Abstract

This application discloses a method and related device for controlling in-vehicle temperature, relating to the field of automotive control technology. The solution includes collecting vehicle operating environment information, determining a target heating component and its corresponding target temperature value, as well as the target heating power of the air conditioner, based on the collected information. Both the target heating power and the target temperature value are positively correlated with the initial heat required to reach a specified in-vehicle ambient temperature. Finally, the temperature of the target heating component is controlled based on its target temperature value, and simultaneously, the heating power of the air conditioner is controlled based on the target heating power. In a coordinated control scenario, since the internal heating component is already activated to conduct heat to the user's local area, the local temperature can be quickly increased.

The target temperature value of the heating component and the target heating power of the air conditioner are both positively correlated with the first energy required to reach the specified in-vehicle ambient temperature. Finally, the temperature of the target heating component is controlled based on its target temperature value, and simultaneously, the air outlet parameters of the air conditioner, such as outlet temperature and air volume, are controlled based on the target heating power. In the coordinated control scenario, the internal heating components are already activated to conduct heat to the user's local area through contact heating, which can quickly raise the user's local temperature. Therefore, the heating power of the air conditioner can be appropriately reduced, thereby reducing the overall vehicle power consumption and increasing the electric vehicle's range in cold conditions.

[0028] The embodiments of this application are described below with reference to the accompanying drawings. The terminology used in the implementation section of this application is for explaining specific embodiments only and is not intended to limit the scope of this application.

[0029] The embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art will recognize that, with technological advancements and the emergence of new scenarios, the technical solutions provided in the embodiments of this application are equally applicable to similar technical problems.

[0030] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, so that a process, method, system, product, or apparatus that comprises a series of elements is not necessarily limited to those elements, but may include other elements not explicitly listed or inherent to those processes, methods, products, or apparatuses.

[0031] Please see Figure 1 The diagram shows a schematic of an interior cabin of a car provided in an embodiment of this application.

[0032] like Figure 1 As shown, components in a car cabin that can be used to regulate the temperature inside the vehicle may include air conditioning and structures with heating components within the cabin.

[0033] For example, in this embodiment, the parts with heating components may include seats 101-106, steering wheel 107, center console 108, door trim panels 109-114, etc. Figure 1 The seats in the example may include a driver's seat 101, a front passenger seat 102, and rear seats 103-106. Each door panel corresponding to a seat may have a heating component, such as the door panel 109 on the left side of the driver's seat, the door panel 110 on the right side of the front passenger seat, and the door panels 111-114 on the sides of the middle and rear seats.

[0034] Understandable Figure 1 This illustration is for informational purposes only and does not constitute a specific limitation on the interior of a vehicle cabin. In other embodiments, the vehicle cabin may include more or fewer components than illustrated, or combine or separate certain components, or have different component arrangements.

[0035] As previously mentioned, current in-vehicle temperature control solutions involve independently controlling the cabin heating components and air conditioning unit to regulate the interior temperature. This independent control scheme increases the operational complexity for drivers and passengers. With the continuous development of smart cockpits, the number of heating components in the cabin is gradually increasing, further complicating user operations. Moreover, individually controlling each heating component increases the vehicle's energy consumption, especially for electric vehicles, reducing driving range in cold conditions.

[0036] To address the aforementioned technical problems, this application provides a method for controlling in-vehicle temperature. This method coordinates the control of the air conditioner's temperature and the heating element's temperature. The heating element locally heats the human body, while the air conditioner provides supplemental heat to untreated areas, allowing the in-vehicle temperature to quickly reach a comfortable range and improving user comfort. Furthermore, during the coordinated control process, activating the cabin heating element rapidly raises the local temperature of the human body, reducing the air conditioner's heating power and thus lowering overall vehicle energy consumption.

[0037] Please see Figure 2 The diagram illustrates a structural schematic of an in-vehicle temperature control system according to an embodiment of this application. Figure 2 As shown, the system includes an extended domain control unit (XCU) 201, an interior heating component controller, an air conditioning controller 206, an outside temperature sensor 207, an inside temperature sensor 208, a sunlight sensor 209, a heating component temperature sensor 210, and a seat occupancy sensor 211. The heating component controller may include a seat heating controller 202, a door panel heating controller 203, a steering wheel heating controller 204, and a center console heating controller 205.

[0038] In some embodiments of this application, the XCU may be a computing unit independent of the ECU.

[0039] Among them, the vehicle exterior temperature sensor 207 is used to collect the temperature signal of the external environment, and can further transmit the vehicle exterior temperature signal to the XCU.

