Description

Technical Field

[0001] This application relates to the field of vehicle air conditioning, and more specifically, to a vehicle air conditioning system control method, device, electronic equipment, and storage medium. Background Technology

[0002] Currently, when users turn on the air conditioning in their vehicles, it remains on until the vehicle is turned off, at which point it automatically shuts off. Some users proactively turn off the air conditioning's cooling or heating function in advance when they anticipate reaching their destination to save energy. However, relying solely on personal experience makes it difficult to achieve optimal results; moreover, not all users remember to perform this operation for every trip, and not all users are aware of this energy-saving principle. Furthermore, if the vehicle's air conditioning remains on until the final moment of shutdown, the passenger compartment remains in a highly comfortable state. A significant amount of energy is stored within the passenger compartment and the air conditioning system pipes, especially when there is a large temperature difference between the inside and outside of the vehicle. If the occupants lock the car and leave immediately, this energy will be completely wasted. Additionally, if the air conditioning is turned off immediately while cooling, the condensate on the evaporator cannot evaporate. This condensate, remaining for an extended period, allows microorganisms to multiply, and pollutants and microbial metabolites adhere to the fin surface, forming a layer of odor that is difficult to remove. The next time the air conditioning is turned on, the odor will permeate the vehicle's interior. Summary of the Invention

[0003] The purpose of this application is to provide a vehicle air conditioning system control method, device, electronic device and storage medium to turn off the vehicle air conditioning system in advance before the end of the vehicle trip, thereby avoiding various adverse consequences caused by the vehicle air conditioning system failing to turn off automatically in advance.

[0004] In a first aspect, the present invention provides a method for controlling an in-vehicle air conditioning system, the method comprising: The system obtains the travel time of the target vehicle and the operating status of the vehicle's air conditioning system, and determines the remaining travel time of the target vehicle. When the operating status of the vehicle air conditioning system indicates that the vehicle air conditioning system is in the on state, it is determined whether the driving time of the target vehicle is greater than or equal to a first time threshold. When the driving time of the target vehicle is greater than or equal to the first time threshold, the vehicle air conditioning system is controlled to operate in a low-power state in advance based on the remaining driving time of the target vehicle, or the cooling and heating functions of the vehicle air conditioning system are turned off in advance.

[0005] The method of this application can determine whether the driving time of the target vehicle is greater than or equal to a first time threshold when the vehicle's air conditioning system is in an on state. If the driving time is greater than or equal to the first time threshold, the method can preemptively control the vehicle's air conditioning system to a low-power state or preemptively shut down its cooling and heating functions based on the remaining driving time. This prevents the vehicle's air conditioning system from generating excess energy that cannot be used after the trip ends, thus avoiding energy waste caused by the system stopping abruptly at the end of the journey. Furthermore, it avoids the need to manually turn off the air conditioning.

[0006] In an optional implementation, the vehicle's air conditioning system is pre-controlled to operate in a low-power state based on the remaining driving time of the target vehicle, or the cooling and heating functions of the vehicle's air conditioning system are pre-controlled to be turned off, including: When the remaining driving time of the target vehicle is less than the second time threshold and greater than or equal to the third time threshold, the operating state of the vehicle air conditioning system is controlled to the low power consumption state. When the remaining driving time of the target vehicle is less than the third time threshold, the cooling and heating functions of the vehicle's air conditioning system are turned off, wherein the third time threshold is less than the second time threshold.

[0007] This optional implementation can control the vehicle air conditioning system to operate in a low-power state when the remaining driving time of the target vehicle is less than a second time threshold but greater than or equal to a third time threshold; and control the cooling and heating functions of the vehicle air conditioning system to be turned off when the remaining driving time of the target vehicle is less than the third time threshold, thereby achieving a phased and progressive reduction in the energy consumption of the vehicle air conditioning system, thus balancing the user's cooling and heating needs with the energy consumption reduction needs of the vehicle air conditioning system.

[0008] In an optional implementation, determining the remaining travel time of the target vehicle includes: Obtain the operating status of the vehicle's in-vehicle map navigation; When the vehicle navigation system is in operation and the navigation function is being executed, the remaining time calculated by the vehicle navigation system for the navigation destination is determined as the remaining travel time of the target vehicle.

[0009] This optional implementation can determine the remaining travel time of the target vehicle as the remaining travel time calculated by the vehicle map navigation for the navigation destination when the vehicle map navigation is performing navigation function. By utilizing the data of the navigation system, a more accurate remaining travel time of the target vehicle can be obtained.

[0010] In an optional implementation, determining the remaining travel time of the target vehicle includes: Obtain the user's frequently used parking addresses and the current location of the target vehicle, and determine the destination identification range based on the user's frequently used parking addresses; When the current location of the target vehicle falls within the destination identification range, the user's commonly used parking address is determined as the destination of the target vehicle's journey. The remaining travel time of the target vehicle is determined based on its current location and the destination of its journey.

