[0048] The specific implementation of the present application is further described below with reference to the accompanying drawings.

[0049] It is easy to understand that according to the technical solution of the present application, without changing the essential spirit of the present application, a variety of structural modes and implementation modes that can be replaced by those skilled in the art can be replaced with each other. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the present application, and should not be regarded as the entirety of the present application or as a limitation or restriction on the technical solution of the application.

[0050] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to different positions and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0051] The present application provides a wiper gear adjustment method, which is applied to a controller for controlling the wiper gear in a vehicle, such as Figure 1 As shown, including:

[0052] S10: Obtain the current working gear of the wiper.

[0053] The controller is used to control the wiper, so it can collect and monitor the working status of the wiper in real time, so it can obtain the current working gear of the wiper.

[0054] S20: Obtaining a capacitance change value sent by a capacitance sensing sensor, wherein the capacitance change value corresponds to a gear change value of the wiper; wherein the capacitance sensing sensor is arranged along the circumference of a gear ring of the wiper, and after the capacitance sensing sensor senses a touch operation, the capacitance change value corresponding to the touch operation is obtained.

[0055] The capacitive sensing sensor is arranged on the circumference of the wiper gear ring. If the driver wants to adjust the wiper gear, he slides and touches the capacitive sensing sensor with his hand. The driver's touch operation corresponds to the desired gear change value, so that the capacitance value of the capacitive sensing sensor changes. Therefore, the capacitance change value corresponds to the desired gear change value.

[0056] The controller receives the capacitance change value and can determine the gear change value expected by the driver.

[0057] S30: The current working gear is superimposed on the gear change value to obtain a target working gear of the wiper.

[0058] The superposition of the current gear and the gear change value is the target working gear.

[0059] For example, if the gear change value is positive one gear, the current working gear of the wiper is increased by one gear and used as the target working gear; if the gear change value is negative one gear, the current working gear of the wiper is reduced by one gear and used as the target working gear.

[0060] S40: Adjusting the working gear of the wiper to the target working gear.

[0061] In specific implementation, the controller can be connected to the drive motor of the wiper. After determining the target working gear, the controller determines the target rotation direction and target speed of the drive motor, and controls the drive motor to work according to the target rotation direction and the target speed to adjust the working gear of the wiper to the target working gear.

[0062] The scheme in the above embodiments of the present application receives the capacitance change value sent by the capacitive sensing sensor based on the touch operation. Since the touch operation is performed by the user based on the expected gear change value, the capacitance change value corresponds to the gear change value. Therefore, after determining the capacitance change value, the corresponding gear change value can be determined. After superimposing the current working gear with the gear change value, the target working gear can be obtained. The wiper gear adjustment can be completed by controlling the working gear of the wiper to the target working gear. The scheme of the present application automatically analyzes the target gear corresponding to the touch operation sensed by the capacitive sensing sensor, thereby eliminating the accuracy deviation of the rotation angle control operation due to different user feel, and improving the accuracy of the wiper working gear adjustment.

[0063] In some embodiments of the wiper gear adjustment method, in step S20, the process in which the capacitance change value corresponds to the wiper gear change value includes:

[0064] S201: Determine a touch direction of the touch operation corresponding to the capacitance change value.

[0065] The correspondence between the capacitance change value and the touch direction is pre-stored in the controller. For example, a larger capacitance change value corresponds to a clockwise direction, and a smaller capacitance value corresponds to a counterclockwise direction.

[0066] S202: If the touch direction is the first direction, the gear change value is a positive value, and the first direction is clockwise or counterclockwise; if the touch direction is the second direction, the gear change value is a negative value, and the second direction is opposite to the first direction.

[0067] In some schemes, after receiving the capacitance change value, the controller can determine whether the gear should be increased or decreased. Here, the capacitance change value can be set to have only one value, and one capacitance change value corresponds to one gear. In specific implementation, the following method can be adopted: when the touch direction is counterclockwise, the controller adds one gear to the current working gear of the wiper as the target working gear; when the touch direction is clockwise, the current working gear of the wiper is reduced by one as the target working gear. Through this scheme, the counterclockwise and clockwise touch operations are associated with the changes in the working gear of the wiper, so that the gear change law can be determined after the touch operation direction is identified, and the target gear can be obtained according to the current working gear and the gear change law. The recognition process of this scheme has no requirements for the accuracy of the driver's touch operation, and the determination of the target gear can be achieved as long as there is a direction of the touch operation.

