Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more particularly to methods, systems, devices, and media for heat distribution in the passenger compartment and battery of a vehicle. Background Technology

[0002] In the thermal management system of new energy vehicles, passenger cabin comfort and battery temperature safety are two core objectives. In winter or low-temperature environments, heat pump systems or positive temperature coefficient (PTC) heaters serve as heat sources to provide heat to the passenger cabin and battery. When both the passenger cabin and battery require heating simultaneously, heat is distributed via water valves. Due to limited heat source capacity, current technologies cannot dynamically adjust based on real-time heat load. This may result in the battery temperature not rising quickly enough, affecting re-discharge performance, or insufficient heating of the passenger cabin, impacting user experience. Therefore, areas for improvement exist. Summary of the Invention

[0003] This invention provides a method, system, device, and medium for heat distribution in the passenger compartment and battery of a vehicle, in order to solve the technical problem in the prior art that the heat distribution cannot be dynamically adjusted according to the real-time heat load, resulting in insufficient heating of the passenger compartment.

[0004] This invention provides a heat distribution method for the passenger compartment and battery of a vehicle. The passenger compartment water circuit and the battery water circuit are connected to a regulating valve. By controlling the opening of the regulating valve, the output hot water from the heater flows proportionally into the passenger compartment water circuit and the battery water circuit, respectively. The method includes:

[0005] Real-time monitoring of the vehicle's external ambient temperature, the heat exchange temperature of the heat exchanger in the cabin's water circuit, and the breathing point temperature of the driver's side / passenger side passengers;

[0006] Obtain the target temperature set on the heat exchanger and calculate the temperature deviation between the target temperature and the heat exchange temperature;

[0007] Obtain the temperature difference range corresponding to the ambient temperature, compare the deviation temperature with the temperature difference range, and obtain a first comparison result;

[0008] Obtain the desired temperature range corresponding to the ambient temperature and the preset vehicle air conditioning temperature, compare the breathing point temperature with the desired temperature range, and obtain a second comparison result;

[0009] Based on the first comparison result and the second comparison result, the opening degree of the regulating valve is controlled until the deviation temperature is within the temperature difference range and the breathing point temperature is within the desired temperature range.

[0010] In one embodiment of the present invention, the step of controlling the opening of the regulating valve based on the first comparison result and the second comparison result until the deviation temperature is within the temperature difference range and the breathing point temperature is within the desired temperature range includes:

[0011] When the first comparison result is that the deviation temperature is equal to the midpoint of the temperature difference range, and the second comparison result is that the breathing point temperature is equal to the midpoint of the desired temperature range, the current opening of the regulating valve is maintained.

[0012] In one embodiment of the present invention, the step of controlling the opening of the regulating valve based on the first comparison result and the second comparison result until the deviation temperature is within the temperature difference range and the breathing point temperature is within the desired temperature range includes:

[0013] When the first comparison result is that the deviation temperature is greater than or equal to the maximum value of the temperature difference range, and / or the second comparison result is that the breathing point temperature is less than the minimum value of the desired temperature range, the opening of the regulating valve is reduced according to the adjustment speed to adjust the heat exchange temperature and the breathing point temperature.

[0014] Continuously monitor the breathing point temperature and the heat exchange temperature in real time, and calculate the deviation temperature:

[0015] When the deviation temperature is equal to the midpoint of the temperature range and the breathing point temperature is equal to the midpoint of the desired temperature range, stop adjusting the regulating valve.

[0016] Otherwise, continue to reduce the opening of the regulating valve according to the adjustment speed until the deviation temperature equals the midpoint of the temperature range and the breathing point temperature equals the midpoint of the desired temperature range.

[0017] In one embodiment of the present invention, the step of controlling the opening of the regulating valve based on the first comparison result and the second comparison result until the deviation temperature is within the temperature difference range and the breathing point temperature is within the desired temperature range includes:

[0018] When the first comparison result is that the deviation temperature is less than the minimum value of the temperature difference range, and the second comparison result is that the breathing point temperature is greater than or equal to the maximum value of the desired temperature range, the opening of the regulating valve is increased according to the adjustment speed to adjust the heat exchange temperature and the breathing point temperature.

[0019] Continuously monitor the breathing point temperature and the heat exchange temperature in real time, and calculate the deviation temperature:

[0020] When the deviation temperature is equal to the midpoint of the temperature range and the breathing point temperature is equal to the midpoint of the desired temperature range, stop adjusting the regulating valve.

