I don’t know if it is a coincidence. I have just announced the latest round of collision results, “C-NCAP” and Peugeot will announce the 508L “domestic public full load high-speed bidirectional side collision. test”. Since there is so much attribute in the side of the Peugeot 508L, it is known as “the first time in China”, naturally, it will expose some 508L not known safety while attracting attention!
For contemporary cars, responsible for the safety of members in the car is mainly divided into two major items for active security and passive safety. Among them, the AEB active brake, the ESP vehicle stabilization system is “active safety”. After all, if you want to guarantee absolute safety on your way, you don’t have an accident. It is obviously the best solution, and the role of ESP and AEB is just right to avoid accidents. 
When the vehicle body structure is designed, the amount of heat forming steel is represented by the number of airbags is “passive”. After all, “often in the river, how to have no wet shoes”, the active safety configuration can reduce the possibility of the accident, but it does not guarantee that other drivers don’t hit you, so I can protect the occupants at this time. The “passive safety” system of life is highlighted.
Generally, the most common accident is to be a positive collision. At the same time, due to the front collision, the speed of the speed is very fast, so a positive collision is not only common, but also more dangerous. Because of this, whether Europe’s E-NCAP or the US IIHS or domestic C-Iasi has made strict test standards for positive collisions, such as 100%, 40%, or even 25% difficult collision.

Because of this, whether Europe’s E-NCAP or the US IIHS or domestic C-Iasi has made strict test criteria for positive collisions, such as positive100%, 40 percent, or even 25% of the 25% of the difficulty.
The side of the vehicle is not the case. Due to the lack of protection like the head engine compartment and the vehicle strip, the collision optimization of the vehicle enterprise is often very difficult. After all, it is compared to long engine compasses that there is only a B-column and the anti-collision beam of the door inside the vehicle side. Therefore, all major vehicle safety collision mechanisms around the world will also collide with the side of the vehicle to verify that the vehicle has encountered the protection capabilities of the vehicle after the side collision.
Vehicle stationary side collision 
In the side collision test of the vehicle, the general safety mechanism will test the test vehicle to wait for the crash. That is to say, only the trolley responsible for impact in the collision test is moving. By this to simulate the damage to the personnel in the car when the vehicle is stopped.
Column tissue test 
In addition to the passive side, it is easiest to cause a “column touch”, which is the “column touch”, which is to make the side of the vehicle. A rigid column is hit by a speed, simulating a scene of the rods and barriers such as electric wires, trees such as electric wires, trees. The “column tissue” test is very difficult to specifically optimize the “column tissue” due to the uncertainty of the power area and the collision position. At present, in the latest E-NCAP test, it has a “column touch” test with 32km / h to test the safety of the vehicle. However, due to the probability of “column touch”, there is no other agency in this test in addition to European NCAP, Australia NCAP and South Korea NCAP.
Taking into account that the side touches in the collision industry is not rare, why is this Peugeot 508L to challenge? Bidirectional side collision test “? In fact, this is mainly because 508L this collision condition is different than the general C-NCAP side collision test.
C-NACP Conventional Side Touch
Touching the C-NACP Conventional SideIn the tester, a trolley with a weight of 1300kg is a tape of the test vehicle at a speed of 50km / h. The speed of this Peugeot 508L was raised to 55km / h. Everyone can don’t underestimate the speed of this 5km / h, because this seemingly inconspicuous 5km / h will make the collision kinetic energy of the crashing car directly increased from 151.72 kg.
At the same time, it is different from the original stationary waiting. This time 508L will travel forward in the crash during the collision, which can be the largest. The degree simulates the collision environment of the real crossroads.
Further, 508L also simulates a four-port scene in the collision test. Among them, the main driving is an adult male dummy, and the co-driver is a fake person in adult. On the left side of the rear seat of the vehicle, a 10-year-old children’s dummy that can not use the safety seat, the right side is 6 years old and the use of safety seats.
As can be seen in the figure above, at the moment of the 208L side, the B-column of the vehicle and the anti-collision beam in the door will become inside the protection vehicle. The first one of the members is also the largest barrier. Although after the impact, the 508L back door appeared outward, but the door did not be hit, and successfully avoided the case of the car within the car to cause secondary injuries.
At the same time, at the moment of collision, the roof structure of the vehicle did not have any deformation or breakage. After all, 508L panoramic sunroof state is very complete, and there is no significant deformation in the A column and the B column.
The situation in the car is equally optimistic, 508L side gas curtains and side airbags are very accurately composed of adult male dummy’s body, avoiding their appearance with the body. Hard hard. At the same time, the main driving of the airbag has no explosion, avoiding additional injuries and money losses in the driver. 
Compared to the double protection of the front row with side airbags and air curtains, “children” on the left side of the rear row can only rely on the side gas curtains before and after running. Good at 508L second exhaust curtain has more design of the airborne air. In an instant, the head of the second row of passengers will first contact more thick curtains, and maximize the head harness.
At the same time, at the moment of the collision, the 508L automatic lock system detected a drastic collision, and then opened the right side, the rear door Door locks, convenient in the car, escaping and the rescue of the external rescue personnel. In the end, the C-NCAP gathered in the side of the 508L of the car to protect the score of 88.75 percentage in the side of the 88.75 percentage of the car, and the evaluation level was excellent.
Although China’s 508L and E-NCAP in 2018 have been different in 2018, there are some different countries. In general, whether 508L or Europe’s 508 in Europe has achieved excellent rating for the protection of members in the car, even the side collisions and “column touch” of the European regulation 508 have achieved full scores. This can be seen that overseas 508 and China 508L have a great effort on collision test.
When I check out the European collision mechanism E-NCAP official website, I also found some differences. For example, the 2020 E-NCAP side touched the trolley speed from the original 50km / h to 60km / h, and the current domestic energy is still 50km / h, and the kinetic energy gap between the two can be imagined. I hope that I hope that China is also Can improve the collision test standard as soon as possible.
Further, compared to “column touch” testing over the overseas, China is still a blank, according to the rules of C-NCAP2021, only only The new energy model increases 32km / h column tissue test to test whether the battery is safe after collision, and traditional fuel models will not perform “column touch”.
While this 508L “domestic public full load high-speed bidirectional side collision test” did create a primary river in China, but finally 508L can achieve such a high score, except for its own excellent side protection In addition, the test in the car is also used by seat belts, children’s seats to protect their own safety. Therefore, relative to the safety belt, it is not a seat belt, holding the child sitting in front, giving the seat sleeve, causing the side airbags that can not explode these bad habits, is to let the domestic car accident rate of 10 years of the world’s first Culprit!
