In some embodiments, the windows in the passenger compartment may include, but are not limited to, the windshield, rearview mirrors, and vehicle windows, and may also include other windows in the passenger compartment; this application embodiment does not limit this.

In some embodiments, the existence of an anti-fogging requirement in the passenger compartment is determined based on user input information.
[0078] In some embodiments, passenger cabin requirements may also include at least one of the following: cooling requirements, ventilation requirements, sun shading requirements, etc., and may also include other passenger cabin requirements, which shall be set by relevant technicians according to actual needs. This application embodiment does not limit these requirements. Cooling requirements refer to the need to reduce the temperature of the passenger cabin. Ventilation requirements refer to the need to improve the air quality of the passenger cabin. Sun shading requirements refer to the need to reduce direct sunlight in the passenger cabin.
[0079] Step 220: If the passenger compartment requires anti-fog functionality, adjust the operating status of the air conditioning components in the target vehicle.
[0080] The operating status of the air conditioning unit is used to indicate the working condition of each component within the unit. In some embodiments, adjusting the various components of the air conditioning unit enables functions such as heating, cooling, and ventilation. Adjusting the operating status of the air conditioning unit can also meet anti-fogging requirements.
[0081] In some embodiments, glass temperature, vehicle interior temperature, and vehicle interior humidity are acquired. Glass temperature refers to the temperature inside the windshield of the target vehicle, vehicle interior temperature refers to the temperature inside the target vehicle, and vehicle interior humidity refers to the humidity inside the target vehicle. Based on the glass temperature, vehicle interior temperature, and vehicle interior humidity, the probability of fogging of the windshield is obtained. The fogging probability is used to indicate the likelihood of fogging of the windshield. When the ambient temperature of the target vehicle is lower than an ambient temperature threshold, the operating state of the air conditioning components in the target vehicle is adjusted based on the fogging probability. Ambient temperature refers to the temperature of the external environment in which the target vehicle is located.
[0082] In some embodiments, the air conditioning component includes at least one of the following: a humidity sensor, a windshield temperature sensor, and an interior temperature sensor; other sensors may also be included, which are not limited in this application embodiment. A humidity sensor is a sensing device for detecting ambient humidity. In this application embodiment, the humidity sensor is used to detect the interior humidity of the target vehicle. A windshield temperature sensor is a sensing device for detecting the temperature of the windshield. In this application embodiment, the windshield temperature sensor is a sensing device for detecting the temperature of the inside of the windshield. An interior temperature sensor is a sensing device for detecting the temperature inside the target vehicle. In this application embodiment, the interior temperature sensor is used to detect the temperature of the passenger compartment of the target vehicle.
[0083] In some embodiments, the air conditioning assembly includes an air conditioning controller, which controls the operating state of various components within the air conditioning assembly. In some embodiments, the air conditioning controller calculates the probability of fogging on the windshield by analyzing the glass temperature, interior temperature, and interior humidity; and controls the operating state of various components within the air conditioning assembly based on the probability of fogging on the windshield.
[0084] In some embodiments, the glass temperature and in-vehicle humidity are transmitted to the air conditioning controller via a bus. For example, after the windshield temperature sensor collects the glass temperature and the humidity sensor collects the in-vehicle humidity, the data is transmitted to the BCM (Body Control Module) via the LIN (Local Interconnect Network) bus, and then transmitted by the BCM to the air conditioning controller via the CAN (Controller Area Network) bus.
[0085] In some embodiments, the dew point temperature is obtained based on the vehicle interior temperature and humidity, where the dew point temperature is the critical temperature at which fogging begins in the target vehicle; and the probability of fogging of the windshield is obtained based on the dew point temperature, vehicle interior humidity, glass temperature, and vehicle interior temperature.
[0086] Dew point temperature refers to the critical temperature at which water vapor in the air begins to condense into liquid water during the cooling process. When the water vapor in the air reaches saturation, that is, when the humidity inside the car reaches 100%, the excess water vapor will condense into dew. The dew point temperature is the critical temperature at which this process occurs.
[0087] For example, the dew point temperature T d It can be calculated using the following formula:
[0088]
[0089] Where T is the interior temperature and RH is the interior humidity.
[0090] In some embodiments, a fogging probability model is constructed based on dew point temperature, in-vehicle humidity, glass temperature, and in-vehicle temperature. Using this fogging probability model, the fogging probability of the windshield is obtained based on the dew point temperature, in-vehicle humidity, glass temperature, and in-vehicle temperature. The fogging probability model is used to predict the fogging risk of the windshield under different environmental conditions. Optionally, the fogging probability model can be a mathematical model. For example, it can be a linear model, an exponential model, or other mathematical models; this application does not limit the specific methods used to calculate the fogging probability based on dew point temperature, in-vehicle humidity, glass temperature, and in-vehicle temperature.
