[0056] The embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be construed as being limited to the embodiments described herein. Instead, these embodiments are provided to provide a more thorough and complete understanding of the present application. It should be understood that the drawings and embodiments of the present application are only for exemplary purposes and are not intended to limit the scope of protection of the present application.

[0057] It should be understood that the various steps described in the method implementation of the present application can be performed in different orders and / or performed in parallel. In addition, the method implementation may include additional steps and / or omit the steps shown. The scope of the present application is not limited in this respect.

[0058] As described in the background technology section, with the development of automobile technology, more and more vehicles are using frameless windows to enhance the aesthetics and technological sense of the vehicle. However, for vehicles currently equipped with frameless windows, users need to manually lower the window before opening the door, and then perform the door opening action. This two-step operation process is cumbersome, which in turn affects the overall user experience.

[0059] In addition, the above-mentioned vehicles use frameless windows to replace framed windows, which also gave rise to a variety of door opening methods to meet the control needs of windows. However, the existing window control methods only use some methods to control windows, which has certain limitations. For example, some methods rely on installing an identification device on the door handle, and control the frameless windows through the door opening signal received by the device, which not only has high requirements on the door handle, but also increases the manufacturing cost of the whole vehicle; or the method of collecting the door opening signal to control the frameless windows through the body controller cannot cover all the door opening methods. Therefore, the above method has the problem of not being able to take into account the various door opening methods to control the frameless windows, which in turn affects the convenience of users.

[0060] Therefore, the present application provides a technical solution for a window control method of a frameless door. Figure 1 Schematic diagram of the flow of the window control method of the frameless door provided in the embodiment of the present application, such as Figure 1 As shown, the following steps are included:

[0061] Step 101: Receive a door lock unlocking signal and a door opening associated signal of a vehicle, and control a vehicle window to descend when at least one of the door lock unlocking signal and the door opening associated signal is received.

[0062] The technical solution provided by the embodiment of the present application can control the window of the frameless door to be lowered according to a variety of door opening signals, such as a door lock opening signal and a door opening associated signal, so that the window can be lowered to a suitable position and no longer affect the door opening. In this embodiment, when a door opening signal is received again, the window can be directly controlled to be lowered, thereby automatically preparing for the subsequent frameless door opening, which can not only simplify the operation of the user opening the vehicle door, but also improve the accuracy and stability of the lowering of the window of the frameless door, thereby effectively reducing the wear and tear of the window and greatly improving the overall user experience.

[0063] The window control method of a frameless door provided in the embodiment of the present application can be implemented by a corresponding window controller. When the window of a frameless door is controlled by the above method, it is necessary to first receive a door lock opening signal and a door opening associated signal, and then use at least one of the received door lock opening signal and door opening associated signal to control the window to drop. The above process of controlling the window to drop is actually a process of finely adjusting the position outside the window, aiming to drop the window to a suitable position that is neither worn nor easy for passengers to enter and exit, for example, controlling the closed window to drop 18mm.

[0064] The technical solution provided in the embodiments of the present application can take into account various door opening signals. For example, the above-mentioned door lock opening signal refers to an electrical signal that triggers the unlocking of the vehicle door lock, which can be triggered by factors such as the vehicle key, remote control operation, sensor detection inside the vehicle, and the vehicle's automatic decision-making system. For example, when the vehicle's security system or smart entry system recognizes that an authorized key or card is approaching the vehicle, it will automatically trigger the door lock opening signal; the door opening associated signal is an electrical signal used to indicate that the door should be opened, which can be triggered by a variety of factors, such as the driver's operation, the passenger's request, and the vehicle system's automatic decision made based on preset logic or scenarios.

[0065] As described above, using this method to control the lowering of the window of a frameless door can not only simplify the operation of opening the vehicle door for the user, but also improve the accuracy and stability of the lowering of the window of the frameless door, thereby effectively reducing the wear and tear of the window while greatly improving the user's overall experience.

