Description

Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to a control method for a vehicle wiper, an electronic device and a vehicle. Background Art

[0002] At present, many vehicles are equipped with windshield wiper thermal protection function, which is an important automobile safety function, mainly to prevent the wiper from being damaged due to excessive work in high temperature environment. The windshield wiper thermal protection device usually monitors the temperature of the wiper motor through a temperature sensor. Once the temperature exceeds the set safety threshold, the thermal protection will be activated to suspend the wiper operation.

[0003] There are many reasons for triggering the wiper thermal protection function, one of which is continuous instantaneous starting current. Continuous instantaneous starting current will cause the wiper motor to overheat, and then the wiper thermal protection function will suspend the wiper operation when the motor is detected to be overheated, resulting in the normal wiper function being affected, thus affecting the user's driving vision and causing driving risks for the user. Summary of the invention

[0004] In view of this, the purpose of the present application is to propose a control method for a vehicle wiper, an electronic device and a vehicle, which solves the problem of continuous instantaneous starting current triggering the wiper thermal protection function in the prior art.

[0005] Based on the above purpose, the present application provides a method for controlling a vehicle wiper, comprising:

[0006] In response to detecting that a preset number of single wiping requests received within a preset time period has been reached, determining an intermittent wiping parameter of the wiper;

[0007] The wiper is controlled to perform intermittent wiping based on the intermittent wiping parameter.

[0008] In some optional implementations, the intermittent wiping parameter includes a wiping intermittent time, and determining the intermittent wiping parameter of the wiper includes:

[0009] Acquiring water droplet detection information on the windshield of the vehicle and the motor temperature of the wiper;

[0010] Based on the water drop detection information and the motor temperature, a wiping interval time of the wiper is determined.

[0013] An average interval time is determined based on all the interval times, and a wiping pause time of the wiper is determined based on the total time and the average interval time.

[0014] In some optional implementations, the intermittent wiping parameter further includes the number of wiping executions or the wiping execution duration. Determining the intermittent wiping parameter of the wiper includes:

[0015] Obtaining a preset number of executions or a preset execution duration corresponding to the preset time;

[0016] Determine the water drop variation trend based on the water drop detection amount at each moment in the water drop detection information, adjust the preset execution times or the preset execution duration based on the water drop variation trend, and obtain the scraping execution times or the scraping execution duration; or

[0017] The preset execution times or the preset execution duration are adjusted based on the motor temperature to obtain the scraping and wiping execution times or the scraping and wiping execution duration.

[0018] In some optional embodiments, the method further comprises:

[0019] During the intermittent wiping process of the wiper, in response to detecting that the vehicle meets a preset wiper parameter update condition, updating the wiping intermittent time and recording the remaining execution times or remaining execution duration of the wiper;

[0020] The wiper is controlled to perform intermittent wiping according to the updated wiping intermittent time until the remaining execution times or the remaining execution duration is reached.

[0021] In some optional implementations, in response to detecting that the vehicle meets a preset wiper parameter update condition, the method includes:

[0022] In response to receiving a new single wipe request, determining that the vehicle meets the preset wiper parameter update condition;

[0023] Accordingly, updating the scraping interval time includes:

[0024] The difference between the time when a new single wiping request is received and the time when intermittent wiping is started is determined, and the wiping intermittent time is updated based on the difference.

[0025] In some optional implementations, in response to detecting that the vehicle meets a preset wiper parameter update condition, the method includes:

[0026] In response to detecting that the vehicle is accelerating and the speed increase rate of the vehicle is greater than a preset increase rate, determining that the vehicle meets the preset wiper parameter update condition;

[0027] Accordingly, updating the scraping interval time includes:

[0028] The speed difference between the vehicle before and after the acceleration is determined, and the wiping interval time is updated based on the speed difference.

This method can control the wiper to perform intermittent wiping when the wiper needs to perform single wiping multiple times, thereby avoiding continuous instantaneous starting current caused by multiple executions of single wiping in a short period of time, thereby avoiding the wiper thermal protection function from being triggered and affecting the use of the wiper, ensuring that the user's driving field of view is not restricted, and improving the user's driving safety.

