Automobile door-opening anti-collision system

Abstract

The invention discloses an automobile door-opening anti-collision system which comprises a measuring instrument, a microprocessor and a warning device, wherein the measuring instrument is used for acquiring touch information of a handle in the door and speed information of an obstacle behind the vehicle; the microprocessor is connected with the measuring instrument and is used for converting an analog signal of the touch information and speed information acquired by the measuring instrument into a digital signal and comparing the digital signal of the speed information with the preset value set in the information and then outputting a warning execution signal; the warning device is connected with the microprocessor and is used for receiving the warning execution signal and starting the warning device. With the adoption of the single-chip technology, under the condition that the automotive inherent device and circuit are not changed, when the vehicle speed is lower than the set value, the rear obstacle speed information is acquired, and when the touch sensor acquires a touch signal, the microprocessor outputs the warning execution signal, passenger safety is ensured by a method of combining double flash, voice prompt, door lock dropping and other manners, and an accident is avoided.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to an automobile door opening anti-collision system. Background technique [0002] At present, vehicle safety is more and more valued by consumers, not only in the protection of drivers and passengers, but also in the protection of people and non-motorized vehicles in the traffic environment, especially because drivers and passengers open the door. When getting out of the car, you don’t pay attention to observe the condition of the car behind you and rush to open the door, causing the electric cars and bicycles driving behind to avoid it in time, causing traffic safety accidents, and even involving life-threatening. [0003] The door opening anti-collision warning system is an active safety technology developed to avoid such accidents. At present, the door opening anti-collision warning system is mainly implemented in two ways: one is to use a visual camera to detect the are...

AI Technical Summary

Problems solved by technology

At present, the door opening anti-collision warning system is mainly implemented in two ways: one is to use a visual camera to detect the area behind the vehicle through visual observation, which has a limited detection distance, poor accuracy and is easily affected by various environmental factors; the other It uses radar technology to detect the area behind the vehicle. This technology has a long detection distance, high precision and is not affected by environmental factors. At present, most of the door opening anti-collision warning systems use frequency-modulated continuous-wave millimeter-wave radar to achieve the relative accuracy of the target. Distance, azimuth angle and speed measurement, but the current control system design of the door opening anti-collision warning system based on radar technology is too complicated, and the control accuracy is poor. In most cases, the anti-collision warning cannot be accurately performed, and the price Higher, less competitive in the market
