Description

Technical Field

[0001] Embodiments of the present invention relate to vehicle control technology, and in particular, to a system and method for establishing a temperature buffer zone in a vehicle. Background Art

[0002] With the development of vehicle technology, vehicles are becoming more and more intelligent and automated to meet the growing needs of people, such as the needs for in-vehicle comfort and convenience.

[0003] Currently, the air conditioning system in a vehicle is often designed based on the in-vehicle space. That is, when the doors and windows are both closed, the air conditioning system blows the air that has been temperature-adjusted into the vehicle to achieve the cooling and heating functions in the vehicle.

[0004] However, when there is a large temperature difference between the inside and outside of the vehicle, when the door is opened, due to the effect of air convection, the outside air will enter the vehicle, resulting in a large fluctuation in the air temperature inside the vehicle, thereby reducing the comfort of the passengers inside the vehicle. Moreover, in order to improve the convenience of people getting on and off the vehicle, the opening area of the vehicle door is getting larger and larger, making the convective heat transfer between the inside and outside air of the vehicle larger when the door is opened, and thus the impact on the air temperature inside the vehicle is becoming more and more serious, resulting in worse comfort inside the vehicle. Summary of the Invention

[0005] Embodiments of the present invention provide a system and method for establishing a temperature buffer zone in a vehicle, which can effectively reduce the impact of door opening on the temperature inside the vehicle and improve the comfort inside the vehicle.

[0006] In a first aspect, embodiments of the present invention provide a system for establishing a temperature buffer zone in a vehicle, the system including: an air conditioning controller, a switching device, an air conditioner, and an air outlet device. Among them, the air conditioning controller is communicatively connected to the switching device, the switching device is disposed between the air conditioner and the air outlet device, and the air outlet device is disposed inside the door; where

[0007] the air conditioner adjusts the temperature of the air and outputs the temperature-adjusted air;

[0008] when the air conditioning controller detects that the vehicle meets the preset conditions for establishing a temperature buffer zone, it generates an air conduction instruction;

[0009] the switching device controls its switching state to the conducting state according to the air conduction instruction to transmit the temperature-adjusted air to the air outlet device;

[0010] the air outlet device blows the temperature-adjusted air towards the door opening area to establish a temperature buffer zone in the door opening area.

[0011] Second aspect, an embodiment of the present invention further provides a method for establishing a temperature buffer zone of a vehicle, including:

[0012] Adjust the temperature of the air via an air conditioner and output the temperature-adjusted air;

[0013] When the vehicle is detected to meet the preset temperature buffer zone establishment condition via an air conditioner controller, generate an air conduction instruction;

[0014] Control the switch state to the conducting state according to the air conduction instruction via a switch device, so as to transmit the temperature-adjusted air to an air outlet device;

[0015] Blow the temperature-adjusted air to the door opening area via the air outlet device, so as to establish a temperature buffer zone in the door opening area.

[0016] In the embodiment of the present invention, the air conditioner controller detects in real time whether the vehicle meets the preset temperature buffer zone establishment condition, and generates an air conduction instruction when it is detected that the preset temperature buffer zone establishment condition is met. The switch device controls the switch state to the conducting state according to the air conduction instruction, so as to transmit the temperature-adjusted air output by the air conditioner to the air outlet device arranged inside the door, so that the air outlet device can blow the temperature-adjusted air to the door opening area, and further establish a temperature buffer zone in the door opening area. Through the established temperature buffer zone, the interference of the outside temperature on the inside temperature caused by air convection can be reduced, thereby effectively reducing the influence of door opening on the inside temperature of the vehicle and improving the comfort inside the vehicle when the door is opened.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that, for the sake of description, only parts related to the present invention rather than all structures are shown in the drawings.

[0028] Figure 1 is a schematic structural diagram of a system for establishing a temperature buffer zone of a vehicle provided by an embodiment of the present invention. As Figure 1 shown, the temperature buffer zone establishing system includes an air-conditioning controller 10, a switching device 20, an air conditioner 30, and an air outlet device 40. Among them, the air-conditioning controller 10 is communicatively connected to the switching device 20. The switching device 20 is arranged between the air conditioner 30 and the air outlet device 40, and the air outlet device 40 is arranged inside the vehicle door.

[0029] Among them, the air conditioner 30 adjusts the temperature of the air and outputs the temperature-adjusted air. When the air-conditioning controller 10 detects that the vehicle meets the preset temperature buffer zone establishing condition, it generates an air conduction instruction. The switching device 20 controls the switching state to the conducting state according to the air conduction instruction, so as to transmit the temperature-adjusted air to the air outlet device 40. The air outlet device 40 blows the temperature-adjusted air to the vehicle door opening area, so as to establish a temperature buffer zone in the vehicle door opening area.

