Description

Technical Field

[0002] In related technologies, under cold weather conditions, the heating system of a vehicle's air conditioning system can utilize the engine and heater as heat sources, then heat the cold air to the user-set temperature through the radiator, and evenly distribute it into the vehicle's interior space through the air vents. However, factors such as the ambient temperature inside and outside the vehicle, sunlight exposure, and the engine's operating status can all affect the heat exchange stability of the heating system, leading to fluctuations in the air outlet temperature. This causes passengers to experience sudden changes in temperature, affecting driving and riding comfort. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a control method for vehicle air conditioning that can reduce fluctuations in the outlet air temperature and improve the stability of the outlet air temperature.

[0004] The present invention also proposes a vehicle controller, an in-vehicle air conditioning system, a vehicle, electronic equipment, and a computer-readable storage medium.

[0006] When the vehicle is started, the initial ambient temperature outside the vehicle and the initial heat load of the vehicle are obtained;

[0007] Obtain the first current ambient temperature outside the vehicle and the base value of the opening of the temperature damper;

[0008] When the initial ambient temperature is not within the preset first temperature range and the first current ambient temperature is less than or equal to the minimum value of the first temperature range, the current heat load of the vehicle is obtained.

[0009] When the initial heat load is not within the preset load range and the current heat load is greater than or equal to the maximum value of the load range, the opening compensation value of the temperature damper is obtained based on the current heat load and the first current ambient temperature.

[0010] The second current ambient temperature outside the vehicle is detected at preset time intervals.

[0011] When the first current ambient temperature is within the preset second temperature range, or when the first current ambient temperature is not within the second temperature range and the second current ambient temperature is less than or equal to the minimum value of the second temperature range, the engine downtime of the vehicle is detected and recorded.

[0012] When the downtime is greater than or equal to a preset time threshold, the preset opening protection value of the temperature damper is obtained;

This allows for real-time sensing of changes in external environmental conditions. By comprehensively considering the impact of engine operating status changes and environmental condition changes on the heating system, and using the current heat load and the first current ambient temperature, a temperature damper opening compensation value is obtained. Based on the acquired opening base value, opening compensation value, and preset opening protection value, the opening of the temperature damper is controlled. This enables automatic adjustment of the temperature damper opening as operating conditions change, ensuring that the heating system provides a stable outlet air temperature under different environmental conditions.

[0065] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0066] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0067] In the description of this invention, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features or their sequential relationship.

[0068] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0069] Understandably, the engine is one of the key heat sources for the heating system. Specifically, the waste heat from the engine coolant and the heating from the heater core together provide sufficient heat for the heater core, and the heated air flows into the passenger compartment through the vents. However, when the engine stops running, the heat source of the heating system weakens, directly leading to a decrease in heating capacity and consequently a drop in the air outlet temperature. Furthermore, external environmental factors such as a drop in ambient temperature inside and outside the vehicle, and reduced sunlight intensity, all weaken the heat exchange efficiency of the heating system. For example, in extremely cold, overcast conditions, the heating system needs to output more heat to overcome the impact of the low outside temperature on the interior temperature, causing the system to operate under high load. This increases the instability of the air outlet temperature, making it more prone to fluctuations and causing discomfort for the driver and passengers due to sudden changes in temperature.

[0070] Therefore, some embodiments of the present invention propose a control method for an in-vehicle air conditioner, applicable to vehicles equipped with an in-vehicle air conditioner, such as traditional fuel vehicles, hybrid vehicles, etc., which have an automatic start-stop function. The in-vehicle air conditioner includes air vents and a heating system. The heating system is configured to deliver warm air to the air vents. The heating system includes a temperature damper, which is configured to adjust its opening degree to control the outlet air temperature. That is, in this embodiment, the outlet air temperature can be adjusted by controlling the opening degree of the temperature damper. See details below. Figures 1 to 7 The control method for vehicle air conditioning is explained below.

[0071] Reference Figure 1 As shown in the embodiment of the invention, the heating system includes an engine, a water pump, a heater, and a heater core. The engine is installed in one water circuit, while the water pump, heater, and heater core are installed in another water circuit. A four-way valve is provided between the two water circuits. The water pump drives the water to flow in the water circuit, and the heater core heats the air and delivers it to the air outlet.

[0072] Continue to refer to Figure 1 As shown, when the four-way valve is open, the water circuit where the engine is located can be connected to another water circuit. Based on this, the heat from the engine and the heat generated by the heater can be transferred together to the heater core, meaning the heater and engine work together to heat the heater core. When the four-way valve is closed, the water circuit where the engine is located is isolated from the water circuit where the heater is located. At this time, the heater heats the heater core alone.

