Description

Technical Field

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

[0002] In order to improve the comfort experience of the driver and passengers, some vehicles provide functions such as steering wheel heating and / or ventilation, and seat heating and / or ventilation. For example, in cold winter, users can turn on the steering wheel heating function to increase the temperature of the steering wheel, avoiding the discomfort caused by low temperature when the driver holds the steering wheel; and users can also start the seat heating function to increase the seat temperature, thereby enhancing the user's riding experience.

[0003] Currently, the ventilation and heating functions of the steering wheel / seat are realized based on the active control of the user, and cannot be automatically started, turned off, or adjusted in terms of the opening gear according to the personalized needs of the user, with low intelligence. At the same time, the sun shining into the vehicle cockpit will affect the body sensations of the drivers and passengers in different seats. For example, the temperature difference between the cockpits of vehicles under the shade of a tree and those exposed to the sun in summer may exceed 10°C. The air conditioning system is not associated with the steering wheel / seat ventilation and heating, and does not consider the impact of comfort-affecting objects in the external environment on the in-vehicle comfort, which may cause poor comfort for the drivers and passengers or waste of vehicle energy consumption. Summary of the Invention

[0004] In view of the above problems, the present application provides a vehicle control method, device, and vehicle that 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 includes an air conditioning system and an auxiliary comfort system, the auxiliary comfort system includes at least one of seat ventilation, seat heating, steering wheel ventilation, and steering wheel heating, and the method includes: obtaining the position information and influence attributes of a comfort-affecting object, the comfort-affecting object being capable of changing the environmental parameters in the vehicle cockpit, and the influence attribute being used to indicate the change trend of the environmental parameters; calculating the relative position information between the vehicle and the comfort-affecting object in response to the position information and / or orientation information of the vehicle; and adjusting the control parameters of the air conditioning system and / or the control parameters of the auxiliary comfort system based on the relative position information and the influence attribute.

[0006] In this application, the relative position information between the vehicle and the comfort influence object is determined through the position information and / or the orientation information of the vehicle. Then, based on this relative position information and the influence attributes of the comfort influence object, the control parameters of the vehicle's air conditioning system are adjusted. On the one hand, the automatic adjustment of the air conditioning system is realized, avoiding the drawback that users need to frequently manually adjust the air conditioning system due to changes in temperature perception. On the other hand, when adjusting the air conditioning system according to the relative position information between the vehicle and the comfort influence object, the influence attributes of the comfort influence object are also comprehensively considered, enabling the adjusted air conditioning system to adapt to the relative position information, so that the vehicle occupants can obtain a high level of air conditioning comfort and enhance the user's comfort experience. At the same time, the auxiliary comfort system can also be adjusted according to the relative position information between the vehicle and the comfort influence object, that is, the seat function and / or the steering wheel function are adjusted, and the influence attributes of the comfort influence object are also considered during the adjustment. This can not only realize the automatic adjustment of the seat function and / or the steering wheel function, improve the intelligence level of the vehicle, and enable users to obtain a high level of driving comfort experience, but also ensure that the adjusted auxiliary comfort system can adapt to the current position information of the vehicle, avoiding the situation where the user's driving experience decreases due to the influence of the comfort influence object. Furthermore, the adjustment of the seat function and / or the steering wheel function in this application can also be adaptively adjusted according to the control parameters of the adjusted air conditioning system, so as to realize the linkage strategy between the air conditioning and the seat and / or the linkage strategy between the air conditioning and the steering wheel, avoiding the user from manually starting or closing the seat function and / or the steering wheel function, enhancing the user's driving comfort experience, and the solution of adjusting the seat function and / or the steering wheel function according to the control parameters of the air conditioning system also realizes the intelligent automatic adjustment of the seat function and / or the steering wheel function, and enables the adjusted seat function and / or the steering wheel function to effectively adapt to the current user needs, significantly enhancing the user's comfort experience.

[0007] In a possible implementation manner of this application, adjusting the control parameters of the air conditioning system according to the relative position information and the influence attributes includes: determining, according to the relative position information, the comfort influence area of the comfort influence object on the vehicle cockpit; respectively calculating the overlap degrees between the comfort influence area and each vehicle seat area where there are vehicle occupants; when at least one overlap degree is higher than a first threshold, adjusting the control parameters of the air conditioning system according to the influence attributes, and the control parameters of the air conditioning system include at least one of an air outlet angle, an air volume, and a heating / cooling parameter.

[0008] In this embodiment, the control parameters of the air conditioning system are adjusted according to the overlap degree between the comfort influence object and the vehicle seat area where there is a driver or passenger. Only when the overlap degree between the two is higher than the first threshold, that is, when the overlap degree between the two is high, which means that the comfort influence object has a great impact on the users sitting in the vehicle seat area at this time, the air conditioning system is adjusted, so as to achieve the effective adjustment of the air conditioning system. For example, when the comfort influence object is the sun, a high overlap degree between the comfort influence object and a vehicle seat area where there is a driver or passenger means that the sun shines on a large range of users sitting in this seat area. At this time, adjusting the control parameters of the air conditioning system can effectively improve the comfort experience of the users. This process can also avoid the ineffective adjustment of the air conditioner when the influence degree of the comfort influence object on the vehicle seat area is low, improve the adjustment efficiency of the air conditioning system, and make each adjustment of the air conditioning system contribute to improving the comfort experience of the users. Moreover, when adjusting the air conditioning system, the adjustment content is at least one of the air outlet angle, air volume, and heating / cooling parameters of the air conditioning system. Through the adjustment of these parameters, not only the manual adjustment by the users is avoided, but also the air conditioning comfort of the corresponding users can be significantly improved.

[0009] In a possible implementation manner of the present application, the air conditioning system is provided with independent air outlets, and the independent air outlets can blow air toward the vehicle seat area where there is a driver or passenger. The method further includes: for the vehicle seat area with the overlap degree higher than the first threshold, obtaining the regional ambient temperature detected by its corresponding temperature sensor, and / or obtaining the body temperature of its corresponding driver or passenger; when the difference between the change rate of the regional ambient temperature and the change rate of the overall cockpit ambient temperature is greater than the second threshold, and / or when the change rate corresponding to the body temperature is greater than the third threshold, adjusting the air outlet angle and / or air volume of the independent air outlet of the air conditioning system according to the influence attribute.

