Exceptions to this definition occur only when combinations of elements, functions, steps, or operations are mutually internally exclusive in a specific way.

[0030] In conventional fuel-powered vehicles, when there is a need for heating in the passenger compartment, the waste heat generated by the engine and the waste heat from the burned gas can be used to heat the air through heat transfer. This heat transfer process is achieved by a thermal coolant. After the coolant has absorbed the heat from the waste heat, it flows through the heater core in the heating ventilation and air conditioning (HVAC) system, transferring the heat to the air. The heated air then reaches the passenger compartment through the air outlet, satisfying the heating needs of the passenger compartment. In conventional fuel-powered vehicles, there is always a sufficient source of waste heat, so the temperature of the air after passing through the heater core is usually high enough. The in-vehicle terminal can measure the temperature of the air heated by the heater core by placing a temperature sensor behind the heater core. Temperature After that, the in-vehicle terminal controls the opening value of the hybrid damper to mix unheated air with the heated air so that the air can reach the target temperature when it is blown out from the air outlet.

[0031] In electric vehicles, the waste heat generated by the vehicle is much less than that of fuel-powered vehicles. In recent years, as the electric vehicle industry grows, more and more heat pump systems are being applied. When there is a heating need in the passenger compartment, the vehicle uses a heat pump or heater. , e.g., a positive temperature coefficient thermistorThe air is heated to the heating temperature using a Positive Temperature Coefficient (PTC). The in-vehicle terminal then controls the hybrid damper so that the outlet temperature reaches the target temperature. The calculation method for the heating temperature of the air conditioning heater core is that, if the hybrid damper is at 100% full heating position, the heating temperature is equal to the sum of the target temperature and the temperature compensation amount.

[0032] The temperature compensation amount is determined by factors such as the ambient temperature and the air volume. When the ambient temperature and the air volume differ, the heat loss from the heater core to the air outlet differs. Therefore, the temperature compensation amount calculated based on the heat loss also differs. Generally, in order to ensure that the temperature at the air outlet meets the heating needs, the in-vehicle terminal intentionally increases the temperature compensation amount so that the heating needs of the passenger compartment are met.

[0033] This application proposes a viable solution to eliminate the temperature sensor behind the heater core to save costs. Furthermore, because the hybrid damper is located behind the heater core, if a temperature sensor were located on the surface of the heater core, the temperature sensor would inevitably affect the operation of the hybrid damper, creating a safety hazard. At the same time, to meet the high demands on power consumption in electric vehicles, more accurate heating demand control methods are needed.

[0034] To address the above-mentioned problem, the present application proposes a method for controlling a heat pump system in a multi-temperature zone air conditioning box. In this application, when only cooling is needed in the passenger compartment, the vehicle terminal can fix the hybrid damper to the full cooling position to meet the vehicle's cooling needs. In this application, when heating is needed in the passenger compartment and the passenger compartment is heated using PTC, the vehicle terminal can fix the hybrid damper to the full heating position and control the PTC to achieve a target temperature for the discharge air temperature. Furthermore, in this application, when heating is needed in the passenger compartment and the residual heat of the motor and / or battery is used for heating, the vehicle terminal can adjust the opening value of the hybrid damper to ensure that the discharge air temperature reaches the target temperature. Furthermore, in this application, when heating is needed in the passenger compartment and the passenger compartment is heated using a compressor, the vehicle terminal can control the hybrid damper according to the compressor rotation speed. In this application, when the compressor rotation speed is above 850 rpm, which is not the minimum operable rotation speed, the vehicle terminal can fix the hybrid damper to the full heating position. This allows the vehicle terminal to control the compressor rotation speed so that the discharge temperature reaches the target discharge temperature. When the compressor rotation speed is maintained at or above the minimum operable rotation speed T seconds and the difference between the discharge temperature and the target temperature is greater than a first threshold, the vehicle terminal can fix the compressor rotation speed at the minimum operable rotation speed. T is an empirical value, and the minimum operable rotation speed of the compressor can be set to 850 rpm. At the same time, the vehicle terminal can also adjust the opening of the hybrid damper so that the discharge temperature reaches the target discharge temperature. This application not only eliminates the temperature sensor behind the heater core, thereby reducing costs, but also enables the vehicle terminal to precisely control the heating needs of the passenger compartment, thereby achieving the goal of energy conservation.