[0066] In some embodiments, when receiving the vehicle's door lock opening signal, it can be received through a hardware circuit. At this time, the door lock opening signal received is a high-low level signal. Receiving the door lock opening signal through the hardware circuit can ensure the stable transmission of the signal, reduce the possibility of signal interference and loss, and achieve a faster response time, ensuring that the vehicle safety system can respond to the door lock state in real time. The above-mentioned hardware circuit is a physical path for transmitting signals or data, which can be used to connect the door lock device with the vehicle's control system to achieve signal transmission, including a physical path composed of wires, cables and other transmission media that directly connect the door lock and the vehicle control system; high and low level signals are basic signal forms used to represent binary data in digital circuits, including high level signals and low level signals, wherein the high level signal often represents a logical "1" or "true" state, representing a specific logic or data state, for example, the door is unlocked; the low level signal usually represents a logical "0" or "false" state, representing a logic or data state opposite to the high level signal, for example, the door is locked. In this way, using high and low level signals to represent the door lock opening signal can simplify the transmission and processing process of the above signal.

[0067] In the embodiment of the present application, the door lock opening signal includes at least one of a door lock full lock signal, an external handle electrolytic signal, and an electronic hand-clip electrolytic signal. The door lock full lock signal refers to a signal that all door locks of the vehicle are in a locked state, which can be triggered by touching the door lock full lock switch and received by the vehicle's control unit to perform further safety or convenience functions, such as triggering an alarm system, automatic car locking function, etc. The door lock full lock switch is usually located above the inside of the car window; the external handle electrolytic signal usually refers to the capacitive sensor signal on the outside door handle, which can detect the user's approach and touch, thereby triggering the unlocking of the vehicle; the electronic hand-clip electrolytic signal is a signal triggered by touching or pulling the electronic hand-clip in the car, which can trigger operations such as door unlocking and window lowering after being received by the vehicle's control unit.

[0068] In some embodiments, the door opening associated signal can be received through a communication line. Specifically, after the door opening associated signal is triggered, the signal is sent to a vehicle controller, such as a body controller, through a communication line. The communication line includes a communication bus inside the vehicle, such as a controller area network bus, a local interconnect network bus, etc., which is used for information transmission between various components inside the vehicle. Through these communication buses, the door opening associated signal can be quickly and accurately transmitted from the trigger source to the vehicle's door lock control system, thereby achieving precise control of the door status.

[0069] In the embodiment of the present application, the door opening associated signal may be a signal sent by the vehicle controller through the communication line, which includes at least one of a door opening request signal and a vehicle unlocking signal. The door opening request signal refers to a signal that the user intends to open the door through a corresponding operation. For example, the user sends a request to open the door by operating a remote control, a physical button, a virtual button on a display screen, and a virtual button on a mobile device, and the request is processed by the vehicle controller to trigger the door opening request signal; the vehicle unlocking signal refers to a signal that triggers the unlocking of all vehicle doors, which can be triggered by the user's related operations, the automatic decision of the vehicle system, etc. For example, the user operation can be triggered by the user triggering the corresponding button, and the automatic decision can be that when the vehicle decelerates to a certain value, the vehicle stops completely, or the vehicle is turned off, the system will automatically generate a vehicle unlocking signal to unlock the vehicle, and at the same time, for hidden door handles, the door handles can be unfolded for subsequent operations.

[0070] In the embodiment of the present application, when at least one of the vehicle's door lock unlocking signal and the door opening associated signal is received, the window can be controlled to drop according to the above signal to ensure that when the user opens the door, the window can be automatically adjusted to a suitable position. Such a setting can ensure that no matter which signal the user triggers, the vehicle can quickly respond and control the window to drop, thereby improving the convenience and safety of riding. The process is as follows Figure 2As shown, the following steps are included:

[0071] Step 201: Generate a lifting motor control signal based on at least one of a door lock unlocking signal and a door opening associated signal of a vehicle;

[0072] This step is to generate a lifting motor control signal according to the above signal after receiving at least one of the vehicle's door lock opening signal and the door opening associated signal. Specifically, after receiving at least one of the vehicle's door lock opening signal and the door opening associated signal, the vehicle system will perform logical judgment based on these received signals and generate corresponding lifting motor control signals accordingly. The lifting motor is the actuator of the automatic door and window lifter, which is used to execute the driver's or passenger's instructions and drive the window glass to perform lifting operations. For example, after receiving the door opening associated signal, it is judged. If it is in the door opening state, a control signal will be generated to control the lifting motor to complete the preparation work before the vehicle door opening request.

