When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0030] A first aspect of the present application provides a vehicle wiper motor control method. Figure 1 1 is a flow chart of an embodiment of a vehicle wiper motor control method provided by the present application. Figure 1 , the method comprises the following steps:

[0031] S101: When it is detected that the wiper motor of the vehicle is in working state, the current temperature of the wiper motor is obtained.

[0032] In some application scenarios, the user can manually start the wiper motor, for example, by using a wiper switch, so that the wipers on the front windshield can be wiped to ensure a good field of vision. In other application scenarios, the current rainfall can be detected by a rain detection device, and when the rainfall is detected to be greater than a certain amount, the wiper motor can be automatically started.

[0033] This step focuses on the operating temperature of the wiper motor during operation. When the wiper motor is detected to be in working state, the current temperature of the wiper motor is obtained. The current temperature of the wiper motor can be obtained at a certain frequency during the entire operation of the wiper motor. For example, the current temperature of the wiper motor can be obtained every 5 seconds.

[0034] Specifically, a temperature sensor may be provided inside the wiper motor, and the temperature inside the wiper motor is detected by the temperature sensor as the current temperature, so that the current temperature can better reflect the temperature condition inside the wiper motor.

[0035] S102: If the current temperature of the wiper motor is higher than the first preset temperature, the current water temperature of the engine radiator of the vehicle is obtained.

[0036] The first preset temperature can be set according to actual application scenarios and requirements, and the first preset temperature can be a relatively high temperature when the wiper motor is working. When the current temperature of the wiper motor is higher than the first preset temperature, it means that the current working temperature of the wiper motor is high. If this working state is maintained for a long time or the temperature rises further, the wiper motor is likely to work abnormally or be damaged.

[0037] Therefore, when the current temperature of the wiper motor is higher than the first preset temperature, it is necessary to consider better heat dissipation of the wiper motor to reduce the operating temperature of the wiper motor. In this embodiment, the wiper motor is cooled by the airflow of the front cooling fan. In this step, the current water temperature of the engine radiator is first obtained to further understand whether the airflow formed by the front cooling fan is suitable for cooling the wiper motor.

[0038] S103: If the current water temperature of the engine radiator is lower than the first preset temperature, the current power of the front cooling fan of the vehicle is controlled to reach the target power, so as to dissipate the heat of the wiper motor through the airflow formed by the front cooling fan.

[0039] It should be understood that if the airflow formed by the front cooling fan is required to be blown to the wiper motor to dissipate the heat of the wiper motor, the airflow formed by the front cooling fan will first pass through the engine radiator. When the airflow passes through the engine radiator, if the engine radiator is working, the engine radiator will heat the airflow to increase the temperature of the airflow, but the temperature of the heated airflow will not be higher than the water temperature of the engine radiator.

[0040] If the current water temperature of the engine radiator is lower than the first preset temperature, it means that the temperature of the airflow passing through the engine radiator will not be higher than the first preset temperature. At this time, the wiper motor can be cooled by the airflow formed by the front cooling fan. It should be understood that there is a certain distance between the wiper motor and the front cooling fan. In order to ensure that the airflow formed by the front cooling fan can blow to the wiper motor, the wind force of the front cooling fan needs to be large enough, that is, the current power of the front cooling fan needs to reach the target power. Among them, the target power can be determined in advance by calibration.

[0041] In summary, when the current temperature of the wiper motor is higher than the first preset temperature, it means that the current temperature of the wiper motor is high, and when the current water temperature of the engine radiator is lower than the first preset temperature, it means that the airflow temperature formed by the front cooling fan is low. At this time, the wiper motor is cooled by the airflow, which can achieve good heat dissipation for the wiper motor and enable the wiper motor to work normally.

[0042] Figure 2 It is a flow chart of another embodiment of the vehicle wiper motor control method provided in the present application.

[0043] Combination Figure 2 In some specific embodiments, if the current water temperature of the engine radiator is lower than the first preset temperature, the current power of the front cooling fan of the vehicle is controlled to reach the target power so as to dissipate the heat of the wiper motor through the airflow formed by the front cooling fan, that is, after the above step S103, the method includes:

[0044] S201: If the current temperature of the wiper motor is unchanged or decreasing, the front cooling fan is controlled to maintain the current power.

[0045] It should be understood that the serial numbers of the steps in this embodiment do not limit the execution order of the steps.