[0011] This optional implementation can obtain the user's frequently used parking addresses and the current location of the target vehicle, and determine the destination identification range based on the user's frequently used parking addresses. Then, when the current location of the target vehicle falls within the destination identification range, the user's frequently used parking address is determined as the destination of the target vehicle's journey. Thus, the remaining travel time of the target vehicle can be determined based on the current location of the target vehicle and the destination of the target vehicle's journey. Finally, the destination can be determined without the travel data calculated by the navigation system, thereby using the destination to determine the remaining travel time of the target vehicle.

[0012] In an optional implementation, determining the remaining travel time of the target vehicle includes: Obtain user's historical driving data; Based on the user's historical driving data, predict the user's trip, and based on the user's trip, predict the total trip time and the confidence level of the total trip time; The remaining travel time of the target vehicle is determined based on the total travel time, the confidence level of the total travel time, and the travel time already traveled by the target vehicle.

[0013] This optional implementation can predict the total trip time and the confidence level of the total trip time based on the user's historical driving data, and determine the remaining driving time of the target vehicle based on the total trip time, the confidence level of the total trip time, and the driving time of the target vehicle.

[0014] In an optional implementation, the step of controlling the operating state of the vehicle air conditioning system to a low-power state in advance based on the remaining driving time of the target vehicle includes: When the vehicle air conditioning system is in cooling mode, the current interior temperature of the target vehicle is obtained, and 3 degrees Celsius is added to the current interior temperature of the target vehicle to obtain a first temperature value. The minimum value between the first temperature value and the second temperature value is taken as the target cooling temperature, wherein the second temperature value is 28 degrees Celsius; The cooling temperature of the vehicle air conditioning system will be controlled to the target cooling temperature.

[0015] This optional implementation can obtain the current interior temperature of the target vehicle when the vehicle air conditioning system is in cooling mode, and add 3 degrees Celsius to the current interior temperature of the target vehicle to obtain a first temperature value. Then, the minimum value between the first temperature value and a second temperature value is taken as the target cooling temperature, wherein the second temperature value is 28 degrees Celsius. This allows the vehicle air conditioning system to be controlled to the target cooling temperature. In this way, while reducing the power consumption required for cooling by increasing the cooling temperature, it can ensure that the upper limit of the cooling temperature is 28 degrees Celsius, thus avoiding excessively high interior temperatures.

[0016] In an optional implementation, the step of controlling the operating state of the vehicle air conditioning system to a low-power state in advance based on the remaining driving time of the target vehicle includes: When the vehicle air conditioning system is in heating mode, the current interior temperature of the target vehicle is obtained, and 5 degrees Celsius is subtracted from the current interior temperature of the target vehicle to obtain the target heating temperature. The cooling temperature of the vehicle air conditioning system will be controlled to the target cooling temperature.

[0017] This optional implementation can obtain the current interior temperature of the target vehicle when the vehicle air conditioning system is in heating mode, and subtract 5 degrees Celsius from the current interior temperature of the target vehicle to obtain the target heating temperature, thereby reducing the power consumption of the vehicle air conditioning system.

[0018] In an optional implementation, the step of controlling the operating state of the vehicle air conditioning system to a low-power state in advance based on the remaining driving time of the target vehicle includes: When the vehicle air conditioning system is in cooling mode, the compressor speed of the vehicle air conditioning system is reduced to control the vehicle air conditioning system to operate in the low power consumption mode.

[0019] This optional implementation can reduce the compressor speed of the vehicle air conditioning system to achieve the low power consumption state, thereby reducing the power consumption of the vehicle air conditioning system even when the cooling temperature cannot be determined.

[0020] In an optional implementation, the step of controlling the operating state of the vehicle air conditioning system to a low-power state in advance based on the remaining driving time of the target vehicle includes: When the vehicle air conditioning system is in heating mode, determine the type of the vehicle air conditioning system; When the vehicle air conditioning system is a heat pump air conditioning system, the heater level is reduced to control the vehicle air conditioning system to the low power consumption state. When the vehicle air conditioning system is a single-cooling air conditioning system, the compressor speed of the vehicle air conditioning system is reduced to control the operating state of the vehicle air conditioning system to the low-power state.

[0021] This optional implementation method can determine the specific way to reduce power consumption based on the type of vehicle air conditioning system, so that when the vehicle air conditioning system is in heating mode, the power consumption reduction method can be flexibly adopted.

