Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a vehicle defogging method and apparatus, electronic equipment, and computer-readable medium. Background Art

[0002] In related technologies, when the ambient temperature is high, cooling defogging is used, resulting in a low air outlet temperature. When the ambient temperature is low, heating defogging is used, resulting in a high air outlet temperature. However, in the ambient temperature range of 0-25 degrees Celsius, where fogging is likely to occur, the air outlet temperature is too low when using cooling defogging and too high when using heating defogging. This leads to poor comfort and defogging effect for pure electric vehicles. Summary of the Invention

These should be considered merely exemplary. Therefore, those skilled in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0028] Where there is no conflict, the various embodiments of the present invention and the features thereof may be combined with each other.

[0029] As used herein, the term “and / or” includes any and all combinations of one or more related enumerated entries.

[0030] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used herein, the singular forms “a” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that when the terms “comprising” and / or “made of” are used in this specification, the presence of the stated feature, integral, step, operation, element, and / or component is specified, but the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof is not excluded.

It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having the meaning consistent with their meaning in the context of the relevant art and the invention, and will not be interpreted as having an idealized or overly formal meaning unless expressly so defined herein.

[0032] In the technical solution of this invention, the collection, storage, use, processing, transmission, provision, and disclosure of user personal information all comply with relevant laws and regulations and do not violate public order and good morals. The use of user data in this technical solution follows relevant national laws and regulations (e.g., the "Information Security Technology - Personal Information Security Specification"). For example: appropriate measures are taken for personal information access control; restrictions are imposed on the display of personal information; the purpose of using personal information does not exceed the scope of direct or reasonable association; and explicit identity targeting is eliminated when using personal information to avoid precisely locating a specific individual.

[0033] In related technologies, when the ambient temperature is high, cooling defogging is used, resulting in a low air outlet temperature. When the ambient temperature is low, heating defogging is used, resulting in a high air outlet temperature. However, in the ambient temperature range of 0-25 degrees Celsius, where fogging is likely to occur, the air outlet temperature is too low when using cooling defogging and too high when using heating defogging. This leads to poor comfort and defogging effect for pure electric vehicles.

[0034] To address at least one of the technical problems existing in the aforementioned related technologies, the present invention provides a vehicle defogging method and apparatus, an electronic device, and a computer-readable medium. Figure 1 This is a schematic flowchart of a vehicle defogging method provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the method includes the following steps:

[0035] Step S101: Obtain the information set of the target vehicle, wherein the information set includes at least: information on the intensity of sunlight shining into the cockpit of the target vehicle, information on the pre-set interior temperature of the target vehicle, information on the temperature of the external environment in which the target vehicle is located, and information on the actual interior temperature of the target vehicle.

[0036] For example, the target vehicle mentioned above can be a pure electric vehicle. The sunlight intensity on the driver's side of the passenger compartment can be collected by a sunlight sensor in the air conditioning system of the pure electric vehicle, and a preset temperature inside the pure electric vehicle can be obtained. The external ambient temperature of the pure electric vehicle can be collected by an ambient temperature sensor in the air conditioning system, and the actual interior temperature of the pure electric vehicle can be collected by an interior temperature sensor in the air conditioning system.

[0037] Step S102: Determine the energy demand information of the target vehicle based on the information set of the target vehicle.

[0038] For example, the energy demand EnergyReq on the driver's side of a pure electric vehicle can be calculated based on the temperature information collected by sensors in the air conditioning system of the pure electric vehicle.

[0039] Step S103: Based on the temperature information of the external environment where the target vehicle is located and the energy demand information of the target vehicle, determine the mode information for defogging the target vehicle.

[0040] For example, the aforementioned defogging mode information for the target vehicle can be divided into three defogging modes: cooling defogging mode, heating defogging mode, and low-load defogging mode. For instance, when the ambient temperature of the pure electric vehicle is less than 2℃ (standard value), the heating defogging mode can be switched to; when the energy demand (EnergyReq) on the driver's side of the pure electric vehicle is less than 350 (standard value varies with ambient temperature), the cooling defogging mode can be switched to; when the energy demand (EnergyReq) on the driver's side of the pure electric vehicle is greater than 350 (standard value varies with ambient temperature) and the ambient temperature of the pure electric vehicle is greater than 2℃ (standard value), the low-load defogging mode can be switched to.