[0046] When the wiper motor is cooled by the airflow formed by the front cooling fan, the heat dissipation level of the wiper motor is improved. At this time, the current temperature of the wiper motor is likely not to rise, that is, it is likely to remain unchanged or decrease. When it is unchanged or decreased, it means that the heat dissipation of the wiper motor is good, and there is no need to further improve the heat dissipation level of the wiper motor, that is, the current power of the front cooling fan can be maintained, that is, the size of the airflow formed by the front cooling fan can be maintained.

[0047] Among them, after the wiper motor is cooled by the airflow of the front-end cooling fan, the various temperature values ​​collected at preset time intervals can be compared, and then the current temperature state of the wiper motor can be determined through temperature comparison.

[0048] S202: If the current temperature of the wiper motor is in an elevated state, the front cooling fan is controlled to increase the current power.

[0049] When the wiper motor is cooled by the front cooling fan, although the heat dissipation level of the wiper motor is improved, the current temperature of the wiper motor may still be in an elevated state.

[0050] At this time, it is necessary to further improve the heat dissipation effect of the wiper motor. The front-end cooling fan can be controlled to increase the current power to increase the air flow formed by the front-end cooling fan, thereby improving the heat dissipation effect of the wiper motor.

[0051] Figure 3 It is a flow chart of another embodiment of the vehicle wiper motor control method provided in the present application.

[0052] Combination Figure 3 In some specific embodiments, if the current temperature of the wiper motor is in an elevated state, after the step of controlling the front cooling fan to increase the current power, that is, after the above step S202, the following steps are included:

[0053] S301: If the current power of the front cooling fan reaches the preset maximum power and the current temperature of the wiper motor is in an elevated state, the current power of the engine of the vehicle is controlled to decrease.

[0054] In combination with the above content, if the current temperature of the wiper motor is in an elevated state, the current power of the front cooling fan will be increased. If the current temperature of the wiper motor continues to rise, the current power of the front cooling fan will continue to increase until the current power of the front cooling fan reaches the preset maximum power. The preset maximum power is set in advance according to the actual application scenario and actual needs.

[0055] When the current power of the front cooling fan reaches the preset maximum power, the heat dissipation effect of the wiper motor can no longer be improved by increasing the power of the front cooling fan. At this time, if the current temperature of the wiper motor is in an elevated state, in order to improve the heat dissipation effect of the wiper motor, the temperature of the airflow is reduced by controlling the current power of the engine to improve the heat dissipation effect of the wiper motor. It should be understood that when the power of the engine is reduced, the heat dissipation pressure of the engine radiator is reduced, so that the water temperature of the engine radiator is reduced, the temperature of the airflow passing through the engine radiator will be reduced, and the temperature of the airflow reaching the wiper motor will be reduced, so as to improve the heat dissipation effect of the wiper motor.

[0056] In some application scenarios, the vehicle is a range-extended vehicle, which generates electricity through the engine to provide driving power for the vehicle's drive motor. At this time, when the engine power decreases, the output power decreases. In order to ensure that the power of the drive motor does not decrease, it is necessary to increase the amount of electricity output by the battery pack to the drive motor per unit time.

[0057] S302: When it is detected that the current temperature of the wiper motor drops below a first preset temperature, the current power of the engine is controlled to increase.

[0058] The above steps improve the heat dissipation effect of the wiper motor by reducing the power of the engine, and there is a high probability that the current temperature of the wiper motor will be reduced.

[0059] If the current temperature of the wiper motor drops below the first preset temperature, it means that the wiper motor is no longer operating at a high temperature, and it is not necessary to effectively dissipate heat for the wiper motor through the above-mentioned measures. Therefore, in order to ensure sufficient power of the engine, the current power of the engine can be controlled to increase when necessary.

[0060] Figure 4 It is a flow chart of another embodiment of the vehicle wiper motor control method provided in the present application.

[0061] Combination Figure 4 In some specific embodiments, after detecting that the wiper motor of the vehicle is in working state, the step of obtaining the current temperature of the wiper motor, that is, after the above step S101, includes:

[0062] S401: If the current temperature of the wiper motor is higher than a second preset temperature, the current operating stroke of the wiper motor is controlled to increase to a preset operating stroke so that water scraped off by the wipers flows through preset water holes to the wiper motor to dissipate heat; wherein the second preset temperature is higher than the first preset temperature.

