What links does C-NCAP automobile crash test include? Is it credible?

As an advanced automobile safety collision detection institution in China, C-NCAP collision results have attracted many automobile enterprises and countless consumers, because the safety star rating of safe and arduous collisions will directly affect the future automobile sales and consumers' choices. So what are the C-NCAP values of many car companies and domestic drivers? Compared with other similar institutions, does it have outstanding advantages? Today, the author will unveil the mystery of C-NCAP.

Let's take a quick look at C-NCAP.

I believe that domestic drivers are no strangers to C-NCAP. Founded in 2006, the organization comes from China Automotive Technology Research Center Co., Ltd. This organization comes from the global NCAP system and has been developed in China for more than ten years.

At first, C-NCAP drew lessons from European E-NCAP, Japanese J-NCAP and some test items including A-NCAP, and deeply combined with China's road conditions, driving habits and accident data.

C-NCAP has a good safety test standard. For the first test, the whole fuselage needs to be very high, and there are full-scale test items, including the well-known frontal 100% complete frontal collision, 40% offset collision test, deformable moving side collision and so on.

Secondly, C-NCAP requires high safety of automobiles. The 20 18 version of C-NCAP has the requirements of reminding the rear seat belt and putting multiple sensors on the real response of the human body, so the chest, abdomen and legs are tested. Different from Europe, there are more and more SUVs in China, and the use of vehicles is more important, providing services for family occupants, so safety is particularly important. From 20 12, C-NCAP began to test planners, and a lot of technical accumulation and experience were also invested in foreign institutions. Nowadays, electronic NCAP, J NCAP and so on. Will improve the scores of personnel.

In addition, C-NCAP also has high requirements for automobile safety, such as active safety and pedestrian protection test, which is the test plan launched this time. The score of this test is much higher than that of E-NCAP, which has become an important indicator to measure the safety of the vehicle.

What does the C-NCAP test mean?

Based on the development of automobile market, C-NCAP has really entered the pace of keeping pace with the times. Looking back, since 2006, more than ten C-NCAP rules have been published more strictly every three years, which shows the overlapping process.

What is more stringent than European testing standards? C-NCAP automobile safety collision test shows that in each revision and update, C-NCAP will deeply understand the data about traffic accidents in China in CIDA Report, and adjust and upgrade the test methods. The details of the collision assessment system are exactly the same as the actual vehicles used in China.

Compared with version 20 15, the evaluation system of version 20 18 has changed. The previous vehicle occupants passed the passive safety protection evaluation of external pedestrian protection performance and vehicle active safety performance, which comprehensively covered the main passive safety requirements and increased the evaluation of pure electric and hybrid vehicles.

Let's talk about the safety requirements of cars first. For example, the AEB test project is a famous automatic emergency braking system. How big is the role of AEB system? Previously, the European NCAP found that due to the analysis of traffic accidents, 90% of traffic accidents were due to the driver's attention. AEB can assist drivers to brake through the system while detecting danger, thus reducing or avoiding accidents.

However, for this project, the test scores of C-NCAP and E-NCAP are completely different. The total score of the three AEB sub-projects of C-NCAP is 12.2, and the project of E-NCAP AEB only accounts for 3 points. The difference between them is that the population of China is much higher than that of Europe, and the traffic awareness of most people needs to be improved. When an accident happens, most car owners take the initiative to brake. For China car owners, AEB system is more important than seat belts, and then the test items are heavier.

In order to meet the requirements of automobile safety, for domestic automobile safety, the test standard and final score of C-NCAP will also meet the domestic automobile conditions.

For example, according to the current understanding of the data, it is already the most stringent version 20 18, not 20 15, which not only improves the sub-temperature speed of 2 1 km/h, but also increases the safety of the first air curtain, the seat belt reminder device on the back and the collision mechanism with technical requirements.

In addition to whipping test, active safety, pedestrian protection, child protection, etc. On this basis, all items such as electronic NCAP test and electronic safety test have been added to ensure the comprehensive test scope.

With the gradual improvement of people's requirements for automobile safety standards, the strictness of C-NCAP testing is also constantly strengthening. It is expected that 202 1 will introduce touch test and side column touch, which seem to be more stringent test contents. What is more stringent than European testing standards? Interpretation of C-NCAP Vehicle Safety Crash Test

Then, for the safety of bus relay personnel, C-NCAP is combined with the national conditions of China, and car consumption in China is related to home users. Because the children and the elderly who get rid of the post-knight often become special objects of special care for cars, the utilization rate of rear seats is much higher than that in Europe. It is reported that C-NCAP has the world's leading test dummy 4. In the main police, there are two adult male dummies, a female dummy and a 3-year-old child dummy, which completely simulate the actual trip. Happen. There are more than 100 sensors on the surface of the dummy, so as to simulate the real reaction of the human body in collision more accurately.

In addition, there are complete frontal collision, 40% offset collision test and deformable moving side collision.

In the frontal 100% overlapping rigid guardrail collision test, the collision speed should not be less than 50km/h ... This test simulates most vehicle environments, such as hitting trees, walls or rear-end collisions. It mainly tests the overall protection ability of the front engine compartment of the vehicle, the deformation of the engine compartment, the working condition of the airbag and the restraint of the seat belt.

The 40% overlapping barrier crash test is to test 40% of the vehicle's head area (driver's side), with a height 1000mm and a thickness of 540mm in front of 64 km/h. This test is mainly used for frontal, side and rear-end accidents, and it is the most important accident form at present.

Compared with the previous edition of 20 15 and C-NCAP 20 18, the side impact test requires that the weight of the cart be changed to 1400kg, and the center of gravity be increased from 450mm to 500mm, while the center of gravity comes from China. The SUV market is increasing year by year, which is more suitable for the traffic environment in China. Due to the decrease of the side sill beam, the impact force on the side sill beam is increased.

The above test is to ensure the fairness and objectivity of the collision. All sample cars are tested by ordinary consumers for C-NCAP in the market. The testing process is open and transparent. The result, indeed, is not affected at all, and it is really objective and true.

C-NCAP is unusual for consumers.

As China people pay more and more attention to automobile safety, the significance of C-NCAP is particularly important.

As a non-profit organization, it can fundamentally guarantee the objectivity and fairness of test data, thus providing consumers with vehicle safety information and promoting the improvement of vehicle safety and technical level.

Conclusion: C-NCAP, as an authoritative automobile collision detection institution in China, adopts advanced experience and strives for the detection standard, becoming the "authority" of automobile enterprises and many consumers. It can provide reference for consumers to buy cars and help vehicle companies optimize their products. If we compare the safety performance of the car, besides the increasingly abundant safety configuration, we can also show the difficult strength and safety of the car through the collision results of C-NCAP.