[0030] Among them, the air conditioner 30 can refer to the Heating, Ventilation and Air Conditioning (HVAC) device in a vehicle. The air conditioner 30 can also be communicatively connected to the air conditioner controller 10. The air conditioner 30 can adjust the air conditioner state according to the control instructions of the air conditioner controller 10. For example, it can adjust the air conditioner state to a cooling state or a heating state, and adjust the temperature of the air according to the temperature set by the user, and output the temperature-adjusted air into the vehicle to lower or raise the temperature in the vehicle. The air conditioner 30 and the air conditioner controller 10 can be set at any position in the vehicle based on service requirements, and the specific positions of the air conditioner 30 and the air conditioner controller 10 are not limited in this embodiment.

[0031] Among them, the temperature buffer zone can refer to a temperature buffer area established between the vehicle interior space and the vehicle exterior environment. For example, a temperature buffer zone is established within the door opening area. The preset temperature buffer zone establishment condition can refer to the condition that is preset based on service requirements and that the vehicle needs to meet when establishing a temperature buffer zone. Exemplarily, the preset temperature buffer zone establishment conditions include: the door opening angle is greater than or equal to a preset angle threshold, the difference between the vehicle interior temperature and the vehicle exterior temperature is greater than or equal to a preset temperature threshold, the vehicle's overall vehicle state is in the powered-on state and the air conditioner state of the air conditioner 30 is in the working state. The air conduction instruction can refer to an instruction to conduct the air between the air conditioner 30 and the air outlet device 40. Exemplarily, the air conduction instruction can be an instruction to control the switch device 20 to turn on the switch.

[0032] The air conditioner controller 10 can determine whether the vehicle meets the preset temperature buffer zone establishment condition at the current moment by real-time detecting the state information of the vehicle, and when it detects that the vehicle meets the preset temperature buffer zone establishment condition, it indicates that the current door is in the open state and a temperature buffer zone needs to be established for the door opening area. At this time, an air conduction instruction can be generated.

[0033] The switch device 20 can refer to a device that controls whether the air between the air conditioner 30 and the air outlet device 40 is conducted. The switch state of the switch device 20 includes a conducting state and a blocking state. The conducting state refers to the state in which the air output by the air conditioner 30 can be delivered to the air outlet device 40. The blocking state is the state in which the air output by the air conditioner 30 is prohibited from being delivered to the air outlet device 40. The air conditioner controller 10 can control the switch state of the switch device 20. When the switch device 20 receives the air conduction instruction, it can control its own switch state to the conducting state, so that the temperature-adjusted air output by the air conditioner 30 can be transmitted to the air outlet device 40.

[0034] The air outlet device 40 may refer to a device that blows the received air out through an outlet. For example, the air outlet device 40 may be, but is not limited to, an air outlet. The air outlet direction of the air outlet device 40 faces the door opening area so as to blow air to the door opening area. The air outlet device 40 may be provided on the inner side of each door of the vehicle so that a temperature buffer zone can be established within the opening area of each door. The door in this embodiment may refer to a door with a relatively large opening area, which may be, but is not limited to, a gull-wing door or a pair of opening doors. One or more air outlet devices 40 may be provided on the inner side of each door. The air outlet device 40 may be provided at any position on the inner side of the door, and its specific position may be determined based on the actual scenario. This embodiment does not make specific limitations on the number and installation position of the air outlet device 40. When the air outlet device 40 receives the temperature-adjusted air, it blows the temperature-adjusted air to the door opening area, thereby establishing a temperature buffer zone formed by the blown air within the door opening area to avoid direct contact between the air inside the vehicle and the air outside the vehicle, reduce air convection caused by excessive temperature difference, and further reduce the influence of the outside temperature on the inside temperature of the vehicle, so that the inside temperature of the vehicle remains unchanged when the door is opened, improving the comfort inside the vehicle.

[0035] The communication connection in this embodiment may be, but is not limited to, an electrical connection or a remote connection. Among them, the electrical connection may be a wired connection by means of a wire. The remote connection may refer to a wireless connection by means of a wireless network.

