Technical Field
[0001] This application relates to the field of vehicle control technology, and more specifically, to a vehicle control method, device, and vehicle in the field of vehicle control. Background Technology
[0002] In winter, after parking a car, the large temperature difference between the interior and exterior can easily cause frost to form on the windshield. When the driver needs to use the car, they have to manually defrost or activate the defrosting function, resulting in a poor user experience. However, not manually defrosting can compromise driving safety. Therefore, preventing windshield frost in winter is a problem that needs to be addressed. Summary of the Invention
[0003] This application provides a vehicle control method, device, and vehicle. The method can select a target anti-frost strategy that is adapted to the weather information of the vehicle's environment to ensure that the windshield can be prevented from frosting in that weather.
[0004] Firstly, a method for controlling a vehicle is provided, the method comprising: If a risk of frost forming on the vehicle's windshield is detected, obtain weather information about the vehicle's surroundings. Determine whether the vehicle is in snowy weather based on the weather information; If the vehicle is in a snowy weather environment, the target anti-frost strategy is determined based on the amount of snowfall. The target anti-frost strategy includes the degree to which the vehicle windows are open and the mode of the vehicle's air conditioning. Control the vehicle to execute the target anti-frost strategy.
[0005] In the above technical solution, since vehicle windshields are more prone to frost formation in snowy weather, and the rate of frost formation varies with different amounts of snowfall, determining the target anti-frost strategy based on the amount of snowfall in snowy weather allows for the selection of a target anti-frost strategy that is suitable for the current environment of the vehicle, ensuring that windshield frost can be prevented under that amount of snowfall.
[0006] In conjunction with the first aspect, among some possible implementations, the above-mentioned strategy for determining the target anti-frost based on snowfall during snowfall weather includes: If the snowfall is within the first preset snowfall range, the target anti-frost strategy includes: opening the windows at a preset opening degree, setting the air conditioning to external circulation mode, directing the air conditioning airflow towards the first and second directions, and rotating the air conditioning blower clockwise at the first setting. If the snowfall is within the second preset snowfall range, the target anti-frost strategy includes: the windows are closed, the air conditioning is in external circulation mode, the air conditioning airflow is directed in the first direction, and the blower is rotating clockwise in the second gear; wherein, the starting value of the second preset snowfall range is greater than the ending value of the first preset snowfall range; the first direction is used to indicate the bottom of the vehicle's cabin, and the second direction is used to indicate the direction of the windshield; the speed of the first gear is less than the speed of the second gear.
[0007] In the above technical solution, when the snowfall is within the first preset snowfall range (e.g., light snow), the air conditioner is in external circulation mode, the airflow is directed towards the first and second directions (e.g., the bottom of the vehicle's cabin and the direction of the windshield), and the blower is rotated clockwise. This can blow the cold air from outside the vehicle towards the bottom of the cabin and the windshield, causing the temperature inside the vehicle and the windshield to drop. At the same time, by opening the windows, the hot air inside the vehicle is expelled, achieving rapid cooling of the vehicle's interior and thus preventing frost from forming on the windshield.
[0008] In addition, when the snowfall is within the second preset snowfall range (e.g., heavy snow), the air conditioner directs the airflow in the first direction and the blower rotates to the second setting, which can blow more cold air into the vehicle interior, allowing the vehicle interior to cool down quickly and preventing the windshield from frosting.
[0009] In combination with the first aspect and the above implementation methods, in some possible implementation methods, if the snowfall is within the first preset snowfall range, determining the target anti-frost strategy also includes: If the first temperature difference is less than the first preset threshold and the second temperature difference is less than the second preset threshold, the windows are closed, and the air conditioning mode is switched to the target air conditioning mode. Here, the first temperature difference is the temperature difference between the inside and outside of the vehicle at the current moment; the second temperature difference is the temperature difference between the outside of the vehicle and the inside of the windshield; the first preset threshold is greater than the second preset threshold; and the target air conditioning mode is the mode of the air conditioning in the vehicle before switching to the target anti-frost strategy. If the snowfall amount falls within the second snowfall range, the target anti-frost strategy also includes: After a preset time, the air conditioner directs the airflow towards the third direction, and the blower rotates counterclockwise in the second position. The third direction refers to the top of the vehicle's cabin. If the third temperature difference is less than the third preset threshold, the air conditioner directs the airflow towards the second direction, and the blower rotates clockwise in the third position. If the fourth temperature difference is less than the fourth preset threshold, the air conditioner is set to the target air conditioning mode. The third temperature difference is the temperature difference between the inside and outside of the vehicle at the current moment, the fourth temperature difference is the temperature difference between the inside of the windshield and the outside of the vehicle at the current moment, the third preset threshold is greater than the fourth preset threshold, and the speed in the third position is less than the speed in the second position.
[0010] In the above technical solution, when the first temperature difference is less than the first preset threshold and the second temperature difference is less than the second preset threshold, or when the fourth temperature difference is less than the fourth preset threshold, it indicates that the windshield is not prone to frost formation. At this time, keeping the windows closed ensures vehicle safety. Switching the air conditioning mode to the mode before the target anti-frost strategy is implemented ensures that when the owner restarts the vehicle, the previously set air conditioning mode will be restored, improving the user experience.
[0011] In addition, the wind direction is towards the top of the vehicle's cockpit, and the blower rotates counterclockwise; this can expel the rising hot air from the outside of the vehicle, enabling the interior of the vehicle to cool down quickly; when the third temperature difference is less than the third preset threshold, it indicates that the interior temperature of the vehicle is low; at this time, the wind direction is towards the windshield, which can enable the windshield to cool down quickly, thereby preventing the windshield from frosting.
[0012] In addition, when the interior of the vehicle is already mostly cold air, the blower can be turned on at a third speed, which is lower than the second speed, to quickly cool down the windshield, saving energy and preventing frost from forming on the windshield.