[0021] Otherwise, continue to increase the opening of the regulating valve according to the adjustment speed until the deviation temperature equals the midpoint of the temperature range and the breathing point temperature equals the midpoint of the desired temperature range.

[0022] In one embodiment of the present invention, the opening degree of the regulating valve is 9% to 90%. The opening degree of the regulating valve reflects the distribution ratio of the output hot water flow of the heater between the battery water circuit and the crew cabin water circuit. Reducing the opening degree of the regulating valve increases the distribution ratio of the crew cabin water circuit and decreases the distribution ratio of the battery water circuit.

[0023] In one embodiment of the present invention, the magnitude of the adjustment speed is related to the opening position of the regulating valve. When the regulating valve increases from the middle opening to the maximum opening, or decreases from the middle opening to the minimum opening, the adjustment speed gradually decreases, and the adjustment speed reaches the minimum value when the regulating valve reaches the maximum opening or the minimum opening.

[0024] In one embodiment of the present invention, the magnitude of the adjustment speed is positively correlated with the temperature of the battery module in the battery water circuit, and the magnitude of the adjustment speed is negatively correlated with the target temperature.

[0025] This invention also proposes a heat distribution system for the passenger compartment and battery of a vehicle. The passenger compartment water circuit and the battery water circuit are connected to a regulating valve. By controlling the opening of the regulating valve, the output hot water from the heater flows proportionally into the passenger compartment water circuit and the battery water circuit, respectively. The system is characterized by comprising:

[0026] The data acquisition unit is used to collect real-time ambient temperature outside the vehicle, heat exchange temperature of the heat exchanger in the water circuit of the cabin, and breathing point temperature of the driver's side / passenger side passengers.

[0027] The calculation unit is used to obtain the target temperature set on the heat exchanger and calculate the temperature deviation between the target temperature and the heat exchange temperature.

[0028] The first comparison unit is used to obtain the temperature difference range corresponding to the ambient temperature, compare the deviation temperature with the temperature difference range, and obtain a first comparison result.

[0029] The second comparison unit is used to obtain the desired temperature range corresponding to the ambient temperature and the preset vehicle air conditioning temperature, compare the breathing point temperature with the desired temperature range, and obtain a second comparison result.

[0030] The control unit is used to control the opening of the regulating valve based on the first comparison result and the second comparison result until the deviation temperature is within the temperature difference range and the breathing point temperature is within the desired temperature range.

[0031] The present invention also proposes an electronic device, the electronic device comprising:

[0032] One or more processors;

[0033] A storage device for storing one or more programs that, when executed by one or more processors, cause the electronic device to implement the heat distribution method for the passenger compartment and battery of the vehicle as described in any of the preceding embodiments.

[0034] The present invention also proposes a computer-readable storage medium having a computer program stored thereon, which, when executed by a computer processor, causes the computer to perform the heat distribution method for the passenger compartment and battery of any of the above-described vehicles.

[0035] The beneficial effects of this invention are as follows: This invention proposes a heat distribution system, device, and medium for the passenger compartment and battery of a vehicle. It collects real-time data on the ambient temperature outside the vehicle, the heat exchange temperature of the heat exchanger in the passenger compartment's water circuit, and the breathing point temperature of the driver / passenger side passengers. The deviation between the target temperature set on the heat exchanger and the heat exchange temperature is compared with a preset temperature difference range to obtain a first comparison result, which indicates whether control of the regulating valve is needed. A second comparison result is obtained by comparing the breathing point temperature with the ambient temperature and the desired temperature range corresponding to the preset vehicle air conditioning temperature. This second comparison result also indicates whether control of the regulating valve is needed. Subsequently, based on the first and second comparison results, the opening of the regulating valve is controlled until the deviation temperature is within the temperature difference range and the breathing point temperature is within the desired temperature range, thereby achieving a temperature equilibrium within the passenger compartment.

[0042] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0043] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0044] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0045] Please see Figure 1 and Figure 2 This invention proposes a method, system, device, and medium for heat distribution in the passenger compartment and battery of a vehicle, applicable to the thermal management field of new energy vehicles. This invention departs from the traditional fixed-ratio heat distribution method, dynamically adjusting the opening of water valves by real-time identification of the heat load requirements of the passenger compartment and battery, thus more accurately meeting the temperature control targets of each module and avoiding heat waste or insufficient heating. Detailed descriptions are provided below using specific embodiments.

