[0033] Please refer to Figure 1 , Figure 1 is a frame schematic diagram of an embodiment of the vehicle cooling system provided by the present application. As Figure 1 shown, the system comprises a thermal imaging detection unit 10, a control unit 20 and a cooling module 30.

[0034] The thermal imaging detection unit 10 is used to detect a first thermal imaging image of the vehicle interior and send the first thermal imaging image to the control unit 20. The thermal imaging detection unit 10 is located on the roof of the vehicle interior. The specific installation position of the thermal imaging detection unit 10 on the roof can be determined according to actual needs, and the present embodiment does not make specific limitation thereon. For example, the thermal imaging detection unit 10 can be located on the roof corresponding to the front cockpit area, at this time, the first thermal imaging image can be a thermal imaging image corresponding to the front cockpit area.

[0035] The control unit 20 is used to acquire the first thermal imaging image detected by the thermal imaging detection unit 10, determine a first high temperature area in the first thermal imaging image, and control the cooling module 30 to cool a second high temperature area corresponding to the first high temperature area in the vehicle interior. Wherein, the first high temperature area is a region in the first thermal imaging image with a temperature greater than a first temperature threshold. The second high temperature area is an actual high temperature area corresponding to the first high temperature area in the vehicle interior.

[0036] Since the first thermal imaging image detected by the thermal imaging detection unit 10 is a temperature distribution map, the control unit 20 can directly determine the first high-temperature area in the local part of the first thermal imaging image, and then control the cooling module 30 to cool the second high-temperature area in the local part of the vehicle interior corresponding to the first high-temperature area.

[0037] Please refer to Figure 2 , Figure 2 is a frame schematic diagram of another embodiment of the vehicle cooling system provided by the present application. As shown in Figure 2 , the system includes a thermal imaging detection unit 10, a control unit 20 and a cooling module 30. The control unit 20 includes a first controller 21, a second controller 22 and a third controller 23, and the cooling module 30 includes a rotary driving device 31 and a liquid nitrogen spraying device 32.

[0038] Among them, the thermal imaging detection unit 10 is electrically connected with the first controller 21. Exemplarily, the thermal imaging detection unit 10 can be an infrared thermal imager or other thermal imaging device.

[0039] The first controller 21 is in communication connection with the second controller 22, for example, the first controller 21 is connected with the second controller 22 through vehicle-mounted Ethernet. The second controller 22 is in communication connection with the third controller 23, for example, the second controller 22 is connected with the third controller 23 through CAN (Controller Area Network). Exemplarily, the first controller 21 and the second controller 22 are both intelligent cockpit domain SOC. The third controller 23 is electrically connected with the cooling module 30. Exemplarily, the third controller 23 is MCU (Microcontroller Unit). It should be noted that in the present embodiment, the first controller 21, the second controller 22 and the third controller 23 are exemplarily illustrated as being included in the control unit 20. In other embodiments, the first controller 21, the second controller 22 and the third controller 23 can be the same controller, or the first controller 21 and the second controller 22 can be the same controller, or the second controller 22 and the third controller 23 can be the same controller, which is not limited in the present embodiment.

[0040] The cooling module 30 is located on the roof of the vehicle interior, for example, the cooling module 30 is located on the roof corresponding to the front driver's cabin area. The cooling module 30 includes a rotary drive device 31 and a liquid nitrogen injection device 32, the rotary drive device 31 is used to drive the liquid nitrogen injection device 32 to rotate. In an example, the rotary drive device 31 includes a motor drive and a stepper motor, the drive signal input end of the motor drive is electrically connected with the drive signal output end of the third controller 23, and the drive signal output end of the motor drive is connected with the drive signal input end of the stepper motor. The liquid nitrogen injection device 32 includes a nozzle, which can be connected with a liquid nitrogen storage device through a pipeline. The liquid nitrogen storage device stores liquid nitrogen and can be located in the trunk of the vehicle. The pipeline is provided with an electronic valve, and the signal input end of the electronic valve is electrically connected with the control signal output end of the third controller 23. The shaft of the stepper motor can be connected with a support rod through a connecting piece, and the support rod is perpendicular to the shaft of the stepper motor. The nozzle can be arranged at one end of the support rod away from the stepper motor, and the opening of the nozzle faces downward.