[0041] Step S104: Calculate the target temperature of the air outlet of the target vehicle based on the energy demand information of the target vehicle and the defogging mode information of the target vehicle.

[0042] For example, when a pure electric vehicle is in cooling defogging mode, the target temperature of the air outlet can be calculated based on the energy demand (EnergyReq) on the driver's side; when a pure electric vehicle is in heating defogging mode, the target temperature of the air outlet can also be calculated based on the energy demand (EnergyReq) on the driver's side; and when a pure electric vehicle is in low-load defogging mode, the target temperature of the air outlet can also be calculated based on the energy demand (EnergyReq) on the driver's side.

[0043] Step S105: Defogging is performed on the target vehicle based on the target temperature of the air outlet.

[0044] For example, the operation of the compressor and PTC (heating element) of a pure electric vehicle can be controlled based on the calculated target temperature of the air outlet, thereby achieving defogging treatment of the pure electric vehicle.

[0045] Through the aforementioned steps S101 to S105, by acquiring a set of information about the target vehicle, which includes at least: information on the intensity of sunlight shining into the driver's cabin of the target vehicle, information on the pre-set interior temperature of the target vehicle, information on the temperature of the external environment where the target vehicle is located, and information on the actual interior temperature of the target vehicle; based on the information set of the target vehicle, determining the energy demand information of the target vehicle; based on the temperature information of the external environment where the target vehicle is located and the energy demand information of the target vehicle, determining the defogging mode information of the target vehicle; calculating the target temperature of the air outlet of the target vehicle based on the energy demand information of the target vehicle and the defogging mode information of the target vehicle; and performing defogging treatment on the target vehicle based on the target temperature of the air outlet, this avoids the situation in existing direct cooling and direct heating systems where the air outlet temperature is too low when using cooling for defogging and too high when using heating for defogging, thus allowing the air outlet temperature to be better controlled between 15 and 35 degrees Celsius, thereby improving the comfort of pure electric vehicles during defogging.

[0046] Optionally, in the vehicle defogging method provided in this embodiment of the invention, obtaining the information set of the target vehicle includes: obtaining sunlight intensity information illuminating the driver's cabin of the target vehicle through a sunlight sensor in the air conditioning system of the target vehicle; obtaining the temperature information of the external environment where the target vehicle is located through an ambient temperature sensor in the air conditioning system of the target vehicle; and obtaining the actual interior temperature information of the target vehicle through an interior temperature sensor in the air conditioning system of the target vehicle.

[0047] For example, the air conditioning system of a pure electric vehicle (corresponding to the target vehicle mentioned above) may include the following components: a left sunlight sensor, a right sunlight sensor, an ambient temperature sensor, and an interior temperature sensor. The left and right sunlight sensors in the air conditioning system of the pure electric vehicle can collect the sunlight intensity on the driver's side of the passenger compartment; the ambient temperature sensor in the air conditioning system can collect the external ambient temperature of the pure electric vehicle; and the interior temperature sensor in the air conditioning system can collect the actual interior temperature of the pure electric vehicle.

[0048] In summary, by using sensors in the air conditioning system of a pure electric vehicle, it is possible to quickly and accurately collect data on sunlight intensity, external ambient temperature, and interior temperature.

[0049] Optionally, in the vehicle defogging method provided in this embodiment of the invention, determining the energy demand information of the target vehicle based on the information set of the target vehicle includes: acquiring first weight information, second weight information, third weight information, and fourth weight information, wherein the first weight information is the weight corresponding to the sunlight intensity information shining into the driver's cabin of the target vehicle, the second weight information is the weight corresponding to the pre-set interior temperature information of the target vehicle, the third weight information is the weight corresponding to the temperature information of the external environment where the target vehicle is located, and the fourth weight information is the weight corresponding to the actual interior temperature information of the target vehicle; the energy demand information of the target vehicle is determined based on the sunlight intensity information shining into the driver's cabin of the target vehicle, the pre-set interior temperature information of the target vehicle, the temperature information of the external environment where the target vehicle is located, the actual interior temperature information of the target vehicle, the first weight information, the second weight information, the third weight information, and the fourth weight information.

