To prevent damage to the wiper motor due to high temperatures, the wiper motor is typically operated at a reduced speed, with intermittent operation or even stopped completely.

[0056] Some embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be construed as limited to the embodiments described herein. Instead, these embodiments are provided to provide a more thorough and complete understanding of the present application. It should be understood that the drawings and embodiments of the present application are for illustrative purposes only and are not intended to limit the scope of protection of the present application.

[0057] It should be understood that the various steps described in the method embodiments of the present application can be performed in different orders and / or in parallel. In addition, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present application is not limited in this respect.

[0058] As used herein, the term "including" and its variations are open-ended, i.e., "including but not limited to." The term "based on" means "based, at least in part, on." The term "one embodiment" means "at least one embodiment," the term "another embodiment" means "at least one additional embodiment," and the term "some embodiments" means "at least some embodiments."

[0059] It should be noted that the concepts of "first" and "second" mentioned in this application are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0060] It should be noted that the modifications of "one" and "multiple" mentioned in this application are illustrative rather than restrictive. Those skilled in the art should understand that unless otherwise clearly indicated in the context, they should be understood as "one or more".

[0061] The names of the messages or information exchanged between multiple devices in some embodiments of the present application are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0062] After research, the applicant discovered that, to prevent the wiper motor from being damaged by high temperatures, related technologies use a method called downshifting when the temperature of the wiper motor's worm gear reaches a critical value. This involves reducing the wiper speed, intermittently driving, or completely shutting down the wiper. For example, as shown in Figure 1, when the electronic motor chip temperature (i.e., the worm gear temperature) reaches above 90°C, the wiper speed is reduced from a high speed of 60 r / min to a low speed of 40 r / min. When the electronic motor chip temperature reaches above 100°C, the wiper speed is reduced from a low speed of 40 r / min to an intermittent wipe every 2 seconds. When the electronic motor chip temperature reaches above 110°C, the wiper stops wiping. However, this results in a short duration of high-speed wiping (≥50 r / min), affecting the user's field of vision. This poses a significant risk to driving safety, especially in prolonged heavy rain conditions.

[0063] In order to solve the above problems, some embodiments of the present application provide a control method, device, equipment, medium and vehicle for a heat dissipation device.

[0064] FIG2 is a flow chart of a control method for a heat dissipation device provided in some embodiments of the present application.

[0065] In some embodiments of the present application, the control method of the heat dissipation device shown in Figure 2 can be executed by a control device of the heat dissipation device, which can be implemented by software and / or hardware. Exemplarily, the control device can be a controller on a vehicle, etc., but is not limited to this.

[0066] As shown in FIG2 , the control method of the heat dissipation device may include the following steps.

[0067] S210: Acquire the current temperature of the wiper motor and the current temperature of the power unit.

[0068] In an embodiment of the present application, a vehicle is provided with a heat dissipation device, a wiper motor and a power unit, wherein the wiper motor is used to drive the wipers to wipe the vehicle windshield. The power unit is used to output power and / or provide electrical energy to provide additional endurance. The power unit may include an engine, a range extender, a fuel cell and other devices, but is not limited thereto. The heat dissipation device is used to dissipate heat for the wiper motor and the power unit. It should be noted that those skilled in the art can arrange the specific distribution of the heat dissipation device, the wiper motor and the power unit according to actual conditions, as long as the heat dissipation device can dissipate heat for the wiper motor and the power unit. For example, as shown in FIG3 , the heat dissipation device, the power unit and the wiper motor are arranged in sequence along the direction from the front of the vehicle to the rear of the vehicle. In this way, when the heat dissipation device blows cold air toward the rear of the vehicle, it can dissipate heat for the wiper motor and the power unit together, but is not limited thereto.

[0069] In some embodiments of the present application, the control device can obtain the current temperature of the wiper motor (i.e., the temperature of the wiper motor at the current moment) and the current temperature of the power unit (i.e., the temperature of the power unit at the current moment), thereby determining the target opening degree of the heat dissipation device based on the current temperature of the wiper motor and the current temperature of the power unit. The specific manifestation of the target opening degree may include, but is not limited to, the fan speed, the duty cycle of the PWM (Pulse Width Modulation) signal used to drive the heat dissipation device, etc. It should be noted that the temperature of the wiper motor may include, for example, the temperature of the electronic motor chip in the wiper motor, and the current temperature of the power unit may include, for example, the temperature of the air intake duct in the power unit, etc., but is not limited to these.

