Description

Technical Field

[0001] Embodiments of the present invention relate to the field of computer processing technology, and in particular to a wiper gear control method, device, electronic device, and storage medium. Background Art

[0002] The wiper is a component installed on a motor vehicle. In rainy and snowy weather, it can effectively remove water stains and dirt accumulated on the front and rear windshields, allowing the driver to see the road conditions in front and behind the vehicle clearly, ensuring people's driving safety in rainy and snowy weather.

[0003] In related technologies, wiper position control often relies on automatic adjustment based on rain sensor sensing. However, in low-temperature environments, if the wiper position is not returned to the off position when the vehicle is powered off, the wipers and windshield may freeze when the vehicle is powered on again, and the washer fluid may also freeze. In this case, the rain sensor may be misled by snowflakes, ice crystals, etc., causing the wipers to automatically activate. Frozen or icing increases resistance, overloading the wiper motor, potentially blowing fuses or damaging the motor, affecting driver visibility and safety.

[0004] In view of this, a wiper gear control method is provided to intelligently adjust the wiper gear, which can intelligently adjust the wiper gear according to real-time conditions, effectively avoid the risk of wiper freezing in low temperature environments, and effectively ensure clear driving vision and driving safety.

[0007] When the target vehicle is powered on, obtaining the forward road information, the external ambient temperature, and the internal ambient temperature of the target vehicle, and determining the first wiper gear state of the target vehicle when the target vehicle was last powered off;

[0011] The wiper gear control module is used to control the wiper gear state of the target vehicle based on the first wiper gear state, the front road information, the external ambient temperature and the vehicle interior ambient temperature, so that the wiper gear of the target vehicle is in the second wiper gear state when it is powered on this time.

[0012] According to another aspect of the present invention, an electronic device is provided, comprising:

[0013] one or more processors;

[0014] a storage device for storing one or more programs,

[0015] When the one or more programs are executed by the one or more processors, the one or more processors implement the wiper gear control method as described in any one of the embodiments of the present invention.

[0016] According to another aspect of the present invention, a computer-readable storage medium is provided, wherein the computer-readable storage medium stores computer instructions, and the computer instructions are used to enable a processor to implement any of the wiper gear control methods of the present invention when executed.

[0017] The technical solution of the embodiment of the present invention determines the first wiper gear state of the target vehicle when it was last powered off by obtaining the road ahead information, external ambient temperature, and interior ambient temperature of the target vehicle when the target vehicle is powered on.

The technical solution of the embodiment of the present invention solves the problem that relying solely on the rain sensor to control the wiper gear is prone to misjudgment in low temperature environments and cannot respond to the risk of wiper freezing in a timely manner, thereby affecting driving safety. It realizes the ability to intelligently adjust the wiper gear according to real-time conditions, effectively avoid the risk of wiper freezing in low temperature environments, and effectively ensure a clear driving field of vision and driving safety.

[0031] Figure 1 This is a flow chart of a wiper gear control method provided by an embodiment of the present invention. This embodiment is applicable to controlling the wiper gear of a vehicle. The method can be executed by a wiper gear control device. The wiper gear control device can be implemented in the form of hardware and / or software. The wiper gear control device can be configured in electronic devices such as computers or servers. Figure 1 As shown, the method of this embodiment includes:

[0032] S110 : When the target vehicle is powered on, obtain the road ahead information, the external ambient temperature, and the internal ambient temperature of the target vehicle, and determine the first wiper gear state of the target vehicle when it was powered off last time.

[0033] The target vehicle can be understood as a vehicle requiring wiper gear control. Optionally, the target vehicle can be a vehicle traveling in rainy or snowy weather conditions. The road ahead information can be understood as information about the road ahead of the target vehicle in its direction of travel. This road ahead information can be used to determine the ice condition of the windshield. In an embodiment of the present invention, obtaining the road ahead information of the target vehicle can include: capturing an image of the road ahead of the target vehicle using an image capture device installed at a preset position on the target vehicle, and determining the road ahead information of the target vehicle based on the image. In an embodiment of the present invention, determining the road ahead information of the target vehicle based on the image ahead specifically includes: extracting information from the image ahead, and then determining the road ahead information of the target vehicle based on the extracted information. Optionally, the image capture device can be an onboard camera. The preset position can be determined based on the field of view of the vehicle's windshield. The number of preset positions can be one, two, or more. The road ahead image can be understood as an image captured by the image capture device installed at the preset position on the target vehicle. The number of road ahead images can be one, two, or more. When there are multiple images of the road ahead at the same moment, the multiple images of the road ahead at the same moment can be subjected to preset image processing from at least one dimension of image enhancement, feature extraction and fusion, target detection and recognition, scene understanding and semantic segmentation.

