Safety obstacle avoidance system for preventing automobile from falling into water and falling from high altitude based on echo detection and shock absorption method

Abstract

The invention discloses a safety obstacle avoidance system for preventing automobile from falling into water and falling from high altitude based on echo detection. The safety obstacle avoidance system comprises an airbag assembly, an air compressor communicating with the airbag assembly, a plurality of solenoid valves disposed between the airbag assembly and the air compressor, capable of controlling the inflow and outflow of compressed air into and out of the airbag assembly, and adjusting the stiffness of the airbag assembly. An information acquisition module is arranged at the vehicle headposition, and collects water level information when the road surface is filled with water and height information when the road surface is dropped from a certain height. A control module is connectedwith the information acquisition module and the airbag assembly, and used for receiving and analyzing the information sent by the information collecting module and controlling the rigidity of the airbag assembly. A plurality of airbag modules are arranged around a vehicle chassis and a vehicle body, and rapidly inflated when the vehicle is stagnant on a road surface and falling from a high altitude, thereby effectively avoiding danger. The invention also discloses a safety obstacle avoidance method for preventing a vehicle from falling into water and falling from a high altitude based on echodetection.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to an echo detection-based safety obstacle avoidance system and method for preventing automobiles from falling into water and falling from a high altitude. Background technique [0002] In summer, heavy rains are common in many places in my country, bringing a large amount of precipitation, causing water accumulation on the ground, causing losses to people's lives and property safety, and incidents of cars driving into the water and causing casualties, and water damage to vehicles also occur from time to time . In order to prevent this from happening, warning signs are generally set up on these road sections to remind passing vehicles to slow down and the water depth ahead is dangerous. [0003] Although setting up roadblocks and personnel evacuation can reduce accidents to a certain extent, there are still many problems: first, road sections and personnel evacuation will be set up ...

AI Technical Summary

Problems solved by technology

[0003] Although setting up roadblocks and personnel evacuation can reduce accidents to a certain extent, there are still many problems: first, road sections and personnel evacuation will be set up in urban road sections, but there are few suburban and other places, which cannot effectively solve this danger; , when the vehicle encounters a heavy rain during parking, the rainwater will soak into the vehicle and damage the electrical equipment; third, it cannot be timed to remind and obtain rescue after a danger occurs

But some anti-falling safety systems for automobiles that have been designed can open the car door system when entering water, so when the water is deep, they cannot protect the safety of personnel and the damage of the car well, and they are all based on water level sensors, and the trial range is small.