[0068] In another solution, step S20 may further include:

[0069] S203: Acquire a touch angle of the touch operation corresponding to the capacitance change value.

[0070] The touch area of ​​the capacitive sensing sensor may correspond to the touch angle, and the touch area of ​​the capacitive sensing sensor may reflect the capacitance change value, and therefore, the capacitance change value corresponds to the touch angle.

[0071] S204: Acquire an expected gear change value corresponding to the touch angle.

[0072] The driver touches the capacitive sensing sensor. If he wants a larger gear change value, he will touch a larger area. If he wants a smaller gear change value, he will touch a smaller area. The touch area corresponds to the capacitance change value. Therefore, the capacitance change value can reflect the gear change value expected by the driver.

[0073] S205: Using the expected gear change value as the gear change value.

[0074] Whether the gear position should be increased or decreased is determined according to the touch direction, and the value of the gear position change is determined according to step S204, thereby determining the gear position change value.

[0075] In another embodiment, the wiper gear adjustment method, in step S20, the process in which the capacitance change value corresponds to the wiper gear change value, further includes:

[0076] S2A: Obtain the number of capacitance change values.

[0077] As mentioned above, a capacitance value can be set to correspond to a gear.

[0078] S2B: counting the capacitance change value when the touch direction is the first direction as a positive value superposition gear; counting the capacitance change value when the touch direction is the second direction as a negative value superposition gear.

[0079] Specifically, the controller counts the received capacitance value changes and the corresponding touch directions; determines the total number of times the touch direction is clockwise or the total number of times the touch direction is counterclockwise; and determines the actual touch direction and number based on the total clockwise number and the total counterclockwise number.

[0080] S2C: The positive value superimposed gear position and the negative value superimposed gear position are added to obtain the gear position change value.

[0081] For example, when the touch direction is counterclockwise, the current working gear of the wiper plus the number of touch directions is used as the target working gear; when the touch direction is clockwise, the current working gear of the wiper minus the number of touch directions is used as the target working gear. The recognition process of this solution does not require the accuracy of the driver's touch operation, and the target gear can be determined as long as the direction of the touch operation is known.

[0082] In the above scheme, it is only necessary to determine the driver's touch direction of the capacitive sensing sensor and the number of times corresponding to each touch direction. There is no requirement for the driver's touch operation. The processing method of only judging the touch direction has higher accuracy and lower requirements than the processing method of determining the touch angle. Therefore, the judgment result of the target working gear is more accurate.

[0083] In some embodiments, the method may further include: sending the target working gear of the wiper to an entertainment system display for display. By displaying the target working gear, the driver can confirm the gear adjustment result of the wiper.

[0084] like Figure 2 As shown, the embodiment of the present application provides a wiper gear adjustment device, comprising:

[0085] The information acquisition module 10 is configured to acquire the current working gear of the wiper. The information acquisition module 10 can collect and monitor the working state of the wiper in real time, so it can obtain the current working gear of the wiper.

[0086] The change value acquisition module 20 is configured to acquire the capacitance change value sent by the capacitance sensing sensor, and the capacitance change value corresponds to the gear change value of the wiper; wherein, the capacitance sensing sensor is arranged along the circumference of the wiper gear ring, and the capacitance sensing sensor obtains the capacitance change value corresponding to the touch operation after sensing the touch operation; the capacitance sensing sensor is arranged on the circumference of the wiper gear ring, and if the driver wants to adjust the wiper gear, he slides and touches the capacitance sensing sensor with his hand, and the driver's touch operation corresponds to the desired gear change value, so that the capacitance value of the capacitance sensing sensor changes, and therefore the capacitance change value corresponds to the desired gear change value.

[0087] The target gear acquisition module 30 is configured to obtain the target working gear of the wiper by superimposing the current working gear with the gear change value; the superposition of the current gear and the gear change value is the target working gear; for example, if the gear change value is positive one gear, the current working gear of the wiper is increased by one gear and used as the target working gear; if the gear change value is negative one gear, the current working gear of the wiper is reduced by one gear and used as the target working gear.