[0070] Specifically, there are many ways to obtain the current temperature of the wiper motor and the current temperature of the power device. Typical examples are given below for illustration, but do not constitute a limitation to the present application.

[0071] In some embodiments, the current temperature of the wiper motor and the current temperature of the power device are collected by a temperature sensor, and S210 may include: receiving the current temperature of the wiper motor and the current temperature of the power device sent by the temperature sensor.

[0072] Specifically, the temperature sensor may include a thermometer, an infrared thermometer, etc., but is not limited thereto.

[0073] In other embodiments, S210 may include: obtaining the ambient temperature of the vehicle at the current moment, the wiping parameters of the wipers during the vehicle's current driving process from the start moment to the current moment, and the driving parameters of the vehicle during the current driving process from the start moment to the current moment, and inputting the three into a pre-trained first prediction model to obtain the current temperature of the wiper motor and the current temperature of the power unit output by the first prediction model.

[0074] Specifically, the wiping parameters may include wiping speed, etc., and the driving parameters may include vehicle speed, etc., but are not limited thereto.

[0075] S220: Determine a target opening degree of the heat dissipation device corresponding to the current temperature of the wiper motor and the current temperature of the power device.

[0076] In some embodiments, the higher the wiper motor temperature (or the temperature class to which the wiper motor temperature belongs), the greater the degree of opening of the heat dissipation device. Furthermore, the higher the power unit temperature (or the temperature class to which the power unit temperature belongs, with higher power unit temperatures belonging to higher temperature classes), the greater the degree of opening of the heat dissipation device. This allows for rapid reduction in the temperatures of the wiper motor and the power unit. Of course, in some embodiments, the degree of opening of the heat dissipation device can be fixed, meaning that regardless of the current wiper motor and power unit temperatures, the target degree of opening remains at a preset first fixed value. However, this is not limiting.

[0077] Specifically, there are many specific implementations of S220, and typical examples are described below, but they do not constitute a limitation to this application.

[0078] In some embodiments, S220 may include querying a preset second mapping relationship to determine a target opening degree corresponding to the current temperature of the wiper motor and the current temperature of the power unit. The second mapping relationship records the correspondence between the temperature of the wiper motor, the temperature of the power unit, and the opening degree of the heat dissipation device. In this way, the target opening degree can be simply, conveniently, and quickly obtained based on the current temperature of the wiper motor and the current temperature of the power unit.

[0079] In other embodiments, S220 may include: inputting the current temperature of the wiper motor and the current temperature of the power device into a pre-trained second prediction model, and obtaining the target opening degree output by the second prediction model.

[0080] In some further embodiments, S220 may include: S221, determining a first opening degree, wherein the first opening degree is determined based on the current temperature of the wiper motor; S222, determining a second opening degree corresponding to the current temperature of the power unit; S223, determining a target opening degree based on the first opening degree and the second opening degree.

[0081] Specifically, in some embodiments, the higher the wiper motor temperature (or the temperature level to which the wiper motor temperature belongs), the greater the first opening degree. Of course, in other embodiments, the first opening degree may also be fixed, that is, regardless of the current wiper motor temperature, the first opening degree remains at a preset fifth fixed value. However, this is not limiting.

[0082] In some embodiments, S221 may include: determining a temperature level to which the current temperature of the wiper motor belongs; and querying a preset fifth mapping relationship to determine a first opening degree corresponding to the temperature level to which the current temperature of the wiper motor belongs. In this way, the first opening degree can be obtained simply, conveniently, and quickly based on the current temperature of the wiper motor.

[0083] Specifically, S222 is similar to S432 below, and S223 is similar to S433 below, which will not be described in detail here.

[0084] S230: Control the heat dissipation device to operate at a target opening degree, wherein the heat dissipation device is used to dissipate heat for the wiper motor and the power device.

[0085] Specifically, the heat dissipation device may include a fan, an air conditioner, etc., but is not limited thereto.

[0086] It can be understood that when the heat dissipation device dissipates heat for the wiper motor and the power unit (for example, the heat dissipation device blows cold air to dissipate heat for the wiper motor and the power unit), it can not only reduce the temperature of the wiper motor itself, but also reduce the temperature of the power unit, thereby avoiding the power unit from transferring heat to the wiper motor to increase the temperature of the wiper motor. Therefore, the wiper itself can be quickly cooled down and dissipated, which is beneficial to extend the duration of high-speed wiping of the wiper.

