Description
Technical Field
The invention relates to the field of automobiles, in particular to a method and a system for reducing clamping force of window glass.
Background
A window glass is an important component of a vehicle, which is generally provided in a door (e.g., front door, rear door) and is provided with a one-key lift function. When a passenger operates the lifting switch, the driving motor is electrified to drive the window glass to descend, and the top edge of the window glass is far away from the window frame or the door frame to open the window so as to realize ventilation; or to drive the window glass up and down, at which time contact between the top edge of the window glass and the window frame or door sash closes the window to prevent ventilation. Since the window glass adopts a one-key lifting scheme, when a passenger operates a lifting switch to allow a driving motor to drive the window glass, the window glass needs to be lifted to the highest position to stop, and a plurality of problems need to be paid attention to the process. For example, if a passenger's limb (especially, a finger or a neck of a child) abuts on the top edge of the window glass, the passenger's limb is lifted up synchronously when the window glass is driven to lift by the driving motor, and this process is not noticeable to the passenger, and the passenger can only detect when the passenger's limb is clamped between the top edge of the window glass and the window frame or the door frame, but since the window glass is continuously driven to lift by the driving motor, even if the passenger can react quickly when the passenger detects that the limb is clamped between the top edge of the window glass and the window frame or the door frame, it is difficult to remove the limb from between the top edge of the window glass and the window frame or the door frame, and the limb is easily injured.

Referring to fig. 1 of the drawings accompanying this specification, a clamping force reduction system 100 according to a preferred embodiment of the present invention is disclosed and illustrated in the following description, wherein the clamping force reduction system 100 can be applied to a vehicle 200 shown in fig. 2 to 5.
When a driving mechanism 210 of the vehicle 200 drives a window glass 220 to rise to close the window, the clamping force reduction system 100 can determine whether an obstacle 300 exists between the window glass 220 and a window frame or door frame 230 of the vehicle 200. If the clamping-force reduction system 100 determines that the obstacle 300 does not exist between the window glass 220 and the window or door frame 230, the clamping-force reduction system can control the driving mechanism 210 to continue operating to continuously drive the window glass 220 to ascend, and conversely, if the clamping-force reduction system 100 determines that the obstacle 300 exists between the window glass 220 and the window or door frame 230, the clamping-force reduction system 100 can control the driving mechanism 210 to stop operating to prevent the window glass 220 from ascending.
Specifically, in some possible examples, the obstacle 300 is a limb of a passenger, such as a finger or a neck of an infant, and when the clamping force reduction system determines that there is a limb of a passenger between the window glass 220 and the window frame or door frame 230, the clamping force reduction system can control the driving mechanism 210 to stop working to prevent the window glass 220 from rising, so as to reduce or avoid the clamping force formed between the window glass 220 and the window frame or door frame 230, thereby reducing or avoiding injury to the passenger.
In other possible examples, the obstacle 300 is an object, and when the clamping force reduction system 100 determines that an object exists between the window pane 220 and the window or door frame 230, the clamping force reduction system can control the driving mechanism 210 to stop working to prevent the window pane 220 from rising, so as to reduce the clamping force formed between the window pane 220 and the window or door frame 230, thereby reducing or avoiding damage to the object and/or the window pane 220.
Preferably, the clamping force reduction system of the present invention determines whether the obstacle 300 exists between the window glass 220 and the window frame or door frame 230 based on the sound of the inside of the vehicle 200, that is, the clamping force reduction system of the present invention may externally connect at least one sound receiver 240, such as a microphone, inside the vehicle 200, the sound receiver 240 is configured to receive the sound of the inside of the vehicle 200 during the process that the driving mechanism 210 drives the window glass 220 to ascend, and subsequently, the clamping force reduction system 100 may determine whether the obstacle 300 exists between the window glass 220 and the window frame or door frame 230 according to the sound of the inside of the vehicle 200 received by the sound receiver 240.