[0013] Combining the first aspect and the above implementation methods, in some possible implementation methods, the target anti-frost strategy is determined based on the amount of snowfall during snowfall weather, including: If snowfall and rainfall are detected, the target anti-frost strategy is determined to include: the windows are closed, the air conditioning is in external circulation mode, the air conditioning airflow is directed in the first direction, and the air conditioning blower is rotating clockwise in the second position. The first direction is used to indicate the bottom of the vehicle's cabin.
[0014] In the above technical solution, if snowfall and rainfall are detected, it indicates that the weather is rainy and snowy, and the windshield is more prone to frost formation. With the wind direction in the first direction and the blower in the second gear, more cold air can be blown into the vehicle, allowing the vehicle interior to cool down quickly and preventing the windshield from frost formation.
[0015] Combining the first aspect and the above implementation methods, in some possible implementation methods, if snowfall and rainfall are detected, determining the target anti-frost strategy also includes: After a preset time, the air conditioner directs the airflow towards a third direction, and the blower rotates counterclockwise at the second setting; the third direction indicates the top of the vehicle's cabin; if the third temperature difference is less than the third preset threshold, the air conditioner directs the airflow towards a second direction, and the blower rotates clockwise at the third setting; the second direction indicates the direction of the windshield; if the fourth temperature difference is less than the fourth preset threshold, the air conditioner mode is the target air conditioner mode, which is the mode of the vehicle's air conditioner before switching to the target anti-frost strategy; wherein, the third temperature difference is the temperature difference between the inside and outside of the vehicle at the current moment, the fourth temperature difference is the temperature difference between the inside of the windshield and the outside of the vehicle at the current moment, the third preset threshold is greater than the fourth preset threshold, and the speed at the third setting is less than the speed at the second setting.
[0016] In the above technical solution, after a preset time, the airflow is directed towards the top of the vehicle's cabin, and the blower rotates counterclockwise; this can expel the rising hot air from the vehicle, enabling rapid cooling of the vehicle's interior; when the third temperature difference is less than the third preset threshold, it indicates that the vehicle's interior temperature is low; at this time, the airflow is directed towards the windshield, enabling rapid cooling of the windshield and thus preventing frost formation; when the fourth temperature difference is less than the fourth preset threshold, it indicates that the windshield is less prone to frost formation, and the air conditioning mode is switched to the air conditioning mode before the target anti-frost strategy was implemented, ensuring that when the owner restarts the vehicle, the air conditioning will resume the previously set air conditioning mode, improving the user experience.
[0017] In combination with the first aspect and the above implementation methods, some possible implementation methods also include: If the vehicle is not in snowy weather, control the windows and sunroof to open at the preset opening degree, adjust the vehicle's air conditioning circulation mode to external circulation mode, direct the air conditioning airflow towards the first and second directions, and rotate the air conditioning blower clockwise at the fourth position; where the first direction is used to indicate the bottom of the vehicle's cabin, and the second direction is used to indicate the direction of the windshield.
[0018] In the above technical solution, when the vehicle is in a non-snowy weather environment, opening the windows and sunroof ensures rapid cooling of the vehicle; secondly, the air conditioning is directed towards the first and second directions, which enables the vehicle interior and windshield to cool down rapidly at the same time, preventing frost from forming on the windshield.
[0019] Combining the first aspect and the above implementation methods, in some possible implementation methods, when a risk of frost formation on the vehicle's windshield is detected, weather information about the vehicle's environment is obtained, including: Obtain a first temperature value inside the vehicle, a second temperature value outside the vehicle, and a third temperature value inside the windshield; if the first temperature value is greater than a first preset temperature value, the second temperature value is less than a second preset temperature value, and the third temperature value is greater than a third preset temperature value, obtain the weather information of the vehicle's environment.
[0020] In the above technical solution, since the temperature value of the inside of the windshield is between the temperature inside the vehicle and the temperature outside the vehicle, the presence of frost risk on the windshield can be determined by combining the temperature values inside the vehicle, the temperature values outside the vehicle, and the temperature value of the inside of the windshield, which can improve the accuracy of the obtained frost risk.

[0022] In the above technical solution, when the battery level is greater than the preset battery level, obtaining the first temperature value, the second temperature value, and the third temperature value can ensure that the process of preventing frost formation will not affect the normal driving of the vehicle.
[0023] Secondly, a vehicle control device is provided, the device comprising: The first acquisition module is used to acquire weather information about the vehicle's environment when a risk of frost forming on the vehicle's windshield is detected. The first determination module is used to determine whether the vehicle's environment is snowy based on weather information; The second determining module is used to determine the target anti-frost strategy based on the amount of snowfall if the vehicle is in snowy weather.

If the snowfall is within the second preset snowfall range, the target anti-frost strategy includes: the windows are closed, the air conditioning is in external circulation mode, the air conditioning airflow is directed in the first direction, and the blower is rotating clockwise in the second gear; wherein, the starting value of the second preset snowfall range is greater than the ending value of the first preset snowfall range; the first direction is used to indicate the bottom of the vehicle's cabin, and the second direction is used to indicate the direction of the windshield; the speed of the first gear is less than the speed of the second gear.
