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

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

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

[0086] The user can generate instruction information by operating the control lever, the control button or the central display screen, which brings convenience to the user for controlling the electronic wiper.

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

[0088] receiving a definition value sent by the camera; wherein the definition value represents the definition degree of the camera shooting the external environment through the windshield;

[0089] If it is determined that the definition value exceeds the preset definition threshold, it is determined that the type of the instruction information is a regular instruction.

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

[0091] In this example, the camera determines whether the scene outside the window is blurred based on its built-in image processing algorithms and sensor performance, and generates a definition value reflecting the degree of blurring.

[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, for example, due to blurring caused by fog, rain or dust, the camera may determine that the scene is blurred, and the camera will use the contrast value as the definition value.

[0093] The camera uses an edge detection algorithm to identify edges in the image. If the edges of the scene outside the window become blurred or difficult to identify, the camera may consider the scene to be blurred, and the camera will generate a blur value representing the degree of edge blurring according to the edge detection algorithm, as the definition value.

[0094] The camera will evaluate the sharpness of the image, i.e. the definition of details in the image. If the sharpness of the scene outside the window decreases, for example, due to lens contamination or inaccurate focal length, the camera may determine that the scene is blurred, and the camera will generate a sharpness value of the image and use the sharpness value as the definition value.

[0096] In this example, the current wiper demand of the user is distinguished according to the received instruction information. If the current user wants to normally use the electronic wiper, or the electronic wiper only needs to normally run to ensure the cleanliness and transparency of the camera area, the vehicle body controller will control the electronic wiper to use the conventional parameters to wipe the windshield according to the conventional instruction.

[0097] In a preferred embodiment, the control of the electronic wiper to use the conventional parameters to wipe the windshield includes:

[0098] extracting the conventional wiping speed and the conventional wiping range corresponding to the conventional configuration item of the vehicle body controller; wherein the wiping rod of the electronic wiper includes a target wiping rod; the target wiping rod is a wiping rod capable of wiping the line-of-sight area and the 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] controlling the electronic wiper according to the target conventional wiping speed to make the target wiping rod wipe within the target conventional wiping range.

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

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

[0102] S305: If the type of the instruction information is an enhanced instruction, control the electronic wiper to use enhanced parameters to wipe the camera area of the windshield; wherein the enhanced parameters include an enhanced wiping speed and an enhanced wiping range; the enhanced wiping speed is used to define the wiping speed of the wiping 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 wiping rod of the electronic wiper on the windshield, and the area of the enhanced wiper range is smaller than the area of the conventional wiper 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 wiping on the area on the windshield corresponding to the camera to ensure that even in heavy rain and the case of heavy stains on the windshield, the area can still be kept clean and transparent, the vehicle body controller will control the electronic wiper to perform targeted wiping on the area on the windshield corresponding to the camera according to the enhanced instruction, to ensure that the camera can clearly capture the external road surface conditions, thereby ensuring the safety of autonomous driving and reducing the accident rate of autonomous driving.

[0104] In a preferred embodiment, the control electronic wiper uses the enhanced parameters to brush the windshield, comprising:

[0105] extracting the enhanced brushing speed and the enhanced brushing range corresponding to the enhanced configuration item of the vehicle body controller; wherein the wiping rod of the electronic wiper comprises a target wiping rod; the target wiping rod is a wiping rod capable of brushing the line-of-sight area and the camera area on the windshield; the enhanced brushing speed comprises a target enhanced brushing speed, and the enhanced brushing range comprises a target enhanced brushing range;

[0106] According to the target enhanced brushing speed, the electronic wiper is controlled to make the target wiping rod brush within the target enhanced brushing range.

[0107] In this example, if the vehicle needs to enhance the brushing of the area corresponding to the camera, the vehicle body controller extracts the enhanced brushing speed and the enhanced brushing range to brush the area corresponding to the camera, wherein the target enhanced brushing speed and the target enhanced brushing range can be set according to user needs.

[0108] For example: the target enhanced brushing speed is any speed in 80-120 times / minute, and the target normal brushing range is 80°-90°. Among them, the area corresponding to 80°-90° of the target normal brushing range is the camera area.
