Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle control, in particular to a vehicle control method, device and vehicle. BACKGROUND

[0002] In order to improve the comfort experience of the driver and passenger, some vehicles provide steering wheel heating and / or ventilation functions and seat heating and / or ventilation functions. For example, in cold winter, the user can turn on the steering wheel heating function to raise the temperature of the steering wheel, so as to avoid the low temperature discomfort when the driver holds the steering wheel to drive; and the user can also start the seat heating function to improve the temperature of the seat, so as to improve the user's riding experience.

[0003] At present, the ventilation and heating function of the steering wheel / seat is realized based on the active control of the user, and cannot be automatically started, turned off or adjusted according to the personalized needs of the user, so the intelligent degree is low. At the same time, the sun irradiates the vehicle cabin, which will affect the body feeling of the driver and passenger on different seats, for example, the temperature difference of the cabin of the vehicle under the tree shade and the vehicle exposed to the sun in summer may exceed 10℃. The air conditioning system and the steering wheel / seat ventilation and heating are not associated, and the influence of the comfort influence object in the external environment on the comfort in the vehicle is not considered, which may cause poor comfort of the driver and passenger or waste of vehicle energy consumption. SUMMARY

[0004] In view of the above problems, the present application provides a vehicle control method, device and vehicle which can overcome the above problems or at least partially solve the above problems, and the technical solutions are as follows:

[0005] A vehicle control method, the vehicle at least comprising an air conditioning system and an auxiliary comfort system, the auxiliary comfort system comprising at least one of seat ventilation, seat heating, steering wheel ventilation and steering wheel heating, the method comprising: acquiring position information and influence attribute of a comfort influence object, the comfort influence object being capable of changing an environmental parameter in the vehicle cabin, the influence attribute being used to indicate the change trend of the environmental parameter; in response to the position information and / or orientation information of the vehicle, calculating the relative position information between the vehicle and the comfort influence object; adjusting the control parameter of the air conditioning system and / or the control parameter of the auxiliary comfort system according to the relative position information and the influence attribute.

[0006] In the present application, the relative position information between the vehicle and the comfort influencing object is determined through the position information and / or orientation information of the vehicle, and then the control parameter of the air conditioning system of the vehicle is adjusted according to the relative position information and the influence attribute of the comfort influencing object. On the one hand, the automatic adjustment of the air conditioning system is realized, and the disadvantage of frequent manual adjustment of the air conditioning system by the user due to the change of temperature perception is avoided. On the other hand, when the air conditioning system is adjusted according to the relative position information between the vehicle and the comfort influencing object, the influence attribute of the comfort influencing object is also considered, so that the adjusted air conditioning system can adapt to the relative position information, thereby enabling the driver and passenger of the vehicle to obtain higher air conditioning comfort and improving the comfort experience of the user. At the same time, the auxiliary comfort system can also be adjusted according to the relative position information between the vehicle and the comfort influencing object, that is, the seat function and / or steering wheel function are adjusted, and the influence attribute of the comfort influencing object is also considered during the adjustment. Not only can the automatic adjustment of the seat function and / or steering wheel function be realized, the intelligent degree of the vehicle is improved, the user obtains higher driving comfort experience, but also the adjusted auxiliary comfort system can adapt to the current position information of the vehicle, avoiding the situation that the driving experience of the user is reduced due to the influence of the comfort influencing object. Furthermore, the adjustment of the seat function and / or steering wheel function in the present application can also be adaptively adjusted according to the control parameter of the adjusted air conditioning system, thereby realizing the linkage strategy of air conditioning and seat and / or the linkage strategy of air conditioning and steering wheel, avoiding the user manually starting or closing the seat function and / or steering wheel function, improving the driving comfort experience of the user, and the scheme of adjusting the seat function and / or steering wheel function according to the control parameter of the air conditioning system also realizes the intelligent automatic adjustment of the seat function and / or steering wheel function, and the adjusted seat function and / or steering wheel function effectively adapts to the current user demand, significantly improving the comfort experience of the user.

[0007] In a possible implementation manner of the present application, adjusting the control parameter of the air conditioning system according to the relative position information and the influence attribute comprises: determining a comfort influencing area of the vehicle cabin influenced by the comfort influencing object according to the relative position information; calculating the overlap degree between the comfort influencing area and each vehicle seat area where a driver or passenger exists, respectively; when at least one overlap degree is higher than a first threshold, adjusting the control parameter of the air conditioning system according to the influence attribute, the control parameter of the air conditioning system including at least one of the air outlet angle, the air outlet volume and the heating / cooling parameter.

[0008] In this embodiment, the control parameter of the air conditioning system is adjusted according to the overlapping degree between the comfort influencing object and the vehicle seat area where the driver or passenger is located. The air conditioning system is adjusted only when the overlapping degree between the comfort influencing object and the vehicle seat area where the driver or passenger is located is higher than a first threshold, i.e., when the comfort influencing object has a great influence on the user who is located in the vehicle seat area. Thus, the air conditioning system is effectively adjusted. For example, when the comfort influencing object is the sun, the overlapping degree between the sun and the vehicle seat area where the driver or passenger is located is high, which means that the sun has a great influence on the user who is located in the vehicle seat area. In this case, the control parameter of the air conditioning system is adjusted, which can effectively improve the comfort experience of the user. This process can also avoid the ineffective adjustment of the air conditioning system when the comfort influencing object has a low influence on the vehicle seat area, thereby improving the adjustment efficiency of the air conditioning system and ensuring that each adjustment of the air conditioning system can improve the comfort experience of the user. In addition, when the air conditioning system is adjusted, the adjustment content is at least one of the air outlet angle, the air outlet volume and the heating / cooling parameter of the air conditioning system. Through the adjustment of these parameters, the user can avoid manual adjustment, and the comfort of the air conditioning system for the corresponding user can be significantly improved.

[0009] In a possible implementation of the present application, the air conditioning system is provided with an independent air outlet, which can blow air towards the vehicle seat area where the driver or passenger is located. The method further comprises: obtaining the area environment temperature detected by the corresponding temperature sensor of the vehicle seat area where the driver or passenger is located, and / or obtaining the body temperature of the driver or passenger, when the overlapping degree is higher than the first threshold; and adjusting the air outlet angle and / or the air outlet volume of the independent air outlet of the air conditioning system according to the influence attribute, when the difference between the change rate of the area environment temperature and the change rate of the overall environment temperature of the vehicle cabin is greater than a second threshold, and / or the change rate corresponding to the body temperature is greater than a third threshold.