[0050] For example, the formula for calculating the energy demand of the driver's side of a pure electric vehicle (corresponding to the target vehicle mentioned above) is: EnergyReq(t) = MidVal (intermediate energy value) – Sunload (solar intensity) * K1 + (SetTemp (set temperature) – MidTemp (comfort temperature)) * K2 + OutTemp (external ambient temperature) * K3 + (SetTemp (set temperature) – IncarCompTemp (in-car temperature)) * K4.

[0051] The variables in the above formula for calculating the energy demand on the driver's side are annotated as follows: EnergyReq (energy demand, data range: 0~1000); Sunload (sunlight intensity, which can be collected by a sunlight sensor); SetTemp (set temperature); OutTemp (external ambient temperature, which can be collected by an ambient temperature sensor); and IncarCompTemp (in-vehicle temperature, compensation value, which can be collected by an in-vehicle temperature sensor).

[0052] Additionally, the standardization annotations in the above formula for calculating the energy demand on the driver's side are as follows: MidVal is the median energy value (data range: 0~1000, usually 500); MidTemp is the comfort temperature; K1 is the sunlight intensity weight (corresponding to the first weight information above), for example, it can be 0.3, and generally does not exceed 0.6; K2 is the set temperature weight (corresponding to the second weight information above), for example, it can be 20, and generally does not fall below 10; K3 is the ambient temperature weight (corresponding to the third weight information above), for example, it can be 5; K4 is the in-vehicle temperature weight (corresponding to the fourth weight information above), for example, it can be 30.

[0053] Using the above method, the energy demand information of the driver's side of the pure electric vehicle can be easily calculated based on the collected temperature values.

[0054] Optionally, in the vehicle defogging method provided in this embodiment of the invention, determining the defogging mode information for the target vehicle based on the temperature information of the external environment where the target vehicle is located and the energy demand information of the target vehicle includes: determining whether the temperature of the external environment where the target vehicle is located is lower than a preset temperature; if the temperature of the external environment where the target vehicle is located is lower than the preset temperature, then controlling the target vehicle to be in a first defogging mode; if the temperature of the external environment where the target vehicle is located is not lower than the preset temperature, then determining the defogging mode information for the target vehicle based on the energy demand information of the target vehicle.

[0055] For example, when the ambient temperature of the pure electric vehicle (corresponding to the target vehicle mentioned above) is less than 2°C (standard value) (corresponding to the preset temperature mentioned above), the defogging mode of the pure electric vehicle can be switched to the heating defogging mode (corresponding to the first defogging mode mentioned above); when the ambient temperature of the pure electric vehicle (corresponding to the target vehicle mentioned above) is not less than 2°C (standard value) (corresponding to the preset temperature mentioned above), the driver's side energy demand EnergyReq of the pure electric vehicle (corresponding to the target vehicle mentioned above) can be used to determine which defogging mode the pure electric vehicle (corresponding to the target vehicle mentioned above) is in.

[0056] Using the above method, the defogging mode of a pure electric vehicle can be quickly and accurately determined based on a pre-set external ambient temperature value.

[0057] Optionally, in the vehicle defogging method provided in this embodiment of the invention, determining the defogging mode information for the target vehicle based on the energy demand information of the target vehicle includes: determining whether the energy demand of the target vehicle is less than a preset value; if the energy demand of the target vehicle is less than the preset value, then controlling the target vehicle to be in a second defogging mode; if the energy demand of the target vehicle is not less than the preset value, then controlling the target vehicle to be in a third defogging mode.