[0046] Please see Figure 1 and Figure 2 In one embodiment of the present invention, a heat distribution method for the passenger compartment and battery of a vehicle is proposed. The passenger compartment water circuit 20 and the battery water circuit 10 in the vehicle are connected to a regulating valve 30. By controlling the opening of the regulating valve 30, the hot water output from the heater flows into the passenger compartment water circuit 20 and the battery water circuit 10 in proportion respectively.

[0047] Specifically, such as Figure 1 As shown, regulating valve 30 is a three-way proportional regulating valve. The opening degree of the three-way proportional regulating valve reflects the distribution ratio of the heater's output hot water flow between the battery water circuit 10 and the crew cabin water circuit 20. Decreasing the opening degree of the regulating valve increases the distribution ratio of the crew cabin water circuit 20 and decreases the distribution ratio of the battery water circuit 10. For example, if the opening degree of regulating valve 30 is x%, then x% of the heat from the heater's output hot water flow is supplied to the battery water circuit 10, and (100-x)% of the heat from the heater's output hot water flow is supplied to the crew cabin water circuit 20. When regulating valve 30 is open, the battery water circuit 10 and the crew cabin water circuit 20 are connected.

[0048] The heat distribution method for the vehicle's passenger compartment and battery may include the following steps.

[0049] Step S10: Real-time acquisition of the ambient temperature outside the vehicle, the heat exchange temperature of the heat exchanger in the cabin water circuit 20, and the breathing point temperature of the driver's side / passenger side passengers.

[0050] Specifically, the current outside air temperature is obtained by an ambient temperature sensor located at the front of the vehicle, which reflects the climate conditions in which the vehicle is located. At the same time, the actual operating temperature of the heat exchanger, i.e., the heat exchange temperature, is continuously monitored by a temperature sensor installed on the surface of the heat exchanger in the crew compartment water circuit 20. This temperature directly reflects the real-time heat exchange status of the crew compartment heating system.

[0051] In addition, breathing point temperature sensors located near the air vents on the driver's or passenger's side in the cockpit collect the air temperature in the occupants' breathing area. This temperature is used to assess the perceived comfort level within the cabin. The simultaneous acquisition of these three temperature parameters provides real-time, multi-dimensional environmental and system status input for subsequent heat distribution decisions.

[0052] Step S20: Obtain the target temperature set on the heat exchanger and calculate the temperature deviation between the target temperature and the heat exchange temperature.

[0053] Specifically, the system acquires the target temperature set on the heat exchanger and calculates the temperature deviation between the target temperature and the heat exchange temperature. The target temperature is the ideal temperature value that the heat exchanger is expected to achieve, calculated by the vehicle's air conditioning control system based on user settings or automatic mode.

[0054] The preset target temperature is read from the air conditioning controller and compared with the heat exchange temperature collected in real time in step S10. The difference between the two is obtained by subtraction, which is the deviation temperature. This deviation temperature quantifies the gap between the current cabin heating effect and the expected effect. A larger deviation temperature indicates that the actual temperature is lower than the target, and more heat is needed; a smaller deviation temperature indicates that the actual temperature is close to or exceeds the target, and the heat demand is reduced.

[0055] Step S30: Obtain the temperature difference range corresponding to the ambient temperature, compare the deviation temperature with the temperature difference range, and obtain the first comparison result.

[0056] Specifically, the temperature difference range corresponding to the ambient temperature is obtained, and the deviation temperature calculated in step S20 is compared with this temperature difference range to obtain the first comparison result. Regarding the mapping relationship data between ambient temperature and temperature difference range, this temperature difference range defines the threshold range for judging whether the heating state of the heat exchanger is normal under different ambient temperatures.

[0057] Secondly, based on the ambient temperature collected in step S10, the mapping relationship is queried to determine the specific temperature difference range corresponding to the current environment. Then, the calculated deviation temperature is compared with the queried temperature difference range to determine whether the deviation temperature is below the lower limit of the range, within the range, or above the upper limit of the range, thus forming the first comparison result. The first comparison result is used to indicate whether the thermal load status of the crew cabin water circuit 20 requires limiting the opening of the regulating valve 30.

[0058] Table 1. Mapping Relationship between Ambient Temperature and Temperature Difference Range

[0059]

[0060] In Table 1, when the ambient temperature is -20℃, the temperature difference range is 7℃ to 13℃.