[0010] In this embodiment, by adjusting the air outlet angle and / or air volume of the independent air outlet of the vehicle seat area with a high overlap degree higher than the first threshold, the partition adjustment of the air conditioning system is realized, on the one hand, the comfort experience of the user corresponding to the independent air outlet is improved, on the other hand, the user in other seat areas is also avoided from being affected by the adjustment of the air conditioning system, and the needs of all users in the vehicle are met; at the same time, the partition adjustment scheme is also helpful to the energy saving of the air conditioning system, only the independent air outlet corresponding to the vehicle seat area with a high overlap degree needs to be adjusted, and the overall adjustment of the air conditioning system is not needed. And in the partition adjustment, the regional environment temperature is detected by the temperature sensor corresponding to the seat area, and the body temperature of the driver and passenger in the seat area is monitored by the infrared sensor corresponding to the seat area, when the difference between the change rate of the regional environment temperature and the change rate of the overall environment temperature in the vehicle cabin is greater than the second threshold, or the change rate of the human body temperature is greater than the third threshold, the independent air outlet is adjusted, thereby the effectiveness of the parameter adjustment of the independent air outlet can be ensured, and the partition control of the air conditioning system is realized.

[0011] In a possible implementation of the present application, for the vehicle seat area with a high overlap degree higher than the first threshold, the method further comprises: predicting, according to the current driving path of the vehicle, the duration that the overlap degree between the comfort influence area and the vehicle seat area is higher than the first threshold; and adjusting the control parameter of the air conditioning system according to the influence attribute when the duration is greater than a fourth threshold.

[0012] In this embodiment, the duration of the high overlap degree between the comfort influence area and the vehicle seat area is used as one of the factors for adjusting the air conditioning system, and the air conditioning system is adjusted only when the duration is greater than the fourth threshold, so that the effectiveness of each adjustment of the air conditioning system can be ensured, and the frequent adjustment of the air conditioning system is avoided, thereby prolonging the service life of the air conditioning system.

[0013] In an implementation of the present application, the method further comprises: obtaining the remaining time to destination in the vehicle navigation information, and adjusting the control parameter of the air conditioning system and / or the auxiliary comfort system based on the relative position information or the duration, the remaining time to destination and the influence attribute.

[0014] In the present implementation, after determining that the overlap between the comfort influence area and the vehicle seat area is higher than the first threshold for a duration, the remaining time to destination in the current driving path of the vehicle or the destination navigation information is also considered, so as to avoid unnecessary adjustment of the air conditioner when the remaining time to destination is short. Meanwhile, the remaining time to destination in the current driving path of the vehicle is used as a judgment condition for adjusting the air conditioning system and / or the auxiliary comfort system, so as to avoid invalid adjustment of the air conditioning system and / or the auxiliary comfort system when the user is about to reach the destination, ensure the effectiveness of the adjustment, and save energy.

[0015] In a possible implementation of the present application, adjusting the control parameter of the auxiliary comfort system according to the relative position information and the influence attribute comprises: adjusting the control parameter of the auxiliary comfort system according to the influence attribute when at least one overlap is higher than the first threshold, and / or when the overlap between the comfort influence area and the steering wheel area is higher than the fifth threshold.

[0016] In the present implementation, the comfort influence area determined by the relative position information between the vehicle and the comfort influence object is used as a judgment condition for adjusting the seat function and / or the steering wheel function, that is, the auxiliary comfort system is adjusted when the overlap between the comfort influence area and the auxiliary comfort system is higher than the threshold, so as to adjust the seat function and / or the steering wheel function according to the relative position information, that is, even without adjusting the air conditioning system, the seat function and / or the steering wheel function can be adjusted in the present implementation, so as to avoid manual adjustment by the user, and the adjusted seat function and / or steering wheel function can effectively improve the user comfort experience.

[0017] In a possible implementation of the present application, adjusting the control parameter of the auxiliary comfort system according to the relative position information and the influence attribute comprises: judging whether the area environment temperature or the overall environment temperature is in a preset comfort temperature interval, the preset comfort temperature interval being obtained by user setting or obtained by the data related to the environment parameter in the vehicle cabin in the historical driving record of the user; if not, adjusting the control parameter of the auxiliary comfort system according to the user comfort preference and the influence attribute, the user comfort preference being obtained based on the historical data of the user operating the auxiliary comfort system.

[0018] In this embodiment, the adjustment of the steering wheel function and / or the seat function can also be based on the ambient temperature in the vehicle cabin. After the air conditioning system is adjusted, the local ambient temperature or the overall ambient temperature in the cabin is monitored, and it is determined whether the temperature is within a preset comfortable temperature range. If not, the seat function and / or the steering wheel function are adjusted. This realizes the linkage of the air conditioner and the steering wheel and / or the linkage of the air conditioner and the seat, and the adjusted seat function and / or steering wheel function can be adapted to the influencing factors, meet the actual needs of the user at the moment, avoid the poor user experience caused by mechanical adjustment in the traditional air conditioner and seat linkage scheme, realize intelligent linkage adjustment, and significantly improve the user's comfort experience. Moreover, the comfortable temperature range in this embodiment can be obtained through user settings, or obtained from the data related to the cabin environment in the historical driving records of the vehicle. At the same time, when adjusting the control parameters of the auxiliary comfort system, the user's comfort preference is also considered by comprehensively considering the historical data of the user's operation of the auxiliary comfort system, so that the adjusted auxiliary comfort system can better meet the user's comfort needs.

[0019] In a possible implementation of the present application, after the control parameters of the air conditioning system and / or the control parameters of the auxiliary comfort system are adjusted, the method further comprises: determining that the local ambient temperature or the overall ambient temperature is within the preset comfortable temperature range; obtaining the driver's body temperature; and adjusting the control parameters of the auxiliary comfort system according to the change trend of the driver's body temperature.

[0020] In this embodiment, after the control parameters of the air conditioning system and / or the auxiliary comfort system are adjusted, if the local ambient temperature and the overall ambient temperature in the vehicle cabin are within the preset comfortable temperature range, the small changes in the driver's body temperature monitored by the infrared sensor and the like can also be monitored, and the control parameters of the air conditioning system and / or the auxiliary comfort system can be fine-tuned, so that the user can obtain higher comfort experience, or the energy consumption of the vehicle can be reduced based on energy saving purposes.