[0025] In combination with the second aspect and the above implementation, in some possible implementations, the device further includes a third determining module, used to determine the target anti-frost strategy if the snowfall amount is within the first preset snowfall amount range. The strategy further includes: if the first temperature difference is less than the first preset threshold and the second temperature difference is less than the second preset threshold, the window is closed, and the air conditioning mode is switched to the target air conditioning mode. The first temperature difference is the temperature difference between the vehicle's interior and exterior at the current moment; the second temperature difference is the temperature difference between the exterior of the vehicle and the inside of the windshield; the first preset threshold is greater than the second preset threshold; the target air conditioning mode is the mode of the vehicle's air conditioning before switching to the target anti-frost strategy; if the snowfall is within the second snowfall range, determining the target anti-frost strategy also includes: after a preset time, the air conditioning airflow direction is directed towards a third direction, and the blower rotates counterclockwise at the second gear; the third direction is used to indicate the top of the vehicle's cockpit; if the third temperature difference is less than the third preset threshold, the air conditioning airflow direction is directed towards the second direction, and the blower rotates clockwise at the third gear; if the fourth temperature difference is less than the fourth preset threshold, the air conditioning mode is the target air conditioning mode; the third temperature difference is the temperature difference between the vehicle's interior and exterior at the current moment, the fourth temperature difference is the temperature difference between the inside of the windshield and the exterior of the vehicle at the current moment, the third preset threshold is greater than the fourth preset threshold, and the speed at the third gear is less than the speed at the second gear.

Detailed Implementation
[0035] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.
[0036] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
[0037] Figure 1This is a schematic diagram of a scenario provided for an embodiment of this application.
[0038] For example, when driving in winter, users usually turn on the air conditioning in heating mode, which raises the temperature inside the vehicle. If the car is parked outdoors in cold weather (i.e., in an open or semi-open environment), the windshield is quite hot. The cold air outside the vehicle condenses into water when it meets the hot glass, and snowflakes melt on the hot glass. During this process, the temperature inside the vehicle begins to drop. When the temperature inside the vehicle drops to be close to the outside temperature, the water on the glass begins to frost. When the user drives the car again, they need to manually defrost it, resulting in a poor user experience.
[0039] To address the aforementioned technical problems, this application provides a vehicle control method, device, and vehicle. When the vehicle is in snowy weather, the method determines a target anti-frost strategy based on the amount of snowfall. This allows for the selection of a target anti-frost strategy that is suitable for the current environment of the vehicle, ensuring that the windshield can be prevented from frostling under such snowfall conditions. This avoids the need for users to manually defrost the windshield while using the vehicle, thereby improving the user experience.
[0040] Figure 2 This is a schematic flowchart illustrating a vehicle control method provided in an embodiment of this application. The execution subject of this method can be... Figure 1 The vehicle 100 contains computing devices with computing processing capabilities, such as the vehicle control unit (VCU).
[0041] For example, such as Figure 2 As shown, the method 200 includes S210 to S240, which are described in detail below.
[0042] S210 obtains weather information about the vehicle's environment when it detects a risk of frost forming on the vehicle's windshield.
[0043] Optionally, the weather information of the vehicle's environment can be obtained when the vehicle is locked and a risk of frost formation on the windshield is detected; or the weather information of the vehicle's environment can be obtained when the vehicle is running and a risk of frost formation on the windshield is detected. This application does not specifically limit the specific method of obtaining the weather information of the vehicle's environment.
[0044] One possible approach is to determine whether there is a risk of frost formation on the vehicle's windshield by measuring the temperature difference between the vehicle's interior and exterior, as well as the external humidity. Specifically, the vehicle's interior temperature is obtained using a temperature sensor located inside the vehicle, the exterior temperature is obtained using a temperature sensor located outside the vehicle, and the exterior humidity is obtained using a humidity sensor located outside the vehicle. The temperature difference between the interior and exterior temperatures is then determined. If the temperature difference exceeds a specific threshold and the external humidity exceeds a specific humidity threshold, then the vehicle is determined to be at risk of frost formation.
[0045] Another possible approach is to determine whether there is a risk of frost formation on the vehicle's windshield by measuring the temperature outside the vehicle, the temperature inside the vehicle, and the temperature inside the windshield. Specifically, a first temperature value inside the vehicle, a second temperature value outside the vehicle, and a third temperature value inside the windshield are obtained. If the first temperature value is greater than a first preset temperature value, the second temperature value is less than a second preset temperature value, and the third temperature value is greater than a third preset temperature value, then it is determined that there is a risk of frost formation on the vehicle's windshield.
[0046] Therefore, the process of S210 can be as follows: obtain a first temperature value inside the vehicle, a second temperature value outside the vehicle, and a third temperature value inside the windshield; if the first temperature value is greater than a first preset temperature value, the second temperature value is less than a second preset temperature value, and the third temperature value is greater than a third preset temperature value, obtain the weather information of the environment in which the vehicle is located.
[0047] The first preset temperature value > the third preset temperature value > the second preset temperature value. The first preset temperature value, the second preset temperature value, and the third preset temperature value can be set by those skilled in the art. For example, the first preset temperature value is 20℃, the second preset temperature value is -10℃, and the third preset temperature value is 15℃.
[0048] For example, when the temperature inside the vehicle is greater than 20°C, the temperature outside the vehicle is less than -10°C, and the temperature of the windshield is greater than 15°C, it is considered that there is a risk of frost forming on the windshield, and the weather information of the vehicle's environment is obtained. It should be understood that the first, second, and third preset temperature values can be adjusted based on experimental results, and this application embodiment does not specifically limit them.
[0049] In the above technical solution, since the temperature value of the inside of the windshield is between the temperature inside the vehicle and the temperature outside the vehicle, the windshield will not easily frost when the temperature inside the vehicle is high but the temperature value of the windshield is low (for example, when the user cools down the windshield before locking the car). Therefore, compared with determining the risk of windshield frost solely by the temperature values inside and outside the vehicle, this solution is more accurate in determining whether there is a risk of windshield frost by using the temperature values inside and outside the vehicle and the temperature value of the inside of the windshield together.
[0050] In some embodiments, to avoid affecting the normal driving of the vehicle, before obtaining the temperature values of the vehicle interior, vehicle exterior, and windshield interior, the following steps may be performed: determining whether the battery charge value of the vehicle is greater than a preset charge value.