[0087] Some embodiments of the present application can control the heat dissipation device to dissipate heat for the wiper motor and the power unit based on the current temperature of the wiper motor and the current temperature of the power unit, thereby quickly reducing the temperature of the wiper motor and the power unit and preventing the wiper motor and the power unit from being damaged due to temperature increases. In addition, the use of a heat dissipation device to dissipate heat for the wiper motor and the power unit can improve the efficiency of the heat dissipation device. In addition, compared with the prior art solution that does not use a heat dissipation device to dissipate heat for the wiper motor, some embodiments of the present application can use a heat dissipation device to dissipate heat for the wiper motor, thereby quickly reducing the temperature of the wiper motor itself and improving the problem of the wiper motor's wiping speed decreasing due to temperature increases. This is conducive to ensuring that the actual wiping speed of the wiper meets user requirements, timely clearing the user's field of view, and improving driving safety.

[0088] Figure 4 is a flow chart of another method for controlling a heat dissipation device provided by some embodiments of the present application. Some embodiments of the present application are optimized based on the above embodiments, and some embodiments of the present application can be combined with various optional solutions in one or more of the above embodiments.

[0089] As shown in FIG4 , the control method of the heat dissipation device may include the following steps.

[0090] S410: Acquire the current temperature of the wiper motor and the current temperature of the power unit.

[0091] Specifically, S410 is similar to S210 and will not be described again here.

[0092] S420: Obtain the current speed of the vehicle.

[0093] S430: Determine a target opening degree corresponding to a current temperature of the wiper motor, a current temperature of the power unit, and a current vehicle speed.

[0094] In some embodiments, the higher the temperature of the wiper motor (or the temperature level to which the temperature of the wiper motor belongs), the greater the degree of opening of the heat dissipation device; and / or, the higher the temperature of the power unit (or the temperature level to which the temperature of the power unit belongs), the greater the degree of opening of the heat dissipation device; and / or, the higher the speed of the vehicle (or the higher the vehicle level to which the vehicle speed belongs), the greater the degree of opening of the heat dissipation device. In this way, the temperature of the wiper motor and the temperature of the power unit can be quickly reduced. Of course, in other embodiments, the degree of opening of the heat dissipation device can also be fixed, that is, regardless of the current temperature of the wiper motor, the current temperature of the power unit, and the current speed of the vehicle, the target degree of opening is a preset second fixed value. However, this is not limited to this.

[0095] In some embodiments, S430 may include querying a preset third mapping relationship to determine a target opening degree corresponding to the current temperature of the wiper motor, the current temperature of the power unit, and the current vehicle speed. The third mapping relationship records the correspondence between the temperature of the wiper motor, the temperature of the power unit, the vehicle speed, and the opening degree of the heat dissipation device. In this way, the target opening degree can be simply, conveniently, and quickly obtained based on the current temperature of the wiper motor, the current temperature of the power unit, and the current vehicle speed.

[0096] In some other embodiments, S430 may include: S431, determining a first opening degree, wherein the first opening degree is determined based on a current vehicle speed and a current temperature of the wiper motor.

[0097] In some embodiments, the higher the wiper motor temperature (or the temperature class to which the wiper motor temperature belongs), the greater the first opening degree, and / or the higher the vehicle speed (or the speed class to which the vehicle speed belongs), the greater the first opening degree. Of course, in other embodiments, the first opening degree may also be fixed, that is, regardless of the current wiper motor temperature and the current vehicle speed, the first opening degree remains at a preset third fixed value. However, this is not limiting.

[0098] In some embodiments, S431 may include querying a preset first mapping relationship to determine a first opening degree corresponding to a speed level to which the current vehicle speed belongs and a temperature level to which the current temperature of the wiper motor belongs. In this way, the first opening degree can be simply, conveniently, and quickly obtained based on the current temperature of the wiper motor and the current vehicle speed.

[0099] Specifically, the higher the vehicle speed, the higher the speed level; and the higher the temperature of the wiper motor, the higher the temperature level.

[0100] Specifically, the first mapping relationship records the correspondence between the vehicle speed level, the temperature level of the wiper motor, and the opening degree of the heat dissipation device.

[0101] In some embodiments, in the first mapping relationship, there are at least two sets of mapping relationships (one corresponding vehicle speed level, one temperature level, and one opening degree constitutes a mapping relationship), and in these two sets of mapping relationships, for the same vehicle speed level, the opening degree corresponding to the higher temperature level is greater than the opening degree corresponding to the lower temperature level; and / or, in the first mapping relationship, there are at least two sets of mapping relationships, for the same temperature level, the opening degree corresponding to the higher speed level is greater than the opening degree corresponding to the lower speed level. This helps to ensure that the noise generated by the heat dissipation device does not exceed the noise generated by the vehicle running, or in other words, the difference between the noise generated by the heat dissipation device and the noise generated by the vehicle running is small. In this way, the overall noise of the vehicle can be relatively small, avoiding affecting the user experience.