The accompanying drawings are included to provide a better understanding of the preferred embodiments, and are not to be considered as limiting of the present application. Moreover, in the drawings, like reference numerals refer to similar components throughout the several views. In the drawings:

[0027] Exemplary embodiments of the present application will be described herein below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it is understood that the present application can be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0028] The present application provides a linkage control method, device and vehicle, as shown in Figure 1 Figure 1 A flow chart of a linkage control method of a vehicle is provided for an embodiment of the present application, which is applicable to a vehicle processor or controller, and can also be applicable to a corresponding processor or corresponding controller of an air conditioning system and / or auxiliary comfort system, and specifically includes the following execution steps:

[0029] Step 101, obtaining position information and influence attribute of a comfort influencing object.

[0030] During the driving of a vehicle, the sun, buildings, etc. can affect the environmental parameters in the vehicle cabin, for example, in hot summer, the sun shining on the cabin can cause the value of the environmental temperature in the cabin to rise rapidly, directly affecting the comfort experience of the user. In this embodiment, the object that can affect the environmental parameters in the cabin is referred to as a comfort influencing object during the driving of the vehicle. In an example, the comfort influencing object preferably includes the sun, and can also include buildings, trees, etc. on both sides of the road on which the vehicle is driving, but the buildings here are preferably buildings that can produce a shadow that blocks part or all of the area of the vehicle. Assuming that the shadow area produced by the sun shining on the building at the current time cannot cover the vehicle driving on the road, it is considered that the building does not have a comfort influence on the vehicle at this time. Different comfort influencing objects can have different influences on the environmental parameters in the cabin due to seasonal factors, etc. Therefore, in this embodiment, the concept of influence attribute is used to represent the influence trend of the comfort influencing factor on the environmental parameters in the cabin.

[0031] The position information of the comfort influencing object has different acquisition methods according to different comfort influencing objects. For example, when the comfort influencing object is a building, a tree, etc., its position information can be determined by the current driving map of the vehicle, such as latitude and longitude information of the building, tree, etc. When the comfort influencing object is the sun, the subsequent relative position information calculation process can be directly performed, i.e. the relative position information between the vehicle and the sun is directly calculated. The acquisition of the influence attribute can be determined in combination with factors such as the date.

[0032] Step 102, calculating the relative position information between the vehicle and the comfort influencing object in response to the position information and / or orientation information of the vehicle. ​

[0033] During the driving process, the vehicle continuously updates the position information and / or the orientation information. The position information refers to the current latitude, longitude, height, and the like of the vehicle. The orientation information refers to the direction information of the vehicle head. In an example, the position information of the vehicle can be determined by a vehicle GPS module. The orientation information of the vehicle can be obtained by an inertial measurement unit or an electronic compass of the vehicle. Both of the two sensors can provide the angle of the vehicle relative to the magnetic north, thereby obtaining the orientation information of the vehicle.

[0034] After obtaining the position information and / or the orientation information of the vehicle, the relative position information between the vehicle and the comfort influence object can be calculated by using the obtained position information of the comfort influence object. For example, when the comfort influence object is the sun, the position information of the sun is related to the current time. Therefore, the current time and the position information and / or the orientation information of the vehicle can be used to calculate the relative position information.

[0035] Specifically, taking the sun as the comfort influence object, in the calculation of the relative position information, in addition to using the obtained position information and / or the orientation information of the vehicle, the current time also needs to be obtained. The current time can be obtained by using the UTC time provided by the vehicle GPS module or the built-in clock of the vehicle. Then, the position of the sun relative to the earth is calculated. Specifically, the position of the sun relative to the earth is calculated according to the position information of the vehicle and the obtained current time by using a preset astronomical algorithm, such as a calculation formula of the sun azimuth and the sun altitude angle, and the like. The sun altitude angle refers to the angle between the sunray and the horizontal plane. The sun azimuth refers to the projection direction of the sun on the horizontal plane, which is usually measured in the clockwise direction with the north as the 0-degree reference. It should be noted that the calculation processes of the sun altitude angle and the sun azimuth can be realized by using the existing formula or the existing algorithm, and the embodiments of the present application do not repeat the description here. Finally, the sun azimuth and the sun altitude angle are compared with the orientation information of the vehicle, so as to obtain the position of the sun relative to the vehicle, that is, the relative position information between the sun and the vehicle. For example, if the sun azimuth is 90 degrees (due east) and the orientation of the vehicle is 0 degrees (due north), the sun is on the right side of the vehicle. If the sun altitude angle is low (close to the horizon), it is considered that the sun is on the horizon in front of or behind the vehicle.

[0036] In a possible implementation of the present application, the relative position information is an important basis for subsequent adjustment of the control parameters of the air conditioning system and / or the auxiliary comfort system, and the position information of the vehicle is the basis for calculating the relative position information. Therefore, accurate or precise vehicle position information directly affects the accuracy of the relative position information between the vehicle and the comfort influencing object, and further affects the effectiveness of the subsequent adjustment of the air conditioning system and / or the auxiliary comfort system. Therefore, it is particularly important to ensure the accuracy of the vehicle position information and achieve precise positioning of the vehicle.

[0037] The position information of the vehicle is preferably obtained through a GPS module. However, when the vehicle travels through a mountainous area, a city valley, or a road condition area with electronic interference, the GPS signal may not be timely, or even lost, so that the vehicle cannot obtain accurate position information. To solve this problem, in the present application, the signal strength and / or signal stability of the GPS signal in the future area to be entered by the vehicle is predicted based on the historical GPS signals received during the driving of the vehicle. Alternatively, the future area to be entered by the vehicle can be determined based on the current driving map of the vehicle, and the signal strength and / or signal stability of the GPS signal can be predicted based on the topography and other features of the area to be entered. Then, whether the vehicle meets the precise positioning condition in the area to be entered is determined based on the predicted signal strength and / or signal stability of the GPS signal. In an example, the precise positioning condition can be set by the signal strength and / or signal stability, for example, by setting a threshold value of the signal strength and / or signal stability. When the signal strength and / or signal stability is not less than a certain value, it is considered that the precise positioning condition is met. It should be noted that the prediction process of the GPS signal can be realized by a machine learning algorithm. By analyzing and learning the reception of historical GPS signals, or by learning the change of the GPS signal in a specific area from a large amount of data, the change of the future GPS signal can be predicted. The specific machine learning process can be realized by an existing algorithm, which will not be described herein.

[0038] Further, if it is determined that the vehicle cannot achieve precise positioning in the area to be entered in the future based on the predicted signal strength and / or signal stability, positioning compensation can be performed to achieve precise positioning of the vehicle and ensure that the vehicle can obtain accurate position information.