[0035] The technical solutions of the present application will be described in detail below using specific examples. Some of the following specific examples can be combined with each other, and the same or similar concepts or processes may not be repeatedly described in some examples.

[0036] FIG. 1 shows a structural schematic diagram of a heat pump system provided according to one embodiment of the present application. 1 As shown in the figure, the dotted lines indicate the air flow path. When the blown air passes through the heater core, the air is heated. The heated air reaches the passenger compartment via the air conditioning outlet, providing heating for the passenger compartment. As the air passes through the air conditioning outlet, a temperature sensor located at the air conditioning outlet acquires the outlet temperature. The temperature sensor uploads the measured outlet temperature to the vehicle terminal. After acquiring the measured temperature from the temperature sensor, the vehicle terminal controls the hybrid damper according to the outlet temperature and the target temperature. The vehicle terminal adjusts the opening value of the hybrid damper to adjust the amount of unheated air waiting to be mixed in and thereby adjust the outlet temperature.

[0037] In this application, the in-vehicle terminal is used as an execution entity to execute the heat pump system control method for a multi-temperature zone air-conditioning box according to the following embodiment. Specifically, the execution entity may be a hardware device of the in-vehicle terminal, or a software application in the in-vehicle terminal that implements the following embodiment, or a computer-readable storage medium on which the software application that implements the following embodiment is installed, or the code of the software application that implements the following embodiment.

[0038] 2 shows a flowchart of a heat pump system control method for a multi-temperature zone air conditioning box according to one embodiment of the present application. Based on the embodiment shown in FIG. 1, as shown in FIG. 2, the method according to this embodiment can include steps S101 to S102, with the in-vehicle terminal as the execution body.

[0039] In S101, the vehicle temperature adjustment control mode, target temperature, temperature adjustment demand and blown-out temperature for each temperature zone of the vehicle are acquired, and the blown-out temperature is measured by a temperature sensor at the blown-out port corresponding to the temperature zone.

[0040] In this embodiment, the on-board terminal can acquire the vehicle's temperature adjustment control mode. The temperature adjustment control mode can include one or more of the following modes: cooling by a compressor, heating by a heater, heating by a motor and / or battery residual heat, and heating by a compressor. When the temperature adjustment control mode is heating by a compressor, different methods for calculating the hybrid damper opening value can be used for situations where the compressor rotation speed is higher than the minimum operable rotation speed and situations where the compressor rotation speed is equal to or lower than the minimum operable rotation speed.

[0041] The vehicle terminal can also acquire a target temperature, which is the air conditioning temperature set by the user on the vehicle terminal. In this embodiment, the temperature adjustment is used to adjust the outlet temperature so that the outlet temperature reaches the target temperature, thereby causing the passenger compartment temperature to reach the target temperature.

[0042] The vehicle terminal can also acquire a temperature adjustment demand for each temperature region. Each temperature region includes at least one air outlet. For example, the driver's seat in the passenger compartment can be a temperature region that may include two air outlets on both the left and right sides of the steering wheel. Furthermore, for example, the rear seats in the passenger compartment can be a temperature region that includes one air outlet. The temperature adjustment demand for different temperature regions can be determined according to the air outlet volume of the air outlets in the different temperature regions. For example, if both air outlets in the temperature region corresponding to the driver's seat are open, the corresponding temperature adjustment demand can be 2. If only one of the two air outlets in the temperature region corresponding to the driver's seat is open, the corresponding temperature adjustment demand can be 1. If one of the two air outlets in the temperature region corresponding to the driver's seat is closed and the other is half-open, the temperature adjustment demand can be 0.5. Furthermore, for example, if the size of the air outlet for the rear seat is 1.5 times the size of the air outlet for the driver's seat, when the air outlet for the rear seat is open, the temperature adjustment demand for the temperature region is 1.5.

