Description

Technical Field

[0001] This invention relates to the field of vehicle thermal management technology, specifically to an air conditioning control method, system, and vehicle. Background Technology

[0002] As the core device for regulating the temperature of the driving environment, the vehicle's air conditioning system has a unique energy supply method in new energy vehicles. The power battery of a new energy vehicle not only needs to power the drive motor but also continuously power the air conditioning system and other onboard electrical appliances. Especially in extreme temperature environments, the energy consumption of the air conditioning system increases significantly, directly leading to a noticeable reduction in the vehicle's driving range. Therefore, optimizing the energy efficiency of the air conditioning system is crucial for reducing battery power consumption and increasing vehicle range. To ensure thermal comfort and achieve rapid cooling / heating while maintaining temperature stability, the air conditioning system typically needs to operate at higher power, which leads to a significant increase in energy consumption. Conversely, limiting the operating power of the air conditioning system to reduce energy consumption will prolong the temperature adjustment time and may affect temperature stability, thereby reducing thermal comfort. Therefore, how to minimize energy consumption while meeting basic thermal comfort requirements, and achieve a good balance between thermal comfort and energy consumption, is a critical technical problem that needs to be solved in air conditioning system control. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of this application is to provide an air conditioning control method, system and vehicle that aims to achieve a better balance between thermal comfort and energy consumption under the current passenger position information and energy management mode.

[0004] In a first aspect, embodiments of this application provide an air conditioning control method, including:

[0005] Obtain the seating position information of the occupants inside the vehicle;

[0006] Obtain air conditioning operating information; the air conditioning operating information includes ambient temperature, air conditioning set target temperature, total air volume of air conditioning, and air guide vane opening information of each air outlet;

[0007] Based on the passenger location information and the air conditioning operating condition information, the thermal comfort value and the air conditioning system energy consumption value are determined.

[0008] Based on the thermal comfort value and the energy consumption value of the air conditioning system, determine the synergistic optimization value of thermal comfort and energy consumption under the current energy management mode;

[0009] Based on the aforementioned optimized values ​​for thermal comfort and energy consumption, instructions are generated to control the real-time operating power of the air conditioning system.

[0010] In this way, the thermal comfort value and the air conditioning system energy consumption value are determined according to the sitting position information of different passengers in the vehicle and the air conditioning working condition information, and the weight of the thermal comfort value and the air conditioning system energy consumption value is reasonably distributed in combination with the current energy management mode, so that the instruction for controlling the real-time working power of the air conditioning system is generated, and the thermal comfort and energy consumption can be matched with the current sitting position information and energy management mode, and a good balance between the thermal comfort and energy consumption under the current sitting position information and energy management mode is achieved.

[0011] In a possible embodiment, the air conditioning control method further includes:

[0012] determining the guide vane opening degree information of each air outlet based on the sitting position information;

[0013] generating an instruction for controlling the opening degree of each air outlet of the air conditioning system based on the guide vane opening degree information of each air outlet.

[0014] In this way, the guide vane opening degree information of each air outlet is obtained according to the preset mapping relationship table of the sitting position information-guide vane opening degree information of each air outlet, the instruction for controlling the opening degree of each air outlet of the air conditioning system is generated, the instruction is sent to the motor of each air outlet of the air conditioning system, the motor is driven to change the angle of the guide vane of the guide plate at each air outlet, and the opening degree of each air outlet of the air conditioning system is controlled. Specifically, the opening degree of the air outlet on the side where a passenger is sitting is increased, and the opening degree of the air outlet on the side where no passenger is sitting is reduced, so that more air flow is concentrated on the position where a passenger is sitting, the thermal comfort of the passenger is improved, and a small amount of air flow is provided for the position where no passenger is sitting, so that the situation that the temperature field is seriously uneven due to a large temperature difference between different regions is avoided, and the temperature in the vehicle is kept stable.

[0015] In a possible embodiment, the determination of the thermal comfort value and the air conditioning system energy consumption value based on the sitting position information and the air conditioning working condition information includes:

[0016] determining the real-time air flow of each air outlet based on the total air flow of the air conditioning system and the guide vane opening degree information of each air outlet;

[0017] determining the temperature weight coefficient of the thermal comfort value calculation formula and the air flow weight coefficient corresponding to each air outlet based on the sitting position information, determining the air conditioning target temperature preset optimal value corresponding to the sitting position information and the air flow preset optimal value of each air outlet;

[0018] determine the thermal comfort value based on the air conditioner set target temperature, the air conditioner target temperature preset optimal value, the temperature weight coefficient, the real-time air outlet volume of each air outlet, the air outlet volume preset optimal value of each air outlet, and the air outlet volume weight coefficient corresponding to each air outlet;

[0019] determine the air conditioner system energy consumption value based on the air conditioner set target temperature, the environment temperature, the total air outlet volume of the air conditioner, and the working time length.

