[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] In the description of the present invention, it should be noted that the terms "top", "bottom", "up", "down", "left", "right", "front", "back", "inside", "outside", etc. used to indicate directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the position or component referred to must have a specific direction, a specific structure and operation, and therefore cannot be understood as a limitation on the present invention.

[0030] In the related art, for a car of the same model, the window switches corresponding to different doors use the same hardware structure, and in order to meet the different functions of the windows of different doors, the window switches corresponding to different doors have different built-in window control strategies (e.g., the window of the front passenger door has functions such as comfortable window raising, while the windows of the left rear door and the right rear door do not have functions such as comfortable window raising, then the window switch of the front passenger door also has a comfortable window raising control strategy, and the anti-pinch control strategies corresponding to the anti-pinch functions of the windows of the front passenger door, the left rear door or the right rear door are different), that is, by changing the built-in window control strategies of the window switches, the functional requirements of the windows of different doors are adapted. For example, the window switch corresponding to the right rear door has a built-in window control strategy corresponding to the function of the right rear door. However, the appearance of the window switches of different doors is the same, only the window control strategies are different, which has the risk of easy confusion in assembly and high management costs.

[0031] Based on the above problems, the inventors have discovered through research that a position identification terminal can be set on the control unit body of the window switch control unit. When configuring the window switch, the position identification terminal can be connected to the wiring harness corresponding to the door or not connected to the wiring harness, so that it can be configured to be powered, grounded or suspended. Then, the control unit body can call the window control strategy corresponding to the configuration of the position identification terminal according to the configuration of the position identification terminal, and then control the lifting and lowering of the windows of the corresponding doors, thereby realizing universal interchangeability of window switches during assembly, reducing confusion of window switches during assembly, and reducing management costs.

[0032] Figure 1 Schematic diagram of the structure of a window switch control unit provided by an embodiment of the present application. Figure 1 As shown, the window switch control unit includes a control unit body 10 .

[0033] The control unit body 10 has an input terminal 11, an output terminal 12 and a position identification terminal 13. The position identification terminal 13 is configured to be connected to electricity, grounded or suspended.

[0034] Here, the window switch control unit can be arranged on a circuit board, the circuit board can be arranged in the window switch, and the window switch can be installed at any position of the door, which can be determined according to actual conditions, such as being installed below the window.

[0035] Exemplarily, when the position identification terminal 13 is connected to a live wire harness, it is configured to be powered; or, when the position identification terminal 13 is connected to a grounded wire harness, it is configured to be grounded; or, when the position identification terminal 13 is not connected to a wire harness, it is configured to be suspended.

[0036] In this embodiment, the live wire harness can be any live wire harness, such as a power line, a signal line or a communication line, and the live wire harness can be a live wire harness of a door, or a live wire harness of a window switch where a window switch control unit is located. The ground wire harness is a ground wire, which can be a ground wire of a door, or a ground wire of a window switch where a window switch control unit is located. In this way, there is no need to re-set new components, saving costs.

[0037] Optionally, different doors correspond to different wiring harnesses. For example, taking the front passenger door, left rear door and right rear door as examples, the front passenger door may correspond to a live wiring harness, the left rear door may correspond to a ground wiring harness, and the right rear door may correspond to neither a live wiring harness nor a ground wiring harness. When the window switch is installed, the position identification terminal 13 of the window switch control unit is connected to the wiring harness corresponding to the door where it is located, that is, the position identification terminal 13 is connected to different wiring harnesses or is not connected to the wiring harness, and can be configured to different states. Table 1 shows the correspondence between the doors and the wiring harnesses. Of course, in actual applications, the correspondence between the doors and the wiring harnesses can also be other correspondences, without specific limitation.

[0038] Table 1

[0039] Car door Wiring Harness Passenger car door Wiring harness Left rear door Ground harness Right rear door /

[0040] Optionally, the control unit body 10 may be a microcontroller unit (MCU). The MCU may detect the state of the position identification terminal 13. In addition, the MCU has built-in window control strategies for all windows, such as window control strategies corresponding to the front passenger door, window control strategies corresponding to the left rear door, and window control strategies corresponding to the right rear door. The window control strategies include anti-pinch control strategies, variable speed lifting and lowering control strategies, automatic window opening and closing control strategies, and comfortable window lifting control strategies. And the window control strategies corresponding to different doors may be the same or different. Since the window control strategies correspond to the functions of the windows of the doors, when the functions of the windows of the front passenger door, the left rear door, and the right rear door are different, the corresponding window control strategies are also different. For example, as mentioned above, the anti-pinch control strategies corresponding to the front passenger door, the left rear door, and the right rear door are different, or the window of the front passenger door also has a comfortable window opening function (corresponding to a comfortable window lifting control strategy), while the left rear door and the right rear door do not have a comfortable window opening function (not corresponding to a comfortable window lifting control strategy).