[0040] The in-vehicle temperature sensor 208 is used to collect the in-vehicle ambient temperature signal, and can further transmit the collected in-vehicle temperature signal to the XCU.

[0041] The sunlight sensor 209 is used to collect information about sunlight shining on the car window glass, such as light intensity, and can further transmit the collected light information to the XCU.

[0042] XCU can calculate the energy demand value based on the ambient temperature inside the vehicle, the ambient temperature outside the vehicle, the light intensity, and the set temperature of the air conditioner. The energy demand value is positively correlated with the amount of heat required to reach a comfortable temperature inside the vehicle. That is, the higher the energy demand value, the lower the temperature inside the cabin and the colder the user feels.

[0043] The heating element temperature sensor 210 is used to acquire the temperature signal of the thermistor of the cabin interior heating element. For example, in this example, the thermistor can be a negative temperature coefficient thermistor (NTC). The temperature of the thermistor is the current temperature of the heating element.

[0044] The seat occupancy sensor 211 is used to detect whether someone is sitting in the seat, i.e., to obtain a seat occupancy signal. This occupancy signal can then be transmitted to the XCU 201. For example, each seat in the cabin has a seat occupancy sensor, and each sensor has a location number. This location number, along with the seat occupancy signal, can be transmitted to the XCU 201. In this way, the XCU 201 can determine which seat in the cabin is occupied based on the location number of the seat occupancy sensor.

[0045] The XCU201 collects vehicle operating environment information, namely the energy demand value (i.e., the in-vehicle TAU value) as X, the current temperature of the heating component as Y, and the seat occupancy signal as Z, and outputs the corresponding heating control command and air conditioning adjustment command for the heating component, and transmits them to the corresponding hardware controller.

[0046] In some embodiments, the XCU201 can determine which seats in the cabin are occupied based on the seat occupancy signal Z, and then activate the heating components corresponding to the occupied seats. For example, if the XCU receives two seat occupancy signals (Z value 2) located at the driver's seat and the front passenger seat, the door panel heating components, seat heating components, and passenger dashboard heating components corresponding to the driver's and front passenger seats, as well as the steering wheel heating component for the driver's seat, will be activated. Simultaneously, the front air conditioning vents will be activated, while the rear air conditioning vents will remain closed.

[0047] Furthermore, XCU201 transmits the seat heating control command to the seat heating controller 202, which responds to the command to control the heating components of the driver and passenger seats to heat them.

[0048] XCU201 transmits the door trim panel heating control command to the door trim panel heating controller 203. After receiving the command, the door trim panel heating controller 203 controls the heating components of the door trim panels corresponding to the driver and passenger seats to heat them.

[0049] XCU201 transmits the steering wheel heating control command to the steering wheel heating controller 204, and the steering wheel heating controller 204 responds to the command to control the steering wheel heating components to heat up.

[0050] XCU201 transmits the auxiliary instrument panel heating control command to the auxiliary instrument panel heating controller 205, and the auxiliary instrument panel heating controller 205 responds to the command to control the auxiliary instrument panel heating components to perform heating.

[0051] Additionally, XCU201 transmits the air conditioning adjustment command to the air conditioning controller 206, and the air conditioning controller 206 responds to the command to adjust the air outlet temperature and air volume of the air conditioner.

[0052] The following will combine Figure 3 This paper describes the implementation process of the in-vehicle temperature control method provided in the embodiments of this application. This method can be applied to... Figure 2 The XCU in the vehicle temperature control system shown is as follows: Figure 3 As shown, the method may include the following steps:

[0053] S101, Obtain vehicle operating environment information. This vehicle operating environment information includes information characterizing the internal and external environments of the vehicle.

[0054] In some embodiments, vehicle operating environment information includes relevant information characterizing the environment inside and outside the vehicle, such as the interior temperature, exterior temperature, sunlight intensity outside the vehicle, air conditioner set temperature (i.e., the aforementioned specified temperature), current temperature value of heating components, and seat occupancy signal.

[0055] The air conditioner's set temperature can be the user's desired interior temperature, that is, the interior temperature value that the user expects to achieve.

[0056] S102, determine the target heating element and its target temperature value based on vehicle operating environment information. The target temperature value is positively correlated with the initial amount of heat required to reach the specified temperature inside the vehicle.

[0057] S103, determine the target heating power of the air conditioner based on vehicle operating environment information. The target heating power is positively correlated with the first heat output, and the target heating power is less than the power required by the air conditioner to heat the interior environment to a specified temperature.