[0091] Ambient temperature refers to the temperature of the external air surrounding the target vehicle, also known as outside temperature or atmospheric temperature. The ambient temperature threshold refers to the ambient temperature at which fogging is likely to occur, and is preset by relevant technicians based on experimental, calibration data, or predictions. This application does not limit this.
[0092] When the ambient temperature is below 15 degrees Celsius, the vehicle interior does not require cooling; however, the windshield is prone to fogging at this temperature. In related technologies, to prevent fogging, regardless of the number of occupants or the humidity level inside the vehicle, the compressor needs to be continuously running to dehumidify and prevent fogging. The compressor is a high-power load; if it remains on, the vehicle will consume a significant amount of energy due to the compressor's operation.
[0093] In some embodiments, when the probability of fogging is greater than a first fogging threshold, the operating state of the air conditioning component in the target vehicle is adjusted to a first operating state; when the probability of fogging is less than a second fogging threshold, the operating state of the air conditioning component in the target vehicle is adjusted to a second operating state; wherein, the first fogging threshold is greater than the second fogging threshold.
[0094] The first operating state of the air conditioning system refers to the air conditioning mode that prevents or eliminates fogging of the windshield. The second operating state of the air conditioning system refers to the energy-saving air conditioning mode under anti-fogging requirements.
[0095] The first fog threshold refers to the threshold value at which the air conditioning component enters the first operating state. The second fog threshold refers to the threshold value at which the air conditioning component enters the second operating state. In some embodiments, the first and second fog thresholds are parameters obtained by relevant technicians after calibration based on the target vehicle. Due to differences in the space size and airflow field of different vehicles, the first and second fog thresholds will also differ for different vehicle models.
[0096] Step 230: When the passenger compartment requires heating and the target vehicle's operating mode is switched from the first operating mode to the second operating mode, the passenger compartment is heated using the heat from the coolant of the engine corresponding to the first operating mode. The first and second operating modes use different engines to drive the target vehicle.
[0097] The operating mode of the target vehicle refers to the driving mode of the target vehicle under different operating conditions. The first operating mode and the second operating mode of the target vehicle correspond to different driving methods and use different power sources to drive the target vehicle. The power source refers to the energy source that drives the target vehicle, which may include, but is not limited to: internal combustion engine, electric motor, power battery, hybrid power, solar energy, etc., and may also include other power sources, which are not limited in this application embodiment.
[0098] In some embodiments, the target vehicle's operating modes include an internal combustion engine mode and a pure electric mode. The engine includes an internal combustion engine and an electric motor. The internal combustion engine mode refers to the mode in which the target vehicle is driven by an internal combustion engine, and the pure electric mode refers to the mode in which the target vehicle is driven by an electric motor.
[0099] Internal combustion engine mode refers to the target vehicle primarily being powered by an internal combustion engine. An internal combustion engine (ICE), also known as a fuel engine, is an engine that generates energy by burning fuel to drive a vehicle. In some embodiments, the type of internal combustion engine may include, but is not limited to, gasoline engines, diesel engines, turbocharged engines, two-stroke engines, and other types of internal combustion engines; this application embodiment does not limit this. Pure electric mode refers to the target vehicle being powered by an electric motor. An electric motor is an engine that converts electrical energy into mechanical energy to drive the target vehicle.
[0100] In some embodiments, the first operating mode can be an internal combustion engine mode or a pure electric mode. Correspondingly, the second operating mode can be a pure electric mode or an internal combustion engine mode. That is to say, when the target vehicle switches operating modes, although the engine corresponding to the switched operating mode stops operating, the heat generated during operation has not yet dissipated. The remaining heat of the engine corresponding to the switched operating mode can be used to heat the passenger compartment, reducing the heating power consumption of the heating core or high-voltage electric heater, thus achieving energy saving.
[0101] In summary, the technical solution provided in this application, by adjusting the operating status of the air conditioning components in the target vehicle according to the passenger compartment requirements, or by using the heat from a paused engine to heat the passenger compartment, achieves the goal of meeting passenger compartment requirements with less energy consumption by adopting appropriate strategies based on different passenger compartment requirements, thereby improving the target vehicle's range.
[0102] The following section introduces thermal management strategies for anti-fog requirements.