[0102] Specifically, the specific content of the first mapping relationship can be set by those skilled in the art according to actual conditions and is not limited here. For example, the first mapping relationship is shown in Table 1. The opening degree of the heat dissipation device corresponding to the vehicle speed level "0" and the temperature level of the wiper motor "≤60℃" is "0%"; the opening degree of the heat dissipation device corresponding to the vehicle speed level "0" and the temperature level of the wiper motor ">60℃ and ≤80℃" is "60%"; the opening degree of the heat dissipation device corresponding to the vehicle speed level "0" and the temperature level of the wiper motor ">80℃ and <110℃" is "60%"; the opening degree of the heat dissipation device corresponding to the vehicle speed level "0" and the temperature level of the wiper motor "≥110℃" is "60%"; the opening degree of the heat dissipation device corresponding to the vehicle speed level "> The opening degree of the heat dissipation device corresponding to the speed level ">0 and <30" and the temperature level of the wiper motor "≤60℃" is "0%"; the opening degree of the heat dissipation device corresponding to the speed level ">0 and <30" and the temperature level of the wiper motor ">60℃ and ≤80℃" is "60%"; the opening degree of the heat dissipation device corresponding to the speed level ">0 and <30" and the temperature level of the wiper motor ">80℃ and <110℃" is "80%"; the opening degree of the heat dissipation device corresponding to the speed level ">0 and <30" and the temperature level of the wiper motor "≥110℃" is "80%"; the opening degree of the heat dissipation device corresponding to the speed level ">0 and <30" and the temperature level of the wiper motor "≥110℃" is "80%"; the opening degree of the heat dissipation device corresponding to the speed level ">0 and <30" and the temperature level of the wiper motor "≥110℃" is "80%"; the opening degree of the heat dissipation device corresponding to the speed level The opening degree of the heat dissipation device corresponding to the speed level "≥30 and <60" and the temperature level of the wiper motor "≤60℃" is "0%"; the opening degree of the heat dissipation device corresponding to the speed level "≥30 and <60" and the temperature level of the wiper motor ">60℃ and ≤80℃" is "60%"; the opening degree of the heat dissipation device corresponding to the speed level "≥30 and <60" and the temperature level of the wiper motor ">80℃ and <110℃" is "80%"; the opening degree of the heat dissipation device corresponding to the speed level "≥30 and <60" and the temperature level of the wiper motor "≥110℃" is "80%"; the opening degree of the heat dissipation device corresponding to the speed level "≥60 The opening degree of the heat dissipation device corresponding to the vehicle speed level "≥60 and ≤90" and the temperature level of the wiper motor "≤60℃" is "0%"; the opening degree of the heat dissipation device corresponding to the vehicle speed level "≥60 and ≤90" and the temperature level of the wiper motor ">60℃ and ≤80℃" is "60%"; the opening degree of the heat dissipation device corresponding to the vehicle speed level "≥60 and ≤90" and the temperature level of the wiper motor ">80℃ and <110℃" is "80%"; the opening degree of the heat dissipation device corresponding to the vehicle speed level "≥60 and ≤90" and the temperature level of the wiper motor "≥110℃", but not limited to this.

[0103] Table 1 First mapping relationship between vehicle speed level, wiper motor temperature level, and heat sink opening degree

[0104] In some embodiments, when the wiper motor temperature remains constant, the higher the vehicle speed, the greater the degree of opening of the heat dissipation device. Accordingly, in the first mapping relationship, when the wiper motor temperature level remains constant, the higher the vehicle speed level, the greater the corresponding opening degree. Of course, the first mapping relationship can also be configured such that, when the vehicle speed level remains constant, the higher the wiper motor temperature level, the greater the corresponding opening degree.

[0105] In some embodiments, S431 may include: inputting the vehicle speed and the current temperature of the wiper motor into a pre-trained third prediction model, and obtaining a first opening degree output by the third prediction model.

[0106] S432: Determine a second opening degree corresponding to the current temperature of the power device.

[0107] In some embodiments, the higher the temperature of the power device (or the temperature level to which the temperature of the power device belongs), the greater the second opening degree. Of course, in other embodiments, the second opening degree can also be fixed, that is, regardless of the current temperature of the power device, the second opening degree is always a preset fourth fixed value. However, this is not limited to this.

