For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

According to the embodiments of the present invention, there is provided a method, apparatus, electronic device, and storage medium for controlling a tail gate of a vehicle, it being noted that the steps shown in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that herein.

Fig. 1 shows a flow chart of an embodiment of a control method of a vehicle tailgate of the invention. As shown in fig. 1, the method comprises the steps of:

step S11, detecting a first action of a user in a preset sensing area of a target vehicle.

In the embodiment of the application, after the target vehicle is electrified, for example, a user takes a key to be electrified near the vehicle to sense or swipe a card to electrify or a mechanical button to electrify, each sensor and the projection lamp are electrified to be in a waiting working state, wherein the sensor detects a preset sensing area to detect whether the user generates a first action in the preset sensing area, the first action can be a foot kicking action or a leg lifting action, and the sensor can be an infrared sensor.

Step S12, projecting a projection pattern to a specified area according to the first action.

In an embodiment of the application, the kick sensor transmits a signal of the detected first action to the controller. After receiving the signal of the first action, the controller determines to execute the projection action, namely, the projector projects a projection pattern to a specified area. The designated area may be a ground area corresponding to a projector, where the projector is connected to a device (e.g., a computer or a storage device) storing the projected pattern, and is configured to project the desired pattern. The projection pattern can be text, image, video and other contents, and the user can set according to actual requirements.

Step S13, detecting a second action of the user on the projection pattern.

After sensor commissioning is completed, a threshold value needs to be set to determine the action of the user stepping on. The threshold may be set according to actual requirements, for example, when it is detected that the intensity of the infrared light received by the receiver exceeds a certain set value, it is determined that the user performs a second action, and the second action may be a stepping action or a foot sliding action.

Monitoring a second action: once the sensor is activated and the threshold is set, it will continuously monitor the second action of the user on the projected pattern. When the user steps on, the infrared sensor receives the reflected infrared light and judges whether the user performs a second action according to a preset threshold value.

Triggering corresponding actions: when the infrared sensor detects the second action of the user, the corresponding action may be triggered by a corresponding program or device. For example, a corresponding change in the projected pattern may be triggered by a computer program coupled to the projection system, or other actions may be triggered by means coupled to other devices, such as emitting a sound or a light change, etc.

Step S14, a tailgate control instruction is generated based on the second action, and the vehicle tailgate of the target vehicle is controlled to open or close according to the control instruction.

In the embodiment of the application, corresponding tail gate control instructions are generated according to the output of the sensor and the set threshold value. This may be achieved by a control system or embedded device to which the sensor is connected. For example, depending on the duration and intensity of the second action, a control instruction is generated to control whether the tailgate is opened or closed. And (3) controlling a tail gate: and transmitting the generated tail gate control instruction to a control system of the target vehicle. The vehicle control system controls the opening or closing of the tailgate accordingly, depending on the content of the control command. This may be achieved by means of a connection to a vehicle control system, such as via an on-board network or wireless communication, etc.

Fig. 2 shows a flow chart of an embodiment of a control method of a vehicle tailgate of the invention. As shown in fig. 2, the method comprises the steps of:

Step S21, detecting a first action of a user in a preset sensing area of the target vehicle.

In the embodiment of the application, as shown in fig. 3, a projection lamp 1, an audio device 2, an infrared sensor 3 and a light sensor 4 are installed at a vehicle tail gate of a target vehicle, and the projection lamp is used for projecting different patterns to realize prompt of a sensing area. The infrared sensor is used for sensing a first action of a user at the tail gate. The light sensor is used for sensing the illuminance of the environment, and the subsequent controller can adjust the brightness of the projection lamp according to the illumination intensity. The audio device is used for outputting audio of different rhythms according to the speed of the user stepping on the pattern.

Specifically, a first action generated by a user in a preset sensing area is detected through an infrared sensor. The infrared sensor is composed of a transmitter and a receiver. The transmitter emits an infrared signal and the receiver receives the reflected infrared signal. A preset sensing area is created at the bottom or side of the tail gate of the vehicle, which may be a specific area range set to meet sensing requirements, and the infrared sensor is triggered and receives the reflected infrared signal only when the foot of the user enters the area. That is, when the user's foot enters the predetermined sensing area, a portion of the infrared signal is reflected by the foot back to the sensor's receiver. Resulting in a change in the infrared signal received by the receiver. The infrared sensor transmits the received infrared signals to the controller for processing. The controller analyzes the change of the signal and determines whether a user performs a first action. When the controller confirms that the user has performed the first action, the projection may be triggered.

Step S22, projecting a projection pattern to a specified area according to the first action.

In an embodiment of the present application, before projecting the projection pattern to the specified area according to the first action, the method further includes: acquiring the current geographic position of a target vehicle; acquiring landmark information or scenic spot information associated with a geographic position; a projection pattern is generated based on landmark information or sight spot information.

