[0002] Energy management, a hot topic and a challenge in the field of new energy vehicles, is a core technology that directly determines a vehicle's economy, power, and drivability. Passenger compartment thermal management is a crucial part of energy management in new energy vehicles; the quality and reliability of passenger compartment thermal control strategies directly determine vehicle comfort and energy consumption.

[0003] Currently, traditional passenger compartment thermal control strategies typically involve adjusting the passenger compartment temperature by turning on the vehicle's air conditioning system based on the user's set temperature, or automatically monitoring the deviation between the actual passenger compartment temperature and the preset temperature. If the deviation exceeds a certain threshold, the vehicle's air conditioning system will automatically turn on to heat or cool the passenger compartment, and then stop heating or cooling once the passenger compartment reaches the target temperature.

[0004] Existing passenger cabin thermal control strategies cannot achieve intelligent optimization when faced with various complex travel scenarios. For example, in scenarios such as short-distance travel or when the vehicle is about to reach its destination, there are unnecessary issues with heating or cooling of the passenger cabin.

It is obvious that the drawings described below are merely some embodiments of this application, and those skilled in the art can obtain other drawings based on these drawings without inventive effort.

[0064] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0065] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0066] In current new energy vehicles, the traditional passenger compartment thermal control strategy is usually based on the user's set temperature. The vehicle's air conditioning is turned on to adjust the temperature of the passenger compartment, and then stops heating or cooling once the set temperature is reached. Alternatively, it can automatically monitor the deviation between the actual temperature of the passenger compartment and the preset temperature. If the deviation exceeds a certain threshold, the vehicle's air conditioning is automatically turned on to heat or cool, and then stops heating or cooling once the target temperature is reached.

[0067] However, in certain scenarios, such as short-distance travel or when the vehicle is about to reach its destination, it is not necessary to continue heating or cooling the passenger compartment at the set temperature during the remaining travel distance and time, since the vehicle will soon stop. Continuing to heat or cool the passenger compartment at the set temperature until the end of the trip may increase unnecessary energy consumption.

[0068] Therefore, for existing new energy vehicles, the existing passenger compartment thermal control methods have the problem of unnecessary heating or cooling of the passenger compartment in short-distance travel or when the vehicle is about to reach its destination, which increases the vehicle's energy consumption.

[0069] To address the aforementioned issues, this application proposes a thermal control method for the passenger compartment of a new energy vehicle. By predicting the remaining driving distance and duration of the target vehicle using navigation information, and combining the prediction results with the operating mode of the vehicle's air conditioning, predictive thermal control of the passenger compartment is performed. This method avoids unnecessary heating or cooling of the passenger compartment while ensuring user comfort, thereby reducing vehicle energy consumption.

[0070] The technical solution of the passenger compartment thermal control method for new energy vehicles provided in this application will be described in detail below through specific embodiments. It should be noted that the following embodiments may exist alone or in combination with each other, and the same or similar content may not be described again in different embodiments.

[0071] It should be noted that the execution subject of the new energy vehicle passenger compartment thermal control method provided in this application embodiment can be the vehicle system or the cloud server. When the execution subject is the cloud server, the cloud server and the target vehicle communicate and connect through vehicle networking or other means.

[0072] Compared to in-vehicle infotainment systems, cloud servers possess superior computing and data processing capabilities. Therefore, using cloud servers as the execution source results in faster execution speeds, lower hardware requirements for the vehicle, and no additional cost to the vehicle.

[0073] The cloud server may store data related to multiple vehicles, and the VIN (Vehicle Identification Number) can be used as an identification index to store the data of the corresponding vehicle.

[0074] Figure 1 A flowchart illustrating a thermal control method for the passenger compartment of a new energy vehicle, as provided in this application embodiment, is shown below. Figure 1 In some embodiments, the process of the thermal control method for the passenger compartment of the new energy vehicle includes the following steps:

[0075] S101, obtain navigation information of the target vehicle, and obtain the driving distance and driving time of the target vehicle from the destination based on the navigation information; wherein, the navigation information includes distance information and vehicle speed information.

