Detailed Implementation

[0016] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Reference Figure 1 This document illustrates a flowchart of an embodiment of a vehicle-mounted humidity system control method according to this application. The vehicle-mounted humidity system includes an evaporator, an air heating device, and an air humidifier arranged sequentially along the airflow direction. In this embodiment, the vehicle-mounted humidity system can be installed separately in the vehicle's air conditioning system. This system includes an evaporator, an air heating device, and an air humidifier arranged sequentially along the airflow direction. That is, when air is drawn into the vehicle-mounted humidity system from inside or outside the vehicle, it first passes through the evaporator, then flows to the air heating device, then to the air humidifier, and finally is delivered to the user. When activated, the air heating device and the air humidifier process the flowing air accordingly.

[0018] The vehicle-mounted humidity system control method may specifically include the following steps: Step 101: In response to the humidity control command, obtain the real-time humidity inside the vehicle and the target humidity corresponding to the humidity control command; When a user needs to adjust the humidity inside the vehicle, they can issue a humidity control command through interactive components such as the central control screen or control knobs. This humidity control command indicates a need for humidity adjustment. In response to the humidity control command, the system can obtain the real-time humidity inside the vehicle and the target humidity corresponding to the command. The real-time humidity inside the vehicle is the current humidity value of the air in the cabin. The target humidity is the humidity value that the user wants to achieve as specified in the humidity control command. For example, if a user sets the humidity to A (range: 0%–100%, accuracy: 1%) via the central control screen, a humidity control command can be generated. The target humidity is then A.

[0019] Step 102: Determine the humidity difference between the real-time humidity inside the vehicle and the target humidity; It can calculate the difference between the real-time humidity inside the vehicle and the target humidity, and determine it as the humidity difference.

[0020] Step 103: When the real-time humidity inside the vehicle is less than the target humidity, control the air humidification device to humidify the air based on the humidity difference. If the real-time humidity inside the vehicle is lower than the target humidity, meaning the current air humidity inside the vehicle is low, it is necessary to increase the air humidity. The humidity difference can be used as a control variable to activate the air humidifier. Air can then flow through the humidifier, which humidifies the air, and the humidified air is then delivered into the vehicle cabin.

[0021] Step 104: If the real-time humidity inside the vehicle is greater than the target humidity, control the air heating device to dehumidify the air based on the humidity difference and / or control the evaporator to reach the target temperature to dehumidify the air.

[0022] If the real-time humidity inside the vehicle exceeds the target humidity, meaning the current humidity level is high, it's necessary to reduce it. This can be achieved by using the humidity difference as a control variable to activate the air heater, allowing water vapor to be released as air flows through the evaporator, thus lowering the humidity. Alternatively, the target temperature of the evaporator can be controlled based on the humidity difference, heating the air as it passes through the air heater to further dry it, thereby dehumidifying the air. Finally, the dehumidified air is delivered into the vehicle cabin.

[0023] This application embodiment obtains the real-time humidity inside the vehicle and the target humidity corresponding to the humidity control command in response to a humidity control command; determines the humidity difference between the real-time humidity inside the vehicle and the target humidity; when the real-time humidity inside the vehicle is less than the target humidity, controls an air humidifier to humidify the air based on the humidity difference; when the real-time humidity inside the vehicle is greater than the target humidity, controls an air heater to dehumidify the air and / or controls the evaporator to reach the target temperature to dehumidify the air based on the humidity difference. By setting up an in-vehicle humidity system, by detecting the difference between the real-time humidity inside the vehicle and the target humidity, the system controls the air humidifier to humidify the air, controls the air heater to dehumidify the air, and / or controls the evaporator to reach the target temperature to dehumidify the air; it can independently control the humidity of the air conditioner, and the humidity control does not depend on the temperature control, which can achieve precise control of the humidity inside the vehicle and improve control accuracy; and since the humidity can be directly controlled, it avoids indirect control through temperature, which can improve control efficiency.

