Vehicle collision buffering system and method

Abstract

The invention discloses a vehicle collision buffering system and method. The system comprises a distance sensor, a vehicle body control module, an intelligent control switch and a foam generator device, wherein the foam generator device comprises a front nozzle, a rear nozzle, a front storage tank, a rear storage tank and a connecting pipeline; the plurality of nozzles are arranged, so that the ejected foam materials are uniformly distributed from the front / rear bumper area to a vehicle width boundary; the distance between the vehicle and the obstacle is collected by the distance sensor; the vehicle body control module collects speed information and determines the minimum braking distance, and when the distance between the vehicle and the obstacle is judged to be smaller than the minimum braking distance, the intelligent control switch is controlled to open the foam generator device; and the foam generator device is used for preparing the foam material, and the foam material is sprayedon the front surface of the vehicle or the rear surface of the vehicle. The system further comprises a central control display screen, and the system can also inject an oil film. According to the scheme, the collision energy is effectively absorbed, the impact strength during accidents is reduced, and the driving safety is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle collision buffer system and method. Background technique [0002] At present, the number of vehicles in the society is high, the vehicle traffic is heavy, and traffic accidents occur from time to time. Although the existing braking technology can reduce the damage of traffic accidents to a certain extent, in rainy and snowy weather, due to the change of the friction coefficient between the road surface and the tires, the braking function decreases, and traffic accidents still occur, causing personal and property damage. In addition, brake failure and speeding will also cause traffic accidents and cause serious losses. [0003] Chinese patent document CN 204020790 U discloses a device for an external airbag of an automobile, which controls the ejection of the external airbag when a collision is about to occur or when a collision is occurring. Chinese patent documen...

AI Technical Summary

Problems solved by technology

For the airbag, it needs to be replaced once used; for the built-in energy absorbing device, it cannot be flexibly installed on the surface of the whole vehicle