[0058] The target temperature of the heating element and the target heating power of the air conditioner are both positively correlated with the initial heat required to reach the specified temperature inside the vehicle. That is, the greater the initial heat, the greater the target temperature and the greater the target heating power; conversely, the smaller the initial heat, the smaller the target temperature and the smaller the target heating power. Moreover, the target heating power of the air conditioner is less than the power required by the air conditioner to heat the vehicle interior to reach the specified temperature.

[0059] S104 controls the temperature of the target heating element to reach the target temperature value, and controls the heating power of the air conditioner to reach the target heating power.

[0060] The temperature of the target heating element is controlled based on the determined target heating element and its corresponding target temperature value. At the same time, the heating power of the air conditioner is controlled based on the determined target heating power.

[0061] The in-vehicle temperature control method provided in this embodiment can achieve coordinated control of the air conditioner temperature and the temperature of the corresponding heating components. Specifically, it collects vehicle operating environment information, and further determines the target heating component and its corresponding target temperature value, as well as the target heating power of the air conditioner based on the collected vehicle operating environment information. Both the target temperature value of the heating component and the target heating power of the air conditioner are positively correlated with the first energy required to reach the specified in-vehicle ambient temperature. Finally, it controls the temperature of the target heating component based on its target temperature value, and simultaneously controls the heating power of the air conditioner based on the target heating power. In the coordinated control scenario, activating the heating component allows for heat conduction contact heating of the user's local area, thereby quickly raising the user's local temperature. Simultaneously, the air conditioner provides thermal supplementation to the overall in-vehicle environment. Since the heating component has been activated to quickly raise the user's local temperature, the heating power of the air conditioner can be appropriately reduced, thereby reducing the overall vehicle power consumption and increasing the electric vehicle's range in cold conditions.

[0062] The following is combined Figure 4 This application further elaborates on another method for controlling in-vehicle temperature provided in its embodiments, such as... Figure 4 As shown, the method may include:

[0063] S201, check if both the air conditioner switch and the microclimate switch are turned on; if so, proceed to S202, otherwise proceed to S207.

[0064] In some embodiments, after the vehicle is powered on (e.g., after the vehicle is unlocked and the start button is pressed), it can be detected whether the air conditioning and microclimate switches are turned on.

[0065] In some embodiments of this application, the vehicle's center console is equipped with an air conditioning switch and a climate control switch. These switches can be physical buttons / knobs or virtual buttons on the center console interface. The center console confirms that the climate control switch is activated after receiving a click from the user on the climate control switch button.

[0066] In some embodiments, the microclimate switch can be a switch in the air conditioning control interface. In this scenario, the microclimate switch can only be turned on after the air conditioning switch is turned on.

[0067] In other embodiments, the microclimate switch can be independent of the air conditioning switch. In this scenario, the microclimate switch can be a control switch for the vehicle's interior heating components. For example, when the microclimate switch is turned on independently, only the temperature of the corresponding interior heating component is adjusted.

[0068] An air conditioner switch controls the air conditioner to turn on and off. In addition, an air conditioner switch may include a fan speed control switch and a temperature control switch. After receiving a user's operation or electrical signal to trigger the air conditioner switch, the XCU determines that the air conditioner is on.

[0069] Furthermore, "microclimate switch" is only a schematic name and may be named by other names; this application does not limit this.

[0070] It is understood that S201 is an optional step. In scenarios where the vehicle is not equipped with a microclimate switch and / or air conditioning switch, the in-vehicle temperature control method provided in this application embodiment can be directly triggered after the vehicle is started in cold conditions, or the in-vehicle temperature control method can be triggered when the vehicle is detected to be running in a specified mode (such as the air conditioner heating mode). That is, S201 does not need to be executed, and S202 can be executed directly.

[0071] S202, Obtain vehicle operating environment information.

[0072] In some embodiments, vehicle operating environment information includes relevant information characterizing the environment inside and outside the vehicle, such as the interior temperature, exterior temperature, sunlight intensity, air conditioner set temperature, current temperature of heating components, and seat occupancy signal.

[0073] For example, an external ambient temperature sensor can be used to collect temperature information about the external environment of the vehicle. An internal ambient temperature sensor can be used to collect temperature information about the internal environment of the vehicle. A sunlight sensor can be used to collect information about the intensity of sunlight outside the vehicle. A heating element temperature sensor can be used to collect the current temperature of the thermistor in the heating element to obtain the current temperature of the heating element.