[0061] Step S40: Obtain the desired temperature range corresponding to the ambient temperature and the preset vehicle air conditioning temperature, compare the breathing point temperature with the desired temperature range, and obtain a second comparison result.

[0062] Specifically, the desired temperature range corresponding to the ambient temperature and the preset vehicle air conditioning temperature is obtained, and the breathing point temperature collected in step S10 is compared with the desired temperature range to obtain a second comparison result. The mapping relationship data between the ambient temperature and the desired temperature range corresponding to the preset vehicle air conditioning temperature defines the comfortable range of the occupant's breathing point temperature, i.e., the desired temperature range, under different combinations of ambient temperature and preset air conditioning temperature.

[0063] Based on the ambient temperature collected in step S10 and the vehicle air conditioning temperature set by the user, this mapping relationship is queried to determine the expected range of the breathing point temperature under the current operating conditions. Next, the real-time collected breathing point temperature is compared with the queried expected temperature range to determine whether the breathing point temperature is below the lower limit of the range, within the range, or above the upper limit of the range, thus forming a second comparison result. This result is used to indicate whether the cabin comfort status requires limiting the opening of the regulating valve 30.

[0064] Table 2. Minimum values ​​of the desired temperature range corresponding to ambient temperature and preset vehicle air conditioning temperature.

[0065]

[0066] Table 3. Maximum values ​​of the desired temperature range corresponding to ambient temperature and preset vehicle air conditioning temperature

[0067]

[0068] In Tables 3 and 4, when the ambient temperature is -20℃ and the vehicle air conditioning temperature is 16℃, the corresponding desired temperature range is 9℃~12℃.

[0069] Step S50: Based on the first comparison result and the second comparison result, control the opening of the regulating valve 30 until the deviation temperature is within the temperature difference range and the breathing point temperature is within the desired temperature range.

[0070] Specifically, if the first comparison result indicates that the deviation temperature is greater than the upper limit of the temperature difference range, and / or the second comparison result indicates that the breathing point temperature is lower than the lower limit of the desired temperature range, then it is determined that the heat flow to the battery needs to be restricted to prioritize meeting the needs of the crew cabin, thereby reducing the opening of the regulating valve 30. If the first comparison result indicates that the deviation temperature is less than the lower limit of the temperature difference range, and the second comparison result indicates that the breathing point temperature is higher than the upper limit of the desired temperature range, then the system determines that the heat demand of the crew cabin has been basically met, and the opening of the regulating valve 30 can be increased to allocate more heat to the battery.

[0071] Through closed-loop control, temperature changes are continuously monitored and the opening of the regulating valve is dynamically adjusted to eventually stabilize at a balance: the cabin heating meets basic requirements (temperature deviation is within a reasonable range), while the remaining heat is effectively distributed to the battery for heating or insulation.

[0072] In one embodiment of the present invention, step S50, which controls the opening of the regulating valve 30 based on the first comparison result and the second comparison result until the deviation temperature is within the temperature difference range and the breathing point temperature is within the desired temperature range, may include the following steps.

[0073] Step S510: When the first comparison result is that the deviation temperature is equal to the midpoint of the temperature difference range, and the second comparison result is that the breathing point temperature is equal to the midpoint of the desired temperature range, maintain the current opening of the regulating valve 30.

[0074] Specifically, when the first comparison result is that the deviation temperature equals the midpoint of the temperature difference range, and the second comparison result is that the breathing point temperature equals the midpoint of the desired temperature range, the system will maintain the current opening of the regulating valve 30. The deviation temperature equaling the midpoint of the temperature difference range indicates that the difference between the actual operating temperature of the heat exchanger and the target temperature is within the preset optimal range. This means that the heating needs of the cabin are precisely met, without being insufficient or excessive. Simultaneously, the breathing point temperature equaling the midpoint of the desired temperature range indicates that the perceived temperature in the occupant's breathing area is at the center of the comfort zone, and the occupant's thermal comfort has reached an optimal state.

[0075] At this point, it is determined that the current opening of the regulating valve 30 has achieved the most reasonable heat distribution ratio between the cabin and the battery. Any adjustment to the opening may disrupt this balance, leading to either a decrease in cabin comfort or a reduction in battery heating efficiency. Therefore, the heat distribution controller will maintain the existing control commands and will not send any action signals to the drive motor of the regulating valve 30, keeping the opening of the regulating valve 30 stable at the current value. The system enters a stable maintenance phase until external conditions or target settings change, triggering new control requirements.