[0051] The preset battery level can be set by those skilled in the art or by the user, for example, 90%. This application does not specifically limit this setting.
[0052] Furthermore, if the power value is greater than the preset power value, the first temperature value, the second temperature value, and the third temperature value are obtained.
[0053] In the above technical solution, since the battery is not durable in winter, if the battery level is less than the preset battery level, obtaining various temperature values to judge the risk of frost and implementing the target anti-frost strategy may cause the vehicle's battery to run out of power, affecting the normal driving of the vehicle. Therefore, when the battery level is greater than the preset battery level, obtaining the first temperature value, the second temperature value and the third temperature value can ensure that the normal driving of the vehicle will not be affected during the implementation of the target anti-frost strategy.
[0054] Optionally, weather forecast information for the vehicle's parking location can be obtained based on the vehicle's location information to obtain weather information for the vehicle's environment; weather information can also be obtained based on data from rain and snow sensors installed on the vehicle.
[0055] S220, based on weather information, determines whether the vehicle is in snowy weather.
[0056] For example, a rain and snow sensor contains a number of probes or tiny sensors that can detect the presence of rain and snow particles in the sky; the rain and snow sensor can not only detect whether it is snowing, but also monitor the amount of snowfall.
[0057] S230: If the vehicle is in a snowy weather environment, determine the target anti-frost strategy based on the amount of snowfall.
[0058] It should be understood that the rate at which frost forms on the windshield will vary depending on the amount of snowfall. Therefore, different anti-frost strategies are needed to prevent frost formation on the windshield.
[0059] The target anti-frost strategy is a strategy to prevent windshield frost in accordance with the amount of snowfall. This includes the degree to which the vehicle's windows are open and the mode of the vehicle's air conditioning. Frost on the windshield is prevented by controlling the opening of the windows and adjusting the mode of the vehicle's air conditioning.
[0060] The air conditioning modes include the air circulation mode, the direction of the airflow, the direction of the blower, and the speed of the blower. It should be understood that the direction of the airflow can be adjusted through the air outlet mode.
[0061] It should be understood that air conditioner circulation modes generally include internal circulation mode and external circulation mode, and air conditioner air outlet modes generally include face blowing mode, face and foot blowing mode, foot blowing mode, foot blowing defrost mode, and defrost mode, etc.
[0062] The direction of the blower's rotation determines the direction of airflow. For example, when the blower rotates clockwise, air flows from outside the vehicle to inside; when it rotates counterclockwise, air flows from inside the vehicle to outside. The blower's speed setting determines its rotational speed, which in turn determines the airflow volume of the air conditioner.
[0063] Furthermore, after determining the snowfall amount based on the rain and snow sensor, the implementation process of S230 can be as follows: if the snowfall amount is within the first preset snowfall amount range, the target anti-frost strategy is determined to include: the windows are opened at a preset opening degree, the air conditioning circulation mode is set to external circulation mode, the air conditioning airflow direction is directed towards the first direction and the second direction, and the air conditioning blower rotates clockwise in the first gear. If the snowfall is within the second preset snowfall range, the target anti-frost strategy is determined as follows: the windows are closed, the air conditioning is in external circulation mode, the air conditioning airflow is directed in the first direction, and the blower is rotating clockwise in the second gear.
[0064] The starting value of the second preset snowfall range is greater than the ending value of the first preset snowfall range. For example, the first preset snowfall range is (0mm / h, 5mm / h), and the second preset snowfall range is [5mm / h, +∞), or the first preset snowfall range is (0mm, 5mm / h], and the second preset snowfall range is (5mm / h, +∞). The first preset snowfall range and the second preset snowfall range can be set by those skilled in the art, and this application embodiment does not specifically limit them.
[0065] It should be understood that when the snowfall is within the first preset snowfall range, the current weather can be considered as light snow, and when the snowfall is within the second preset snowfall range, the current weather can be considered as heavy snow. The exterior temperature of vehicles during light snow is higher than that during heavy snow, and the exterior humidity of vehicles during light snow is lower than that during heavy snow.
[0066] The preset opening degree can be set within a preset safe range, for example, 10%. It should be understood that opening the windows allows hot air inside the vehicle to escape and lowers the interior temperature when the air conditioning is not turned on.
[0067] Optionally, the opening degree of the car window can also be dynamically adjusted according to the external environment of the vehicle. For example, by monitoring the external environment of the vehicle through a camera, if people are detected around the vehicle, the car window can be controlled to open at a preset opening degree. If no people are detected around the vehicle, the car window can be controlled to open at an opening degree greater than the preset opening degree.
[0068] It should be understood that if no pedestrians are detected around the vehicle, it means that the external environment of the vehicle is relatively safe. In order to achieve faster cooling inside the vehicle, when no pedestrians are detected, the windows can be opened to a greater extent (e.g., 20%) to achieve rapid cooling inside the vehicle.
[0069] It should be understood that in external circulation mode, when the blower rotates clockwise, it can draw cold air from outside the vehicle into the vehicle. The clockwise direction is the direction in which a clock moves.
[0070] The first direction indicates the bottom of the vehicle's cockpit; the second direction indicates the direction of the windshield; optionally, the direction of the air conditioning can be adjusted by adjusting the air conditioning's air outlet mode.
[0071] When the air outlet mode is set to foot defrost mode, the air conditioner directs the airflow towards the bottom of the vehicle's cabin (i.e., the driver's foot area) and the windshield; when the air outlet mode is set to foot defrost mode, the air conditioner directs the airflow towards the bottom of the vehicle's cabin.
[0072] The blower's second speed setting is higher than its first speed setting, meaning the blower outputs more air in the second speed setting compared to the first speed setting.