[0024] Reference Figure 2 This diagram illustrates a flowchart of another embodiment of the vehicle-mounted humidity system control method of this application. The vehicle-mounted humidity system includes an internal / external circulation switching device, an evaporator, an air heating device, and an air humidification device arranged sequentially along the airflow direction. See also... Figure 3 The vehicle-mounted humidity system may include an internal / external circulation switching device 1, an evaporator 2, an air heating device 3, and an air humidification device 4. The internal / external circulation switching device 1 is located at the inlet of the vehicle-mounted humidity system. It switches the source of fresh air entering the system, allowing for switching between internal and external circulation airflow as the fresh air for humidity control. The internal / external circulation switching device 1 may include an internal circulation inlet 11, an external circulation inlet 12, and a circulation damper 13. The internal circulation inlet 11 receives internal circulation airflow. The external circulation inlet 12 receives external circulation airflow. The circulation damper 13 is located on the same side of the internal circulation inlet 11 and the external circulation inlet 12. The circulation damper 13 can move between the internal circulation inlet 11 and the external circulation inlet 12. Figure 3As shown, the air intake 13 can slide between the internal circulation intake 11 and the external circulation intake 12. When the circulation damper 13 slides onto the internal circulation intake 11, it closes the internal circulation intake 11, and the fresh air source for the vehicle humidity control system is the external circulation airflow. When the circulation damper 13 slides onto the external circulation intake 12, it closes the external circulation intake 12, and the fresh air source for the vehicle humidity control system is the internal circulation airflow. The evaporator 2 is located on the air outlet side of the internal / external circulation switching device 1 and processes the air output by the internal / external circulation switching device 1. The evaporator 2 can be the evaporator of the air conditioning system. The air heating device 3 is located on the air outlet side of the evaporator 2. The air heating device 3 can heat the air, making the air dry and reducing the relative humidity. The air heating device 3 can include a heater 31 and a heating damper 32. The heating damper 32 is located on the air inlet side of the heater 31. When the heating damper 32 is closed, it blocks the heater 31, and the air will not flow through the heater 31, thus not heating and dehumidifying the air. When the heating damper 32 is open, it does not obstruct the heater 31, allowing air to flow through and be heated and dehumidified. An air humidification device 4 is located on the air outlet side of the air heating device 3, humidifying the air. The air humidification device 4 may include a humidifier 41 and a humidification damper 42. The humidification damper 42 is located on the air inlet side of the humidifier 41. When the humidification damper 42 is closed, it obstructs the humidifier 41, preventing air from flowing through it and thus humidifying the air. When the humidification damper 42 is open, it does not obstruct the humidifier 41, allowing air to flow through and be humidified. Finally, the air can be delivered to the vehicle cabin through different air outlet channels. For example, air can be delivered to the user's body through an air outlet channel facing the user's feet. Air can be delivered to the user's feet through an air outlet channel facing the windshield. Air can be delivered to the windshield through an air outlet channel facing the windshield. In addition, it can be like Figure 3 As shown, multiple humidity sensors are installed on the vehicle's humidity control system to detect the air humidity at different locations. Four humidity sensors can be installed in the vehicle, and these sensors can be integrated with the vehicle's temperature sensors. Humidity sensor RH1 is located in the face vent duct to detect the humidity of the air blowing towards the user's body; humidity sensor RH2 is located in the foot vent duct to detect the humidity of the air blowing towards the user's feet; humidity sensor RH3 is located on the dashboard to detect the humidity of the air inside the vehicle's cabin, i.e., the humidity of the recirculated airflow; and humidity sensor RH4 is located on the air conditioning intake to detect the humidity of the external recirculated airflow.

[0025] The vehicle-mounted humidity system control method may specifically include the following steps: Step 201: In response to the humidity control command, obtain the real-time humidity inside the vehicle and the target humidity corresponding to the humidity control command; When users need to adjust the humidity inside the vehicle cabin, they can issue a humidity control command by operating the in-vehicle interactive components or through a third-party operating device. The system can respond to the humidity control command, obtain the real-time humidity inside the vehicle, and the target humidity corresponding to the command. For example, it can obtain... Figure 3 The humidity value collected by the humidity sensor RH3 in the vehicle is used as the real-time humidity inside the vehicle.