[0076] In one embodiment of the present invention, step S50, which controls the opening of the regulating valve 30 based on the first comparison result and the second comparison result until the deviation temperature is within the temperature difference range and the breathing point temperature is within the desired temperature range, may include the following steps.

[0077] When the first comparison result is that the deviation temperature is greater than or equal to the maximum value of the temperature difference range, and / or the second comparison result is that the breathing point temperature is less than the minimum value of the desired temperature range, the opening of the regulating valve 30 is reduced according to the adjustment speed to adjust the heat exchange temperature and the breathing point temperature.

[0078] Specifically, when the first comparison result is that the deviation temperature is greater than or equal to the maximum value of the temperature difference range, or the second comparison result is that the breathing point temperature is less than the minimum value of the expected temperature range, or both of these situations occur simultaneously, the system will start to reduce the opening of the regulating valve 30 according to the preset adjustment speed, thereby adjusting the heat exchange temperature and the breathing point temperature.

[0079] This situation indicates that the system has detected a risk of insufficient heating in the crew cabin, specifically, the actual temperature of the heat exchanger is significantly lower than the target temperature, or the perceived temperature in the occupants' breathing area is below the lower limit of the comfort range, or both. To prioritize the comfort needs of the crew cabin, the heat flowing to the battery water circuit 10 must be reduced, thereby allocating more heat output to the crew cabin water circuit 20. Based on the internally stored adjustment speed mapping relationship, a suitable rate of reducing the opening is determined, and a command is sent to the drive motor of the regulating valve 30 to slowly begin rotating towards the closing direction.

[0080] The breathing point temperature and the heat exchange temperature are continuously monitored in real time, and the deviation temperature is calculated.

[0081] Specifically, while reducing the opening of regulating valve 30, the system continuously and in real time monitors the breathing point temperature and heat exchange temperature, and recalculates the real-time deviation temperature based on the latest collected heat exchange temperature and target temperature. This is a closed-loop feedback control process that continuously acquires the latest temperature sensor readings to ensure that the control decisions are based on the most realistic current state of the system, thereby providing precise guidance for the operation of regulating valve 30.

[0082] When the deviation temperature is equal to the midpoint of the temperature range and the breathing point temperature is equal to the midpoint of the desired temperature range, the adjustment of the regulating valve 30 is stopped.

[0083] Specifically, the newly calculated deviation temperature is compared with the temperature difference range, and the newly collected breathing point temperature is compared with the desired temperature range, performing a new round of logical judgment. When it is detected that the deviation temperature is equal to the midpoint of the temperature difference range, and the breathing point temperature is also equal to the midpoint of the desired temperature range, it indicates that the heating and comfort requirements of the cabin have been optimally met through the previous opening reduction operation, and the system has reached a new, ideal thermal equilibrium state. At this time, the adjustment of the regulating valve 30 will be immediately stopped, stabilizing the regulating valve 30 at its current opening position.

[0084] Otherwise, continue to reduce the opening of the regulating valve 30 according to the adjustment speed until the deviation temperature is equal to the midpoint of the temperature range and the breathing point temperature is equal to the midpoint of the desired temperature range.

[0085] Specifically, if the conditions in step S522 are not met—that is, the deviation temperature has not reached the midpoint of the temperature difference range, or the breathing point temperature has not reached the midpoint of the desired temperature range, or neither—then it is determined that the cabin's thermal requirements are not yet fully met. The opening of the regulating valve 30 will continue to decrease at the preset adjustment rate. This continuous adjustment process will cycle through the monitoring, calculation, judgment, and control procedures until the equilibrium condition of the deviation temperature equaling the midpoint of the temperature difference range and the breathing point temperature equaling the midpoint of the desired temperature range is finally met, at which point the adjustment will terminate.

[0086] In one embodiment of the present invention, step S50, which controls the opening of the regulating valve 30 based on the first comparison result and the second comparison result until the deviation temperature is within the temperature difference range and the breathing point temperature is within the desired temperature range, may include the following steps.

[0087] When the first comparison result is that the deviation temperature is less than the minimum value of the temperature difference range, and the second comparison result is that the breathing point temperature is greater than or equal to the maximum value of the desired temperature range, the opening of the regulating valve 30 is increased according to the adjustment speed to adjust the heat exchange temperature and the breathing point temperature.

