[0036] The present disclosure is further described in detail below in conjunction with the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the relevant invention are shown in the accompanying drawings.

[0037] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] Figure 1 An exemplary system architecture of an embodiment of a method for controlling a windshield wiper or an apparatus for controlling a windshield wiper disclosed in the present invention is shown.

[0039] like Figure 1 As shown, the system architecture may include a driving recorder 110, a vehicle camera 120, a vehicle display screen 130, a server 140, and a rain sensor (not shown in the drawings). The system architecture may also include an AR HUD (not shown in the drawings) and a vehicle terminal (not shown in the drawings) that establishes communication connections with the vehicle display screen and the AR HUD, respectively.

[0040] The rain sensor can detect the current rainfall.

[0041] The driving recorder 110 is used to record the video images and sounds of the entire driving process of the car.

[0042] The vehicle-mounted camera 120 can be a panoramic camera on the roof or a camera installed on each side of the vehicle body. It can capture images of the environment or the vehicle body, perform image recognition, and thus determine the rainfall. The image recognition method can also be combined with a rain sensor to determine the rainfall.

[0043] The vehicle display screen 130 can display a 3D vehicle model, which includes component models of various parts, such as a wiper component model, a window component model, a trunk component model, etc. The component component model is controllable or uncontrollable. The vehicle display screen 130 can be a touch screen for receiving touch events, and the user can interact with the 3D vehicle model through the vehicle display screen.

[0044] AR HUD is configured to project the contents of the vehicle display, that is, it can also display the 3D vehicle model. The front windshield of the vehicle can be used as a projection screen for AR HUD to display augmented reality information. Users can interact with the 3D vehicle model through gestures through AR HUD.

[0045] The vehicle terminal is configured to receive signals sent by the user through the vehicle display, microphone or button. The vehicle terminal can output the 3D vehicle model to the vehicle display or AR HUD for display for user control. For example, when the user clicks on the window component model in the 3D vehicle model, the lifting and lowering of the window can be simulated, and then mapped to the lifting and lowering control of the real window.

[0046] At present, the adjustment of wipers is usually carried out through the wiper control lever behind the steering wheel. Generally, it includes the gear adjustment of the intermittent time and the gear adjustment of the working frequency, which are basically realized through the hardware control lever. Among them, the gear adjustment of the intermittent time includes turning the wiper control lever to the intermittent gear position, and then using the knob to adjust the intermittent time; the gear adjustment of the working frequency is divided into fast and slow gears, mainly by turning the control lever to the slow or fast gear. However, in the actual driving process, the amount of rain and the speed of the vehicle will affect the working effect of the wiper. The existing gear adjustment method is relatively fixed and cannot be flexibly adjusted according to the actual needs of the driver or user.

[0047] Continue to refer Figure 2 , shows a process 200 of an embodiment of a method for controlling a windshield wiper according to the present disclosure. The method for controlling a windshield wiper comprises the following steps:

[0048] Step 201: in response to detecting first gesture information, detecting second gesture information in real time.

[0049] In this embodiment, the execution subject (e.g., the vehicle-mounted terminal) of the method for controlling the wiper can receive the user's gesture information through the vehicle-mounted display screen, wherein the first gesture information includes the user's selection operation on the predetermined wiper component model on the vehicle window in the 3D vehicle model, or in the absence of the 3D vehicle model, the user directly clicks a control button or control icon in the vehicle-mounted display screen to enter the control of the wiper. The first gesture information is used to indicate entering the manual control state of the wiper. The second gesture information includes gesture control information for the wiper component model.

[0050] Step 202: extracting gesture control information in response to detecting second gesture information.

[0051] In this embodiment, the second gesture information may include a touch slide of a finger on the vehicle display screen. The user's finger may slide back and forth on the vehicle display screen, and the sliding speed and pause interval are counted as gesture control information.