[0044] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0045] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0046] Before introducing in detail the control method of the vehicle wiper provided in the embodiment of the present application, the technical problem solved by the method is first described.

[0047] In the prior art, there are two main reasons for the thermal protection of windshield wipers. One is continuous dry wiping, which can be avoided by rain detection; the other is continuous instantaneous starting current, both of which damage the wiper motor. At the same time, it will also cause the thermal protection function of the windshield wiper to be activated, affecting the normal wiper function, and even worse, affecting the driving safety of users.

[0048] Therefore, for the second situation mentioned above, an embodiment of the present application provides a method for controlling a vehicle wiper, which can control the wiper to perform intermittent wiping when multiple single wiping requests are detected within a certain period of time, thereby avoiding the activation of the wiper thermal protection function due to multiple single wiping requests in a short period of time.

[0049] Figure 1 A flow chart of a method for controlling a vehicle wiper is provided in an embodiment of the present application. The method can be executed by a control device for the vehicle wiper, and the device can be integrated into an electronic device such as an ECU (Electronic Control Unit) of the vehicle by means of hardware and / or software.

[0050] See also Figure 1 The vehicle wiper control method provided in the embodiment of the present application comprises the following steps:

[0051] S110: In response to detecting that the number of single wiping requests received within a preset time reaches a preset number, determining an intermittent wiping parameter of the wiper.

[0052] The single wiping request can be used to request the wiper to perform one wiping operation, that is, the wiper swipes the windshield once. It should be noted that each time the wiper motor responds to a single wiping request, an instantaneous starting current is generated.

[0053] In the embodiment of the present application, the preset time and the preset number can be a preset time capable of triggering the windshield wiper thermal protection function and a corresponding single wipe execution number. For example, the preset time can be 8 seconds, and the preset number can be 3 times.

[0054] Specifically, the ECU can receive a single wiping request sent by the RLS (Rain Light Sensor) in the vehicle, and before responding to the single wiping request, determine whether the number of single wiping requests received within a preset time has reached a preset number. If not, it can continue to respond to the single wiping request and control the wiper to perform a single wiping.

[0055] If it is determined that the number of single wiping requests received within the preset time has reached a preset number, it can be determined that the vehicle is in an environment with light and continuous rainfall, and single wiping requests may continue to be received subsequently. However, since the single wiping requests received previously have all been responded to, if single wiping is continued subsequently, it may cause the motor to overheat and trigger the wiper thermal protection function. Therefore, it is possible to refuse to continue to respond to single wiping requests, thereby controlling the wiper to perform intermittent wiping.

[0056] It should be noted that intermittent wiping refers to the wiper continuously performing intermittent wiping, which is different from multiple single wiping. Single wiping is completed after the wiper completes one wiping, while multiple single wiping requires multiple requests for wiping, resulting in the wiper motor generating instantaneous starting current multiple times. However, the whole process of intermittent wiping is: wait for a certain intermittent time after completing one wiping, and then continue to perform one wiping, repeating this process until the wiping reaches the set time or the set number of times. During this process, the wiper motor will not generate instantaneous starting current multiple times.

[0057] Specifically, the intermittent wiping parameters of the wiper can be determined first, so as to perform intermittent wiping according to the intermittent wiping parameters. The intermittent wiping parameters can include the wiping intermittent time, which can be the interval between each wiping. The intermittent wiping parameters can also include the number of wiping executions or the wiping execution duration, where the number of wiping executions is the number of times the wiper performs intermittent wiping, and the wiping execution duration is the total duration of the intermittent wiping of the wiper.

[0058] For example, when it is detected that the number of single wiping requests received within a preset time reaches a preset number, a flag bit can be cached, and then the wiper can be controlled to perform intermittent wiping based on the flag bit. The ECU can determine the wiping interval time according to the sensitivity of the wiper, and the wiping execution time can use the default value, such as 20s.