[0074] Seat occupancy signals can be obtained through seat occupancy sensors. As mentioned earlier, each seat in the cabin has a seat occupancy sensor, and each seat occupancy sensor has a location number. This location number, along with the seat occupancy signal, can be transmitted to the XCU. In this way, the XCU can determine which seat in the cabin is occupied based on the location number of the seat occupancy sensor.

[0075] In some embodiments of this application, the presence or absence of a seat can be determined by combining signals collected by a seat occupancy sensor and images captured by a camera, thus obtaining a seat occupancy signal. For example, images of each seat captured by a camera inside the vehicle can be used to further determine whether the image contains a human figure. For instance, if the seat occupancy sensor detects that someone is sitting in a seat, but the image captured by the camera does not contain a human figure, it is determined that the seat is unoccupied.

[0076] Each sensor can collect parameters of the vehicle's operating environment in real time or periodically; this application does not impose any special restrictions on this.

[0077] S203 determines the target heating component and its corresponding target temperature value, as well as the target heating power of the air conditioner, based on vehicle operating environment information.

[0078] In some embodiments, a seat in the cabin where someone is sitting can be determined based on a seat occupancy signal, thereby identifying the heating element corresponding to the seat where someone is sitting as the target heating element.

[0079] For example, the seat occupancy signal can be denoted as Z. If the Z value received by the XCU is 2, and the position information is the driver's seat and passenger seat, the target heating component is determined to include at least one of the following: the seat heating component corresponding to the driver's seat, the door panel heating component, the steering wheel heating component, and the passenger dashboard heating component, as well as the seat heating component and / or door panel heating component corresponding to the passenger seat.

[0080] Furthermore, the energy demand value (or in-vehicle TAU value) can be obtained based on vehicle operating environment information (such as indoor and outdoor ambient temperature, outdoor sunlight intensity, and air conditioner setting temperature). This energy demand value is positively correlated with the heat required to reach a specified temperature (such as the air conditioner setting temperature) in the vehicle interior. Further, the target temperature value of the target heating component is obtained based on the energy demand value and the current temperature of the target heating component.

[0081] In some embodiments, the target air outlet temperature and target air volume of the air conditioner can be obtained based on the energy demand value, and the target heating power of the air conditioner can be further determined based on the target air outlet temperature and target air volume.

[0082] In this embodiment, since the interior heating components in the cabin are already activated, they conduct heat to the user's local area, rapidly increasing the user's local temperature. Therefore, appropriately reducing the air conditioning heating power does not adversely affect the user's ability to reach a comfortable temperature in a short time. Thus, reducing the heating power of the air conditioner during the heating process, such as reducing the air conditioner's outlet temperature and / or air volume, can reduce the overall vehicle energy consumption to some extent.

[0083] In other words, in scenarios where the heating components and the air conditioner are controlled in tandem, the heating power corresponding to the set temperature of the same air conditioner is less than that in scenarios where the heating components and the air conditioner are controlled independently. Therefore, tandem control can reduce the overall vehicle energy consumption and increase the driving range in cold conditions.

[0084] S204, control the temperature of the target heating element to reach the target temperature value, and control the heating power of the air conditioner to reach the target heating power.

[0085] In some embodiments, the XCU can generate corresponding heating control commands based on the target heating component and the corresponding target temperature value determined in S203, and transmit them to the corresponding heating controller. The heating controller executes the heating control commands to heat the corresponding heating component. For example, a heating control command corresponding to the door trim panel, or door trim panel heating control command, is sent to the door trim panel heating controller to heat the door trim panel. A seat heating control command is sent to the seat heating controller to heat the seat. A steering wheel heating control command is sent to the steering wheel heating controller to heat the steering wheel. A passenger instrument panel heating control command is sent to the passenger instrument panel heating controller to heat the passenger instrument panel.

[0086] In some embodiments of this application, all door panel heating components in the cabin can share a single door panel heating controller; similarly, seat heating components in the cabin can also share a single seat heating controller.

[0087] The XCU sends the door panel heating control command to the door panel heating controller, which can parse the received heating control command to obtain the location information of the heating components that need to be turned on, as well as the target temperature of the heating components.

[0088] For example, the location information of the door panel heating element can be obtained by numbering the door panels within the cabin. For instance, the location number of the door panel heating element can be a numerical value; for example, "01" represents the door panel heating element corresponding to the driver's seat, i.e., Figure 1 The heating element corresponding to the middle door trim panel 109; "02" indicates the heating element of the door trim panel corresponding to the passenger side, i.e. Figure 1Heating components corresponding to the middle door trim panel 110; “03” indicates the heating component corresponding to the door trim panel 113 on the side of the middle row seat 104 behind the driver's seat; “04” indicates the heating component corresponding to the door trim panel 111 on the side of the middle row seat 103 behind the passenger seat; “05” indicates the heating component corresponding to the door trim panel 114 on the side of the rear seat 106; “06” indicates the heating component corresponding to the door trim panel 112 on the side of the rear seat 105.