[0010] In this embodiment, by adjusting the air outlet angle and / or air volume of the independent air outlets in the vehicle seat area with an overlap degree higher than the first threshold, the zonal adjustment of the air conditioning system is achieved. On the one hand, it can improve the comfort experience of the users corresponding to the independent air outlets. On the other hand, it can also prevent the users in other seat areas 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 zonal adjustment solution also helps to save energy in the air conditioning system. Only the independent air outlets corresponding to the vehicle seat areas with a high overlap degree need to be adjusted, without the need for an overall adjustment of the air conditioning system. Moreover, during the zonal adjustment, the ambient temperature of the area is first detected by the temperature sensor corresponding to the seat area, and the body temperature of the occupants in the seat area is monitored by the infrared sensor corresponding to the seat area. When the difference between the change rate of the ambient temperature of the area and the change rate of the overall ambient temperature in the vehicle cockpit is greater than the second threshold, or the change rate corresponding to the body temperature is greater than the third threshold, the independent air outlets will be adjusted. Thus, the effectiveness of the adjustment of the independent air outlet parameters can be ensured, and the zonal control of the air conditioning system can be realized.

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

[0012] In this embodiment, taking the duration of the high overlap between the comfort influence area and the vehicle seat area as one of the considerations for adjusting the air conditioning system, and adjusting the air conditioning system only when the duration is greater than the fourth threshold can ensure the effectiveness of each adjustment of the air conditioning system, avoid frequent adjustment of the air conditioning system, and extend the service life of the air conditioning system.

[0013] In an implementation manner of the present application, the method further includes: obtaining the remaining duration until the destination is reached in the vehicle navigation information, and adjusting the control parameters of the air conditioning system and / or the auxiliary comfort system based on the relative position information or duration, the remaining duration until the destination is reached, and the influence attribute.

[0014] In this implementation manner, after determining the duration during which the overlap between the comfort influence area and the vehicle seat area is higher than the first threshold, the remaining duration until the destination is reached in the current driving path of the vehicle or the vehicle navigation information is also comprehensively considered, which can avoid unnecessary adjustment of the air conditioner when the remaining duration until the destination is reached is short. At the same time, taking the remaining duration until the destination is reached on the current driving path of the vehicle as a judgment condition for whether to adjust the air conditioning system and / or the auxiliary comfort system can avoid adjusting the air conditioning system and / or the auxiliary comfort system when the user is about to reach the destination, thus avoiding the drawback of ineffective adjustment, ensuring the effectiveness of the adjustment, and also saving energy.

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

[0016] In this embodiment, the comfort influence area determined through the relative position information between the vehicle and the comfort influence object is used as a judgment factor for adjusting the seat function and / or the steering wheel function. That is, when the overlap degree between the comfort influence area and the auxiliary comfort system is higher than the threshold, the auxiliary comfort system is adjusted, realizing the adjustment of the seat function and / or the steering wheel function based on 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 this embodiment, avoiding manual adjustment by the user, and enabling the adjusted seat function and / or steering wheel function to effectively improve the user's comfort experience.

[0017] In a possible implementation manner of the present application, adjusting the control parameters of the auxiliary comfort system according to the relative position information and the influence attribute includes: determining whether the regional ambient temperature or the overall ambient temperature is within a preset comfortable temperature range, which is obtained through user settings or data related to the environmental parameters in the cockpit in the user's historical driving records; if not, then adjusting the control parameters of the auxiliary comfort system according to the user's comfort preference and the influence attribute, and the user's comfort preference is 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 achieved based on the ambient temperature in the vehicle cockpit. After the air conditioning system is adjusted, by monitoring the regional ambient temperature or the overall ambient temperature in the cockpit and determining whether the temperature is within a preset comfortable temperature range, if not, the seat function and / or the steering wheel function are adjusted, realizing the linkage between the air conditioner and the steering wheel and / or the linkage between the air conditioner and the seat, and enabling the adjusted seat function and / or steering wheel function to be adapted to the influencing factors, meeting the actual needs of the user at present, avoiding the problem of poor user experience caused by mechanical adjustment in the traditional air conditioner and seat linkage scheme, realizing intelligent linkage adjustment, and significantly improving the user's comfort experience. Moreover, the comfortable temperature range in this embodiment can be obtained on the one hand through user settings, and on the other hand from the data related to the cockpit environment in the vehicle's historical driving records. At the same time, when adjusting the control parameters of the auxiliary comfort system, the historical data of the user operating the auxiliary comfort system is also comprehensively considered to make the adjusted auxiliary comfort system better meet the user's comfort requirements.

[0019] In a possible implementation manner of the present application, after the adjustment of the control parameters of the air conditioning system and / or the control parameters of the auxiliary comfort system is completed, the method further includes: determining that the regional 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 adjustment of the control parameters of the air conditioning system and / or the auxiliary comfort system is completed, if the regional ambient temperature and the overall ambient temperature in the vehicle cockpit are within the preset comfortable temperature range, the control parameters of the air conditioning system and / or the auxiliary comfort system can be finely adjusted by continuously monitoring the minute changes in the driver's body temperature detected by an infrared sensor or the like, so that the user can obtain a higher comfort experience, or reduce the vehicle energy consumption for energy-saving purposes.

[0021] An electronic device, the electronic device includes: at least one processor; and a memory communicatively connected to the at least one processor; wherein, the memory stores instructions executable by the at least one processor, and when the instructions are executed by the at least one processor, the at least one processor is enabled to perform: obtaining position information and influence attributes of a comfort influence object, the comfort influence object being capable of changing environmental parameters in a vehicle cockpit, and the influence attributes being used to indicate the change trend of the environmental parameters; in response to the position information and / or orientation information of the vehicle, calculating relative position information between the vehicle and the comfort influence object; and adjusting control parameters of the air conditioning system and / or control parameters of the auxiliary comfort system according to the relative position information and the influence attributes.

