[0075] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0076] According to a first aspect of the present application, a control system 100 is provided for controlling the operation of vehicle windows, including: an inter-window detector 110 and a controller 120 .

[0077] Among them, the window detector 110 is at least used to detect the temperature of the window area 17 of the vehicle. The controller 120 is used to control the movement of the window according to the detection result of the window detector 110. The window area 17 mentioned in the present application is, for example, an area where the window can be moved on the vehicle, that is, a space for the window to move formed by the frame of the door. It can be understood that for some vehicles, the frame is not completely closed, that is, the door only has a part of the door frame to surround the window, and another part of the frame surrounding the window is formed on the body of the vehicle. At this time, the window area 17 can also refer to the space area for the window to move surrounded by the door and the body frame when the door is closed. When the user is using the vehicle, if the user's limbs are in the window area 17, when the window is closed, as the window moves, the user's limbs may be pinched by the window and the frame on the vehicle located outside the window.

[0078] The present application adopts a method of detecting the temperature of the area 17 between the windows. When the window moves, for example, when the window is closed, the temperature of the area 17 between the windows is detected by the window detector 110. When there is a user's limb in the area 17 between the windows and there is a risk of the user being pinched, the controller 120 controls the window to prevent the window from continuing to close. Compared with conventional solutions such as when there are debris in the area 17 between the windows that causes the window to close, and after the window pinches the user's limb or debris and exerts a force on the window, the mechanical sensing method is used to prevent the window from continuing to close, the control system 100 provided by the present application can more directly detect whether there is a user's limb in the area 17 between the windows during the window closing process by detecting the temperature of the area 17 between the windows, thereby reducing the possibility of the user's limb being pinched and improving safety performance.

[0079] In some embodiments, the controller 120 receives the electrical signal containing the temperature information of the window area 17 sent by the window detector 110, and controls the movement of the vehicle window according to the electrical signal containing the temperature information of the window area 17. The window detector 110 is electrically connected to the controller 120. After the window detector 110 detects the temperature information in the window area 17, the controller 120 can determine whether the user's limb is located in the window area 17 according to the electrical signal containing the temperature information of the window area 17 sent by the window detector 110, and then control the vehicle window to stop closing or opening, thereby reducing the risk of the user being pinched.

[0080] In a specific solution, the window detector 110 includes at least one of a thermal resistor sensor, a thermistor temperature sensor, and an optical fiber temperature sensor, and those skilled in the art can flexibly set it according to actual usage requirements.

[0081] In some embodiments, the controller 120 includes: a temperature difference judgment module. The temperature difference judgment module is used to judge whether to stop the movement of the vehicle window according to the difference in temperature of the inter-window area 17 at different times. When the vehicle is in use, the temperature of the inter-window area 17 approaches the ambient temperature, and when the user's limbs fall into the inter-window area 17, the temperature in the inter-window area 17 changes due to the intervention of the user's limbs. By setting the temperature difference judgment module, it can be determined whether there is a user's limb in the inter-window area 17, and then the controller 120 is used to control the vehicle window when the user's limbs fall into the inter-window area 17 to prevent the user from being pinched.

[0082] In some embodiments, the temperature difference judgment module includes: a temperature calculation unit and a temperature difference comparison unit. The temperature difference calculation unit is used to calculate the temperature difference of the inter-window area 17 according to the temperature of the inter-window area 17 detected by the inter-window detector 110 at different times. The temperature difference comparison unit is used to compare the temperature difference value of the inter-window area 17 calculated by the temperature difference calculation unit with a preset temperature difference threshold value, so as to control the movement of the vehicle window according to the comparison result.

[0083] In some embodiments, the control system 100 further includes: a Hall sensor 130. The Hall sensor 130 is used to detect the resistance when the vehicle window is driven to move. The Hall sensor 130 is a magnetic field sensor made using the Hall effect, and can be used to sense changes in the magnetic field. The Hall sensor 130 is electrically connected to the controller 120 to send an electrical signal to the controller 120 that contains information about the resistance when the vehicle window moves.