[0041] In a specific application, the thermal imaging detection unit 10 is used to detect a first thermal image of the vehicle interior and send the first thermal image to the first controller 21. The first controller 21 receives the first thermal image and sends the first thermal image to the second controller 22. The second controller 22 receives the first thermal image and sends the first thermal image to the third controller 23. The third controller 23 receives the first thermal image and determines a first high temperature area in the first thermal image, determines a target rotation angle of the rotary drive device 31 based on the first high temperature area, controls the rotary drive device 31 to rotate the target rotation angle, so that the liquid nitrogen injection device is aligned with a second high temperature area, and controls the liquid nitrogen injection device 32 to spray liquid nitrogen on the second high temperature area.

[0042] The drive signal output by the third controller 23 drives the stepper motor to rotate the target rotation angle, which drives the nozzle to rotate to the upper side of the second high temperature area corresponding to the first high temperature area in the vehicle interior. Then, the third controller 23 outputs a control signal to the electronic valve on the pipeline to control the electronic valve to open, so that the liquid nitrogen stored in the liquid nitrogen storage device can flow to the nozzle through the pipeline, and the nozzle can spray liquid nitrogen on the second high temperature area. Since the liquid nitrogen absorbs heat during vaporization, spraying liquid nitrogen on the second high temperature area can achieve the purpose of cooling the second high temperature area.

[0043] Optionally, in the embodiment, the cooling module 30 includes a rotating driving device 31 and a liquid nitrogen spraying device 32. In other embodiments, the cooling module 30 can include a displacement device and a liquid nitrogen spraying device. The displacement device and the liquid nitrogen spraying device are fixedly connected, and the displacement device is electrically connected with the third controller 23. The displacement device can move the liquid nitrogen spraying device to any position in the front cabin area. For example, after determining the first high-temperature area in the first thermal image, the third controller 23 can output a control signal to the displacement device to control the displacement device to move the liquid nitrogen spraying device to a second high-temperature area corresponding to the first high-temperature area in the vehicle interior, and control the liquid nitrogen spraying device to cool the second high-temperature area.

[0044] Optionally, in the embodiment, the cooling system can further include a first electronic compass 41 and a second electronic compass 42. In an implementation, the first electronic compass 41 is integrated in the vehicle interior, and the pointing direction of the first electronic compass is synchronized with the orientation of the vehicle head. For example, the first electronic compass 41 is electrically connected with the first controller 21, and the first electronic compass 41 is configured to send the detected azimuth angle to the first controller 21. The second electronic compass 42 is integrated on the liquid nitrogen spraying device 32, and the pointing direction of the second electronic compass 42 can be the same as or different from the orientation of the liquid nitrogen spraying device 32. For example, the second electronic compass 42 is electrically connected with the third controller 23, and the second electronic compass 42 is configured to send the detected azimuth angle to the third controller 23. In the embodiment, the first electronic compass 41 and the second electronic compass 42 can be the same electronic compass or different electronic compasses. The third controller 23 is configured to determine a first azimuth angle of the second high-temperature area based on the azimuth angle detected by the first electronic compass 41, determine a second azimuth angle of the liquid nitrogen spraying device 32 based on the azimuth angle detected by the second electronic compass 42, and take the angle difference between the first azimuth angle and the second azimuth angle as the target rotation angle of the rotating driving device 31.

[0045] Optionally, in the embodiment, the cooling system can further include a BCM (Body Control Module) 51 and an air conditioner 52. The BCM 51 is electrically connected with the second controller 22, and the BCM 51 is electrically connected with the air conditioner 52.

[0047] Referring to Figure 3 , Figure 3 is a flowchart of an embodiment of the vehicle cooling method provided by the present application. The method can be applied to the vehicle cooling system shown in Figure 1 or Figure 2 , and can be executed by the control unit described above. It should be noted that the method of the present application is not limited to the order of the steps shown in Figure 3 . As shown in Figure 3 , the method includes the following steps:

[0048] S31: Obtain a first thermal image of the interior of the vehicle.

[0049] Specifically, the first thermal image detected by the thermal imaging detection unit described above can be obtained. For details, please refer to the embodiments shown in Figure 1 and Figure 2 , which will not be described here.

[0050] S32: Determine a first high-temperature area in the first thermal image.

[0051] The first high-temperature area is an area in the first thermal image with a temperature greater than a first temperature threshold. The second high-temperature area is an actual high-temperature area in the interior of the vehicle corresponding to the first high-temperature area. The first temperature threshold can be set according to actual needs.

[0052] S33: Control the cooling module to cool a second high-temperature area in the interior of the vehicle corresponding to the first high-temperature area.

[0053] In an embodiment, the cooling module includes the rotary drive device and the liquid nitrogen spraying device described above. Then, step S33 includes: determining a target rotation angle of the rotary drive device, controlling the rotary drive device to rotate the target rotation angle so that the liquid nitrogen spraying device is aligned with the second high-temperature area, and controlling the liquid nitrogen spraying device to spray liquid nitrogen on the second high-temperature area to cool the second high-temperature area in the interior of the vehicle.