[0058] For example, when the ambient temperature of the pure electric vehicle (corresponding to the target vehicle mentioned above) is not less than 2°C (standard value) (corresponding to the preset temperature mentioned above), and when the energy demand EnergyReq of the driver's side of the pure electric vehicle (corresponding to the target vehicle mentioned above) is less than 350 (standard value varies with ambient temperature) (corresponding to the preset value mentioned above), the defogging mode of the pure electric vehicle can be switched to the cooling defogging mode (corresponding to the second defogging mode mentioned above); when the ambient temperature of the pure electric vehicle (corresponding to the target vehicle mentioned above) is not less than 2°C (standard value) (corresponding to the preset temperature mentioned above), and when the energy demand EnergyReq of the driver's side of the pure electric vehicle is greater than 350 (standard value varies with ambient temperature) (corresponding to the preset value mentioned above), the defogging mode of the pure electric vehicle can be switched to the low-load defogging mode (corresponding to the third defogging mode mentioned above).

[0059] Using the above method, based on the calculated energy demand value of the driver's side of the pure electric vehicle, the defogging mode of the pure electric vehicle can be quickly and accurately determined.

[0060] Optionally, in the vehicle defogging method provided in this embodiment of the invention, calculating the target temperature of the target vehicle's air outlet based on the target vehicle's energy demand information and the defogging mode information includes: if the target vehicle is in a first defogging mode, determining a first value based on the target vehicle's energy demand information, and calculating the target temperature of the target vehicle's air outlet based on the first value and the target vehicle's energy demand information; if the target vehicle is in a second defogging mode, determining a second value based on the target vehicle's energy demand information, and calculating the target temperature of the target vehicle's air outlet based on the second value and the target vehicle's energy demand information; if the target vehicle is in a third defogging mode, determining a third value based on the target vehicle's energy demand information, and calculating the target temperature of the target vehicle's air outlet based on the third value and the target vehicle's energy demand information.

[0061] For example, the target temperature control logic of the air outlet in the heating and defogging mode (corresponding to the first defogging mode mentioned above) is: HeatOutTargetTemp=EnergyReq / K5 (corresponding to the first value mentioned above); where the target temperature of the air outlet HeatOutTargetTemp can be obtained by looking up Table 1 according to the energy demand EnergyReq, and Table 1 is the temperature calculation table in the heating and defogging mode, and the intermediate value is a linear interpolation.

[0062] Table 1

[0063]

[0064] The values ​​within the intervals in Table 1 above can be linearly filled.

[0065] For example, the target temperature control algorithm for the air outlet in the cooling defogging mode (corresponding to the second defogging mode mentioned above) is: ColdOutTargetTemp=EnergyReq / AirTemp / K6 (corresponding to the second value mentioned above).

[0066] K6 is a two-dimensional table, as shown in Table 2. The target temperature at the air outlet (ColdOutTargetTemp) is obtained by looking up the energy demand value in Table 2. This allows changes in energy values ​​to reflect variations in different operating conditions, thus ensuring that the target temperature at the air outlet changes accordingly. Furthermore, Table 2 can be modified through calibration.

[0067] Table 2

[0068]

[0069] The values ​​within the intervals in Table 2 above can be linearly filled. During calibration, the parameters can be adjusted appropriately according to changes in ambient temperature; when the ambient temperature is high, the target temperature at the air outlet should be appropriately lower.

[0070] For example, the target temperature control logic of the air outlet in the low-load defogging mode (corresponding to the third defogging mode mentioned above) is: OutTargetTemp=EnergyReq / K7 (corresponding to the third value mentioned above); and the target temperature of the air outlet OutTargetTemp can be obtained by looking up Table 3 according to the energy demand EnergyReq, and Table 3 is the temperature calculation table for the low-load defogging mode, and the intermediate value in Table 3 is a linear interpolation.

[0071] Table 3

[0072]

[0073] Additionally, when the energy demand (EnergyReq) on the driver's side is less than a certain calibrated value, it will be identified as cooling and the target temperature of the air outlet will be output to the thermal management system. When the energy demand (EnergyReq) on the driver's side is greater than a certain calibrated value, it will be identified as heating and the target temperature of the air outlet will be output to the thermal management system.

[0074] Using the above method, the target temperature of the air outlet in each defogging mode can be calculated quickly and accurately.

[0075] Optionally, in the vehicle defogging method provided in this embodiment of the invention, the defogging process of the target vehicle based on the target temperature of the air outlet of the target vehicle includes: obtaining the actual temperature of the air outlet of the target vehicle; controlling the operating state of the compressor and heating element in the target vehicle based on the actual temperature of the air outlet of the target vehicle and the target temperature of the air outlet of the target vehicle; and performing defogging process on the target vehicle based on the operating state of the compressor and heating element in the target vehicle.

