In the application, the wiper may be a hidden wiper or a non-hidden wiper. Illustratively, the wiper is described as a hidden wiper.
According to the control method of the windscreen wiper, provided by the embodiment of the application, the comparison information on the surface of the front windscreen of the vehicle is obtained, wherein the comparison information comprises the running speed of the vehicle, the infrared light intensity on the surface of the front windscreen and the environment temperature; comparing the comparison information with a preset threshold value to obtain a comparison result; and controlling the movement speed of the windscreen wiper according to the comparison result. Therefore, the control method can combine the running speed of the vehicle, the infrared light intensity on the surface of the front windshield and the ambient temperature to reduce the interference of the running speed and the ambient temperature on the acquisition of the infrared light intensity, so that the control method can accurately control the movement speed of the windscreen wiper.
In the embodiment of the application, the running speed of the vehicle can change the rainfall on the surface of the front windshield, and the rainfall can change the infrared light intensity on the surface of the front windshield, so that the accurate control of the movement speed of the windscreen wiper is affected. In order to accurately control the movement speed of the windscreen wiper, a proper preset infrared light intensity threshold value is matched according to the running speed and is compared with the infrared light intensity on the surface of the front windshield, so that a comparison result is more reliable.

s200, comparing the running speed of the vehicle with a preset speed threshold value to obtain a first comparison result;
s210, comparing the infrared light intensity on the surface of the front windshield with a preset infrared light intensity threshold according to the first comparison result to obtain a second comparison result.

For example, the preset speed threshold of the passenger car may be set to 80km/h. In this way, the appropriate preset infrared light intensity threshold value can be set according to the first comparison result, so that the second comparison result obtained by comparing the infrared light intensity on the surface of the front windshield with the appropriate preset infrared light intensity threshold value can be more reliable.

and S230, when the running speed is greater than or equal to a preset speed threshold, comparing the infrared light intensity on the surface of the front windshield with a second preset infrared light intensity threshold to obtain a fourth comparison result.
Further, referring to fig. 4, in some embodiments of the present application, controlling the movement speed of the wiper according to the third comparison result includes:

s2230, when the infrared light intensity on the surface of the front windshield is smaller than a third infrared light intensity threshold value, controlling the wiper to run in a third movement speed mode;
s2240, when the infrared light intensity on the surface of the front windshield is smaller than a fourth infrared light intensity threshold value, controlling the wiper to run in a fourth movement speed mode;
the second infrared light intensity threshold is between the first infrared light intensity threshold and the third infrared light intensity threshold, the third infrared light intensity threshold is between the second infrared light intensity threshold and the fourth infrared light intensity threshold, and the first infrared light intensity threshold is greater than the fourth infrared light intensity threshold.
In the embodiment of the application, the first infrared light intensity threshold is smaller than the infrared light intensity in the absence of rain in the sunlight, so that the influence of infrared light components in the ambient light can be reduced, and the reliability of comparison is further improved. In addition, when the infrared light intensity on the front windshield surface is smaller than the first infrared light intensity threshold, that is, the rainfall on the front windshield surface is the precipitation of light rain (usually, the precipitation is smaller than 5mm in 12 hours or smaller than 10mm in 24 hours), the wiper is controlled to operate in a first movement speed mode, which can be understood as a low speed mode (the wiper goes back and forth 15 times/min on the whole surface of the front windshield); when the infrared light intensity on the front windshield surface is smaller than a second infrared light intensity threshold value, namely the rainfall on the front windshield surface is the precipitation of medium rain (precipitation of 5mm-15mm in 12h or precipitation of 10mm-25mm in 24 h), the windscreen wiper is controlled to operate in a first movement speed mode, and the second movement speed mode can be understood as a medium speed mode (the windscreen wiper moves back and forth for 30 times/min on the whole surface of the front windshield); when the infrared light intensity on the front windshield surface is smaller than a third infrared light intensity threshold value, namely the rainfall on the front windshield surface is the precipitation of heavy rain (precipitation of 15mm-30mm in 12h or precipitation of 25mm-50mm in 24 h), the windscreen wiper is controlled to operate in a third movement speed mode, and the third movement speed mode can be understood as a high speed mode (the windscreen wiper moves back and forth 60 times/min on the whole surface of the front windshield); when the infrared light intensity on the front windshield surface is smaller than the fourth infrared light intensity threshold, that is, the rainfall on the front windshield surface is the precipitation of heavy rain (precipitation is greater than or equal to 30mm in 12h or greater than or equal to 50mm in 24 h), the wiper is controlled to operate in a fourth movement speed mode, and the fourth movement speed mode can be understood as an ultra-high speed mode (the wiper moves back and forth 90 times/min on the whole surface of the front windshield).
In the above embodiments, on the premise that the running speed is smaller than the preset speed threshold, the infrared light intensity on the front windshield surface is compared with different infrared light intensity thresholds respectively, so that the wiper can be accurately controlled to have a proper running speed.
Referring to fig. 5, in some embodiments of the present application, controlling a movement speed of a wiper according to a fourth comparison result includes:
s2300, controlling the wiper to run in a fifth movement speed mode when the infrared light intensity on the surface of the front windshield is smaller than a fifth infrared light intensity threshold value;