[0054] In another embodiment, the cooling module includes the aforementioned displacement device and the liquid nitrogen spraying device. Step S33 includes: controlling the displacement device to move the liquid nitrogen spraying device above the second high-temperature area, and controlling the liquid nitrogen spraying device to spray liquid nitrogen on the second high-temperature area to cool the second high-temperature area in the vehicle interior.

[0055] In this embodiment, a first thermal image of the vehicle interior is acquired, and a first high-temperature area in the first thermal image is determined, the first high-temperature area being an area in the first thermal image with a temperature greater than a first temperature threshold. Then, the cooling module is controlled to cool a second high-temperature area in the vehicle interior corresponding to the first high-temperature area. In this way, the local high-temperature area in the vehicle interior can be cooled, and the cooling effect of the vehicle is improved.

[0056] Referring to Figure 4 , Figure 4 is a flowchart of another embodiment of the vehicle cooling method provided by the present application. The method can be applied to the vehicle cooling system shown in Figure 2 . For example, the method can be executed by the third controller in Figure 2 . As shown in Figure 4 , the method includes the following steps:

[0057] S41: Acquire a first thermal image of the vehicle interior.

[0058] S42: Determine a first high-temperature area in the first thermal image.

[0059] S43: Determine a target rotation angle of the rotary drive device based on the first high-temperature area.

[0060] In an embodiment, the first thermal image can be divided into a plurality of sub-areas first, and then a first sub-area in which the first high-temperature area is located and a second sub-area in which the projection of the liquid nitrogen spraying device is located are determined, and then the target rotation angle of the rotary drive device is determined based on the first sub-area and the second sub-area.

[0061] Referring to Figure 5 , Figure 5 is a flowchart of an embodiment of the method for determining the target rotation angle provided by the present application. As shown in Figure 5 , the method includes the following steps:

[0062] S501: Divide the first thermal image into a plurality of sub-areas according to a preset division angle with the image center point of the first thermal image as a reference point.

[0063] The preset division angle can be set according to actual needs, and the embodiment is not limited specifically. For example, the preset division angle is 10°, and the first thermal imaging image is divided into 36 sub-regions. For another example, the preset division angle is 45°, and the first thermal imaging image is divided into 8 sub-regions.

[0064] S502: determining a first sub-region in which the first high-temperature region in the first thermal imaging image is located, and a second sub-region in which the projection of the liquid nitrogen spraying device in the first thermal imaging image is located.

[0065] The first sub-region and the second sub-region are each one of a plurality of sub-regions.

[0066] In an example, the first sub-region in which the first high-temperature region is located can be determined directly based on the distribution of the first high-temperature region in the first thermal imaging image.

[0067] In an example, the control unit stores a historical sub-region in which the projection of the liquid nitrogen spraying device is located. The historical sub-region is a sub-region in which the liquid nitrogen spraying device projects when the liquid nitrogen spraying device sprays liquid nitrogen last time. Therefore, the historical sub-region can be used as the second sub-region. Alternatively, each time the liquid nitrogen spraying device finishes spraying liquid nitrogen, the control unit controls the rotary driving device to drive the liquid nitrogen spraying device to rotate to a fixed position. When the liquid nitrogen spraying device is located at the fixed position, the sub-region in which the projection of the liquid nitrogen spraying device in the first thermal imaging image is located is a preset sub-region. The control unit stores the preset sub-region. Therefore, the preset sub-region can be used as the second sub-region.

[0068] S503: determining a target rotation angle based on the first sub-region and the second sub-region.

[0069] In an example, the plurality of sub-regions are respectively provided with corresponding digital numbers, and the digital numbers corresponding to different sub-regions are different. Step S503 can include: determining an absolute value of a difference between the digital number of the second sub-region and the digital number of the first sub-region; and determining the target rotation angle based on the preset division angle, the absolute value of the difference between the digital number of the second sub-region and the digital number of the first sub-region. Specifically, the preset division angle is multiplied by the absolute value of the difference between the digital number of the second sub-region and the digital number of the first sub-region to obtain the target rotation angle. For example, the preset division angle is 30°, the digital number of the second sub-region is 4, and the digital number of the first sub-region is 1. Then, the target rotation angle is 90°.

[0070] In another embodiment, in order to further improve the accuracy of the determined target rotation angle, a first azimuth angle of the second high-temperature region and a second azimuth angle of the liquid nitrogen spraying device are determined first, and then the target rotation angle of the rotation driving device is determined based on the first azimuth angle and the second azimuth angle. In this embodiment, the range of the azimuth angle can be 0°-360°, wherein 0° or 360°, 90°, 180°, and 270° correspond to north, east, south, and west respectively.