[0089] The door panel heating controller parses the door panel heating control command to obtain the position information and target temperature of the door panel heating component, and controls the corresponding door panel heating component to gradually adjust to the corresponding target temperature.

[0090] Similarly, the seat heating controller parses the received seat heating control command to obtain the location information of the seat heating component to be turned on, as well as the target temperature, and turns on the corresponding seat heating component to heat up and gradually reach the corresponding target temperature.

[0091] After receiving the steering wheel heating control command, the steering wheel heating controller activates the steering wheel heating components to gradually heat the steering wheel to the target temperature.

[0092] In some embodiments, the secondary instrument panel also has a corresponding heating component and is equipped with a secondary instrument panel heating controller. After receiving a heating control command for the secondary instrument panel, the secondary instrument panel heating controller activates the heating component to gradually heat the instrument panel to reach the corresponding target temperature.

[0093] At the same time, the XCU can generate an air conditioning adjustment command based on the target air outlet temperature and target air volume of the air conditioner obtained from S204, and transmit it to the air conditioning controller. After receiving the air conditioning adjustment command, the air conditioning controller adjusts the air outlet temperature and air volume of the air conditioner so that the air outlet parameters of the air conditioner reach the corresponding target values, that is, controls the air outlet temperature to reach the target air outlet temperature and the air volume to reach the target air volume.

[0094] S205: Determine whether the monitoring duration has reached the preset duration; if yes, return to execute S202; otherwise, wait for a period of time before executing S205.

[0095] In the embodiments of this application, the process of controlling the heating component and the air conditioner can be based on a negative feedback closed-loop control process, where the negative feedback can be the latest obtained vehicle operating environment information. For example, the control parameters of the target heating component and the air conditioner can be adjusted at preset intervals based on the latest collected vehicle operating environment information.

[0096] In this embodiment, vehicle operating environment information, such as indoor and outdoor ambient temperature, outdoor sunlight intensity, air conditioner set temperature, NTC temperature of heating components, and seat occupancy signal, can be acquired at preset intervals (e.g., 1 second). Further, new heating control commands and air conditioning adjustment commands are generated based on the latest collected vehicle operating environment information and sent to the corresponding controllers. The controllers corresponding to each heating component and the air conditioning controller execute the latest control commands until the latest collected vehicle operating environment information meets the set information. If the indoor ambient temperature meets the user-set temperature, the air conditioner can switch to low-power operation to maintain the air conditioner set temperature inside the vehicle.

[0097] In one exemplary embodiment, the running time t can be recorded after the microclimate switch is turned on, and then the latest vehicle operating environment information can be obtained every preset time interval (e.g., 1 second).

[0098] Furthermore, obtaining the latest vehicle operating environment information at preset intervals can also monitor whether the set target has changed. For example, in one instance, after the air conditioner has been running for a period of time, if the user adjusts the air conditioner's set temperature, such as lowering it from 26°C to 24°C, the heating control command and air conditioning adjustment command corresponding to the heating component will be regenerated and sent to the corresponding controller.

[0099] For example, if the passenger in the front seat moves to the back seat midway through the journey, the detected seat occupancy signal will change, and the state of the heating components will be adjusted according to the latest seat occupancy signal. For example, the seat heating components and door panel heating components in the front passenger seat will be turned off, while the seat heating components and door panel heating components in the rear seats will be turned on.

[0100] S206: When the obtained TAU value inside the vehicle and / or the current temperature value of the heating components reach the preset value, the temperature adjustment of the comfort components in the cabin is completed.

[0101] In some embodiments of this application, when the collected vehicle operating environment information reaches the corresponding set value, it is determined that the corresponding heating component and / or air conditioner has reached the set working state, thus completing the temperature adjustment process of the comfort components in the cabin.

[0102] S207 allows for independent control of the temperature of the air conditioner or corresponding heating components.

[0103] In some embodiments, if the air conditioning switch and the microclimate switch are not detected to be on after the vehicle is powered on, the temperature of the component corresponding to the switch being turned on is controlled independently. For example, if only the air conditioning switch is on, the air outlet temperature and airflow of the air conditioner are adjusted separately. If only the microclimate switch is on, the temperature of the corresponding interior heating component is adjusted separately. The process of independently controlling the temperature of the air conditioning or interior heating component is the same as the existing control process and will not be described in detail here.

