[0002] With the in-depth involvement of high-tech enterprises in the electric vehicle industry, electric vehicles are no longer just a means of transportation, but are showing a development trend of intelligence, integration, and service. Among them, user cabin thermal comfort has become an important consideration in the design of modern electric vehicles. Through the joint action of multiple systems and technologies, users can be provided with the best comfort experience.

[0003] In the related technology, the in-car comfort temperature target and the in-car contact temperature target can be determined based on the user's heating request, and then the user cabin air conditioner can be controlled to use the in-car air temperature target as the target temperature for heating, and the user seat can be controlled to use the in-car contact temperature target as the target temperature for heating; it can also be determined whether to heat the in-car seats and whether to ventilate the in-car seats based on the parameters monitored by the in-car air conditioner; and when heating or ventilating the in-car seats, the air volume of the in-car air conditioner blower can be reduced.

[0004] However, the related technology only simply superimposes the two functions of passenger compartment air conditioning and seat heating / ventilation adjustment, which makes the response speed of electric vehicles slow, the temperature control of the user cabin is not precise enough, which reduces the user's car experience and cannot meet the user's refined comfort needs, and is in urgent need of improvement. Summary of the invention

[0006] The first aspect of the present application provides a method for controlling the thermal comfort of an electric vehicle, comprising the following steps: determining an evaluation index for the thermal comfort of an electric vehicle based on a target thermal comfort evaluation model; obtaining a temperature control strategy for a seat and / or air conditioner of the electric vehicle according to the evaluation index; adjusting the temperature of the seat and / or air conditioner using the temperature control strategy to obtain an adjusted temperature of the seat and / or air conditioner, and obtaining a thermal comfort control result that meets preset evaluation conditions based on the adjusted temperature and the evaluation index.

[0007] Through the above technical scheme, the evaluation index of thermal comfort of electric vehicles can be determined based on the target thermal comfort evaluation model, and then the temperature control strategy of the electric vehicle seat and / or air conditioner can be determined, and the temperature can be adjusted using the temperature control strategy to generate a thermal comfort control result that meets certain evaluation conditions. Through the target thermal comfort evaluation model, the thermal comfort condition in the electric vehicle can be accurately evaluated, and a targeted temperature control strategy can be formulated based on the evaluation index, so that the temperature adjustment of the seat and air conditioner is more precise, which can meet the personalized needs of different users for thermal comfort, enhance user experience, improve user satisfaction with electric vehicles, and enhance user loyalty to electric vehicle brands.

[0008] Optionally, in one embodiment of the present application, the evaluation index of thermal comfort of an electric vehicle is determined based on a target thermal comfort evaluation model, including: determining a first evaluation index among the evaluation indexes based on a local thermal sensation index of the target thermal comfort evaluation model; determining a second evaluation index among the evaluation indexes based on a local thermal comfort index of the target thermal comfort evaluation model; determining a third evaluation index among the evaluation indexes based on an overall thermal sensation index of the target thermal comfort evaluation model; determining a fourth evaluation index among the evaluation indexes according to an overall thermal comfort index of the target thermal comfort evaluation model; and determining the evaluation index based on at least one of the first evaluation index, the second evaluation index, the third evaluation index and the fourth evaluation index.

[0009] Through the above technical scheme, the evaluation index of thermal comfort of electric vehicles can be determined by the local thermal sensation index, local thermal comfort index, overall thermal sensation index and overall thermal comfort index of the target thermal comfort evaluation model. By comprehensively considering multiple evaluation indicators such as the local thermal sensation index, the local thermal comfort index, the overall thermal sensation index and the overall thermal comfort index, the thermal comfort conditions in electric vehicles can be more comprehensively and accurately reflected, avoiding only focusing on the overall thermal sensation or the overall thermal comfort while ignoring the importance of local thermal sensation and local thermal comfort, making the evaluation results more accurate and reliable, further improving the accuracy of the evaluation, and making the adjusted temperature more in line with the thermal comfort needs of users.