[0026] Step 202: Determine the humidity difference between the real-time humidity inside the vehicle and the target humidity; The difference between the real-time humidity inside the vehicle and the target humidity can be determined, and the absolute value of this difference can be used as the humidity difference value.

[0027] Step 203: Obtain the inner and outer loop patterns; The internal / external air circulation mode can also be determined by detecting the state of the internal / external circulation knob, setting operation events, and air inlet position. Internal / external circulation modes can include manual and automatic modes. Manual circulation mode is the air circulation mode where the user manually switches between internal and external circulation. Automatic circulation mode is the air circulation mode where the vehicle controller or air conditioning controller automatically switches between internal and external circulation based on environmental conditions.

[0028] Step 204: In the automatic circulation mode of the internal and external circulation modes, obtain the humidity of the internal circulation airflow and the humidity of the external circulation airflow. In automatic circulation mode, both internal and external airflow can be controlled as a source of fresh air to further enhance humidity control effectiveness and improve accuracy. The humidity of both the internal and external airflow can be obtained. The internal airflow humidity refers to the humidity of the air within the internal airflow. The external airflow humidity refers to the humidity of the air within the external airflow. For example, the humidity of... Figure 3 The humidity value collected by the humidity sensor RH3 is used as the humidity of the internal recirculation airflow. It can obtain values ​​such as... Figure 3 The humidity value collected by the humidity sensor RH4 in the system is used as the humidity of the external circulating airflow.

[0029] Step 205: Based on the humidity of the internal circulating airflow and the humidity of the external circulating airflow, control the internal and external circulation switching device; By comparing the humidity of the internal and external circulating air, the required circulating airflow is determined as the source of fresh air, and the internal and external circulation switching device is controlled to introduce the corresponding circulating airflow.

[0030] In an optional embodiment of this application, the step of controlling the internal and external circulation switching device based on the humidity of the internal circulation airflow and the humidity of the external circulation airflow includes: Sub-step S2051: Based on the humidity of the internal circulation airflow and the humidity of the external circulation airflow, determine the target air intake from the internal circulation air intake and the external circulation air intake; The humidity of the internal and external circulating air can be compared to determine the circulating air that meets the target humidity setting requirements. The corresponding air intake end of the circulating air can then be selected, that is, one of the internal and external air intake ends can be selected as the target air intake end.

[0031] In one example, the step of determining the target air intake from the internal and external air intakes based on the internal airflow humidity and the external airflow humidity includes: when the real-time humidity inside the vehicle is less than the target humidity, determining the target airflow humidity based on the larger of the internal and external airflow humidity; and determining the target air intake from the internal and external air intakes based on the target airflow humidity.

[0032] When the real-time humidity inside the vehicle is lower than the target humidity, air with higher humidity can be introduced as the fresh air source to humidify the air. The humidity of the recirculated airflow and the external recirculated airflow can be compared, and the higher humidity can be selected as the target airflow humidity. The airflow corresponding to this target humidity is then designated as the target recirculated airflow. The intake end corresponding to this target recirculated airflow is then determined as the target intake end, either the internal or external recirculated air intake end. For example, if the internal recirculated airflow humidity is higher, the internal recirculated air intake end can be designated as the target intake end. If the external recirculated airflow humidity is higher, the external recirculated air intake end can be designated as the target intake end. By introducing fresh air with corresponding higher humidity to directly dehumidify the air, the operating energy consumption of each device can be reduced, thereby reducing the overall energy consumption of the vehicle's humidity control system.