[0043] The vehicle terminal can also acquire the outlet temperature of each outlet using a temperature sensor disposed at each outlet.

[0044] In S102, the opening value of the hybrid damper for each temperature region is adjusted according to the temperature adjustment control mode, the target temperature, and the temperature adjustment demand and blowing temperature for each temperature region so that the blowing temperature for each temperature region reaches the target temperature.

[0045] In this embodiment, the vehicle terminal can calculate the opening value of the hybrid damper based on the temperature adjustment control mode, the target temperature, and the temperature adjustment demand and blowout temperature of each temperature region acquired in S101. The vehicle terminal can adjust the amount of untreated air that can be mixed into each hybrid damper by controlling the opening of the hybrid damper. The vehicle terminal can adjust the amount of untreated air that can be mixed into the cold air / hot air. air By adding this, it is possible to adjust the temperature of the air blown out from the air outlet.

[0046] In one example, when one hybrid damper in the vehicle corresponds to multiple air outlets, the outlet temperatures of the multiple air outlets corresponding to the hybrid damper are determined according to the amount of unprocessed air entering from the hybrid damper. In this case, the vehicle terminal acquires the temperatures of the multiple air outlets corresponding to the hybrid damper, and then collectively calculates the temperature difference of the multiple air outlets to obtain the opening degree of the hybrid damper. Specific steps include steps 1 to 4.

[0047] In step 1, the weight of each of the plurality of air outlets is determined according to the distance from each of the air outlets to the heater core.

[0048] In step 2, the temperature difference between the outlet temperature of each outlet and the target temperature is calculated based on the outlet temperature of each outlet.

[0049] In step 3, the final target temperature difference is calculated based on the weight and temperature difference of each air outlet.

[0050] In step 4, the opening value of the hybrid damper is determined according to the product of the target temperature difference and a preset parameter.

[0051] In another example, each air outlet in each temperature zone of the vehicle may correspond to one hybrid damper. The hybrid damper can mix untreated air with the air blown out from the air outlet so that the outlet temperature of the air outlet reaches a target temperature. In this case, the vehicle terminal can calculate the opening degree value of the hybrid damper for the air outlet based on the outlet temperature of each air outlet. Specific steps can include steps 1 to 2.

[0052] In step 1, the temperature difference between the outlet temperature of each outlet and the target temperature is calculated based on the outlet temperature of that outlet.

[0053] In step 2, the opening value of the hybrid damper is determined according to the product of the temperature difference at the air outlet and a preset parameter.

[0054] In this embodiment, in addition to directly calculating the opening value of the hybrid damper, it is also necessary to adjust the opening value of the hybrid damper according to the temperature regulation control mode. In different temperature regulation control modes, different configurations of the opening value can be shown in the following example.

[0055] In one example, when the temperature adjustment control mode is one of cooling by a compressor, heating by a heater, or heating by a compressor with the compressor rotation speed exceeding the minimum rotation speed at which the compressor can operate, a specific method for calculating the opening value includes steps 1 to 3.

[0056] In step 1, a first temperature region having the greatest temperature adjustment demand is determined according to the temperature adjustment demand of each temperature region.

[0057] In this step, the in-vehicle terminal can acquire the blowout volume for each temperature region. The in-vehicle terminal can determine the temperature adjustment demand for each temperature region according to the blowout volume. The in-vehicle terminal can determine the temperature region with the greatest temperature adjustment demand by comparing the temperature adjustment demand for each temperature region. The in-vehicle terminal can determine the temperature region with the greatest temperature adjustment demand as a first temperature region, and the temperature regions excluding the first temperature region as other temperature regions.

[0058] In step 2, the opening value of the hybrid damper in the first temperature region is set to a fixed value.