[0073] Reference Figure 2 As shown, in this embodiment of the invention, the control method for a vehicle air conditioner includes:

[0074] Step S101: When the vehicle is started, the initial ambient temperature outside the vehicle and the initial thermal load of the vehicle are obtained.

[0075] In this embodiment of the invention, when the vehicle starts (i.e., at the moment of engine ignition), the system automatically initiates an environmental assessment process, automatically acquiring the initial ambient temperature and initial heat load, thereby achieving an assessment of environmental conditions upon vehicle startup. In one example, multiple sensors are distributed inside and outside the vehicle body, including but not limited to sensors for detecting the outside temperature, sensors for detecting the inside temperature of the passenger compartment, and sensors for detecting sunlight intensity. In another example, the vehicle's heat load can be calculated by combining the passenger compartment temperature, outside ambient temperature, and sunlight intensity acquired by the sensors with the user-set temperature.

[0076] Step S102: Obtain the first current ambient temperature of the external environment and the basic value of the opening of the temperature damper.

[0077] In this embodiment of the invention, after the vehicle has been started and running for a period of time, the system can obtain the first current ambient temperature outside the vehicle at the current moment. It is understood that, considering the dynamic changes in environmental conditions, the ambient temperature may change after a period of time. Therefore, re-detecting the ambient temperature can not only determine the current temperature conditions, but also be used to compare it with the initial ambient temperature, thereby assessing the trend of ambient temperature change.

[0078] In this embodiment of the invention, to initially set the control benchmark for the temperature damper, the system first calculates the target heat source temperature required by the warm air core based on the initial heat load and initial ambient temperature, without considering the potential impact of additional negative factors on the outlet air temperature. Then, by combining the user-set temperature and the selected outlet air mode, the basic opening value of the temperature damper can be calculated. This basic opening value represents the initial degree of opening of the temperature damper required to achieve the user's desired outlet air temperature, without considering the influence of negative environmental conditions.

[0079] Step S103: When the initial ambient temperature is not within the preset first temperature range and the first current ambient temperature is less than or equal to the minimum value of the first temperature range, obtain the current heat load of the vehicle.

[0080] In this embodiment of the invention, the first temperature range is a temperature range that does not significantly affect the heating performance of the heating system. That is, within this ambient temperature range, the vehicle's outlet air temperature exhibits high stability and minimal fluctuation. Therefore, when the initial ambient temperature is not within the first temperature range and the current ambient temperature is less than or equal to the minimum value of the first temperature range, it indicates that the initial ambient temperature has already adversely affected the outlet air temperature, and the current ambient temperature has not recovered, meaning the adverse conditions persist. Based on this, to reduce the fluctuation of the outlet air temperature, temperature compensation measures are needed.

[0081] Step S104: When the initial heat load is not within the preset load range and the current heat load is greater than or equal to the maximum value of the load range, the opening compensation value of the temperature damper is obtained based on the current heat load and the first current ambient temperature.

[0082] In this embodiment of the invention, the load range refers to the load area that does not significantly affect the heating performance of the heating system. That is, under this heat load condition, the outlet air temperature of the vehicle exhibits high stability and minimal fluctuation. Therefore, when the initial heat load is not within the load range and the current heat load is greater than or equal to the maximum value of the load range, it indicates that the initial heat load has already adversely affected the outlet air temperature, and the current heat load has not decreased, meaning the adverse conditions continue. Based on this, in order to reduce the fluctuation of the outlet air temperature, temperature compensation measures are needed.

[0083] It is understood that the embodiments of the present invention comprehensively consider the adverse effects of ambient temperature and vehicle heat load on the heating system, thereby improving the accuracy of operating condition assessment. In this embodiment, when both ambient temperature and heat load adversely affect the heating system, the opening compensation value of the temperature damper is obtained based on the current heat load and the first current ambient temperature. In one example, the opening compensation value can be obtained by looking up a table. (Refer to...) Figure 3 As shown, in one example, the current heat load is 55 degrees Celsius, the first current ambient temperature is -15 degrees Celsius, and the opening compensation value is 70% according to the table. It should be noted that... Figure 3 The lookup tables in the database are derived in advance through experimental calculations and testing to ensure the accuracy and reliability of the data.

[0084] Step S105: Detect the second current ambient temperature of the external environment at preset time intervals.

[0085] In this embodiment of the invention, after obtaining the first current ambient temperature, the temperature of the external environment is detected again after a preset time interval to obtain the latest temperature, i.e., to obtain the second current ambient temperature, ensuring continuous tracking and response to changes in the external environment. It should be noted that the preset time can be set to 0 seconds or an extremely short time, such as 0.01 seconds; this embodiment does not limit this.