[0073] For example, when the snowfall is within a first preset snowfall range (i.e., light snow), the windows are opened to 10%, the air conditioning is in external circulation mode with the blower rotating clockwise at the first setting, and the airflow is in foot defrost mode. This draws cold air from outside the vehicle into the vehicle and blows it towards the bottom of the cabin, causing the warm air inside the vehicle to rise and dissipate through the open windows. Simultaneously, the cold air is blown towards the windshield, lowering its temperature and preventing condensation. Optionally, there can be one or more windows.
[0074] When the snowfall is within the second preset snowfall range (i.e., during heavy snow), the windows are closed to prevent snow from entering the vehicle and damaging the interior components. The air conditioning is set to external circulation mode and the blower is rotated clockwise at the second setting. The airflow mode is set to foot blowing mode, which blows more cold air towards the bottom of the vehicle's cabin.
[0075] In the above technical solution, when the snowfall is within the first preset snowfall range (e.g., light snow), the air conditioning circulation mode is external circulation mode and the blower is rotated clockwise, which can blow cold air from outside the vehicle into the vehicle; the air outlet mode is foot defrosting mode, which blows cold air towards the bottom of the vehicle's cabin, allowing the hot air inside the vehicle to rise and be exhausted through the open windows, thus achieving rapid cooling of the vehicle's interior; by blowing cold air towards the windshield, the windshield can be cooled down quickly, preventing frost from forming on the windshield. In summary, this anti-frost strategy can prevent windshield frost in light snow.
[0076] When the snowfall is within the second preset snowfall range (e.g., heavy snow), the temperature outside the vehicle is lower and the humidity is higher than in light snow. Therefore, the blower is set to the second setting to blow more cold air into the vehicle, which cools the interior of the vehicle quickly. Under this type of snowfall, keeping the windows closed can prevent rain or snow from entering the vehicle and damaging the interior components.
[0077] In addition, the above solution cools the vehicle interior by using the air conditioner's external circulation mode and opening the windows, which is more energy-efficient than using the cooling mode to cool the vehicle interior.
[0078] Optionally, if the snowfall amount is within the first snowfall amount range, the target anti-frost strategy may further include: if the first temperature difference is less than the first preset threshold and the second temperature difference is less than the second preset threshold, the windows are closed, and the air conditioning mode is switched to the target air conditioning mode.
[0079] The first temperature difference is the temperature difference between the inside and outside of the vehicle at the current moment; the second temperature difference is the temperature difference between the outside of the vehicle and the inside of the windshield. It should be understood that when the outside temperature of the vehicle is lower than the inside temperature of the vehicle, and the temperature difference is greater than a certain value (e.g., 20°C), the windshield of the vehicle is prone to frost formation.
[0080] The first preset threshold is greater than the second preset threshold. The first and second preset thresholds can be set by those skilled in the art. For example, the first preset threshold is 15°C and the second preset threshold is 10°C. This application embodiment does not specifically limit this.
[0081] The target air conditioning mode is the mode of the air conditioning in the vehicle before switching to the target anti-frost strategy. For example, if the air conditioning was in heating mode and turned off before the vehicle switched to the target anti-frost strategy, then after switching to the target air conditioning mode, the air conditioning will be in heating mode and turned off.
[0082] For example, if the first temperature difference is less than the first preset threshold and the second temperature difference is less than the second preset threshold, it means that the windshield is not easy to frost at this time, and there is no need to cool down the vehicle interior and the windshield. Therefore, in order to protect the vehicle's safety and save power, the windows can be kept closed, and the air conditioning mode can be switched to the air conditioning mode last set by the user before the target anti-frost strategy was implemented.
[0083] Optionally, if the snowfall is within the second preset snowfall range, the target anti-frost strategy may further include: after a preset time, the air conditioner directs the airflow to a third direction and the blower rotates counterclockwise at the second setting; if the third temperature difference is less than the third preset threshold, the air conditioner directs the airflow to the second direction and the blower rotates clockwise at the third setting; if the fourth temperature difference is less than the fourth preset threshold, the air conditioner is set to the target air conditioner mode.
[0084] Optionally, the preset duration can be a fixed duration, such as 20 seconds; it can also be determined based on the temperature difference between the inside and outside of the vehicle. The greater the temperature difference, the longer the preset duration; for example, when the temperature difference is 20 degrees or higher, the preset duration is 50 seconds, and when the temperature difference is less than 20 degrees, the preset duration is 20 seconds. This application does not impose specific limitations on this.
[0085] The second direction is used to indicate the direction of the windshield, and the third direction is used to indicate the top of the vehicle's cockpit; optionally, the air conditioning's air outlet mode can be adjusted to defrost mode so that the air conditioning airflow is directed towards the direction of the windshield; the air conditioning's air outlet mode can be adjusted to face blowing mode so that the air conditioning airflow is directed towards the top of the cockpit.
[0086] In the blowing mode, when the blower rotates counterclockwise, it can blow the air from the top of the vehicle to the outside of the vehicle.
[0087] The third temperature difference value is the temperature difference between the inside and outside of the vehicle at the current moment, and the fourth temperature value is the temperature difference between the inside of the windshield and the outside of the vehicle at the current moment; the third and fourth preset thresholds can be set by those skilled in the art, for example, the third preset threshold is 15℃ and the fourth preset threshold is 10℃; the speed of the third gear is lower than that of the second gear.
[0088] For example, in the foot-blowing mode described above, since the car windows are closed, the hot air inside the car rises but is not expelled. In order to speed up the cooling of the car, the air conditioning is set to face-blowing mode and the blower is reversed to expel the rising hot air outside the car.
[0089] Furthermore, when the third temperature difference is less than the third preset threshold, it indicates that the temperature inside the vehicle has dropped and is mostly cold air. At this time, the air outlet mode is the defrost mode, and the blower rotates clockwise to blow the cold air from outside the vehicle toward the windshield, causing the windshield to cool down quickly. When the fourth temperature difference is less than the fourth preset threshold, it indicates that the windshield is not easy to frost at this time. The target anti-frost strategy is stopped by switching the air conditioning mode to the target air conditioning mode.