[0059] In this step, the fixed value includes 0 and 100%. When the temperature regulation control mode is heating, the fixed value can be set to 100%, i.e., full heating. When the temperature regulation control mode is cooling, the fixed value can be set to 0, i.e., full cooling.

[0060] In step 3, the opening degree values ​​of the hybrid dampers in the other temperature regions excluding the first temperature region are adjusted in accordance with the target temperature and the blowout temperatures in the other temperature regions excluding the first temperature region.

[0061] In this step, the in-vehicle terminal can calculate the damper opening value for each temperature region using the method shown in the previous example for calculating the hybrid damper opening value based on the blown temperature and the target temperature.

[0062] For example, if only cooling is needed in the passenger compartment, the temperature adjustment control mode is compressor cooling. The in-vehicle terminal can determine the temperature region in the multi-temperature region air-conditioning box that has the greatest cooling need as the first temperature region. The in-vehicle terminal can fix the hybrid damper corresponding to the first temperature region to the full cooling position. At the same time, the in-vehicle terminal adjusts and controls the opening value of the hybrid damper for the other temperature regions according to the outlet temperature of the outlet for the other temperature regions and the target temperature.

[0063] For example, if there is a heating need in the passenger compartment and the passenger compartment is heated using a separate PTC, the in-vehicle terminal can determine the temperature region in the multi-temperature region air conditioning box with the greatest heating need as the first temperature region. The in-vehicle terminal can fix the hybrid damper corresponding to the first temperature region to the full heating position. At the same time, the in-vehicle terminal can control the PTC output power of the first temperature region so that the outlet temperature corresponding to the first temperature region reaches the target outlet temperature. For the hybrid dampers of other temperature regions, the in-vehicle terminal adjusts and controls their opening degrees according to the outlet temperatures of the outlets of the other temperature regions and the target temperatures.

[0064] Furthermore, for example, if there is a need for heating in the passenger compartment and both the PTC and the compressor are used to heat the passenger compartment, the on-board terminal can determine the temperature region in the multi-temperature region air conditioning box with the greatest heating need as the first temperature region. The on-board terminal can fix the hybrid damper corresponding to the first temperature region to the full heating position. At the same time, the compressor operates at the upper limit rotation speed set for this operating condition, and the on-board terminal can control the PTC output power so that the outlet temperature corresponding to the first temperature region reaches the target outlet temperature. For the hybrid dampers in other temperature regions, the on-board terminal adjusts and controls their opening degrees according to the outlet temperatures of the outlets in the other temperature regions and the target temperatures.

[0065] Furthermore, for example, if there is a heating need in the passenger compartment and the passenger compartment is heated using a separate compressor, and the compressor rotation speed is not the minimum operable rotation speed, for example, if the compressor rotation speed exceeds 850 rpm, the in-vehicle terminal can determine the temperature region in the multi-temperature region air conditioning box where heating is most needed as the first temperature region. The in-vehicle terminal can fix the hybrid damper corresponding to the first temperature region to the full heating position. By controlling the compressor rotation speed, the in-vehicle terminal can ensure that the outlet temperature corresponding to the first temperature region reaches the target outlet temperature. At the same time, the in-vehicle terminal adjusts and controls the opening degree of the hybrid damper for the other temperature regions according to the outlet temperatures of the outlets for the other temperature regions and the target temperatures.

[0066] In another example, when the temperature adjustment control mode is heating by residual heat from the motor and / or battery or heating by the compressor and the compressor rotation speed is equal to or lower than the minimum operable speed of the compressor, the opening degree of the hybrid damper can be determined according to the target temperature and the outlet temperature of each temperature range, thereby completing the adjustment of the hybrid damper for each temperature range. When the compressor rotation speed is equal to or lower than the minimum operable speed of the compressor, the compressor rotation speed may be set to 850 rpm.