For example, in one embodiment of the clamping force reduction system 100 of the present invention, the sound receiver 240 is disposed inside the vehicle 200 to allow the sound receiver 240 to receive sounds made by passengers. Specifically, when the top edge of the window glass 220 and the window frame or door frame 230 have a large distance to place the vehicle 200 in a window opening state, the hand of the passenger can abut against the top edge of the window glass 220; when the driving mechanism 210 drives the window glass 220 to ascend, the window glass 220 can synchronously ascend with the hands of passengers; when the window glass 220 and the window or door frame 230 start to sandwich the hand of the passenger, the sound receiver 240 can receive the sound from the passenger because the passenger feels that the hand is sandwiched between the window glass 220 and the window or door frame 230 to generate a sound, for example, a scream sound, and subsequently, the clamping force reduction system 100 can determine that the hand of the passenger is sandwiched between the window glass 220 and the window or door frame 230 based on the sound generated by the passenger received by the sound receiver 240.
In order to improve the accuracy of the clamping force reduction system 100 based on the judgment result of the sound emitted by the passenger received by the radio receiver 240, in some embodiments, the clamping force reduction system 100 may train a reference model based on a deep learning technique, and subsequently the clamping force reduction system 100 may input the sound emitted by the passenger received by the radio receiver 240 into the reference model, so as to judge whether the passenger's limb is clamped by the window glass 220 and the window frame or the door frame 230.
It can be understood that the clamping force reduction system 100 of the present invention can greatly improve the sensitivity of the clamping force reduction system 100 by determining whether the passenger's limb is clamped by the window glass 220 and the window frame or door frame 230 based on the sound emitted from the passenger, thereby reducing or preventing the injury to the passenger and the damage to the object and/or the window glass due to the closing of the window.
It is worth mentioning that the number of the sound receivers 240 and the positions where the sound receivers 240 are disposed are not limited in the clamping force reduction system 100 of the present invention. For example, in a typical example, the number of the sound receivers 240 may be four or four, which are respectively disposed at positions of the roof of the vehicle 200 corresponding to each window seating, such that each or each group of the sound receivers 240 can respectively receive sounds emitted from passengers near the windows of the vehicle.
In another embodiment of the clamping force reducing system 100 of the present invention, the sound receiver 240 is disposed adjacent to a driving motor 211 of the driving mechanism 210 of the vehicle 200, and the sound receiver 240 is allowed to receive an operating sound of the driving motor 211 of the driving mechanism 210 when the driving motor 211 drives the window glass 220 to ascend by transmitting power to the window glass 220 through a transmission portion 212 of the driving mechanism 210.
Specifically, when the driving motor 211 of the driving mechanism 210 transmits power to the window glass 220 through the transmission portion 212 to drive the window glass 220 to ascend, if the obstacle 300 is not clamped between the window glass 220 and the window frame or door frame 230, the driving motor 211 can smoothly output power to generate crisp sound, and if the obstacle 300 is clamped between the window glass 220 and the window frame or door frame 230, the driving motor 211 outputs power to generate clunky sound. By disposing the radio 240 adjacent to the driving motor 211, the radio 240 can receive the operation sound of the driving motor 211 in the whole process that the driving motor 211 of the driving mechanism 210 outputs the power to the window glass 220 through the transmission portion 212 to drive the window glass 220 to ascend, and subsequently, the clamping force reducing system 100 can determine whether the obstacle 300 exists between the window glass 220 and the window frame or the door frame 230 according to the change state of the operation sound of the driving motor 211.
More specifically, throughout the process in which the drive motor 211 of the drive mechanism 210 outputs power to the window glass 220 through the transmitting portion 212 to drive the window glass 220 to rise, if the operating sound of the drive motor 211 remains crisp, the clamping-force reduction system 100 may determine that the obstacle 300 is not present between the window glass 220 and the window or door frame 230, and if the operating sound of the drive motor 211 suddenly becomes clunky, the clamping-force reduction system 100 may determine that the obstacle 300 is suddenly pinched between the window glass 220 and the window or door frame 230.
It can be understood that the clamping force reduction system 100 of the present invention can greatly improve the sensitivity of the clamping force reduction system 100 by determining whether the obstacle 300 is clamped between the window glass 220 and the window or door frame 230 based on the sound emitted from the driving motor 211 of the driving mechanism 210, thereby reducing or preventing the injury of passengers and the damage of objects and/or the window glass 220 due to the window being closed.