[0033] In another example, the step of determining the target air intake from the internal air intake and the external air intake based on the internal airflow humidity and the external airflow humidity includes: when the real-time humidity inside the vehicle is greater than the target humidity, using the smaller of the internal airflow humidity and the external airflow humidity as the target airflow humidity; and determining the target air intake from the internal air intake and the external air intake based on the target airflow humidity.

[0034] When the real-time humidity inside the vehicle exceeds the target humidity, dehumidification is necessary. Therefore, air with lower humidity can be introduced as the fresh air source. The humidity levels of the recirculated and external airflows can be compared, and the lower humidity level is selected as the target airflow humidity. The airflow corresponding to this target humidity is then designated as the target recirculated airflow. The intake end corresponding to this target recirculated airflow is then determined as the target intake end, either the recirculated or external airflow intake. For example, if the recirculated airflow humidity is lower, the recirculated intake end can be designated as the target intake end. If the external airflow humidity is lower, the external airflow intake end can be designated as the target intake end. By directly introducing fresh air with lower humidity to dehumidify the air, the operating energy consumption of individual devices can be reduced, thereby lowering the overall energy consumption of the vehicle's humidity control system.

[0035] Sub-step S2052: Control the circulating damper to open the target air intake end.

[0036] It can control the recirculation damper to open the target air intake, allowing air to be introduced as a fresh air source. For example, see... Figure 3 When the target air intake is the external circulation intake, the recirculation damper can be controlled to slide to the internal circulation intake, closing the internal circulation intake and opening the external circulation intake. When the target air intake is the internal circulation intake, the recirculation damper can be controlled to slide to the external circulation intake, closing the external circulation intake and opening the internal circulation intake. By introducing fresh air of the appropriate humidity to directly adjust the air humidity, the operating energy consumption of each device can be reduced, thereby reducing the overall energy consumption of the vehicle's humidity system.

[0037] Step 206: If the real-time humidity inside the vehicle is less than the target humidity, control the air humidification device to humidify the air based on the humidity difference. When the real-time humidity inside the vehicle is lower than the target humidity, the air in the vehicle cabin can be humidified. The humidification device can be activated based on the humidity difference, and air can flow through it. The humidification device then humidifies the air.

[0038] In an optional embodiment of this application, the step of controlling the air humidification device to humidify the air based on the humidity difference when the real-time humidity inside the vehicle is less than the target humidity includes: Sub-step S2061: When the real-time humidity inside the vehicle is less than the target humidity, determine the opening degree of the first damper corresponding to the humidity difference. If the real-time humidity inside the vehicle is lower than the specified humidity level, a humidifier needs to be turned on for humidification. The humidity difference can be mapped to the corresponding humidification damper opening, which is then defined as the first damper opening. The first damper opening represents the target opening of the humidification damper. The humidity difference and the humidification damper opening can be pre-calibrated through simulation, experimentation, etc. This application does not limit the specific mapping relationship.

[0039] Sub-step S2062: Control the humidifier to start and the humidification damper to reach the first damper opening degree.

[0040] It can control the humidifier's startup, such as turning on the humidifier's switch to activate it. It also controls the humidification damper to reach its first opening degree, allowing air to flow through the humidifier for humidification. By directly humidifying the air through the humidifier, precision and efficiency can be controlled.

[0041] Step 207: If the real-time humidity inside the vehicle is greater than the target humidity, control the air heating device to dehumidify the air based on the humidity difference and / or control the evaporator to reach the target temperature to dehumidify the air.

[0042] When the real-time humidity inside the vehicle exceeds the target humidity, the air in the vehicle cabin can be dehumidified. The target temperature of the evaporator can be controlled based on the humidity difference, and the evaporator is used to dehumidify the air. Furthermore, in heating mode, the air heater is activated, allowing air to flow through it. The air heater then heats and dehumidifies the air. Dehumidification is achieved through the evaporator and air heater, reducing the humidity inside the vehicle.