[0108] In some embodiments, S432 may include: querying a preset fourth mapping relationship to determine a second opening degree corresponding to the current temperature of the power device, wherein the fourth mapping relationship records the correspondence between the temperature of the power device and the opening degree of the heat dissipation device.

[0109] In some embodiments, S432 may include: inputting the current temperature of the power device into a pre-trained fourth prediction model, and obtaining a second opening degree output by the fourth prediction model.

[0110] S433: Determine a target opening degree according to the first opening degree and the second opening degree.

[0111] In some embodiments, S2223 may include setting the larger of the first opening degree and the second opening degree as the target opening degree. This not only satisfies the heat dissipation requirements of the wiper motor, achieving rapid cooling of the wiper motor, but also satisfies the heat dissipation requirements of the power unit, reducing the risk of heat transfer from the power unit to the wiper motor, thereby affecting the cooling of the wiper motor.

[0112] In some other embodiments, S2223 may include: performing weighted summation on the first opening degree and the second opening degree to obtain a sum value; and using the sum value as the target opening degree.

[0113] In some embodiments, the weight coefficient of the first opening degree is greater than the weight coefficient of the second opening degree. In this way, the heat dissipation requirement of the wiper motor can be preferably met, and the wiper motor can be quickly cooled.

[0114] Of course, the weight coefficient of the first opening degree can also be less than or equal to the weight coefficient of the second opening degree. In this way, the wiper motor can be cooled to a certain extent, and the cooling requirements of the power unit can be preferentially met, thereby reducing the risk of the power unit transferring heat to the wiper motor and affecting the cooling of the wiper motor.

[0115] In some further embodiments, S2223 may include: if the current temperature of the wiper motor is greater than a preset temperature threshold, using the first opening degree as the target opening degree; if the current temperature of the wiper motor is less than or equal to the preset temperature threshold, using the second opening degree as the target opening degree.

[0116] Specifically, the specific value of the preset temperature threshold can be set by those skilled in the art according to actual conditions and is not limited here.

[0117] It is understood that when the current temperature of the wiper motor is greater than the preset temperature threshold, it indicates that the current temperature of the wiper motor is high and heat dissipation is urgently needed, otherwise the wiping speed of the wiper motor may be seriously affected. In this case, using the first opening degree as the target opening degree can prioritize meeting the heat dissipation requirements of the wiper motor, achieving rapid cooling of the wiper motor, and thus minimizing the impact of the wiper motor temperature on the wiping speed of the wiper motor. When the current temperature of the wiper motor is less than or equal to the preset temperature threshold, it indicates that the current temperature of the wiper motor is low and the heat dissipation requirement is not urgent. In this case, using the second opening degree as the target opening degree can prioritize meeting the heat dissipation requirements of the power unit, reducing the risk of the power unit transferring heat to the wiper motor and affecting the cooling of the wiper motor.

[0118] S440: Control the heat dissipation device to operate at a target opening degree, wherein the heat dissipation device is used to dissipate heat for the wiper motor and the power device.

[0119] Specifically, S440 is similar to S230 and will not be described again here.

[0120] In some embodiments of the present application, taking into account that during the driving of a vehicle, there will usually be noises such as wind noise, tire noise, and engine noise caused by the driving of the vehicle, and the greater the speed of the vehicle, the greater the noise generated by the driving of the vehicle. By setting the target opening degree based on the current temperature of the wiper motor, the current temperature of the power unit, and the current vehicle speed, the noise generated by the heat dissipation device can be made not to exceed the noise generated by the driving of the vehicle, or the difference between the noise generated by the heat dissipation device and the noise generated by the driving of the vehicle can be made smaller. In this way, the overall noise of the vehicle can be made relatively small, avoiding affecting the user experience.

[0121] In order to prove that the embodiments of the present application can quickly reduce the temperature of the wiper motor, a comparative experiment was conducted on some embodiments of the present application. The only difference between the experimental group and the control group is that the experimental group used a heat dissipation device to dissipate heat from the wiper motor, and the control group did not use a heat dissipation device to dissipate heat from the wiper motor. The experimental results are shown in Figure 5. It can be seen that the control method provided by some embodiments of the present application is used to control the heat dissipation device to dissipate heat from the wiper motor, which can effectively reduce the temperature of the wiper motor, thereby reducing the impact of the wiper motor on the wiping speed due to the increase in temperature, which is beneficial to extending the duration of high-speed wiping of the wiper.