[0090] In the above technical solution, during light snow, when the first temperature difference is less than the first preset threshold and the second temperature difference is less than the second preset threshold, it indicates that the temperature inside the vehicle and the temperature of the windshield have reached a level where frost is unlikely to form. At this time, closing the windows can improve safety. Switching the air conditioning mode to the last air conditioning mode set by the user before implementing the target anti-frost strategy ensures that when the owner starts the vehicle again, the air conditioning will work according to the mode previously set by the owner, avoiding the air conditioning operating in the defrosting mode when the vehicle is turned on, which would cause the interior temperature of the vehicle to be too low and affect the user experience.
[0091] In heavy snow, after a preset time, adjust the airflow mode to face-blowing mode and control the blower to rotate counterclockwise. Since the hot air inside the vehicle rises and the windows are not open, it cannot escape. Therefore, rotating the blower counterclockwise can expel the rising hot air from the vehicle, allowing the interior temperature to drop quickly. When the temperature difference between the interior and exterior of the vehicle is less than the third preset threshold, it means that most of the air inside the vehicle is already cold, making it difficult to heat the windshield. At this point, adjust the airflow mode to defrost mode to quickly cool the windshield and prevent frost from forming. Furthermore, when most of the air inside the vehicle is already cold, running the blower at a lower setting (less than the second setting) will quickly cool the windshield, saving energy while preventing frost formation.
[0092] It should be understood that snowfall weather includes not only heavy snow and light snow, but also rain mixed with snow. In rain mixed with snow weather, the humidity is higher and the temperature is lower than in light snow weather, and the windshield will frost up faster. Therefore, the embodiments of this application provide the same anti-frost strategy for rain mixed with snow weather as for heavy snow weather.
[0093] In other words, the implementation process of S230 can be as follows: if snowfall and rainfall are detected, the target anti-frost strategy is determined to include: the windows are closed, the air conditioning is in external circulation mode, the air conditioning airflow is directed in the first direction, and the air conditioning blower is rotating clockwise in the second gear.
[0094] Similarly, if snowfall and rainfall are detected, the target anti-frost strategy also includes: after a preset time, the air conditioner's airflow direction is turned towards the third direction, and the blower rotates counterclockwise at the second setting; if the third temperature difference is less than the third preset threshold, the air conditioner's airflow direction is turned towards the second direction, and the blower rotates clockwise at the third setting; if the fourth temperature difference is less than the fourth preset threshold, the air conditioner mode is the target air conditioner mode.
[0095] It should be understood that since snowfall and rainfall can only be detected by rain and snow sensors when they reach a certain level, the detection of snowfall and rainfall can be interpreted as the current weather being rain and snow.
[0096] Since the anti-frost strategy for rainy and snowy weather is the same as that for heavy snow weather, it will not be repeated here.
[0097] S250 controls the vehicle to execute the target anti-frost strategy.
[0098] For example, after determining the target anti-frost strategy in S240, the vehicle is controlled to open or close the windows and turn the air conditioning on or off based on the target anti-frost strategy.
[0099] In the above technical solution, when it is determined that there is a risk of frost forming on the windshield, the weather information of the vehicle's environment is obtained. If the weather information indicates snowfall, a target anti-frost strategy is determined based on the amount of snowfall and executed to prevent windshield frost formation. Since vehicle windshields are more prone to frost formation in snowfall, and the rate of frost formation varies with different amounts of snowfall, determining the target anti-frost strategy based on the amount of snowfall in the vehicle's environment can select the most suitable target anti-frost strategy, ensuring that windshield frost formation can be prevented under snowfall conditions.
[0100] Figure 3 This is a schematic flowchart illustrating a vehicle control method under light snow conditions, provided as an embodiment of this application.
[0101] For example, such as Figure 3 As shown, the method 300 includes steps S310 to S340, which are described in detail below.
[0102] S310 obtains weather information about the vehicle's environment when it detects a risk of frost forming on the vehicle's windshield.
[0103] For example, the implementation of S310 can be found in the relevant description of the S210 process in the above example embodiment, and will not be repeated here.
[0104] S320: Based on weather information, determine whether the weather in the vehicle's environment is light snow. If so, execute S330.
[0105] For example, the system determines whether the vehicle is in light snow based on the amount of snowfall detected by the rain and snow sensor. If so, it controls the windows to open to a preset degree, turns on the air conditioner in external circulation mode and foot defrost mode, and controls the blower to rotate clockwise in the first position.
[0106] S330 controls the windows to open to a preset degree, activates the air conditioning's external circulation mode and foot defrost mode, and controls the blower to rotate clockwise in the first position.
[0107] For example, the implementation of S330 can be found in the relevant description of the S230 process in the above example embodiment, and will not be repeated here.
[0108] S340: If the temperature difference between the inside and outside of the vehicle is less than the first preset threshold and the temperature difference between the inside of the windshield and the outside of the vehicle is less than the second preset threshold, control the windows to close and switch the air conditioning mode to the user's initial air conditioning mode.
[0109] For example, if the temperature difference between the inside and outside of the vehicle is less than a first preset threshold and the temperature difference between the inside of the windshield and the outside of the vehicle is less than a second preset threshold, it can be assumed that the windshield is not prone to frost. To ensure vehicle safety, the windows are closed, and the air conditioning mode is switched to the user's initial setting. For example, the air conditioning is in heating mode before the user locks the car. When it is determined that the windshield is not prone to frost, the air conditioning mode is switched to heating mode and then the air conditioning is turned off.