[0039] 1) Map data preloading: Before the vehicle enters an area with poor signal or susceptible to interference, high-precision map data of the area, including road network, topographic features, and other information, is downloaded and stored in advance, so that the vehicle can still navigate based on the stored map data when the GPS signal is lost, thereby ensuring that accurate position information of the vehicle can be obtained.

[0040] 2) Multi-source positioning fusion: In addition to relying on GPS signals, the vehicle's auxiliary positioning system can be activated before entering areas with poor signal reception or susceptibility to interference, combined with other positioning technologies such as GLONASS satellite navigation system, GALILEO satellite navigation system, Beidou satellite navigation system, as well as base station positioning, WIFI positioning, inertial navigation system, etc. Through positioning data fusion, the positioning accuracy and stability can be improved.

[0041] 3) Path planning optimization: Before the vehicle enters an area with poor signal reception or susceptibility to interference, an alternative path can be planned in advance, choosing a route with good signal reception conditions as the alternative path to avoid entering the signal blind area, thereby maintaining high-precision positioning.

[0042] 4) Real-time road condition update: Through vehicle networking, mobile communication network, etc., real-time road condition information such as road construction, accident, traffic congestion, etc. is obtained, so as to adjust the navigation path of the vehicle in time to avoid entering the area with poor signal reception.

[0043] Through the above process, the vehicle realizes precise positioning. Only when the vehicle can realize precise positioning, the accuracy of the relative position information between the calculated comfort influence object and the vehicle position information can be guaranteed. Therefore, the adjustment of the air conditioning system, seat function and / or steering wheel function according to the relative position information can meet the actual needs of the user, adapt to the current driving scene of the user, and make the user obtain high comfort experience. At the same time, realizing the precise positioning of the vehicle also helps to realize precise navigation, thereby providing the user with a smoother travel experience.

[0044] Step 102, adjusting the control parameters of the air conditioning system and / or auxiliary comfort system according to the relative position information and influence attribute.

[0045] The influence attribute here refers to the change trend of the environmental parameters in the vehicle cabin caused by the comfort influence object, for example, the sun in winter can cause the temperature in the vehicle cabin to rise significantly when it shines on the vehicle cabin. When adjusting the control parameters of the air conditioning system and / or auxiliary comfort system, the influence attribute is considered to ensure that the adjusted control parameters can provide the user with high comfort.

[0046] After obtaining the relative position information between the vehicle and the comfort influencing object, for example, the sun, the influence range or degree of the comfort influencing object on the vehicle can be determined according to the relative position information. For example, when the comfort influencing object is the sun, the specific part of the vehicle, such as the front windshield, side window, etc., on which the sunlight is irradiated is determined, which provides a basis for subsequent adjustment of the air conditioning system and / or auxiliary comfort system. In an example, this determination process can be achieved by analyzing data from various sensors. The vehicle is equipped with multiple temperature and light sensors distributed at different positions in the cabin, such as the instrument panel, seat, etc., for detecting the actual temperature and light intensity in each area of the cabin, so as to evaluate the degree of sunlight influence on each area of the cabin. Changes in the relative position information result in changes in the influence of the comfort influencing object on the vehicle, which can also be used as a basis for subsequent adjustment of the air conditioning system and / or auxiliary comfort system, so that the adjusted state of the air conditioning system and / or auxiliary comfort system can automatically adapt to the current influence degree or range of the comfort influencing object on the vehicle, thereby avoiding the need for manual adjustment by the user during driving, and providing a high-comfort driving experience for the user.

[0047] In an example, the auxiliary comfort system can include seat heating and / or ventilation functions, steering wheel heating and / or ventilation functions, and adjustment of the auxiliary comfort system can also improve the comfort of the user during driving. Of course, the auxiliary comfort system in the present application is not limited to only including these two functions, but is only a general term for description, and can also include other functions or modules that can improve the comfort of the user during driving.

[0048] The adjustment process of the control parameters of the air conditioning system and / or auxiliary comfort system can be described in the following related embodiments.

[0049] Embodiment 1

[0050] In this embodiment, the adjustment process of the control parameters of the air conditioning system according to the relative position information and the influence attribute is mainly described.

[0051] In an implementation manner of this embodiment, before adjusting the air conditioning system, the comfort influencing area of the comfort influencing object on the vehicle cabin is determined according to the change of the relative position information. When the overlap degree between the comfort influencing area and the seat area of the vehicle is higher than a first threshold, the air conditioning system is adjusted to provide high comfort for the driver and passenger. Here, the overlap degree refers to the overlap degree between the comfort influencing area and the seat area of the driver and passenger, that is, the overlap degree between the comfort influencing area and each seat area of the driver and passenger needs to be calculated.

[0052] For example, taking the sun as the comfort influencing object, during the driving of the vehicle, the relative position information of the sun and the vehicle is calculated, and the orientation information of the vehicle is combined to determine the specific area in the vehicle cabin, such as the seat area, the center console area, etc., to which the sunlight is irradiated. The specific area in the vehicle cabin to which the sunlight is irradiated is the comfort influencing area. Then, the degree of overlap between the comfort influencing area and the seat area where the driver and the passenger are located is determined. In one example, this process can be implemented by a monitoring device installed in the vehicle cabin, and the monitoring device can also be used to determine whether there is a user on the seat area. By identifying the image or video stream data collected by the monitoring device, the degree of overlap between the comfort influencing area and the seat area is determined. When the degree of overlap is higher than a first threshold, for example, when the degree of overlap accounts for 70% of the seat area, it is considered that the control parameters of the air conditioning system need to be adjusted at this time. This process can avoid invalid adjustment of the air conditioning system when the influence of the comfort influencing object on the seat area of the vehicle is low, improve the adjustment efficiency of the air conditioning system, and make each adjustment of the air conditioning system contribute to improving the user comfort experience.

[0053] Further, when adjusting the control parameters of the air conditioning system, the air outlet angle, air outlet volume, air outlet speed, refrigeration / heating power, etc. of the air conditioning system can be adjusted, which not only avoids manual adjustment by the user, but also enables the adjusted air conditioning system to adapt to the current influence of the comfort influencing object on the user in the vehicle cabin, thereby providing the user with a high comfort experience.