[0059] In a specific implementation, the intermittent wiping parameter includes the wiping intermittent time, and determining the intermittent wiping parameter of the wiper includes the following steps:

[0060] Step 11, obtaining water droplet detection information on the windshield of the vehicle and the motor temperature of the wiper;

[0061] Step 12: Determine the wiper wiping interval time based on the water drop detection information and the motor temperature.

[0062] The water droplet detection information may include the amount of water droplet detection at each moment and the distribution of water droplets at each moment. Specifically, in step 11, the water droplets on the windshield may be detected based on a rain sensor mounted on the vehicle to obtain water droplet detection information; and the temperature of the wiper motor may be collected based on a temperature sensor to obtain the motor temperature.

[0063] Furthermore, in step 12, the wiper wiping interval can be determined based on the water droplet detection information and the motor temperature, with the goal of maintaining the user's driving vision as much as possible and the motor temperature not exceeding the high temperature threshold.

[0064] For example, the difference in water droplet amount between adjacent moments can be determined by the water droplet amount detected at each moment in the water droplet detection information, and then based on the difference in water droplet amount, the corresponding scraping interval time can be queried in the pre-constructed water droplet time mapping relationship, for example, the smaller the difference in water droplet amount, the greater the scraping interval time. The water droplet time mapping relationship can describe the corresponding relationship between each water droplet amount and each scraping interval time.

[0065] Furthermore, the queried wiper intermittent time can be adjusted based on the motor temperature. For example, it can be directly determined whether the motor temperature is greater than a preset temperature threshold. If so, the wiper intermittent time is reduced. Alternatively, based on the queried wiper intermittent time and the motor temperature, the temperature of the motor after the wiper performs intermittent wipes at the wiper intermittent time is predicted to obtain a predicted motor temperature. If the predicted motor temperature is greater than a high temperature threshold, the wiper intermittent time can be reduced.

[0066] Through the above implementation, it is possible to determine the wiping intermittent time based on the water droplet detection information and the motor temperature. While ensuring that the intermittent wiping does not trigger the wiper thermal protection function, it is possible to quickly clear the accumulated water on the windshield through intermittent wiping to ensure that the user's driving vision is not restricted.

[0067] In addition to determining the wiping interval by using the water droplet detection information and the motor temperature, in the embodiment of the present application, the amount of water on the windshield can also be estimated based on the time when each single wiping request is received, thereby determining the wiping interval.

[0068] In another specific implementation, the intermittent wiping parameter includes a wiping intermittent time, and determining the intermittent wiping parameter of the wiper includes the following steps:

[0069] Step 21, determining the total time of receiving a preset number of single scraping requests and the interval time between receiving each single scraping request;

[0070] Step 22: determine an average interval time based on all interval times, and determine a wiper wiping interval time based on the total time and the average interval time.

[0071] In step 21, the total time of receiving a preset number of single scraping requests can be determined according to the reception time of the first single scraping request and the reception time of the last single scraping request within the preset time. In addition, the interval time between receiving any two adjacent single scraping requests can be calculated.

[0072] Furthermore, in step 22, all the interval times may be averaged to obtain an average interval time, and then the wiper interval time of the wiper may be determined by the average interval time and the total time. For example, the shorter the average interval time and the total time, the shorter the interval at which the RLS detects that a wipe is required, that is, the faster the rate at which the water droplets fall, and then the shorter the wiper interval time may be determined.

[0073] Exemplarily, different total times and scraping interval times corresponding to average interval times may be preset and stored in association, and then the corresponding scraping interval time may be queried based on the total time and the average interval time.

[0074] In the above embodiment, taking into account the characteristic that the time for receiving a single wiping request can reflect the amount of water on the windshield, the intermittent wiping time for performing intermittent wiping is determined by receiving the total time of a preset number of single wiping requests and the interval time between receiving each single wiping request. This allows the intermittent wiping to meet the need for clearing accumulated water as much as possible, thereby ensuring that the user's driving field of vision is not limited by water on the windshield.

