Intelligent automobile door lock system based on computer vision

Abstract

The invention discloses an intelligent automobile door lock system based on computer vision, which is used for reducing the occurrence of accidents that passengers in an automobile suddenly open an automobile door to knock down an automobile coming from the back, and comprises the following steps of: 1) the running speed of the automobile is acquired, and when the automobile speed is lower than acertain value, the system is enabled to enter a standby state; 2) the passenger unbuckles a safety belt, and the system works officially; (3) when a camera monitors that the moped approaches and is dangerous enough, a vehicle-mounted microcomputer drives a door lock motor to lock the automobile door, and an indicator lamp in the automobile flickers; 4) if misjudgment occurs, the passenger in the automobile can forcibly open the automobile door by toggling a mechanical unlocking switch or a double-pull inward-opening handle; (5) after the moped is far away and no new moped appears, the vehicle-mounted microcomputer drives the door lock motor to unlock the automobile door, and (6) the passenger in the automobile pulls the inward-opening handle, a prompt lamp outside the automobile flickers,the passenger gets off the automobile and closes the door, and the system is shut down. The monitoring distance is long, the accuracy is high, and the upgradable space is large.

Description

technical field [0001] The invention relates to an active intervention system for electric car door locks of automobiles, belonging to the technical field of auto parts. Background technique [0002] As the number of cars increases, roads become more and more congested. Therefore, when cars are parked on the side of the road, motorcycles / electric vehicles / bicycles pass by next to the cars. If the passengers in the car rashly open the door without carefully observing the situation outside the car, it will lead to dangerous situations, ranging from damage to vehicles, to serious casualties, and such phenomena can be greatly reduced through technology. After an online survey, the German kiekert company proposed to use the ultrasonic principle to monitor whether there is a moving object approaching behind the car. If there is a moving object approaching, the system will force the door to be locked. However, the defects of this method are obvious. First, the speed of sound propa...

AI Technical Summary

Problems solved by technology

However, the defects of this method are obvious. First, the speed of sound propagation is slow and the response is not sensitive. Second, the area of ​​interest cannot be selected, and the misjudgment rate is high. Third, the upgradeable space is small, and it is impossible to further identify whether it is a bicycle or a motorcycle.