[0088] The wiper control gear 40 is configured to adjust the working gear of the wiper to the target working gear. In specific implementation, the wiper control gear 40 can be connected to the drive motor of the wiper. After the wiper control gear 40 determines the target working gear, it determines the target rotation direction and target speed of the drive motor, and controls the drive motor to work according to the target rotation direction and the target speed to adjust the working gear of the wiper to the target working gear.

[0089] The scheme in the above embodiment automatically analyzes the target gear corresponding to the touch operation sensed by the capacitive sensing sensor, thereby eliminating the accuracy deviation of the rotation angle control operation due to different user feel and improving the accuracy of the wiper working gear adjustment.

[0090] The wiper gear adjustment device described in some schemes, the change value acquisition module 20, is used to determine the touch direction of the touch operation corresponding to the capacitance change value. If the touch direction is the first direction, the gear change value is a positive value, and the first direction is clockwise or counterclockwise; if the touch direction is the second direction, the gear change value is a negative value, and the second direction is opposite to the first direction; the correspondence between the capacitance change value and the touch direction can be stored in advance. After receiving the capacitance change value, it can be determined whether the gear should be increased or decreased. Here, the capacitance change value can have only one value, and one capacitance change value corresponds to one gear. When the touch direction is counterclockwise, the current working gear of the wiper is increased by one gear as the target working gear; when the touch direction is clockwise, the current working gear of the wiper is reduced by one as the target working gear. Through this solution, counterclockwise and clockwise touch operations are associated with the change of the wiper working gear, so that the gear change rule can be determined after the touch operation direction is identified, and the target gear can be obtained according to the current working gear and the gear change rule. The recognition process of this solution has no requirements for the accuracy of the driver's touch operation. As long as there is a direction of the touch operation, the target gear can be determined. The processing method of only determining the touch direction has higher accuracy and lower requirements than the processing method of determining the touch angle. Therefore, the judgment result of the target working gear is more accurate.

[0091] In another scheme, the change value acquisition module 20 is used to obtain the touch angle of the touch operation corresponding to the capacitance change value. The expected gear change value corresponding to the touch angle is obtained. The expected gear change value is used as the gear change value. Among them, the touch area of ​​the capacitive sensing sensor can correspond to the touch angle, and the touch area of ​​the capacitive sensing sensor can reflect the capacitance change value. Therefore, the capacitance change value corresponds to the touch angle. When the driver touches the capacitive sensing sensor, he will touch a large area if he wants a large gear change value, and will touch a small area if he wants a small gear change value. The touch area corresponds to the capacitance change value, so the capacitance change value can reflect the gear change value expected by the driver. According to the touch direction, it is determined whether the gear should be increased or decreased, and according to the determined gear change value, the gear change value can be determined.

[0092] In another scheme, the change value acquisition module 20 is used to obtain the number of capacitance change values; count the capacitance change values ​​when the touch direction is the first direction as the positive value superposition gear; count the capacitance change values ​​when the touch direction is the second direction as the negative value superposition gear; add the positive value superposition gear and the negative value superposition gear to obtain the gear change value. As mentioned above, one capacitance value can be set to correspond to one gear. Specifically, the received capacitance change value and the corresponding touch direction are counted; the total number of times the touch direction is clockwise or the total number of times the touch direction is counterclockwise is determined; the actual touch direction and number are determined according to the total number of clockwise and the total number of counterclockwise. When the touch direction is counterclockwise, the current working gear of the wiper plus the number of touch directions is used as the target working gear; when the touch direction is clockwise, the current working gear of the wiper minus the number of touch directions is used as the target working gear.

[0093] In some embodiments, the device may further include a communication module: sending the target working gear of the wiper to an entertainment system display for display. By displaying the target working gear, the driver can confirm the gear adjustment result of the wiper.

[0094] An embodiment of the present application further provides a storage medium, in which program information is stored. After a computer reads the program information, the wiper gear adjustment method described in any one of the above embodiments is executed.