[0076] Among these, the remaining distance and travel time of the target vehicle from its destination can be obtained through navigation information. Most existing navigation applications have the function of predicting travel distance and travel time, which is generally done by using distance and speed information from the navigation data.

[0077] Specifically, the route information includes data such as departure point, destination, driving route, navigation location, and road conditions. The remaining driving distance of the target vehicle can be obtained by using the target vehicle's navigation location and driving route.

[0078] Specifically, the vehicle speed information includes the estimated speed predicted based on road conditions in the navigation information. Based on the remaining driving distance and the estimated speed, the remaining driving time can be obtained.

[0079] S102, if the driving distance is less than the preset distance and the driving time is less than the first preset time, then control the target vehicle to execute the passenger compartment predictive heat control mode according to the working mode of the vehicle air conditioner in the target vehicle.

[0080] The passenger compartment predictive thermal control mode includes: if the operating mode is cooling mode, the cooling temperature of the vehicle air conditioner will be increased; if the operating mode is heating mode, the heating temperature of the vehicle air conditioner will be decreased.

[0081] Specifically, if the remaining driving distance is less than a preset distance and the remaining driving time is less than a first preset time, it indicates that the target vehicle is about to reach its destination. Under these conditions, the system can determine whether the passenger compartment is heating or cooling based on the vehicle's air conditioning operating mode, and then adjust the heating or cooling temperature of the air conditioning system to reduce its energy consumption.

[0082] Specifically, when the vehicle's air conditioning is in cooling mode, appropriately increase the cooling temperature. For example, if the current cooling temperature is 25 degrees Celsius, increase it to 27 degrees Celsius. In cooling mode, increasing the cooling temperature will reduce energy consumption, thus lowering the vehicle's overall energy consumption.

[0083] Specifically, when the vehicle's air conditioning is in heating mode, appropriately lower the heating temperature. For example, if the current heating temperature is 25 degrees Celsius, lower it to 23 degrees Celsius. In heating mode, lowering the heating temperature reduces energy consumption, thus lowering the vehicle's energy consumption.

[0084] Moreover, since the target vehicle is about to reach its destination, the heating or cooling temperature of the vehicle's air conditioning can be adjusted appropriately according to the heating or cooling status of the passenger compartment. When the target vehicle finishes its journey, the temperature change in the passenger compartment will not be significant and will not affect the comfort of the passenger compartment.

[0085] In this embodiment, the remaining travel distance and travel time of the target vehicle are obtained through navigation information. Based on the obtained travel distance and travel time, it is determined whether the target vehicle is on a short trip or about to reach its destination. If the target vehicle is on a short trip or about to reach its destination, it is further determined whether the target vehicle can execute the passenger compartment predictive thermal control mode based on the judgment conditions. In this mode, the target vehicle adjusts the heating or cooling temperature of the vehicle air conditioner according to the operating mode of the vehicle air conditioner to reduce the energy consumption of the vehicle air conditioner, thereby achieving the effect of reducing the energy consumption of the target vehicle.

[0086] In some embodiments, the method further includes: if the target vehicle meets one or more of the following abnormal conditions, controlling the target vehicle to stop executing the passenger compartment predictive thermal control mode, the abnormal conditions including:

[0087] The following are possible causes: a battery management system malfunction in the target vehicle; a vehicle thermal management system malfunction in the target vehicle; an abnormal ambient temperature in the target vehicle; the blower airflow of the vehicle's air conditioning system exceeding the preset airflow; or the duration during which the target vehicle stops executing the passenger compartment predictive thermal control mode being less than the second preset duration.

[0088] In this embodiment, the role of the abnormal conditions is that if the target vehicle meets any one of the abnormal conditions, it indicates that the target vehicle is in an abnormal state, and it is not suitable to execute the passenger compartment predictive thermal control mode at this time. If the target vehicle is currently executing the passenger compartment predictive thermal control mode, the execution of the passenger compartment predictive thermal control mode is stopped; if the target vehicle is not currently executing the passenger compartment predictive thermal control mode, the execution of the passenger compartment predictive thermal control mode is prohibited.