[0086] Step S106: When the first current ambient temperature is within the preset second temperature range, or when the first current ambient temperature is not within the second temperature range and the second current ambient temperature is less than or equal to the minimum value of the second temperature range, detect and record the engine downtime of the vehicle.

[0087] In this embodiment of the invention, the second temperature range is a temperature range that is lower than the first temperature range. Specifically, the maximum value of the second temperature range is less than the minimum value of the first temperature range. For example, the first temperature range is -5 degrees to 0 degrees, and the second temperature range is -15 degrees to -12 degrees.

[0088] In this embodiment, when the first current ambient temperature is within a preset second temperature range, it indicates that the previous ambient temperature detection occurred in a relatively harsh temperature environment. When the first current ambient temperature is not within the second temperature range and the second current ambient temperature is less than or equal to the minimum value of the second temperature range, it indicates that the previous ambient temperature detection occurred in a relatively good temperature environment, while the current ambient temperature detection occurs in a harsh temperature environment, meaning that the ambient temperature conditions have further deteriorated. Based on this, this embodiment further detects the engine's operating status to determine the degree of temperature compensation measures.

[0089] Step S107: When the shutdown duration is greater than or equal to the preset duration threshold, obtain the preset opening protection value of the temperature damper.

[0090] In this embodiment of the invention, when the downtime is greater than or equal to a preset time threshold, it indicates that the heat output from the engine as one of the heat sources is very limited, and further temperature compensation is needed, i.e., obtaining an opening protection value. The purpose of setting the opening protection value is to ensure sufficient temperature compensation for the outlet air temperature by increasing the opening of the temperature damper under harsh environmental conditions and when the heat source is insufficient. In this embodiment, the opening protection value is a calibration value; for example, the opening protection value is 90%.

[0091] Step S108: Control the opening of the temperature damper based on the basic opening value, the compensation opening value, and the protection opening value.

[0092] In this embodiment of the invention, the basic opening value, the compensation opening value, and the protection opening value can be compared, and the opening of the temperature damper can be controlled based on the comparison result.

[0093] Reference Figure 4 As shown, in one example, step S108 includes:

[0094] Step S1081: Compare the basic opening value, the compensation value, and the protection value, and take the largest one among them as the execution value.

[0095] Step S1082: Control the opening of the temperature damper according to the opening execution value.

[0096] In this embodiment of the invention, the largest value among the basic opening value, the compensation opening value, and the protection opening value is used as the control basis to control the opening of the temperature damper, thereby ensuring sufficient heat output and enabling the air temperature to be raised to the user's desired temperature.

[0097] This invention acquires the initial ambient temperature and initial heat load of the vehicle when it starts, and then acquires parameters such as the first current ambient temperature, the second current ambient temperature, and the current heat load. This allows for real-time sensing of changes in external environmental conditions. By comprehensively considering the impact of engine operating status changes and environmental condition changes on the heating system, and using the current heat load and the first current ambient temperature, a temperature damper opening compensation value is obtained. Based on the acquired opening base value, opening compensation value, and preset opening protection value, the opening of the temperature damper is controlled. This enables automatic adjustment of the temperature damper opening as operating conditions change, ensuring that the heating system provides a stable outlet air temperature under different environmental conditions. This effectively reduces outlet air temperature fluctuations caused by environmental changes and engine operating status changes, making the temperature inside the vehicle more stable and reducing the possibility of passengers experiencing sudden temperature changes, thus significantly improving the driving and riding experience.

[0098] In this embodiment of the invention, step S1081 includes:

[0099] Step S109: When the initial ambient temperature, the first current ambient temperature, the initial heat load, and the current heat load meet the preset first condition, compare the opening base value and the opening protection value, and take the largest one of the opening base value and the opening protection value as the opening execution value.

[0100] The first condition includes: the initial ambient temperature is within a first temperature range; or, the initial ambient temperature is not within the first temperature range and the first current ambient temperature is greater than or equal to the maximum value of the first temperature range; or, the initial heat load is within a load range; or, the initial heat load is not within a load range and the current heat load is less than or equal to the minimum value of the load range.

[0101] It is understood that in this embodiment of the invention, when the initial ambient temperature, the first current ambient temperature, the initial heat load, and the current heat load meet the preset first condition, it means that the ambient temperature and heat load have little negative impact on the heating system, and only the engine's operating status needs to be considered. Therefore, in this embodiment, only the largest value among the opening base value and the opening protection value needs to be used as the control basis.

