Embodiment 1

[0034] A kind of wiper control system based on driving recorder in this embodiment, as figure 1 As shown, the wiper control system includes a driving recorder and a wiper control unit. It acquires rainwater information through the driving recorder, and then sends a control signal to the wiper control unit, and the wiper control unit controls the working state of the wiper according to the control signal.

[0035] Specifically, the driving recorder is set on the inner side of the windshield of the car, and at the same time needs to be set at the corresponding position of the wiper area of ​​the car, so as to judge the effect of the wiper on the rain.

[0036] The driving recorder analyzes the image of the front windshield of the car, and sends a control signal to the wiper control unit according to the analysis result;

[0037] The wiper control unit controls the working state of the wiper according to the control signal.

[0038] In order to cooperate with the original commu...

Embodiment 2

[0041] What this embodiment provides is a kind of wiper control method based on driving recorder, adopts driving recorder as image acquisition and analysis unit, such as figure 2 As shown, the method includes the following steps:

[0042] Step S10. Continuously collect image information through the driving recorder. The image information can be intercepted from the video information recorded by the driving recorder, or directly control the camera of the driving recorder to obtain the image. After the image of the current windshield is obtained After the information, the feature volume in the image is analyzed.

[0043] In this embodiment, the definition of a feature object refers to an object that often appears on the road, which may be, but not limited to, one or more of people, cars, buildings, trees, and traffic signs. The recognition of these feature objects can be carried out by means of image recognition. In this embodiment, the method of separating a specific object f...

Embodiment 3

[0054] The difference between this embodiment and Embodiment 2 is that it also includes the steps of decelerating and stopping the wiper, such as Figure 4 As shown, the details are as follows

[0055] Step S50: When the number of times of judging that the image information does not meet the rain condition exceeds the first preset value in step S30, the number of judging times is an accumulative process, not a continuous process. That is, when the accumulated number of determinations is greater than the first preset value, a specific interval is added, and step S30 is re-executed. Increasing the specific interval will reduce the frequency of the wiper action.

[0056] If in step S30 it is determined that the number of times that the image information does not meet the rainwater condition exceeds the second preset value, wherein the second preset value is greater than the first preset value, and the number of times of determination is a continuous process, then it can be deter...

Abstract

The invention relates to a windscreen wiper control system based on an automobile data recorder. The windscreen wiper control system comprises the automobile data recorder and a windscreen wiper control part, and automatic control over a windscreen wiper is achieved through image analysis of the automobile data recorder. The invention further provides a windscreen wiper control method. The method comprises the following steps that S10, image information is collected continuously through the automobile data recorder, and characteristic bodies in images are analyzed; S20, compared with preset characteristic data, if the determination condition is met, it is determined that rainwater exists, and a windscreen wiper is controlled to wipe the rainwater; and S30, after a specific time interval, image information is collected again, whether the rainwater existing condition is still met is judged, if yes, the rainwater wiping action is carried out, and meanwhile, the specific time internal is shortened. The windscreen wiper control system and method obtain and analyze the images by being combined with the automobile data recorder, action of the windscreen wiper is controlled according to image identification, the cost is greatly reduced through the system, and meanwhile, the automobile data recording function can be achieved.

Description

technical field [0001] The invention relates to the field of automatic control of automobiles, in particular to a windshield wiper control system based on a driving recorder and a method thereof. Background technique [0002] The wiper is a basic part of the car. Generally, the vehicle is equipped with an ordinary wiper. In rainy days, the driver needs to manually turn it on or off, or manually adjust the different gear speeds of the wiper, which will distract the driver from driving in rainy days. The mental concentration in the car affects driving safety; now some high-end cars are equipped with automatic wipers. In rainy days, the automatic wiper detection module will detect the rain on the window glass to automatically control the opening or closing of the wipers or adjust the rain. The scraping speed brings great convenience to driving in rainy days. [0003] The basic principle of the current automatic wiper: the infrared generating circuit emits infrared rays, and th...
