[0043] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0044] In order to solve the problem that when the vehicle is driving, it is necessary to turn on the internal circulation mode and the external circulation mode at the same time, and additional cooling or heating equipment is needed to increase the energy consumption of the vehicle. The present application provides the following embodiments to solve the above problem:

[0045] This embodiment provides a vehicle air conditioning control method, such as Figure 1 FIG. 1 is a flowchart of the method of this embodiment, and the method of this embodiment may specifically include the following steps:

[0046] Step 101 , in response to a user's required temperature, obtaining a first air inlet temperature of the vehicle's air conditioner in an internal circulation mode and a second air inlet temperature in an external circulation mode.

[0047] When confirming the user's required temperature, the required temperature is obtained by identifying the request information sent by the user to the vehicle's control terminal through the terminal or screen inside the vehicle. The request information contains the required temperature of the air conditioner required by the user, and confirms the air inlet temperature value of the circulating air conditioner at this ambient temperature. It should be understood that the vehicle's air conditioning is divided into circulation modes, which can be internal circulation mode and external circulation mode. The internal circulation mode refers to an air conditioning mode that allows air to circulate only in the car, and the external circulation mode refers to an air conditioning mode that connects the air inside the car with the outside air. After confirming the ambient temperature outside the vehicle, the air inlet temperature values ​​of the vehicle's internal circulation mode and external circulation mode can be quickly confirmed.

[0048] Step 102 , determining whether the required temperature is an extreme value among the required temperature, the first inlet air temperature and the second inlet air temperature.

[0049] In this embodiment, after the required temperature is confirmed, the magnitude relationship between the required temperature and the first inlet air temperature and the second inlet air temperature is quickly confirmed, so as to confirm whether the required temperature is a maximum value or a minimum value among the three.

[0050] Step 103, if yes, control the air conditioner to operate in an air conditioning mode corresponding to the inlet air temperature closest to the required temperature, the inlet air temperature includes: a first inlet air temperature or a second inlet air temperature, and the air conditioning mode includes: an internal circulation mode or an external circulation mode.

[0051] After confirming whether the required temperature is an extreme value among the three, the vehicle air conditioning is activated using the air conditioning mode corresponding to the air inlet temperature closest to the required temperature. By adopting the technical solution of this embodiment, a single air conditioning mode that best matches the user's required temperature can be quickly selected based on the required temperature. For example, in spring and autumn, the required temperature selected by the user will not have a large difference value with the first air inlet temperature or the second air inlet temperature. Therefore, when the first air inlet temperature and the second air inlet temperature do not meet the required temperature, the air conditioning mode corresponding to the air inlet temperature closest to the required temperature can be directly selected to control the vehicle air conditioning and meet the user's temperature requirements.

[0052] By adopting the technical solution of this embodiment, it is possible to operate in an air-conditioning mode with an inlet air temperature closest to the required temperature, without using the air-conditioning refrigeration equipment to provide a cold source and without using the heating device to provide a heat source as much as possible. Only relying on a single air-conditioning mode, the output temperature can meet the user's temperature requirements, thereby saving vehicle energy while maintaining the user's driving experience.

[0053] In a possible embodiment, after determining whether the required temperature is an extreme value between the required temperature, the first inlet air temperature, and the second inlet air temperature, the method further includes:

[0054] If not, the vehicle's air conditioning is controlled according to the internal circulation mode and the external circulation mode.

[0055] In the present embodiment, a possible situation is considered, that is, the required temperature is in the middle of the required temperature, the first air inlet temperature and the second air inlet temperature, and a single air conditioning mode is difficult to meet the user's required temperature. In this case, the present embodiment proposes to use a combination of the internal circulation mode and the external circulation mode to achieve that the final output temperature of the air conditioner meets the user's temperature requirement.

[0056] By adopting the content of this embodiment, considering that the user's required temperature cannot be met by a single air conditioning mode, two air conditioning modes can be combined so that the final output temperature can meet the demand. Among them, in an existing air conditioning control method, when a single internal circulation mode and an external circulation mode cannot output the user's required temperature, it is necessary to control the air conditioning mode to be combined with a heating or cooling device to output the required temperature. However, outputting the required temperature in this way requires additional energy consumption of the vehicle. The two air conditioning modes of the technical solution of this embodiment are combined to generate corresponding temperature values, which can avoid the need to further enable the heating or cooling device when turning on the air conditioner, and can further save the vehicle's energy when meeting the user's required temperature.