[0036] In the technical solution of this embodiment, the air conditioner controller 10 detects in real time whether the vehicle meets the preset temperature buffer zone establishment condition, and generates an air conduction instruction when it detects that the preset temperature buffer zone establishment condition is met. The switching device 20 controls the switch state to the on state according to the air conduction instruction, so as to transmit the temperature-adjusted air output by the air conditioner 30 to the air outlet device 40 provided on the inner side of the door, so that the air outlet device 40 can blow the temperature-adjusted air to the door opening area, and then establish a temperature buffer zone within the door opening area. Through the established temperature buffer zone, the interference of the outside temperature on the inside temperature of the vehicle caused by air convection can be reduced, thereby effectively reducing the influence of opening the door on the inside temperature of the vehicle and improving the comfort inside the vehicle when the door is opened.

[0037] On the basis of the above technical solution, the temperature buffer zone establishment system may further include a first connecting pipe 50. The two ends of the first connecting pipe are respectively connected to the air conditioner 30 and the air outlet device 40, and the temperature-adjusted air output by the air conditioner 30 is transmitted to the air outlet device 40 through the first connecting pipe 50. The first connecting pipe 50 can transmit the temperature-adjusted air output by the air conditioner 30 to the air outlet device 40. Correspondingly, as Figure 2As shown, the switch device 20 can be arranged between the air conditioner 30 and the first connecting pipe 50 to control whether the air output by the air conditioner 30 is transmitted into the first connecting pipe 50. In this embodiment, the switch device 20 can also be arranged between the first connecting pipe 50 and the air outlet device 40, or on the pipe of the first connecting pipe 50. The specific position of the switch device 20 is not limited in this embodiment.

[0038] Among them, the first connecting pipe 50 can refer to a pipe with a fixed shape to facilitate air transportation. The first connecting pipe 50 can be, but is not limited to, a plastic pipe. The pipe diameter of the first connecting pipe 50 can be directly equal to the outlet of the outlet device 40 to evenly blow more air through the outlet.

[0039] Based on the above technical solutions, Figure 3 a structural schematic diagram of a switch device is given. As Figure 3 shown, the switch device 20 includes: a switch unit 21, a connecting unit 22, and a motor 23. Among them, the switch unit 21 is connected to the motor 23 through the connecting unit 22, and the motor 23 is communicatively connected to the air conditioner controller 10. The motor 23 can, upon receiving an air conduction instruction, adjust the switch state of the switch unit 21 to the conduction state through the connecting unit 22. Exemplarily, as Figure 3 shown, the switch unit 21 can include, but is not limited to, a damper, and the damper rotates under the drive of the motor 23 to adjust the switch state. The connecting unit 23 can include, but is not limited to, a connecting rod, and the two ends of the connecting rod are respectively connected to the switch unit 21 and the motor 23, so that the motor 23 adjusts the switch state of the switch unit 21 through the connecting rod. For example, the motor 23 can rotate the connecting rod to make the damper rotate, so as to achieve the purpose of adjusting the switch state. For example, rotating the damper to the open state means the switch state is in the conduction state; rotating the damper to the closed state means the switch state is in the blocking state.

[0040] Based on the above technical solutions, as Figure 4As shown, the temperature buffer establishment system may further include: an in-vehicle temperature sensor 61 and an out-vehicle temperature sensor 62; wherein, the in-vehicle temperature sensor 61 detects the in-vehicle temperature of the vehicle and outputs the in-vehicle temperature; the out-vehicle temperature sensor 62 detects the out-vehicle temperature of the vehicle and outputs the out-vehicle temperature. The in-vehicle temperature sensor 61 may be disposed at any position in contact with the in-vehicle air to detect the in-vehicle air temperature. The out-vehicle temperature sensor 62 may be disposed at any position in contact with the out-vehicle air to detect the out-vehicle air temperature. In this embodiment, the in-vehicle temperature and the out-vehicle temperature can be monitored in real time through the in-vehicle temperature sensor 61 and the out-vehicle temperature sensor 62. Exemplarily, both the in-vehicle temperature sensor 61 and the out-vehicle temperature sensor 62 are communicatively connected to the air-conditioning controller 10 so that the air-conditioning controller 10 can obtain the in-vehicle temperature and the out-vehicle temperature.

[0041] Based on the above technical solutions, continue to refer to Figure 4 , the temperature buffer establishment system may further include: a body controller 70, and the body controller 70 generates an air-conditioning state detection instruction according to the vehicle's overall vehicle state and the received door opening angle. The body controller 70 is communicatively connected to the air-conditioning controller 10 so that the air-conditioning controller 10 can obtain the air-conditioning state detection instruction. Among them, the overall vehicle state may include a power-on state and a power-off state. The power-on state may refer to the state where the vehicle is started, and the power-off state may refer to the state where the vehicle is turned off. The air-conditioning state detection instruction refers to an instruction that can detect the air-conditioning state.