[0022] A vehicle, comprising: at least one memory for storing executable program code; a processor for calling and running the executable program code from the at least one memory, so that the vehicle can perform: obtaining position information and influence attributes of a comfort influence object, the comfort influence object being capable of changing environmental parameters in a vehicle cockpit, and the influence attributes being used to indicate the change trend of the environmental parameters; in response to the position information and / or orientation information of the vehicle, calculating relative position information between the vehicle and the comfort influence object; and adjusting control parameters of the air conditioning system and / or control parameters of the auxiliary comfort system according to the relative position information and the influence attributes.

[0023] The above description is only an overview of the technical solution of the present application. In order to be able to understand the technical means of the present application more clearly, it can be implemented according to the content of the specification. And in order to make the above and other purposes, features and advantages of the present application more obvious and understandable, the following specifically gives the specific implementation manners of the present application. Description of the Drawings

[0024] By reading the following detailed description of the preferred embodiments, various other advantages and benefits will become clear to those of ordinary skill in the art. The drawings are only for the purpose of showing the preferred embodiments and are not considered to be a limitation of the present application. And throughout the drawings, the same reference numerals are used to represent the same components. In the drawings:

[0026] Figure 2 Shows a schematic structural diagram of a linkage control device for a vehicle provided by an embodiment of the present application. Detailed Embodiments

[0027] Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present application can be more thoroughly understood and the scope of the present application can be fully conveyed to those skilled in the art.

[0028] The present application provides a linkage control method, device and vehicle for a vehicle, as Figure 1 shown, Figure 1 FIG. is a flowchart of a linkage control method for a vehicle provided by an embodiment of the present application. This method is applicable to the vehicle's vehicle processor or controller, and can also be applicable to the corresponding processor or corresponding controller of the air conditioning system and / or auxiliary comfort system. The specific implementation steps are as follows:

[0029] Step 101, obtain the position information and influence attribute of the comfort influence object.

[0030] During the driving process of the vehicle, the sun, buildings, etc. may affect the environmental parameters in the vehicle cockpit. For example, in the hot summer, after the sun shines on the cockpit, the value of the environmental temperature parameter in the cockpit can rise rapidly, directly affecting the user's comfort experience. In this embodiment, the object that can affect the cockpit environmental parameters is recorded as the comfort influence object during the vehicle driving process. In one example, the comfort influence object preferably includes the sun. Of course, it can also include buildings, trees, etc. on both sides of the vehicle driving road. However, the buildings here are preferably those that can produce shadows covering part or all of the vehicle area. Assuming that at the current moment, the shadow area generated by the sun shining on the building cannot cover the vehicle driving on the road, it is considered that the building has no comfort influence on the vehicle at this time. And different comfort influence objects may have different effects on the environmental parameters in the cockpit due to seasonal and other factors. Therefore, in this embodiment, the concept of influence attribute is used to characterize the influence trend of comfort influence factors on the cockpit environmental parameters.

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

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

[0033] During the driving process of the vehicle, the position information and / or the orientation information will be continuously updated. The position information refers to the current longitude, latitude, altitude and other information of the vehicle, and the orientation information refers to the direction information pointed by the vehicle's head. In one example, the position information of the vehicle can be determined by the vehicle's GPS module; the orientation information of the vehicle can be obtained by the vehicle's inertial measurement unit or electronic compass. Both of these two sensors can provide the angle of the vehicle relative to the magnetic north, so as to obtain 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, its position information is related to the current time. Therefore, by using the current time and the position information and / or the orientation information of the vehicle, the calculation of the relative position information can be realized.

[0035] Specifically, taking the sun as an example of the comfort influence object, when calculating 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. This process can obtain the current time through the Coordinated Universal Time (UTC) provided by the vehicle's GPS module or the vehicle's built-in clock. Then, calculate the position of the sun relative to the earth. Specifically, using a preset astronomical algorithm, such as the calculation formulas of the solar azimuth angle and the solar altitude angle, etc., according to the position information of the vehicle and the obtained current time, calculate the position of the sun relative to the earth. Among them, the solar altitude angle refers to the angle between the sun's rays and the ground plane; the solar azimuth angle refers to the projection direction of the sun on the horizontal plane, usually with the due north as the 0-degree reference and measured in the clockwise direction. It should be noted that the calculation processes of the solar altitude angle and the solar azimuth angle can be realized by existing formulas or existing algorithms, and the embodiments of the present application will not elaborate on this here. Finally, by comparing the azimuth angle and the altitude angle of the sun with the orientation information of the vehicle, the position of the sun relative to the vehicle can be obtained, that is, the relative position information between the sun and the vehicle can be obtained. For example: If the solar azimuth angle is 90 degrees (due east) and the vehicle orientation is 0 degrees (due north), then the sun is on the right side of the vehicle. If the solar altitude angle is low (close to the horizon), it is considered that the sun may be on the horizon in front of or behind the vehicle.

[0036] In a possible implementation manner of the present application, the relative position information is an important basis for subsequently adjusting 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. Accurate or precise vehicle position information directly affects the accuracy of the relative position information between the vehicle and the comfort impact object, and further affects the effectiveness of subsequently adjusting the air conditioning system and / or the auxiliary comfort system, ensuring that the adjusted air conditioning system and / or auxiliary comfort system can bring a high comfort experience to the user. Therefore, how to ensure the accuracy of the vehicle position information and achieve the precise positioning of the vehicle is particularly important.

[0037] The position information of the vehicle is preferably obtained through the GPS module. When the vehicle is driving through mountainous areas, urban canyons, areas with electronic interference and other road conditions, it is easy to have problems such as untimely GPS signal response, and even GPS signal loss may occur, making the vehicle unable to obtain precise position information. To solve this problem, during the driving process of the vehicle, the present application predicts the signal strength and / or signal stability of the GPS signal in the future area to be driven into through the received historical GPS signals, or determines the future area to be driven into by the vehicle through the current driving map of the vehicle, and combines the topographical features of the area to be driven into to predict the signal strength and / or signal stability of the GPS signal. Then, based on the predicted signal strength and / or signal stability of the GPS signal, it is determined whether the vehicle meets the precise positioning conditions in the area to be driven into. In an example, the precise positioning conditions can be set by the signal strength and / or signal stability. For example, by setting the thresholds of the signal strength and / or signal stability, when both are not lower than a certain value, it is considered that the precise positioning conditions are met. It should be noted that the prediction process of the GPS signal can be realized through a machine learning algorithm. By analyzing and learning the reception of historical GPS signals, or learning the GPS signal change situation in a specific area from a large amount of data, the change situation of future GPS signals can be predicted. The specific machine learning process can be realized through existing algorithms, and the present application will not elaborate here.