[0022] In a second aspect, the present invention provides a vehicle air conditioning system control device, the device comprising: The acquisition module is used to acquire the travel time of the target vehicle and the operating status of the vehicle's air conditioning system, and to determine the remaining travel time of the target vehicle. The judgment module is used to determine whether the driving time of the target vehicle is greater than or equal to a first time threshold when the operating status of the vehicle air conditioning system indicates that the vehicle air conditioning system is in the on state. The control module is used to control the vehicle air conditioning system to operate in a low-power state in advance, or to control the cooling and heating functions of the vehicle air conditioning system to be turned off in advance, based on the remaining driving time of the target vehicle when the driving time of the target vehicle is greater than or equal to the first time threshold.

[0023] The device of this application can determine whether the driving time of the target vehicle is greater than or equal to a first time threshold when the vehicle's air conditioning system is in an on state. If the driving time is greater than or equal to the first time threshold, it can preemptively control the vehicle's air conditioning system to operate in a low-power state based on the remaining driving time, or preemptively shut down the cooling and heating functions of the vehicle's air conditioning system. This prevents the vehicle's air conditioning system from generating excess energy that cannot be used after the journey ends, thus avoiding energy waste caused by the system stopping abruptly at the end of the journey. Furthermore, it also avoids the need to manually turn off the air conditioning.

[0024] Thirdly, the present invention provides an electronic device, comprising: Processor; and The memory is configured to store machine-readable instructions that, when executed by the processor, perform the method as described in any of the foregoing embodiments.

[0025] The electronic device of this application, by executing a vehicle air conditioning system control method, can determine whether the driving time of the target vehicle is greater than or equal to a first time threshold when the vehicle air conditioning system is in an on state. If the driving time of the target vehicle is greater than or equal to the first time threshold, it can preemptively control the vehicle air conditioning system to a low-power state based on the remaining driving time of the target vehicle, or preemptively control the cooling and heating functions of the vehicle air conditioning system to be turned off. This avoids the vehicle air conditioning system generating excess energy that cannot be used after the trip ends, thus preventing the vehicle air conditioning system from shutting down directly at the end of the trip and causing energy waste. Furthermore, it also avoids the need to manually turn off the air conditioning.

[0026] Fourthly, the present invention provides a storage medium storing a computer program, the computer program being executed by a processor as described in any of the foregoing embodiments.

[0027] The storage medium of this application, by executing a vehicle air conditioning system control method, can determine whether the driving time of the target vehicle is greater than or equal to a first time threshold when the vehicle air conditioning system is in an on state. Furthermore, if the driving time of the target vehicle is greater than or equal to the first time threshold, it can preemptively control the vehicle air conditioning system to operate in a low-power state based on the remaining driving time of the target vehicle, or preemptively control the cooling and heating functions of the vehicle air conditioning system to be turned off. This prevents the vehicle air conditioning system from generating excess energy that cannot be used after the trip ends, thus avoiding energy waste caused by the vehicle air conditioning system stopping directly when the trip ends. In addition, it can also avoid the need to manually turn off the air conditioning. Attached Figure Description

It should be understood that the following drawings only show some embodiments of this application and should not be regarded as a limitation of the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

Detailed Implementation

[0030] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0031] Please see Figure 1 , Figure 1 This is a flowchart illustrating a vehicle air conditioning system control method provided in an embodiment of this application. Figure 1 As shown, the method in this application embodiment includes the following steps: 101. Obtain the travel time of the target vehicle and the operating status of the vehicle's air conditioning system, and determine the remaining travel time of the target vehicle; 102. When the vehicle air conditioning system is in the on state, determine whether the driving time of the target vehicle is greater than or equal to the first time threshold. 103. When the driving time of the target vehicle is greater than or equal to the first time threshold, the vehicle air conditioning system is controlled to operate in a low power consumption state in advance based on the remaining driving time of the target vehicle, or the cooling and heating functions of the vehicle air conditioning system are turned off in advance.

[0032] In this embodiment of the application, the target vehicle refers to a specific vehicle to which the air conditioning control operation is performed, and is the object of the control method. The target vehicle can be a new energy target vehicle or a fuel-powered target vehicle; the new energy target vehicle can be a hybrid vehicle or a pure electric vehicle.

[0033] In this embodiment of the application, the travel time can refer to the cumulative travel time of the target vehicle from the start time to the current time.

[0034] In this embodiment of the application, the vehicle air conditioning system refers to a system installed inside a vehicle that has functions such as cooling, heating, and ventilation. The vehicle air conditioning system can be a heat pump type vehicle air conditioning system or a single-cooling type vehicle air conditioning system.

[0035] In this embodiment, the operating status of the vehicle air conditioning system refers to the current working mode and parameter configuration of the vehicle air conditioning system. The operating status of the vehicle air conditioning system can be either cooling or heating.

[0036] In this embodiment, the remaining driving time of the target vehicle refers to the estimated driving time required for the target vehicle to reach its destination from the current moment. This remaining driving time can be the remaining driving time planned by the navigation system or the remaining driving time predicted from historical data.