[0102] In this embodiment of the invention, step S1081 includes:

[0103] Step S110: When the first current ambient temperature, the second current ambient temperature and the downtime meet the preset second condition, compare the opening base value and the opening compensation value, and take the largest one of the opening base value and the opening compensation value as the opening execution value.

[0104] The second condition includes: the first current ambient temperature is not within the second temperature range and the second current ambient temperature is greater than or equal to the minimum value of the second temperature range; or, the downtime is less than the duration threshold.

[0105] It is understood that in this embodiment of the invention, when the first current ambient temperature, the second current ambient temperature and the downtime meet the preset second condition, it means that the engine's operating status has little negative impact on the heating system. Only the impact of ambient temperature and heat load on the heating system needs to be considered. Therefore, in this embodiment, only the largest value among the opening base value and the opening compensation value needs to be used as the control basis.

[0106] In one example, the temperature compensation strategy for the impact of ambient temperature and heat load on the heating system is defined as Compensation Strategy One, which obtains the opening compensation value; the temperature compensation strategy for the impact of engine operating conditions on the heating system is defined as Compensation Strategy Two, which obtains the opening protection value. The first temperature range is -5 degrees to 0 degrees, the second temperature range is -15 degrees to -12 degrees, the load range is 40 degrees to 45 degrees, the duration threshold is 1 minute, and the basic opening value is 50%.

[0107] Based on this, when the detected initial ambient temperature is -3℃ and the initial heat load is 42 degrees, if the external ambient temperature drops to -5 degrees and the heat load rises to 50 degrees, that is, the first current ambient temperature is -5 degrees and the current heat load is 5 degrees, then compensation strategy one is executed.

[0108] When the first current ambient temperature is -13 degrees Celsius and the engine shutdown time exceeds 1 minute, compensation strategy two is executed. When the first current ambient temperature is -5 degrees Celsius, the second current ambient temperature is -18 degrees Celsius, and the engine shutdown time exceeds 1 minute, compensation strategy two is executed.

[0109] Understandably, when starting a vehicle in cold conditions, the engine coolant temperature is initially low. If the engine's coolant circuit is connected to the heater's coolant circuit, the engine will increase the burden on the heater to supply heat to the heater core. This means the heater needs to distribute heat to simultaneously raise the engine temperature and the heater core temperature, resulting in a slower rise in the air outlet temperature.

[0110] Therefore, referring to Figure 5 As shown, in this embodiment of the invention, the control method for vehicle air conditioning further includes:

[0111] Step S201: When the vehicle is started, obtain the initial coolant temperature and initial speed of the engine.

[0112] Step S202: Obtain the current coolant temperature and current engine speed of the engine.

[0113] In this embodiment of the invention, the engine is equipped with a temperature sensor and a speed sensor. When the vehicle is started, the initial water temperature and initial speed are acquired. After the engine has been running for a period of time, the current water temperature and current speed are acquired, thereby assessing the changes in the engine's operating status.

[0114] Step S203: When the initial water temperature is not within the third temperature range and the current water temperature is greater than or equal to the maximum value of the third temperature range, acquire environmental data and the user-set desired temperature, and control the heater and engine to supply heat to the heater core according to the environmental data and desired temperature.

[0115] In this embodiment of the invention, the third temperature range is the range of water temperature within which the engine puts a burden on the heater. That is, when the engine water temperature is within this range, the heater needs to allocate heat to raise the engine temperature. Therefore, when the initial water temperature is not within the third temperature range and the current water temperature is greater than or equal to the maximum value of the third temperature range, it indicates that the engine water temperature is high when the vehicle starts, and it does not put a burden on the heater. Furthermore, if the engine water temperature continues to rise to a high temperature, the heater does not need to allocate heat to raise the engine temperature. Therefore, no temperature compensation measures are required. At this time, the heater can be controlled to cooperate with the engine to supply heat to the heater core based on environmental data and the desired temperature. It should be noted that environmental data includes parameters such as the vehicle interior temperature, the vehicle exterior temperature, and sunlight intensity; this embodiment does not limit these parameters.

[0116] Step S204: When the initial water temperature is within the third temperature range, or when the initial water temperature is not within the third temperature range and the current water temperature is less than or equal to the minimum value of the third temperature range, obtain the current engine speed.

[0117] In this embodiment of the invention, when the initial coolant temperature is within the third temperature range, it indicates that the engine coolant temperature is low when the vehicle starts, placing a burden on the heater. When the initial coolant temperature is not within the third temperature range and the current coolant temperature is less than or equal to the minimum value of the third temperature range, it indicates that the engine coolant temperature is not low when the vehicle starts, and there is no burden on the heater. However, at this time, the engine coolant temperature drops to a lower temperature, placing a burden on the heater. Based on this, this embodiment needs to further detect the engine speed. In one example, the third temperature range is 30 degrees to 40 degrees.

