·Car collision requires more "grounding gas" rating

Recently, the two ninth-generation Accord of Guangzhou Automobile Honda collided at a speed of 56 kilometers per hour at a 15° angle of inclination with a 25% overlap. This collision has not only become the first high-speed collision of small vehicles in the car, but also for China. Car safety testing has opened a new page.
On the surface, this collision is nominally the same as the 25% overlap rate collision test in the C-NCAP, which is dominated by the China Automotive Technology and Research Center. However, the addition of “car-to-car” and “15° bevel”, Make it the "most demanding" crash test in history.
Car-to-vehicle collision is the most common form of traffic accident in real life, and most of the current collision tests are in the form of car-to-obstacle. Compared with the vehicle-to-obstacle collision test, in the collision of the vehicle, the absorption and dispersion of the collision energy is more complicated than the collision of the obstacle material with uniform material, and the local structure and the unevenness of the hardness of the part are generated. If the concentrated impact of the area cannot be effectively dispersed, the deformation of the passenger compartment will increase, and the impact on the occupant will also increase. Therefore, the collision between the vehicle and the vehicle is stricter on the safety of the vehicle, and the safety level of the vehicle can be tested. At the same time, the 15° bevel angle is closer to reality than the traditional frontal collision form due to the driver's instinctive avoidance of the vehicle tilt caused by the actual accident, which can truly test the safety performance of the vehicle.
In fact, from the car-to-vehicle to small overlap rate crash test, in recent years, similar humanized scoring projects have become more and more in the C-NCAP crash test, which is more in line with real life. For example, many auto manufacturers are currently exerting their power on active safety devices. The C-NCAP collision standard is listed as an important plus item in a timely manner to encourage the promotion of ESC devices. In the future, the C-NCAP collision standard is expected to include pedestrian protection devices, car rear-mounted commercial vehicle protection devices, and new energy vehicle battery safety, leakage protection, and fire risk into the 2018 version of the evaluation standard.
It should be said that the previous collision test projects such as frontal and side collisions can no longer meet the potential safety risks caused by the increasingly complex vehicle environment. Keeping pace with the times and complying with the actual situation in China is the most necessary C. -NCAP.