[0089] Specifically, a malfunction in the target vehicle's battery management system or vehicle thermal management system indicates that the vehicle is in a faulty state. In this state, normal thermal control of the passenger compartment cannot be guaranteed. If the passenger compartment predictive thermal control mode is executed at this time, it may fail to properly adjust the heating or cooling temperature of the vehicle's air conditioning, potentially affecting the comfort of passengers. Therefore, if the target vehicle meets this condition, it needs to stop executing the passenger compartment predictive thermal control mode.

[0090] Specifically, if the ambient temperature around the target vehicle is abnormal, it generally indicates that the ambient temperature is too high or too low, exceeding the preset temperature range. If the passenger compartment predictive thermal control mode is activated at this time to adjust the heating or cooling temperature of the vehicle's air conditioning, the excessively high or low ambient temperature may reduce passenger comfort and negatively impact the user experience. Therefore, to ensure passenger comfort, the passenger compartment predictive thermal control mode should be discontinued in this situation.

[0091] Specifically, if the blower airflow of the vehicle's air conditioning system exceeds the preset airflow, it generally indicates that the blower airflow is too high, suggesting a strong demand for heating or cooling. If the passenger compartment predictive thermal control mode is activated at this time, adjusting the heating or cooling temperature of the vehicle's air conditioning system and reducing its heating or cooling efficiency may decrease passenger comfort and negatively impact the user experience. Therefore, to ensure passenger comfort, the passenger compartment predictive thermal control mode should be discontinued at this point.

[0092] Specifically, if the duration for which the target vehicle stops executing the passenger compartment predictive thermal control mode is less than the second preset duration, it indicates that the interval since the last execution of the passenger compartment predictive thermal control mode is too short. Continuously entering the passenger compartment predictive thermal control mode may cause the passenger compartment temperature to remain outside the user-set temperature for an extended period, affecting the user experience. Therefore, to ensure passenger compartment comfort, the passenger compartment predictive thermal control mode is stopped at this point.

[0093] In one feasible implementation, the method further includes: if the target vehicle does not meet one or more of the following reliable conditions, then controlling the target vehicle to stop executing the passenger compartment predictive thermal control mode, the reliable conditions include: reliable route information, reliable vehicle speed information, reliable navigation information, and the target vehicle being ready to start.

[0094] In this embodiment, the role of the confidence condition is to indicate that the target vehicle is suitable for executing the passenger compartment predictive thermal control mode only if all the conditions in the abnormal conditions are met. If any condition in the confidence condition is not met, and the target vehicle is currently executing the passenger compartment predictive thermal control mode, then the execution of the passenger compartment predictive thermal control mode is stopped; if the target vehicle is not currently executing the passenger compartment predictive thermal control mode, then the execution of the passenger compartment predictive thermal control mode is prohibited.

[0095] Specifically, reliable route information is crucial because the remaining driving distance and duration of the target vehicle are obtained from the route information in the navigation system. Therefore, route information can indirectly reflect the accuracy of driving distance and duration. Only when the route information is reliable can the accuracy of the obtained driving distance and duration be guaranteed, ensuring that the target vehicle can correctly determine whether to execute the passenger compartment predictive thermal control mode.

[0096] Specifically, vehicle speed information is reliable because the remaining driving time of the target vehicle is obtained based on the remaining driving distance and the estimated speed. Therefore, vehicle speed information can indirectly reflect the accuracy of the driving time. Thus, only when the vehicle speed information is reliable can the accuracy of the obtained driving time be guaranteed, ensuring that the target vehicle can correctly determine whether to execute the occupant compartment predictive thermal control mode.

[0097] Specifically, navigation information is crucial because the target vehicle relies on it to determine the remaining distance and travel time to its destination, thus determining when to execute the passenger compartment predictive thermal control mode. Therefore, only when the navigation information is reliable can the accuracy of the remaining distance and travel time be guaranteed, ensuring the target vehicle can correctly determine whether to execute the passenger compartment predictive thermal control mode. The reliability of the navigation information is determined by whether it is updated correctly.