[0038] Furthermore, if it is determined according to the predicted signal strength and / or signal stability that the vehicle cannot achieve precise positioning in the future area to be driven into, the following means can be used for positioning compensation to achieve the 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 vulnerable to interference, download and store the high-precision map data of this area in advance, including information such as road networks and terrain features, so that when the GPS signal is missing, the vehicle can still navigate based on the stored map data, thereby ensuring that precise position information of the vehicle can be obtained.

[0040] 2) Multi-source positioning fusion: In addition to relying on GPS signals, before the vehicle enters an area with poor signal or vulnerable to interference, the vehicle's auxiliary positioning system can be activated to combine other positioning technologies, such as the GLONASS satellite navigation system, GALILEO satellite navigation system, Beidou satellite navigation system, as well as base station positioning, WIFI positioning, inertial navigation system and other technologies, to improve positioning accuracy and stability through positioning data fusion.

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

[0042] 4) Real-time traffic condition update: Through methods such as vehicle networking and mobile communication networks, real-time traffic condition information is obtained, such as road construction, accidents, traffic jams, etc., so as to timely adjust the vehicle's navigation route and avoid entering areas with poor signals.

[0043] Through the above process, the vehicle achieves precise positioning. Only when the vehicle can achieve precise positioning can the accuracy of the relative position information between the calculated comfort influence object and the vehicle position information be guaranteed. Thus, the adjustment of the air conditioning system, seat function and / or steering wheel function based on this relative position information can meet the actual needs of users, adapt to the user's current driving scenario, and enable users to obtain a high-comfort experience. At the same time, achieving precise positioning of the vehicle also helps to achieve precise navigation, thereby providing users with a smoother travel experience.

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

[0045] The influence attribute here refers to the change trend of the environmental parameters in the vehicle cockpit caused by the comfort influence object. For example, in winter, the sun, when shining on the vehicle cockpit, can significantly increase the temperature in the vehicle cockpit. When adjusting the control parameters of the air conditioning system and / or the auxiliary comfort system, considering this influence attribute can ensure that the adjusted control parameters enable users to obtain high comfort.

[0046] After obtaining the relative position information between the vehicle and a comfort-affecting object such as the sun, it is possible to determine the influence range or degree of the comfort-affecting object on the vehicle based on this relative position information. For example, taking the comfort-affecting object as the sun, it is determined which specific parts of the vehicle, such as the front windshield, side windows, etc., are irradiated by the sunlight, providing a basis for subsequent adjustment of the air conditioning system and / or the auxiliary comfort system. In one example, this determination process can be achieved by analyzing data from various sensors. Multiple temperature and light sensors are equipped inside the vehicle, distributed at different positions in the cockpit such as the instrument panel, seats, etc., for detecting the actual temperature and light intensity in each area of the cockpit, thereby evaluating the degree to which each area in the cockpit is affected by sunlight. The change in the relative position information leads to a change in the influence of the comfort-affecting object on the vehicle, and this change can also be used as a basis for subsequent adjustment of the air conditioning system and / or the auxiliary comfort system, enabling the adjusted state of the air conditioning system and / or the auxiliary comfort system to automatically adapt to the current influence degree or range of the comfort-affecting object on the vehicle, avoiding the drawbacks of manual adjustment by the user during driving and providing a high-comfort driving and riding experience for the user.

[0047] In one example, the auxiliary comfort system can include seat heating and / or ventilation functions, steering wheel heating and / or ventilation functions. By adjusting the auxiliary comfort system, the comfort of the user during driving can also be improved. Of course, the auxiliary comfort system in this application is not limited to only including these two functions. It is just used as a general term for convenience of description and can also include other functions or modules that can improve the driving and riding comfort of the user.

[0048] The process of adjusting the control parameters of the air conditioning system and / or the auxiliary comfort system can refer to the following related embodiments.

[0049] Embodiment 1

[0050] In this embodiment, the process of adjusting the control parameters of the air conditioning system based on the relative position information and influence attributes is mainly described.

[0051] In one implementation manner of this embodiment, before adjusting the air conditioning system, first determine the comfort-influencing area of the comfort-affecting object on the vehicle cockpit according to the change in the relative position information. When the overlap degree between the comfort-influencing area and the vehicle seat area is higher than the first threshold, adjust the air conditioning system to enable the driver and passengers to obtain high comfort. Here, the overlap degree refers to the overlap degree between the comfort-influencing area and the seat area where there are drivers and passengers. That is, when calculating, it is necessary to calculate the overlap degree between the comfort-influencing area and each seat area where there are drivers and passengers.

[0052] Taking the sun as an example of the comfort influence object, during the vehicle driving process, based on the calculated relative position information of the sun and the vehicle and combined with the vehicle's orientation information, it is possible to determine the specific areas in the vehicle cockpit where sunlight shines, such as the seat area, the center console area, etc. The specific area in the vehicle cockpit where sunlight shines here is the comfort influence area. Then, judge the overlap degree between the comfort influence area and each seat area where there are occupants. In one example, this process can be realized by a monitoring device installed in the cockpit, and this monitoring device can also be used to judge whether there is a user sitting on the seat area. By identifying the image or video stream data collected by the monitoring device, the overlap degree between the comfort influence area and the seat area is determined. When the overlap degree is higher than the first threshold, for example, when the overlap degree 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 the ineffective adjustment of the air conditioning system when the influence degree of the comfort influence object on the vehicle seat area 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's comfort experience.

[0053] Furthermore, when adjusting the control parameters of the air conditioning system, parameters such as the air outlet angle, air volume, air outlet speed, refrigeration / heating power 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 influence object on the users in the cockpit, so that the user can obtain a high comfort experience.

