The Collision between Tradition and Reality in China Insurance Research Institute

On February 16, China Insurance Automobile Safety Index Management Center released the latest crash test results of China Insurance Automobile Safety Index (C-IASI)20 19, Changan CS75? PLUS has attracted wide attention from the industry with six outstanding (G) achievements.

Since the results of the C-IASI crash test were announced last year, many hot-selling models involved in the test have fallen into ruins, including German models known for their safety. Want to get a high score in the C-IASI crash test? It is very difficult.

How strict is the evaluation standard of C-IASI?

C-IASI is a difficult automobile safety test jointly established by China Automotive Engineering Research Institute and China Automotive Technology Research Institute. Different from other automobile safety assessments, C-IASI is dominated by relevant institutions in the insurance industry that are consistent with the interests of consumers. It aims to evaluate the direct cost of vehicle safety and vehicle maintenance after collision to insurance companies through more rigorous tests. Therefore, the detection results have high independence and credibility.

In terms of test items, C-IASI adopts a similar way to American IIHS, including main driver's 25% offset collision, side collision, roof strength, seat/headrest test, pedestrian protection, auxiliary safety test, etc. , and "G" means that the results of each item are excellent, "A" means good, "M" means average and "P" means poor. In addition, the test vehicles are randomly purchased by the management center in the regular channels of the market, and the test vehicles are all low-profile models.

IIHS, full name insurance? Institute? For what? Highway? Safety (American Highway Safety Insurance Association) has the strictest safety collision standard in the world, and the C-IASI evaluation standard is almost implemented with reference to the American IIHS evaluation standard, which means that the collision intensity is far less than the new car evaluation regulation of China (C-NCAP).

As can be seen from the table, the mobility obstacle of C-IASI is nearly twice as high as that of C-NCAP, and that of IIHS is 1500mm.

For a simple analogy, the collision object simulated by C-IASI is a compact SUV with CR-V size, the collision object simulated by C-NCAP is a compact sedan with sagitar size, and the collision object simulated by IIHS is a compact pickup truck with higher ground distance.

When a car's height guardrail hits the side of the car, it will first hit the lower guard plate and then hit the door, and the lower guard plate will absorb some of the impact force. After the height of the guardrail is increased, the side collision will directly hit the door, which will increase the impact on the window and B-pillar, and the body design and material rigidity will face a more severe test.

In addition, according to IIHS, C-IASI also introduced a frontal 25% offset crash test, in which the vehicle collided with a fixed rigid guardrail at a speed of 64.4km/h, with an overlap rate of 25% (on the driver's side). By simulating the collision of vehicles at a speed exceeding 60km/h, the safety quality is analyzed according to the damage of vehicles and the injury of dummies in the vehicles. Not long ago, the domestic Passat suffered a big loss and got a poor (P) score.

Therefore, in the workshop, PICC Research Institute was dubbed as the "magic mirror" of the automobile industry by domestic netizens and won the title of "the most stringent collision standard in domestic history".

Changan CS75? PLUS sets a safety example for domestic cars.

For the consumer market, it is a good thing and an inevitable trend for the automobile collision safety standards to be continuously improved. For car companies, this is an opportunity to distinguish between good and bad. Only companies that pay enough attention to automobile safety and have forward-looking reserves of automobile safety technology can calmly cope with the tests of different difficulties. PLUS is a particularly typical example.

IASI? 20 19 the second batch of changan CS75? PLUS evaluation results show that:

Excellent (G) evaluation was obtained in terms of occupant safety index, among which the evaluation results of frontal 25% offset collision, side collision, roof strength and seat/headrest were excellent (G).

Frontal 25% offset collision means that the test vehicle collides with a rigid obstacle 6 feet high and about 25% of the vehicle width at the driver's side in front of the vehicle at a speed of 64Km/h, and the driver's position is hybrid? Three? The 50th crash dummy mainly simulates the collision with oncoming cars, roadside trees and telephone poles in reality.

Immediately after the collision, the body structure, door and A-pillar doorsill were observed with naked eyes. The front door frame, steering column and instrument panel were in a stable state after the test, and the integrity of the passenger compartment was excellent, which effectively guaranteed the living space of the passengers.

After the door is opened, the performance of the restraint system can be observed. The airbag exploded normally, the dummy's head dyed the airbag normally, and the hard objects such as the roof beam and glass were not dyed, indicating that the head was well protected by the airbag and had not been exposed to other hard objects; The side air curtain detonated normally, effectively supporting the head and not deviating from the plane of the window.

After the side impact, the door displacement is not large, the B-pillar is basically intact, the side air curtain and airbag are all opened, and the ceiling is intact.

Changan CS75? PLUS's roof strength project also performed well. The test results show that the peak load of the vehicle is 69240N, which is 4.43 times of the vehicle weight and 4 times higher than the excellent standard. This also proves from the side that the materials of Changan CS75PLUS from A-pillar to B-pillar to C-pillar are solid, and the proportion of high-strength steel is quite high.