In order to reduce or avoid the interference of noise and to enable the sound receiver 240 to reliably receive the operating sound of the driving motor 211 of the driving mechanism 210, the driving mechanism 210 further includes a sound-proof housing 213, the sound-proof housing 213 irradiates the outside of the driving motor 211, and a sound-proof space 214 is formed between the sound-proof housing 213 and the driving motor 211, and the sound receiver 240 is disposed in the sound-proof space 214. For example, the open end of the soundproof case 213 is locked to one end of the driving motor 211 so that the main body portion of the driving motor 211 is held inside the soundproof case 213, and the soundproof space 214 is formed with a gap between the outer wall of the driving motor 211 and the inner wall of the soundproof case 213, and the sound receiver 240 may be mounted to the soundproof case 213 or the driving motor 211 so that the sound receiver 240 is held in the soundproof space 214, so that the sound receiver 240 can receive the operation sound from the driving motor 211 in the soundproof space 214.
Preferably, the soundproof case 213 is made of a sound absorbing material, or the inner wall of the soundproof case 213 is provided with a sound absorbing layer, so that the sound wave generated by the driving motor 211 in operation is absorbed by the soundproof case 213 when radiated to the inner wall of the soundproof case 213, to reduce the amount of the sound wave reflected from the inner wall of the soundproof case 213 toward the sound receiver 240 or to prevent the inner wall of the soundproof case 213 from reflecting the sound wave toward the sound receiver 240, which is advantageous for improving the accuracy of the result of the clamping force reduction system 100 judging whether the obstacle 300 is present between the window glass 220 and the window frame or door frame 230 based on the operation sound of the driving motor 211 received by the sound receiver 240.
In some embodiments of the clamping force reduction system 100 of the present invention, the clamping force reduction system 100 is configured to associate the operating state of the sound receiver 240 with the operating state of the drive mechanism 210 to allow the sound receiver 240 to be in an operating state to receive sound from the interior of the vehicle 200 before the drive mechanism 210 drives the window glass 220 up. In other embodiments of the clamping force reduction system 100 of the present invention, the clamping force reduction system 100 is configured to associate the operating state of the sound receiver 240 with the operating state of the drive mechanism 210 to allow the sound receiver 240 to be in an operating state to receive sound from the interior of the vehicle 200 when the drive mechanism 210 drives the window glass 220 up.
In other words, whether the sound receiver 240 is allowed to be in the operating state before the driving mechanism 210 drives the window glass 220 to ascend or the sound receiver 240 is allowed to be in the operating state when the driving mechanism 210 drives the window glass 220 to ascend, when the driving mechanism 210 starts to drive the window glass 220 to ascend, the clamping force reduction system 100 of the present invention always allows the sound receiver 240 to be in the operating state to receive the sound inside the vehicle 200 until the window of the vehicle 200 is closed.
It is worth mentioning that the clamping force reduction system 100 of the present invention is not limited in the manner of associating the operating state of the radio 240 with the operating state of the driving mechanism 210. For example, in a typical example of the clamping force reduction system 100, the driving motor 211 and the sound receiver 240 of the driving mechanism 210 are both connected to a lift switch, for example, the sound insulation shell 213 of the driving mechanism 210 may reserve a bus through hole, one end of a CAN bus extends to the sound insulation space 214 after passing through the bus through hole of the sound insulation shell 213 to be able to be connected to the driving motor 211 and the sound receiver 240, and the other end of the CAN bus may be connected to the lift switch through a running computer of the vehicle 200, the clamping force reduction system 100 is a system or program running on the running computer of the vehicle 200, and when a passenger operates the lift switch, the clamping force reduction system 100 may firstly send a command to the sound receiver 240 to allow the sound receiver 240 to be switched from an off state or a sleep state to an operating state, and secondly send a command to the driving motor 211 of the driving mechanism 210 to allow the driving motor 211 to be switched from the off state or the sleep state to the operating state, so that the clamping force reduction system 100 CAN correlate the operating state of the sound receiver 240 and the operating state of the driving mechanism 210.