[0042] Continue to refer to Figure 4 , the temperature buffer establishment system may further include: a door opening angle detection circuit 80, and the door opening angle detection circuit 80 detects the door opening angle and outputs the door opening angle. The door opening angle detection circuit 80 may be any existing device that can detect the door opening angle, and it may be disposed on the door to detect the door opening angle in real time.

[0043] Specifically, the body controller 70 may include an overall vehicle state detection circuit, a door opening instruction generation circuit, and an air-conditioning state detection instruction generation circuit. Among them, the overall vehicle state detection circuit detects the overall vehicle state of the vehicle, generates a power-on instruction when the overall vehicle state is the power-on state, and outputs the power-on instruction; the door opening instruction generation circuit generates a door opening instruction and outputs the door opening instruction when the received door opening angle is greater than or equal to a preset angle threshold; the air-conditioning state detection instruction generation circuit generates an air-conditioning state detection instruction according to the power-on instruction and the door opening instruction, and outputs the air-conditioning state detection instruction.

[0044] Among them, the door opening instruction generation circuit is communicatively connected to the door opening angle detection circuit 80 so that the door opening instruction generation circuit can receive the detected door opening angle. Both the vehicle state detection circuit and the door opening instruction generation circuit are connected to the air-conditioning state detection instruction generation circuit so that the air-conditioning state detection instruction generation circuit can receive the power-on instruction and the door opening instruction.

[0045] The door opening instruction generation circuit may include a door opening angle input terminal, a comparator, and a door opening instruction output terminal. Among them, the detected door opening angle is input to the door opening angle input terminal. The comparator compares the door opening angle with a preset angle threshold value, and generates a door opening instruction when the door opening angle is greater than or equal to the preset angle threshold value. The door opening instruction output terminal outputs the door opening instruction. In this embodiment, by comparing the door opening angle at the current moment with the preset angle threshold value, the situation of establishing a temperature buffer zone when the door opening angle is small is avoided.

[0046] Specifically, the air-conditioning controller 10 may include an air-conditioning state detection circuit, an in-vehicle temperature acquisition port, an out-vehicle temperature acquisition port, and an air conduction instruction generation circuit. The air-conditioning state detection circuit is communicatively connected to the body controller 70 so that the air-conditioning state detection circuit receives the air-conditioning state detection instruction; the in-vehicle temperature acquisition port is communicatively connected to the in-vehicle temperature sensor; the out-vehicle temperature acquisition port is communicatively connected to the out-vehicle temperature sensor.

[0047] Among them, the air-conditioning state detection circuit detects the air-conditioning state of the air conditioner according to the received air-conditioning state detection instruction, and outputs a temperature acquisition instruction when the air-conditioning state is the working state. The in-vehicle temperature acquisition port acquires the in-vehicle temperature according to the temperature acquisition instruction. The out-vehicle temperature acquisition port acquires the out-vehicle temperature according to the temperature acquisition instruction. The air conduction instruction generation circuit generates an air conduction instruction according to the in-vehicle temperature and the out-vehicle temperature, and outputs the air conduction instruction. Among them, the air-conditioning state of the air conditioner 30 may include a working state and a closed state. The working state may include a refrigeration state and a heating state.

[0048] Exemplarily, the air conduction instruction generation circuit may include an in-vehicle temperature input terminal, an out-of-vehicle temperature input terminal, an arithmetic unit, a comparator, and an air conduction instruction output terminal. Among them, the in-vehicle temperature input terminal inputs the in-vehicle temperature; the out-of-vehicle temperature input terminal inputs the out-of-vehicle temperature; the arithmetic unit calculates the temperature difference between the in-vehicle temperature and the out-of-vehicle temperature; the comparator compares the temperature difference with a preset temperature threshold, and generates an air conduction instruction when the temperature difference is greater than or equal to the preset temperature threshold; the air conduction instruction output terminal outputs the air conduction instruction. When the air conduction instruction generation circuit detects that the temperature difference is greater than or equal to the preset temperature threshold, it indicates that the temperature inside and outside the vehicle is relatively large at the current moment, and it is necessary to establish a temperature buffer zone in the door opening area to avoid the interference of the out-of-vehicle temperature on the in-vehicle temperature. At this time, the air conduction instruction is generated and output.

[0049] Based on the above technical solutions, as Figure 5 shown, the temperature buffer zone establishment system may further include: a fog generation device 91, a liquid storage device 92, and a second connection pipe 93. Among them, the liquid storage device 93 is connected to the fog generation device 91 through the second connection pipe 92, the liquid storage device 93 is communicatively connected to the air conditioner controller 10, and the fog generation device 91 is disposed at a position preset length away from the air outlet device 40.