[0020] In this way, the thermal comfort value is calculated by comparing the air conditioner set target temperature and the pre-labeled air conditioner target temperature preset optimal value, comparing the real-time air outlet volume of each air outlet and the pre-labeled air outlet volume preset optimal value of each air outlet, and assigning weights to the temperature and the air outlet volume, so as to realize the quantification of the thermal comfort value. The air conditioner system energy consumption value is associated with the air conditioner set target temperature, the environment temperature, the total air outlet volume of the air conditioner, and the working time length, covers the core energy consumption influencing factors of the air conditioner system, and realizes the objective and accurate evaluation of the energy consumption value. Therefore, through the quantification of the thermal comfort value and the objective and accurate evaluation of the energy consumption value, the decision accuracy and reliability of the control method can be improved.

[0021] In a possible embodiment, when determining the thermal comfort value, the following steps are included:

[0022] obtain a temperature difference value by subtracting the air conditioner target temperature preset optimal value from the air conditioner set target temperature;

[0023] obtain a temperature-related contribution term by weighting the square of the temperature difference value by the temperature weight coefficient;

[0024] obtain an air outlet volume difference value of each air outlet by subtracting the corresponding air outlet volume preset optimal value from the real-time air outlet volume of each air outlet;

[0025] obtain an air volume-related contribution term corresponding to each air outlet by weighting the square of the air outlet volume difference value of each air outlet by the air outlet volume weight coefficient corresponding to each air outlet;

[0026] obtain the thermal comfort value by summing the temperature-related contribution term and the air volume-related contribution term corresponding to each air outlet.

[0027] In this way, by summing the squares of the difference values and the differentiated weights, the thermal comfort value calculated is closer to the actual experience of the occupant, and the comfort feeling misjudgment caused by the same weight of each air outlet is avoided.

[0028] In a possible embodiment, when determining the air conditioner system energy consumption value, the following steps are included:

[0029] obtain a temperature difference parameter by subtracting the air conditioner set target temperature from the environment temperature;

[0030] weighting the temperature difference parameter by a pre-calibrated temperature difference correction coefficient to obtain a power contribution item corresponding to the compressor;

[0031] weighting the total air volume of the air conditioner by a pre-calibrated air volume correction coefficient to obtain a power contribution item corresponding to the air blower;

[0032] summing the power contribution item corresponding to the compressor and the power contribution item corresponding to the air blower to obtain a real-time total power of the air conditioning system;

[0033] time-integrating the real-time total power to obtain an air conditioning system energy consumption value of the air conditioning system within a working time length.

[0034] In this way, the energy consumptions of the compressor and the air blower are respectively evaluated, and the calculation of the energy consumption value is adapted to different vehicle models through pre-calibration, so that the calculation result is objective and accurate.

[0035] In a possible embodiment, the determining of the thermal comfort and energy consumption collaborative optimization value in the current energy management mode based on the thermal comfort value and the air conditioning system energy consumption value comprises:

[0036] determining a thermal comfort value weight and an air conditioning system energy consumption weight based on the energy management mode;

[0037] calculating a thermal comfort and energy consumption collaborative optimization value based on the thermal comfort value, the thermal comfort value weight, the air conditioning system energy consumption value, and the air conditioning system energy consumption weight.

[0038] In this way, the energy management mode of the vehicle or the air conditioner is set by the user or automatically set by the vehicle, so as to meet different use requirements of the user, and the double-target collaborative priority of the thermal comfort and the energy consumption of the air conditioning system can be matched in different energy management modes, so as to avoid the ambiguity of the double-target decision. Specifically, when the energy management mode of the vehicle or the air conditioner is the power saving mode focusing on economy, the mode is suitable for a scenario of pursuing the maximum cruising range, is not sensitive to the thermal comfort, and is sensitive to the energy consumption, so that the thermal comfort value weight is much smaller than the air conditioning system energy consumption weight. When the energy management mode of the vehicle or the air conditioner is the comfort mode focusing on comfort, the mode is suitable for a scenario of pursuing the driving experience, is not sensitive to the energy consumption, and is sensitive to the thermal comfort, so that the thermal comfort value weight is much larger than the air conditioning system energy consumption weight. When the energy management mode of the vehicle or the air conditioner is the balanced mode, the mode is suitable for a scenario of pursuing the driving comfort and low energy consumption, and the sensitivity degrees of the energy consumption and the thermal comfort are close to each other, so that the thermal comfort value weight is close to the air conditioning system energy consumption weight.