[0034] In an embodiment of the present invention, the external ambient temperature can be understood as the temperature of the surrounding environment outside the vehicle. In an embodiment of the present invention, the external ambient temperature can be obtained by a temperature sensor outside the vehicle. In an embodiment of the present invention, the temperature sensor outside the vehicle can be installed at the front of the vehicle to accurately measure the temperature of the surrounding environment of the vehicle. The in-vehicle ambient temperature can be understood as the ambient temperature inside the target vehicle. In an embodiment of the present invention, the in-vehicle ambient temperature can be obtained by a temperature sensor inside the vehicle. In an embodiment of the present invention, the in-vehicle temperature sensor can be installed near the dashboard of the vehicle or at the air-conditioning outlet.

[0035] In an embodiment of the present invention, the first wiper gear state can be understood as the wiper gear state of the target vehicle when it was powered off last time, when the target vehicle is powered on this time. In actual applications, the states corresponding to the wiper gears may include a wiper-off state and a wiper-on state. The wiper-on state may be a high-speed gear state, a low-speed gear state, and an automatic gear state. It can be understood that when the wiper gear state is in a high-speed gear state or a low-speed gear state, the wiper starts and performs a high-speed or low-speed wiping action; when the wiper gear state is in an automatic gear state, the wiper can be controlled to perform a wiping action according to the current state requirements sensed by the rain sensor. The movement state of the wiper can be divided into a high-speed drive output and a low-speed drive output. In an embodiment of the present invention, the first wiper gear state can be a wiper-on state or a wiper-off state.

[0036] In an embodiment of the present invention, before obtaining the road ahead information, external ambient temperature, and interior ambient temperature of the target vehicle and determining the first wiper gear state of the target vehicle when the power was last turned off, the method further includes: determining whether a gear control operation for the wiper gear state of the target vehicle is received; if not, then performing the operation of obtaining the road ahead information, external ambient temperature, and interior ambient temperature of the target vehicle and determining the first wiper gear state of the target vehicle when the power was last turned off. The gear control operation can be understood as the control operation of the wiper gear of the target vehicle by the vehicle driver. This processing can enhance the intelligence and personalization of the system and intelligently adapt to different scenarios. The driver can manually adjust the wiper gear in a specific scenario based on his or her own experience or special needs.

[0037] In an embodiment of the present invention, when the driver has operated the wiper gear according to his or her own judgment and needs, the system will no longer automatically obtain relevant information and determine the gear status when the power was last turned off, thereby avoiding unnecessary system intervention and enabling the driver to control the wiper according to his or her own driving habits, thereby improving the autonomy and comfort of the driving experience.

[0038] S120. Based on the first wiper gear state, the front road information, the external ambient temperature, and the vehicle interior ambient temperature, control the wiper gear state of the target vehicle so that the wiper gear of the target vehicle is in the second wiper gear state when it is powered on this time.

[0039] The second wiper gear state can be understood as the wiper gear state of the target vehicle at the current power-on. The second wiper gear state can be the maintained first wiper gear state; or it can be the wiper gear state obtained by adjusting the first wiper gear state. In short, the first wiper gear state and the second wiper gear state can be the same or different.

[0040] Specifically, a comprehensive analysis can be performed on the first wiper gear state, the road ahead information, the external ambient temperature, and the vehicle interior ambient temperature based on the first wiper gear state, the road ahead information, the external ambient temperature, and the vehicle interior ambient temperature. Furthermore, based on the analysis result, if the analysis result is the first result, the wiper gear state of the target vehicle can be maintained, and the first wiper gear state of the target vehicle at the last power-off can be used as the second wiper gear state for the target vehicle at the current power-on. If the analysis result is the second result, the wiper gear state of the target vehicle can be switched from the first wiper gear state to the second wiper gear state, i.e., the wiper gear state of the target vehicle at the current power-on can be the second wiper gear state.

[0041] The technical solution of the embodiment of the present invention determines the first wiper gear state of the target vehicle when it was last powered off by obtaining the road ahead information, external ambient temperature, and interior ambient temperature of the target vehicle when the target vehicle is powered on. This solution fully considers the multi-dimensional factors that affect wiper control, including ambient temperature conditions, road conditions, and the initial wiper gear state. Based on the first wiper gear state, the road ahead information, the external ambient temperature, and the interior ambient temperature, the wiper gear state of the target vehicle is controlled so that the wiper gear of the target vehicle is in the second wiper gear state when it is powered on this time. The technical solution of the embodiment of the present invention solves the problem that relying solely on the rain sensor to control the wiper gear is prone to misjudgment in low temperature environments and cannot respond to the risk of wiper freezing in a timely manner, thereby affecting driving safety. It realizes the ability to intelligently adjust the wiper gear according to real-time conditions, effectively avoid the risk of wiper freezing in low temperature environments, and effectively ensure a clear driving field of vision and driving safety.