It is worth mentioning that the type of the lifting switch is not limited in the clamping force reduction system 100 of the present invention, and may be a mechanical switch or a virtual switch.
For example, in a specific example of the clamping force reduction system 100 of the present invention, the clamping force reduction system 100 may control the operation states of the driving motor 211 of the driving mechanism 210 and the radio 240 by externally connecting a camera 250 of the vehicle 200, wherein the camera 250 may be a camera configured inside the vehicle 200 and used for photographing a driver to determine the driving state of the driver.
Specifically, first, the clamping force reduction system 100 allows the camera 250 to capture a gesture image of the driver, for example, when the driver makes a hand-waving motion in the air, the clamping force reduction system 100 can capture a picture or video of the hand-waving motion in the air made by the driver through the camera 250. Next, the clamping force reduction system 100 generates a control command for controlling the driving mechanism 210 and the radio 240 according to the gesture image of the driver captured by the camera 250, and if the control command is to make the driving mechanism 210 drive the window glass 220 to descend, the radio 240 is kept in a non-operating state, and if the control command is to make the driving mechanism 210 drive the window glass 220 to ascend, the radio 240 is switched to an operating state.
In other words, when the clamping force reduction system 100 determines that the driver intends to open the window according to the finger image of the driver captured by the camera 250, since the obstacle 300 is not clamped between the window glass 220 and the window frame or the door frame 230 during the window opening process, the clamping force reduction system 100 allows the radio 240 to be maintained in a non-operating state, so as to reduce energy consumption and prolong the service life of the radio 240. When the clamping force reduction system 100 determines that the driver intends to close the window based on the finger image of the driver captured by the camera 250, since there is a risk that the obstacle 300 is clamped between the window glass 220 and the window frame or door frame 230 during the window closing process, the radio receiver 240 is switched to the operating state before the driving motor 211 of the driving mechanism 210 is switched to the operating state, which is advantageous for the following cases: in the case of a small gap between the window glass 220 and the window or door frame 230, a child may put his fingers in the small gap between the window glass 220 and the window or door frame 230, which is advantageous to greatly shorten the time for the clamping force reduction system 100 to judge that the obstacle 300 is present between the window glass 220 and the window or door frame 230 during the closing process by switching the radio 240 to the operating state before the driving motor 211 of the driving mechanism 210 is switched to the operating state, thereby reducing or avoiding injury to passengers.
In another specific example of the clamping force reduction system 100 of the present invention, the clamping force reduction system 100 may control the operation states of the driving motor 211 and the radio 240 of the driving mechanism 210 by externally connecting a touch screen 260 of the vehicle 200, wherein the touch screen 260 may be a screen configured at a console position of the vehicle 200.
Specifically, first, the clamping force reduction system 100 may detect the number of fingers of the passenger contacting the touch screen 260 and detect the moving track of the fingers of the passenger on the touch screen 260 to detect the gesture action of the passenger. Next, the clamping force reduction system 100 generates a control command for controlling the driving mechanism 210 and the radio 240 according to the gesture motion of the passenger, and if the control command is to make the driving mechanism 210 drive the window glass 220 to descend, the radio 240 is kept in a non-operating state, and if the control command is to make the driving mechanism 210 drive the window glass 220 to ascend, the radio 240 is switched to an operating state.
In other words, when the clamping force reduction system 100 determines that the purpose of the passenger is to open the window according to the gesture action of the passenger, since there is no situation in which the obstacle 300 is clamped between the window glass 220 and the window frame or door frame 230 during the window opening process, the clamping force reduction system 100 allows the radio 240 to be maintained in a non-operating state, so as to reduce energy consumption and prolong the service life of the radio 240. When the clamping force reduction system 100 judges that the purpose of the passenger is to close the window according to the finger action of the passenger, since there is a risk that the obstacle 300 is clamped between the window glass 220 and the window frame or door frame 230 during the window closing process, the radio 240 is switched to the operating state before the driving motor 211 of the driving mechanism 210 is switched to the operating state, which is advantageous for the following cases: in the case of a small gap between the window glass 220 and the window or door frame 230, a child may put his fingers in the small gap between the window glass 220 and the window or door frame 230, which is advantageous to greatly shorten the time for the clamping force reduction system 100 to judge that the obstacle 300 is present between the window glass 220 and the window or door frame 230 during the closing process by switching the radio 240 to the operating state before the driving motor 211 of the driving mechanism 210 is switched to the operating state, thereby reducing or avoiding injury to passengers.