[0054] In one implementation manner of this embodiment, when it is determined that the air conditioning system needs to be adjusted, judge whether there is a corresponding independent air outlet in the seat area affected by the comfort influence object. If so, only adjust the air outlet angle and / or air volume of this independent air outlet, thereby realizing the zoning adjustment of the air conditioning system. In this process, by adjusting the air outlet angle and / or air volume of the independent air outlet in the vehicle seat area, on the one hand, it can improve the comfort experience of the user corresponding to the independent air outlet and achieve zoning adjustment, and on the other hand, it can also avoid the influence of the adjustment of the air conditioning system on the users in other seat areas, meeting the needs of all users in the vehicle; at the same time, the zoning adjustment scheme is also helpful for the energy saving of the air conditioning system, only need to adjust the independent air outlet corresponding to the vehicle seat area with a high overlap degree, without the need for overall adjustment of the air conditioning system.

[0055] Further, when implementing partition adjustment, it can also be achieved in combination with the temperature sensors installed in the vehicle cockpit. The ambient temperature of the seat area is determined by the temperature value detected by the temperature sensor corresponding to the seat area with an overlap degree higher than the first threshold. Then, it is judged whether the difference between the change rate of the ambient temperature of this area and the change rate of the overall ambient temperature in the vehicle cockpit is greater than the second threshold. When it is greater, it means that the temperature change in the seat area is faster than that of the whole vehicle, and it is affected by the comfort influence object. At this time, it is necessary to adjust the air volume and / or air outlet angle of the independent air outlet. If the difference between the two change rates is not greater than the second threshold, it means that the temperature of the seat area does not rise or fall too fast relative to the vehicle temperature. At this time, the air volume and / or air outlet angle of the independent air outlet may not be adjusted. At the same time, the infrared sensor and other sensors corresponding to the seat area can also be used to detect the body temperature change of the driver and passengers. When the body temperature change rate is greater than the third threshold, that is, when the body temperature of the driver and passengers changes significantly, the air volume and / or air outlet angle of the independent air outlet is adjusted.

[0056] In an implementation manner of this 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 considerations for adjusting the air conditioning system. By combining the current driving path of the vehicle with the future position information and orientation information of the vehicle, it is judged the duration of the high overlap between the comfort influence area generated by the comfort influence object in the vehicle cockpit and the vehicle seat area. When the duration is greater than the fourth threshold, the air conditioning system is adjusted. This can ensure the effectiveness of each adjustment of the air conditioning system, avoid frequent adjustment of the air conditioning system, and extend the service life of the air conditioning system. For example, when the vehicle is at the current position, the overlap degree between the comfort influence area generated by sunlight shining on the co-pilot area of the vehicle and the co-pilot seat area is 70%. However, during the vehicle's forward movement along the current driving path, the overlap degree may decrease to 30% after sunlight shines on the co-pilot area of the vehicle, that is, the duration of the overlap degree of 70% is short. At this time, there is no need to adjust the air conditioning system, thus avoiding frequent adjustment of the air conditioning system and bringing a bad experience to users.

[0057] Further, before adjusting the control parameters of the air-conditioning system, it is also necessary to consider the remaining time until the vehicle reaches the destination on the current driving route, or determine the remaining time until the destination is reached through the navigation system. Then, based on the remaining time until the destination is reached, the duration of the overlap, and the influence attributes, the control parameters of the air-conditioning system are adjusted. In this way, if the vehicle is about to reach the destination in a short time during driving, even if the seat area is irradiated by sunlight, the duration must be less than or equal to the remaining time until the destination is reached. Then, in fact, there is no need to adjust the air-conditioning system at this time. This solution can avoid adjusting the air-conditioning when approaching the destination, contribute to the energy saving of the air-conditioning system, and at the same time enable users to feel a higher level of intelligence.

[0058] Embodiment 2

[0059] Based on Embodiment 1, this embodiment substitutes the judgment process of whether the air-conditioning system needs to be adjusted. That is, this embodiment provides an alternative solution for judging whether the air-conditioning system needs to be adjusted based on the comfort influence area and the overlap level of 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 cockpit, 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 cockpit. Therefore, the vehicle controller or the air-conditioning controller can determine the actual temperature and light intensity in each area of the vehicle by collecting the data of these sensors. Thus, when the actual temperature in a certain area is higher / lower than the preset temperature threshold, and / or when the light intensity in a certain area is higher / lower than the preset intensity threshold, the air-conditioning system can be adjusted. For example, when the actual temperature in the co-pilot area of the vehicle is collected by the temperature sensor installed in the co-pilot area of the vehicle and is lower than the preset temperature threshold, at this time, the user in the co-pilot area feels cold, then the air-conditioning system can be adjusted to blow warm air to raise the temperature in the co-pilot area, so that the user feels the temperature rising and improves the user's riding comfort.

[0061] During this process, the comfortable temperature range can also be introduced as the basis for adjusting the air conditioning system. During the driving of the vehicle, the temperature change in the cockpit is monitored in real time through the aforementioned temperature sensors to determine whether the current temperature is within the comfortable temperature range. If it is, the air conditioning system may not be adjusted. If not, the control parameters of the air conditioning system can be adjusted to change the temperature in the cockpit to the comfortable temperature range, so that the user can always obtain high comfort of the air conditioning during driving. It should be noted that although the temperature sensors are set in different areas of the vehicle cockpit, during the driving of the vehicle, especially when the air conditioning system is started, the temperature difference between different areas in the vehicle cockpit is generally not very large. Therefore, when judging whether the temperature is within the comfortable temperature range here, the temperature value used can be the temperature collected by the temperature sensor in a certain area, or the average value of all the temperatures collected by all the temperature sensors in the cockpit.

[0062] In this embodiment, the air conditioning system can also be controlled in zones. Specifically, when the temperature sensor collects that the temperature in a certain area is higher / lower than the preset temperature threshold, and / or the light sensor collects that the light intensity in a certain area is higher / lower than the preset intensity threshold, the air outlet speed, air volume, etc. of the independent air outlet corresponding to this area can be adjusted only. For example, if the light sensor detects that a certain area is directly irradiated by strong sunlight, the air outlet of the air conditioner corresponding to this area is adjusted to increase the cold air output. On the contrary, the cold air supply on the backlit side is appropriately reduced to avoid excessive cooling. By adjusting the air conditioning system in zones, not only the comfort of the passengers and drivers is improved, but also unnecessary energy consumption is reduced, and the overall efficiency of the air conditioning system is improved.