[0042] Figure 2 A flow chart of a wiper gear control method provided in an embodiment of the present invention, based on the aforementioned embodiment, optionally, the wiper gear state of the target vehicle is controlled based on the first wiper gear state, the road ahead information, the external ambient temperature and the vehicle interior ambient temperature, so that the target vehicle is in the second wiper gear state when the wiper gear is powered on this time, including: determining the temperature difference based on the external ambient temperature and the vehicle interior ambient temperature, and determining the road clarity based on the road ahead information; controlling the wiper gear state of the target vehicle based on the external ambient temperature, the temperature difference, the first wiper gear state and the road clarity, so that the target vehicle is in the second wiper gear state when the wiper gear is powered on this time. Among them, the technical features that are the same or similar to those in the aforementioned embodiment will not be repeated here. Figure 2 As shown, the method of this embodiment specifically includes:

[0043] S210: When the target vehicle is powered on, obtain the road ahead information, the external ambient temperature, and the internal ambient temperature of the target vehicle, and determine the first wiper gear state of the target vehicle when it was powered off last time.

[0044] S220 : Determine a temperature difference based on the external ambient temperature and the vehicle interior ambient temperature, and determine road clarity based on the front road information.

[0045] In this embodiment of the present invention, the road clarity is determined based on the road ahead information, specifically by determining image extraction information extracted from the road ahead image, and determining the road clarity based on the image extraction information.

[0046] In an embodiment of the present invention, determining the temperature difference based on the external ambient temperature and the vehicle interior ambient temperature includes: performing a difference calculation on the external ambient temperature and the vehicle interior ambient temperature to obtain a difference calculation result, namely, the temperature difference.

[0047] S230: Based on the external ambient temperature, the temperature difference, the first wiper gear state, and the road clarity, control the wiper gear state of the target vehicle so that the wiper gear of the target vehicle is in a second wiper gear state when it is powered on this time.

[0048] In an embodiment of the present invention, there are multiple ways to control the wiper gear state of the target vehicle based on the external ambient temperature, the temperature difference, the first wiper gear state and the road clarity so that the wiper gear of the target vehicle is in the second wiper gear state when it is powered on this time.

[0049] As an optional implementation in an embodiment of the present invention, the controlling of the wiper gear state of the target vehicle based on the external ambient temperature, the temperature difference, the first wiper gear state and the road clarity may include: when the first wiper gear state is the wiper-on state, if the road clarity is lower than a first clarity threshold, the external ambient temperature is lower than a first temperature threshold and the temperature difference is lower than a first temperature difference threshold, then adjusting the wiper gear state of the target vehicle to the wiper-off state.

[0050] It should be noted that in this embodiment of the present invention, the clarity threshold can be understood as a preset standard value used to measure the clarity of the image of the road ahead. It is understood that when the road clarity value calculated using image processing technology is lower than the threshold, it can be determined that the current visual conditions of the windshield or the road ahead are poor, potentially affecting driving safety, such as the possibility that the wipers may be frozen on the windshield. When the clarity value is higher than or equal to the threshold, it can be determined that the road image clarity is within an acceptable range. The temperature threshold can be understood as a preset temperature value used to determine whether the external ambient temperature is within a range that may affect the effectiveness of the wipers. That is, when the first wiper gear is in the on state, if the external ambient temperature is lower than the temperature threshold, it can be determined that the current environment may contain factors that are unfavorable to wiper operation. The temperature difference threshold can be understood as a preset standard value used to measure the degree of difference between the internal ambient temperature of the target vehicle and the external ambient temperature. Specifically, when the temperature difference between inside and outside the vehicle is lower than the threshold, it can be determined that the temperature difference between inside and outside the target vehicle is small, and there may be no obvious fog or frost on the windshield; when the temperature difference is higher than the threshold, the windshield may fog or frost, affecting the driving vision.

[0051] Specifically, when the first wiper gear state is the wiper-on state, if the road clarity is lower than a first clarity threshold, the external ambient temperature is lower than a first temperature threshold, and the temperature difference is lower than a first temperature difference threshold, the wiper gear state of the target vehicle can be adjusted to the wiper-off state. In this embodiment of the present invention, the first clarity threshold can be set according to actual needs and is not specifically limited here. The first temperature threshold can be set according to actual needs and is not specifically limited here. The first temperature difference threshold can be set according to actual needs and is not specifically limited here.

[0052] As another optional implementation in the embodiment of the present invention, the controlling of the wiper gear state of the target vehicle based on the external ambient temperature, the temperature difference, the first wiper gear state and the road clarity may include: when the first wiper gear state is the wiper off state, if the road clarity is lower than a second clarity threshold, the external ambient temperature is lower than a second temperature threshold and the temperature difference is lower than a second temperature difference threshold, controlling the wiper gear state of the target vehicle to remain in the wiper off state.