[0073] Step 202: Send a lift motor control signal to the window lift motor, so that the lift motor drives the window to go down.

[0074] Based on step 201, the generated lifting motor control signal is sent to the window lifting motor. After receiving the control signal, the window lifting motor drives the window to lower. For example, the generated lifting motor control signal is sent to the window lifting motor through the communication bus to drive the frameless window to lower to a suitable position. The pin diagram of the window lifting motor is shown in FIG. Figure 3As shown, the door lock full lock signal is a hard-wired wake-up pin, which is acquired through high and low levels. When the door lock signal jumps to a low level, it is effective, triggering door unlocking; the external handle electrolytic signal and the electronic buckle electrolytic signal are both non-hard-wired wake-up pins, which are acquired through high and low levels. When the external handle and the electronic buckle are pulled or touched, they jump from a high level to a low level, triggering door unlocking. In the embodiment of the present application, before controlling the window to be lowered according to at least one of the received vehicle door lock opening signal and door opening associated signal, the current state of the window needs to be judged. If the window is in a closed state, or the difference between the window and the closed state is within a preset distance range, the window lowering operation is performed; if the window is judged to be in an open state, or the difference between the window and the closed state exceeds the preset distance range, no operation is performed, so that the user's needs can be responded to more accurately and intelligently, so as to perform subsequent window lowering operations. The above-mentioned preset distance range is used to ensure that when the user opens the car door, the window drops down smoothly and will not be worn. Its value can be determined according to the width of the car body sealing strip. For example, a certain safety margin is added to the width value of the car body sealing strip. For different types of vehicles, the value of the preset distance range is also different; the closed state is when the upper edge of the window reaches the top stop point, where the top stop point is pre-set. The top stop point position of the window varies depending on the model of frameless door vehicles.

[0075] In the embodiment of the present application, the purpose of controlling the window to be lowered can be achieved by controlling the upper edge of the window to be lowered to the lower soft stop point. Specifically, a control signal is generated based on at least one of the received vehicle door lock opening signal and the door opening associated signal, and the control signal is sent to the lifting motor, thereby driving the window to be lowered to a suitable position, namely, the lower soft stop point. After the window reaches the lower soft stop point, the lifting function of the lifting motor will be shielded, and it can no longer control the window to rise. This setting can effectively avoid the accidental lifting of the window due to misoperation or other reasons, and further improve the convenience and safety of riding. The above-mentioned lower soft stop point refers to a specific position, which can ensure the normal opening of the door, and will not cause damage to the door or body sealing strip, nor cause air leakage. It can be determined based on the upper stop point position and the preset distance range. For example, if the preset distance range is 10mm-25mm, the position of the lower soft stop point is within the range of 10mm-25mm from the upper stop point, and includes the position of the boundary point of the preset range.

[0076] In the embodiment of the present application, the distance between the top dead point and the lower soft stop point is set to the above-mentioned preset distance range. For example, if the preset distance range is 10mm-25mm, the distance between the top dead point and the lower soft stop point is 10mm-25mm.

[0077] In some embodiments, when controlling the lowering of the vehicle windows based on at least one of the received vehicle door lock opening signals and door opening associated signals, specifically, any one of the received door lock opening signals, door opening request signals and vehicle unlocking signals can be used to control the lowering of the vehicle windows, and after the window lowering operation is completed based on any one of the above signals, the window lowering will no longer be controlled when the other two signals are received. This arrangement can provide users with more options. Even if one of the signals cannot be received, other signals can be used to control the lowering of the vehicle windows, thereby enabling the windows to be lowered smoothly while effectively reducing the wear on the windows when the vehicle doors are opened. For example, the process of controlling the lowering of the vehicle windows based on the door lock opening signal is as follows: Figure 4 As shown, the following steps are included:

[0078] Step 401, start controlling the window of the frameless door:

[0079] When the user approaches the vehicle or is inside the vehicle with the intention of opening the door, it indicates that it is necessary to start controlling the windows of the frameless doors.