[0104] Furthermore, in scenarios where no air conditioning switch and / or microclimate switch are set, the air conditioner and other temperature-regulating components in the vehicle can be directly controlled by default, without an independent control mode.

[0105] S208, if the air conditioning switch and / or microclimate switch are detected to be off, the corresponding components are individually controlled to turn off.

[0106] For example, in one scenario, after the vehicle is powered on, the user turns on the air conditioning and climate control switches, and then turns off the climate control switch after a period of time. In this scenario, the XCU can detect that the climate control switch is off and send a shutdown command to the already activated heating controller, thus shutting down the corresponding heating components. Similarly, if the user turns off the air conditioning switch, the XCU will detect this and send a shutdown command to the air conditioning controller, thus turning off the air conditioning.

[0107] The in-vehicle temperature control method provided in this embodiment, upon detecting that both the air conditioning switch and the microclimate switch are turned on, coordinates the control of the air conditioner temperature and the temperature of the corresponding heating components. Specifically, it collects vehicle operating environment information, such as the ambient temperature inside and outside the vehicle, the intensity of sunlight outside the vehicle, the air conditioner's set temperature, the current temperature value of the heating components, and seat occupancy signals. Based on the collected vehicle operating environment information, it further determines the target heating component and its corresponding target temperature value, as well as the target heating power of the air conditioner. Finally, it controls the temperature of the target heating component based on its target temperature value, and simultaneously controls the airflow parameters of the air conditioner based on the target heating power. In this coordinated control scenario, since the internal heating components are already activated to conduct heat to the user's local area, the local temperature can be quickly increased, allowing for a suitable reduction in the air conditioner's heating power. This reduces the overall vehicle power consumption and increases the electric vehicle's range in cold conditions.

[0108] Please see Figure 5 The flowchart illustrates another in-vehicle temperature control method provided in an embodiment of this application, which is applied to... Figure 2 In the in-vehicle temperature control system shown, this embodiment... Figure 4 The steps in the illustrated embodiment are further refined. For example... Figure 5 As shown, the method may include the following steps:

[0109] S301, check if both the air conditioner switch and the microclimate switch are turned on; if so, proceed to S302; otherwise, proceed to S309.

[0110] S302, obtain vehicle operating environment information.

[0111] In this embodiment, S301 to S302 and Figure 4The implementation process of S201 to S202 is the same, and will not be repeated here.

[0112] S303 determines the target heating component that needs to be turned on based on the seat occupancy signal.

[0113] Based on the received seat occupancy signal, the target heating components to be activated are determined. Once the XCU analyzes the seat occupancy signal Z to obtain the position of the seat where someone is sitting, it can determine that the heating components related to the seat where someone is sitting are all target heating components. For example, assuming the seat occupancy signal Z value is 2 and the position is the driver's or passenger's seat, the target heating components in this example are the heating components related to the driver's seat, namely the driver's seat heating component, the door panel heating component on the left side of the driver's seat, the steering wheel heating component, and the passenger dashboard heating component. The heating components related to the passenger's seat are the passenger seat heating component and the door panel heating component on the right side of the passenger's seat.

[0114] S304: Based on the TAU value inside the vehicle and the current temperature value of the target heating component, query the first mapping relationship to obtain the target temperature corresponding to the heating component, generate a heating control command and send it to the corresponding heating controller.

[0115] In some embodiments, the in-vehicle TAU value can be calculated based on the in-vehicle ambient temperature, the outside ambient temperature, the intensity of sunlight outside the vehicle, and the air conditioner setting temperature.

[0116] In some embodiments of this application, a first mapping relationship is used to record the correspondence between different in-vehicle TAU values ​​and the current temperature value Y of the NTC of the heating component, and the target temperature corresponding to the NTC of the heating component. Based on the in-vehicle TAU value X and the current temperature value Y of the target heating component's NTC, the first mapping relationship is queried to obtain the target temperature value corresponding to the NTC of the target heating component. Further, a corresponding heating control command is generated based on the target temperature value of the target heating component's NTC. For example, if the target heating component is a steering wheel heating component, and the first mapping relationship shows that the target temperature of the heating component is 25°C, then a steering wheel heating control command is generated and sent to the steering wheel heating controller, thereby activating the steering wheel heating component to heat until it reaches 25°C.

[0117] Similarly, heating control commands for other heating components can be obtained and sent to the corresponding heating controllers, which will not be described in detail here.