[0037] In this embodiment, the first time threshold refers to the critical value of the driving time at which air conditioning energy consumption control should be activated. This first time threshold can be determined based on road condition type. For example, if the target vehicle is driving in urban conditions, the first time threshold is the urban road condition first time threshold; if the target vehicle is driving on a highway, the first time threshold is the highway road condition first time threshold. It should be noted that the reason for only implementing air conditioning energy consumption control when the time exceeds the first time threshold is to avoid implementing air conditioning energy consumption control immediately after the vehicle starts, for example, to avoid controlling the air conditioning to turn off immediately after the vehicle starts.

[0038] In this embodiment, a low-power state refers to the operating state of the vehicle air conditioning system that maintains basic functions with low energy consumption. This low-power state can be either a cooling low-power state or a heating low-power state.

[0039] In this embodiment, the cooling and heating function refers to the core function of the vehicle air conditioning system to lower or raise the temperature inside the vehicle.

[0040] In this embodiment of the application, a specific method for obtaining the elapsed driving time and air conditioning operating status of the target vehicle to determine the remaining driving time is as follows: The system reads the cumulative running time since the vehicle started by the vehicle's ECU (Electronic Control Unit), obtains the operating status through feedback signals from the air conditioning control system, and calculates the remaining driving time based on navigation data.

[0041] In this embodiment of the application, when the air conditioner is turned on, a specific way to determine whether the driving time is greater than or equal to the first time threshold is to convert the driving time obtained by the ECU into a standard time format and compare it with the preset stored first time threshold.

[0042] The method in this application embodiment can determine whether the driving time of the target vehicle is greater than or equal to a first time threshold when the vehicle's air conditioning system is in an on state. If the driving time is greater than or equal to the first time threshold, the method can control the vehicle's air conditioning system to operate in a low-power state or to shut down its cooling and heating functions in advance based on the remaining driving time. This prevents the vehicle's air conditioning system from generating excess energy that cannot be used after the trip ends, thus avoiding energy waste caused by the system stopping abruptly at the end of the trip. Furthermore, it avoids the need to manually turn off the air conditioning. For example, when the vehicle is nearing its destination, the air conditioning switches to a low-power state in advance, preventing it from running at high power after arrival and reducing unnecessary energy consumption. Another example is that, compared to turning off the air conditioning directly at the end of the trip, this gradual adjustment method prevents sudden and drastic changes in the vehicle's interior temperature, ensuring a comfortable experience for the user before exiting the vehicle. Finally, when the vehicle arrives at its destination, the air conditioning system is already off, eliminating the need for the user to manually turn it off.

[0043] In this embodiment of the application, as an optional implementation, the vehicle air conditioning system is controlled to operate in a low-power state in advance based on the remaining driving time of the target vehicle, or the cooling and heating functions of the vehicle air conditioning system are turned off in advance, including the following sub-steps: When the remaining driving time of the target vehicle is less than the second time threshold and greater than or equal to the third time threshold, the vehicle air conditioning system is controlled to operate in a low-power state. If the remaining driving time of the target vehicle is less than a third time threshold, the cooling and heating functions of the vehicle's air conditioning system will be turned off. The third time threshold is less than the second time threshold.

[0044] In the above implementation, the second time threshold refers to the critical value of the remaining driving time used to divide the low-power control phase, which is greater than the third time threshold. The second time threshold can be determined according to the season; for example, in summer, the second time threshold is the summer cooling second time threshold, while in winter, the second time threshold can be the winter heating second time threshold.

[0045] In the above implementation, the third time threshold is the critical value of the remaining driving time used to trigger the cooling and heating function to be turned off, which is less than the second time threshold.

[0046] In the above implementation, since the second time threshold is greater than the first time threshold, the reduction in air conditioning power consumption can only be triggered after the vehicle has been driven for a period of time. This avoids triggering the power reduction at the beginning of the vehicle's operation, thus ensuring the cooling and heating effect in the cabin beforehand. In other words, it prevents the power reduction function from being triggered too early, which could cause the cooling and heating effect in the cabin to fall short of expectations. Furthermore, since the second time is less than the third time threshold, the power consumption can be reduced before the air conditioning system is turned off, rather than being turned off directly. This avoids excessive changes in the cooling and heating effect in the vehicle caused by directly turning off the air conditioning system, which could affect the comfort of the users in the cabin.

[0047] In the above implementation, a specific way to determine whether the remaining driving time is less than the second time threshold and greater than or equal to the third time threshold is to perform interval matching between the remaining time updated in real time by the navigation system and the preset second and third time thresholds.