[0054] In one implementation of the embodiment, when it is determined that the air conditioning system needs to be adjusted, it is determined whether the seat area where the comfort influencing object has an influence has a corresponding independent air outlet. If there is, only the air outlet angle and / or air outlet volume of the independent air outlet can be adjusted, thereby realizing the partition adjustment of the air conditioning system. In this process, by adjusting the air outlet angle and / or air outlet volume of the independent air outlet of the vehicle seat area, on the one hand, the comfort experience of the user corresponding to the independent air outlet can be improved, and the partition adjustment can be realized. On the other hand, the users in other seat areas can also be prevented from being affected by the adjustment of the air conditioning system, meeting the needs of all users in the vehicle. At the same time, the partition adjustment scheme is also helpful for energy saving of the air conditioning system. Only the independent air outlet corresponding to the vehicle seat area with high degree of overlap needs to be adjusted, and the overall adjustment of the air conditioning system is not needed.

[0055] Further, in the implementation of the partition adjustment, the temperature sensor installed in the vehicle cabin can also be used to determine the regional environment temperature of the seat area corresponding to the seat area with the overlap degree higher than the first threshold value, and then determine whether the difference between the change rate of the regional environment temperature and the change rate of the overall environment temperature in the vehicle cabin is greater than a second threshold value. When the difference is greater than the second threshold value, it means that the temperature change of the seat area is faster than the temperature change of the overall vehicle, which is affected by the comfort influence object. At this time, it is necessary to adjust the air volume and / or air angle of the independent air outlet. If the difference between the two change rates is not greater than the second threshold value, it means that the temperature of the seat area does not rise or fall too fast relative to the temperature of the overall vehicle. At this time, the air volume and / or air angle of the independent air outlet can not be adjusted. At the same time, the infrared sensor or the like corresponding to the seat area can also be used to detect the body temperature change of the driver and passenger. When the body temperature change rate is greater than a third threshold value, i.e., when the body temperature of the driver and passenger changes significantly, the air volume and / or air angle of the independent air outlet is adjusted.

[0056] In an implementation manner of the embodiment, when it is determined that the air conditioning system needs to be adjusted, the duration of the high overlap between the comfort influence area and the vehicle seat area is used as one of the factors for adjusting the air conditioning system. The duration of the high overlap between the comfort influence area generated by the comfort influence object in the vehicle cabin and the vehicle seat area is determined by the current driving path of the vehicle, combined with the future position information and orientation information of the vehicle. When the duration is greater than a fourth threshold value, the air conditioning system is adjusted, thereby ensuring the effectiveness of each adjustment of the air conditioning system and avoiding frequent adjustment of the air conditioning system, prolonging the service life of the air conditioning system. For example, when the vehicle is at the current position, the overlap between the comfort influence area generated by the sunlight shining on the vehicle co-driver area and the co-driver seat area is 70%. However, during the advancement of the vehicle along the current driving path, the overlap after the sunlight shining on the vehicle co-driver area may decrease to 30%, i.e., the duration of the overlap of 70% is short. At this time, the air conditioning system does not need to be adjusted, thereby avoiding frequent adjustment of the air conditioning system and providing a bad experience for the user.

[0057] Further, before adjusting the control parameter of the air conditioning system, the remaining time to destination on the current driving path of the vehicle needs to be considered, or the remaining time to destination is determined through the navigation system, and then the control parameter of the air conditioning system is adjusted according to the remaining time to destination, the duration of the overlap and the influence attribute. In this way, if the vehicle still has a short time to reach the destination during driving, even if the seat area is illuminated by sunlight, the duration of the sunlight is certainly less than or equal to the remaining time to destination, so there is no need to adjust the air conditioning system at this time. This scheme can avoid adjusting the air conditioning when approaching the destination, which helps to save energy of the air conditioning system and also makes the user feel more intelligent.

[0058] Embodiment 2

[0059] This embodiment is based on embodiment 1, and the judgment process of whether the air conditioning system needs to be adjusted is replaced, that is, this embodiment provides an alternative scheme for judging whether the air conditioning system needs to be adjusted according to the overlap between the comfort influence area and the seat area.

[0060] As the vehicle in this embodiment, it is equipped with multiple temperature sensors and multiple light sensors, which are installed in different areas of the vehicle cabin, such as the steering wheel area, the seat area, the center console area, etc., for detecting the actual temperature and light intensity in each area of the vehicle cabin. Therefore, the vehicle controller or the air conditioning controller can determine the actual temperature and light intensity in each area of the vehicle cabin by collecting the data of these sensors, so that the air conditioning system can be adjusted when the actual temperature in a certain area is higher / lower than the preset temperature threshold, and / or the light intensity in a certain area is higher / lower than the preset intensity threshold. For example, the actual temperature in the vehicle co-driver area collected by the temperature sensor installed in the co-driver area is lower than the preset temperature threshold, at this time, the user in the co-driver area feels low temperature, then the air conditioning system can be adjusted to blow warm air to increase the temperature in the co-driver area, so that the user feels the temperature rising, and the user's riding comfort is improved.

[0061] In the process, the comfortable temperature interval can also be introduced as the basis for adjusting the air conditioning system. During the driving of the vehicle, the temperature change in the vehicle cabin is monitored in real time by the temperature sensor, and it is determined whether the current temperature is in the comfortable temperature interval. If it is, the air conditioning system can not be adjusted. If it is not, the temperature in the vehicle cabin can be changed to the comfortable temperature interval by adjusting the control parameters of the air conditioning system, so that the user can always obtain high comfort of the air conditioning during driving. It should be noted that although the temperature sensor is arranged in different regions of the vehicle cabin, the temperature difference between different regions in the vehicle cabin during driving, especially when the air conditioning system is started, is generally not large. Therefore, when determining whether the temperature is in the comfortable temperature interval, the temperature value used can be the temperature collected by the temperature sensor in a region, or the average of all temperatures collected by all temperature sensors in the vehicle cabin.

[0062] In the embodiment, the air conditioning system can also be controlled in different regions. Specifically, when the temperature sensor collects a temperature in a region that is higher / lower than the preset temperature threshold, and / or the light sensor collects a light intensity in a region that is higher / lower than the preset intensity threshold, the air outlet speed, air outlet volume, etc. of the independent air outlet corresponding to the region can be adjusted. For example, if the light sensor detects that a region is directly exposed to strong sunlight, the air outlet of the air conditioning system corresponding to the region is adjusted to increase the cold air output. Conversely, the backlight surface appropriately reduces the cold air supply to avoid excessive cooling. By adjusting the air conditioning system in different regions, the comfort of the driver and passenger is improved, unnecessary energy consumption is reduced, and the overall efficiency of the air conditioning system is improved.