[0063] The second preset temperature is preset so that the second preset temperature is higher than the first preset temperature, but the temperature difference between the second preset temperature and the first preset temperature is not too large.

[0064] If the current temperature of the wiper motor is higher than the second preset temperature, it means that the temperature of the wiper motor is relatively high and the wiper motor needs to be well cooled. This embodiment further introduces a method of cooling the wiper motor by water flowing down the water flow hole.

[0065] It should be understood that the water flow hole is set on the cover plate of the front engine compartment of the vehicle. If the water flow hole is not set on the cover plate of the front engine compartment, then a water flow hole needs to be opened. The water flowing down from the water flow hole can be introduced to the top of the wiper motor, and then flow down from the top of the wiper motor to achieve heat dissipation of the wiper motor. Among them, a filter body such as a sponge can be set on the top of the wiper motor, so that the water flowing out of the water flow hole is filtered by the filter body to dissipate the heat of the wiper motor, thereby preventing impurities from affecting the operation of the wiper motor.

[0066] In most application scenarios, the wiper motor has an insufficient stroke, which results in an insufficient wiping stroke of the wiper, so that the water scraped by the wiper motor will not flow to the water flow hole in large quantities. This embodiment increases the current operating stroke of the wiper motor to the preset operating stroke, thereby increasing the stroke of the wiper, thereby scraping more water to the water flow hole, and then the wiper motor is well cooled by the large amount of water flowing through the water flow hole. Among them, the operating stroke of the wiper motor can be increased by increasing the power of the wiper motor, but of course it is not limited to this. Among them, the preset operating stroke is set according to demand, and it is sufficient to be able to scrape more water to the water flow hole under the preset operating stroke.

[0067] It should be understood that the heat dissipation method provided in this embodiment can be used together with the related methods of the above embodiments, or can be used after the related steps of the above embodiments, without specific limitation. For example, when the current temperature of the wiper motor is higher than the second preset temperature, the wiper motor can be cooled by the airflow formed by the front cooling fan, and the wiper motor can be cooled by increasing the stroke of the wiper motor.

[0068] Figure 5 It is a flow chart of another embodiment of the vehicle wiper motor control method provided in the present application.

[0069] Combination Figure 5 In some specific embodiments, after detecting that the wiper motor of the vehicle is in working state, the step of obtaining the current temperature of the wiper motor, that is, after the above step S101, includes:

[0070] S501: If the current temperature of the wiper motor is higher than the third preset temperature, the current power of the wiper motor is reduced to the current minimum power; wherein the current minimum power is the minimum power corresponding to the wiper motor when the front windshield meets the preset visibility under the current rainfall, and the third preset temperature is higher than the first preset temperature.

[0071] The third preset temperature is set in advance according to actual needs, and the difference between the third preset temperature and the first preset temperature is not too large. In addition, the third preset temperature is higher than the second preset temperature, and the difference between the third preset temperature and the second preset temperature is not too large.

[0072] If the current temperature of the wiper motor is higher than the third preset temperature, it means that the operating temperature of the wiper motor is relatively high. This embodiment reduces the current temperature of the wiper motor by reducing the current power of the wiper motor to reduce the heat generated by the wiper motor.

[0073] When the current minimum temperature of the wiper motor is determined, the current rainfall can be obtained, and the minimum wiping frequency of the wiper motor can be determined according to the current rainfall, and then the current minimum power of the wiper motor can be determined according to the minimum wiping frequency.

[0074] In this way, the current power of the wiper motor is reduced, thereby reducing the heat, while meeting the basic wiper needs to meet basic visibility and ensure driving safety.

[0075] Likewise, this embodiment can be combined with the above embodiment, or after the above embodiment. For example, when the current temperature of the wiper motor is higher than the third preset temperature, the wiper motor can be cooled by the front cooling fan and the water flow hole.

[0076] In some specific embodiments, the wiper motor includes a first wiper motor and a second wiper motor. The first wiper motor and the second wiper motor are respectively used to drive different wipers, and the first wiper motor and the second wiper motor are arranged at different positions.

[0077] Figure 6 It is a flow chart of another embodiment of the vehicle wiper motor control method provided in the present application.