[0048] In the above implementation, a specific way to determine whether the remaining travel time is less than the second time threshold and greater than or equal to the third time threshold is as follows: the remaining time predicted based on historical travel data is dynamically corrected in combination with the current road conditions and then compared with the threshold.

[0049] This optional implementation can control the vehicle's air conditioning system to operate in a low-power state when the remaining driving time of the target vehicle is less than a second time threshold but greater than or equal to a third time threshold; and control the cooling and heating functions of the vehicle's air conditioning system to be turned off when the remaining driving time of the target vehicle is less than the third time threshold. This achieves a phased and progressive reduction in the energy consumption of the vehicle's air conditioning system, thereby balancing the user's cooling and heating needs with the energy consumption reduction requirements of the vehicle's air conditioning system. For example, when the vehicle has a long remaining driving time, the air conditioning maintains low-power operation, which can meet the user's basic needs for the temperature inside the vehicle without wasting energy. As another example, when the vehicle is about to reach its destination, the cooling and heating functions are directly turned off, avoiding unnecessary energy consumption in a short period of time, and because the remaining time is extremely short, the user will not experience significant temperature discomfort.

[0050] In this application embodiment, as an optional implementation method, determining the remaining driving time of the target vehicle includes the following steps: Obtain the operating status of the vehicle's in-vehicle map navigation; When the vehicle navigation system is performing navigation, the remaining time calculated by the vehicle navigation system for the navigation destination is determined as the remaining travel time of the target vehicle.

[0051] In the above embodiments, the in-vehicle map navigation can be a map navigation application integrated into the vehicle's central control system, or it can be a map navigation application executed by an external system, such as a map navigation application executed by a mobile device. Furthermore, the map navigation application has route planning and real-time navigation functions. Furthermore, the map navigation application can be an online in-vehicle map navigation system or an offline in-vehicle map navigation system.

[0052] In the above implementation, the navigation destination refers to the travel destination set by the user in the vehicle's map navigation.

[0053] In the above implementation, one specific way to obtain the running status of the vehicle navigation map can be: querying the vehicle system API to see if the navigation application is running in the foreground and if there is valid route planning data.

[0054] In the above embodiments, one specific way to obtain the operating status of the vehicle navigation system can be: detecting whether there is real-time location, path and other navigation-related data sent by the navigation system in the vehicle bus.

[0055] In the above implementation, when navigation is in progress, a specific way to determine the remaining time calculated by navigation as the remaining driving time of the target vehicle is to directly read the remaining driving time displayed on the navigation application interface and synchronize it to the air conditioning control module.

[0056] In the above implementation, a specific way to determine the remaining time calculated by navigation as the remaining driving time of the target vehicle is to receive the remaining time parameter pushed by the navigation system through the data interface, and use it as the control basis after format conversion.

[0057] This optional implementation allows the remaining time calculated by the in-vehicle map navigation system for the navigation destination to be determined as the remaining travel time of the target vehicle while the system is performing navigation. By utilizing data from the navigation system, a more accurate remaining travel time can be obtained. For example, when a user uses in-vehicle navigation to travel to an unfamiliar location, the system does not need to perform additional calculations and can directly obtain the accurate remaining time, making air conditioning control more precise. Furthermore, if traffic conditions change during navigation (such as congestion), the remaining time is updated in real time, and the air conditioning control strategy is dynamically adjusted accordingly, avoiding energy waste or a decline in user experience due to changes in traffic conditions.

[0058] In this application embodiment, as an optional implementation method, determining the remaining driving time of the target vehicle includes the following steps: Obtain the user's frequently used parking addresses and the current location of the target vehicle, and determine the destination identification range based on the user's frequently used parking addresses; When the target vehicle's current location falls within the destination identification range, the user's frequently used parking address will be determined as the destination of the target vehicle's journey. The remaining travel time of the target vehicle is determined based on its current location and the destination of its journey.

[0059] In the above implementation, the frequently used parking address refers to a fixed location where the user parks frequently on a daily basis, which is statistically analyzed by the system or manually set by the user. This frequently used parking address can be a home parking address or a work parking address.

[0060] In the above implementation, the destination identification range refers to a geographical area centered on the frequently used parking address, used to determine whether a vehicle is near its destination. This destination identification range can be a destination identification range along urban roads or within a park. If determined numerically, a circular area 5 kilometers away from the frequently used parking address can be used as the destination identification range.

[0061] In the above implementation, the three most frequently occurring parking addresses can be selected from the parking addresses recorded by the vehicle's infotainment system over the past three months as commonly used parking addresses.

[0062] In the above implementation, the system can automatically set circular recognition ranges of different radii based on the area (city / suburb) where commonly used parking addresses are located.

[0063] In the above implementation, users can manually adjust the size of the recognition range corresponding to each commonly used parking address.