[0052] The second gesture information may also include non-contact gesture swing information of a finger in front of the vehicle-mounted display screen. The in-vehicle camera device may recognize the gesture action performed by the user in the air, take pictures, and recognize and count the moving speed and pause interval as gesture control information.

[0053] Step 203: acquiring a simulated swing frequency according to the gesture control information.

[0054] In this embodiment, gesture control information can be mapped to a simulated swing frequency, wherein the simulated swing frequency includes a simulated moving speed and a simulated cycle interval, wherein the simulated moving speed corresponds to the operating frequency of the wiper, the faster the simulated moving speed, the higher the operating frequency, and the simulated cycle interval corresponds to the intermittent time of the wiper.

[0055] In this embodiment, the wiper hardware supports a custom swing frequency, and the speed and interval of the finger sliding back and forth can be proportionally mapped to the simulated swing frequency. The proportional coefficient can be set by the user or the default value can be used.

[0056] Step 204, setting the actual oscillation frequency of the wiper assembly according to the simulated oscillation frequency.

[0057] In this embodiment, the actual oscillation frequency of the wiper assembly is set to the simulated oscillation frequency obtained in step 203. The wiper can oscillate at the set actual oscillation frequency.

[0058] The method provided by the above embodiment of the present disclosure calculates the desired wiper operating frequency and intermittent time through the gesture control information of the user for the wiper component model, and then sends a signal to set the actual operating frequency and intermittent time of the wiper. During actual driving, regardless of the current rainfall or vehicle speed, the wiper can be controlled to work at the frequency desired by the user, which effectively starts from the user's needs, improves the user experience, and ensures driving safety.

[0059] In some optional implementations of this embodiment, before or while detecting the second gesture information in real time, the method further includes: displaying a first simulated image, wherein the first simulated image includes an image of the wiper assembly model in a predetermined window model. The wiper assembly model can be displayed on a vehicle display or an AR HUD. The predetermined window model can be a front window or a rear window, and the user can select which window model to display. Figure 1 Shown is the wiper assembly model displayed in the front window model.

[0060] In one embodiment, in response to the first gesture information sent by the user, the first simulated image is displayed. That is, in response to the user's selection operation on the wiper assembly model on the predetermined vehicle window in the 3D vehicle model, or in the absence of the 3D vehicle model, the user directly clicks a control button or control icon on the vehicle display screen, or the user directly makes a predetermined gesture in the air, at this time, the first simulated image is displayed, which may be an enlarged image of the predetermined vehicle window, and the wiper assembly model is included in the image to indicate that the second gesture information can be received to enter the control of the wiper assembly.

[0061] In some optional implementations of this embodiment, while or after extracting the gesture control information in response to detecting the second gesture information, the method further includes: displaying a second simulated image, wherein the second simulated image is used to display a picture of the wiper assembly model swinging in a predetermined window model according to the simulated swing frequency. The second simulated image is a dynamic image, and the user can feel whether the swing frequency of the wiper is comfortable.

[0062] Optionally, the effect of rain flow can be added to the second simulated image to simulate the swing of the wiper in a real rainy environment, so that the user can more intuitively feel whether different swing frequencies are comfortable. The effect of rain flow can be simulated according to the current rainfall.

[0063] In some optional implementations of this embodiment, the gesture control information includes touch information of the user pressing and sliding the wiper assembly model in the first simulated image back and forth on the predetermined window model. As the finger slides, the wiper assembly model swings at the same speed and interval on the predetermined window model, which can make the user feel immersive, thereby reflecting the comfort of the wiper swing frequency in a real rainy scene.

[0064] In one embodiment, the gesture control information includes information of the user's hand swinging back and forth in the air. As the hand swings back and forth, the wiper assembly model swings at the same speed and interval on the predetermined vehicle window model.