[0050] Among them, when the liquid storage device 93 receives a liquid delivery instruction, it delivers the stored liquid to the fog generation device 91 through the second connection pipe 92; the fog generation device 91 generates fog from the delivered liquid and sprays the fog toward the door opening area.

[0051] Among them, the fog generation device 91 refers to a device that can convert liquid into fog. Exemplarily, the fog generation device 91 may include, but is not limited to, at least one nozzle, and generates fog from the delivered liquid through the spray holes in the nozzle. The spraying direction of the fog generated by the fog generation device 91 is toward the door opening area, so as to spray fog toward the door opening area to achieve the effect of further cooling. The fog generation device 91 is also disposed inside the door, and the distance between it and the air outlet device 40 is a preset length. The size of the preset length can be preset based on the actual scenario. In this embodiment, the fog generation device 91 can be disposed near the air outlet device, so as to blow air and spray fog in the same door opening area to achieve the effect of further cooling.

[0052] Among them, the second connecting pipe 92 can be a pipe with a variable shape, which can be but is not limited to a rubber pipe for transporting liquid. The pipe diameter of the second connecting pipe 92 can be smaller than that of the first connecting pipe 50 to save space. The liquid storage device 93 refers to a device that can store liquid and control whether the liquid is transported. The liquid stored in the liquid storage device 93 can be pure water to generate clean mist. It should be noted that the liquid storage device 93 in this embodiment is different from the washing liquid storage device used for the vehicle's built-in windshield wiper. The liquid storage device 93 can include a liquid pump. The outlet of the liquid pump is connected to the second connecting pipe 92, and the liquid pump is communicatively connected to the air-conditioning controller 10. The liquid pump can receive a liquid transportation instruction and transport the stored liquid to the second connecting pipe 92 through the outlet. In this embodiment, the air-conditioning controller 10 can control the liquid pump to control whether the liquid storage device 93 transports the stored liquid to the second connecting pipe 92.

[0053] Exemplarily, the air-conditioning controller 10 can include: a liquid transportation instruction generation circuit; when the air-conditioning state of the air conditioner 30 is in a cooling state and the temperature difference between the in-vehicle temperature and the out-vehicle temperature is greater than or equal to a preset temperature threshold, the liquid transportation instruction generation circuit generates a liquid transportation instruction and outputs the liquid transportation instruction.

[0054] Among them, the liquid transportation instruction generation circuit can be connected to the air-conditioning state detection circuit, the in-vehicle temperature acquisition port, and the out-vehicle temperature acquisition port, so that the liquid transportation instruction generation circuit can obtain the air-conditioning state of the air conditioner 30, the in-vehicle temperature, and the out-vehicle temperature. Specifically, when the air-conditioning state detection circuit detects that the air-conditioning state of the air conditioner is the instruction state according to the received air-conditioning state detection instruction, it outputs a temperature acquisition instruction, so that the in-vehicle temperature acquisition port acquires the in-vehicle temperature and the out-vehicle temperature acquisition port acquires the out-vehicle temperature. The liquid transportation instruction generation circuit calculates the temperature difference according to the received in-vehicle temperature and out-vehicle temperature, and generates and outputs a liquid transportation instruction when the temperature difference is greater than or equal to the preset temperature threshold.

[0055] Specifically, when the liquid storage device 93 receives a liquid transportation instruction, it indicates that the current vehicle is in a cooling state, that is, the in-vehicle temperature is lower than the out-vehicle temperature. At this time, the stored liquid can be transported to the mist generation device 91, so that the mist generation device 91 sprays the generated mist to the door opening area. Based on the principle of heat absorption by mist evaporation, the cooling effect of the door opening area is enhanced, thereby improving the buffering effect of the temperature buffer area and further ensuring the comfort inside the vehicle.