[0103] In some embodiments, the first operating state and the second operating state of the air conditioning component can be implemented based on thermal management strategy one and / or thermal management strategy two.
[0104] I. Thermal Management Strategy
[0105] In some embodiments, when the air conditioning unit enters a first operating state, the compressor in the air conditioning unit is turned on; when the air conditioning unit enters a second operating state, the compressor in the air conditioning unit is turned off.
[0106] The compressor is a device in an air conditioning system used for refrigeration.
[0107] For example, please refer to Figure 3 The diagram illustrates a flowchart of a thermal management strategy provided in one embodiment of this application. Glass temperature and in-vehicle humidity are transmitted to the air conditioning controller via a bus. Exemplarily, after the windshield temperature sensor collects the glass temperature and the humidity sensor collects the in-vehicle humidity, they are transmitted to the BCM via the LIN bus, and then the BCM transmits the data to the air conditioning controller via the CAN bus. After the in-vehicle temperature sensor collects the in-vehicle temperature, it transmits the in-vehicle temperature to the air conditioning controller. The air conditioning controller calculates the probability of fogging on the windshield based on the glass temperature, in-vehicle temperature, and in-vehicle humidity. If the fogging probability is greater than a first fogging threshold, indicating a risk of fogging on the windshield, the air conditioning system enters a first operating mode and activates the compressor. If the fogging probability is less than a second fogging threshold, indicating no risk of fogging on the windshield, the air conditioning system enters a second operating mode and deactivates the compressor.
[0108] The first thermal management strategy assesses the risk of fogging based on the probability of fogging. When a fogging risk exists, the compressor is activated. As the compressor operates, the humidity inside the vehicle decreases. Once the humidity drops to a level where there is no risk of fogging, the compressor is deactivated. By activating and deactivating the compressor based on the fogging probability, it avoids continuous operation, significantly reducing the energy consumption associated with the compressor.
[0109] II. Thermal Management Strategy Two
[0110] When the ambient temperature is below 15 degrees Celsius, the target vehicle has a heating requirement. However, at this temperature range, fogging is very likely to occur. In related technologies, the air conditioning system uses a full external circulation mode to prevent fogging. However, if the air conditioning system uses a full external circulation mode, the large amount of cold air entering the target vehicle due to the cold outside air is not conducive to the rise of the interior temperature.
[0111] In some embodiments, the air intake ratio of the internal and external circulation of the air conditioning unit is adjusted.
[0112] In some embodiments, the air conditioning unit further includes an external circulation damper and an internal circulation damper. In some embodiments, the ratio of internal to external air intake of the air conditioning unit is adjusted by controlling the opening size of the external circulation damper and the internal circulation damper.
[0113] In some embodiments, when the air conditioning unit enters a first operating state, the air intake ratio of the internal and external circulation of the air conditioning unit is adjusted to a defogging air intake ratio; when the air conditioning unit enters a second operating state, the air intake ratio of the internal and external circulation of the air conditioning unit is adjusted to an energy-saving air intake ratio.
[0114] The defogging air intake ratio is a pre-set ratio of internal and external air intake for the air conditioning unit in a first operating state. For example, the defogging air intake ratio could be 100% external air intake. The energy-saving air intake ratio is a pre-set ratio of internal and external air intake for the air conditioning unit in a second operating state. For example, the energy-saving air intake ratio is 50% external air intake and 50% internal air intake. Another example is 40% external air intake and 60% internal air intake. In some embodiments, the proportion of external air intake in the defogging air intake ratio is higher than the proportion of external air intake in the energy-saving air intake ratio. It should be noted that the above-mentioned defogging air intake ratio and energy-saving air intake ratio are merely exemplary, and those skilled in the art can set them according to their needs; this application embodiment does not limit this.
[0115] For example, please refer to Figure 4The document illustrates a flowchart of a second thermal management strategy provided in one embodiment of this application. After the target vehicle is started, the air intake ratio for internal and external circulation is set to an energy-saving air intake ratio. Glass temperature and interior humidity are transmitted to the air conditioning controller via a bus. Exemplarily, after the windshield temperature sensor collects the glass temperature and the humidity sensor collects the interior humidity, they are transmitted to the BCM via the LIN bus, and then the BCM transmits the data to the air conditioning controller via the CAN bus. After the interior temperature sensor collects the interior temperature, it transmits the interior temperature to the air conditioning controller. The air conditioning controller determines the probability of fogging on the windshield based on the glass temperature, interior temperature, and interior humidity. If the fogging probability is greater than a first fogging threshold, indicating a risk of fogging on the windshield, the air conditioning system enters a first operating mode, setting the air intake ratio for internal and external circulation to a defogging air intake ratio. If the fogging probability is less than a second fogging threshold, indicating no risk of fogging on the windshield, the air conditioning system enters a second operating mode, setting the air intake ratio for internal and external circulation to an energy-saving air intake ratio.