[0098] Specifically, regarding the vehicle's readiness for startup, in hybrid and pure electric vehicles, the engine may not necessarily start after the vehicle is started. Without engine noise, it's difficult for the user to determine if the vehicle has started successfully. Therefore, a "READY" indicator light is placed on the vehicle's dashboard to indicate that the vehicle is ready to start. Thus, by collecting the target vehicle's start-ready signal, it can be determined whether the vehicle is in a start-ready state. If the target vehicle is start-ready, it indicates that the vehicle's self-check is normal and its operating condition is normal. Meeting this condition ensures that the target vehicle can correctly execute the passenger compartment predictive thermal control mode.

[0099] Preferably, the method further includes: obtaining the distance of the navigation route based on the route information; obtaining an estimated distance based on the difference between the distance and the driving distance; obtaining the actual vehicle speed based on the historical driving data of the target vehicle, and integrating the actual vehicle speed over time to obtain the actual distance; obtaining a first deviation value based on the difference between the actual distance and the estimated distance; and determining that the route information is reliable if the first deviation value does not exceed a first preset deviation range.

[0100] In this embodiment, since the timing of executing the passenger compartment predictive thermal control mode is determined by the driving distance and driving time obtained from the navigation information, accurate and reliable driving distance and driving time are necessary to ensure that the target vehicle can correctly determine whether the passenger compartment predictive thermal control mode can be executed.

[0101] The route information in the navigation information can reflect the accuracy of the driving distance and driving time. If the first deviation value between the estimated distance and the actual distance does not exceed the first preset deviation range, it indicates that the predicted distance is reliable. Correspondingly, the driving distance and driving time obtained from the navigation information are also reliable. At this time, the driving distance and driving time can also correctly determine whether the target vehicle can execute the passenger compartment predictive thermal control mode.

[0102] Preferably, the method further includes: obtaining the estimated speed of the target vehicle based on the vehicle speed information; obtaining a second deviation value based on the difference between the estimated speed and the actual speed of the target vehicle; and determining that the vehicle speed information is reliable if the second deviation value does not exceed a second preset deviation range.

[0103] In this embodiment, since the timing of executing the passenger compartment predictive thermal control mode is determined by the driving distance and driving time obtained from the navigation information, accurate and reliable driving distance and driving time are necessary to ensure that the target vehicle can correctly determine whether the passenger compartment predictive thermal control mode can be executed.

[0104] The vehicle speed information in the navigation information can reflect the accuracy of the travel time. If the second deviation value between the estimated vehicle speed and the actual vehicle speed does not exceed the second preset deviation range, it indicates that the predicted vehicle speed is reliable. Correspondingly, the travel time obtained from the navigation information is also reliable. At this time, the travel time can also correctly determine whether the target vehicle can execute the passenger compartment predictive thermal control mode.

[0105] Preferably, the method further includes: obtaining the update time of the navigation information; obtaining the interval duration based on the difference between the update time and the current time; and determining that the navigation information is reliable if the interval duration does not exceed a third preset duration.

[0106] In this embodiment, the time interval between the navigation information update time and the current time is used to determine whether the navigation information is updated normally. If the time interval exceeds a third preset time, it indicates that the navigation information has timed out and has not been updated, and the navigation information update is determined to be abnormal. If the time interval does not exceed the third preset time, the navigation information update is determined to be normal. Under the condition that the navigation information is updated normally, the navigation information is determined to be reliable.

[0107] Accurate navigation information is only obtained when navigation information is updated normally, which in turn allows for accurate determination of driving distance and duration, and ultimately, whether the target vehicle can execute the passenger compartment predictive thermal control mode. Therefore, this embodiment determines the reliability of navigation information based on its normal updates.

[0108] In some embodiments, the method further includes: obtaining the execution duration of the passenger compartment predictive thermal control mode; if the execution duration exceeds a fourth preset duration, or the target vehicle reaches its destination, controlling the target vehicle to stop executing the passenger compartment predictive thermal control mode.

[0109] In this embodiment, after the target vehicle executes the passenger compartment predictive thermal control mode, the duration of the execution of the passenger compartment predictive thermal control mode needs to be monitored. If the execution duration exceeds a fourth preset duration, the target vehicle is controlled to stop executing the passenger compartment predictive thermal control mode. The purpose is to prevent the temperature inside the passenger compartment from remaining outside the user-set temperature for an extended period, thus affecting the user experience. Therefore, to ensure passenger compartment comfort, the execution of the passenger compartment predictive thermal control mode is stopped at this time.