[0084] The control system 100 provided in the present application can cooperate with a lifting motor 210, and the lifting motor 210 drives the window to move through a transmission structure such as a ball screw, a gear rack, etc. The lifting motor 210 can be electrically connected to a lifting circuit 220, and driven by the lifting circuit 220 to form different directions and rotation speeds, thereby realizing the control of the direction and speed of movement of the window. The controller 120 in the control system 100 can be used to control the operation of the lifting motor 210, specifically to form an electrical connection with the lifting circuit 220, and to control the lifting circuit 220 to output an electrical signal to the motor to make the motor generate different speeds and directions by configuring a control signal to the lifting circuit 220, thereby realizing the control of the movement of the window. The Hall sensor 130 mentioned above can be specifically configured to detect the working state of the motor, realize the detection of the resistance encountered when the window moves, and then send an electrical signal to the controller 120 through the Hall sensor 130, so that when the movement of the window is blocked. The controller 120 can be used to control the state of the lifting motor 210 to prevent the window from continuing to close, thereby realizing the anti-pinch function.

[0085] In a specific solution, when the window is driven by the lifting motor 210 and moves, the controller 120 determines whether the window encounters an obstacle based on the pulse width when the Hall sensor 130 is powered on. Take the specific movement form of the window rising to close the window and the window falling to open the window as an example. In the process of the lifting motor 210 driving the window to rise, if an obstacle is encountered so that the window is resisted from rising, the load of the motor becomes larger, the speed of the motor will become slower, and the running current of the motor will become larger. The Hall sensor 130 senses the change in the current on the motor and sends an electrical signal with a corresponding change in pulse width to the controller 120. When the pulse width of the electrical signal sent by the Hall sensor 130 exceeds the set threshold, the controller 120 sends a control instruction to make the lifting circuit 220 drive the lifting motor 210 to control the window to fall, thereby realizing the window anti-pinch function.

[0086] It can be understood that the above-mentioned solution of using the Hall sensor 130 to achieve the anti-pinch function needs to be triggered when the motor is affected by an obstacle and encounters a corresponding amount of resistance during the upward movement. In order to reduce misjudgment, a preset pulse width threshold is often set in the related technology. When the actual pulse width of the Hall sensor 130 is greater than the threshold, that is, the external resistance is not less than a certain threshold, the window is driven down. This solution may often be triggered when the user's limbs have been pinched and create resistance to the movement of the window.

[0087] In the present application, a solution for preventing car windows from being pinched is implemented using a Hall sensor 130, which is used in conjunction with a solution for preventing car windows from being pinched using temperature detection. When the resistance generated by the car window encountering an obstacle is less than a threshold, the temperature deviation of the inter-window area 17 can be detected. This allows preventing car windows from being pinched even when the user's limbs are not pinched between the car window and the vehicle frame, thereby improving safety in use.

[0088] In some embodiments, the control system 100 further includes: an alarm 140. The alarm 140 is used to send an alarm signal when the controller 120 controls the movement of the window. Specifically, the alarm 140 is electrically connected to the controller 120. When the temperature sensor and / or the Hall sensor 130 are used to implement the anti-pinch function, the controller 120 can be used to control the alarm 140 to alarm the user to achieve the purpose of reminding the user. In a specific scheme, the alarm signal sent by the alarm 140 includes at least one of a light signal, a sound signal and an electrical signal. The light signal may be, for example, a strong light emitted into the cabin of the vehicle, the sound signal may be, for example, a buzzing sound, and the electrical signal may be, for example, an alarm message displayed on a corresponding screen for human-computer interaction in the cabin of the vehicle.

[0089] In some embodiments, the control system 100 further includes: an operation switch 150. The operation switch 150 is used for the user to operate to send an electrical signal to the controller 120 to drive the movement of the vehicle window. In a specific solution, the operation switch 150 can be, for example, a corresponding button set in the vehicle cabin, or an operation interface for human-computer interaction to control the lifting of the vehicle on a device such as a touch display in the vehicle cabin, etc. The operation switch 150 is electrically connected to the controller 120. The user sends a corresponding command signal to the controller 120 by using the operation switch 150, and the controller 120 is able to control the opening / closing / stopping of the vehicle window through the received command signal.

[0090] According to the second aspect of the present application, referring to Figure 1 As shown, the present application provides a vehicle window lifting system 200 , including: a lifting motor 210 and the aforementioned control system 100 .

