A method for protecting human-earth collision damage of high-speed cars

Abstract

Aiming at the existing achievements that protect people from collision damage only by preventing the separation of people and vehicles from the front of the vehicle, the present invention proposes to catch pedestrians from the rear of the vehicle by moving the vehicle and supplemented by an inverted U-shaped bag-shaped airbag installed on the rear edge of the vehicle roof. Ways to prevent man-earth collisions. When the high-speed car detects that a vehicle-person collision accident is inevitable, it will brake completely until the head collides with the car body; then control the vehicle so that the front edge of the roof and the human body keep a certain distance and move forward at the same time; when it is detected that the human body is higher than the roof When the airbag is detected, the airbag is detonated and the vehicle is controlled to keep the front edge of the rear window glass at a certain distance from the human body while moving forward; when it is detected that the human body is in contact with the airbag, it starts to brake completely until the vehicle stops. The invention controls the vehicle and uses the airbag to catch the falling human body, so as to reduce the impact force on the human body in the horizontal and vertical directions at the time of catching, and the airbag wraps the human body to completely prevent the human body from colliding with the ground, so as to protect the high-speed impact People under the ground collision damage.

Description

technical field [0001] The invention relates to the field of pedestrian protection, more specifically, to a method for protecting people from collision damage of high-speed cars. Background technique [0002] Vehicle-person collision accidents have drawn public attention because they are closely related to everyone's daily life. Compared with the occupants in the car, pedestrians are more likely to be fatally injured in an accident due to the impact of the hard car body. The injury of the human body in a vehicle-person collision accident mainly comes from the first impact with the vehicle body and the second impact with the ground afterwards. Existing studies have shown that no matter at high speed or low speed, the human body injury caused by vehicle body impact is more serious, but the ground impact at low speed cannot be ignored. More studies have found that when the vehicle speed is lower than 40km / h, if the ground impact damage can be avoided, the total injury suffere...

AI Technical Summary

Problems solved by technology

However, under high-speed impact, the human body will obtain a large speed obliquely upward from the car body. In this case, it may be difficult to protect pedestrians by forcibly sticking to the human body or only through the front airbag, and more human body protection is needed. Program