[0080] Step 402, determining whether the vehicle window is in a closed state or the distance between the vehicle window and the closed state is within a preset distance range;

[0081] Based on step 401, the user needs to determine whether the window is in a closed state or the window is within a preset distance from the closed state. If it is determined that the window is in a closed state or the window is within a preset distance from the closed state, step 403 is executed, otherwise, step 404 is executed. When the above user determines the current state of the window, there are two situations: first, the user outside the vehicle can determine whether the window is closed or the window is within a preset distance from the closed state by observation or mobile device query; second, the user inside the vehicle can determine whether the window is closed or the window is within a preset distance from the closed state by observation, mobile device query, and viewing the information displayed on the vehicle display screen.

[0082] Step 403, start the window lift motor;

[0083] In the above step 402, when it is determined that the window is in the closed state or the window is within a preset distance range from the closed state, the window lift motor is turned on. If the user is outside the vehicle, the window lift motor is turned on after the vehicle is powered on.

[0084] Step 404: do not perform any operation;

[0085] In the above step 402, if it is determined that the window is in the open state, or the window is beyond the preset distance range from the closed state, no operation is performed. For example, when the preset distance is 18 mm, and the upper edge of the window is 18 mm below the top dead center or exceeds 18 mm, that is, the lower soft stop point, the window lift motor no longer performs any operation.

[0086] Step 405: determine whether a door lock opening signal is received;

[0087] In step 403, after starting the upgrade motor, it is also necessary to determine whether the hardware circuit receives a door lock opening signal, such as a door lock full lock signal, an external handle electrolysis signal, and an electronic handle electrolysis signal, etc. If it is determined that the hardware circuit receives a door lock opening signal, execute step 406, otherwise, execute step 407.

[0088] Step 406, controlling the vehicle window to descend;

[0089] In the above step 405, after determining that the hardware circuit receives the door lock opening signal, a lifting motor control signal is generated according to the above signal, and the signal is sent to the window lifting motor, so that the lifting motor drives the frameless window to descend to a suitable position, such as a lower soft stop point.

[0090] Step 407: Do not perform any operation.

[0091] In the above step 405, after determining that the hardware circuit has not received the door lock opening signal, the window lift motor does not perform any operation.

[0092] In some embodiments, the window can be controlled to be lowered according to the received door lock opening signal and vehicle unlocking signal. Specifically, Figure 5 As shown, the following steps are included:

[0093] Step 501: upon receiving a vehicle door lock opening signal, determining whether a vehicle unlocking signal is received;

[0094] This step is to detect whether the vehicle unlocking signal is also received when the vehicle door lock opening signal is received. If it is determined that the vehicle unlocking signal is received, the window lifting motor is used to complete the corresponding operation, otherwise, the window lifting motor will no longer perform any operation.

[0095] Step 502: When it is determined that the vehicle unlocking signal is received, control the vehicle window to be lowered.

[0096] On the basis of step 501, after determining that the vehicle unlocking signal is received, the window is further controlled to be lowered. Specifically, according to the received vehicle door lock opening signal and vehicle unlocking signal, when it is judged that it indicates the door opening state, a corresponding lifting control signal is generated, and the above control signal is sent to the window lifting motor to drive it to descend, that is, to descend to a suitable position. In this way, according to the above two signals, the window is jointly controlled to descend, which can effectively prevent the child user from accidentally triggering the door lock opening signal or the vehicle unlocking signal due to the mistaken touch of the door lock full lock switch, the external handle electrolytic switch and other components, thereby avoiding the potential safety hazards caused by the window descent. The above vehicle unlocking signal may be received before the door lock opening signal, and after receiving the door lock opening signal, it is detected whether the vehicle unlocking signal has been received, and then the window is controlled to descend according to the above received signal. For example, before receiving the door lock opening signal 105ms, the vehicle unlocking signal has been received, and after receiving the door lock opening signal, it is detected whether the vehicle unlocking signal exists, and if so, the window is controlled to descend to a suitable position.

[0097] In some implementations, as described above, if it is set that after receiving the door lock opening signal, for example, after receiving at least one of the above-mentioned door lock full lock signal, the outside handle electrolysis signal and the electronic handle electrolysis signal, it is also necessary to determine whether the whole vehicle unlocking signal is received before the vehicle can be controlled to descend slightly; in some special cases, for example, it can be determined that the communication line fails, such as when the above-mentioned LIN signal line fails and the whole vehicle unlocking signal cannot be received, the window can be controlled to descend directly according to the above-mentioned door lock opening signal.