[0091] The lifting motor 210 is used to raise or lower the vehicle window. In some embodiments, the controller 120 receives an electrical signal including temperature information of the window area 17 sent by the window detector 110, and controls the movement of the vehicle window according to the electrical signal including temperature information of the window area 17.

[0092] In a specific solution, in order to enable the controller 120 to receive the electrical signal containing the temperature information of the inter-window area 17 sent by the inter-window detector 110 , the inter-window sensor and the controller 120 are electrically connected.

[0093] In some embodiments, the window lift system 200 further includes a lift circuit 220. The lift circuit 220 is configured to drive the lift motor 210. The lift motor 210 is electrically connected to the lift circuit. The lift circuit is electrically connected to the controller 120.

[0094] In the vehicle window provided by the present application, the lifting motor 210 can be used as the execution part of the aforementioned control system 100 to execute the aforementioned vehicle window anti-pinch function. Specifically, the lifting motor 210, for example, adopts the aforementioned transmission method to achieve transmission coordination with the vehicle window to drive the lifting and lowering of the vehicle window. Correspondingly, the controller 120 controls the use state of the lifting motor 210 through electrical connection with the lifting circuit 220, thereby realizing the lifting and lowering control of the vehicle window. Since the vehicle window lifting system 200 provided by the present application includes the aforementioned control system 100, it has all the beneficial effects of the aforementioned control system 100, which will not be repeated here.

[0095] It is understandable that, based on the inventive concept of the present application, those skilled in the art can flexibly configure the specific structure of the aforementioned control system 100 or the window lifting system 200 at each window of the vehicle to achieve the anti-pinch function. The following will mainly illustrate the specific implementation scheme of the control system 100 provided by the present application when it is configured on a vehicle, so as to clearly explain the inventive concept of the present application.

[0096] For specific plans, refer to Figure 1 As shown, the controller 120 is, for example, a vehicle-mounted microcontroller unit (MCU), which is powered by a vehicle-mounted power supply 230 and is electrically connected to the window detector 110, the Hall sensor 130, the alarm 140, the operating switch 150, the lifting circuit 220, etc. The controller 120 is electrically connected to the lifting circuit 220, and the lifting circuit 220 is also electrically connected to the lifting motor 210. The Hall sensor 130 is configured to be electrically connected to the lifting motor 210 so as to be used to detect the load state of the motor, so that the control system 100 provided in the present application cooperates with the lifting circuit 220 and the lifting motor 210 to constitute at least a part of the aforementioned vehicle window lifting system 200.

[0097] For more specific solutions, refer to Figure 2 , Figure 3 and Figure 4As shown, when the aforementioned control system 100 or the window lifting system 200 is integrated into a vehicle, an anti-pinch strip 11 with an embedded window detector 110 can be further provided on the upper edge of the window 14. The anti-pinch strip 11 is made of a flexible material such as rubber, so that even if the user's limbs are pinched when closing the window, a cushioning effect can be provided to reduce damage. A window detector 110 is arranged in the anti-pinch strip 11 to monitor the edge temperature of the vehicle window 14 in real time. The transmission wire 12 connects the controller 120 and the window detector 110. The edge temperature of the vehicle window 14 detected by the window detector 110 is input into the controller 120. Temperature calculation and comparison are performed in the temperature calculation unit and the temperature difference comparison unit. The current temperature is subtracted from the last detected temperature. When the Hall sensor 130 detects that the vehicle window 14 rises and the vehicle window 14 has not reached the end of the preset rising stroke, the absolute value of the temperature deviation is compared with the preset temperature difference threshold. When the deviation value is greater than or equal to the temperature difference threshold, the vehicle window anti-pinch function is activated, and the motor stops driving the vehicle window 14 to move up. At this time, the anti-pinch function can be achieved by stopping the vehicle window 14 from moving or driving the vehicle window 14 to move down by the lifting motor 210. Furthermore, the alarm 140 is controlled by the controller 120 to send out an alarm message. The alarm 140 is, for example, a buzzer. When the anti-pinch function is activated, the buzzer is sent into the vehicle cabin to remind the user in the vehicle cabin in the form of a sound signal. After the anti-pinch function is realized, the above anti-pinch function can be continued. During this period, the user can control the buzzer to stop working by operating the button or the human-machine interface by configuring a corresponding button or human-machine interface in the vehicle cabin. After the anti-pinch function is realized, the controller 120 stops until it receives the command signal of the control switch 150 to control the window 14 to rise or fall again, and then the window 14 performs the corresponding rising or falling action.