[0039] In a possible embodiment, the generating, based on the opening information of the guide vanes of the air outlets, of an instruction for controlling the opening of the air outlets of the air conditioning system comprises:

[0040] Based on the thermal comfort and energy consumption collaborative optimization value, a target working power of the air conditioning compressor and a target working power of the air blower are determined through a preset mapping table;

[0041] Based on the target working power of the air conditioning compressor and the target working power of the air blower, an instruction for controlling the real-time working power of the air conditioning system is generated, wherein the real-time working power of the air conditioning system comprises a real-time working power of the air conditioning compressor and a real-time working power of the air blower.

[0042] In this way, the target power of the compressor and the air blower is directly queried through the preset mapping table, real-time complex calculation is avoided, control delay is reduced, the change of the collaborative optimization value is ensured to be quickly responded to by power adjustment, a closed loop of "energy consumption calculation, optimization decision, power control, and energy consumption recalculation" is formed, and continuous optimization is realized in a preset time period.

[0043] In a possible embodiment, the obtaining of the sitting position information of the passenger in the vehicle comprises:

[0044] Obtaining the safety belt state information of each seat;

[0045] Obtaining image information captured by an in-vehicle camera;

[0046] Based on the safety belt state information and the image information, the sitting position information of the passenger in the vehicle is determined.

[0047] In this way, the safety belt state information of each seat and the image information captured by the in-vehicle camera are used as two dimensions of judgment basis to determine the sitting position information of the passenger in the vehicle, so that the accuracy of the sitting position information is ensured.

[0048] In a second aspect, an air conditioning control system is provided, which is configured to implement the air conditioning control method.

[0049] In a third aspect, a vehicle is provided, which comprises the air conditioning control system.

[0050] The beneficial effects of the present application are: the present application determines the thermal comfort value and the air conditioning system energy consumption value by the seat position information of different vehicle occupants and the air conditioning working condition information, and reasonably distributes the weights of the thermal comfort value and the air conditioning system energy consumption value based on the current energy management mode, so as to generate instructions for controlling the real-time working power of the air conditioning system, so that the thermal comfort and energy consumption can match the current seat position information and energy management mode, and a good balance between thermal comfort and energy consumption under the current seat position information and energy management mode is achieved.

Please refer to Figure 3 , Figure 3 The schematic diagram of the thermal management controller disclosed in the embodiments of the present application. The thermal management controller comprises an information receiving unit, an information processing unit and a control unit.

[0068] 1. Based on the seating position information of the vehicle occupants sent by the cabin controller and the body controller received by the information receiving unit, comprehensive judgment is performed to obtain the seating position information of the vehicle occupants. For example, if the cabin controller determines that the vehicle occupants are the front row driver, the front row passenger and the second row passenger based on the image information, and the body controller determines that the vehicle occupants are the front row driver and the second row passenger based on the fastening state, it is possible that the front row passenger does not fasten the seat belt, and the thermal management controller determines that the vehicle occupants are the front row driver, the front row passenger and the second row passenger. If the cabin controller determines that the vehicle occupants are the front row driver, the front row passenger and the second row passenger based on the image information, and the body controller determines that the vehicle occupants are the front row driver and the second row passenger based on the fastening state, it is possible that the camera does not capture the second row passenger, and the thermal management controller determines that the vehicle occupants are the front row driver, the front row passenger and the second row passenger.

Specifically: Based on the total air volume of the air conditioner and the opening information of the guide vanes of each air outlet, determine the real-time air volume of each air outlet; based on passenger location information, determine the temperature weighting coefficient of the thermal comfort value calculation formula and the air volume weighting coefficient corresponding to each air outlet, determine the preset optimal value of the air conditioning target temperature and the preset optimal value of the air volume of each air outlet corresponding to the passenger location information; based on the air conditioning set target temperature, the preset optimal value of the air conditioning target temperature, the temperature weighting coefficient, the real-time air volume of each air outlet, the preset optimal value of the air volume of each air outlet, and the air volume weighting coefficient corresponding to each air outlet, determine the thermal comfort value; based on the air conditioning set target temperature, ambient temperature, total air volume of the air conditioner, and operating time, determine the air conditioning system energy consumption value.

[0071] 4.

Specifically: based on the energy management mode, determine the weights of thermal comfort values ​​and air conditioning system energy consumption; based on thermal comfort values, thermal comfort weights, air conditioning system energy consumption values, and air conditioning system energy consumption weights, calculate the synergistic optimization value of thermal comfort and energy consumption.

[0072] The control unit is configured to: generate instructions to control the real-time operating power of the air conditioning system based on the synergistic optimization values ​​of thermal comfort and energy consumption, and send the control instructions to the compressor and blower.

[0073] Please see Figure 4 , Figure 4 This is a schematic flowchart of the air conditioning control method disclosed in an embodiment of this application. The air conditioning control method includes the following steps:

[0074] S1. Obtain the seating position information of the passengers inside the vehicle.

