safety performance inspection is only an integral part of comprehensive performance inspection.

Automotive safety detection: braking, zd steering, side slip, speed and lighting, etc.; work reliability detection: abnormal noise, wear, deformation and crack detection; dynamic detection: acceleration ability, chassis output power, engine power, circuit working performance detection; environmental protection detection: noise and exhaust exhaust Detection of the situation.

Safety inspection mainly involves the inspection of safety and environmental protection projects; comprehensive performance inspection is a combination of a variety of technical properties such as vehicle dynamics, safety, fuel economy, reliability of use, exhaust pollution and noise, and the completeness of the whole vehicle equipment.

Safety performance testing focuses on items in terms of safety performance, and comprehensive performance testing is the detection of multiple items including safety performance.