[0063] In an example, if the light sensor detects that the light intensity in a certain area is too high, the sunshade or other auxiliary devices can also be activated, which can further reduce the heat brought by direct sunlight and assist the user to obtain a high comfort experience.

[0064] When adjusting the air conditioning system in this embodiment, since the adjustment basis is based on the data collected by the light sensor and / or the temperature sensor, the data collected by these two sensors can also be used as the adjustment result to feedback the adjustment process, so that the final adjustment result of the air conditioning system can better meet the comfort requirements of users. Specifically, after the adjustment of the air conditioning system is completed, the adjusted temperature data can be collected by the temperature sensor, and whether the temperature in the current cockpit is within the comfortable temperature range can be judged by the change or trend of the temperature data. The comfortable temperature range can be the comfortable temperature change range preset by the user or the temperature range default by the system. Within this comfortable temperature range, users can feel higher comfort. Through the collected temperature value, the air conditioning system can be fine-tuned and optimized. Of course, users can also view the current air conditioning status or the current temperature value through the in-vehicle display screen, and even manually intervene in some settings to achieve more optimized adjustment of the air conditioning system.

[0065] Embodiment 3

[0066] On the basis of Embodiment 1 or Embodiment 2, this embodiment adjusts the auxiliary comfort system according to the control parameters of the adjusted air conditioning system. In this embodiment, the control parameters of the air conditioning system include the on / off state of the air conditioning system, on parameters such as air outlet speed, air volume, refrigeration / heating parameters, etc., and the off state of the air conditioning system; the auxiliary comfort system includes the steering wheel heating and / or ventilation function and the seat heating and / or ventilation function, which can be simply referred to as the steering wheel function and the seat function below.

[0067] After the adjustment of the air conditioning system is completed, monitor the comfort impact parameters in the cockpit. The comfort impact parameters here are preferably including temperature, and the temperature can be monitored by a temperature sensor. According to the change of the comfort impact parameters, adjust the control parameters of the auxiliary comfort system, that is, adjust the seat function and / or the steering wheel function, to realize the linkage between the air conditioner and the steering wheel and / or realize the linkage between the air conditioner and the seat, and finally make the auxiliary comfort system match the air conditioning system, so that users 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 will be 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 bad experience that the user feels the steering wheel or the seat is too cold. This process is significantly different from the traditional air conditioner and seat linkage strategy. In the traditional linkage strategy, when the temperature of the air conditioning system rises, the seat will turn on the ventilation function, and when the temperature of the air conditioning system drops, the seat will turn on the heating function. In this implementation, when it is detected that the temperature in the cockpit is low, the temperature of the air conditioning system is adjusted to increase the temperature in the cockpit, and at the same time, the heating function of the seat is started instead of the ventilation function, realizing a more intelligent linkage strategy and meeting the high comfort experience needs of users.

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

[0069] Regarding the linkage between the air conditioning system and the steering wheel heating / ventilation function, this embodiment solves the drawback in the prior art that there is a lack of an air conditioner and steering wheel linkage strategy. In the prior art, when the user feels that the steering wheel is cold, the user turns on the steering wheel heating function, and when the user feels that the steering wheel becomes hot, the user turns off the heating function and switches it repeatedly, resulting in a poor user experience. In this embodiment, according to the air conditioner and steering wheel linkage strategy, the control parameters of the steering wheel heating / ventilation function can be automatically adjusted, avoiding the user from manually adjusting frequently, and enabling more efficient and more user-friendly steering wheel temperature management.

[0070] The linkage control of the steering wheel heating / ventilation function and the air conditioning system in this embodiment aims to improve the comfort experience of the driver and passengers. Especially in cold weather conditions, through an intelligent linkage strategy, the steering wheel heating / ventilation function is integrated with the temperature in the cockpit to achieve more efficient and more user-friendly temperature management. The following is an implementation solution:

[0071] 1) Intelligent perception and prediction: The vehicle cockpit is equipped with multiple sensors, including a temperature sensor, a humidity sensor, and a human body infrared sensor, etc., which can monitor the temperature, humidity in the cockpit and whether the driver and passengers are present in real time.

[0072] 2) Personalized temperature setting: The driver and passengers can set their personal preferences through the center console screen or the mobile App, including the temperature of the steering wheel heating, the 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 preferences set by the driver and passengers to achieve a 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 activated. 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 cab 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 also be adjusted first, and then the steering wheel heating function can be intelligently activated according to the temperature change in the cockpit. In addition, this embodiment can also automatically adjust the heating intensity of the steering wheel according to the driver's physiological reactions, such as through heart rate monitoring, to ensure that the driver drives in a comfortable state.

[0074] 4) Energy-saving optimization: To improve energy efficiency, the system uses intelligent algorithms to intelligently adjust the start and stop times of the steering wheel heating and the air conditioning according to the driver's estimated driving time and the time to reach the destination, avoiding overheating or overcooling, thereby saving energy.

[0075] 5) Safety and health considerations: This embodiment also has a safety mechanism, such as overheat protection of the steering wheel, to prevent damage or a bad experience to the user caused by overheating of the steering wheel. At the same time, considering the health of the driver, the heating time of the steering wheel can also be automatically controlled to avoid adverse effects on the driver's skin caused by long-term high-temperature heating.

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

[0077] Regarding the linkage between the air conditioning system and the seat heating / ventilation function, this embodiment solves the problem of the existing air conditioning and seat linkage strategy (when the user raises the temperature, the seat starts the ventilation function, and when the user lowers the temperature, the seat starts the heating function), which has nothing to do with user comfort. For example, in the cold winter, after the user raises the air conditioning temperature, the seat will start the seat ventilation function, resulting in the body feeling cooler and the user's comfort experience decreasing, leading to a low usage rate of this linkage strategy. In this embodiment, however, the start-up requirements of the seat heating / ventilation function can be intelligently judged according to the temperature change in the cockpit, realizing the intelligent linkage of the air conditioning and the seat, and making the control parameters or parameters of the two match each other to enhance the user's comfort experience.