[0110] In addition, once the target vehicle reaches its destination, it is also controlled to stop executing the passenger compartment predictive thermal control mode, because at this time the target vehicle has completed its journey and there is no need to perform predictive thermal control on the passenger compartment anymore.

[0111] exist Figure 1 The thermal control method for the passenger compartment of the new energy vehicle shown requires increasing the cooling temperature of the vehicle's air conditioning system. The following section will discuss this further. Figure 2This paper further introduces the content regarding improving the cooling temperature of the vehicle air conditioner in the technical solution of the above-mentioned thermal control method for the passenger compartment of new energy vehicles.

[0112] Figure 2 This is a schematic flowchart illustrating the operation of increasing the cooling temperature of the vehicle's air conditioning system in the passenger compartment thermal control method for new energy vehicles provided in this application embodiment. (See attached diagram.) Figure 2 In some embodiments, the process of increasing the cooling temperature of the vehicle air conditioner includes the following steps:

[0113] S201, Based on the mapping relationship between the ambient temperature of the target vehicle, the air volume of the blower of the vehicle air conditioner and the first correction coefficient, determine the first correction coefficient.

[0114] When using a vehicle's air conditioning system, it's crucial to balance passenger comfort with achieving the desired cooling temperature. This requires considering factors such as ambient temperature and the airflow from the air conditioner's blower. For instance, lower ambient temperatures or lower blower airflow will result in a smaller temperature increase. This is because large temperature differences can significantly impact passenger comfort and user experience, as these factors can negatively affect the passenger compartment's comfort.

[0115] Therefore, through experiments, the mapping relationship between ambient temperature, blower air volume and the first correction coefficient was pre-calibrated to obtain the first correction coefficient under different ambient temperatures and blower air volumes without affecting the comfort of the passenger compartment. The corresponding first correction coefficient was then determined based on the ambient temperature and blower air volume for subsequent adjustment of the vehicle air conditioning cooling temperature.

[0116] S202, the requested temperature of the evaporator in the vehicle air conditioner is corrected according to the first correction factor to obtain the corrected temperature.

[0117] In the cooling mode of a vehicle's air conditioning system, the evaporator is a crucial component. It absorbs heat from the vehicle's interior and brings it into contact with the refrigerant, thereby lowering the interior temperature. A lower evaporator temperature means a lower refrigerant temperature within the evaporator, allowing for more efficient heat absorption and thus better cooling. Therefore, the requested evaporator temperature reflects the target cooling temperature of the air conditioning system. Adjusting the requested evaporator temperature using a first correction factor is equivalent to adjusting the target cooling temperature. Specifically, the corrected temperature is higher than the requested temperature.

[0118] S203, based on the corrected mapping relationship between temperature and compressor speed in the vehicle air conditioner, determine the target compressor speed.

[0119] The compressor is a crucial component of a vehicle's air conditioning system. Its function is to pump low-pressure refrigerant into a high-pressure state, thereby improving cooling capacity and efficiency. When the compressor speed increases, the compressor power increases, the refrigerant pressure within the compressor also increases, the refrigerant's transmission speed within the system increases accordingly, and more refrigerant is discharged, improving the cooling effect. Conversely, when the compressor speed decreases or stops, the refrigerant's transmission speed within the vehicle's air conditioning system decreases, and the cooling capacity decreases. Therefore, the cooling temperature of the vehicle's air conditioning system can be adjusted by regulating the compressor speed.

[0120] Through experiments, the compressor speed corresponding to different correction temperatures was pre-calibrated, and the target compressor speed was determined by the correction temperature for subsequent adjustment of the vehicle air conditioning cooling temperature.

[0121] S204, adjust the current compressor speed of the vehicle air conditioner to the target compressor speed according to the target compressor speed; wherein the target compressor speed is less than the current compressor speed.

[0122] The process involves adjusting the current compressor speed of the vehicle's air conditioning system to the target compressor speed. Since the target compressor speed is lower than the current compressor speed, the refrigerant transmission speed is reduced accordingly, and the cooling capacity is also reduced accordingly, thereby achieving the goal of increasing the cooling temperature of the vehicle's air conditioning system.