[0071] Please refer to Figure 6 , Figure 6 is a flowchart of another embodiment of the method for determining the target rotation angle provided by the present application. As shown in Figure 6 , the method comprises the following steps:

[0072] S601: Determine the first azimuth angle of the second high-temperature region.

[0073] In an embodiment, step S601 can comprise the following sub-steps:

[0074] Sub-step one, obtain the third azimuth angle of the vehicle detected by the first electronic compass.

[0075] The related content of the first electronic compass can refer to the embodiment shown in Figure 2 , and the detailed description is omitted here.

[0076] Sub-step two, fuse the preset electronic compass scale into the first thermal imaging image to obtain a second thermal imaging image.

[0077] The difference between the second thermal imaging image and the first thermal imaging image is that the second thermal imaging image further includes a preset electronic compass scale. The preset electronic compass scale can be several compass scales of any electronic compass stored in advance.

[0078] Sub-step three, determine the fourth azimuth angle of the first high-temperature region in the second thermal imaging image.

[0079] Since the second thermal imaging image includes the preset electronic compass scale, the fourth azimuth angle corresponding to the first high-temperature region under the preset electronic compass scale can be directly determined from the second thermal imaging image.

[0080] Sub-step four, perform first correction on the fourth azimuth angle by using the third azimuth angle.

[0081] Since the fourth azimuth angle is the azimuth angle of the first high-temperature region in the second thermal imaging image, and is not the actual azimuth angle of the second high-temperature region inside the vehicle, the fourth azimuth angle needs to be corrected. Specifically, the process of the first correction includes: determining the azimuth angle sum between the third azimuth angle and the fourth azimuth angle; if the azimuth angle sum is greater than 360°, the azimuth angle after the azimuth angle sum is subtracted by 360° is taken as the fourth azimuth angle after the first correction; if the azimuth angle sum is less than 360°, the azimuth angle sum is taken as the fourth azimuth angle after the first correction.

[0082] For example, the fourth azimuth angle of the first high-temperature region in the second thermal imaging image is 15°, and the third azimuth angle detected by the first electronic compass is 90°, and then 105° is the fourth azimuth angle after the first correction. For another example, the fourth azimuth angle of the first high-temperature region in the second thermal imaging image is 60°, and the third azimuth angle detected by the first electronic compass is 330°, and then 30° is the fourth azimuth angle after the first correction.

[0083] Sub-step five, the fourth azimuth angle after the first correction is selected as the first azimuth angle.

[0084] The fourth azimuth angle after the first correction is the actual azimuth angle of the second high-temperature region.

[0085] Alternatively, the above sub-steps one to five can also be replaced by: acquiring the third azimuth angle of the vehicle detected by the first electronic compass; performing third correction on the preset electronic compass scale by using the third azimuth angle to obtain the preset electronic compass scale after the third correction; fusing the preset electronic compass scale after the third correction into the first thermal imaging image to obtain a third thermal imaging image; determining the fifth azimuth angle of the first high-temperature region in the third thermal imaging image; and taking the fifth azimuth angle as the first azimuth angle.

[0086] Specifically, the process of the third correction includes: for each compass scale of the preset electronic compass scale, determining the azimuth angle difference between the third azimuth angle and each compass scale; if the azimuth angle difference is less than 0, the azimuth angle after the azimuth angle difference is added by 360° is taken as the compass scale after the third correction; if the azimuth angle difference is greater than 0, the azimuth angle difference is taken as the compass scale after the third correction.

[0087] S602: Determine the second azimuth angle of the liquid nitrogen spraying device.

[0088] In an embodiment, the pointing azimuth of the second electronic compass is the same as the orientation of the liquid nitrogen spraying device, and the azimuth angle detected by the second electronic compass can be directly taken as the second azimuth angle.

[0089] In another embodiment, the pointing direction of the second electronic compass is different from the orientation of the liquid nitrogen spraying device, a third correction is performed on the azimuth angle detected by the second electronic compass, and the third corrected azimuth angle is taken as the second azimuth angle.

[0090] Specifically, the third correction includes subtracting a preset azimuth angle difference from the azimuth angle detected by the second electronic compass to obtain the third corrected azimuth angle. The preset azimuth angle difference is determined according to the actual placement position of the second electronic compass and the liquid nitrogen spraying device.

[0091] S603: Obtain the angle difference between the first azimuth angle and the second azimuth angle as the target rotation angle.