[0078] Combination Figure 6 , after detecting that the wiper motor of the vehicle is in working state, the step of obtaining the current temperature of the wiper motor, that is, after the above step S101, includes:

[0079] S601: If at least one of the current temperatures of the first wiper motor and the second wiper motor is higher than a fourth preset temperature, the first wiper motor with a higher current temperature is controlled to shut down, and the second wiper motor with a lower current temperature is controlled to continue running; wherein the fourth preset temperature is higher than the first preset temperature.

[0080] The fourth preset temperature is higher than the third preset temperature, the third preset temperature is higher than the second preset temperature, and the second preset temperature is higher than the first preset temperature.

[0081] It should be understood that since the first wiper motor and the second wiper motor are arranged at different positions, the first wiper motor and the second wiper motor are affected differently by the hot air flow in the cabin, which will lead to inconsistent temperatures of the first wiper motor and the second wiper motor. In addition, the operating temperature of the one that is more seriously affected by the hot air flow will be higher than that of the other.

[0082] When at least one of the current temperatures of the first wiper motor and the second wiper motor is higher than the fourth preset temperature, it means that the temperature of at least one wiper motor is very high. Assume that the temperature of the first wiper motor is higher than that of the second wiper motor. At this time, in order to ensure that the first wiper motor with a high temperature will not be damaged, the first wiper motor is controlled to shut down. In order to ensure the normal wiping of the rain, the second wiper motor will be controlled to continue to run. Therefore, through this setting method, a wiper motor with a very high temperature can be shut down to avoid damage to its work, and the wiping function can be maintained by the work of the other wiper motor.

[0083] In some application scenarios, when at least one of the current temperatures of the first wiper motor and the second wiper motor is higher than the fourth preset temperature, the vehicle may be in an environment with heavy rainfall. At this time, the operation of the second wiper motor alone may not provide the driver with a good field of view, and there are certain safety hazards. In order to solve this safety hazard, the shutdown time of the first wiper motor can be controlled to be less than the preset time, and after the first wiper motor resumes operation, when it is detected that the temperature of the first wiper motor is still higher than the fourth preset temperature, a relevant warning message is issued. The preset time can be a shorter time. Alternatively, this step can detect the amount of rainfall at the same time, and only when it is detected that the current rainfall is less than the preset rainfall, the step of controlling the first wiper motor to shut down is executed.

[0084] Figure 7 It is a flow chart of another embodiment of the vehicle wiper motor control method provided in the present application.

[0085] Combination Figure 7 In some specific embodiments, after the step of controlling the first wiper motor with a higher current temperature to stop and controlling the second wiper motor with a lower current temperature to continue to operate, that is, after the above step S601, the method includes:

[0086] S701: When it is detected that the current temperature of the first wiper motor drops to a second preset temperature, the first wiper motor is controlled to operate and the second wiper motor is controlled to stop; wherein the second preset temperature is lower than a fourth preset temperature.

[0087] In combination with the above content, the first wiper motor with a higher temperature will shut down, but will not remain in the shutdown state. As long as the current temperature of the first wiper motor drops to the second preset temperature, it will restart. At this time, the temperature of the second wiper motor is generally higher, so the second wiper motor is controlled to shut down.

[0088] It should be understood that the second preset temperature may be the second preset temperature involved in the above embodiment. When the current temperature of the first wiper motor is reduced to the second preset temperature, it indicates that the temperature of the first wiper motor is significantly reduced. At this time, the first wiper motor will not work abnormally in a short time. In addition, since the second wiper motor continues to work, its temperature may rise to a higher temperature. In order to avoid the abnormal operation of the second wiper motor, the second wiper motor is stopped to dissipate heat.

[0089] S702: When it is detected that the temperature of the second wiper motor is higher than a fifth preset temperature, over-temperature information and parking information are generated to remind the user; wherein the fifth preset temperature is higher than the fourth preset temperature.

[0090] It should be understood that the arrangement order of the steps in this embodiment does not limit the execution order of the steps.

[0091] In combination with the above, after the first wiper motor with a higher temperature stops, the second wiper motor still works. If the temperature of the first wiper motor does not drop to the second preset temperature, the temperature of the second wiper motor is higher than the fifth preset temperature, indicating that the temperature of the second wiper motor has reached a very high temperature. If it continues to work, the motor will be damaged and the vehicle will lose the wiper function.

[0092] In order to ensure that the wiper motor is not damaged and to ensure safe driving of the vehicle, the present embodiment generates over-temperature information of the wiper motor to remind the user, and generates parking information to remind the user to pull over.