[0010] Optionally, in one embodiment of the present application, the temperature control strategy of the electric vehicle seat and / or air conditioner is obtained according to the evaluation index, including: obtaining the temperature of the electric vehicle; when the temperature meets a first preset temperature, determining that the temperature control strategy of the seat and / or air conditioner is a one-button heating control strategy based on the evaluation index and the temperature; when the temperature meets a second preset temperature, determining that the temperature control strategy of the seat and / or air conditioner is a one-button cooling control strategy based on the evaluation index and the temperature.

[0011] Through the above technical scheme, when the temperature of the electric vehicle meets the first certain temperature, the temperature control strategy can be determined as a one-button heating control strategy; when the second certain temperature is met, the temperature control strategy can be determined as a one-button cooling control strategy.

When the linkage function is not turned on, the temperature control strategy is determined based on the evaluation index and the temperature. When the linkage function is turned on, it can ensure that the temperature adjustment of the seat and the air conditioner is more coordinated and consistent, thereby improving the overall thermal comfort. When the linkage function is not turned on, the temperature control strategy of the seat and the air conditioner can be determined independently based on the evaluation index and the temperature, providing users with more choices and making temperature control more convenient and flexible.

By continuously monitoring and adjusting the temperature until it reaches a certain temperature, it can ensure that the temperature control is more precise, which helps to improve the overall riding experience, and can also avoid large temperature fluctuations, improve the thermal comfort control effect, and thus ensure that the in-vehicle environment always remains within the thermal comfort level expected by the user, thereby improving the user's comfort.

[0019] Through the above technical scheme, the evaluation index of thermal comfort of electric vehicles can be determined by the local thermal sensation index, local thermal comfort index, overall thermal sensation index and overall thermal comfort index of the target thermal comfort evaluation model. By comprehensively considering multiple evaluation indicators such as the local thermal sensation index, the local thermal comfort index, the overall thermal sensation index and the overall thermal comfort index, the thermal comfort conditions in electric vehicles can be more comprehensively and accurately reflected, avoiding only focusing on the overall thermal sensation or the overall thermal comfort while ignoring the importance of local thermal sensation and local thermal comfort, making the evaluation results more accurate and reliable, further improving the accuracy of the evaluation, and making the adjusted temperature more in line with the thermal comfort needs of users.

[0041] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0042] The following describes the thermal comfort control method, device, electric vehicle, medium and program product of the embodiment of the present application with reference to the accompanying drawings. In view of the problem mentioned in the above background technology that the two functions of passenger compartment air conditioning and seat heating / ventilation adjustment are simply superimposed, which makes the response speed of the electric vehicle slow, the temperature control of the user cabin is not accurate enough, reduces the user's car experience, and cannot meet the user's refined comfort needs, the present application provides a control method for thermal comfort of an electric vehicle, in which an evaluation index of thermal comfort of the electric vehicle can be determined based on a target thermal comfort evaluation model, and then a temperature control strategy of the electric vehicle seat and / or air conditioner is determined, and the temperature is adjusted using the temperature control strategy, so as to generate a thermal comfort control result that meets certain evaluation conditions, and through the target thermal comfort evaluation model, the thermal comfort condition in the electric vehicle can be accurately evaluated, and a targeted temperature control strategy can be formulated according to the evaluation index, so that the temperature adjustment of the seat and air conditioner is more accurate, which can meet the personalized needs of different users for thermal comfort, enhance user experience, improve user satisfaction with the electric vehicle, and enhance user loyalty to the electric vehicle brand. This solves the problem that in the related technology, the two functions of passenger compartment air conditioning and seat heating / ventilation adjustment are simply superimposed, resulting in a slow response speed of electric vehicles, inaccurate temperature control in the user cabin, reduced user experience, and inability to meet users' refined comfort needs.

[0043] Specifically, Figure 1 The present invention is a flowchart of a method for controlling thermal comfort of an electric vehicle provided according to an embodiment of the present application.

[0044] like Figure 1 As shown, the electric vehicle thermal comfort control method includes the following steps:

[0045] In step S101 , an evaluation index of thermal comfort of an electric vehicle is determined based on a target thermal comfort evaluation model.

