the number of the moving objects is not limited to 1, and when the number of the moving objects is multiple, the distance information of each moving object relative to the vehicle, the moving direction of each moving object relative to the vehicle and the moving speed information of each moving object relative to the vehicle are respectively determined.
In some embodiments, the identification mode for identifying the moving object can adopt radar identification, the moving object can be directly identified through a radar installed on a vehicle, and the distance information of the moving object relative to the vehicle, the moving direction of the moving object and the moving speed information of the moving object are calculated. In some embodiments, the identification mode for identifying the moving object may be image identification, and the distance information of the moving object relative to the vehicle, the moving direction of the moving object, and the moving speed information of the moving object may be identified and calculated by collecting the video information around the vehicle through a video device installed in the vehicle and performing graphic analysis on the multi-frame image in the video information.
Step 101 may be performed in real time, but is not limited thereto, and may be started only as needed to save vehicle system resources.
102. And controlling the vehicle door lock according to the distance information, the movement direction and the movement speed information.
The automobile door lock is characterized in that automobile doors are respectively installed on two sides of an automobile, each automobile door corresponds to a door lock, and the door locks are used for controlling the openable state of the automobile doors. The vehicle door lock can be controlled to be in a locking state and an unlocking state respectively, and when the vehicle door lock is in the locking state, the vehicle door cannot be opened; when the vehicle door lock is in an unlocked state, the vehicle door can be opened, the mode of opening the vehicle door is determined according to the self structure of different vehicles, and the vehicle door can be opened through a handle of the vehicle door.
In implementation, a comparison condition can be preset, the distance information relative to the vehicle, the moving direction of the moving object, the moving speed information of the moving object and the preset comparison condition are compared, and the vehicle door lock is controlled to be switched to a locking state or an unlocking state according to a comparison result.
According to the control method of the vehicle door lock, the moving object in the preset monitoring area around the vehicle can be identified, the vehicle door lock can be controlled through the distance information of the moving object relative to the vehicle, the moving direction of the moving object and the moving speed information of the moving object, when a person in the vehicle opens the vehicle door, if the dangerous moving object is identified, the vehicle door lock can be controlled, the vehicle door is prevented from being opened, the moving object is prevented from colliding with the opened vehicle door, and compared with the prior art, collision accidents in the vehicle door opening process of the person in the vehicle can be reduced.
Specifically, in some embodiments, the comparison condition may include, but is not limited to, comparing distance information and comparing movement speed information, and controlling the vehicle door lock to be in the locked state when the distance information is less than the comparison distance information or the movement speed information is greater than the comparison movement speed information.
For example, specifically, as shown in fig. 2, in some embodiments, the comparison condition may include a preset distance and a preset time for opening the door, and step 102 may include:
1021. if the moving direction faces the vehicle, calculating the time for the moving object to reach the preset distance from the current position to the vehicle according to the distance information and the moving speed information;
when the distance information is used as s1Indicating, for example, the speed of movement information by v1Showing that the preset distance is L and the movement time is t1When indicating, the exercise time is t1The specific calculation formula of (2) may be: t is t1＝(s1-L)/v1(ii) a The preset distance L is a preset safety distance, and the number of the preset safety distances may be 1 or more, each preset safety distance corresponds to different movement speed information, and the preset safety distance increases with the increase of the movement speed information.
1022. Judging the sizes of the exercise time and the preset vehicle door opening time;
the preset time for opening the vehicle door can be an empirical value, and is obtained through a preset door opening test, but the preset time is not limited to this.
1023. And if the time spent in the movement is less than or equal to the time spent in the opening of the vehicle door for presetting, controlling the vehicle door lock to be in a locking state.
Compared with the embodiment that the comparison conditions comprise preset comparison distance information and comparison movement speed information, more accurate control can be realized aiming at the door opening time of different vehicles in the embodiment, namely, the method is applicable to more vehicle types and only needs to measure the opening time of the vehicle door of the vehicle type to different vehicle types for presetting time.
Further, in order to remind the vehicle interior personnel that the door lock of the vehicle is in a locked state, the method can further comprise a step 1024 of playing a locking prompt tone if the time of the motion is less than or equal to the time of the preset vehicle door opening time. The audio form of the locking prompt tone is not limited, and the locking prompt tone can be voice information, or can be a sound such as music for realizing a prompt function.
In a specific implementation, after there is no dangerous moving object around the vehicle, the vehicle door lock needs to be unlocked, and in some embodiments, after step 1024, the locking control of the vehicle door lock may be released. Namely, after the personnel in the vehicle receive the locking prompt tone, the personnel in the vehicle know that dangerous moving objects exist around the vehicle, then the door lock of the vehicle is unlocked, the personnel in the vehicle can observe the surrounding environment condition by oneself, and the door can be opened after the surrounding environment of the vehicle is considered safe.
In some other embodiments, after step 1023 or step 1024, the method further includes the steps of:
and when the movement time of all moving objects in the preset monitoring area around the vehicle is greater than the preset time for opening the vehicle door, releasing the locking control of the vehicle door lock.
Namely, after the vehicle judges that the surrounding environment is safe, the vehicle door lock is unlocked by itself, so that the vehicle door can be opened directly without the need of the personnel in the vehicle to watch whether the surrounding environment is safe again.