[0064] In the above implementation, when the current location falls within the recognition range, the commonly used parking address is determined as the destination of the trip and the remaining travel time is calculated.

[0065] This optional implementation can obtain the user's frequently used parking addresses and the current location of the target vehicle, and determine the destination identification range based on the user's frequently used parking addresses. Therefore, when the target vehicle's current location falls within the destination identification range, the user's frequently used parking address is determined as the destination of the target vehicle's journey. This allows for the determination of the target vehicle's remaining travel time based on its current location and destination. Ultimately, it can determine the destination without the trip data calculated by the navigation system, thus using the destination to determine the remaining travel time. In one example, when a user drives near their home to a frequently used parking lot without navigation enabled, the system automatically identifies the destination and calculates the remaining time, adjusting the air conditioning accordingly without requiring additional user intervention. In another example, for fixed journeys such as daily commutes, the method based on frequently used parking addresses offers high accuracy, and the air conditioning control is more tailored to the user's travel habits, balancing energy saving and comfort.

[0066] In this application embodiment, as an optional implementation method, determining the remaining driving time of the target vehicle includes the following steps: Obtain user's historical driving data; Predict user trips based on historical driving data, and predict the total trip time and confidence level based on user trips; The remaining travel time of the target vehicle is determined based on the total travel time, the confidence level of the total travel time, and the travel time already traveled by the target vehicle.

[0067] In the above implementation, user historical driving data refers to the set of trip-related data generated by the user's past driving. Specifically, based on date type, user historical driving data can be either weekday historical driving data or holiday historical driving data.

[0068] In the above implementation, the total travel time refers to the predicted total duration of the entire journey from departure to destination. The total travel time can be the total travel time under congested conditions or the total travel time under smooth traffic conditions.

[0069] In the above embodiments, confidence level is a quantitative indicator characterizing the reliability of the total travel time prediction result. This confidence level can be either a high-confidence total travel time or a low-confidence total travel time.

[0070] In the above implementation, one specific way to obtain the user's historical driving data is to read the trip records of the past 6 months stored locally in the vehicle, including data such as departure time, departure point, destination, and driving time.

[0071] In the above implementation, one specific way to obtain the user's historical driving data is to synchronize the user's authorized historical driving data through vehicle cloud services and then summarize and organize it.

[0072] In the above implementation, a specific way to predict user trips and determine the total trip time and confidence level based on historical data is as follows: analyze the trip patterns of the same time period and departure point in history through machine learning algorithms to predict the total trip time and confidence level of this trip.

[0073] In the above implementation, a specific way to predict user trips based on historical data and determine the total trip time and confidence level is as follows: statistically analyze the duration distribution of similar historical trips, take the median as the predicted total trip time, and calculate the confidence level based on the data concentration.

[0074] In the above implementation, a specific way to determine the remaining travel time based on the total travel time, confidence level, and travel time is as follows: when the confidence level is higher than a preset threshold, the remaining travel time is obtained by directly subtracting the travel time from the total travel time.

[0075] In the above implementation, a specific way to determine the remaining travel time based on the total travel time, confidence level, and travel time is as follows: when the confidence level is low, the remaining travel time is obtained by combining real-time traffic conditions with the (total travel time - travel time) calculation.

[0076] This optional implementation can predict the total trip time and confidence level of a user's trip based on historical driving data, and determine the remaining travel time of the target vehicle based on the total trip time, the confidence level of the total trip time, and the travel time already traveled by the target vehicle. In one example, if a user departs from home during a fixed time period (such as weekday morning rush hour), the system accurately predicts the total trip time based on historical data, and can reasonably control air conditioning energy consumption even without navigation. In another example, for predictions with low confidence, the remaining time is corrected by combining real-time traffic conditions, avoiding inappropriate air conditioning control timing due to prediction errors and ensuring a good user experience.

[0077] In this embodiment of the application, as an optional implementation, the vehicle air conditioning system is controlled to operate in a low-power state in advance based on the remaining driving time of the target vehicle, including the following sub-steps: When the vehicle's air conditioning system is in cooling mode, the current interior temperature of the target vehicle is obtained, and 3 degrees Celsius is added to the current interior temperature of the target vehicle to obtain the first temperature value. The minimum value between the first temperature value and the second temperature value is taken as the target cooling temperature, where the second temperature value is 28 degrees Celsius; The target cooling temperature is set to the temperature of the vehicle's air conditioning system.

[0078] In the above embodiments, the current temperature inside the vehicle refers to the actual temperature inside the vehicle, which is collected by a temperature sensor. The current temperature inside the vehicle may include the current temperature of the front row and the current temperature of the rear row.

[0079] In the above implementation, the first temperature value refers to the temperature parameter obtained by adding a fixed value to the current temperature inside the vehicle, and is used for low-power control in cooling mode. The first temperature value can be either the summer first temperature value or the spring / autumn first temperature value.