[0116] When there is no risk of fogging on the windshield, thermal management strategy two uses a hybrid internal and external air circulation method for air intake. When there is a risk of fogging, a full external air circulation method is used for air intake, which improves the efficiency of heating the passenger compartment.
[0117] The following section introduces thermal management strategies for heating needs.
[0118] In some embodiments, the thermal management components of the target vehicle include: a high-voltage electric heater, a heat exchanger for the power battery, a first three-way valve, and a second three-way valve; the first three-way valve includes a first valve port, a second valve port, and a third valve port, the first valve port being connected to the internal combustion engine, the second valve port being connected to the inlet of the high-voltage electric heater, and the third valve port being connected to the outlet of the heating core of the passenger compartment; the second three-way valve includes a fourth valve port, a fifth valve port, and a sixth valve port, the fourth valve port being connected to the outlet of the high-voltage electric heater, the fifth valve port being connected to the inlet of the heating core of the passenger compartment, and the sixth valve port being connected to the heat exchanger of the power battery; the high-voltage electric heater includes an outlet temperature sensor for measuring the temperature of the outlet of the high-voltage electric heater.
[0119] A high-voltage electric heater (HVH) is a device that provides heat energy through the high-voltage electrical system of a target vehicle. In some embodiments, the high-voltage electric heater is powered by direct current high voltage. In some embodiments, the high-voltage electric heater includes at least one of the following functions: passenger compartment heating, power battery heating, drive system temperature control, etc., and may also include other functions, which are not limited in this application embodiment.
[0120] A power battery is a power source used to provide power to a target vehicle. The power battery can provide electrical energy to an electric motor to drive the target vehicle. A heat exchanger in a power battery refers to a device that transfers heat from the coolant in the power battery to other media. In some embodiments, the type of heat exchanger may include, but is not limited to: liquid-cooled heat exchangers, air-cooled heat exchangers, phase change material heat exchangers, etc., and may also include other heat exchangers with specific requirements; this application does not limit this aspect.
[0121] A three-way valve is a valve used for fluid control, whose main function is to change the direction of fluid flow or to distribute fluid flow. A three-way valve has three ports, including one inlet and two outlets. In some embodiments, the type of three-way valve may include, but is not limited to, three-way solenoid water valves, electric three-way valves, manual three-way valves, etc., and may also include other types of three-way valves; this application does not limit this.
[0122] III. Thermal Management Strategy Three
[0123] In some embodiments, the components of the thermal management assembly are connected by pipes.
[0124] (a) Switching from internal combustion engine mode to pure electric mode
[0125] In some embodiments, when the first operating mode is the internal combustion engine mode, the first three-way valve is opened, allowing the first coolant of the internal combustion engine to flow through the first three-way valve, the second three-way valve, and the high-pressure electric heater, and reach the heating core of the passenger compartment; the passenger compartment is heated by the heat of the first coolant through the heating core.
[0126] The first coolant refers to the liquid used to cool the internal combustion engine, absorbing and removing excess heat generated during engine operation. Optionally, the type of the first coolant may include at least one of the following: water, inorganic acid salt coolant, organic acid salt coolant, mixed coolant, and may also include other types, which are not limited in this embodiment.
[0127] A heating core is a device used to heat liquids or gases to provide a heating function.
[0128] For example, please refer to Figure 5This illustration shows a schematic diagram of a portion of the heating circuit of a thermal management system provided in one embodiment of this application. When the target vehicle's operating mode changes from internal combustion engine mode to pure electric mode, the internal combustion engine 510 is shut off, and the first three-way valve 520 is opened. The first three-way valve 520 includes three valve ports: a first valve port 521, a second valve port 522, and a third valve port 523. After the first three-way valve 520 is opened, the first coolant flows out from the internal combustion engine 510, flows into the first three-way valve 520 through the first valve port 521, and then flows out from the second valve port 522. After flowing out from the first three-way valve 520, the first coolant flows into the second three-way valve 530 through the fourth valve port 531, and then flows out from the fifth valve port 532 and the sixth valve port 533 of the second three-way valve 530. The first coolant flowing out from the fifth valve port 532 reaches the heating core 540, and the heating core 540 uses the heat of the first coolant to heat the passenger compartment.