[0043] In an optional embodiment of this application, the step of controlling the air heating device to dehumidify the air and / or controlling the evaporator to reach the target temperature to dehumidify the air based on the humidity difference when the real-time humidity inside the vehicle is greater than the target humidity includes: Sub-step S2071: When the real-time humidity inside the vehicle is greater than the target humidity, obtain the real-time temperature of the evaporator; If the real-time humidity inside the vehicle is higher than the target humidity, dehumidification can be achieved by adjusting the evaporator temperature. The lower the evaporator temperature, the more water vapor in the air will condense into liquid water upon contact with the evaporator, directly reducing the absolute humidity of the air. The real-time temperature of the evaporator can be obtained.

[0044] Sub-step S2072: Based on the humidity difference, reduce the real-time temperature to determine the target temperature; Temperature differences can be pre-mapped to temperature changes to establish a correlation. This correlation determines the temperature change corresponding to the humidity difference. The target temperature is then obtained by subtracting this temperature change from the real-time temperature.

[0045] Sub-step S2073: Control the evaporator to reach the target temperature; and / or, By controlling the evaporator to reach the target temperature, some moisture can be released from the air as it passes through the evaporator, thus reducing humidity.

[0046] Sub-step S2074: Based on the second damper opening corresponding to the humidity difference; When the vehicle is in heating mode, the heater can be used to heat the air, significantly increasing the saturated moisture content. This reduces relative humidity while keeping the total amount of water vapor constant, resulting in drier air. In cooling mode, the heater is not activated for dehumidification; instead, the humidity is controlled by adjusting the target temperature of the evaporator.

[0047] Similarly, the opening degree of the heating damper can be determined as the second damper opening based on the humidity difference mapping. The second damper opening represents the target opening degree of the heating damper. The humidity difference and the opening degree of the heating damper can be calibrated in advance through simulation, experimentation, etc. This application does not limit the specific mapping relationship.

[0048] Sub-step S2075: Control the heater to start and the heating damper to reach the second damper opening degree.

[0049] In the heating mode of the air conditioner, the heater is activated and the heating damper is opened to the second damper position, allowing air to flow through the heater for heating and dehumidification.

[0050] By using an evaporator to dehumidify the air and a heater to directly heat and dehumidify the air, precision and efficiency can be controlled. Furthermore, in cooling mode, the heater can be left off, preventing it from heating and dehumidifying the air and thus avoiding any impact on cooling performance, ensuring the optimal cooling effect of the air conditioning system.

[0051] In summary, for example, based on the implementation process of this application, the humidity control strategy can be shown in Table 1 below: where the real-time humidity inside the vehicle is represented by RH3 and the target humidity is represented by A.

[0052]

[0053] Table 1 This application embodiment responds to a humidity control command by acquiring the real-time humidity inside the vehicle and the target humidity corresponding to the humidity control command; determining the humidity difference between the real-time humidity inside the vehicle and the target humidity; acquiring an internal / external circulation mode; acquiring the internal and external circulation air humidity and the external circulation air humidity in the automatic circulation mode; controlling the internal / external circulation switching device based on the internal and external circulation air humidity; controlling an air humidifier to humidify the air based on the humidity difference when the real-time humidity inside the vehicle is less than the target humidity; and controlling an air heater to dehumidify the air and / or controlling the evaporator to reach the target temperature to dehumidify the air based on the humidity difference when the real-time humidity inside the vehicle is greater than the target humidity. By prioritizing the operation of the internal and external circulation switching device based on the humidity of the internal and external airflow in automatic circulation mode, the humidity of the intake air is adjusted to be closer to the set humidity, thus reducing air conditioning energy consumption. By setting up an on-board humidity system, the difference between the real-time humidity and the target humidity is detected, and the air humidifier is controlled to humidify the air, or the air heater and evaporator are controlled to dehumidify the air at the target temperature. The humidity of the air conditioning can be controlled independently, without relying on temperature control, which can achieve precise control of the humidity inside the vehicle and improve control accuracy. Moreover, since humidity can be controlled directly, avoiding indirect control through temperature, control efficiency can be improved.