[0075] Specifically, the process involves: acquiring seatbelt status information for each seat; acquiring image information captured by in-vehicle cameras; and determining the seating positions of occupants based on the seatbelt status information and the image information.

[0076] The information receiving unit receives the seat position information of the vehicle occupant sent by the cabin controller and the vehicle body controller. Based on the seat position information of the vehicle occupant sent by the cabin controller and the vehicle body controller received by the information receiving unit, the information processing unit comprehensively judges to obtain the seat position information of the vehicle occupant. For example, if the cabin controller determines that the vehicle occupant is a front-row driver, a front-row passenger, and a second-row empty person based on the image information, and the vehicle body controller determines that the vehicle occupant is a front-row driver, a front-row empty passenger, and a second-row empty person based on the fastening state, it is possible that the front-row passenger does not fasten the safety belt, and the thermal management controller determines that the vehicle occupant is a front-row driver, a front-row passenger, and a second-row empty person. If the cabin controller determines that the vehicle occupant is a front-row driver, a front-row passenger, and a second-row empty person based on the image information, and the vehicle body controller determines that the vehicle occupant is a front-row driver, a front-row passenger, and a second-row person based on the fastening state, it is possible that the camera does not capture the second-row passenger, and the thermal management controller determines that the vehicle occupant is a front-row driver, a front-row passenger, and a second-row person.

[0077] S2, based on the seat position information, determine the guide vane opening degree information of each air outlet; based on the guide vane opening degree information of each air outlet, generate a control instruction for controlling the opening degree of each air outlet of the air conditioning system.

[0078] Specifically, the information processing unit determines the guide vane opening degree information of each air outlet based on the seat position information obtained in S1; based on the guide vane opening degree information of each air outlet, generates a control instruction for controlling the opening degree of each air outlet of the air conditioning system, and sends the control instruction to the motor of each air outlet of the air conditioning system through the control unit. The motor works to change the angle of the guide vane of the air outlet, thereby controlling the opening degree of each air outlet of the air conditioning system. After the motor completes the adjustment, the guide vane opening degree information of each air outlet can be fed back to the thermal management controller.

[0079] When obtaining the seat position information and determining the guide vane opening degree information of each air outlet, taking a vehicle with two rows of seats as an example, the guide vane opening degree information of each air outlet can be obtained according to the preset mapping relationship table of the seat position information-the guide vane opening degree information of each air outlet in Table 1 below. In the table, " is used to indicate that there is a person, " is used to indicate that there is no person, and the "first opening degree", "second opening degree", "third opening degree", "fourth opening degree", and "fifth opening degree" of each air outlet are increasing in opening degree. For example, the "first opening degree" is that the air outlet is closed, the "second opening degree" is that the air outlet is opened by 20%, the "third opening degree" is that the air outlet is opened by 50%, the "fourth opening degree" is that the air outlet is opened by 80%, and the "fifth opening degree" is that the air outlet is completely opened.

[0080] The air outlet on the side where people are present is increased in opening degree, and the air outlet on the side where people are not present is reduced in opening degree, so that more air volume is concentrated on the position where people are present, which can improve the passenger thermal comfort, and also provides a small amount of air volume for the position where people are not present, avoids the case that the temperature field is seriously uneven due to too large temperature difference in different areas, and is beneficial to keep the temperature in the vehicle stable.

[0086] This step includes:

[0088] The information receiving unit receives the working state of the compressor, the information processing unit determines the air conditioner total air volume according to the working state of the compressor and the configuration parameters of the compressor, and the air deflector blade opening degree information of each air outlet, so as to know the air outlet distribution ratio of each air outlet, and according to the air conditioner total air volume and the air outlet distribution ratio of each air outlet, the real-time air volume of each air outlet can be obtained. Taking a vehicle with two rows of seats as an example, the air conditioner total air volume is , the air volume of the front row driver side air outlet is , the air volume of the front row co-driver side air outlet is , and the air volume of the second row seat air outlet is , , , , , The collection / measurement / setting unit of each of the above is L / min.

[0090] Based on the seating position information, the temperature weight coefficient of the thermal comfort value calculation formula and the air outlet weight coefficient corresponding to each air outlet are determined. Taking a vehicle with two rows of seats as an example, the temperature weight coefficient can be 0.55, the air outlet correction coefficient of the front row driver side air outlet, the front row co-driver side air outlet and the second row seat air outlet are 0.2, 0.2 and 0.15 respectively, and the sum of the three is 0.45. The mapping relationship table of preset seating position information-air outlet weight coefficient of each air outlet in Table 2 is obtained, and the guide vane opening degree information of each air outlet is obtained. In the table, “ ” means that there is someone, ” means that there is no one.