[0095] In some embodiments of the present invention, an electronic device is provided, such as Figure 3 As shown, it includes one or more processors 31 and a memory 32. Figure 3 A processor 31 is taken as an example. The electronic device may further include: an input device 33 and an output device 34. The processor 31, the memory 32, the input device 33 and the output device 34 may be connected via a bus or other means. Figure 3 The example of connecting through a bus is taken. The memory 32, as a non-volatile computer-readable storage medium, can be used to store non-volatile software programs, non-volatile computer executable programs and modules. The processor 31 executes various functional applications and data processing of the server by running the non-volatile software programs, instructions and modules stored in the memory 32, that is, implements the wiper gear adjustment method of the above method embodiment. The above product can execute the method provided in the embodiment of the present application, and has the functional modules and beneficial effects corresponding to the execution method. For technical details not fully described in this embodiment, please refer to the method provided in the embodiment of the present application.

[0096] The embodiment of the present application also provides a wiper gear adjustment system, comprising the electronic device described in the above embodiment, and also comprising a capacitive sensing sensor, which is arranged along the circumference of the wiper gear ring, and after the capacitive sensing sensor is touched, generates a capacitance change value corresponding to the touch operation, and sends the capacitance change value to the electronic device. Preferably, the capacitive sensing sensor includes a capacitive diaphragm distributed along the circumference of the gear ring, and after the capacitive diaphragm is touched, the capacitance value of the capacitive diaphragm changes.

[0097] like Figure 4-Figure 7 As shown, the capacitive sensing sensor 42 on the circumference of the gear ring 41 can be connected to the switch assembly 44 through a flexible flat cable 43. The capacitive sensing sensor 42 is used to sense touch operation and generate a capacitance change value corresponding to the touch operation; the capacitance change value of the capacitive sensing sensor 42 can be transmitted to the controller along the flexible flat cable 43, combined with Figure 8 As shown, the outside of the flexible flat cable 43 can be sleeved with a line sleeve 301, and the switch assembly 44 can be installed on the main circuit board 50. The main circuit board 50 can be located on the central control operation panel of the vehicle and covered by the operation panel cover 51. When the driver touches the gear ring 41, the capacitive sensing sensor 42 arranged around the gear ring 41 senses the touch operation, generates a capacitance change value corresponding to the touch operation, and outputs it to the main circuit board 50 of the switch assembly 44 through the flexible flat cable 43. After being processed by the main circuit board 50, the detected capacitance change value is sent to the front wiper switch status (FrtWiperSwSts, Front WiperSwitch Status) to the electronic device in the form of a CAN signal. The electronic device identifies the capacitance change value and determines the working gear change value corresponding to the capacitance change value to achieve the determination of the target working gear of the wiper, and controls the wiper to adjust to the target working gear.

[0098] The scheme of the present application replaces the mechanical knob structure with a touch-sensitive gear ring, automatically analyzing the target gear corresponding to the touch operation, thereby eliminating the accuracy deviation of the rotation angle control operation caused by different user feel, and improving the accuracy of the wiper working gear adjustment. In addition, in this scheme, the control circuit can be directly connected to the main circuit board 50, and the circuit and controller can be set based on the original structure, without the need to improve the vehicle structure.

[0099] As a feasible solution, the capacitive sensing sensors 42 are evenly distributed on the circumference of the gear ring 41 . After the capacitive sensing sensors 42 are touched, the capacitive sensing sensors 42 generate the capacitance change value and send it to the electronic device.

[0100] In some schemes, the capacitive sensing sensor 42 includes a capacitive diaphragm distributed along the circumference of the gear ring 41, and preferably the capacitive diaphragm is evenly distributed on the circumference of the gear ring 41. After the capacitive diaphragm is touched, the capacitance value of the capacitive diaphragm changes, and the capacitance change result of all the capacitive diaphragms in the capacitive sensing sensor 42 is used as the capacitance change value and the capacitance change value is sent to the electronic device. In this scheme, the logic of the touch operation detection of the gear ring 41 can be: the capacitive diaphragm can be evenly distributed on the circumference of the gear ring 41, and when the driver touches the gear ring 41 with his hand, the capacitive diaphragm will detect the capacitance change value, and finally the capacitance change value is output to the electronic device. The electronic device recognizes the driver's clockwise touch operation intention or counterclockwise touch operation intention according to the capacitance change value, and converts it into a CAN signal, and its signal may include: 0x0 = No pressed (none), 0x1 = Clockwise rotation (clockwise rotation), 0x2 = Counterclockwise rotation (counterclockwise rotation). The definition of the front wiper switch activation signal FrtWiperSwAte is as follows: 0x0: Off, off (initial value); 0x1: Auto Sensitivity Level 1, low sensitivity; 0x2: AutoSensitivity Level 2, high sensitivity; 0x3: Low speed, low speed; 0x4: High speed, high speed. The above gears are pre-defined, and the received capacitance change value is analyzed and counted according to the touch direction. Each time a counterclockwise rotation signal FrtWiperSwSts=0x2 is received, the front wiper switch activation signal FrtWiperSwAte is added by 1 based on the initial value (or current value) and then the current signal value is maintained, and the maximum value is 0x4. Each time a clockwise rotation signal FrtWiperSwSts=0x1 is received, the front wiper switch activation signal FrtWiperSwAte is subtracted by 1 based on the initial value (or current value) and then the current signal value is maintained, and the minimum value is 0x4. Thus, when the driver has multiple touch operations, the target gear position of the wiper can be determined according to the final touch operation result. According to this solution, only the direction of the touch operation on the gear ring needs to be identified, and the calibration process is more convenient.