s2320, controlling the wiper to run in a seventh movement speed mode when the infrared light intensity on the surface of the front windshield is smaller than a seventh infrared light intensity threshold value;
wherein the sixth infrared light intensity threshold is between the fifth infrared light intensity threshold and the seventh infrared light intensity threshold.
When the infrared light intensity on the front windshield surface is smaller than the fifth infrared light intensity threshold value, namely, the rainfall on the front windshield surface is the precipitation of small rain (usually, the precipitation is smaller than 5mm in 12h or smaller than 10mm in 24 h), the windscreen wiper is controlled to operate in a fifth movement speed mode, and the first movement speed mode can be understood as a medium speed mode (the windscreen wiper moves back and forth for 30 times/min on the whole surface of the front windshield); when the infrared light intensity on the front windshield surface is smaller than a sixth infrared light intensity threshold, namely the rainfall on the front windshield surface is the precipitation of medium rain (precipitation of 5mm-15mm in 12h or precipitation of 10mm-25mm in 24 h), controlling the wiper to operate in a sixth movement speed mode, wherein the sixth movement speed mode can be understood as a high speed mode (the wiper makes a round trip for 90 times/min on the whole surface of the front windshield); when the infrared light intensity on the front windshield surface is smaller than the seventh infrared light intensity threshold, that is, the rainfall on the front windshield surface is greater than or equal to 15mm in 12h or greater than or equal to 25mm in 24h, the wiper is controlled to operate in a seventh movement speed mode, and the seventh movement speed mode can be understood as an ultra-high speed mode (the wiper reciprocates 90 times/min on the whole surface of the front windshield).
In the above embodiments, on the premise that the running speed is greater than or equal to the preset speed threshold, the infrared light intensity on the front windshield surface is compared with different infrared light intensity thresholds, respectively, so that the wiper can be accurately controlled to have a proper running speed.
Referring to fig. 6, in some embodiments of the present application, when the intensity of infrared light on the front windshield is less than a second threshold value of infrared light intensity, the wiper is controlled to operate in a second movement speed mode; or when the infrared light intensity on the front windshield surface is smaller than the sixth infrared light intensity threshold value, controlling the wiper to run in the sixth movement speed mode further comprises:

In the above embodiments, the damage of the infrared sensor can be found in time through the above steps.
Further, referring to fig. 7, in some embodiments of the present application, comparing magnitudes between a plurality of infrared light intensities to obtain a fifth comparison result includes:
s2421, when a plurality of infrared light intensities sequentially decrease according to the acquisition sequence, controlling the windscreen wiper to enter a first movement speed mode;
s2423, when the plurality of infrared light intensities are not sequentially reduced but the same according to the acquisition sequence, entering into a step S2430;
s2425, when the plurality of infrared light intensities are not sequentially reduced but are different according to the acquisition sequence, prompting that the infrared sensor is abnormal.
Referring to fig. 8, in some embodiments of the present application, the method further includes:
s2440, comparing the ambient temperature with a preset temperature threshold when the acquired infrared light intensities are normal;
s2450, controlling the wiper to run in a first movement speed mode or a fifth movement speed mode when the ambient temperature is less than or equal to a preset temperature threshold; and when the ambient temperature is greater than a preset temperature threshold value, controlling the wiper to stop running.
In the embodiments, the interference of stains (such as ice, snow, dust, soil and other abnormal objects) on the surface of the front windshield on the collected infrared light intensity can be reduced, and the movement speed of the windscreen wiper can be accurately controlled.
In addition, when the ambient temperature is less than or equal to the preset temperature threshold value, the fact that ice and/or snow are/is accumulated on the surface of the front windshield is meant, so that a heating function on the surface of the front windshield can be started, ice/snow is thawed, and then the windscreen wiper is controlled to operate in a first movement speed mode or a fifth movement speed mode. When the ambient temperature is greater than the preset temperature threshold, other substances which cannot be eliminated are arranged on the surface of the front windshield, the windscreen wiper action is stopped, and the need of eliminating the foreign matters through manual treatment is prompted.
In addition, in the embodiment of the present application, in order to further improve the reliability of the comparison, software may be used to filter out the interference signal and calculate an average value of the plurality of infrared light intensities, and compare the average value with a preset threshold value. The preset threshold may also be updated using temperature compensation to eliminate the sensitivity of the device to temperature. The infrared light intensity L1 can be acquired when no rain is present, the infrared light intensity is updated every 3 months to obtain the infrared light intensity L2, the difference value is obtained by comparing the L1 and the L2, and the difference value is uniformly compensated to be within a preset threshold value.