[0065] In some optional implementations of this embodiment, the second gesture information includes touch information of a user pressing and sliding back and forth on a predetermined window model for a wiper assembly model in the first simulation image, and the extracting of the gesture control information in response to detecting the second gesture information includes: in response to detecting the second gesture information, obtaining sliding information in the second gesture information; obtaining a corresponding touch point set according to the sliding information, wherein the touch point set includes at least one touch point for pressing and sliding; obtaining the gesture control information according to the touch point set, wherein the gesture control information includes touch cycle data, and the touch cycle data includes a cycle number, a cycle interval, a cycle point set, and a cycle duration; a touch cycle is a cycle in which a horizontal coordinate of a touch point undergoes a back-and-forth sliding. The cycle number is the number of back-and-forth sliding. The cycle interval is the time interval between two adjacent cycles. The cycle point set is a set of touch points within a cycle. The cycle duration is the duration of a back-and-forth sliding. Since the user's finger may slide back and forth multiple times, there is no limit on the distance and the number of back-and-forth sliding for each slide.

[0066] like Figure 3 As shown, it is the trajectory of the touch point. It should be noted that Figure 3 The relationship between periodic events and time is presented, which does not represent the actual sliding area of ​​the user on the vehicle computer. In actual applications, the user's sliding back and forth operations may be limited to the same area.

[0067] exist Figure 3 In the figure, a periodic event indicates a continuous touch event from 1>2-3>4 (or 3>4>1>2);

[0068] The circle on the left indicates the interval point of periodic events (generally applicable to the periodic event sequence 1>2-3>4), which is mainly used for the calculation of wiper periodic event frequency;

[0069] The circle on the right indicates the interval point of periodic events (generally applicable to the periodic event sequence 3->4>1>2), which is mainly used for the frequency calculation of wiper periodic events;

[0070] The intra-cycle distance represents the distance calculated from the valid point set after curve fitting within a cycle;

[0071] The speed of a periodic event is the corresponding periodic distance divided by the corresponding periodic time;

[0072] Total cycle event average speed = (cycle event speed 1 + cycle event speed 2 + cycle event speed 3 + ... + cycle event speed n) / n, mainly used to set the execution speed within the wiper cycle event;

[0073] Periodic interval = (periodic event interval point time 1 + periodic event interval point time 2 + periodic event interval point time 3 + ... + periodic event interval point time n-1) / (n-1), which is mainly used to set the wiper periodic event trigger frequency.

[0074] In some optional implementations of this embodiment, acquiring the simulated swing frequency according to the gesture control information includes: acquiring the simulated swing frequency according to the touch cycle data, wherein the simulated swing frequency includes: a simulated movement speed and a simulated cycle interval.

[0075] The moving speed of a cycle can be calculated based on the moving distance of the periodic point set in each cycle and the cycle duration. Then the moving speeds of multiple cycles are averaged to obtain the simulated moving speed.

[0076] It is also necessary to set the time interval between one round trip of the wiper and the next round trip, that is, the cycle interval. Figure 3 The simulated cycle interval is obtained by calculating the average value of multiple cycle event intervals shown in .

[0077] The user may lift the finger between two cycles, and the cycle interval can be determined by detecting the time interval between the finger lifting and the next press.

[0078] In some optional implementations of the present embodiment, obtaining the simulated swing frequency according to the touch cycle data includes: in response to the touch cycle data corresponding to at least one touch cycle, obtaining the moving speed of each touch cycle; obtaining the simulated moving speed according to the moving speed of each touch cycle; and obtaining the simulated cycle interval according to the pause interval between any two adjacent touch cycles.

[0079] The user's finger can slide back and forth multiple times, and the trajectory does not need to be consistent each time. Therefore, the moving speed of each touch cycle can be calculated based on the moving distance of the touch point and the cycle length in each touch cycle. Then the moving speeds of multiple touch cycles are averaged to obtain the simulated moving speed. The average pause interval is calculated based on the pause interval between two adjacent touch cycles as the simulated cycle interval.

[0080] In some optional implementations of this embodiment, before acquiring gesture control information according to the touch point set, the method further includes: filtering out data corresponding to a touch period whose moving distance is less than a predetermined value. If the finger sliding track is too short, it may be an accidental touch by the user's finger, and the data has no reference value and can be filtered out.