[0041] In this embodiment, the MCU also has a built-in mapping relationship between the state of the position identification terminal and the window control strategy. As mentioned above, the above mapping relationship can be that the power connection corresponds to the window control strategy of the front passenger door, the ground connection corresponds to the window control strategy of the left rear door, and the suspension corresponds to the window control strategy of the right rear door. In this way, after the MCU detects the state of the position identification terminal 13, it can directly find the window control strategy corresponding to the state from the stored information, and then call the corresponding window control strategy to achieve the correspondence between the window control strategy of the window switch control unit and the door where the window switch control unit is located.

[0042] For example, in actual applications, when the window switch is to be installed on the front passenger door, the front passenger door corresponds to the live wire harness. The user can take any window switch and connect the position identification terminal 13 of the MCU to the live wire harness of the front passenger door or the window switch itself. In this way, the position identification terminal 13 is configured to be powered. After the MCU detects that the position identification terminal 13 is powered, it directly calls the built-in window control strategy corresponding to the front passenger door according to the mapping relationship between the state of the built-in position identification terminal and the window control strategy, thereby realizing the correspondence between the window control strategy and the door. The MCU can control the window of the front passenger door according to the window control strategy corresponding to the front passenger door.

[0043] Alternatively, when the window switch is to be installed on the left rear door, the left rear door corresponds to the grounding harness. The user can take any window switch and connect the position identification terminal 13 of the MCU to the grounding harness of the left rear door or the window switch itself. In this way, the position identification terminal 13 is configured to be grounded. After the MCU detects that the position identification terminal 13 is grounded, it directly calls the built-in window control strategy corresponding to the left rear door according to the mapping relationship between the state of the built-in position identification terminal and the window control strategy, thereby realizing the correspondence between the window control strategy and the door. The MCU can control the window of the left rear door according to the window control strategy corresponding to the left rear door.

[0044] Alternatively, when the window switch is to be assembled on the right rear door, the right rear door does not correspond to the live wire harness and the ground wire harness. The user can take any window switch and disconnect the position identification terminal 13 of the MCU from the wire harness. In this way, the position identification terminal 13 is configured to be suspended. After the MCU detects that the position identification terminal 13 is suspended, it directly calls the built-in window control strategy corresponding to the right rear door according to the mapping relationship between the state of the built-in position identification terminal and the window control strategy, thereby realizing the correspondence between the window control strategy and the door. The MCU can control the window of the right rear door according to the window control strategy corresponding to the right rear door.

[0045] For example, refer to Figure 2After the window switch is assembled, the control unit body can be initialized, and then the control unit body detects whether the state of the position identification terminal is connected to the power supply. If it is connected to the power supply, the control unit body calls the window control strategy corresponding to the front passenger door. Otherwise, the control unit body detects whether the state of the position identification terminal is grounded. If it is grounded, the control unit body calls the window control strategy corresponding to the left rear door. Otherwise, the control unit body calls the window control strategy corresponding to the right rear door.

[0046] In this way, when assembling the window switch, you only need to connect the position identification end of the MCU in the window switch to the wiring harness corresponding to the corresponding door to achieve universal interchangeability of the window switch during assembly, thereby solving the problem that the window switches corresponding to different doors have the same appearance but different window control strategies, which is easy to confuse during assembly and has high management costs.

[0047] Optionally, in this embodiment, the control unit body 10 also has a communication terminal for connecting to the vehicle controller. The vehicle controller sends the environmental information inside and outside the vehicle to the control unit body 10 of the window switch through the above communication terminal. The control unit body 10 can realize the functions of comfortable window raising or automatic window raising in rainy days based on the received environmental information and the comfortable window raising control strategy or the automatic window opening and closing control strategy.

[0048] Figure 3 Schematic diagram of the connection of a circuit board provided in one embodiment of the present application. Figure 3 As shown, the circuit board includes a switch action acquisition unit 20, a window motor control unit 30 and a window switch control unit.