[0098] Figure 6 A structural schematic diagram of a window control system for a frameless door provided in an embodiment of the present application, the system includes a window controller 61 and a window lift motor 62. The above-mentioned window controller 61 is used to receive a door lock opening signal and a door opening associated signal of the vehicle, and when receiving at least one of the door lock opening signal and the door opening associated signal of the vehicle, control the window lift motor 62 to drive the above-mentioned window to descend. Specifically, when the window controller receives at least one of the door lock opening signal and the door opening associated signal of the vehicle, these signals are immediately judged. If it is determined to be a door opening signal, a corresponding lift motor control signal is generated to control the window lift motor 62 to work and drive the window to descend to a suitable position, that is, the lower soft stop point.

[0099] As described above, controlling the lowering of the windows of frameless doors through the system can not only simplify the operation of opening the vehicle doors for users, but also improve the accuracy and stability of the lowering of the windows of frameless doors, thereby effectively reducing the wear and tear of the windows while greatly improving the overall user experience.

[0100] In some embodiments, the window control system of the frameless door further includes a door lock sensor 63, such as Figure 7 As shown. The door lock sensor 63 is connected to the window controller 61 through a hardware circuit, and is used to send a door lock opening signal to the window controller 61 through the hardware circuit. Through the use of the door lock sensor, the vehicle system can more sensitively and accurately capture the door lock opening action triggered by the user, so as to respond and execute the corresponding window control operation in time. The hardware circuit is a physical path for transmitting signals or data, which can be used to connect the door lock device with the vehicle control system to realize signal transmission, including a physical path composed of wires, cables and other transmission media that directly connect the door lock and the vehicle control system.

[0101] In some embodiments, the window control system of the frameless door further includes a vehicle controller 64, such as Figure 8 As shown. The vehicle controller 64 is connected to the window controller 61 via a communication line, and is used to send a door opening related signal to the window controller 61 via the communication line. Through the use of the vehicle controller, the vehicle system can more intelligently control the opening and closing of the window according to the overall state of the vehicle and the needs of the user, thereby providing a more personalized and convenient driving experience. The communication line includes a communication bus inside the vehicle, such as a controller area network bus, a local interconnect network bus, etc., which is used for information transmission between various components inside the vehicle.

[0102] In the embodiment of the present application, the above-mentioned vehicle adopts a partition control architecture. When controlling the window of the frameless door of the vehicle, it is necessary to use the vehicle controller, window lifting motor and window controller of the corresponding area according to the partition situation to complete the window lowering operation. Fig. 9 The figure is a schematic diagram of a window control system for a frameless door. For example, when the left front window needs to be controlled to be lowered, the user needs to first touch the door lock full lock switch, the outside handle, the electronic buckle and other components, and then the door lock sensor 1 collects any one of the door lock opening signals such as the door lock full lock signal, the outside handle electrolytic signal and the electronic buckle electrolytic signal, or the left front window switch signal, and then sends the above signals to the left front window controller through the hardware circuit respectively. The left front window controller generates a corresponding lifting motor control signal based on the received signal to control the left front window lifting motor to drive the window to descend to a suitable position.

[0103] The present application also provides a control method for a frameless vehicle door. Fig.10 A flow chart of a control method for a frameless vehicle door provided in an embodiment of the present application is shown in FIG. Fig.10 As shown, the following steps are included:

[0104] Step 1001: When it is determined that the window of the frameless door reaches a preset position after being lowered, respond to a door lock unlocking signal and a door opening request signal to control the frameless door to open.

[0105] In the embodiment of the present application, in response to at least one of the door lock opening signal and the door opening request signal, it is automatically determined whether the window of the frameless door has dropped to a preset position, and when it has dropped to the preset position, the frameless door can be controlled to open in response to the door lock opening signal and the door opening request signal. This technical solution can realize the linkage between the automatic drop of the window to the preset position and the door opening signal, and the above-mentioned door opening information can refer to the door lock opening signal and the door opening request signal; thus, the window can be controlled to drop without manual operation, and the frameless door can be automatically opened, and it is ensured that the body sealing strip or the door will not be damaged.