[0088] Specifically, when the first comparison result is that the deviation temperature is less than the minimum value of the temperature difference range, and the second comparison result is that the breathing point temperature is greater than or equal to the maximum value of the desired temperature range, the opening of the regulating valve 30 will be increased according to the preset adjustment speed to change the heat distribution, thereby adjusting the heat exchange temperature and the breathing point temperature.

[0089] The above indicates that the crew cabin is in or near a superheated state, with the actual temperature of the heat exchanger very close to or even exceeding the target temperature, and the occupant's breathing point temperature reaching or exceeding the upper limit of the comfort range. This means that the heat supplied to the crew cabin is sufficient or even slightly surplus, allowing more heat to be allocated to the battery water circuit 10. The controller will determine a rate of increase in opening based on the built-in strategy and instruct the regulating valve 30 to move in the opening direction.

[0090] The breathing point temperature and the heat exchange temperature are continuously monitored in real time, and the deviation temperature is calculated.

[0091] Specifically, as the regulating valve begins to increase its opening by 30 degrees, the readings of the breathing point temperature sensor and the heat exchanger temperature sensor are continuously and in real time collected. Using the latest obtained heat exchange temperature and the set target temperature, a new real-time deviation temperature is calculated again.

[0092] When the deviation temperature is equal to the midpoint of the temperature range and the breathing point temperature is equal to the midpoint of the desired temperature range, the adjustment of the regulating valve 30 is stopped.

[0093] Specifically, the latest obtained deviation temperature is compared with the temperature difference range, and the latest collected breathing point temperature is compared with the desired temperature range. When it is confirmed that the current deviation temperature is equal to the midpoint of the temperature difference range, and the current breathing point temperature is also equal to the midpoint of the desired temperature range, it indicates that the thermal state and comfort of the cabin have returned to the ideal optimal balance point. At this time, an instruction will be immediately issued to stop further adjustment of the regulating valve 30 and lock its opening at the current value.

[0094] Otherwise, continue to increase the opening of the regulating valve 30 according to the adjustment speed until the deviation temperature is equal to the midpoint of the temperature range and the breathing point temperature is equal to the midpoint of the desired temperature range.

[0095] Specifically, if the conditions in step S532 are not simultaneously met—the deviation temperature equal to the midpoint of the temperature difference range and the breathing point temperature equal to the midpoint of the desired temperature range—then it is determined that the equilibrium state has not yet been achieved. The controller will continue to instruct the regulating valve 30 to further increase its opening according to the preset adjustment speed. This "monitoring-calculation-judgment-execution" cyclical control process will continue until the ideal equilibrium state defined in step S532 is finally reached, at which point the operation of increasing the opening of the regulating valve 30 will terminate.

[0096] In one embodiment of the present invention, the opening degree of the regulating valve 30 is 9% to 90%. The opening degree of the regulating valve 30 reflects the distribution ratio of the output hot water flow of the heater between the battery water circuit 10 and the crew cabin water circuit 20. Reducing the opening degree of the regulating valve 30 increases the distribution ratio of the crew cabin water circuit 20 and decreases the distribution ratio of the battery water circuit 10.

[0097] In one embodiment of the present invention, when the regulating valve 30 is adjusted toward the middle opening, the adjustment speed gradually increases; when the regulating valve 30 is adjusted from the middle opening to both sides, the adjustment speed gradually decreases, and the adjustment speed is the minimum at the maximum or minimum opening.

[0098] That is, the adjustment speed of the regulating valve 30 is related to the opening position of the regulating valve 30. When the regulating valve 30 increases from the middle opening to the maximum opening, or decreases from the middle opening to the minimum opening, the adjustment speed gradually decreases, and the adjustment speed reaches the minimum value when the regulating valve 30 reaches the maximum opening or the minimum opening.

[0099] Specifically, when controlling the regulating valve to a 30° opening, its adjustment speed will dynamically change according to the valve's current position. As the valve moves from the middle opening to the maximum or minimum opening, the speed will gradually slow down, and will drop to the minimum when approaching the limit position, thereby avoiding impact and achieving smooth and precise control.

[0100] In one embodiment of the present invention, the adjustment speed of the regulating valve 30 is positively correlated with the temperature of the battery module in the battery water circuit 10, and the adjustment speed is negatively correlated with the target temperature.