[0078] The air conditioner 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 real-time monitoring of the ambient temperature inside the vehicle / cockpit and the body temperature of the driver and passengers, so as to achieve the best thermal comfort. The following is a possible linkage strategy:

[0079] 1) Ambient temperature monitoring: The ambient temperature inside the vehicle is monitored in real time through temperature sensors set in different areas of the cockpit. The temperature outside the vehicle can also be obtained 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 technologies such as infrared sensors to more accurately adjust the temperature inside the vehicle.

[0081] 3) Intelligent judgment and linkage adjustment: When the temperature inside the vehicle is lower than the lower limit value of the preset comfortable temperature range, the seat heating function is activated. At the same time, the air conditioning system is adjusted to the warm air supply mode to quickly increase the temperature inside the vehicle; when the temperature inside the vehicle exceeds the upper limit value of the preset comfortable temperature range, the seat heating function is turned off or the seat ventilation function is activated, and the air conditioning is turned on to the cooling mode to reduce the temperature inside the vehicle. Of course, in this process, when the ambient temperature in the cockpit is lower than the lower limit value of the preset comfortable temperature range, the heating of the air conditioning system can be adjusted first, and then the seat heating function can be intelligently activated according to the temperature change in the cockpit; when the ambient temperature in the cockpit is higher than the upper limit value of the preset comfortable temperature range, the cooling of the air conditioning system can be adjusted first, and then the seat ventilation function can be intelligently activated according to the temperature change in the cockpit.

[0082] Furthermore, when the temperature inside the vehicle is at or near the comfortable temperature range, the seat heating / ventilation function or the air conditioning air outlet intensity can be finely adjusted according to the slight change in the body temperature of the driver and passengers to keep the temperature stable within the comfortable temperature range.

[0083] 4) Personalized settings: In this embodiment, through an easy-to-use control panel or terminal APP, the driver and passengers are allowed to set the aforementioned comfortable temperature range, seat heating / ventilation intensity, etc. according to their personal preferences, and save the personal preference configuration file set by the user. When the vehicle is started next time, the file settings will be automatically restored, improving the convenience of use and meeting the needs of different people at the same time.

[0084] 5) Energy-saving optimization: The linkage strategy of the air conditioner and the seat also includes an energy-saving mode, that is, after achieving the ideal thermal comfort, for example, when the temperature inside the vehicle is maintained within the preset comfortable temperature range, the air conditioning system or the seat system can be automatically adjusted to the lowest energy consumption state to avoid energy waste caused by excessive heating or cooling.

[0085] Through this seat and air conditioner linkage strategy based on thermal comfort, this embodiment can not only significantly improve the comfort experience of the driver and passengers, but also achieve the goal of energy conservation and emission reduction to a certain extent.

[0086] That is, in this embodiment, an intelligent linkage strategy between the air conditioner and the steering wheel is realized, and / or an intelligent linkage strategy between the air conditioner and the seat is realized, and the adjusted seat function and / or steering wheel function can be adapted to the control parameters of the air conditioning system to meet the actual needs of users at present, avoiding the problems of poor user experience caused by mechanical adjustment and low utilization rate of the linkage strategy in the traditional air conditioner and seat linkage scheme, and realizing intelligent linkage adjustment, significantly improving the comfort experience of users.

[0087] Moreover, during the linkage process of the air conditioning system and the auxiliary comfort system in this embodiment, a communication module can also be provided to enable real-time interaction of information or data between the two, realizing synchronous operation of the two, so as to ensure the stable execution of the linkage strategy of the air conditioning system and the auxiliary comfort system. In addition, this embodiment can also provide an easy-to-use control panel on the in-vehicle device or a simple APP on the terminal device, allowing users to easily set and adjust the linkage parameters of the steering wheel or seat and the air conditioner to meet various user scenarios.

[0088] Embodiment 4

[0089] In this embodiment, the adjustment process of the auxiliary comfort system based on relative position information and influence attributes is mainly described. This process can be independent of the adjustment process of the air conditioning system and is applicable to scenarios where the air conditioning system does not need to be adjusted or the air conditioning system is not linked with the auxiliary comfort system.

[0090] Specifically, after obtaining the relative position information between the vehicle and the comfort-affecting object, based on the relative position information or the change of the relative position information, such as the relative position between the vehicle and the sun, combined with the vehicle's orientation information, determine the comfort-affecting area generated by the comfort-affecting object in the vehicle cockpit. The process can refer to the relevant description in Embodiment 1 and will not be elaborated here in this embodiment. After that, determine whether the comfort-affecting area includes the steering wheel area or the seat area. For example, determine whether the sunlight shines on the steering wheel or the seat. This process can be realized by the monitoring device in the cockpit. Identify the content included in the comfort-affecting area through the video stream data or image data collected by the monitoring device. When the comfort-affecting area includes the steering wheel area and / or the seat area, adjust the control parameters of the steering wheel ventilation / heating function and / or adjust the control parameters of the seat ventilation / heating function. In one example, the above-mentioned comfort-affecting area including the steering wheel area or the seat area can also be realized through the concept of overlap. That is, calculate the overlap between the comfort-affecting area and each seat area where there are occupants. When the overlap is higher than the first threshold, it is considered that the comfort-affecting area includes the seat area, and calculate the overlap between the comfort-affecting area and the steering wheel. When the overlap is higher than the fifth threshold, it is considered that the comfort-affecting area includes 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 is the ratio of the area where the sunlight shines on the steering wheel to the entire circular steering wheel area.

[0091] For example, taking the comfort-affecting object as the sun, based on the relative position between the sun and the vehicle, combined with the vehicle's orientation information, determine the irradiation area of the sunlight in the vehicle cockpit. Determine whether the irradiation area includes the steering wheel. If it does, activate the steering wheel ventilation function to prevent the driver's hands from sweating under the sunlight, which may pose a safety hazard to driving. At the same time, the steering wheel ventilation function can also cool the steering wheel area, enabling the user to drive with high comfort.