[0106] The technical solution provided by the embodiment of the present application supports multiple door opening signals. For example, the door lock opening signal refers to an electrical signal that triggers the unlocking of the vehicle door lock, which can be triggered by factors such as vehicle keys, remote control operations, sensor detection inside the vehicle, and the vehicle's automatic decision-making system. For example, when the vehicle's security system or smart entry system recognizes that an authorized key or card is close to the vehicle, it will automatically trigger the door lock opening signal; the door opening request signal refers to a signal that the user intends to open the door through corresponding operations. For example, the user issues a request to open the door by operating a remote control, a physical button, a virtual button on a display screen, and a virtual button on a mobile device. The request is processed by the vehicle controller and triggers the door opening request signal. In this way, in response to multiple door opening signals, the frameless door can be more intelligently controlled to open, thereby improving the convenience of users using the vehicle.

[0107] In the embodiment of the present application, the position of the upper edge of the window of the frameless door can be used to determine whether the window of the frameless door has reached the preset position after being lowered. Specifically, it is determined whether the upper edge of the window of the frameless door has dropped to the lower soft stop point. If the upper edge of the window drops to the lower soft stop point, it is determined that the window of the frameless door has reached the preset position after being lowered. At this time, the frameless door is controlled to open based on at least one of the received vehicle door lock opening signal and the door opening request signal; otherwise, the window of the frameless door is controlled to continue to drop based on at least one of the received vehicle door lock opening signal and the door opening request signal. When it drops to the preset position, the frameless door is controlled to open according to the above signal. In this way, when the window drops to the appropriate position, the frameless door can be directly controlled to open, which can effectively avoid the risk of collision caused by improper window position, thereby improving the overall user experience. The above-mentioned preset position is the location of the lower soft stop point, which can ensure that the door opens normally without causing damage to the door or body sealing strips, or causing air leakage. As mentioned above, this method can more intelligently control the frameless door, which can improve the convenience and comfort of users using the vehicle, so that users can enjoy a more considerate and personalized service experience while enjoying the convenience of technology.

[0108] In the embodiment of the present application, the window of the frameless door can be controlled to be lowered so as to reach a preset position after being lowered. Specifically, the window of the frameless door can be controlled to be lowered to a preset position according to at least one of the door lock opening signal and the door opening request signal received from the vehicle, and then the opening action is further performed in response to at least one of the door lock opening signal and the door opening request signal of the vehicle, which is equivalent to realizing two controls of the window lowering and the door opening with one door opening signal. For example, after receiving the door opening request signal of the vehicle, the signal is immediately judged, and after determining that it is a door opening signal, a corresponding lifting motor control signal is generated and sent to the window lifting motor to control the window to be lowered and lowered to a suitable position, that is, a lower soft stop point, which can be determined according to the upper dead center position and a preset distance range. After the window lowering operation is completed according to any one of the above signals, the window is no longer controlled to be lowered when other signals are received. For example, when a door lock opening signal is received, the lowering operation of the vehicle with frameless doors is completed based on it. If a door opening request signal is also received 100ms after receiving the door lock opening signal, at this time, the window is no longer controlled to descend to the appropriate position based on the door opening request signal.

[0109] In some embodiments, in addition to being able to control the frameless door to descend based on at least one of the received vehicle door lock opening signal and door opening request signal, the frameless door can also be controlled to descend to a preset position based on the window pre-adjustment signal. The above-mentioned window pre-adjustment signal is a vehicle unlocking signal, which refers to a signal that triggers the unlocking of all vehicle doors. It can be triggered by relevant user operations, automatic decision-making of the vehicle system, etc. For example, when the vehicle decelerates to a certain value, the vehicle stops completely, or the vehicle is turned off, the system will automatically generate a vehicle unlocking signal to unlock the vehicle for subsequent operations. That is, when any one of the door lock opening signal, the door opening request signal, and the vehicle unlocking signal is received, the window can be controlled to descend, and after any one of the above signals completes the window descending operation, if other signals are received, the window will no longer be controlled to descend. For example, when a door opening request signal is received, the descending operation of the vehicle with frameless doors is completed according to it. If the vehicle unlocking signal is also received 100ms after the door opening request signal is received, at this time, the window will no longer be controlled to descend to a suitable position, that is, the preset position, according to the vehicle unlocking signal.