[0075] In addition to determining the intermittent wiping time, considering that when a single wiping request is received multiple times, the rainfall is usually small, and in this case, there is no need to continuously perform intermittent wiping to further avoid excessive motor temperature. Therefore, the number of wiping executions or the duration of wiping execution of the wiper intermittent wiping can also be determined, and the time of intermittent wiping can be controlled by the number of wiping executions or the duration of wiping execution.

[0076] Exemplarily, the number of scraping executions or the length of scraping execution time corresponding to the number of single scraping requests may be preset, and then the number of scraping executions or the length of scraping execution time may be queried based on the preset number.

[0077] In some embodiments, the intermittent wiping parameter further includes the number of wiping executions or the wiping execution duration. Determining the intermittent wiping parameter of the wiper includes the following steps:

[0078] Step 31, obtaining a preset number of executions or a preset execution duration corresponding to a preset time;

[0079] Step 32: determine the water drop change trend based on the water drop detection amount at each moment in the water drop detection information, adjust the preset execution times or the preset execution duration based on the water drop change trend to obtain the scraping execution times or the scraping execution duration; or, adjust the preset execution times or the preset execution duration based on the motor temperature to obtain the scraping execution times or the scraping execution duration.

[0080] In step 31, a preset number of executions or a preset execution duration corresponding to each time may be preset, and then the corresponding preset number of executions or preset execution duration may be queried through the preset time. For example, the longer the preset time, the more preset number of executions and the longer the preset execution duration.

[0081] Furthermore, in step 32, the amount of water droplets detected at each moment in the water droplet detection information can be used to calculate the amount of water droplets changed at each moment, thereby obtaining a water droplet change trend. If it is determined based on the water droplet change trend that the amount of water droplets presents a stable trend or an increasing trend with the increase of time, it means that water droplets are continuously detected on the windshield or the amount of water droplets gradually increases, and therefore, the preset execution time can be extended to obtain the scraping and wiping execution time, or the preset execution times can be increased to obtain the scraping and wiping execution times.

[0082] If it is determined based on the change trend of water droplets that the amount of water droplets shows a decreasing trend with the increase of time, it means that the water droplets on the windshield are gradually decreasing. Therefore, the preset execution time can be reduced to obtain the scraping execution time, or the preset execution times can be reduced to obtain the scraping execution times.

[0083] In addition to adjusting the preset number of executions or the preset execution duration based on the water droplet change trend, the adjustment can also be made based on the motor temperature. For example, it can be determined whether the motor temperature is greater than a preset temperature threshold, or the temperature of the wiper after intermittent wiping with a preset number of executions or a preset execution duration can be predicted based on the motor temperature to obtain a predicted motor temperature, and it can be determined whether the predicted motor temperature is greater than a high temperature threshold.

[0084] If the motor temperature is greater than the preset temperature threshold, or the predicted motor temperature is greater than the high temperature threshold, the preset execution time can be reduced to obtain the scraping execution time, or the preset execution times can be reduced to obtain the scraping execution times to avoid overheating of the wiper motor.

[0085] Through the above implementation, the preset number of executions or the preset execution duration can be first determined by the preset time, and then adjusted by the water droplet detection amount or the motor temperature to obtain the scraping execution number or the scraping execution duration, so that intermittent scraping can meet the water removal needs as much as possible, ensuring that the user's driving vision is not limited by water accumulation on the windshield, and can also avoid the wiper motor temperature being too high, thereby avoiding the wiper thermal protection function from being triggered and causing the wiper to fail to work.

[0086] S120: Controlling the wiper to perform intermittent wiping based on the intermittent wiping parameters.

[0087] Among them, the intermittent wiping parameters may include the wiping intermittent time and the wiping execution time. Controlling the wiper to perform intermittent wiping based on the intermittent wiping parameters may be: controlling the wiper to perform intermittent wiping with the wiping intermittent time until the intermittent wiping time reaches the wiping execution time.