In terms of the safety index of drivers and pedestrians, the head test score was 14.857, and the leg test score was 6.000, with a total score of 20.857 (the scoring rate was 69%), and finally the excellent (G) evaluation was obtained.

In terms of vehicle auxiliary safety index, Changan CS75? The type of PLUS sensor is millimeter-wave radar+monocular camera, and its FCW score is 1, AEB score is 5, with a total score of 6. Finally, it gets excellent (G) evaluation.

Changan CS75? PLUS got excellent (G) rating in frontal 25% offset collision, side collision, roof strength, seat headrest, pedestrian protection and FCW/AEB test, which is not easy. All these indicate that China automobile industry, represented by Changan Automobile, has made great progress in recent years.

If we pull the score to 20 19 again? C-IASI perennial test model, compared with Changan CS75? PLUS has more than ten models of the same class. Among them, there are many models of world-renowned brands such as BMW, Volvo and Ford. Under the standard of C-IASI, Changan CS75? Plus the safety performance of these models is equivalent!

Some people may be curious that a traditional car company will launch a new car. Generally speaking, it takes at least three years from project approval to mass production. And C-IASI was released last year, Changan CS75? Plus it was only listed at the end of last year. In other words, Changan CS75? The R&D work of PLUS was carried out long before C-IASI announced the rules and regulations. Changan CS75? Why can PLUS achieve such good results?

The answer is that in recent years, Changan Automobile has been doing collision tests with reference to IIHS standards, and the C-IASI evaluation standards are almost implemented with reference to the American IIHS evaluation standards, so it is not surprising that Changan CS75PLUS got high scores.

This foresightedness urges Changan to set higher standards for itself, to continuously expand its reserve of advanced automobile safety technology, and to take the initiative to assume the important responsibility of ensuring the safety of society, consumers and all traffic participants. Just as all schoolmasters are not satisfied with what they have been taught in books and passed the examination syllabus, they are invincible in the examination room because their knowledge reserves have already surpassed ordinary students. Therefore, even if the exam is difficult, they can still relax and draw inferences.

Therefore, Changan Automobile has always achieved good collision results: in 20 12, it won the first five-star position in China, in 20 13 XT, in 20 14, it won the highest score of its own brand, in which CS75 broke the C-NCAP record and in 20 17, changan CS95 also got the highest score.

Safety is not limited to the car body.

In addition to passive safety, Changan Automobile believes that the air quality inside the car is also very important. If the benzene content exceeds the standard, it is not good for the occupants to stay in the car for a long time. Therefore, Changan Automobile, as the drafter and editor-in-chief of the draft "Evaluation Guide for Indoor Air Quality of Passenger Cars" (revised GB/T27630-20 1 1), has extremely strict requirements on indoor air quality.

In addition to strict control of odor and VOC, Changan CS75? PLUS also comes standard with forests? Air forest air purification system+intelligent climate health control system.

It only needs to be turned on for 3 minutes, and the air inside the car is reduced from the heavily polluted state with the concentration of PM2.5 as high as 750ug/cm3 to the forest air quality below 23ug/cm3. After being turned on for 30 minutes, the concentration of negative ions in the car is more than 2800 /cm3, which can effectively sterilize.

Disposable medical masks can prevent PM5.0 and coronavirus, while forests? The air forest air purification system has four layers of activated carbon filter elements, which can prevent smaller PM2.5 particles, and the overall filtering effect is close to that of N95 mask.

At the moment when the epidemic is raging, it can effectively protect passengers in the car.

This is exactly where the safety of Changan Automobile is different from that of other automobile enterprises.

Changan Automobile is an enterprise with strong engineer culture.

Changan CS75? Behind the high score of PLUS in C-IASI crash test, it is also the embodiment of R&D ability.

Over the years, Changan Automobile has focused on basic R&D investment and invested 5% of its sales revenue in R&D every year. Since the 11th Five-Year Plan, more than 50 billion yuan has been invested. At present, Changan Automobile has built 194 international advanced laboratories, covering 16 fields such as vibration and noise, collision safety, braking performance, chassis test and drive system, among which the automobile noise and vibration and safety technology laboratory is the national key laboratory; Invest 2 billion yuan to build an international standard Chang' an Dianjiang proving ground; With 1. 1000 technicians and 400 senior experts from 15 countries, it ranks among the best in the automobile industry in China.

According to the evaluation of the National Development and Reform Commission, Changan Automobile's R&D strength has been ranked first in China automobile industry for 10 years. As far as automobile safety is concerned, any new model produced by Changan must undergo more than 40 crash tests before it is developed and officially put on the market. The purpose of this crash test is to provide consumers with the safest car.

It is not difficult to see that Changan Automobile is the most engineer-oriented automobile enterprise in China, and this ingenuity will lay the foundation for Changan Automobile 10.
