Does the car deform in the collision test of A pillar , which shows that the car is not safe enough? Recently, the M7 participated in the China Insurance Research Institute test. The test results showed that the three safety indicators of the M7 in the vehicle, the passengers outside the vehicle, and the auxiliary safety of the M7 all reached the highest evaluation of the China Insurance Research Institute G, but the A-pillar deformed during the test. Some people think that the M7 safety does not meet the standards, which is too one-sided.
Faced with many doubts, I think the hardness of the A-pillar cannot be equated with safety. According to relevant tests, after a vehicle collision, A-pillar bending is not an element to measure the body structure rating, but is judged by the intrusion of the upper and lower hinges of the door. Similarly, A-pillar bending is not an element to measure the safety rating of the members in the car, but is known through the sensors on the dummy. Simply put, even if the A-pillar bends after the vehicle is hit, the internal structure of the vehicle is intact, which can still ensure the safety of the driver.
is also important for passive safety such as A-pillar, and active safety is also important. Nowadays, there are few detailed tests on various active safety configurations of cars, which is so unfair to the question-and-anything M7, which has such rich active safety configurations.
Questioning M7 uses the latest braking system of Bosch , and is equipped with sensitive AEB function. With the support of a number of L2+-level assisted driving functions, the active safety configuration is very rich. Just imagine whether a high-speed vehicle does not have a sensitive braking system. Can the A-pillar be used alone to survive a violent impact?
In addition to this, I think the current test has the unity of the environment and test-oriented nature. It is undeniable that the authority and professionalism of the CSI test are, but I still want to raise my questions. The current model is that the test items are fixed and different test models are replaced. In order to obtain a good test score, many car companies add materials and reinforce the test items at the collision position, but ignore the safety protection of other locations. In reality, there is really a collision, and the safety of the entire vehicle depends only on the A-pillar? How to ensure the safety of passengers in co-pilots and passengers in other locations?
In contrast, the main frame structure of the M7 passenger compartment, ultra-high strength steel and high strength steel use account for nearly 60%, with a maximum strength of up to 1500Mpa; at the same time, the whole vehicle is equipped with 8 airbags, including one main airbag, one co-pilot airbag, two front side airbags, two second-row side airbags, and two side air curtains. The co-pilot and rear passengers have taken into consideration. In addition, the M7 of Questioning World has not ignored battery safety and cooperated with the industry's top supplier CATL . The battery pack adopts an array firewall structure. It has to be said that the M7 will consider driving safety very carefully and safety protection is comprehensive.
Also, I want to say that rational thinking is important. Testing is a test after all. The real driving environment is complex and ever-changing. How can you prove that a car with high test scores can guarantee your travel safety? On the contrary, is a car with poor test scores a low safety? It can only be said that models with high collision scores can only reflect that some positions are safe enough to collide under fixed conditions, which does not mean that the overall safety performance of the vehicle is high.