[0098] In some solutions, the controller 120 may be further electrically connected to the bus communication module 13 on the vehicle, so that the controller 120 can communicate with other electronic control modules on the vehicle. Specifically, the solution may be used to determine whether the window 14 meets the conditions for performing the lifting action. As an example, the bus communication module 13 is electrically connected to the corresponding electronic control module for controlling the child lock on the vehicle, so as to determine whether the window 14 performs the lowering action when the user uses the operating switch 150 in combination with the start and stop state of the child lock.

[0099] In some schemes, after the MCU detects the command signal provided by the operating switch 150, if the window meets the conditions for executing the action, the MCU sends an electrical signal to the lifting circuit 220, and the lifting circuit 220 controls the lifting motor 210 to rotate forward or reverse to control the window to rise or fall. In order to reduce the impact sound caused by the window closing speed being too fast and the frame surrounding the window on the vehicle, the MCU uses pulse width modulation (PWM) control to control the motor speed, that is, by changing the duty cycle output by the MCU to change the on-off time of the lifting circuit 220, thereby changing the average voltage of the terminal for supplying power to the stator on the lifting motor 210. When the average voltage of the terminal is reduced, the speed of the lifting motor 210 slows down, thereby realizing the slow closing of the window, reducing the noise when closing the window, and further reducing the possibility of the user being pinched.

[0100] In some alternatives, reference Figure 5 As shown, the anti-pinch strip 11 can be configured to be set on the frame of the vehicle door 15 that surrounds the vehicle window, and specifically can be set at the upper frame that contacts the vehicle window when the vehicle window is closed. Before the vehicle window moves up and contacts the upper frame of the vehicle door 15, if the user's limbs are near the anti-pinch strip 11, the temperature change of the window area 17 can be detected by the window detector 110 set on the anti-pinch strip 11, and then a corresponding electrical signal is sent to the controller 120. The controller 120 is able to control the state of the lifting motor 210 to achieve the anti-pinch function. At this time, the transmission wire 12 connected to the window detector 110 does not need to move with the vehicle window 14.

[0101] In some other options, refer to Figure 6 As shown, considering the case where the door has no upper frame, the anti-pinch strip 11 can also be set on the frame of the vehicle body 16, and the frame of the vehicle body 16 is configured to be combined with the window 14 when the door 15 is closed and the window 14 is closed. This solution is suitable for the vehicle model with no upper frame of the door 15, and the transmission wire 12 connected to the window detector 110 does not need to move with the window 14.

[0102] According to the third aspect of the present application, referring to Figure 7 As shown, a control method is provided for controlling the operation of a vehicle window, the control method comprising:

[0103] S100 , controlling the movement of the vehicle windows according to the temperature of the area 17 between the windows.

[0104] The control method provided in the present application associates the movement of the vehicle window with the temperature of the area 17 between the windows. When the vehicle window is closed but the user's limbs are present in the area 17 between the windows, the vehicle window stops moving or is opened, and the user's limb information can be detected relatively directly to realize the anti-pinch function.

[0105] In some embodiments, step S100 includes:

[0106] S110', when the temperature of the area 17 between the windows meets the preset condition, the movement of the vehicle windows is stopped.

[0107] In some embodiments, S110' includes:

[0108] S111', when the temperature change of the area between the windows 17 meets the preset conditions within the preset time period, the movement of the vehicle windows is stopped.

[0109] As a specific solution, step S100 includes:

[0110] S110 , detecting the temperature of the area 17 between windows.

[0111] S120 , stopping the movement of the vehicle windows according to the temperature of the area 17 between the windows.

[0112] In some embodiments, step S120 includes:

[0113] S121. Determine whether to stop raising the vehicle windows according to the temperature difference of the inter-window area 17.

[0114] As shown in the figure, in actual use, the ambient temperature is often different from the temperature of human limbs. By detecting the temperature difference in the window area 17, it is possible to determine whether there are human limbs in the window area 17, or whether there are other debris that may prevent the window from closing. The temperature difference is then used to determine whether to stop the window from rising. This judgment method is different from the related art of determining whether the window has the possibility of pinching the user through mechanical sensing when the window is closed, thereby providing a different idea for window anti-pinch.