The main processor 110 of the clamping force reduction system 100 may be permanently configured or temporarily configured with a plurality of units, which may include a sound receiving unit 10, a judging unit 20, and a control unit 30.
In other words, the clamping force reduction system 100 of the present invention includes the sound pickup unit 10, the determination unit 20, and the control unit 30, and the sound pickup unit 10, the determination unit 20, and the control unit 30 are communicably connected to each other. The sound receiving unit 10 is used for receiving the sound inside the vehicle 200 during the process that the driving mechanism 210 drives the window glass 220 to ascend. The judging unit 20 is configured to judge whether the obstacle 300 exists between the window glass 220 and the window frame or the door frame 230 according to the sound received by the sound receiving unit 20. The control unit 30 is configured to control an operating state of the driving mechanism 210 according to a determination result of the determining unit 20, wherein if the obstacle 300 does not exist between the window glass 220 and the window frame or door frame 230, the control unit 30 controls the driving mechanism 210 to continue operating to continuously drive the window glass 220 to ascend, and if the obstacle 300 exists between the window glass 220 and the window frame or door frame 230, the control unit 30 controls the driving mechanism 210 to stop the window glass 220 from ascending, so as to reduce or avoid injury to passengers and damage to objects and/or the window glass.
Preferably, the sound receiving unit 10 may be externally connected to the sound receiver 240 of the vehicle 200, and during the process that the driving mechanism 210 drives the window glass 220 to ascend, the sound receiver 240 is used for receiving the sound inside the vehicle 200, and the sound inside the vehicle 200 received by the sound receiver 240 may be transmitted to the main processor 110 through a communication module (e.g., a CAN bus) to be acquired by the sound receiving unit 10. Subsequently, the determination unit 20 may determine whether the obstacle 300 exists between the window glass 220 and the window frame or the door frame 230 according to the sound received by the sound receiving unit 10.
It should be noted that the specific manner of the sound content received by the sound receiving unit 10 and the judgment unit 20 judging whether the obstacle 300 exists between the window glass 220 and the window frame or door frame 230 according to the sound received by the sound receiving unit 10 is determined according to the position where the sound receiver 240 is disposed.
For example, in one embodiment of the clamping force reduction system 100 of the present invention, referring to fig. 2 to 5, the sound receivers 240 are disposed at positions corresponding to each window seat of the roof of the vehicle 200, such as the tops of the a-pillars and/or the B-pillars, so as to allow each or each group of the sound receivers 240 to respectively receive the sound emitted by the passenger near the window, i.e., the content of the sound received by the receiving unit 10 through the sound receivers 240 is the sound emitted by the passenger. Subsequently, the determining unit 20 can determine that the hand of the passenger is clamped between the window glass 220 and the window frame or door frame 230 according to the sound emitted by the passenger received by the radio 240, for example, when the passenger suddenly makes a scream in the process of closing the window, the determining unit 20 can determine that the limb of the passenger is clamped between the window glass 220 and the window frame or door frame 230.
For another example, in another embodiment of the clamping force reducing system 100 of the present invention, with continued reference to fig. 2 to 5, the sound receiver 240 is disposed adjacent to the driving motor 211 of the driving mechanism 210, for example, the sound receiver 240 is disposed in the sound insulation space 214 formed between the driving motor 211 and the sound insulation shell 213, so as to allow the sound receiver 240 to receive the operation sound of the driving motor 211 of the driving mechanism 210, that is, the content of the sound received by the sound receiver 240 through the sound receiver 10 is the operation sound emitted by the driving motor 211 of the driving mechanism 210. Subsequently, the judging unit 20 can judge whether the obstacle 300 is sandwiched between the window glass 220 and the window frame or the door frame 230 according to the sound emitted by the driving motor 211 received by the radio 240, for example, when the operating sound emitted by the driving motor 211 of the driving mechanism 210 suddenly becomes boring during the window closing process, the judging unit 20 can judge that the obstacle 300 is sandwiched between the window glass 220 and the window frame or the door frame 230.