[0057] In a possible embodiment, the air conditioning control of the vehicle is performed according to the internal circulation mode and the external circulation mode, including:

[0058] Adjust the air door opening of the internal circulation mode and / or the air door opening of the external circulation mode.

[0059] In the technical solution of this embodiment, a specific description is given of the specific matching method of the internal circulation mode and the external circulation mode, that is, by adjusting the damper opening of the internal circulation mode and / or the damper opening of the external circulation mode respectively, the air volume of the internal circulation mode and the external circulation mode of the air conditioner is adjusted, so as to meet the final output temperature equal to the user's required temperature. Among them, the damper opening adjustment of different air conditioning modes can be adjusted simultaneously according to the required temperature, or after the dampers are opened at the same time, only the damper of a certain air conditioning mode is adjusted.

[0060] By adopting the technical solution of this embodiment, it is possible to specifically realize the combination of the internal circulation mode and the external circulation mode, adjust the air door opening of different air conditioning modes, so that the air volume of the internal circulation mode and the external circulation mode is combined with each other, and the required temperature value is generated using the first air inlet temperature and the second air inlet temperature. The technical solution of this embodiment further discloses the feasibility of satisfying the user's required temperature by relying solely on the air conditioning mode, thereby meeting the energy-saving needs of the vehicle.

[0061] In a possible embodiment, controlling the damper opening of the internal circulation mode and / or the damper opening of the external circulation mode includes:

[0062] According to the current damper opening of the internal circulation mode and / or the current damper opening of the external circulation mode, the internal circulation mode and / or the external circulation mode are adjusted to output the mixed air temperature value; the mixed air temperature value is compared with the required temperature to generate a temperature error value; it is calculated whether the temperature error value is greater than a preset error value; if the temperature error value is greater than the preset error value, the damper opening of the current internal circulation mode and / or the damper opening of the current external circulation mode are adjusted until the temperature error value is less than the preset error value, and the air conditioning control of the vehicle is performed.

[0063] In the content of this embodiment, a process for verifying the mixed air temperature value is proposed. Specifically, before the internal circulation mode and the external circulation mode are combined to meet the user's required temperature, the mixed air temperature value outputted may not meet the required temperature. Therefore, it is necessary to continuously identify the mixed air temperature value to confirm that it is finally close to the required temperature. If it is identified that the difference between the mixed air temperature value and the required temperature is too large, it is necessary to continuously adjust the internal circulation mode and / or the external circulation mode so that the temperature error value between the mixed air temperature value outputted by it and the required temperature value is within the preset error value range. Exemplarily, when the preset error value is 1°C, it is necessary to continuously verify whether the temperature error value between the mixed air temperature value and the required temperature value is greater than 1°C. If it exceeds 1°C, it is necessary to further adjust the damper opening of the current internal circulation mode that generates the mixed air temperature value and / or the damper opening of the current external circulation mode until the temperature difference between the mixed air temperature value and the required temperature is less than 1°C.

[0064] In a possible embodiment, before obtaining the first air inlet temperature of the vehicle air conditioner in the internal circulation mode and the second air inlet temperature in the external circulation mode in response to the user's required temperature, the method further includes:

[0065] Identify the ambient temperature outside the vehicle; when the ambient temperature is lower than the preset temperature value, control the air conditioner to operate in internal circulation mode and turn on the air conditioner's heating device.

[0066] The content of this embodiment takes into account that when the external ambient temperature of the vehicle is too low, for example, when the current season is winter, when the vehicle recognizes the low temperature signal from the outside, the vehicle only turns on the internal circulation mode of the air conditioner to reduce the heat loss inside the vehicle. At the same time, on the basis of turning on a single internal circulation in this embodiment, the heating device of the air conditioner can be further turned on to cooperate with the internal circulation mode of the air conditioner to increase the temperature inside the vehicle, so that when the external temperature of the vehicle is low, the temperature required by the user can be reached to ensure the riding experience of the vehicle occupants.

[0067] In a possible embodiment, when the ambient temperature is lower than a preset temperature value, the air conditioner is controlled to operate in an internal circulation mode and a heating device of the air conditioner is turned on, including:

[0068] When the ambient temperature is lower than the preset temperature value, the air conditioner is controlled to operate in the internal circulation mode, and the heating power of the air conditioner's heating device is confirmed according to the required temperature; the humidity information inside the vehicle is identified; through the comparison result of the humidity information and the preset humidity value, the heating strategy for the vehicle's passenger compartment glass is output, and the passenger compartment glass is heated according to the heating strategy.

