[0082] Receive command information sent by the control terminal or central control system;

[0083] If it is determined that the code corresponding to the instruction information is a regular code, then the type of the instruction information is determined to be a regular instruction;

[0084] If it is determined that the code corresponding to the instruction information is an enhanced code, then the type of the instruction information is determined to be an enhanced instruction.

[0085] In this example, the control terminal is the control lever or control button of the electronic wiper of the car, and the central control system is the central control display screen connected to the body controller of the vehicle and the computer program running therein.

[0086] Users can generate command information by operating the joystick, control buttons or central control display, which makes it convenient for users to control the electronic wipers.

[0087] In a preferred embodiment, receiving instruction information includes:

[0088] Receive a clarity value sent by the camera; wherein the clarity value represents the clarity of the external environment captured by the camera through the windshield;

[0089] If it is determined that the clarity value exceeds the preset clarity threshold, the type of the instruction information is determined to be a regular instruction;

[0090] If it is determined that the instruction information does not exceed the clarity threshold, the type of the instruction information is determined to be an enhanced instruction.

[0091] In this example, the camera relies on its built-in image processing algorithm and sensor performance to determine whether the view outside the window is blurry and generates a clarity value that reflects the degree of blur.

[0092] Specifically, the camera analyzes the contrast of different parts of the image. If the contrast of the scene outside the window is significantly reduced, such as blurring caused by fog, rain, or dust, the camera may determine that the scene is blurry, and the camera uses the contrast value as the clarity value.

[0093] The camera uses an edge detection algorithm to identify edges in an image. If the edge of the scene outside the window becomes blurred or difficult to identify, the camera may consider the scene to be blurred. The camera uses the blur value generated by the edge detection algorithm to characterize the degree of edge blur as the clarity value.

[0094] The camera evaluates the sharpness of the image, which is the clarity of the details in the image. If the sharpness of the view outside the window decreases, for example due to lens contamination or inaccurate focus, the camera may judge the view as blurry, and the camera will generate a sharpness value for the image and use this sharpness value as the clarity value.

[0096] In this example, the user's current wiping needs are distinguished based on the received command information. If the current user wants to use the electronic wiper normally, or the electronic wiper only needs to operate normally to ensure the cleanliness and transparency of the camera area, the body controller will control the electronic wiper to wipe the windshield using conventional parameters according to conventional instructions.

[0097] In a preferred embodiment, controlling the electronic wiper to wipe the windshield using conventional parameters includes:

[0098] Extracting a conventional wiping speed and a conventional wiping range corresponding to a conventional configuration item of a vehicle body controller; wherein the wiper bar of the electronic wiper includes a target wiper bar; the target wiper bar is a wiper bar capable of wiping a sight area and a camera area on the windshield; the conventional wiping speed includes a target conventional wiping speed, and the conventional wiping range includes a target conventional wiping range;

[0099] The electronic wiper is controlled according to the target conventional wiping speed so that the target wiper rod performs wiping within the target conventional wiping range.

[0100] In this example, if the vehicle needs to be scraped normally, the body controller extracts the normal scraping speed and the normal scraping range to scrape the windshield, wherein the target normal scraping speed and the target normal scraping range can be set according to user needs.

[0101] For example, the target conventional scraping speed in the conventional scraping speed is 60 times / minute; the target conventional scraping range is 0°-100°.

[0102] S305: If the type of instruction information is an enhanced instruction, the electronic wiper is controlled to use enhanced parameters to wipe the camera area of ​​the windshield; wherein the enhanced parameters include enhanced wiping speed and enhanced wiping range; the enhanced wiping speed is used to define the wiping speed of the scraper rod of the electronic wiper, and the enhanced wiping speed is greater than the conventional wiping speed; the enhanced wiping range is used to define the wiping area of ​​the scraper rod of the electronic wiper on the windshield, and the area of ​​the enhanced wiping range is smaller than the area of ​​the conventional wiping range; the camera area is the area on the windshield corresponding to the camera.

[0103] In this example, if the current user wants to perform targeted scraping of the area on the windshield corresponding to the camera to ensure that the area can remain clean and transparent even in heavy rain and when there are large stains on the windshield, the body controller will control the electronic wiper to perform targeted scraping of the area on the windshield corresponding to the camera according to the enhanced instructions to ensure that the camera can clearly capture the external road conditions, thereby ensuring the safety of autonomous driving and reducing the accident rate of autonomous driving.

[0104] In a preferred embodiment, controlling the electronic wiper to wipe the windshield using enhanced parameters includes:

[0105] Extracting an enhanced wiping speed and an enhanced wiping range corresponding to an enhanced configuration item of a vehicle body controller; wherein the wiper bar of the electronic wiper includes a target wiper bar; the target wiper bar is a wiper bar capable of wiping a sight area and a camera area on the windshield; the enhanced wiping speed includes a target enhanced wiping speed, and the enhanced wiping range includes a target enhanced wiping range;

[0106] The electronic wiper is controlled according to the target enhanced wiping speed so that the target wiper rod is wiped within the target enhanced wiping range.

[0107] In this example, if the vehicle needs to perform enhanced scraping on the area corresponding to the camera, the body controller extracts the enhanced scraping speed and enhanced scraping range, and scrapes the area corresponding to the camera, where the target enhanced scraping speed and target enhanced scraping range can be set according to user needs.

[0108] For example, the target enhanced scraping speed is any speed between 80 and 120 times / minute, and the target conventional scraping range is 80° to 90°, wherein the area corresponding to 80° to 90° of the target conventional scraping range is the camera area.