[0088] Alternatively, the intermittent wiping parameters may include the wiping intermittent time and the number of wiping executions. Controlling the wiper to perform intermittent wiping based on the intermittent wiping parameters may be: controlling the wiper to perform intermittent wiping with the wiping intermittent time until the number of intermittent wiping reaches the number of wiping executions.

[0089] Taking into account that the demand for clearing water on the windshield may change during the intermittent scraping process, in an embodiment of the present application, the intermittent scraping parameters can also be updated in real time to ensure that the intermittent scraping can meet the demand in a timely manner.

[0090] In a specific implementation, the method provided in the embodiment of the present application further includes the following steps:

[0091] Step 41: During the intermittent wiping process of the wiper, in response to detecting that the vehicle meets a preset wiper parameter update condition, updating the wiping intermittent time and recording the remaining number of executions or the remaining execution time of the wiper;

[0092] Step 42: Control the wiper to perform intermittent wiping according to the updated wiping intermittent time until the remaining execution times or the remaining execution time is reached.

[0093] The preset wiper parameter update condition may be a condition in which the demand for clearing water from the windshield changes, such as receiving a new single wipe request or the vehicle speeding up.

[0094] Specifically, in step 41, during the intermittent wiping process, it can be detected whether the vehicle meets the preset wiper parameter update conditions. If it is detected that it is satisfied, the wiping interval time can be updated and the remaining number of executions or the remaining execution time of the intermittent wiping can be recorded.

[0095] Furthermore, in step 42, the wiper can be controlled to perform intermittent wiping according to the updated wiping intermittent time until the remaining execution times or the remaining execution time is reached, that is, the intermittent wiping is completed.

[0096] By updating the wiping interval time according to whether the wiper parameter update conditions are met during the intermittent wiping process, it can be ensured that the intermittent wiping better meets the needs of clearing accumulated water, further improve the clarity of the user's driving field of view, and ensure the user's driving safety.

[0097] In one example, in response to detecting that the vehicle meets a preset wiper parameter update condition, the method includes: in response to receiving a new single wipe request, determining that the vehicle meets the preset wiper parameter update condition;

[0098] Accordingly, updating the scraping intermittent time includes: determining the difference between the time of receiving a new single scraping request and the time of starting the intermittent scraping, and updating the scraping intermittent time based on the difference.

[0099] Among them, the wiper parameter update condition may be the receipt of a new single wiping request, that is, during the intermittent wiping process, if a new single wiping request is detected, it means that the intermittent wiping at this time may not be able to meet the demand, and RLS detects the need to additionally trigger a single wiping, so the wiping interval time can be reduced at this time.

[0100] Specifically, the difference between the time of receiving a new single scraping request and the time of starting intermittent scraping can be calculated. The difference can reflect how long the intermittent scraping fails to meet the demand, and the scraping interval time can be reduced based on the difference.

[0101] Exemplarily, the adjustment amount can be determined based on the difference, and the scraping interval time is subtracted from the adjustment amount to obtain the updated scraping interval time; for example, the smaller the difference, the more it means that the water removal demand cannot be met soon after intermittent scraping is performed, and a larger adjustment amount can be determined at this time.

[0102] Through the above example, it is possible to adjust the scraping interval time in response to receiving a new single scraping request during the intermittent scraping process, thereby ensuring that the intermittent scraping meets the need to clear water on the glass in a timely manner and improving the user's driving experience. At the same time, the difference between the time when the new single scraping request is received and the time when the intermittent scraping is started can be used to reflect the demand for water removal, and the scraping interval time can be adjusted based on this, which can make the adjustment more precise.

[0103] In another example, in response to detecting that the vehicle satisfies a preset wiper parameter update condition, the method includes: in response to detecting that the vehicle speeds up and the speed increase rate of the vehicle is greater than a preset increase rate, determining that the vehicle satisfies the preset wiper parameter update condition;

[0104] Accordingly, updating the scraping and wiping interval time includes: determining the speed difference between the vehicle before and after the acceleration, and updating the scraping and wiping interval time based on the speed difference.