[0046] It is understandable that in the current relevant scenario modes, the electric vehicle air conditioning and seat heating / ventilation adjustment functions are generally combined to perform maximum mode heating or cooling, and link seat heating or seat ventilation. However, this kind of simple function superposition cannot respond to the user's refined comfort needs.

[0047] Therefore, on this basis, the embodiment of the present application uses the Berkely thermal comfort evaluation model as the target thermal comfort evaluation model for thermal comfort of electric vehicles, and uses this as the evaluation standard to obtain the evaluation index.

[0048] In addition, it should be noted that the target thermal comfort evaluation model of the embodiment of the present application can also be other evaluation models, which can be specifically set by technicians in this field according to actual conditions, and this application does not make any specific restrictions.

[0049] As a possible implementation method, the embodiment of the present application can obtain the evaluation index of thermal comfort of electric vehicles according to the Berkely thermal comfort evaluation model.

[0050] Optionally, in one embodiment of the present application, an evaluation index of thermal comfort of an electric vehicle is determined based on a target thermal comfort evaluation model, including: determining a first evaluation index among the evaluation indexes based on a local thermal sensation index of the target thermal comfort evaluation model; determining a second evaluation index among the evaluation indexes based on a local thermal comfort index of the target thermal comfort evaluation model; determining a third evaluation index among the evaluation indexes based on an overall thermal sensation index of the target thermal comfort evaluation model; determining a fourth evaluation index among the evaluation indexes based on an overall thermal comfort index of the target thermal comfort evaluation model; and determining the evaluation index based on at least one of the first evaluation index, the second evaluation index, the third evaluation index and the fourth evaluation index.

[0051] It can be understood that in the embodiment of the present application, the evaluation index of thermal comfort of electric vehicles may include but is not limited to four evaluation indexes, namely, local thermal sensation index, local thermal comfort index, overall thermal sensation index, and overall thermal comfort index. Figure 2 As shown, it can be specifically configured by technicians in this field according to actual conditions, and this application does not make any specific limitations.

[0052] Among them, the local thermal sensation index can be understood as the main related quantities are local temperature and local average temperature. For example, the target of seat heating / ventilation is local thermal sensation, etc. This application does not make specific restrictions.

[0053] The local thermal comfort index can be understood as the main related quantities are the local thermal sensation and the external environment temperature. For example, when the external environment is hot, if there is a local cold sensation, the comfort is high; when the external environment is cold, if there is a local heat sensation, the comfort is high, etc. This application does not make specific restrictions.

[0054] The overall thermal sensation index can be understood as the temperature sensation of the core parts, such as the back, chest and pelvis, which are mainly related to the quantity. Parts that can be physiologically isolated and parts that are exposed to clothing for a long time have little impact on the user's overall thermal sensation. In addition, the consistency of local thermal sensation, that is, whether different parts of the human body have opposite thermal sensations, will also have an effect on the overall thermal sensation. When the thermal sensations of different parts of the body are inconsistent, the user may feel uncomfortable or confused, which will affect the judgment of the overall thermal sensation.

[0055] The overall thermal comfort index can be understood as the main related quantities are the overall thermal sensation and local thermal comfort, but in a steady-state environment, the two most uncomfortable local areas play a decisive role or the third most uncomfortable local area outside the hands and feet determines the overall thermal comfort.

[0056] In addition, it should be noted that in the air conditioning strategy calibration process of the embodiment of the present application, the relevant parameters can be calibrated by means of energy dummies according to relevant algorithms to meet the comfort needs of electric vehicle users. Among them, the seat heating / ventilation is close to the user's pelvis and back, and the seat temperature control is introduced when the user has a heating or cooling request, which can achieve passenger comfort faster and more effectively, but at the same time, the temperature coordination is taken into account to avoid temperature deviation and induce temperature discomfort to the user.

[0057] Furthermore, in the embodiment of the present application, the first evaluation index can be understood as a local thermal sensation index, the second evaluation index can be understood as a local thermal comfort index, the third evaluation index can be understood as an overall thermal sensation index, and the fourth evaluation index can be understood as an overall thermal comfort index.