[0069] When only the internal circulation mode is used to control the vehicle's air conditioning, once there is a temperature difference between the inside and outside of the vehicle's windows, fogging may occur on the low-temperature glass surface due to the high humidity of the air on the window glass surface and the window glass temperature reaching the dew point temperature under the humidity. At this time, the fogging of the window will interfere with the driver's field of vision and cause a safety hazard to driving. Therefore, the technical solution of this embodiment further proposes that when the internal circulation mode of the air conditioner is turned on and the heating device of the air conditioner is enabled, the humidity information of the air inside the vehicle is identified, the risk of fogging of the window is determined based on the humidity information inside the vehicle, and the heating strategy for the passenger compartment glass of the vehicle is output based on the risk of fogging of the window, and the heating function of the window is enabled through the heating strategy, wherein the heating strategy includes the heating method, heating temperature and heating time for the window. The heating method may be heating by means of a heating device installed on a vehicle window at a fixed position. For example, the glass body of the vehicle window may be directly heated, wherein the glass is directly heated to defrost and remove dew. Compared with the existing technical solution of blowing air to the vehicle window through an air duct, direct heating of the glass conducts heat more rapidly, and at the same time, the utilization rate of heat acting on the vehicle window is higher. The heating temperature and heating time are determined based on the risk level of fogging of the vehicle window. The higher the risk level of fogging of the vehicle window, the higher the heating temperature and the longer the heating time of the vehicle window.

[0070] In the existing vehicle air conditioning, in order to achieve the purpose of energy saving, generally start from two directions. One is to improve the energy efficiency ratio of the air conditioning system, that is, to use less energy and obtain more heat. This is why different models on the market are equipped with different forms of heat pump systems. However, the air conditioning system also shoulders the demand for summer cooling, so the currently popular CO 2 Although the heat pump system can improve winter heating, it cannot be widely promoted due to its weak cooling performance. Another energy-saving direction is to reduce the winter heating load of the air conditioning system. In most models, part of the internal circulation will be introduced during winter heating to increase the temperature of the air inlet of the air conditioning box. Assuming that the passenger compartment needs the same air volume and air outlet temperature, the heat required by the air conditioning system will be greatly reduced due to the increase in the inlet air temperature. At this time, the proportion of mixing into the internal circulation is more important. Since a larger proportion of internal circulation is mixed, the glass of the passenger compartment will be more likely to fog, causing safety problems. Therefore, most vehicles can only mix 30% to 50% of the internal circulation in winter -7℃ working conditions. If the model uses a more advanced double-layer flow box, the air blown into the defrost channel will be drier and less likely to fog. Therefore, some models can mix 70% of the internal circulation, but they cannot further increase the proportion of the internal circulation.

[0071] When adopting the technical solution of this embodiment, in spring and autumn seasons, when the dependence on heating or cooling equipment is not serious, the single air-conditioning mode can be directly used to meet the required temperature of vehicle users. When the single air-conditioning mode cannot meet the user's needs, the combination of internal and external circulation modes can be further relied on to output the required temperature. In extreme seasons, such as summer and winter, the external circulation mode of the air conditioner is directly turned off to prevent heat exchange between the inside and outside of the vehicle. The full internal circulation is adopted, and the heating or cooling equipment is further combined to ensure the user's riding experience. At the same time, as Figure 2 In the existing schematic diagram of the vehicle structure for defrosting shown, in order to realize blowing air to the window through the defrosting air duct, it is necessary to arrange a special main defrosting air duct, main and co-pilot side defrosting air ducts, and a defrosting air door motor. By adopting the method of directly heating the glass, the above-mentioned air ducts and motors can be cancelled, the air-conditioning box can be streamlined, and the vehicle weight can be reduced.