[0105] The wiper parameter update condition may be that the vehicle speed is detected to be increased and the speed increase rate of the vehicle is greater than a preset increase rate. The speed increase rate may be the ratio of the speed difference before and after the speed increase to the vehicle speed before the extraction. That is, during the intermittent wiping process, if the vehicle speed is detected to be increased and the speed increase rate of the vehicle is greater than a preset increase rate, it means that the speed increase may cause more water to accumulate on the windshield, and the intermittent wiping may not meet the demand. Therefore, the wiping interval time may be reduced at this time.

[0106] Specifically, the speed difference between before and after the speed increase can be calculated, and the speed difference can reflect the amount of water accumulation on the windshield, that is, the greater the speed difference, the more water accumulation on the windshield, and the adjustment amount can be determined by the speed difference, and the wipe interval time is subtracted from the adjustment amount to obtain the updated wipe interval time. For example, the greater the speed difference, the more water accumulation on the windshield, the more it is necessary to wipe with a shorter wipe interval time, and the more adjustment amount is determined.

[0107] Through the above example, during the intermittent scraping process, in response to detecting a high acceleration of the vehicle, the scraping interval time can be adjusted, which can ensure that the intermittent scraping meets the demand for clearing water on the glass in time and improve the user's driving experience. At the same time, the speed difference can also reflect the demand for clearing water, and the scraping interval time can be adjusted based on this, which can make the adjustment more precise.

[0108] It should be noted that during the intermittent wiping process, if other wiping requests other than a single wiping request are detected by the RLS, such as continuous low-speed requests or continuous high-speed requests sent by the RLS when the rain increases, the intermittent wiping can be suspended and other wiping requests can be executed to ensure that the user's driving field of vision is not restricted.

[0109] In some embodiments, the method provided in the embodiments of the present application further includes the following steps:

[0110] Step 51, in the process of intermittent wiping by the wiper, in response to receiving other wiping requests except the single wiping request, controlling the wiper to suspend the intermittent wiping, and recording the remaining execution times or remaining execution time of the wiper;

[0111] Step 52: Control the wiper to perform wiping operations corresponding to other wiping requests, and in response to receiving a new single wiping request, control the wiper to stop the wiping operation, and control the wiper to resume intermittent wiping based on the remaining number of executions or the remaining execution duration.

[0112] Among them, other scraping requests other than the single scraping request may be continuous low-speed requests or continuous high-speed requests sent by RLS, etc. Specifically, if other scraping requests other than the single scraping request are detected, the intermittent scraping may be paused, and the remaining execution times or remaining execution time of the intermittent scraping may be recorded.

[0113] Furthermore, it is possible to respond to other wiping requests and control the wiper to perform wiping operations corresponding to other wiping requests, such as continuous low-speed wiping, continuous high-speed wiping, etc., to ensure the efficiency of clearing accumulated water.

[0114] During the process of executing the wiping operations corresponding to other wiping requests, if a new single wiping request sent by RLS is detected, it means that RLS has detected a decrease in rain. It can control the wiper to stop executing the wiping operations corresponding to other wiping requests, and continue to execute intermittent wiping, and continue to execute according to the remaining number of executions or the remaining execution time recorded previously.

[0115] Through the above-mentioned implementation mode, in the process of executing intermittent wiping, other wiping requests after the increase in rainfall can be responded to in time to ensure the efficiency of clearing water from the glass. In the process of responding to other wiping requests, for a single wiping request after the rainfall decreases, intermittent wiping can be restored according to the remaining number of executions or the remaining execution time to avoid overheating of the motor due to subsequent multiple executions of a single wiping. At the same time, intermittent wiping can be restored according to the recorded remaining number of executions or the remaining execution time to avoid re-execution of intermittent wiping and avoid increase in motor temperature due to excessive execution of intermittent wiping.

