Millimeter wave detecting vehicle door external anti-collision safety system and protecting method thereof

Abstract

The invention discloses a millimeter wave detecting vehicle door external anti-collision safety system and a protecting method thereof. The safety system comprises an active and passive millimeter wave composite detector, a detecting device, a DSP processor, a triggering device and an emergency unlocking device. The active and passive millimeter wave composite detector is installed on rearview mirrors at two sides, and comprises an antenna device which is installed on the rearview mirrors and faces to the rear. The active and passive millimeter wave composite detector is in singal connection to the triggering device through the detecting device and the DSP processor successively. The safety system is capable of mutually fusing active detection and passive detection, realizing complementaryadvantage, achieving safety and no dead angle through designing a suitable position, and solving a technical problem that a vehicle is started and driven after parking in the case that people open avehicle door without pre-warning and the vehicle door is not closed, and the vehicle easily collides with an outside moved barrier with a heat source.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to a millimeter-wave detection vehicle door exterior anti-collision safety system and a protection method thereof. Background technique [0002] The birth of automobiles has brought various conveniences to human life, and at the same time, car accidents have also brought many disasters and destruction to human beings. In the future, with the development of the economy, the demand for transportation is increasing. According to the statistics of the Traffic Police Bureau, the fatal accidents caused by bad driving habits are as high as 30%. Check whether there are vehicles or pedestrians approaching from behind, causing collisions and scratches between the door and the vehicle that is quickly approaching the door when the door is opened, especially motorcycles and electric bicycles, which are often hit by the door and then fall to the ground and are hit by other passing cars and crush...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a millimeter-wave detection car door anti-collision safety system and its protection method to solve the defects in the prior art that the radiant heat source body cannot be detected and the static high-temperature object close to the car body lacks an identification and alarm function.