[0058] As a possible implementation method, the embodiment of the present application can determine the evaluation index based on at least one of the local thermal sensation index, the local thermal comfort index, the overall thermal sensation index and the overall thermal comfort index of the target thermal comfort evaluation model.

[0059] In step S102, a temperature control strategy for the electric vehicle seat and / or air conditioner is obtained according to the evaluation index.

[0060] In the actual implementation process, the embodiment of the present application can obtain the temperature control strategy of the electric vehicle seat and / or air conditioner based on the evaluation index.

[0061] Optionally, in one embodiment of the present application, a temperature control strategy for an electric vehicle seat and / or air conditioner is obtained based on an evaluation index, including: obtaining the temperature of the electric vehicle; when the temperature meets a first preset temperature, determining that the temperature control strategy for the seat and / or air conditioner is a one-button heating control strategy based on the evaluation index and the temperature; when the temperature meets a second preset temperature, determining that the temperature control strategy for the seat and / or air conditioner is a one-button cooling control strategy based on the evaluation index and the temperature.

[0062] In some embodiments, when the temperature of the electric vehicle in the embodiment of the present application meets the first certain temperature, for example, the temperature is lower than 10 degrees Celsius, a one-button temperature increase control strategy for the seat and the air conditioner can be executed based on the evaluation index. In the embodiment of the present application, the execution flow chart of the one-button temperature increase control strategy is as follows: Figure 3 As shown, its main contents are:

[0063] In the embodiment of the present application, the seat heating is turned on to ensure that the local thermal sensation at the back and pelvis is hot; the air conditioning heating is turned on, the air volume is level 1, internal circulation, and the face and feet blowing mode is set, the air outlet temperature rises to 35 degrees Celsius, and then the air volume is gradually increased. After the temperature stabilizes at 35 degrees Celsius, the air volume is increased by one level until the highest wind speed. Ensure that at the initial stage of the function, the local thermal sensation is consistent (all are hot), and the thermal sensation of the head and feet is uniform, so as to avoid the most uncomfortable local area affecting the overall comfort; the air volume is increased to level 8, and the mode is adjusted to the foot blowing mode after X minutes to maintain seat heating. After the thermal environment in the car enters a steady state, it is adjusted to the foot blowing mode to compensate for the discomfort in the foot area caused by the floating of hot air.

[0064] In addition, it should be noted that the first certain temperature can be set by technicians in this field according to actual conditions, and this application does not impose any specific restrictions.

[0065] The embodiment of the present application can use a one-button temperature rise control strategy to combine user comfort to perform switching control of modes and air volumes, thereby achieving consistency in the user's local thermal sensation and overall comfort in a cold environment.

[0066] In some embodiments, when the temperature of the electric vehicle in the embodiment of the present application meets the second certain temperature, such as the temperature is higher than 30 degrees Celsius, a one-button cooling control strategy for seats and air conditioners can be executed based on the evaluation index. In the embodiment of the present application, the execution flow chart of the one-button cooling control strategy is as follows: Figure 4 As shown, its main contents are:

[0067] In the embodiment of the present application, seat ventilation is turned on to ensure that the local thermal sensation at the back and pelvis is cold; the air conditioning is turned on for heating, with the air volume at level 1, internal circulation, and face and foot blowing mode, and the air outlet temperature is reduced to 20 degrees Celsius, and then the air volume is gradually increased. After the temperature stabilizes at 20 degrees Celsius, the air volume is increased by one level until it reaches the highest wind speed. Ensure that at the initial stage of the function being turned on, the local thermal sensations are consistent (all cold), and the thermal sensations at the head and feet are uniform, so as to avoid the most uncomfortable local areas affecting the overall comfort; the air volume is increased to level 8, and after X minutes the mode is adjusted to the face blowing mode to maintain seat ventilation. After the thermal environment in the car enters a steady state, it is adjusted to the face blowing mode to compensate for the discomfort in the head area caused by the sinking of cold air.

[0068] In addition, it should be noted that the second certain temperature can be set by technicians in this field according to actual conditions, and this application does not impose any specific restrictions.