[0076] For example, the thermal management system in a pure electric vehicle (corresponding to the target vehicle mentioned above) can control the operation of the compressor and PTC (heating element) based on the air outlet temperature. Furthermore...

[0077] For example, the compressor control algorithm formula is: ΔComp_Spd=Kp(ΔT_(k)–ΔT_(k - 1)+Ki*ΔT_(k)+Kd; compressor speed: Comp_Spd_Ctrl=ΔComp_Spd+Comp_Spd_M; and it is executed once every 100ms.

[0078] For example, if the compressor speed / maximum compressor speed is greater than or equal to the compressor power limit percentage, then the output will be based on the compressor's power limit; otherwise, the output will be based on the calculated result.

[0079] Additionally, the following notes are included in the formula above:

[0080] ΔComp_Spd: Change in compressor speed;

[0081] ΔT_(k): The difference between the target evaporation temperature and the actual evaporation temperature at this moment. The target evaporation temperature during defogging varies with the ambient temperature and is between 4 and 8.

[0082] ΔT_(k - 1): The difference between the set temperature and the actual temperature at the previous moment;

[0083] Comp_Spd_M: Compressor speed at this moment;

[0084] Comp_Spd_Ctrl: The compressor set speed for the next moment;

[0085] Kp / Ki / Kd: Algorithm calibration quantification.

[0086] For example, the control algorithm for a PTC (heating element) is as follows: when the AC (air conditioner) requests heating and demisting or low-load demisting, the PTC setting is controlled based on the difference between the target outlet air temperature and the actual outlet air temperature. Figure 3 This is a schematic diagram illustrating the control settings of the PTC heating element in an embodiment of the present invention, and the control method for controlling the PTC (heating element) is as follows: Figure 3 As shown.

[0087] For example, the defogging modes are classified as follows:

[0088] Low-load dehumidification mode:

[0089] ERV2 valve control strategy: The control target is the difference between the actual outlet air temperature and the target outlet air temperature, and the PID algorithm is used to adjust the opening of ERV2.

[0090] EXV1: A fixed opening value is used based on the ambient temperature to calibrate the test quantity;

[0091] The bypass valve SOV3 is in the open state, the outdoor fan demisting state is on, and the motor circuit water pump is on for heat exchange.

[0092] Cooling and defogging mode:

[0093] When SOV3 is turned on, the refrigerant passes through WCON, then through the electronic expansion valve EXV1, flows through the evaporator, and returns to the compressor via the gas-liquid separator. EXV1 uses WCON outlet subcooling control.

[0094] Heating and defogging mode:

[0095] The refrigerant first passes through the vehicle's condenser, then through the electronic expansion valve ERV2, then through the WCON plate heat exchanger, and finally through SOV4 before returning to the compressor.

[0096] The ERV2 uses ICON in-vehicle condenser outlet subcooling control.

[0097] For example, the temperature damper is controlled as follows:

[0098] When demisting in cooling mode, the temperature damper is controlled at the cold end; when demisting in heating mode, the temperature damper is controlled at the hot end; when demisting under low load, the temperature damper is controlled at the hot end.

[0099] By controlling the operation of the compressor and PTC (heating element) through the above solution, pure electric vehicles can quickly and accurately achieve the defogging effect.

[0100] In summary, through experiments using a low-load demisting mode, with both cooling and heating elements on the hot and cold sides, and an external circulation system (mixed with a 30% internal circulation ratio), the outlet air temperature ranges as follows: 10°C ambient temperature, outlet air temperature range 18-28°C; 15°C ambient temperature, outlet air temperature range 18.5-39.5°C; 20°C ambient temperature, outlet air temperature range 18-44°C; 25°C ambient temperature, outlet air temperature range 18°C ​​and above. The demisting method of bypassing a portion of the refrigerant using a hot gas bypass valve can significantly improve the comfort of demisting in spring and autumn, preventing excessively low outlet air temperature in pure cooling mode and excessively high outlet air temperature in pure direct heating mode.