[0056] Exemplarily, Figure 6 A side view of a vehicle is given; Figure 7 Given is Figure 6 The front view of the vehicle involved. As Figure 6 AndFigure 7 As shown, the vehicle door is a gull-wing door. If it is detected that the current vehicle meets the preset temperature buffer zone establishment condition, when the air conditioner 30 is in the heating state, that is, the air conditioner 30 outputs air with an increased temperature, making the temperature inside the vehicle higher than the temperature outside the vehicle, the air with an increased temperature can be transmitted through the first connecting pipe 50 to the air outlet device 40, and the air outlet device 40 blows the air with an increased temperature towards the door opening area, increasing the air temperature in the door opening area, thereby establishing a temperature buffer zone with a higher temperature. When the air conditioner 30 is in the cooling state, that is, the air conditioner 30 outputs air with a decreased temperature, making the temperature inside the vehicle lower than the temperature outside the vehicle, the air with a decreased temperature can be transmitted through the first connecting pipe 50 to the air outlet device 40, and the air outlet device 40 blows the air with a decreased temperature towards the door opening area, decreasing the air temperature in the door opening area. At the same time, the liquid stored in the liquid storage device 93 is transported through the second connecting pipe 92 to the fog generating device 91, and the fog generating device 91 generates fog from the transported liquid and sprays the fog towards the door opening area, thereby further decreasing the air temperature in the door opening area, strengthening the cooling effect, and further avoiding the influence of door opening on the temperature inside the vehicle. The established temperature buffer zone can be referred to the Figure 7 dashed area in

[0057] Based on the above technical solutions, the air conditioner controller 10 can also generate an air barrier instruction when it detects that the vehicle meets the preset temperature buffer zone cancellation condition; the switch device 20 controls the switch state to the barrier state according to the air barrier instruction to stop transmitting the temperature-adjusted air to the air outlet device.

[0058] Among them, the preset temperature buffer zone establishment condition can refer to the condition that is preset based on business requirements and that the vehicle needs to have when canceling the established temperature buffer zone. The preset temperature buffer zone cancellation condition can include at least one of: receiving a temperature buffer zone cancellation instruction, the air conditioner state of the air conditioner being in the off state, and the temperature difference between the temperature inside the vehicle and the temperature outside the vehicle being less than a preset temperature threshold. The air barrier instruction can refer to an instruction for blocking the air between the air conditioner 30 and the air outlet device 40. Exemplarily, the air conduction instruction can be an instruction for controlling the switch device 20 to close the switch.

[0059] Specifically, when the air conditioner state detection circuit in the air conditioner controller 10 detects that the air conditioner state of the air conditioner is in the off state, it indicates that the air conditioner does not output the air after temperature adjustment. At this time, an air barrier instruction can be directly generated; or, when the air barrier instruction generation circuit in the air conditioner controller 10 detects that the temperature difference between the vehicle interior temperature and the vehicle exterior temperature is less than the preset temperature threshold, it indicates that the temperatures inside and outside the vehicle are not much different and there is no need to establish a temperature buffer zone. At this time, an air barrier instruction can be generated; or, when the air barrier instruction generation circuit in the air conditioner controller 10 directly receives a temperature buffer cancellation instruction, it can directly generate an air barrier instruction. When the switching device 20 receives the air barrier instruction, it controls the switch state to the barrier state to stop transmitting the temperature-adjusted air to the air outlet device 40, so that the air temperature in the door opening area cannot be adjusted continuously, and thus the established temperature buffer zone can be cancelled.

[0060] Exemplarily, when the body controller 70 detects that the vehicle's overall vehicle state is in the power-off state or the door opening angle is less than the preset angle threshold, it generates a temperature buffer cancellation instruction. Specifically, the body controller 70 may include an overall vehicle state detection circuit, a door closing instruction generation circuit, and a temperature buffer cancellation instruction generation circuit. The overall vehicle state detection circuit can generate a power-off instruction and output the power-off instruction when it detects that the vehicle's overall vehicle state is in the power-off state; the door closing instruction generation circuit generates a door closing instruction and outputs the door closing instruction when the received door opening angle is less than the preset angle threshold; the temperature buffer cancellation instruction generation circuit generates a temperature buffer cancellation instruction and outputs the temperature buffer cancellation instruction when it receives the power-off instruction or the door closing instruction.

[0061] It should be noted that after establishing a temperature buffer zone by blowing the air with a reduced temperature to the door opening area through the air outlet device 40 and spraying the generated mist to the door opening area through the mist generating device 91, when the air conditioner controller 10 detects that the vehicle meets the preset temperature buffer cancellation condition, it generates an air barrier instruction and a liquid stop delivery instruction. The switching device 20 controls the switch state to the barrier state according to the air barrier instruction to stop transmitting the temperature-adjusted air to the air outlet device 40, so that the air outlet device 40 no longer blows air continuously. At the same time, the liquid storage device 93 stops delivering the stored liquid to the mist generating device according to the received liquid stop delivery instruction, so that the mist generating device 91 no longer sprays mist continuously, thereby cancelling the established temperature buffer zone.