[0063] In one example, if the light sensor detects that the light intensity in a region is too high, the sun visor or other auxiliary equipment can also be started to further reduce the heat caused by direct sunlight and assist the user to obtain a high comfort experience.

[0064] In the adjustment of the air conditioning system in this embodiment, since the adjustment is based on the data collected by the illumination sensor and / or the temperature sensor, the data collected by the two sensors can also be used to feed back the adjustment process as the result of the adjustment, so that the final adjustment result of the air conditioning system can better meet the comfort needs of the user. Specifically, after the adjustment of the air conditioning system is completed, the temperature data after the adjustment can be collected by the temperature sensor, and whether the temperature in the cabin is in the comfortable temperature range can be determined according to the change or trend of the temperature data. The comfortable temperature range can be the comfortable temperature range set by the user in advance, or the temperature range set by default by the system, and the user can feel higher comfort in the comfortable temperature range. The air conditioning system is fine-tuned and optimized again according to the collected temperature value. Of course, the user can also check the current air conditioning state or the current temperature value through the vehicle display screen, and even manually intervene in part of the settings to achieve more optimized adjustment of the air conditioning system.

[0065] Embodiment 3

[0066] In this embodiment, the control parameters of the air conditioning system include the on state of the air conditioning system, the on parameters such as the air outlet speed, the air outlet volume, the cooling / heating parameters, and the off state of the air conditioning system, and the auxiliary comfort system includes the steering wheel heating and / or ventilation function and the seat heating and / or ventilation function, which can be referred to as the steering wheel function and the seat function hereinafter.

[0067] After the adjustment of the air conditioning system is completed, the comfort influence parameter in the cockpit is monitored, and the comfort influence parameter is preferably temperature, which can be monitored by a temperature sensor. According to the change of the comfort influence parameter, the control parameter of the auxiliary comfort system is adjusted, that is, the seat function and / or the steering wheel function are adjusted, the linkage of the air conditioner and the steering wheel is realized and / or the linkage of the air conditioner and the seat is realized, so that the auxiliary comfort system and the air conditioning system are adapted to each other, so that the user can obtain a high comfort experience. For example, when the temperature sensor detects that the temperature in the cockpit is too low, the air conditioning system is adjusted to blow warm air, or even increase the air volume or air speed of the warm air, so that the temperature in the cockpit rises. At this time, according to the rising trend of the temperature, the steering wheel heating function or the seat heating function can be adjusted to avoid the user from feeling that the steering wheel is too cold or the seat is too cold. The process is significantly different from the traditional air conditioning and seat linkage strategy. In the traditional linkage strategy, when the temperature of the air conditioning system rises, the seat opens the ventilation function, and when the temperature of the air conditioning system decreases, the seat opens the heating function. In the present embodiment, when the temperature in the cockpit is detected to be low, the temperature of the air conditioning system is adjusted to increase the temperature in the cockpit, and the heating function of the seat is started instead of the ventilation function, realizing a more intelligent linkage strategy and meeting the user's high comfort experience demand.

[0068] The linkage of the air conditioner and the steering wheel and the linkage of the air conditioner and the seat will be described below.

[0069] For the linkage of the air conditioning system and the steering wheel heating / ventilation function, the present embodiment solves the drawbacks of the lack of air conditioning and steering wheel linkage strategy in the prior art. In the prior art, when the user feels that the steering wheel is cold, the steering wheel heating function is turned on, and when the user feels that the steering wheel is hot, the heating function is turned off. The user experience is poor, and the present embodiment can automatically adjust the control parameter of the steering wheel heating / ventilation function according to the linkage strategy of the air conditioner and the steering wheel, avoid the user from manually adjusting frequently, and realize more efficient and more humanized temperature management of the steering wheel.

[0070] The linkage control of the steering wheel heating / ventilation function and the air conditioning system in the present embodiment aims to improve the comfort experience of the driver and the passenger, especially in cold weather conditions. Through the intelligent linkage strategy, the steering wheel heating / ventilation function is integrated with the temperature in the cockpit, realizing more efficient and more humanized temperature management. The following is an implementation scheme:

[0071] 1) Intelligent sensing and prediction: The vehicle cockpit is equipped with multiple sensors, including temperature sensors, humidity sensors, and human infrared sensors, which can monitor the temperature, humidity, and presence of the driver and passenger in the cockpit in real time.

[0072] 2) Personalized temperature settings: The driver can set personal preferences through the central screen or mobile app, including the temperature of the steering wheel heating, heating time, and whether to link with the air conditioning system. The heating intensity of the steering wheel and the temperature of the air conditioning system are automatically adjusted according to the driver's preferences, achieving personalized comfort experience.

[0073] 3) Linkage control logic: When the temperature sensor detects that the ambient temperature in the cockpit is low, the steering wheel heating function is automatically started. At the same time, according to the temperature change in the cockpit, the heating or cooling of the air conditioning system is automatically adjusted to keep the temperature in the driver's cabin within the preset comfort temperature range. Of course, when the ambient temperature in the cockpit is low, the heating of the air conditioning system can be adjusted first, and then the steering wheel heating function can be intelligently started according to the temperature change in the cockpit. In addition, the embodiment can also automatically adjust the heating intensity of the steering wheel according to the physiological response of the driver, such as through heart rate monitoring, to ensure that the driver drives in a comfortable state.

[0074] 4) Energy saving optimization: In order to improve energy efficiency, the system uses intelligent algorithms to intelligently adjust the start and stop time of the steering wheel heating and air conditioning according to the driver's estimated driving time and arrival time at the destination, avoiding excessive heating or cooling, thereby saving energy.

[0075] 5) Safety and health considerations: The embodiment also has safety mechanisms such as steering wheel overheating protection to prevent the steering wheel from overheating and causing harm or poor experience to the user. At the same time, considering the health of the driver, the heating time of the steering wheel can also be automatically controlled to avoid the adverse effects of long-term high-temperature heating on the driver's skin.

[0076] Through this intelligent air conditioning and steering wheel linkage strategy, not only can the driver's driving comfort in cold conditions be improved, but also the user can obtain a high comfort experience, and the energy can be effectively saved and the driving safety can be improved.