[0116] In addition, during the intermittent wiping process, if it is detected that the user switches the wiper gear, the intermittent wiping can be suspended in response to the user's switch of gear to meet the user's needs and ensure the user's experience.

[0117] In one example, the method provided in the embodiment of the present application further includes the following steps:

[0118] Step 61: During the intermittent wiping process of the wiper, in response to receiving a wiper gear switching request initiated by a user, controlling the wiper to stop intermittent wiping;

[0119] Step 62: Determine a target gear of the wiper according to the wiper gear switching request, and control the operation of the wiper based on the target gear.

[0120] Among them, the wiper gear switching request can be generated when the user's wiper gear trigger operation is detected, for example, the user selects the gear by shaking the joystick or the user clicks the wiper gear on the vehicle interface.

[0121] Specifically, during the intermittent wiping process of the wiper, if a wiper gear switching request initiated by the user is detected, the wiper can be controlled to stop intermittent wiping, and then the target gear of the wiper is determined according to the wiper gear switching request, and the operation of the wiper is controlled according to the target gear. The target gear can be a low gear, a high gear, an automatic gear, etc.

[0122] Through the above example, during the intermittent wiping process, the user's needs can be detected in real time, and the operation of the wiper can be controlled according to the target gear required by the user, so that the wiper function can better meet the user's needs and ensure the user experience.

[0123] In the embodiment of the present application, taking into account the possibility that the vehicle is in parking gear and the user does not have a driving vision requirement, in this case, the single scraping request can be directly rejected and there is no need for intermittent scraping, so as to achieve the purpose of reducing the motor temperature.

[0124] In some implementations, before determining the intermittent wiping parameters of the wiper, the method further includes:

[0125] Get the current gear position of the vehicle;

[0126] In response to the current gear being a non-parking gear, determining an intermittent wiping parameter of the wiper;

[0127] In response to the current gear being the parking gear, the line of sight of the driver in the vehicle is determined based on a camera installed in the vehicle. If the line of sight of the driver is in the front of the vehicle, the step of determining the intermittent wiping parameters of the wiper is executed.

[0128] Specifically, in response to detecting that the number of single wiping requests received within a preset time reaches a preset number, the current gear of the vehicle can be obtained first. If the current gear is not in the parking gear, in order to ensure driving safety, the intermittent wiping parameters of the wiper can be further determined to achieve intermittent wiping.

[0129] If the current gear is in the parking gear, the driver's facial image can be further collected through the camera installed in the vehicle, and the driver's line of sight can be located through the facial image to obtain the driver's line of sight direction. If the driver's line of sight is in the front of the vehicle, it means that the user has a driving vision requirement, and the intermittent wiping parameters of the wiper can be determined at this time.

[0130] Through the above-mentioned implementation, in response to detecting that the number of single wiping requests received within the preset time reaches a preset number, intermittent wiping can be performed in a non-parking gear, and intermittent wiping can be performed when the car is in a parking gear and the driver's line of sight is forward. In the case where the car is in a parking gear and the user has no driving vision requirements, single wiping can be rejected and intermittent wiping is not required, thereby reducing the motor temperature.

[0131] The vehicle wiper control method provided in the embodiment of the present application determines the intermittent wiping parameters of the wiper in response to detecting that the number of single wiping requests received within a preset time reaches a preset number, and then controls the wiper to perform intermittent wiping according to the intermittent wiping parameters. The method can control the wiper to perform intermittent wiping when the wiper needs to perform single wiping multiple times, thereby avoiding continuous instantaneous starting current caused by multiple single wiping operations in a short period of time, thereby avoiding the wiper thermal protection function from being triggered and affecting the use of the wiper, ensuring that the user's driving field of view is not restricted, and improving the user's driving safety.

[0132] It should be noted that the method of the embodiment of the present application can be performed by a single device, such as a computer or server. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present application, and the multiple devices will interact with each other to complete the described method.