[0062] The embodiment of the present invention also provides a method for establishing a temperature buffer zone of a vehicle. The method includes the following steps:

[0063] Adjust the temperature of the air through the air conditioner and output the temperature-adjusted air;

[0064] When the vehicle is detected by the air conditioner controller to meet the preset temperature buffer zone establishment condition, an air conduction instruction is generated;

[0065] Via the switching device, according to the air conduction instruction, the switch state is controlled to the conducting state, so as to transmit the temperature-adjusted air to the air outlet device;

[0066] Via the air outlet device, the temperature-adjusted air is blown to the door opening area, so as to establish a temperature buffer zone in the door opening area.

[0067] Specifically, the vehicle door can be, but is not limited to, a gull-wing door or a pair of opening doors. Exemplarily, the preset temperature buffer zone establishment condition can include: the door opening angle is greater than or equal to the preset angle threshold, the temperature difference between the in-vehicle temperature and the out-vehicle temperature is greater than or equal to the preset temperature threshold, the vehicle's overall vehicle state is in the powered-on state and the air conditioner state of the air conditioner is in the working state.

[0068] The technical solution of this embodiment, by generating an air conduction instruction when it is detected that the vehicle meets the preset temperature buffer zone establishment condition, controls the switch state to the conducting state according to the air conduction instruction, thereby transmitting the temperature-adjusted air output by the air conditioner to the air outlet device arranged inside the vehicle door, so that the air outlet device can blow the temperature-adjusted air to the door opening area, and then establish a temperature buffer zone in the door opening area. Through the established temperature buffer zone, the interference of the out-vehicle temperature on the in-vehicle temperature caused by air convection can be reduced, thereby effectively reducing the influence of door opening on the in-vehicle temperature and improving the comfort inside the vehicle when the door is opened.

[0069] Exemplarily, Figure 8 is a flowchart of a method for establishing a temperature buffer zone of a vehicle provided by an embodiment of the present invention. As Figure 8 shown, the method includes:

[0070] S110. The air conditioner adjusts the temperature of the air and outputs the temperature-adjusted air.

[0071] S120. When the air conditioner controller receives the air conditioner state detection instruction, it obtains the air conditioner state of the air conditioner.

[0072] Wherein, the air conditioner state can include a working state and a closed state. The working state can include a refrigeration state and a heating state.

[0073] Exemplarily, before receiving the air conditioner state detection instruction, the body controller generates an air conditioner state detection instruction according to the overall vehicle state of the vehicle and the received door opening angle. The air conditioner state detection instruction in this embodiment can be generated by the body controller.

[0074] Exemplarily, generating an air conditioner status detection instruction according to the overall vehicle status of the vehicle and the received door opening angle may include: detecting the overall vehicle status at the current moment of the vehicle; and generating an air conditioner status detection instruction when the overall vehicle status is the powered-on state and the received door opening angle is greater than or equal to a preset angle threshold.

[0075] S130. When the air conditioner status is the working state, obtain the in-vehicle temperature and the out-vehicle temperature of the vehicle via the air conditioner controller.

[0076] Specifically, when the air conditioner status is the working state, it indicates that the in-vehicle temperature is not equal to the out-vehicle temperature. At this time, the in-vehicle temperature of the vehicle can be obtained through the in-vehicle temperature sensor, and the out-vehicle temperature of the vehicle can be obtained through the out-vehicle temperature sensor.

[0077] S140. Via the air conditioner controller, determine the temperature difference according to the in-vehicle temperature and the out-vehicle temperature, and generate an air conduction instruction when the temperature difference is greater than or equal to a preset temperature threshold.

[0078] Specifically, if the working state of the air conditioner is the heating state, that is, the in-vehicle temperature is higher than the out-vehicle temperature, the difference between the in-vehicle temperature and the out-vehicle temperature can be used as the temperature difference. If the working state of the air conditioner is the cooling state, that is, the out-vehicle temperature is higher than the in-vehicle temperature, the difference between the out-vehicle temperature and the in-vehicle temperature can be used as the temperature difference. By comparing the temperature difference with the preset temperature threshold, when the temperature difference is greater than or equal to the preset temperature threshold, it indicates that the temperature difference between the inside and outside of the vehicle is large, and an obvious convective heat transfer effect will occur. At this time, an air conduction instruction is generated.

[0079] S150. Via the switching device, control the switch state to the conducting state according to the air conduction instruction to transmit the temperature-adjusted air to the air outlet device.

[0080] S160. Via the air outlet device, blow the temperature-adjusted air to the door opening area to establish a temperature buffer zone in the door opening area.