[0110] Figure 4 This is a schematic flowchart illustrating a vehicle control method under heavy snow or rain and snow weather, provided as an embodiment of this application.
[0111] For example, such as Figure 4As shown, the method 400 includes steps S410 to S460, which are described in detail below.
[0112] S410 obtains weather information about the vehicle's environment when it detects a risk of frost forming on the vehicle's windshield.
[0113] For example, the implementation of S410 can be found in the relevant description of the S210 process in the above example embodiment, and will not be repeated here.
[0114] S420: Based on weather information, determine whether the vehicle is in heavy snow or rain and snow. If so, execute S430.
[0115] For example, the system determines whether the vehicle is in heavy snow or rain and snow based on the amount of snowfall or rainfall detected by the rain and snow sensor. If so, it controls the windows to be closed, turns on the air conditioner in external circulation mode and foot blowing mode, and controls the blower to rotate clockwise in the second gear.
[0116] S430: With the windows closed, turn on the air conditioning in external circulation mode and foot blowing mode, and control the blower to rotate clockwise at the second setting.
[0117] For example, the implementation of S430 can be found in the relevant description of the S230 process in the above example embodiment, and will not be repeated here.
[0118] S440 switches the foot blowing mode to the face blowing mode after a preset time, and controls the blower to rotate counterclockwise in the second gear.
[0119] For example, after a preset duration (e.g., 20 seconds), the external circulation mode remains unchanged, the foot blowing mode is switched to the face blowing mode, and the blower is controlled to reverse at the second gear.
[0120] S450: If the temperature difference between the inside and outside of the vehicle is less than the third preset threshold, switch the blowing mode to the defrosting mode and control the blower to rotate clockwise at the third position.
[0121] For example, when the temperature difference between the inside and outside of the vehicle is less than the third preset threshold, the external circulation mode remains unchanged, the blowing mode is switched to the defrosting mode, and the blower is controlled to rotate forward at the third gear.
[0122] S460: If the temperature difference between the inside of the windshield and the outside of the vehicle is less than the fourth preset threshold, the air conditioning mode will be switched to the user's initial air conditioning mode.
[0123] For example, the implementation of S460 can be found in the relevant description of the S230 process in the above example embodiment, and will not be repeated here.
[0124] The above embodiments describe the target anti-frosting strategy for vehicles in snowy weather. The following describes the target anti-frosting strategy for vehicles in non-snowy weather.
[0125] In some embodiments, if the vehicle is in an environment where it is not snowing, the windows and sunroof are opened to a preset opening degree, the air conditioning circulation mode is adjusted to external circulation mode, the air conditioning airflow direction is directed to the first direction and the second direction, and the air conditioning blower rotates clockwise at the fourth position.
[0126] Optionally, both the windows and the sunroof can be controlled to open at a preset opening degree; alternatively, the windows can be controlled to open at a preset opening degree, and the sunroof can open at an opening degree greater than the preset opening degree.
[0127] It should be understood that the sunroof is located on the top of the vehicle and is safer than the windows. Therefore, in order to achieve rapid cooling of the vehicle interior, the sunroof can be opened wider than the windows.
[0128] For example, the car windows are opened to 10% and the sunroof is opened to 20%.
[0129] It should be understood that, since the humidity is lower and the temperature is higher outside the vehicle in non-snowy weather compared to snowy weather, the fourth gear can be lower than the first gear.
[0130] It should be understood that since the vehicle is in an environment where it is not snowing, the sunroof and windows can be opened simultaneously, with the sunroof opening wider than the windows, allowing the hot air inside the vehicle to dissipate more quickly and cool the interior. At the same time, the air venting mode is set to foot defrost mode, which allows the hot air inside the vehicle to rise and dissipate through the windows and sunroof, reducing the interior temperature of the vehicle and the temperature of the windshield.
[0131] Figure 5 This is a schematic flowchart illustrating another vehicle control method provided in an embodiment of this application.
[0132] For example, such as Figure 5 As shown, the method 500 includes S501 to S517, which are described in detail below.
[0133] S501: If a vehicle locking command is received, determine whether the vehicle's battery charge is greater than the preset charge value. If so, execute S502.
[0134] The preset battery level can be 90%, but this application does not specifically limit this value.
[0135] For example, after exiting the vehicle, a user can issue a vehicle locking command via a mobile app. This command is transmitted to the T-Box (Telematics Box) through the TSP (Telematics Service Provider) platform. After the T-Box verifies the user's identity, it activates the vehicle network and sends the locking command to the controller. If the battery level is greater than 90% upon receiving the locking command, the system acquires the first temperature value inside the vehicle, the second temperature value outside the vehicle, and the third temperature value inside the windshield. If the battery level is less than or equal to 90%, no action is taken.
[0136] S502, acquires a first temperature value inside the vehicle, a second temperature value outside the vehicle, and a third temperature value inside the windshield.
[0137] For example, temperature values inside the vehicle, outside the vehicle, and inside the windshield are measured by temperature sensors installed inside and outside the vehicle, and a first temperature value, a second temperature value, and a third temperature value are obtained by acquiring data from the temperature sensors.
[0138] S503: Determine whether there is a risk of frost formation on the windshield based on the first temperature value, the second temperature value, and the third temperature value. If so, proceed to S504.
[0139] For example, if the first temperature value is greater than the first preset temperature value (e.g., 20°C), the second temperature value is less than the second preset temperature value (e.g., -10°C), and the third temperature value is greater than the third preset temperature value (e.g., 15°C), it is determined that there is a risk of frost forming on the windshield.
[0140] S504, determine whether the vehicle is in snowy weather. If yes, proceed to S505; otherwise, proceed to S514.
[0141] For example, the implementation of S504 can be found in the relevant description of the S230 process in the above example embodiment, and will not be repeated here.
[0142] S505, determine whether the snowfall type is heavy snow or rain and snow. If not, proceed to S506; if so, proceed to S510.
