Whether the safety performance of a new car is measured is not up to the manufacturer to make the final decision. It must be verified by experiments. in"car"Crash safety performance test" is one of the main items and the test item that people are most concerned about. Because most of the car accidents are collisions, the test results basically reflect the safety degree of the car to occupants and pedestrians.
The United States, Europe and Japan have all formulated relevant occupant collision protection safety regulations. For example, the National Highway Traffic Safety Administration (NHTSA) promulgated the FMVSS208 "Occupant Collision Protection" regulation, the European Union revised ECER94.01 "Frontal Collision Occupant Protection" regulation, and the Japanese Ministry of Transport issued the TRAIS11-4-30 "Frontal Collision Protection" regulation. "Safety Standards" regulations, etc., regularly conduct frontal or side collision safety tests on domestically produced and imported new cars to check the degree of injury to the driver and occupants of the car during the collision. However, these safety regulations are only the minimum requirements for the safety of automotive products by the government management departments of these countries or regions, and the automotive manufacturers pursue the industry-recognized NCAP (New Car Assessment Program), which is called the New Car Assessment Program in Chinese. . It is an industry organization that regularly sends new cars to companies or appears on the market for collision tests. The collision speed of real cars is often higher than the collision speed of the safety regulations formulated by the government, thus in a more serious collision environment. Evaluate the degree of injury of the occupants in the car, and classify the safety of the test car according to the degree of injury of the head, chest, legs and other major parts.

Evaluate the degree of injury of the occupants in the car, and classify the safety of the test car according to the degree of injury of the head, chest, legs and other major parts. Although NCAP is not a government-mandatory experiment, because of its extensive representation, scientific standards, strict testing, and fair organization, it directly announces the test results to consumers, and shows consumers which cars are safe or safest through crash tests. Therefore, major automobile companies attach great importance to NCAP and regard it as an important evaluation basis for automobile development. Manufacturers that have achieved good results in the NCAP test also use the test results as the promotion content of their products.
NCAP first appeared in the United States, and then countries such as Europe and Japan have formulated related NCAPs. Among them, the European NCAP (European New Car Assessment Program) is the most influential and representative. It is composed of European automobile federations, government agencies, consumer rights groups, automobile clubs and other organizations, and is led by the International Automobile Federation (FIA). Euro NCAP is not dependent on any car manufacturer, and the required funding is provided by the European Union. It conducts collision tests on new and imported cars that have been on the market from time to time, and organizes several times a year.
The Euro NCAP crash test has two basic items, namely frontal and side impact. The frontal collision speed is 64 km/h, and the side collision speed is 50 km/h. Inviting manufacturers to directly participate in a vehicle collision to show fairness, and allowing their products to have two collision opportunities. When the manufacturer learns that the results of the first collision are not ideal, they will improve the product or install safety devices, and then conduct a second collision. , To obtain the best result shall prevail.
NCAP's crash test results are indicated by the star rating (★). There are five stars. The higher the star rating, the better the crash safety performance of the car, reaching a full score of 33 points.
★★★★★It is called a five-star, with a score of 33-40 points, which means that the probability of serious injury to the occupant is less than or equal to 10%;
★★★★It is called four-star, with a score of 25-32, which means that the probability of serious injury to the occupant is 11%-20%;
★★★It is called a three-star, with a score of 17-24 points, which means that the probability of serious injury to the occupant is 21%-35%;
★★It is called two-star, with a score of 9-16, which means that the probability of serious injury to the occupant is 36%-45%;
★It is called a one-star, with a score of 1-8, which means that the probability of serious injury to the occupant is equal to or greater than 46%;
At the same time, the car crash test not only examines the degree of safety protection for the occupants, but also examines the degree of safety protection for pedestrians. Therefore, in recent years, NCAP has also classified the protection degree of cars to pedestrians as 4 stars: ★★★★ score of 28-36 points, ★★★ score of 19-27 points, ★★ score of 10-18 points, ★ score of 1 -9 points.
Of course, the above classification is only valid for comparisons between cars of the same quality level. Therefore, the premise of NCAP evaluation must be the comparison of collision safety performance between cars of the same quality level, and collision safety between cars of different quality levels. The performance comparison is meaningless.