[0053] Specifically, when the first wiper gear state is the wiper-off state, if the road clarity is lower than a second clarity threshold, the external ambient temperature is lower than a second temperature threshold, and the temperature difference is lower than a second temperature difference threshold, the wiper gear state of the target vehicle can be controlled to remain in the wiper-off state. In this embodiment of the present invention, the second clarity threshold can be set according to actual needs and is not specifically limited here. The second temperature threshold can be set according to actual needs and is not specifically limited here. The second temperature difference threshold can be set according to actual needs and is not specifically limited here.

[0054] As another optional implementation in the embodiment of the present invention, the controlling of the wiper gear state of the target vehicle based on the external ambient temperature, the temperature difference, the first wiper gear state and the road clarity may include: when the first wiper gear state is the wiper-on state and the road clarity is lower than a third clarity threshold, if the external ambient temperature is not lower than the third temperature threshold or the temperature difference is not lower than the third temperature difference threshold, then maintaining the wiper gear state of the target vehicle at the wiper-on state.

[0055] Specifically, when the first wiper gear state is the wiper-on state and the road clarity is lower than a third clarity threshold, if the external ambient temperature is not lower than the third temperature threshold or the temperature difference is not lower than the third temperature difference threshold, the wiper gear state of the target vehicle can be maintained in the wiper-on state. In this embodiment of the present invention, the third clarity threshold can be set according to actual needs and is not specifically defined herein. The third temperature threshold can be set according to actual needs and is not specifically defined herein. The third temperature difference threshold can be set according to actual needs and is not specifically defined herein.

[0056] It should also be noted that, in an embodiment of the present invention, at least two of the first clarity threshold, the second clarity threshold, and the third clarity threshold may be the same, or may all be different. Specifically, the first clarity threshold, the second clarity threshold, and the third clarity threshold may all be the same, or may be partially the same, or may be completely different. At least two of the first temperature threshold, the second temperature threshold, and the third temperature threshold may be the same, or may all be different. Specifically, the first temperature threshold, the second temperature threshold, and the third temperature threshold may all be the same, or may be partially the same, or may be completely different. At least two of the first temperature difference threshold, the second temperature difference threshold, and the third temperature difference threshold may be the same, or may all be different. Specifically, the first temperature difference threshold, the second temperature difference threshold, and the third temperature difference threshold may all be the same, or may be partially the same, or may be completely different.

[0057] The technical solution of the embodiment of the present invention is to determine the temperature difference based on the external ambient temperature and the internal ambient temperature, and determine the road clarity based on the road ahead information; based on the external ambient temperature, the temperature difference, the first wiper gear state and the road clarity, the wiper gear state of the target vehicle is controlled so that the wiper gear of the target vehicle is in the second wiper gear state when it is powered on this time, thereby realizing intelligent control of the wiper gear state of the target vehicle.

[0059] The information acquisition module 310 is configured to acquire, when the target vehicle is powered on, information about the road ahead of the target vehicle, the external ambient temperature, and the internal ambient temperature of the target vehicle, and determine the first wiper gear state of the target vehicle when the target vehicle was last powered off;

[0060] The wiper gear control module 320 is used to control the wiper gear state of the target vehicle based on the first wiper gear state, the front road information, the external ambient temperature and the interior ambient temperature, so that the wiper gear of the target vehicle is in the second wiper gear state when it is powered on this time.

[0061] The technical solution of the embodiment of the present invention uses an information acquisition module 310 to obtain the target vehicle's forward road information, external ambient temperature, and interior ambient temperature when the target vehicle is powered on, and determines the target vehicle's first wiper gear state when it was last powered off.

[0066] Optionally, the wiper gear control device further includes a control mode determination module. The control mode determination module is configured to determine whether a gear control operation for the wiper gear state of the target vehicle has been received before obtaining the target vehicle's forward road information, the external ambient temperature, and the vehicle interior ambient temperature and determining the target vehicle's first wiper gear state when the power was last turned off; if not, then perform the operation of obtaining the target vehicle's forward road information, the external ambient temperature, and the vehicle interior ambient temperature and determining the target vehicle's first wiper gear state when the power was last turned off.

[0067] The information acquisition module 310 is used to determine whether a gear control operation for the wiper gear state of the target vehicle is received; if not, obtain the front road information, external ambient temperature and interior ambient temperature of the target vehicle to determine the first wiper gear state of the target vehicle when it was last powered off.

[0068] Optionally, the information acquisition module 310 includes a road information acquisition unit, wherein the road information acquisition unit is configured to capture an image of the road ahead of the target vehicle using an image acquisition device installed at a preset position of the target vehicle, and determine the road ahead information of the target vehicle based on the image.