[0143] For example, the rain and snow sensor can determine whether the snowfall type is heavy snow or rain and snow. If not, the window is opened to a preset opening degree; the air conditioner's external circulation mode and foot defrost mode are turned on and the blower is turned on at the first speed. If so, the air conditioner's external circulation mode and foot defrost mode are turned on and the blower is turned on at the second speed.
[0144] S506 controls the windows to open at a preset angle; controls the air conditioning to activate the external circulation mode and foot defrost mode, with the blower rotating at the first speed.
[0145] The preset opening degree can be 10%, but this application embodiment does not specifically limit it.
[0146] It should be understood that in external circulation mode, the air conditioner's vents are open, allowing outside air to enter the vehicle and inside air to flow outside.
[0147] In foot defrost mode, the air conditioning vents are directed towards the bottom of the vehicle's cabin and the direction of the windshield.
[0148] When the blower is rotating clockwise in the first gear, the external circulation mode is activated, so the blower can blow cold air from outside the vehicle into the vehicle. In the foot defrost mode, the cold air is blown towards the bottom of the vehicle's cabin and the windshield.
[0149] S507, acquire a first temperature difference between the inside and outside of the vehicle and a second temperature difference between the inside of the windshield and the outside of the vehicle.
[0150] For example, a first temperature difference between the inside and outside of the vehicle is obtained by acquiring the temperature values inside and outside the vehicle; a second temperature difference is obtained by acquiring the temperature value inside the windshield and the temperature value outside the vehicle.
[0151] S508, determine whether the first temperature difference is less than the first preset threshold and the second temperature difference is less than the second preset threshold. If so, execute S509.
[0152] The first preset threshold is greater than the second preset threshold. For example, the first preset threshold can be 15℃ and the second preset threshold can be 10℃.
[0153] S509, controls the windows to close, switches the air conditioning mode to the mode used when the vehicle is locked, and then controls the air conditioning to turn off.
[0154] For example, while controlling the windows to close, the air conditioning mode can be switched from the current air conditioning mode to the air conditioning mode when the vehicle is locked. For instance, if the air conditioning mode when the vehicle is locked is recirculation mode and heating mode, then the current air conditioning mode can be switched to recirculation mode and heating mode before the air conditioning is turned off.
[0155] S510 controls the air conditioner to activate its external circulation mode and foot blowing mode, and sets the blower to the second speed setting.
[0156] It should be understood that in foot-blowing mode, the air conditioning vents towards the bottom of the vehicle's cabin, and the blower outputs the air volume corresponding to the second setting.
[0157] S511, after the target duration, control the foot blowing mode to turn off, the face blowing mode to turn on, and the blower to reverse at the second gear.
[0158] The target duration can be determined based on the temperature difference between the outside and inside of the vehicle. For details, please refer to the S420 process; it will not be repeated here.
[0159] It should be understood that in the face-blowing mode, the air conditioner directs the airflow towards the top of the vehicle's cabin. When the blower is in the second gear and rotating counterclockwise, since the external circulation mode and face-blowing mode are activated, the reverse rotation of the blower can blow the hot air from the top of the vehicle out of the vehicle.
[0160] S512, if the temperature difference between the inside and outside of the vehicle is less than the third preset threshold, the blowing mode is turned off, the defrosting mode is turned on, and the blower rotates in the third gear.
[0161] The third preset threshold can be 15°C, but this application embodiment does not specifically limit it.
[0162] It should be understood that in defrost mode, the air conditioner directs the airflow towards the windshield, and the blower, rotating in the third gear, can blow cold air from outside the vehicle toward the windshield, causing the windshield temperature to drop.
[0163] S513 If the temperature difference between the inside of the windshield and the outside of the vehicle is less than the fourth preset threshold, the air conditioning mode is switched to the air conditioning mode when the vehicle is locked and then the air conditioning is turned off.
[0164] For example, the implementation of S513 can be found in the relevant description of the S509 process in the above example embodiment, and will not be repeated here.
[0165] S514 controls the windows to open to the first preset opening degree and the sunroof to open to the second preset opening degree; controls the air conditioning to activate the external circulation mode and the foot defrost mode, and controls the blower to rotate in the fourth gear.
[0166] The second preset opening is greater than the first preset opening. The first and second preset openings can be set by those skilled in the art. For example, the first preset opening is 10% and the second preset opening is 20%. No specific limitation is made here.
[0167] S515, obtain the fifth temperature difference between the inside and outside of the vehicle and the sixth temperature difference between the inside of the windshield and the outside of the vehicle.
[0168] For example, the implementation of S515 can be found in the relevant description of the S507 process in the above example embodiment, and will not be repeated here.
[0169] S516, determine whether the fifth temperature difference is less than the fifth preset threshold and the sixth temperature difference is less than the sixth preset threshold. If so, execute S517.
[0170] The fifth preset threshold is greater than the sixth preset threshold. For example, the fifth preset threshold can be 20℃ and the sixth preset threshold can be 15℃.
[0171] S517 controls the closing of windows and sunroof, and switches the air conditioning mode to the mode used when the vehicle is locked before turning off the air conditioning.
[0172] For example, the implementation of S517 can be found in the relevant description of the S340 process in the above example embodiment, and will not be repeated here.
[0173] Figure 6 This is a schematic diagram of the structure of a vehicle control device provided in an embodiment of this application.
[0174] For example, such as Figure 6 As shown, the device 600 includes: The first acquisition module 610 is used to acquire weather information of the vehicle's environment when a risk of frost forming on the vehicle's windshield is detected. The first determining module 620 is used to determine whether the vehicle's environment is snowy based on weather information; The second determining module 630 is used to determine a target anti-frost strategy based on the amount of snowfall if the vehicle is in a snowy weather environment.
