A few days ago, Zhongbao Research Institute announced the crash test report card of all models since its inception, a total of 85 models, including 56 joint venture cars and 29 domestic cars, the list is as follows. To explain: the car crash results are mainly scored from four aspects: crash resistance and maintenance economy, occupant safety, pedestrian safety outside the car, and vehicle auxiliary safety, G stands for excellent, A stands for good, M stands for general, and P stands for poor.
After seeing this list, many netizens shouted "disobedience", saying how is this possible, we have the impression of "cans", "crispy" Japanese cars, the collision results are so good; and we think that the "thick", "strong" American, German, surprisingly ranked low; and the most respected French car, 25% bias collision, roof strength was only good, the comprehensive results are also very poor, far less than the crispy Japanese car... This is too unfair, it must be recharged by Japanese cars, there must be cat grease, such a list we do not recognize, and so on.
I first state my attitude: I think this crash test list is fair and impartial, there is nothing "catty" or "unspoken rules" or anything like that. The reason is simple: in the same venue, with the same test method, with the same set of evaluation criteria, the evaluation of the results, if not absolutely fair, is relatively fair. This is like the college entrance examination, although it has been criticized by many people, there are imperfect and unfair places of one kind or another, but you must admit that the college entrance examination is the fairest test in China so far, and it is also the fairest way to select talents in China! The talents selected through the college entrance examination are relatively excellent, if not the best, at least much stronger than the vast majority of Chinese people.
So why do so many people question this list? This is mainly because these people have misunderstandings about the safety perception of the car, and they are still stuck in the stage where the car is thick and the impact resistance is good safety. In fact, after more than a hundred years of development, the concept of automobile safety has already formed a mature evaluation system and methods, in general, it is centered on personnel safety, and all other structures and accessories are for this center.
Modern passenger cars basically adopt an energy-absorbing cage-type body structure with front and rear energy absorption and an extremely strong middle crew compartment. The biggest feature of this structure is that the invisible body skeleton (four beams and six columns) hidden inside is the most core safety component, while the outer doors, roof, bumpers, fenders, etc., are only body coverings, which have no effect on the safety performance of the car! It's like a person, whether he is strong and powerful depends on his height, weight, muscles, bones, etc., not on what he wears.
The crash test of modern automobiles is the most important means to evaluate the safety performance of automobiles, and the main evaluation method is to look at the degree of protection of the car for the occupants and laymen in the car, rather than looking at the loss of the car itself, especially those body coverings, which are not in the evaluation system at all. Therefore, you will see some models, the appearance during the collision process is very tragic, but the occupants in the car are safe, such a car safety is good; and some models, after the collision, the appearance may be more complete, but the occupants in the car are seriously injured, so the safety of such a car is not good.
And we ordinary car owners, just these two situations reversed, think that the latter is safe, this is actually a very wrong cognition. The reason for this recognition is related to the education we received when we were young, that property is more important than the people who create property, such as the stories of "Little Sisters of Prairie Heroes" and "Laining Fire Fighting" learned in elementary school, which deeply poisoned us. It hurts to crash the car, and the person who is injured is not too focused. This perception has also created a deformed perception of automobile safety.
Therefore, we must abandon the wrong car safety cognition, abandon the wrong concept of "cars are more important than people", and re-establish the "people-oriented" safety concept. In fact, the safety of the car can be divided into three levels: the outermost layer is the human factor, including human safety awareness, driving technology, safety regulations, etc., in driving to minimize the probability of accidents; the middle layer is the car's active safety performance, including the car's braking system, brake assist system, steering system, etc., when encountering danger, can actively avoid the occurrence of accidents, as far as possible to avoid the occurrence of accidents; the innermost layer is the passive safety of the car, also known as collision safety, including seat belts, airbags, seats, sturdy body, etc. The main thing is to protect the occupants of the car from further injury after the accident and to protect the safety of the occupants as much as possible.
The crash test of China Insurance Research Institute is mainly to evaluate the passive safety performance of the car, that is, the car's ability to protect the occupants after an accident, which is also an internationally accepted automobile safety evaluation method. Japanese cars have good results, mainly because after the collision, the occupant compartment deformation is small, and the occupants in the car are well protected; and the American, German, etc. behind the results, after the collision or A-pillar deformation, or wheel intrusion, will threaten the safety of the occupants in the car, the performance is not good; and the domestic car has made great progress, many models ranked high, especially the tank 300 won the first place, indicating that the domestic car is paying more and more attention to the safety performance of the car; and the Japanese car is not all good, such as Honda's performance is relatively poor, Its body material is relatively poor, which leads to poor body rigidity, and the performance in various collisions is not very good.
In addition, there are many "civil science" type car safety evaluation methods in the society, such as high slope rolling, double car collision, car demolition, etc., which I do not approve of. There are too many accidental factors for high-slope rolling, and can not objectively evaluate the strength of the body, before someone turned the French car from the slope, and then how to say that the car is safe, but in the formal test of the French car safety is not good, especially the A-pillar that affects the strength of the body, the roof, etc., the results are not good; the double-car collision often takes the model that is not the same level, such as the collision between the car and the SUV, it is definitely a car loss, such a conclusion is not universal; and the demolition of the car is now very popular, but the dismantling of the car can only see the material, structure, etc. of the body In the absence of experimental data, it is impossible to determine the safety, such as the same thickness of steel plates, one is ordinary steel, the other is high-strength steel, from the appearance is not visible, but high-strength steel safety is definitely better, and this is dismantling can not be evaluated.
