Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a flowchart illustrating a method of cleaning a windshield according to an exemplary embodiment to solve a technical problem in the related art that a safety-related dead angle of a field of view is caused by a limited cleaning range of a wiper blade. As shown in fig. 1 and 2, the method for cleaning a windshield glass of the present embodiment is applied to a vehicle including a main wiper 10 and a sub wiper 20 at a lower edge and an upper edge of the windshield glass 30, respectively, and includes the steps of:
and S11, acquiring the rain amount value outside the windshield 30.
And S12, confirming the corresponding threshold range of the rain amount value.
And S13, controlling the working states of the main wiper 10 and the auxiliary wiper 20 according to the corresponding threshold value range.
In the present embodiment, the method for cleaning the windshield glass 30 is applied to a vehicle comprising two wipers, referring to fig. 2, the main wiper 10 is disposed at the lower edge of the windshield glass 30, and the auxiliary wiper 20 is disposed at the corner of the upper edge of the windshield glass 30.
As shown in fig. 2, the main wiper 10 includes a wiper motor 11, a wiper link 12 connected to the wiper motor 11, a wiper arm 13 connected to the wiper link 12, and a wiper blade 14 connected to the wiper arm 13. After the wiper motor 11 is started, the wiper connecting rod 12 is driven to move back and forth transversely, and then the wiper connecting rod 12 drives the wiper rod 13 to swing back and forth, so that the wiper blade 14 makes a fan-shaped motion on the windshield 30 as shown by an arrow. In fig. 2, it is obvious that the wiping area of the main wiper 10 cannot cover the whole windshield 30, and a non-wiping area exists in the upper left corner area of the windshield 30, and the non-wiping area is likely to form a dead angle of a visual field, resulting in a certain potential safety hazard.
In order to solve the above problems, it is necessary to provide the sub wiper 20 at the upper edge of the window glass 30 of the vehicle, that is, the sub wiper 20 is provided at the non-wiping area, and alternatively, the sub wiper 20 may be provided at both left and right upper intersections of the window glass 30. Then, step S11 is executed to obtain the rain amount value outside the windshield 30. A rain sensor may be disposed outside the windshield 30, and then a rain value outside the windshield 30 may be obtained by the rain sensor.
After acquiring the rain amount value outside the windshield 30, step S12 is executed to confirm the threshold range corresponding to the rain amount value. The threshold range may be set by a technician according to the vehicle, and the disclosure is not particularly limited thereto. After confirming the threshold range corresponding to the rain amount value, step S13 is executed to control the operating states of the main wiper 10 and the sub wiper 20 according to the corresponding threshold range.
For example, when the rain amount value is less than or equal to a first threshold value, only the main wiper 10 is turned on. That is, when the amount of rain is small, the main wiper 10 is controlled to operate to clean the windshield glass 30 without opening the sub wiper 20. When the rainfall value is larger than the first threshold and smaller than the second threshold, the main wiper 10 and the auxiliary wiper 20 are started, and the oscillating frequency of the auxiliary wiper 20 is controlled to be lower than the oscillating frequency of the main wiper 10. That is, when the amount of rain is moderate, the main wiper 10 and the sub wiper 20 operate simultaneously, but since the amount of rain is not so large, the oscillating frequency of the sub wiper 20 can be controlled to be lower than that of the main wiper 10, thereby saving energy consumption. And when the rainfall value is greater than or equal to a second threshold value, starting the main wiper 10 and the auxiliary wiper 20, and controlling the oscillating frequency of the auxiliary wiper 20 to be the same as the oscillating frequency of the main wiper 10. That is, when the amount of rain is large, the main wiper 10 and the sub wiper 20 operate simultaneously, and the oscillating frequency of the sub wiper 20 is controlled to be the same as that of the main wiper 10.
This is disclosed through set up two windscreen wipers outside windscreen, and then has increased the area of clean windscreen to according to the outside rainfall value of windscreen, through control the operating condition of main windscreen wiper with vice windscreen wiper is with the adaptation rainfall size, and furthest improves windscreen's field of vision definition, has solved the limited technical problem that leads to there being the field of vision dead angle of potential safety hazard in the clear scope of wiper blade among the correlation technique.