[0081] In some optional implementations of the present embodiment, the displaying of the second simulated image includes: in response to the touch point set containing at least two or more touch points with different coordinates, generating and displaying the second simulated image, wherein in the second simulated image, the wiper assembly model swings in the predetermined window model according to the simulated swinging frequency, and wherein the distance that the movable end of the wiper assembly model moves along the predetermined curve is proportional to the distance that the touch point moves.

[0082] The wiper assembly model includes a movable end and a fixed end. The movable end draws a circle with the fixed end as the center, so the moving curve of the movable end is an arc. The present application does not limit the movement trajectory of the finger to an arc, it can also be a straight line, or a non-arc curve. The trajectory of the touch point does not completely match the movement curve of the movable end of the wiper, so the movement curve of the movable end is fitted according to the trajectory of the touch point. Similar to the mapping relationship between the mouse and the cursor, the movement curve of the movable end can be regarded as the cursor movement trajectory, and the movement trajectory of the touch point can be regarded as the mouse movement trajectory. Therefore, the moving distance of the movable end is proportional to the distance moved by the touch point.

[0083] In some optional implementations of this embodiment, the displaying of the second simulated image includes: displaying a simulated dynamic image of the wiper assembly model in a predetermined car window model in the rain in a head-up display device according to a set rainfall amount.

[0084] The rain effect of different rainfall amounts can be added to the second simulated image displayed on the head-up display device, and animation simulation can be performed for different rainfall amounts. The user can set different wiper swing frequencies for different rainfall amounts. For example, when the rain sensor detects that it is currently raining heavily during vehicle driving, the wiper can be made to swing at the swing frequency of heavy rain. Since the head-up display device utilizes the front window, the wiper swing seen by the user on the head-up display device can realistically simulate the wiper swing on the window, so that the user can accurately find the swing frequency that suits him or her.

[0085] In some optional implementations of this embodiment, the displaying of the second simulated image includes: displaying a simulated dynamic image of the wiper assembly model in a predetermined car window model under rain in a suspended image projected by a display device according to a set rainfall amount.

[0086] The second simulated image displayed in the suspended image projected by the display device can be added with rain effects of different rainfall amounts, and animation simulation can be performed for different rainfall amounts. Users can set different wiper swing frequencies for different rainfall amounts. For example, when the rain sensor detects that it is currently raining heavily during vehicle driving, the wipers can be made to swing at the swing frequency of heavy rain. Since the suspended image is displayed in 3D, users can more immersively experience the impact of the wiper swing frequency on comfort under different rainfall conditions, and thus set the wiper swing frequency that makes users most comfortable.

[0087] Continue to see Figure 3 , Figure 3 FIG. 1 is a schematic diagram of an application scenario of the method for controlling a windshield wiper according to this embodiment. Figure 3 In the application scenario, set the wiper oscillation frequency by following the steps below:

[0088] (1) The user can select a wiper assembly model from the 3D vehicle model list displayed on the vehicle display screen (including the front and rear windows, as long as it exists on the 3D vehicle model);

[0089] (2) The user slides positively or negatively according to his or her visual or frequency preference (there are no special requirements for the sliding amplitude and sliding area. The only concern is whether the curvature calculated based on the touch point set in each cycle meets the requirements.);

[0090] (3) Record the set of points for each sliding cycle (for example, sliding a finger in a straight line on the screen will generate a set of touch points on the system), the time of each cycle, and the number of cycles;

[0091] (4) Calculate the average distance per cycle based on the number of cycles and the corresponding point set;

[0092] (5) Calculate the average time per cycle based on the number of cycles and cycle time;

[0093] (6) Calculate the speed of each cycle based on the average distance and time of each cycle;

[0094] (7) After the user cancels the touch event, the speed per cycle is sent to the vehicle wiper controller.
