Embodiment 1

[0027] A security strategy system based on blind spot detection, comprising: a distance detection module, a speed detection module, a vehicle door locking module, and a processing module. The distance detection module includes a front distance detection module and a rear distance detection module. The detection direction of the head distance detection module is towards the head of the car, so as to detect the dynamic obstacles in the direction of the head of the car in real time, so as to detect the distance between the dynamic obstacle and the head of the car to obtain the distance parameter of the head of the car. The detection direction of the parking space distance detection module is towards the rear of the vehicle, so as to detect the dynamic obstacles in the direction of the rear of the vehicle in real time, so as to detect the distance between the dynamic obstacles and the parking spaces to obtain the distance parameters of the vehicle rear. The speed detection module ...

Embodiment 2

[0034] A security policy method based on blind spot detection is realized by the system described in the first embodiment. The method includes the following steps: Step 1: detect the distance between the vehicle body and the dynamic obstacle in real time to obtain the distance parameter, and detect the moving speed of the obstacle in real time to obtain the speed parameter;

[0035] Step 2: Calculate the movement distance parameters according to the predetermined duration and speed parameters;

[0036] Step 3: Compare the movement distance parameter with the distance parameter to obtain the comparison result;

[0037] Step 4: Lock the door when the comparison result is that the movement distance parameter is greater than the distance parameter.

[0038] When executed in real time, the distance parameters include the front distance parameter and the rear distance parameter. When the dynamic obstacle at the front of the vehicle moves towards the vehicle body, the distance betw...

Abstract

The invention relates to the technical field of automobiles, in particular to a safety strategy system based on blind area monitoring. The system comprises a distance detection module, a speed detection module, a vehicle door locking module and a processing module, wherein the distance detection module is used for detecting the distance between a vehicle body and an obstacle in real time to obtain a distance parameter; the speed detection module is used for detecting the movement speed of the obstacle in real time to obtain a speed parameter; a preset duration is stored in the processing module; the processing module is used for calculating a motion distance parameter according to the preset duration and the speed parameter; the processing module is used for comparing the motion distance parameter with the distance parameter to obtain a comparison result; and the vehicle door locking module is used for locking a vehicle door when the comparison result is that the movement distance parameter is greater than the distance parameter. In the prior art, the accident that the vehicle door collides with other vehicles due to mistaken opening of the vehicle door is likely to happen. Compared with the prior art, the obstacles in the blind area can be effectively detected, so that the vehicle door is locked in time, and the safety is effectively improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a safety strategy system and method based on blind spot monitoring. Background technique [0002] With the continuous development of technology, cars have gradually entered people's daily life, so how to ensure the driving safety of cars and reduce traffic injuries has become a very important social issue at present. [0003] When people in the car want to get out of the car, it often happens that the people in the car fail to notice other vehicles or pedestrians near the vehicle and open the door by mistake, causing other vehicles or pedestrians to fail to dodge the door in time and cause serious traffic safety accidents . Therefore, when the vehicle is parked, how to effectively detect the obstacles around the vehicle and limit the opening of the door in time has become a very important issue. Contents of the invention [0004] Aiming at the technical problems of the pr...