[0081] Exemplarily, Figure 9 is a flowchart of another method for establishing a temperature buffer zone of a vehicle provided by an embodiment of the present invention. As Figure 9 shown, the method includes:

[0082] S210. Adjust the temperature of the air via the air conditioner and output the temperature-adjusted air;

[0083] S220. When the air conditioner controller detects that the vehicle meets the preset temperature buffer zone establishment condition, generate an air conduction instruction;

[0084] S230. Control the switch state to the conducting state via the switching device according to the air conduction instruction, so as to transmit the temperature-adjusted air to the air outlet device;

[0085] S240. Blow the temperature-adjusted air to the door opening area via the air outlet device, so as to establish a temperature buffer zone in the door opening area.

[0086] S250. When the vehicle is detected to meet the preset temperature buffer zone cancellation condition via the air conditioner controller, generate an air barrier instruction.

[0087] Wherein, the preset temperature buffer zone cancellation condition may include at least one of: receiving a temperature buffer zone cancellation instruction, the air conditioner state of the air conditioner being the off state, and the difference between the vehicle interior temperature and the vehicle exterior temperature being less than a preset temperature threshold.

[0088] Exemplarily, before receiving the temperature buffer zone cancellation instruction, when the vehicle body controller detects that the overall vehicle state of the vehicle is the power-off state or the door opening angle is less than a preset angle threshold, generate a temperature buffer zone cancellation instruction. The temperature buffer zone cancellation instruction in this embodiment may be generated by the vehicle body controller.

[0089] S260. When receiving the air barrier instruction via the switching device, control the switch state to the barrier state, so as to stop transmitting the temperature-adjusted air to the air outlet device.

[0090] Specifically, when receiving the air barrier instruction, the switching device controls the switch state to the barrier state, so as to stop transmitting the temperature-adjusted air to the air outlet device, thereby unable to continue adjusting the air temperature in the door opening area, and further canceling the established temperature buffer zone.

[0091] Exemplarily, the method may further include: when receiving a liquid delivery instruction via the liquid storage device, deliver the liquid stored in the liquid storage device to the fog generation device; generate fog from the delivered liquid via the fog generation device and spray the fog to the door opening area.

[0092] Wherein, before receiving the liquid delivery instruction, it may further include: when the air conditioner controller detects that the air conditioner state of the air conditioner is the refrigeration state and the temperature difference between the vehicle interior temperature and the vehicle exterior temperature is greater than or equal to a preset temperature threshold, generate a liquid delivery instruction.

[0093] Exemplarily, Figure 10 is a flowchart of another method for establishing a temperature buffer zone of a vehicle provided by an embodiment of the present invention. As Figure 10 shown, the method includes:

[0095] S311. Detect whether the door opening angle is greater than or equal to the preset angle threshold via the body controller. If so, enter S312; if not, enter S318.

[0096] It should be noted that this embodiment does not limit the sequence of S310 and S311, that is, the sequence of detecting the overall vehicle status and the door opening angle. For example, the overall vehicle status can be detected first and then the door opening angle, or the door opening angle can be detected first and then the overall vehicle status.

[0097] S312. Obtain the air-conditioning status of the air conditioner via the air-conditioning controller. If the air-conditioning status is the heating state, enter S313; if the air-conditioning status is the cooling state, enter S314; if the air-conditioning status is the off state, enter S318.

[0098] S313. Determine the difference between the in-vehicle temperature and the out-vehicle temperature as the first temperature difference, and detect whether the first temperature difference is greater than or equal to the preset temperature threshold. If so, enter S315; if not, enter S318.

[0101] S316. Control the switch state to the conducting state via the switch device, so as to transmit the air with decreased temperature to the air outlet device, and blow the air with decreased temperature to the door opening area via the air outlet device, so as to establish a temperature buffer zone in the door opening area, and enter S317.

[0102] S317. Transport the stored liquid to the fog generating device via the liquid storage device, generate fog from the transported liquid via the fog generating device, spray the fog to the door opening area, and return to execute S310.

[0103] It should be noted that this embodiment does not limit the execution sequence of S316 and S317. For example, S316 can be executed first and then S317, or S317 can be executed first and then S316, or S316 and S317 can be executed simultaneously.

[0104] S318. When it is detected via the switch device that the switch state is in the conducting state, control the switch state to the blocking state to stop transmitting the temperature-adjusted air to the air outlet device, and when it is detected via the liquid storage device that the liquid is in the conveying state, stop conveying the stored liquid to the mist generating device.

[0105] It should be noted that the above process only gives the process of establishing a temperature buffer once and canceling the established temperature buffer. The above process can be cycled, that is, continuously establish a temperature buffer and cancel the established temperature buffer.