[0129] (II) Switching from pure electric mode to internal combustion engine mode
[0130] In some embodiments, when the first operating mode is pure electric mode, the first three-way valve is opened, allowing the first medium to flow through the first three-way valve, the second three-way valve, and the high-pressure electric heater, reaching the heating core of the passenger compartment; the passenger compartment is heated by the heat of the first medium through the heating core; wherein, the power battery is used to provide electrical energy to the electric motor, and the heat exchanger of the power battery is used to transfer the heat of the second coolant of the power battery to the first medium.
[0131] The second coolant is a liquid used to ensure the safe operation of the power battery. In some embodiments, the type of the second coolant may include, but is not limited to, water-based coolant, oil-based coolant, and phase change material coolant, and may also include other types, which are not limited in this application embodiment. The first medium refers to the medium in the pipes of the heating circuit of the thermal management system, used to transfer heat.
[0132] For example, please refer to Figure 5 When the target vehicle's operating mode switches from pure electric mode to internal combustion engine mode, the electric motor is turned off, and the first three-way valve 520 is opened. The second coolant in the power battery 550, which provides power to the electric motor, flows into the heat exchanger 560 of the power battery. The heat exchanger 560 transfers the heat of the second coolant to the first medium, which flows into the first three-way valve 520 through the third valve port 523, and then flows out through the second valve port 522. After flowing out of the first three-way valve 520, the first medium flows into the second three-way valve 530 through the fourth valve port 531, and then flows out through the fifth valve port 532 and the sixth valve port 533. The first coolant flowing out from the fifth valve port 532 reaches the heating core 540, which uses the heat of the first medium to heat the passenger compartment.
[0133] In some embodiments, when the temperature at the outlet of the high-pressure electric heater is less than a first threshold, the first three-way valve is closed and the high-pressure electric heater is turned on. In some embodiments, when the temperature at the outlet of the high-pressure electric heater is less than the first threshold, the high-pressure electric heater is in a closed state.
[0134] In some embodiments, an outlet temperature sensor is provided at the outlet of the high-pressure electric heater, and the outlet temperature sensor is used to detect the temperature of the liquid flowing out of the high-pressure electric heater.
[0135] When the target vehicle switches operating modes, the residual heat of the coolant from the idled engine is used to heat the passenger compartment. The high-pressure electric heater is turned on only when the outlet temperature is below the first threshold, and the first three-way valve is closed at the same time to prevent the colder engine coolant from participating in the circulation, thereby reducing the power output of the high-pressure electric heater and achieving energy saving.
[0136] In some embodiments, hot water heated by a high-voltage electric heater enters the heater core of the crew compartment for heat exchange and heating.
[0137] In some embodiments, the thermal management system further includes a blower for driving the flow of air or other gases. For example, in the thermal management system, the blower is used to deliver cooled or heated air into the passenger compartment.
[0138] Case 1: The heating power of the HVH is very high, and the outlet water temperature is very high. The water temperature entering the heater core inside the HVAC is also very high, but the air volume of the blower inside the HVAC is relatively small.
[0139] Case 2: The heating power of the HVH is lower than that of Case 1, the outlet water temperature is lower than that of Case 1, and the water temperature entering the heater core inside the HVAC is lower than that of Case 1, but the air volume of the blower inside the HVAC is greater than that of Case 1.
[0140] The Case 2 strategy has a higher heat exchange efficiency than Case 1. Furthermore, since the HVH is a high-power electrical device, increasing the HVH power to raise the water temperature while reducing the blower airflow consumes more energy than reducing the HVH power to lower the water temperature while increasing the blower airflow. Therefore, the Case 2 solution is more energy-efficient while achieving the same heating effect.

The first coolant is then used in the heating core to heat the passenger compartment. The heat from the liquid heats the passenger compartment; when the first operating mode is the pure electric mode, the first three-way valve is opened, allowing the first medium to flow through the first three-way valve, the second three-way valve, and the high-pressure electric heater, reaching the heating core of the passenger compartment; the passenger compartment is heated by the heat from the first medium through the heating core; wherein, the power battery is used to provide electrical energy to the electric motor, and the heat exchanger of the power battery is used to transfer the heat of the second coolant of the power battery to the first medium; when the temperature at the outlet of the high-pressure electric heater is less than a first threshold, the first three-way valve is closed, and the high-pressure electric heater is turned on.
[0148] In some embodiments, the air conditioning adjustment module 620 includes a data acquisition submodule, a probability calculation submodule, and an air conditioning adjustment submodule.