[0101] Furthermore, a demisting method based on a direct cooling and heating system for new energy vehicles is characterized by three modes: cooling demisting, heating demisting, and low-load demisting. In low-load mode, the refrigerant discharged from the compressor outlet splits into two paths: one path passes through the vehicle's condenser, then through the electronic expansion valve ERV2, and finally through EXV1 into the evaporator; the other path passes through a shut-off valve, through a plate heat exchanger, and then through EXV1 into the evaporator. The electronic expansion valve ERV2 is controlled by the target outlet air temperature, while EXV1 maintains a fixed opening degree depending on the ambient temperature.

[0102] Furthermore, with the intensifying competition in the electric vehicle market, reducing heat pump costs and improving pure electric range, direct cooling and heating systems have gained widespread attention from automakers due to their low cost and high heat exchange efficiency. Currently, direct cooling and heating systems are widely used in battery and passenger compartments. This invention provides a defogging method based on a series-parallel dehumidification system for direct cooling and heating systems, solving the problem of passenger compartment comfort control under low-load defogging conditions and in ambient temperatures ranging from 0-25°C. Existing direct cooling and heating systems use cooling for defogging, resulting in excessively low outlet air temperatures, and heating for defogging, resulting in excessively high outlet air temperatures. This solution can effectively control the outlet air temperature between 15-35°C, improving the comfort of pure electric vehicles during defogging.

[0103] Furthermore, existing technologies use cooling for defogging at higher ambient temperatures, resulting in low outlet air temperatures, and heating for defogging at lower ambient temperatures. However, in the ambient temperature range of 0-25°C, where fogging is prone to occur, cooling defogging results in low outlet air temperatures, while heating defogging results in high outlet air temperatures. This invention provides a defogging method using a direct cooling and heating system, solving the problem of passenger cabin comfort control during low-load defogging in the 0-25°C ambient temperature range. Existing direct cooling and heating systems use excessively low outlet air temperatures for cooling defogging and excessively high outlet air temperatures for heating defogging. This solution can effectively control the outlet air temperature between 15-35°C, improving the comfort of pure electric vehicles during defogging.

[0104] For example, Figure 4 This is a schematic diagram of an air conditioning system in an embodiment of the present invention, such as... Figure 4As shown, the air conditioning system includes the following components: air conditioning control panel, air conditioning controller, air conditioning unit, left sunlight sensor, right sunlight sensor, ambient temperature sensor, and interior temperature sensor.

[0105] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0106] This invention also provides a vehicle defogging device. It should be noted that the vehicle defogging device of this invention can be used to execute the vehicle defogging method provided in this invention. The vehicle defogging device provided in this invention will be described below.

[0107] Figure 5 This is a structural block diagram of a vehicle defogging device provided in an embodiment of the present invention. Figure 5 As shown, the device includes: a first acquisition unit 501, a first determination unit 502, a second determination unit 503, a first calculation unit 504, and a first processing unit 505.

[0108] Specifically, the first acquisition unit 501 is used to acquire an information set of the target vehicle, wherein the information set includes at least: sunlight intensity information shining into the cockpit of the target vehicle, pre-set interior temperature information of the target vehicle, temperature information of the external environment where the target vehicle is located, and actual interior temperature information of the target vehicle.

[0109] The first determining unit 502 is used to determine the energy demand information of the target vehicle based on the information set of the target vehicle;

[0110] The second determining unit 503 is used to determine the defogging mode information for the target vehicle based on the temperature information of the external environment where the target vehicle is located and the energy demand information of the target vehicle.

[0111] The first calculation unit 504 is used to calculate the target temperature of the air outlet of the target vehicle based on the energy demand information of the target vehicle and the defogging mode information of the target vehicle.

A first processing unit 505 performs defogging processing on the target vehicle based on the target temperature of the air outlet. This avoids the situation in existing direct cooling and direct heating systems where the air outlet temperature is too low when using cooling for defogging and too high when using heating for defogging. This allows the air outlet temperature to be better controlled between 15 and 35 degrees Celsius, thereby improving the comfort of pure electric vehicles during defogging.