[0118] The first mapping relationship in this embodiment is obtained based on a large amount of data from environmental simulation test chambers and test results from real environments.

[0119] S305: Based on the in-vehicle TAU value, query the second mapping relationship to obtain the air outlet temperature and air volume of the air conditioner, generate an air conditioning adjustment command based on the air outlet temperature and air volume, and send it to the air conditioning controller.

[0120] In some embodiments, the second mapping relationship is used to record the correspondence between the in-vehicle TAU value and the air outlet temperature and air volume of the air conditioner. The air outlet temperature and air volume of the air conditioner are obtained by querying the second mapping relationship based on the in-vehicle TAU value. Further, the heating power of the air conditioner is determined based on the air outlet temperature and air volume, and a corresponding air conditioning adjustment command is generated based on this heating power.

[0121] In the linkage control mode, the air outlet temperature and air volume of the air conditioner obtained based on the second mapping relationship are less than the air outlet temperature and air volume corresponding to the same set temperature. Therefore, the corresponding heating power value is determined to be less than the heating power corresponding to the set temperature of the air conditioner based on the air outlet temperature and air volume.

[0122] The first and second mapping relationships in this embodiment can be obtained based on a large amount of data from environmental simulation test chambers and test results from real environments.

[0123] S306, the heating component controller executes the heating control command to heat, and the air conditioning controller executes the air conditioning adjustment command to adjust the air outlet temperature and air volume of the air conditioner.

[0124] S307, XCU determines whether the in-vehicle monitoring time has reached the preset time; if so, it returns to execute S302; otherwise, it waits for a period of time before executing S307.

[0125] S308, when the obtained in-vehicle TAU value and / or the current temperature value of the heating components reach the preset value, the XCU determines that the temperature adjustment of the comfort components in the cabin has been completed.

[0126] S309 allows for independent control of the temperature of the air conditioner or its corresponding heating element.

[0127] The XCU can independently adjust the air conditioner's temperature or independently control the temperature of the interior heating components. It's understandable that when adjusting the air conditioner's temperature independently, the heating components operate at high power, allowing the air conditioner to reach the set temperature in a shorter time. In other words, in independent control mode, the heating power of the air conditioner at the same set temperature is greater than in the linked control mode.

[0128] S310: If the air conditioning switch and / or microclimate switch are detected to be off, the corresponding components will be turned off individually.

[0129] In this embodiment, S307~S310 and Figure 4 The implementation process of S205 to S209 in the illustrated embodiment is the same, and will not be repeated here.

[0130] The in-vehicle temperature control method provided in this embodiment, during the process of coordinating the control of the air conditioner temperature and the temperature of the corresponding heating components, can determine the target heating component that needs to be activated based on the seat occupancy signal. Furthermore, it obtains the target temperature corresponding to the target heating component by querying a first mapping relationship based on the in-vehicle TAU value and the NTC temperature value of the heating component; and obtains the air outlet temperature and airflow of the air conditioner by querying a second mapping relationship based on the in-vehicle TAU value. Further, it generates a corresponding heating control command based on the target temperature of the target heating component and sends it to the corresponding heating controller. Simultaneously, it generates a corresponding air conditioning adjustment command based on the air outlet temperature and airflow of the air conditioner and sends it to the air conditioning controller. Finally, the controller executes the commands to control the temperature of the corresponding components. In the coordinating control scenario, since the internal heating components are already activated to conduct heat to the user's local area through contact heating, the user's local temperature can be quickly increased, allowing for a suitable reduction in the heating power of the air conditioner, thereby reducing the overall vehicle power consumption and increasing the electric vehicle's range in cold conditions.

[0131] The above describes the in-vehicle temperature control method provided by the embodiments of this application. The following will describe the device embodiments corresponding to the above-described in-vehicle temperature control method.

[0132] Please see Figure 6 , Figure 6 This is a schematic diagram of a vehicle interior temperature control device provided in an embodiment of this application. The device is applied to… Figure 2 In the XCU shown, as Figure 6 As shown, the in-vehicle temperature control device includes:

[0133] The information acquisition module 201 is used to acquire vehicle operating environment information after detecting that the air conditioning switch and the microclimate switch are both turned on. The vehicle operating environment information includes energy demand value, current temperature value of heating components and seat occupancy signal.