[0101] Specifically, the adjustment speed is affected by both battery temperature and target temperature. The higher the battery temperature, the faster the adjustment speed to quickly respond to battery heating needs. The higher the target temperature, the slower the adjustment speed to prioritize cabin comfort. This two-way adjustment achieves intelligent optimization of heat distribution.

[0102] Please see Figure 3 The present invention also proposes a heat distribution system 100 for the passenger compartment and battery of a vehicle. The passenger compartment water circuit 20 and the battery water circuit 10 in the vehicle are connected to a regulating valve 30. By controlling the opening of the regulating valve 30, the hot water output from the heater flows into the passenger compartment water circuit 20 and the battery water circuit 10 in proportion. The heat distribution system 100 includes a data acquisition unit 110, a calculation unit 120, a first comparison unit 130, a second comparison unit 140 and a control unit 150.

[0103] The data acquisition unit 110 is used to collect the ambient temperature outside the vehicle, the heat exchange temperature of the heat exchanger in the water circuit of the cabin, and the breathing point temperature of the driver's side / passenger side passengers in real time.

[0104] The calculation unit 120 is used to obtain the target temperature set on the heat exchanger and calculate the temperature deviation between the target temperature and the heat exchange temperature.

[0109] The memory 210 includes at least one type of readable storage medium, such as flash memory, portable hard drive, multimedia card, card-type memory (e.g., SD or DX memory), magnetic memory, magnetic disk, optical disk, etc. In some embodiments, the memory 210 can be an internal storage unit of the electronic device 200, such as the portable hard drive of the electronic device 200. In other embodiments, the memory 210 can be an external storage device of the electronic device 200, such as a plug-in portable hard drive, smart media card (SMC), secure digital card (SD), flash card, etc., equipped on the electronic device 200. Furthermore, the memory 210 can include both internal and external storage units of the electronic device 200. The memory 210 can be used not only to store application software and various types of data installed on the electronic device 200, such as codes for passenger compartment and battery heat distribution in a vehicle, but also to temporarily store data that has been output or will be output.

[0110] In some embodiments, processor 220 may be composed of integrated circuits, such as a single packaged integrated circuit or multiple integrated circuits packaged with the same or different functions, including combinations of one or more central processing units (CPUs), microprocessors, digital processing chips, graphics processors, and various control chips. Processor 220 is the control unit of the electronic device 200, connecting various components of the entire electronic device 200 via various interfaces and lines. It executes programs or modules stored in the memory 210 (e.g., heat distribution programs for the vehicle's passenger compartment and battery), and calls data stored in the memory 210 to perform various functions and process data of the electronic device 200.

[0111] The processor 220 executes the operating system of the electronic device 200 and various installed applications. The processor 220 executes the applications to implement the steps in the heat distribution method for the passenger compartment and battery of the aforementioned vehicle.

[0112] For example, the computer program may be divided into one or more modules, which are stored in the memory 210 and executed by the processor 220 to complete this application. The one or more modules may be a series of computer program instruction segments capable of performing specific functions, which describe the execution process of the computer program in the electronic device 200. For example, the computer program may be divided into a data acquisition unit 110, a calculation unit 120, a first comparison unit 130, a second comparison unit 140, and a control unit 150.

[0113] The integrated unit implemented as a software functional module described above can be stored in a computer-readable storage medium, which can be non-volatile or volatile. The software functional module, stored in the storage medium, includes several instructions to cause a computer device (which may be a personal computer, computer equipment, or network device, etc.) or processor to perform some functions of the heat distribution method for the passenger compartment and battery of the vehicle described in the various embodiments of this application.

[0114] This invention proposes a method, system, device, and medium for heat distribution in the vehicle's passenger compartment and battery. It involves real-time acquisition of the external ambient temperature, the heat exchange temperature of the heat exchanger in the passenger compartment's water circuit, and the breathing point temperature of the driver / passenger side. The deviation between the target temperature set on the heat exchanger and the heat exchange temperature is compared with a preset temperature difference range to obtain a first comparison result, indicating whether control of the regulating valve is needed. A second comparison result is obtained by comparing the breathing point temperature with the ambient temperature and the desired temperature range corresponding to the preset vehicle air conditioning temperature. This second comparison result also indicates whether control of the regulating valve is needed. Subsequently, based on the first and second comparison results, the opening of the regulating valve is controlled until the deviation temperature is within the temperature difference range and the breathing point temperature is within the desired temperature range, thereby achieving a temperature equilibrium within the passenger compartment.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