[0101] Some embodiments of the present application provide a vehicle, including the wiper gear adjustment system described in the above solution. Fig. 9As shown, the wiper gear adjustment system 8 is connected to the vehicle entertainment system 80 in communication; the vehicle entertainment system 80 receives the target working gear of the wiper sent by the wiper gear adjustment system 8, controls the display 83 to display the target working gear, and controls the vehicle player 84 to play the sound corresponding to the wiper gear adjustment. Through this solution, the driver can observe the working gear of the wiper through the display 83. During the change of the working gear of the wiper, there is no need to generate mechanical noise during the rotation of the mechanical knob, which can improve the user experience. The vehicle player 84 can also be used to play the gear switching sound, and the sound can be more comfortable. In specific implementation, the user can also choose the type and rhythm of the sound to meet the user's personalized needs.

[0102] Preferably, the output end of the wiper gear adjustment system 8 is connected to the in-vehicle entertainment system 80 through the vehicle domain controller 81. The wiper gear adjustment system 8 and the vehicle domain controller 81, and the vehicle domain controller 81 and the in-vehicle entertainment system controller 80 are connected to each other through the CAN bus; the wiper gear adjustment system 8 transmits the capacitance change value to the in-vehicle entertainment system controller 80 through the vehicle domain controller 81 and the CAN bus. The in-vehicle entertainment system controller 80 is connected to the drive motor 82 of the wiper through the LIN bus, and the in-vehicle entertainment system controller 80 determines the motor target rotation direction and target speed corresponding to the target working gear, and controls the rotation direction and speed of the drive motor 82 to be the target rotation direction and the target speed.

[0103] In specific implementation, the in-vehicle entertainment system controller 80 counts the received capacitance change value (i.e., the gear state signal) FrtWiperSwSts. Each time the counterclockwise rotation signal FrtWiperSwSts=0x2 is received, the front wiper switch activation signal FrtWiperSwAte is added by 1 based on the initial value (or current value) and then the current signal value is maintained, and the maximum value is 0x4. Each time the in-vehicle entertainment system controller 80 receives the clockwise rotation signal FrtWiperSwSts=0x1, the front wiper switch activation signal FrtWiperSwAte is subtracted by 1 based on the initial value (or current value) and then the current signal value is maintained, and the minimum value is 0x4. According to the value of the front wiper switch activation signal FrtWiperSwAte, the front wiper gear adjustment state is displayed on the display 83, and a sound prompt is issued through the in-vehicle player 84. The in-vehicle entertainment system controller 80 sends the value of the signal FrtWiperSwAte to the drive motor 82 of the electronic wiper through LIN communication, and the drive motor 82 executes the gear adjustment instruction. This solution improves the operating comfort of the front windshield wiper gear adjustment, reduces the internal sub-parts of the gear adjustment switch, and has better reliability. In the vehicle of this application, the mechanical knob structure is replaced with a touch-type gear ring, and there is no mechanical gear operation sound during operation. The gear status can be displayed on the display screen of the in-vehicle entertainment system, and the sound feedback of the in-vehicle player can provide users with a more comfortable operation method.

[0104] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0105] The above are only the principles and preferred embodiments of the present application. It should be noted that, for ordinary technicians in this field, on the basis of the principles of the present application, several other modifications can be made, which should also be considered as the protection scope of the present application.