[0067] For example, if there is a need for heating in the passenger compartment and the passenger compartment is heated using residual heat from the motor and / or battery, the in-vehicle terminal does not need to directly limit the opening degree of any hybrid damper. The opening degree value of each hybrid damper in the vehicle can be calculated based on the outlet temperature and the target temperature, thereby adjusting the opening degree of each hybrid damper so that the outlet temperature of each outlet reaches the target temperature.

[0068] Furthermore, for example, if there is a need for heating in the passenger compartment and the passenger compartment is heated using only the compressor, if a preset condition is met, the compressor rotation speed is fixed to the lowest possible rotation speed and the opening degree of any hybrid damper is not directly limited. The opening value of each hybrid damper in the vehicle can be calculated based on the outlet temperature and the target temperature, and the opening degree of each hybrid damper is adjusted so that the outlet temperature of each outlet reaches the target temperature. The preset condition can include a condition that the duration of the compressor rotation speed exceeds a first threshold value and a condition that the difference between the outlet temperature and the target temperature is greater than a second threshold value.

[0069] In the heat pump system control method for a multi-temperature zone air conditioning box provided by the present application, an on-board terminal can acquire the vehicle's temperature control mode, target temperature, and temperature control demand and outlet temperature for each temperature zone of the vehicle. The vehicle terminal can adjust the opening value of the hybrid damper for each temperature zone according to the temperature control mode, target temperature, and temperature control demand and outlet temperature for each temperature zone so that the outlet temperature for each temperature zone reaches the target temperature. This application achieves accurate control of the heating / cooling needs of the passenger compartment by combining a means for directly limiting the opening value of the hybrid damper according to the temperature control mode and a means for calculating the opening value of the hybrid damper based on the difference between the outlet temperature and the target temperature. At the same time, this application uses a temperature sensor located at the air outlet instead of the temperature sensor located behind the heater core in the prior art, thereby reducing costs and achieving the goal of energy conservation.

[0070] Figure 3 shows a structural schematic diagram of a heat pump system control device for a multi-temperature region air conditioning box provided by one embodiment of the present application. As shown in Figure 3, the heat pump system control device 10 for a multi-temperature region air conditioning box in this embodiment is used to implement corresponding operations on an in-vehicle terminal in any of the above-mentioned method embodiments, and the heat pump system control device 10 for a multi-temperature region air conditioning box in this embodiment includes an acquisition module 11 and a control module 12.

[0071] The acquisition module 11 is used to acquire the vehicle's temperature adjustment control mode, target temperature, temperature adjustment demand and outlet temperature of each temperature zone of the vehicle, and the outlet temperature is measured by a temperature sensor at the outlet corresponding to the temperature zone.

[0072] The control module 12 is used to adjust the opening value of the hybrid damper for each temperature region according to the temperature adjustment control mode, the target temperature, and the temperature adjustment demand and blowing temperature for each temperature region so that the blowing temperature for each temperature region reaches the target temperature.

[0073] In one example, the temperature regulation control modes include one or more of the following modes: compressor cooling, heater heating, motor and / or battery residual heat heating, and compressor heating.

[0074] In one example, when the temperature adjustment control mode is one of cooling by the compressor, heating by the heater, and heating by the compressor with the compressor speed higher than the minimum speed at which the compressor can operate, the control module 12 specifically: determining a first temperature region having the greatest temperature adjustment demand among the temperature regions according to the temperature adjustment demand; setting the opening value of the hybrid damper in the first temperature region to a fixed value; The opening degree value of the hybrid damper in the other temperature regions excluding the first temperature region is adjusted according to the target temperature and the blowout temperature in the other temperature regions excluding the first temperature region.

[0075] In one example, when the temperature adjustment control mode is heating by residual heat of the motor and / or battery or heating by the compressor and the compressor rotation speed is equal to or lower than the minimum rotation speed at which the compressor can operate, the control module 12 specifically: It is used to adjust the opening value of the hybrid damper for each temperature region according to the target temperature and the blown air temperature for each temperature region.