[0069] The embodiment of the present application can use a one-button cooling control strategy to combine user comfort to perform switching control of modes and air volumes, thereby achieving consistency in the user's local thermal sensation and overall comfort in a hot environment.

[0070] In addition, the embodiment of the present application links seat heating and seat ventilation in the two control strategies of one-button heating and one-button cooling, which can achieve the goal of user's local thermal sensation faster, more effectively and more energy-efficiently, but the air-conditioning strategy needs to be adjusted to ensure the overall thermal comfort.

[0071] Optionally, in one embodiment of the present application, the temperature control strategy of the electric vehicle seat and / or air conditioner is obtained according to the evaluation index, and also includes: judging whether the linkage function of the seat and the air conditioner is turned on; if the linkage function is turned on, determining the temperature control strategy of the seat and the air conditioner as the linkage temperature control strategy based on the linkage function; if the linkage function is not turned on, determining the temperature control strategy of the seat and the air conditioner based on the evaluation index and the temperature.

[0072] It is understandable that in the current in-car thermal environment control strategy, seat heating and air conditioning control are separate, and the two are not linked when the user adjusts the air conditioning temperature and seat heating requirements separately. If the temperature is raised during seat ventilation, causing the user to feel warm locally, the back and buttocks will be cold, and the rest of the body will be warm, which will lead to a divergence in local thermal sensations and affect the overall thermal comfort. Conversely, when the seat is heated, lowering the temperature will also cause the above problems.

[0073] Therefore, the embodiment of the present application can develop a setting item, a linkage function, that is, the default air-conditioning adjustment (frequent adjustment item) is linked to the seat temperature control, and the user adjusts the set temperature, which is linked to the gear adjustment of the seat heating / ventilation: when the linkage function is turned on, the user adjusts the set temperature up / down to link the seat heating / ventilation level to ensure the consistency of the local thermal sensation of the human body; when the linkage function is not turned on, the user's adjustment of the air-conditioning set temperature is not related to the seat heating / ventilation level adjustment, and the user needs to adjust them separately.

[0074] Further, in the embodiment of the present application, when the linkage function is turned on, the execution flow chart of the linkage temperature control strategy is as follows: Figure 5 As shown, the main contents can be:

[0075] In the embodiment of the present application, when the temperature meets the first certain temperature, the heating is mainly carried out. The user increases the set temperature and the seat is adjusted to the heating state. If the seat is originally in the heating state, the heating level is increased. When the temperature meets the second certain temperature, the cooling is mainly carried out. The user decreases the set temperature and the seat is adjusted to the ventilation state. If the seat is originally in the ventilation state, the ventilation level is increased.

[0076] The embodiment of the present application can increase the functional association settings of air conditioning adjustment and seat heating / ventilation through the linkage temperature control strategy, simplify the user operation logic, optimize the human-computer experience, and improve user comfort.

[0077] In step S103, the temperature of the seat and / or the air conditioner is adjusted using a temperature control strategy to obtain an adjusted temperature of the seat and / or the air conditioner, and a thermal comfort control result that meets a preset evaluation condition is obtained based on the adjusted temperature and the evaluation index.

[0078] As a possible implementation method, the embodiment of the present application can adjust the temperature of the seat and / or air conditioner through a one-button temperature increase control strategy, a one-button temperature decrease control strategy and / or a linkage temperature control strategy, thereby obtaining the adjusted temperature of the seat and / or air conditioner, and based on the adjusted temperature and evaluation indicators, obtain a thermal comfort control result that meets certain evaluation conditions.

[0079] Among them, certain evaluation conditions can be set by technicians in this field according to actual conditions, and this application does not impose specific restrictions.

[0080] Optionally, in one embodiment of the present application, a thermal comfort control result that meets preset evaluation conditions is obtained based on the adjusted temperature and the evaluation index, including: judging whether the adjusted temperature reaches the preset temperature; if the adjusted temperature reaches the preset temperature, obtaining the thermal comfort control result based on the adjusted temperature and the evaluation index; if the adjusted temperature does not reach the preset temperature, adjusting the adjusted temperature based on the preset temperature until the adjusted temperature reaches the preset temperature.