The command generating unit 50 is configured to generate a control command for controlling the driving mechanism 210 according to the gesture image acquired by the acquiring unit 40, wherein if the control command is to make the driving mechanism 210 drive the window glass 220 to descend, the radio 240 is kept in a non-operating state, and if the control command is to make the driving mechanism 210 drive the window glass 220 to ascend, the radio 240 is switched to an operating state.
In other embodiments of the clamping force reduction system 100 of the present invention, the obtaining unit 40 is configured to obtain the gesture action of the driver through the touch screen 260, for example, when the driver contacts a specific number of fingers (for example, two or three fingers) with the touch screen 260 and moves along a specific movement track (for example, upward or obliquely upward, downward or obliquely downward), the obtaining unit 40 may obtain the gesture action of the driver according to the number of fingers contacting the touch screen 260 and the movement track of the fingers on the touch screen 260. The instruction generating unit 50 is configured to generate a control instruction for controlling the driving mechanism 210 according to the gesture motion acquired by the acquiring unit 40, wherein if the control instruction is to make the driving mechanism 210 drive the window glass 220 to descend, the radio 240 is kept in a non-operating state, and if the control instruction is to make the driving mechanism 210 drive the window glass 220 to ascend, the radio 240 is switched to an operating state.

For example, in some embodiments, the reminding unit 60 may be externally connected to a decorative lamp of the vehicle 200, and when the determining unit 20 determines that the obstacle 300 is present between the window glass 220 and the window frame or the door frame 230, on one hand, the control unit 30 controls the driving mechanism 210 to stop and prevent the window glass 220 from ascending, and on the other hand, the reminding unit 60 reminds the driver by changing the operating state of the decorative lamp of the vehicle 200. In other embodiments, the reminding unit 60 may be externally connected to the touch screen 260 of the vehicle 200, and when the determining unit 20 determines that the obstacle 300 is present between the window glass 220 and the window frame or the door frame 230, on one hand, the control unit 30 controls the driving mechanism 210 to stop and prevent the window glass 220 from ascending, and on the other hand, the reminding unit 60 reminds the driver by displaying reminding content on the touch screen 260.

The fault tolerant unit 70 is configured to perform fault tolerance on the determination result of the determining unit 20, so as to improve the reliability of the clamping force reducing system 100.
Specifically, when the driving mechanism 210 drives the window glass 220 to ascend to close the window, on one hand, the sound pickup unit 10 may receive the operation sound emitted by the driving motor 211 of the driving mechanism 210 through at least one sound pickup 240, and accordingly, the determination unit 20 may determine whether the obstacle 300 is present between the window glass 220 and the window frame or the door frame 230 according to the operation sound emitted by the driving motor 211, and on the other hand, the sound pickup unit 10 may receive the sound emitted by the passenger inside the vehicle 200 through at least one sound pickup 240 in the same time period, and accordingly, the determination unit 20 may determine whether the obstacle 300 is present between the window glass 220 and the window frame or the door frame 230 according to the sound emitted by the passenger. In order to improve the reliability of the clamping force reduction system 100, the fault-tolerant unit 70 performs fault-tolerant processing on the determination result of the determination unit 20 based on the operation sound generated by the driving motor 211 and on the determination result of the determination unit 20 based on the sound generated by the passenger inside the vehicle 200. In other words, as long as one of the determination results of the determination unit 20 based on the operation sound emitted by the driving motor 211 and the determination result of the determination unit 20 based on the sound emitted by the passenger inside the vehicle 200 is that the obstacle 300 is present between the window glass 220 and the window frame or door frame 230, the control unit 30 may control the driving mechanism 210 to stop and prevent the window glass 220 from rising, thus reducing or avoiding injury to the passenger and damage to an object and/or the window glass.