[0080] In the above implementation, the target cooling temperature refers to the set temperature of the air conditioner's cooling function in low-power mode.

[0081] In the above embodiments, when the air conditioner is in cooling mode, one specific way to obtain the current temperature inside the vehicle is to collect data through multiple temperature sensors inside the vehicle and take the average value as the current temperature inside the vehicle.

[0082] In the above embodiments, when the air conditioner is in cooling mode, one specific way to obtain the current temperature inside the vehicle can be: reading the temperature near the driver's seat monitored in real time by the air conditioning control system as the current temperature inside the vehicle. This optional embodiment can obtain the current temperature inside the target vehicle when the vehicle's air conditioning system is in cooling mode, add 3 degrees Celsius to the current temperature inside the target vehicle to obtain a first temperature value, and then take the minimum value between the first temperature value and a second temperature value as the target cooling temperature, where the second temperature value is 28 degrees Celsius. This allows the vehicle's air conditioning system to be controlled at the target cooling temperature. In this way, while reducing the power consumption required for cooling by increasing the cooling temperature, it can ensure that the upper limit of the cooling temperature is 28 degrees Celsius, avoiding excessively high temperatures inside the vehicle. In one example, when the original temperature inside the vehicle is low, the adjusted target cooling temperature is slightly increased, which reduces the power consumption of the air conditioning system without making the user feel stuffy. In another example, the limitation of the second temperature value avoids excessively high temperatures inside the vehicle. Even if the current temperature is low, it can ensure that the adjusted temperature is within a comfortable range, balancing energy saving and user experience.

[0083] In this embodiment of the application, as an optional implementation, the vehicle air conditioning system is controlled to operate in a low-power state in advance based on the remaining driving time of the target vehicle, including the following steps: When the vehicle's air conditioning system is in heating mode, obtain the current interior temperature of the target vehicle and subtract 5 degrees Celsius from the current interior temperature of the target vehicle to obtain the target heating temperature. The target cooling temperature is set to the temperature of the vehicle's air conditioning system.

[0084] This optional implementation can obtain the current interior temperature of the target vehicle when the vehicle's air conditioning system is in heating mode, and then subtract 5 degrees Celsius from the current interior temperature to obtain the target heating temperature, thereby reducing the power consumption of the vehicle's air conditioning system. In one example, the interior was originally warm; the adjusted target heating temperature is slightly lower, reducing the air conditioning's heating power consumption and preventing energy waste.

[0085] In this embodiment of the application, as an optional implementation, the vehicle air conditioning system is controlled to operate in a low-power state in advance based on the remaining driving time of the target vehicle, including the following steps: When the vehicle air conditioning system is in cooling mode, the compressor speed of the vehicle air conditioning system is reduced to control the vehicle air conditioning system to operate in a low-power mode.

[0086] In the above embodiments, compressor speed refers to the operating speed of the compressor in the vehicle air conditioning refrigeration system.

[0087] In the above embodiments, when the air conditioner is in cooling mode, one specific way to obtain the current speed of the compressor is to collect the current speed data in real time through the compressor speed sensor and feed it back to the air conditioner controller.

[0088] In the above embodiments, when the air conditioner is in cooling mode, one specific way to obtain the current speed of the compressor is to read the drive signal sent to the compressor by the air conditioner control system and parse it to obtain the current speed.

[0089] In the above implementation, one specific way to reduce the compressor speed and put the air conditioner into a low-power state is as follows: the air conditioner controller sends a speed reduction command to reduce the compressor speed to the low-power range by a fixed ratio.

[0090] In the above implementation, a specific way to reduce the compressor speed and put the air conditioner into a low-power state is to dynamically adjust the compressor speed according to the difference between the interior temperature and the target temperature, so as to ensure temperature stability while reducing power consumption.

[0091] This optional implementation reduces the compressor speed of the vehicle's air conditioning system, enabling it to operate in a low-power state. This reduces power consumption even when the desired cooling temperature cannot be determined. In one example, reducing the compressor speed directly decreases air conditioning energy consumption when the appropriate cooling temperature cannot be precisely determined, without causing a rapid rise in the vehicle's interior temperature. In another example, adjusting the compressor speed has minimal impact on user experience, satisfying basic cooling needs while achieving energy-saving goals towards the end of the journey.

[0092] In this embodiment of the application, as an optional implementation, the vehicle air conditioning system is controlled to operate in a low-power state in advance based on the remaining driving time of the target vehicle, including the following steps: When the vehicle air conditioning system is in heating mode, determine the type of the vehicle air conditioning system. When the vehicle air conditioning system is a heat pump air conditioning system, reduce the heater setting to control the vehicle air conditioning system to a low power consumption state. When the vehicle air conditioning system is a single-cooling air conditioning system, the compressor speed of the vehicle air conditioning system is reduced to control the vehicle air conditioning system to a low-power operation state.