[0072] Regarding the content of the above embodiment, this embodiment further proposes a logic diagram for determining the air-conditioning mode, as Figure 3 shown. After determining the target outlet air temperature (i.e., the required temperature) T0, determine the first inlet air temperature T2 and the second inlet air temperature T1, and compare T0, T1, and T2. When it is confirmed that T0 is an extreme value and T0 is not between T1 and T2, determine the inlet air temperature closest to T0, and use the circulation mode corresponding to the closest inlet air temperature as the target air-conditioning mode. For example, when T0 < T1 and T0 < T2, T0 is a minimum value. At this time, when T1 - T0 ≥ T2 - T0, T2 is closer to T0, and the internal circulation mode corresponding to T2 is used as the target air-conditioning mode to control the operation of the air conditioner; when T1 - T0 ≤ T2 - T0, T1 is closer to T0, and the external circulation mode corresponding to T1 is used as the target air-conditioning mode to control the operation of the air conditioner. When T0 is the intermediate value of T0, T1, and T2, the internal circulation mode and the external circulation mode jointly generate a mixed air temperature value T3, and calculate the temperature error value between T3 and T0. In this embodiment, the temperature error value is set to 1, that is, it is judged whether T0 and T3 satisfy T0 - 1 ≤ T3 ≤ T0 + 1. If not, further adjust the air door positions of the internal circulation mode and / or the external circulation mode, change the air door opening, until T3 satisfies T0 - 1 ≤ T3 ≤ T0 + 1.

[0073] Regarding the content of the above embodiment, this embodiment further proposes a method flow chart for outputting a heating strategy, as Figure 4As shown, when the air conditioner receives a heating command, it activates the heating device, identifies whether the vehicle's external temperature is below 0°, and turns on the automatic circulation of the air conditioner. The hybrid automatic voltage controls the HVAC circulation motor to switch the air conditioner mode to full internal circulation, that is, only turns on the internal circulation mode, and identifies the humidity of the air inside the car. According to the specific humidity value inside the car, the risk level of fogging or frost on the window is confirmed, and the heating gear for turning on the window heating is selected according to the risk level. Among them, the heating output heat value and duration of different heating gears are different. When the humidity value of the window glass drops to a certain level and the humidity value does not change for a period of time, the heating is stopped.

[0074] This embodiment further proposes a vehicle air conditioning system structure diagram, such as Figure 5 As shown, it includes a thermal management controller, multiple sensors (external temperature sensor, internal temperature sensor, temperature and humidity sensor), HU controller (user operation interface), heating device (WPTC, APTC and heat pump system and other devices that provide heat source for air conditioning), HVAC circulation motor, front windshield heating device, and driver and passenger glass heating device. As the core of control, the thermal management controller communicates with the external temperature sensor, internal temperature sensor, temperature and humidity sensor and sunlight sensor through Lin, PWM and other communication methods or hard-wired direct connection to determine the current external working conditions of the vehicle; then, through the HU controller, it collects the user's demand status for the air-conditioning system at this time, including but not limited to the set temperature, Auto cycle status, etc.; based on the above information, the thermal management controller calculates whether the passenger compartment glass needs to be heated at this time. If heating is required, it controls the heating device of the air-conditioning system through CAN / Lin / PWM and other communication methods to heat according to the heating strategy, and adjusts the HVAC circulation damper state to change to full internal circulation; at the same time, it monitors the value of the temperature and humidity sensor and calculates the fogging risk at this time. If the fogging risk is greater than 0, the front windshield heating device and the driver and co-driver side glass heating device are controlled to use different heating powers for defog according to different temperature and humidity conditions.

[0075] In realization Figure 4In the cooling and heating demand of the embodiment, the whole vehicle comprehensively calculates the cooling and heating demand of the user at this time based on the external temperature sensor, the internal temperature sensor and the air-conditioning temperature setting. When the calculation result is a heating request, the heating device in the air-conditioning system is operated by the thermal management controller (the heating device includes air-heating PTC, WPTC and air-conditioning heating methods such as heat pump air-conditioning), and the HVAC circulation damper is adjusted to full internal circulation at the same time. The value of the temperature and humidity sensor is detected at all times to determine whether there is a risk of fogging. If the fogging risk is greater than 0, the thermal management controller sends a 1st-level heating request to the front windshield and the main and passenger side glass heating device. If the fogging risk is reduced to 0 and the duration is ≥ T1, T1 is the safe time without fogging, the front air duct heating device and the main and passenger side glass heating device are turned off; if the humidity value further increases to b, a 2nd-level heating request is sent, b is the humidity threshold for triggering the 2nd heating request, and so on. It is preliminarily defined that there are 3 heating levels, and each heating level is set according to the different humidity values ​​in the vehicle. The number of heating levels and the power size can be adjusted later according to the actual calibration of the whole vehicle.