[0049] The window switch control unit may be any window switch control unit in any embodiment of the present application, including a control unit body 10 having an input terminal 11 , an output terminal 12 and a position identification terminal 13 .

[0050] Exemplarily, one end of the switch action acquisition unit 20 is connected to the input end 11, and the other end of the switch action acquisition unit 20 is connected to the ground wire.

[0051] Optionally, the window motor control unit 30 includes two contactors, the current input end of each contactor is respectively connected to the power line and the ground line, the current output end of each contactor is connected to the window motor, and the coil control end of each contactor is respectively connected to the output end 12 and the power line.

[0052] The two contactors can respectively control the forward and reverse rotation of the window motor, so that the window motor can rotate forward or reverse to control the rise or fall of the window. Figure 3 In this embodiment, the ground line is represented by GND and the power line is represented by +B.

[0053] In this embodiment, the switch action acquisition unit 20 corresponds to the switch button of the window switch. For example, when the switch button is pulled up, the switch action acquisition unit 20 acquires the pulled-up switch action signal and sends the pulled-up switch action signal to the control unit body 10 through the input terminal 11. Therefore, the control unit body 10 sends the motor control signal to the corresponding contactor of the window motor control unit 30 through the output terminal 12 based on the pulled-up switch action signal and the corresponding window control strategy. The corresponding contactor in the window motor control unit 30 is turned on after receiving the motor control signal through the coil control terminal, thereby realizing the control of the window motor to rotate forward, and then controlling the window to rise.

[0054] Exemplarily, as mentioned above, the control unit body 10 also has a communication terminal 14 for connecting to the vehicle controller, and the switch action acquisition unit 20 can also collect a one-key lifting signal, and send the one-key lifting signal to the control unit body 10 through the input terminal 11. Thus, the control unit body 10 sends the corresponding one-key lifting request signal to the vehicle controller through the communication terminal 14 according to the one-key lifting signal, so that the vehicle controller sends a window lifting command to all window switches of the vehicle through the communication terminal according to the one-key lifting request signal, and each window switch controls the lifting of the window according to the received window lifting command.

[0055] In addition, as mentioned above, the vehicle controller can also send environmental information inside and outside the vehicle to the control unit body 10 of the window switch through the above-mentioned communication terminal 14, so that the control unit body 10 can realize functions such as comfortable window raising or automatic window raising in rainy days based on comfortable window raising control strategy or automatic window opening and closing control strategy according to the received environmental information.

[0056] An embodiment of the present application also provides a vehicle window switch, comprising a housing, a switch button and a circuit board.

[0057] The circuit board is arranged in the housing, the switch button corresponds to the switch action acquisition unit, and the switch button is at least partially located outside the housing. The circuit board can be the circuit board in any embodiment of the present application.

[0058] Exemplarily, in this embodiment, the switch action acquisition unit acquires the corresponding switch action signal according to the action of the switch button. For example, when the switch button is pulled up, the switch action acquisition unit acquires the pulled-up switch action signal.

[0059] The implementation process and principle of the circuit board part in the embodiment of the present application can be referred to the aforementioned embodiment and will not be repeated here.

[0060] An embodiment of the present application also provides a vehicle, comprising at least one door with a lifting window and a window switch.

[0061] The window switch can be any window switch in any embodiment of the present application. The window switch can be installed at any position of the door, for example, below the window of the door.

[0063] The position identification end of the first window switch is connected to the live wire harness of the first door, so that the position identification end of the first window switch is configured to be powered; and / or, the position identification end of the second window switch is connected to the ground wire harness of the second door, so that the position identification end of the second window switch is configured to be grounded; and / or, the position identification end of the third window switch is not connected to the wire harness of the third door, so that the position identification end of the third window switch is configured to be suspended.

[0064] In this embodiment, as mentioned above, the live wire harness can be any live wire harness, such as a power line, a signal line or a communication line, and the live wire harness can be a live wire harness of a door or a live wire harness of a window switch. The ground wire harness is a ground wire, which can be a ground wire of a door or a ground wire of a window switch.

[0065] When assembling the window switches, you can take any window switch and connect the position identification end of the window switch to the wiring harness corresponding to the door, or when the door does not correspond to the wiring harness, the position identification end of the window switch is not connected to any wiring harness, so as to achieve universal interchangeability of the window switches during assembly, and solve the problem that the window switches corresponding to different doors in the vehicle have the same appearance but different window control strategies, which is easy to be confused during assembly and has high management costs.