[0115] In some embodiments, step S121 includes:

[0116] S1211, determining whether the temperature difference of the inter-window area 17 is greater than a preset difference threshold;

[0117] S1212: When the temperature difference of the inter-window area 17 is greater than a preset difference threshold, stop raising the window.

[0118] Like this, by setting a preset difference threshold, when the temperature difference is detected, it is further compared with the preset difference threshold. Only when the conditions are met will it be determined that there is a possibility of the window pinching a person and the window will be further controlled to stop rising.

[0119] Optionally, in some other embodiments, step S121 includes:

[0120] S1213, determining whether the maximum difference of the temperature of the inter-window area 17 within a preset time period is greater than a preset difference threshold;

[0121] S1214: When the maximum difference of the temperature of the inter-window area 17 within a preset time period is greater than a preset difference threshold, stop raising the window.

[0122] Like this, a solution is adopted to determine whether the window stops rising within a preset time period. By limiting the time condition, the possibility of the vehicle misjudging the existence of a human body being pinched due to changes in the external ambient temperature is reduced, thereby improving the accuracy of the control method in controlling the operation of the window.

[0123] The above generally describes the main idea of ​​the control method provided by the present application for controlling the operation of the vehicle window. The following mainly describes the specific steps of some specific implementation schemes when the control method is implemented on a vehicle as an exemplary illustration of the inventive concept of the present application. Figure 8 and Fig. 9 As shown, taking the example of being able to close the window when it is raised and open the window when it is lowered, the control method provided in the present application can be implemented on the vehicle through the following specific steps.

[0124] As shown in step S801, the controller determines whether it receives a command signal from the operating switch, that is, determines whether the user has a need to open or close the window.

[0125] As shown in S802, when the user uses the operating switch, the controller determines whether the command signal given by the operating switch indicates that the window is to be raised. If so, the controller goes to step S803, and if not, the controller goes to step S901.

[0126] As shown in steps S803 to S807, when the controller determines that the command signal given by the operating switch indicates that the window is rising, the corresponding actuator on the vehicle (such as the lifting motor mentioned above) drives the window to move up; when the window moves up, the window sensor detects the window temperature T0, and after a certain time interval, the window sensor detects the window temperature T1 again.

[0127] As shown in step S808 , the controller obtains the temperature difference ΔT of the inter-window area 17 within a preset time by calculation, and the difference takes the absolute value of the actual value, that is, ΔT=|T0−T1|.

[0128] As shown in step S809, the controller compares the temperature difference ΔT of the inter-window area 17 within the preset time with the preset difference threshold T P If ΔT<T P , go to step S811; if ΔT ≥ T P , then go to step S810.

[0129] As shown in step S810, when ΔT ≥ T PWhen the controller determines that the user's limbs may be in the window area 17, so that the window continues to move up and there is a possibility that the user's limbs will be clamped. At this time, the lifting motor no longer drives the window to move up until the controller receives the command signal of the operation switch again.

[0130] As shown in step S811 and step S812, when ΔT<T P When the user's body is no longer in the window area 17, the window continues to move upward. During the upward movement, it is determined whether the window has moved to the end of the upward travel. The end of the upward travel may be, for example, the position of the window when the window is completely closed, or a specific position designated by the user for the window to stop when it is raised. If the window has not moved to the end of the upward travel, the process proceeds to step S804.

[0131] As shown in step S813, if the window moves up to the end of the ascending stroke, the lifting motor stops driving the window.

[0132] Reference Fig. 9 As shown, when the controller determines that the command signal given by the operating switch does not indicate that the window is raised, referring to step S901, the controller determines that the command signal is a window lowering signal.

[0133] Referring to steps S902 to S904, after the controller determines that the command signal is a window lowering signal, the lifting motor drives the window to move downward. During the process, the controller determines whether the window has moved downward to the end of the lowering stroke. If not, it goes to step S902; if yes, it goes to step S904. It can be understood that the end of the lowering stroke can be, for example, the position of the window when the window is fully opened, or a specific position specified by the user for the window to stop when it is lowered. Referring to step S904, after the controller determines that the window has moved downward to the end of the lowering stroke, the lifting motor stops driving the window.
