Abstract
An automatic wiper device of a vehicle is arranged on the vehicle and will activate a wiper when water drips appear on a windscreen of the vehicle. The automatic wiper device comprises an image acquisition device arranged on the windscreen, and an image recognizer arranged inside the vehicle. The image acquisition device focuses on the external side of the windscreen. The image recognizer receives and analyzes an image acquired by the image acquisition device. Moreover, the recognizer will output an activating signal to drive the wiper to act when the recognizer recognizes foggy points in the image, which are caused by water drips. The image acquisition device acquires images at the external side of the windscreen, and the image recognizer judges whether foggy points are caused by water drips and automatically drives the wiper to clear away the foggy points, when water is splashed onto the windscreen in a rainy day. Thus, the cast that the driving safety is be affected as a driver operates the wiper is avoided.
Description
Technical field
The utility model relates to a kind of automatic Wiper system, particularly relates to a kind of automatic Wiper system that is installed on the vehicle and can activates rain brush automatically.
Background technology
General vehicle as runs into that weather is not good to rain in advancing, and raindrop drop in when influence the steerman sight line on the front windshield, mostly is to activate rain brush pivot pendulum in the manually opened mode of steerman, with the raindrop on the removing Windshield.But when vehicle was advanced, steerman need divide heart manipulation rain brush switch, or the steerman of being unfamiliar with vehicle condition also need bow and seek the position of rain brush switch, and situation before the car not to be noted, may influence the safety of driving.
The utility model content
The purpose of this utility model is to provide a kind of automatic Wiper system that can activate the vehicle of rain brush when the rainy day automatically.
The automatic Wiper system of the utility model vehicle is assembled on the described vehicle, described vehicle has Windshield and rain brush, it is characterized in that: Wiper system comprises automatically: be assembled in the video capture device on the described vehicle, and the image identification device that is electrically connected with described video capture device and described rain brush, this image identification device receiving and analyzing video capture device captures the image of above-mentioned Windshield and controls the rain brush start.
The beneficial effects of the utility model are: utilize this video capture device to capture the image of described Windshield lateral surface, distinguish the cloud point that whether has water droplet to cause for the image identification device, with when the rainy day Windshield is spattered with water, automatically drive rain brush and remove, influence traffic safety because of controlling rain brush to avoid steerman.
Description of drawings
Fig. 1 is that the preferred embodiment of the automatic Wiper system of the utility model vehicle is assembled in the structural representation on the vehicle;
Fig. 2 is the block schematic diagram of the preferred embodiment; And
Fig. 3 is the video capture device picked image figure in the preferred embodiment, drops on the Windshield and produces the situation of cloud point with the explanation raindrop.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is elaborated:
As Fig. 1, Fig. 2 and shown in Figure 3, the preferred embodiment of the automatic Wiper system of the utility model is assembled on the described vehicle 2 and activates rain brush motor 22 when cloud point 20 that water droplet causes occurring on the Windshield 21 of described vehicle 2, to drive rain brush 23 pivots pendulum.In the present embodiment, described vehicle 2 is to be that example explains with general automobile, but this vehicle 2 also can be battery-driven car or be the car of power with other energy when implementing.
This automatic Wiper system comprises: be assembled in video capture device 3 on the described Windshield 21, be assembled in the image identification device 4 in the described vehicle 2, and the control power supply is to the rain brush switch 5 of described rain brush motor 22.
This video capture device 3 is video cameras in the present embodiment, and is assembled on Windshield 21 medial surfaces of vehicle 2, and focuses on Windshield 21 lateral surfaces, with the image on acquisition Windshield 21 lateral surfaces.But during actual enforcement, this video capture device 3 also can be assembled on the operator's saddle or instrument carrier panel in the described vehicle 2, only need focal length to focus on the lateral surface in front side Windshield 21, rear side Windshield or skylight etc., all can reach the purpose of pick-up image, so practical range does not exceed with video capture device 3 stack-mounted positions.
These video capture device 3 picked image of these image identification device 4 receiving and analyzings, and whether have the cloud point 20 that produces because of water droplet or raindrop shown in Figure 3 in the identification image.As shown in Figure 1-Figure 3, the image identification device 4 of present embodiment is when the area of cloud point 20 is higher than predetermined value in the unit area in scheduled unit time in the picked image, and this image identification device 4 is just exported and activated signal to this rain brush switch 5.After this rain brush switch 5 received the activation signal of these image identification device 4 outputs, conducting immediately was to connect power supply to described rain brush motor 22, to drive the water droplet on rain brush 23 pivots pendulum removing Windshield 21 lateral surfaces.
Relatively when the area of cloud point 20 was reduced to predetermined value in the unit area in scheduled unit time in the image identification device 4 analysis identification picked image, this image identification device 4 was also exported stop signal to rain brush switch 5.Rain brush switch 5 just opens circuit immediately, makes rain brush 23 stop the pivot pendulum.
That is to say, during vehicle 2 is advanced, when running into front side Windshield 21 and being spattered with water by rainwater or water droplet, this video capture device 3 drives rain brush switch 5 immediately automatically, make the water droplet on the rain brush 23 pivots pendulum removing Windshield 21, do not need steerman to control or look for rain brush switch 5 fully, steerman is the road conditions in the place ahead attentively, improve traveling security.When the rain stopping time, after the cloud point 20 on the described Windshield 21 was removed totally, video capture device 3 also drove automatically immediately and stops described rain brush 23.
Take a broad view of above-mentioned, the automatic Wiper system of the utility model utilizes the image of described Windshield 21 lateral surfaces of these video capture device 3 acquisitions, distinguish the cloud point 20 that whether has water droplet to cause for image identification device 4, with when rainy day Windshield 21 is spattered with water, automatically driving rain brush 23 removes, to avoid steerman to influence traffic safety because of controlling rain brush switch 5, it is very convenient therefore to use, so very practical really and progressive.