[0077] For the linkage of the air conditioning system and the seat heating / ventilation function, the embodiment solves the problem of the existing air conditioning and seat linkage strategy (the user adjusts the temperature, the seat starts the ventilation function, the user adjusts the temperature, the seat starts the heating function), which is unrelated to user comfort. For example, in cold winter, after the user adjusts the air conditioning temperature, the seat will start the seat ventilation function, causing the body to be cool, and the user's comfort experience will decrease, resulting in low usage rate of this linkage strategy. In the embodiment, the starting demand of the seat heating / ventilation function can be intelligently judged according to the temperature change in the cockpit, the intelligent linkage of the air conditioning and the seat is realized, and the control parameters or parameters of the two are adapted to each other to improve the user's comfort experience.

[0078] The air conditioning and seat linkage strategy in this embodiment is an intelligent design aimed at improving the comfort experience of the driver and passengers. The core of this strategy is to intelligently adjust the operation of the seat heating / ventilation and air conditioning system by monitoring the ambient temperature and the body temperature of the driver and passengers in real time, in order to achieve optimal thermal comfort. Here is a possible linkage strategy:

[0079] 1) Ambient temperature monitoring: Real-time monitoring of the ambient temperature inside the vehicle through temperature sensors placed in different areas of the cabin, and also obtaining the temperature outside the vehicle through weather data as a reference.

[0080] 2) Body temperature monitoring: On some high-end vehicle models, the body temperature of the driver and passengers can also be monitored through infrared sensors and other technologies to more accurately adjust the temperature inside the vehicle.

[0081] 3) Intelligent judgment and linkage adjustment: When the temperature inside the vehicle is below the lower limit of the preset comfort temperature range, start the seat heating function, and at the same time, adjust the air conditioning system to the heating mode to quickly raise the temperature inside the vehicle; when the temperature inside the vehicle exceeds the upper limit of the preset comfort temperature range, turn off the seat heating function or start the seat ventilation function, and turn on the air conditioning cooling mode to lower the temperature inside the vehicle. Of course, this process can also be, when the ambient temperature in the cabin is below the lower limit of the preset comfort temperature range, first adjust the heating of the air conditioning system, and then intelligently start the seat heating function according to the temperature change in the cabin; when the ambient temperature in the cabin is higher than the upper limit of the preset comfort temperature range, first adjust the cooling of the air conditioning system, and then intelligently start the seat ventilation function according to the temperature change in the cabin.

[0082] Further, when the temperature inside the vehicle is at or close to the comfort temperature range, the seat heating / ventilation function or the air conditioning air volume can be adjusted according to the slight changes in the body temperature of the driver and passengers to keep the temperature stable within the comfort temperature range.

[0083] 4) Personalized settings: This embodiment can allow the driver and passengers to set the aforementioned comfort temperature range, seat heating / ventilation intensity, etc. according to personal preferences through an easy-to-use control panel or terminal APP, and save the user's personal preference configuration file. The next time the vehicle is started, the file settings are automatically restored to improve the convenience of use and meet the needs of different people.

[0084] 5) Energy saving optimization: The linkage strategy of air conditioning and seat also includes an energy saving mode, that is, when the ideal thermal comfort is achieved, such as when the temperature inside the vehicle is maintained within the preset comfort temperature range, the air conditioning system or the seat system can automatically adjust to the lowest energy consumption state to avoid excessive heating or cooling causing energy waste.

[0085] By means of the linkage strategy between the seat and the air conditioner based on thermal comfort, the comfort experience of the driver and the passenger can be improved significantly, and the energy saving and emission reduction can be achieved to some extent.

[0086] That is, the linkage strategy between the air conditioner and the steering wheel and / or the linkage strategy between the air conditioner and the seat is realized in the embodiment, and the adjusted seat function and / or the steering wheel function can be adapted to the control parameter of the air conditioner system to meet the actual needs of the user, so that the problem of poor user experience and low usage rate of the linkage strategy caused by mechanical adjustment in the traditional linkage scheme between the air conditioner and the seat is avoided, the linkage adjustment is realized intelligently, and the comfort experience of the user is improved significantly.

[0087] In addition, a communication module can be provided in the linkage process between the air conditioner system and the auxiliary comfort system in the embodiment, so that the information or data between the two can be interacted in real time, the two can work synchronously, and the linkage strategy between the air conditioner system and the auxiliary comfort system can be executed stably. In addition, a user-friendly control panel can be provided on the vehicle-mounted device, or a simple APP can be provided on the terminal device, so that the user can easily set and adjust the linkage parameters of the steering wheel or the seat and the air conditioner, and various user scenarios can be met.

[0088] Embodiment 4

[0089] In the embodiment, the adjustment process of the auxiliary comfort system according to the relative position information and the influence attribute is mainly described. The process can be independent of the adjustment process of the air conditioner system, and is suitable for the scene in which the air conditioner system does not need to be adjusted or the air conditioner system is not linked with the auxiliary comfort system.

[0090] Specifically, after obtaining the relative position information between the vehicle and the comfort influencing object, the generated comfort influencing area of the comfort influencing object in the vehicle cabin is determined according to the relative position information or the change of the relative position information, such as the relative position between the vehicle and the sun, in combination with the orientation information of the vehicle. The process can be referred to the related description in Embodiment 1, which will not be repeated here. Then, it is determined whether the comfort influencing area contains the steering wheel area or the seat area, for example, whether the sunlight shines on the steering wheel or the seat. The process can be realized by a monitoring device in the cabin. The video stream data or image data collected by the monitoring device is used to identify the content contained in the comfort influencing area. When the comfort influencing area contains the steering wheel area and / or the seat area, the control parameter of the steering wheel ventilation / heating function is adjusted, and / or the control parameter of the seat ventilation / heating function is adjusted. In an example, the comfort influencing area containing the steering wheel area or the seat area can also be realized by the concept of overlap degree, that is, the overlap degree between the comfort influencing area and the seat area where the driver or passenger is located is calculated. When the overlap degree is higher than a first threshold, it is considered that the comfort influencing area contains the seat area. The overlap degree between the comfort influencing area and the steering wheel is calculated. When the overlap degree is higher than a fifth threshold, it is considered that the comfort influencing area contains the steering wheel area. It should be noted that the steering wheel area here can refer to the steering wheel. At this time, the overlap degree is the ratio of the area where the sunlight shines on the steering wheel to the entire circular steering wheel.

[0091] For example, taking the sun as the comfort influencing object, according to the relative position between the sun and the vehicle, in combination with the orientation information of the vehicle, the illumination area of the sunlight in the vehicle cabin is determined. It is determined whether the illumination area contains the steering wheel. If it contains, the steering wheel ventilation function is started to avoid the driver's hand from sweating under the illumination of the sunlight, which may cause a driving safety hazard. At the same time, the steering wheel ventilation function can also cool the steering wheel area, so that the user can drive in high comfort.