[0134] In one possible implementation, the information acquisition module 201 is specifically used for:

[0135] The energy demand is calculated based on the ambient temperature inside the vehicle, the ambient temperature outside the vehicle, the intensity of sunlight outside the vehicle, and the set temperature of the air conditioner. The energy demand is positively correlated with the amount of heat required to reach the specified temperature inside the vehicle. The current temperature value of the thermistor inside the heating component is obtained through a temperature sensor. The seat occupancy signal is obtained based on the signal from the seat occupancy sensor.

[0136] In one possible implementation, when the information acquisition module 201 obtains the seat occupancy signal based on the signal from the seat occupancy sensor, it is specifically used to: acquire the signal collected by the seat occupancy sensor and the in-vehicle image captured by the in-vehicle camera; if the signal collected by the seat occupancy sensor indicates that someone is sitting in the first seat, determine whether the position corresponding to the first seat in the in-vehicle image contains a human image; if the position corresponding to the first seat does not contain a human image, determine that the first seat is unoccupied; if the position corresponding to the first seat contains a human image, determine that someone is sitting in the first seat.

[0138] In one possible implementation, the first determining module 202 is specifically used to: determine the target heating component based on the seat occupancy signal in the vehicle operating environment information; and determine the target temperature value of the target heating component based on the vehicle interior and exterior temperature information in the vehicle operating environment information.

[0139] In one possible implementation, when the first determining module 202 determines the target heating component based on the seat occupancy signal in the vehicle operating environment information, it is specifically used as follows: if the number of seat occupants is 1 and it is the driver's seat, the target heating component is determined to include a steering wheel heating component, a door panel heating component on the left side of the driver's seat, and / or a driver's seat heating component; if the number of seat occupants is greater than 1 and it is the driver's seat and other passenger seats, the target heating component is determined to include a steering wheel heating component, a door panel heating component on the left side of the driver's seat, and / or a driver's seat heating component, as well as door panel heating components and / or seat heating components corresponding to other passenger seats.

[0140] In one possible implementation, when the first determining module 202 determines the target temperature value of the target heating component based on the vehicle's internal and external temperature information in the vehicle's operating environment information, it is specifically used to: obtain the target temperature value of the target heating component based on the energy demand value and the current temperature of the target heating component.

[0141] The second determining module 203 is used to determine the target heating power of the air conditioner based on the vehicle operating environment information, wherein the target heating power is less than the power required to reach the set temperature of the air conditioner.

[0142] In one possible implementation, the second determining module 203 is specifically used to: obtain an energy demand value based on vehicle operating environment information, wherein the energy demand value is positively correlated with the heat required for the in-vehicle environment to reach a comfortable temperature; obtain the target air outlet temperature and target air volume of the air conditioner based on the energy demand value, wherein the target air outlet temperature is less than the set temperature of the air conditioner, and / or the target air volume is less than the set air volume of the air conditioner; and determine the target heating power of the air conditioner based on the target air outlet temperature and target air volume.

[0143] The first control module 204 is used to control the temperature of the target heating component to reach the target temperature value.

[0144] In some embodiments, the first control module 204 is specifically used to generate a corresponding heating control command based on the target heating component and the corresponding target temperature value determined by the first determining module, and send it to the heating controller corresponding to the target heating component. The heating controller executes the heating control command to control the temperature of the target heating component.

[0145] The second control module 205 is used to control the heating power of the air conditioner to reach the target heating power.

[0146] In some embodiments, the second control module 205 is specifically used to generate an air conditioning adjustment command based on the target heating power determined by the second determining module and send it to the air conditioning controller. The air conditioning controller executes the air conditioning adjustment command to control the air outlet temperature and air volume of the air conditioner.

[0147] The in-vehicle temperature control device provided in this embodiment can control the temperature of the air conditioner and the corresponding heating components in a coordinated manner. Specifically, the information acquisition module can collect vehicle operating environment information, such as the cabin temperature, the current temperature of the heating components, and seat occupancy signals, after detecting that both the air conditioner and microclimate switches are turned on. Further, the first determining module can determine the target heating component and its corresponding target temperature value based on the collected vehicle operating environment information, and the second determining module can determine the target heating power of the air conditioner based on the vehicle operating environment information. The first control module controls the temperature of the target heating component based on the target heating component and its corresponding target temperature value determined by the first determining module. The second control module controls the heating power of the air conditioner based on the target heating power determined by the second determining module, wherein the target heating power is less than the power required for the air conditioner to set its temperature. In the coordinated control scenario, since the internal heating components are already activated to conduct heat to the user's local area, the local temperature can be quickly increased. Therefore, the heating power of the air conditioner can be appropriately reduced, thereby reducing the overall vehicle power consumption and increasing the electric vehicle's range in cold conditions.