[0092] For another example, taking the comfort-affecting object as the buildings on both sides of the road, the shadow generated by the buildings can completely or partially cover the vehicle cockpit area. Through the position information of the buildings on the current driving map of the vehicle, determine the relative position between the buildings and the sun, and thus obtain the shadow area generated by the buildings. Then, based on the vehicle's position information and orientation information, determine the comfort-affecting area of the shadow area on the vehicle cockpit. If the comfort-affecting area includes the vehicle seat area, assuming it is in the cold winter, at this time, the shadow generated by the buildings acting on the vehicle seat area can reduce the temperature of the seat area. At this time, the heating function of the seat can be activated to increase the temperature of the seat area, thereby enhancing the user's driving and riding comfort experience.

[0093] Of course, in this embodiment, it is also possible to determine whether it is necessary to adjust the steering wheel function and / or the seat function based on the data collected by the temperature sensors and / or light sensors installed in different areas of the cockpit. For example, taking the comfort-affecting object as the sun and the vehicle driving scenario as a hot summer, when the light sensor installed in the steering wheel area or the seat area detects a high light intensity in the steering wheel area or the seat area, the ventilation function of the steering wheel or the ventilation function of the seat can be activated to avoid a high temperature in the steering wheel area or the seat area due to sunlight irradiation, which may cause discomfort to the user. By activating the ventilation function, the temperature in the steering wheel area or the seat area can be decreased, enabling the user to feel a cool state and enhancing the user's driving and riding comfort experience.

[0094] In a possible implementation manner of the present application, the regional ambient temperature of the seat area can also be detected by the aforementioned temperature sensor, and the overall ambient temperature is determined based on the average temperature detected by all the temperature sensors in the vehicle. Then, it is determined whether the regional ambient temperature or the overall ambient temperature is within a preset comfortable temperature range. If not, the control parameters of the auxiliary comfort system are adjusted according to the comfort preferences and influencing attributes of the user for the auxiliary comfort system. In this implementation manner, on the one hand, it is determined whether adjustment is needed based on the ambient temperature, and on the other hand, the comfort preferences of the user are emphasized. Here, the comfort preferences refer to the steering wheel / seat, and can be obtained from the historical operations or set data of the user for the steering wheel / seat. That is, when adjusting the control parameters of the auxiliary comfort system, the preference data of the user is considered, so that the adjusted steering wheel / seat can better meet the comfort requirements of the user. In addition, the aforementioned comfortable temperature range refers to the comfortable temperature range of the ambient temperature in the vehicle cockpit, and this range can be obtained from the personal preference data set by the user on the vehicle center control screen or the mobile APP, such as setting the ambient temperature in the cockpit, etc., to meet the personalized setting needs of the user. Thus, when adjusting the auxiliary comfort system or the air conditioning system, the personal preference data set by the user can be referred to, and the temperature in the cockpit can be adjusted to the comfortable temperature range set by the user, enabling the user to obtain 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, when obtaining the temperature range in the vehicle cockpit when the user last drove the vehicle, this temperature range is used as the comfortable temperature range. This situation is preferably applicable to the case where the user has not set personal preference data. That is, when the user has not set a comfortable temperature range, the temperature range in the cockpit 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 made to be within this comfortable temperature range, so that the user can obtain a high comfort experience. At the same time, this 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 this temperature range, it is necessary to adjust the control parameters of the air conditioning system and / or the auxiliary comfort system.

[0095] Therefore, in this embodiment, the adjustment of the seat function and / or the steering wheel function is realized based on 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 this embodiment, avoiding manual adjustment by the user. Moreover, the user's comfort preference is considered during the adjustment process, so that the adjusted seat function and / or steering wheel function can meet the user's needs and improve the user's comfort experience.

[0096] Embodiment 5

[0097] Regardless of whether the control parameters of the air conditioning system and / or the auxiliary comfort system are adjusted through any one of the above embodiments or a combination of several embodiments, when the ambient temperature in the vehicle cockpit is within the aforementioned preset comfortable temperature range, in order to save energy consumption, it is preferably to adjust the power consumption of the air conditioning system and the auxiliary comfort system to the lowest level. However, the prerequisite for adjusting to the lowest level is that the temperature in the cockpit cannot be lower than the comfortable temperature range to avoid affecting the user's comfort experience.

[0098] In a possible implementation manner of this embodiment, after the adjustment is completed, that is, after the ambient temperature in the cockpit is within the comfortable temperature range, the body temperature of the driver can also be detected by an infrared sensor installed in the vehicle. Note that here it is preferably to only focus on the change in the driver's body temperature. When the driver's body temperature changes, according to the change trend, the control parameters of the air conditioning system and / or the auxiliary comfort system are fine-tuned to enable the driver to obtain a higher comfort experience on the premise that all the people in the cockpit 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 driver's body temperature has dropped by 0.5 - 1 °C. At this time, the control parameters of the auxiliary comfort system can be fine-tuned, such as raising the temperature of the seat heating by 1 - 2 °C, so that the driver can obtain a better experience. However, at this time, the ambient temperature in the vehicle cockpit is still within the preset comfortable temperature range, and other people in the cockpit can also feel a high level of comfort.

[0099] In a possible implementation manner of this application, before executing the above embodiments, a pre-judgment step can be added to make the process of adjusting the control parameters of the air conditioning system and / or the auxiliary comfort system meaningful or necessary. Specifically, before the adjustment, the remaining time to reach the destination of this trip can be predicted according to the current driving route of the vehicle. This remaining time to reach the destination can also be directly obtained from the vehicle's navigation information. If the remaining time to reach the destination is too short, there is no need to adjust the air conditioning system and / or the auxiliary comfort system. If it still takes a relatively 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 influencing attributes.

[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 aforementioned destination. For example, when the vehicle is about to reach the destination, the air conditioning system or the auxiliary comfort system can be turned off in advance to achieve the energy-saving effect.

[0101] The above is the method embodiment proposed by this application. Based on the same inventive concept, this application also provides a linkage control device for a vehicle, and its structure is as Figure 2 shown.