[0092] For example, taking the buildings on both sides of the road as the comfort influencing object, the shadow generated by the buildings can completely or partially cover the vehicle cabin area. The relative position between the buildings and the sun is determined through the position information of the buildings on the current driving map of the vehicle, so as to obtain the shadow area generated by the buildings. Then, according to the position information and the orientation information of the vehicle, the comfort influencing area of the shadow area to the vehicle cabin is determined. If the comfort influencing area contains the seat area of the vehicle, it is assumed that it is in the cold winter. At this time, the shadow generated by the buildings acting on the seat area of the vehicle can reduce the temperature of the seat area. At this time, the heating function of the seat can be started to increase the temperature of the seat area, so as to improve the driving comfort experience of the user.

[0093] Of course, in this embodiment, the data collected by the temperature sensors and / or light sensors installed in different areas of the cockpit can also be used to determine whether the steering wheel function and / or the seat function need to be adjusted. For example, taking the sun as the comfort influencing object and the hot summer as the vehicle driving scenario, when the light sensor installed in the steering wheel area or the seat area detects that the light intensity in the steering wheel area or the seat area is high, the ventilation function of the steering wheel or the seat can be started to avoid the high temperature in the steering wheel area or the seat area caused by sunlight, which makes the user feel uncomfortable. By starting the ventilation function, the temperature in the steering wheel area or the seat area can be reduced, making the user feel cool and improving the user's driving comfort experience.

[0094] In a possible implementation of the present application, the area environment temperature of the seat area can also be detected by the aforementioned temperature sensor, and the overall environment temperature can be determined by the average temperature detected by all temperature sensors in the vehicle. Then, it is determined whether the area environment temperature or the overall environment temperature is within a preset comfortable temperature range. If not, the control parameters of the auxiliary comfort system are adjusted according to the user's comfort preference and influencing attribute for the auxiliary comfort system. In this implementation, on the one hand, the environment temperature is used to determine whether adjustment is needed, and on the other hand, the user's comfort preference is highlighted. The comfort preference here is for the steering wheel / seat and can be obtained from the user's historical operation or setting data for the steering wheel / seat. That is, when adjusting the control parameters of the auxiliary comfort system, the user's preference data is considered, so that the adjusted steering wheel / seat can better meet the user's comfort needs. In addition, the aforementioned comfortable temperature range refers to the comfortable range of the environment temperature in the vehicle cockpit, which can be obtained from the user's personal preference data set by the user on the vehicle central control screen or mobile APP, for example, setting the environment temperature in the cockpit, to meet the user's personalized setting needs. Therefore, when adjusting the auxiliary comfort system or the air conditioning system, the user's personal preference data can be referred to to adjust the temperature in the cockpit to the comfortable temperature range set by the user, so that the user can have a high comfort experience. Of course, the aforementioned preset comfortable temperature range can also be obtained from the vehicle historical driving record data, for example, the temperature range in the cockpit when the user last drove the vehicle, which is used as the comfortable temperature range. This case is preferably applicable to the situation where the user does not set personal preference data, that is, when the user does not set the comfortable temperature range, the cockpit temperature range when the user last drove the vehicle is used as the comfortable temperature range. By adjusting the air conditioning system or the auxiliary comfort system, the temperature in the vehicle is within the comfortable temperature range, so that the user can have a high comfort experience. At the same time, the comfortable temperature range is also the basis for adjusting the air conditioning system and the auxiliary comfort system, for example, when the temperature in the cockpit is not within the temperature range, the control parameters of the air conditioning system and / or the auxiliary comfort system need to be adjusted.

[0095] Therefore, the embodiment realizes the adjustment of the seat function and / or the steering wheel function according to the relative position information, that is, even without adjusting the air conditioning system, the linkage adjustment of the seat function and / or the steering wheel function can be realized in the embodiment, the manual adjustment of the user is avoided, and the user comfort preference is considered in the adjustment process, so that the adjusted seat function and / or steering wheel function can meet the user demand and improve the user comfort experience.

[0096] Embodiment 5

[0097] After the adjustment of the control parameters of the air conditioning system and / or the auxiliary comfort system is completed through any one of the above embodiments or a combination of several embodiments, the environmental temperature in the vehicle cabin is in the aforementioned preset comfortable temperature interval. In order to save energy consumption, the power consumption of the air conditioning system and the auxiliary comfort system is preferably adjusted to the minimum, but the minimum adjustment is on the premise that the temperature in the cabin cannot be lower than the comfortable temperature interval, so as to avoid affecting the comfort experience of the user.

[0098] In a possible implementation manner of the embodiment, after the adjustment is completed, that is, after the environmental temperature in the cabin is in the comfortable temperature interval, the human body temperature of the driver can be detected through the infrared sensor installed in the vehicle. It should be noted that the change in the body temperature of the driver is preferably focused on. When the human body temperature of the driver changes, the control parameters of the air conditioning system and / or the auxiliary comfort system are fine-tuned according to the change trend, so that the driver can obtain a higher comfort experience on the premise that all the people in the cabin feel comfortable. For example, after the adjustment of the air conditioning system and / or the auxiliary comfort system is completed, it is detected that the temperature of the human body of the driver decreases by 0.5-1℃. At this time, the control parameters of the auxiliary comfort system can be fine-tuned, for example, the temperature of the seat heating is increased by 1-2℃, so that the driver can obtain a better experience. However, at this time, the environmental temperature in the vehicle cabin is still in the preset comfortable temperature interval, and other people in the cabin can also feel a high comfort experience.

[0099] In a possible implementation manner of the present application, before each of the above embodiments is executed, a pre-judgment step can be added, so that the process of adjusting the control parameters of the air conditioning system and / or the auxiliary comfort system is meaningful or necessary. Specifically, before the adjustment, the destination arrival remaining time of the current trip can be predicted according to the current driving path of the vehicle. The destination arrival remaining time can also be directly obtained from the navigation information of the vehicle. If the destination arrival remaining time is too short, the air conditioning system and / or the auxiliary comfort system does not need to be adjusted. If it still takes a long time to reach the destination, the adjustment process can be normally executed, and the control parameters are adjusted according to the relative position information and the influence attribute.

[0100] Further, after the adjustment is completed, the maintenance time of the control parameter can also be adjusted according to the arrival time of the destination, for example, the air conditioning system or the auxiliary comfort system can be turned off in advance when the vehicle is close to the destination, so as to achieve the energy saving effect.