[0118] Step S205: When the initial speed is within the preset speed range, or when the initial speed is not within the speed range and the current speed is less than or equal to the minimum value of the speed range, control the heater to supply heat to the warm air core separately.

[0119] In this embodiment of the invention, the speed range refers to the range of speeds within which the engine does not generate sufficient heat. Therefore, when the initial speed is within the preset speed range, it indicates that the vehicle starts at a low speed, making it difficult to generate enough heat. When the initial speed is not within the speed range and the current speed is less than or equal to the minimum value of the speed range, it indicates that the vehicle starts at a relatively high speed, but the speed drops to a low level, making it difficult to generate enough heat. Therefore, in both of these situations, the engine puts a burden on the heater. Thus, it is necessary to close the four-way valve to control the heater to supply heat only to the heater core, thereby avoiding the heater distributing heat to both the engine temperature and the heater core temperature simultaneously, which would result in a slow rise in the outlet air temperature.

[0120] Step S206: When the initial speed is not within the speed range and the current speed is greater than or equal to the maximum value of the speed range, acquire the environmental data and the user-set desired temperature, and control the heater to cooperate with the engine to supply heat to the heater core according to the environmental data and desired temperature.

[0121] In this embodiment of the invention, when the initial speed is not within the speed range and the current speed is greater than or equal to the maximum value of the speed range, it indicates that the vehicle's starting speed is not low. At this time, the vehicle speed also rises to a relatively high speed, and the engine can generate sufficient heat without burdening the heater. Based on this, no temperature compensation measures are needed. In this case, the heater can be controlled to cooperate with the engine to supply heat to the heater core based on environmental data and the desired temperature.

[0122] Understandably, vehicles equipped with automatic start-stop functionality will temporarily shut off the engine to save fuel when the activation conditions are met. However, the temporary shutdown of the engine reduces the heat source, preventing the heater core from receiving enough heat to heat the air, which in turn causes fluctuations in the outlet air temperature.

[0123] Therefore, referring to Figure 6 As shown, in this embodiment of the invention, the control method for vehicle air conditioning further includes:

[0124] Step S301: When the vehicle is started, obtain the initial coolant temperature of the engine.

[0125] Step S302: When the initial ambient temperature is within the preset fourth temperature range, or when the initial ambient temperature is not within the fourth temperature range and the first current ambient temperature is less than or equal to the minimum value of the fourth temperature range, obtain the current water temperature of the engine and the target temperature of the heater core.

[0126] In this embodiment of the invention, the fourth temperature range is the range of ambient temperatures within which a temporary engine shutdown would affect the heater's ability to provide sufficient heat to the heater core. Therefore, when the initial ambient temperature is within the preset fourth temperature range, it indicates that the ambient temperature is low when the vehicle starts, and the heater cannot provide sufficient heat to the heater core alone. When the initial ambient temperature is not within the fourth temperature range and the first current ambient temperature is less than or equal to the minimum value of the fourth temperature range, it indicates that the ambient temperature is not low when the vehicle starts; however, the ambient temperature has dropped significantly, and the heater cannot provide sufficient heat to the heater core alone. In both of these cases, this embodiment requires further evaluation of the engine's operating status to determine whether additional heat from the engine is needed.

[0127] Step S303: When the difference between the initial water temperature and the target temperature is within a preset difference range, or when the difference between the initial water temperature and the target temperature is not within the difference range and the difference between the current water temperature and the target temperature is less than or equal to the maximum value of the difference range, a start request is sent to keep the engine running.

[0128] In this embodiment of the invention, when the difference between the initial coolant temperature and the target temperature is within a preset range, it indicates that the engine coolant temperature is high enough to provide additional heat to the heater core when the vehicle starts. When the difference between the initial coolant temperature and the target temperature is not within the range and the difference between the current coolant temperature and the target temperature is less than or equal to the maximum value of the range, it indicates that the engine coolant temperature is not high when the vehicle starts; however, the engine coolant temperature has already been heated to a level sufficient to provide additional heat to the heater core. In both of these cases, the system can send a start request to keep the engine running, thereby cooperating with the heater to provide heat to the heater core.

[0129] It should be noted that in this embodiment, the system only sends a start request. Whether or not to start the engine still requires a detailed evaluation of other conditions of the automatic start-stop function before a decision is made on whether to start the engine.