[0093] In the above embodiments, a single-cooling air conditioning system refers to an on-board air conditioning system that only has a cooling function. A heat pump air conditioning system refers to an on-board air conditioning system that achieves heating function through a heat pump cycle, and has higher energy efficiency. The heat pump air conditioning system can be an air source heat pump air conditioning system or a water source heat pump air conditioning system.

[0094] In the above embodiments, the heater setting refers to the power setting of the heater in the heat pump air conditioning system, which determines the heating intensity.

[0095] In the above implementation, one specific way to determine the type of air conditioning system is to identify the type of air conditioning system by reading the air conditioning model in the vehicle configuration parameters.

[0096] In the above implementation, one specific way to determine the type of air conditioning system is to detect the operating mode signal of the air conditioning control system and distinguish between single heating and heat pump air conditioning systems.

[0097] In the above implementation, one specific way to reduce the heater setting is to automatically lower the heater setting by one level through the air conditioning controller, thereby reducing the heating power.

[0098] In the above embodiments, one specific way to reduce the compressor speed is to reduce the compressor speed by a preset ratio and enter a low-power heating mode.

[0099] This optional implementation can determine the specific method for reducing power consumption based on the type of the vehicle's air conditioning system, thus allowing for flexible adoption of power reduction methods when the vehicle's air conditioning system is operating in heating mode. In one example, differentiated control methods are used for different types of heating air conditioning systems, avoiding poor energy-saving effects or a decline in user experience caused by a single control strategy.

[0100] Please see Figure 2 , Figure 2 This is a schematic diagram of the structure of a vehicle air conditioning system control device provided in an embodiment of this application. Figure 2 As shown, the device includes the following functional modules: The acquisition module 201 is used to acquire the travel time of the target vehicle and the operating status of the vehicle's air conditioning system, and to determine the remaining travel time of the target vehicle. The judgment module 202 is used to determine whether the driving time of the target vehicle is greater than or equal to a first time threshold when the vehicle air conditioning system is in the on state. The control module 203 is used to control the vehicle air conditioning system to a low-power state in advance, or to control the cooling and heating functions of the vehicle air conditioning system to be turned off in advance, based on the remaining driving time of the target vehicle when the driving time of the target vehicle is greater than or equal to a first time threshold.

[0101] The device in this application embodiment can determine whether the driving time of the target vehicle is greater than or equal to a first time threshold when the vehicle's air conditioning system is in an on state. If the driving time is greater than or equal to the first time threshold, it can preemptively control the vehicle's air conditioning system to operate in a low-power state based on the remaining driving time, or preemptively shut down the cooling and heating functions of the vehicle's air conditioning system. This prevents the vehicle's air conditioning system from generating excess energy that cannot be used after the journey ends, thus avoiding energy waste caused by the system stopping abruptly at the end of the journey. Furthermore, it also avoids the need to manually turn off the air conditioning.

[0102] Please see Figure 3 , Figure 3 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application. For example... Figure 3 As shown, the electronic device includes: Processor 301; and The memory 302 is configured to store machine-readable instructions that, when executed by the processor 301, perform the method as described in any of the foregoing embodiments.

[0103] The electronic device in this embodiment of the application, by executing the vehicle air conditioning system control method, can determine whether the driving time of the target vehicle is greater than or equal to a first time threshold when the vehicle air conditioning system is in the on state. If the driving time of the target vehicle is greater than or equal to the first time threshold, it can control the vehicle air conditioning system to operate in a low-power state in advance based on the remaining driving time of the target vehicle, or control the cooling and heating functions of the vehicle air conditioning system to be turned off in advance. This avoids the vehicle air conditioning system generating excess energy that cannot be used after the trip ends, thus preventing the vehicle air conditioning system from stopping directly when the trip ends and causing energy waste. Furthermore, it also avoids the need to manually turn off the air conditioning.

[0104] This application also provides a storage medium storing a computer program, which is executed by a processor using the method described in any of the foregoing embodiments.

[0105] The storage medium in this embodiment executes a vehicle air conditioning system control method. When the vehicle air conditioning system is in an on-state characterization, it determines whether the vehicle's travel time is greater than or equal to a first time threshold. If the travel time is greater than or equal to the first time threshold, it controls the vehicle air conditioning system to operate in a low-power state based on the remaining travel time, or controls the cooling and heating functions of the vehicle air conditioning system to shut down in advance. This prevents the vehicle air conditioning system from generating excess energy that cannot be used after the trip ends, thus avoiding energy waste caused by the system stopping abruptly at the end of the trip. Furthermore, it avoids the need to manually turn off the air conditioning.