[0123] In this embodiment, ambient temperature and blower air volume are used as conditional parameters for the adjustable range of vehicle air conditioning cooling temperature. Without affecting the comfort of the passenger compartment, the improved cooling temperature of the vehicle air conditioning is determined, and the improved cooling temperature is adjusted by adjusting the compressor speed.

[0124] exist Figure 1 The passenger compartment thermal control method for new energy vehicles, as shown, requires lowering the heating temperature of the vehicle's air conditioning system. The following section will discuss this in conjunction with... Figure 3 This paper further introduces the content regarding reducing the heating temperature of the vehicle air conditioner in the technical solution of the above-mentioned thermal control method for the passenger compartment of new energy vehicles.

(See attached diagram.) Figure 3 In some embodiments, the process of reducing the heating temperature of the vehicle air conditioner includes the following steps:

[0126] S301, Based on the mapping relationship between the ambient temperature of the target vehicle, the air temperature of the heat exchanger in the vehicle air conditioner, and the second correction coefficient, determine the second correction coefficient.

[0127] When using a vehicle's air conditioning system for heating, it's crucial to balance passenger comfort with lowering the heating temperature. This requires considering both the ambient temperature and the air temperature of the air conditioner's heat exchanger. For example, the higher the ambient temperature or the higher the heat exchanger's air temperature, the smaller the temperature reduction the air conditioner can achieve. This is because a large temperature difference in the heating setting can easily affect the passenger compartment's comfort, negatively impacting the user experience.

[0128] Therefore, through experiments, the mapping relationship between ambient temperature, heat exchanger air temperature and the second correction coefficient was pre-calibrated to obtain the second correction coefficient under different ambient temperature and heat exchanger air temperature conditions without affecting the comfort of the passenger compartment. The corresponding second correction coefficient was then determined based on the ambient temperature and heat exchanger air temperature for subsequent adjustment of the vehicle air conditioning heating temperature.

[0129] S302, the target water temperature of the refrigerant in the vehicle air conditioner is corrected according to the second correction coefficient to obtain the corrected water temperature.

[0130] In the vehicle's air conditioning heating mode, the target refrigerant temperature reflects the target heating temperature. Therefore, correcting the target refrigerant temperature using a second correction coefficient is equivalent to adjusting the target heating temperature of the vehicle's air conditioning system. Specifically, the corrected temperature is lower than the target temperature.

[0131] S303, based on the mapping relationship between corrected water temperature and water pump flow rate in vehicle air conditioning, determines the target water pump flow rate.

[0132] The water pump in a vehicle's air conditioning system is a crucial component. It circulates refrigerant and other substances to the evaporator and compressor, enabling the air conditioning to cool or heat. The water pump flow rate affects the cooling or heating performance of the vehicle's air conditioning system. Therefore, the heating temperature of the vehicle's air conditioning system can be adjusted by regulating the water pump flow rate.

[0133] Through experiments, the corresponding water pump flow rate at different corrected water temperatures was pre-calibrated, and the target water pump flow rate was determined by the corrected water temperature for subsequent adjustment of the vehicle air conditioning heating temperature.

[0134] S304, adjust the current water pump flow rate of the vehicle air conditioner to the target water pump flow rate according to the target water pump flow rate; wherein the target water pump flow rate is less than the current water pump flow rate.

[0135] The process involves adjusting the current water pump flow rate of the vehicle's air conditioning system to the target water pump flow rate. Since the target water pump flow rate is lower than the current water pump flow rate, the refrigerant transmission speed and flow rate are reduced accordingly, and the heating capacity is also reduced accordingly, thereby achieving the goal of lowering the heating temperature of the vehicle's air conditioning system.

[0136] In this embodiment, ambient temperature and evaporator air temperature are used as conditional parameters for the adjustable range of the vehicle air conditioning heating temperature. Without affecting the comfort of the passenger compartment, the increased heating temperature of the vehicle air conditioning is determined, and the heating temperature is reduced by adjusting the water pump flow rate.
