Entered BYD’s six-corner building, and the exhibition hall showed a wide range of exhibits, from clouds to Yunba, and then to pure electric buses, but to Xiaobian’s most impressive thing is here. The only exhibition car – BYD Han EV.
For this car, everyone will not feel unfamiliar, this is that BYD sells threatening to kill Tesla Model 3, which can be imagined. I believe that everyone has seen a lot of introduction about its appearance interior. In this small series, there is not much to describe it. Today, come with you, talk about some stories behind this car.
There is such a laboratory in BYD headquarters, and various new cars are placed in the venue, but these new cars are different from us, they are not a window. Crushed, that is, the front of the vehicle or the back is hit, no complete, this is BYD’s waste car.
For example, the front impact of the highest speed of 120 km / tone, offset 25 degrees collision, the side impact of the electric rod and roll test, and these tests will be here. The collision laboratory is completed, every 15 degrees will have a collision test, almost cover all car accident scenarios, some more dangerous tests will move outside the open space, and the vehicles after collision will be scrapped. There is a waste car in BYD. 
Of course, for the real simulation, when a car accident occurs, the number of collisions is still in enough, and it is necessary to collide out the dummy. As the name suggests, this virtual person is used to simulate the impact of the car accident, which is different from the kind of shopping mall. This collision dummy has built-in multi-sensor, and it can be clearly predictable after the car accident.The degree of damage, some of the experimental feedback and the hurt of the real person almost consistent, up to “adult”, “baby”, two to 45 days, different fake people simulate men and women and children’s body, they all have their own The height and the body’s proportion, and their prices are also unpid, it is said to have the most expensive one to reach thousands of RMB.
According to relevant data statistics, there are about 1250,000 people death in road traffic accidents every year. How to reduce the casualty rate of driving passenger and external pedestrians in the accident? Become a problem that everyone needs to overcome it. So, BYD’s car collision test came to life, and this waste car is born for safe.
But only collision is still not enough, in order to further consolidate the safety of the vehicle, strengthen the durability of the body, it also simulates various harsh weather and road conditions, withstand the temperature coverage -40 ° C -80 ° C various scenes Environmental warehouse experiment test, and through the fleet self-driving method, from Hainan, Takeshi to Turpan, etc., the performance of vehicle performance is realized. It is said that the tester is a whitening, and it seems to be a joke, but in fact, it shows the strict test conditions.
Do you think this is it? In many safety tests, the most stringent test is still a “24-channel road simulation test”. The test bench is the use of road simulation test techniques, using axial coupling, and provides 6 in each angle of the passenger car The input of freedom (vertical, horizontal, lateral, outward, steering, braking) can restore 95% of the user who may encounter. BYDA will continue to bump on the gantry for 45 days and night, such a trial should be 3 rounds, which is equivalent to driving over 1 million kilometers from the real car test road, 3 times more than that of most similar models. More.
It can be seen that BYD’s safety and durable test standard is extremely harsh, although these meThey can’t see it, but it is the most important, the road millions, safety first, ask such a thousand hammer, how can consumers don’t like it?
