Embodiment includes all changes, modification and the equivalent fallen into the range of the spirit and intension of attached claims.
The present invention is described below in conjunction with accompanying drawing.
Fig. 1 is the flow chart of the control method of the car door of the embodiment of the present invention.As shown in figure 1, the car of the embodiment of the present invention
The control method of door, comprises the following steps：
S1：After the unlocking signal of car door is received, the positional information and velocity information of object near car door are obtained.
Specifically, after car door is unlocked, it is arranged on after door interlock switch inductor senses door lock open signal at car door, passes through
Environment information acquisition module obtains the positional information and velocity information of object near car door.
In one embodiment of the invention, obtaining car door, nearby the positional information of object and velocity information include：Continuously
The image information at collecting vehicle square object multiple moment behind the door；Image procossing is carried out according to the image information at multiple moment and obtains thing
The velocity information and positional information of body.Further, the image information at multiple moment is after being corresponded to outside car by being arranged on car door
Image acquisition device is installed on visor.
Specifically, environment information acquisition module is to be provided with image collecting device at two exterior mirrors of vehicle,
Preferably high-definition camera.By the image information at image collecting device continuous acquisition car door rear object multiple moment, according to
Multiple moment image informations carry out image procossing, and obtain the positional information and speed of object near car door by graphics principle
Information.Wherein, the object near car door is one or more.Further, the body based on graphics principle sets target object
Product threshold value or height threshold, it is all in when the volume of target object is more than preset vol threshold value and just carries out judgement car into subsequent step
Whether door is safe, or (at least above height of vehicle chassis) just enters subsequently when the height of target object is more than height threshold
Step carries out judging whether car door is safe.
In another embodiment of the present invention, environment information acquisition module is radar, and the position gathered by radar is believed
Breath and velocity information precision are high, and not only for car door rear, to each position object in preset range centered on radar
Positional information and velocity information can gather.
S2：Judge in preset time near car door whether is object according to the positional information of object near car door and velocity information
Into the unlatching track of car door.
In one embodiment of the invention, after what is obtained when carrying out image procossing using image processing apparatus is car door
The positional information and velocity information of square object body, it is then based on positional information, velocity information and the car door and figure of car door rear object
As whether the distance between harvester judgment object enters the unlatching track of car door.In the example of the present invention, preset
Time T is a constant between 5 seconds to 15 seconds, if the distance between target object and image collecting device are S1, object
The speed of body is V, 90 degree of car door open after with the distance between image collecting device be S2If S1>V*T+S2, then thing is judged
Body is introduced into the unlatching track of car door in preset time, if S1≤V*T+S2, then judgment object enter car in preset time
The unlatching track of door.
One embodiment is made in the present invention, when obtaining the positional information and velocity information of object using radar, by
The positional information and velocity information of the object in multiple orientation can be gathered in radar, selects the object towards car door motion to be sentenced
It is disconnected.When judging, assert that car door is in 90 degree of openings, whether target object have passed through car door and be in 90 in preset time
The position of opening is spent, if having passed through the position in preset time, judges that target object enters the rail of car door opening
Mark, if with not entering into the position in preset time, judge that target object is introduced into the track of car door opening.
S3：If object is introduced into the unlatching track of car door near car door in preset time, car door is opened, if default
Object enters the unlatching track of car door near car door in time, then locking car door.
The control method of car door according to embodiments of the present invention, judge whether object can enter near car door before car door opening
Enter car door opening track, opening car door when object will not enter car door opening track near car door, can reduce due to burst
Car door opening cause the probability of traffic accident.