Specifically, a pre-established landmark or scenic spot database is first determined, wherein the landmark or scenic spot database contains landmark or scenic spot information of each geographic location. Such information may include names, descriptions, pictures, etc. During the projection process, the controller first removes the current geographic location of the overhead target vehicle from the positioning system. Next, the controller matches the current geographic location of the vehicle with a landmark or sight spot database to determine the landmark or sight spot currently in place. Based on the matched landmark or sight spot information, the controller may generate a corresponding projection pattern. The pattern may be an actual picture of a landmark, a display of a name, a related graphic, or a design of other creative.

As one example, the target vehicle mounts a GPS device, and acquires its geographic location in real-time. The GPS device acquires longitude and latitude coordinates of the target vehicle through satellite signals. The acquired longitude and latitude coordinates are converted into specific geographic position information, such as cities, streets, buildings and the like, through geographic position analysis service. And inquiring by using the geographic position of the target vehicle based on the landmark information or the scenic spot information database to acquire landmark information or scenic spot information related to the current position of the target vehicle. Querying surrounding landmark information may include: business centers, restaurants, parks, museums, shopping centers, etc.; querying surrounding sight information may include: points of interest, scenic spots, amusement parks, etc. And determining corresponding projection patterns according to the landmark information or the scenic spot information. For example, images, marks, names, and other elements of landmarks or scenery spots are combined to generate a theme-compliant projection pattern.

In an embodiment of the present application, before projecting the projection pattern to the specified area according to the first action, the method further includes: acquiring interest preference of a user; projection images associated with interest preferences are obtained from a pattern library.

Specifically, interest preference of the user can be obtained according to the interaction mode between the vehicle and the user. For example: the user expresses information such as favorites, interests, preferences and the like by touching the interactive interface or voice commands and the like. Interest preferences may include user preferences for particular subject matter, color, shape, style, or pattern types. The data may be recorded in digital or textual form for subsequent processing and analysis. The collected user interest preference data is then used to construct an interest preference model. Machine learning algorithms or data mining techniques may be used to analyze the user data to identify interesting features and preference patterns of the user. This can help to learn the preferences of the user and predict the projected images that they may like. A library of patterns is also created containing projected images associated with user interest preferences. Images matching the user preferences are selected and collected from a pattern library according to the user's interest preference model. The pattern library may contain various image resources such as pictures, illustrations, graphics, and the like.

When determining to perform the projection action, the user's interest features may be matched with the projection images in the pattern library according to the user's interest preference model. And selecting a projection image which is most suitable for the interest preference of the user according to the matching result.

In an embodiment of the present application, projecting a projection pattern to a specified area according to a first action includes the following steps A1 to A3:

and A1, detecting the illumination intensity of the environment where the target vehicle is located.

In the embodiment of the application, the illumination intensity can be detected by the light sensor. Specifically, the light sensor may sense light in the environment and convert it into an electrical signal. The electrical signal converted by the light sensor is transmitted to the controller for processing. The controller may calculate the value of the illumination intensity from the received electrical signal.

And step A2, determining a target brightness value matched with the illumination intensity.

In the embodiment of the application, the target brightness value corresponding to the measured illumination intensity is determined according to the mapping relation between the preset illumination intensity and the brightness value. For example: the mapping relation between illumination intensity and brightness value can be that illumination intensity is high, then projection lamp control module control projection lamp illuminance is higher, if illumination intensity is low, then projection lamp control module control projection lamp illuminance reduces, and the purpose can be in order to let the projection pattern clear, can reach the purpose of saving the energy again. The controller then adjusts the brightness of the projection lamp of the target vehicle based on the target brightness value. For example: the change in brightness can be achieved by adjusting the current of the lamp or the PWM signal.

And A3, controlling a projection lamp of the target vehicle to project a projection pattern to a specified area according to the target brightness value.

In the embodiment of the application, the controller transmits the projection pattern to the projection lamp after adjusting the brightness of the projection lamp to the target brightness value, and the projection lamp projects the projection pattern to the appointed area according to the target brightness value. The designated area may be a projection range of a projection lamp default setting.

Specifically, the projection lamp for controlling the target vehicle projects a projection pattern to a specified area according to a target brightness value, including: determining a preset projection area based on the designated area; detecting whether a target object affecting user treading exists in a preset projection area; if the target object exists in the preset projection area, scanning other areas without the target object in the ground, and determining a target projection area meeting the projection pattern from the other areas; and controlling the projection lamp to project a projection pattern to the target projection area according to the target brightness value. And if no target object exists in the preset projection area, projecting a projection pattern in the preset projection area.

Wherein, the preset projection area is determined based on the specified area, and the preset projection area may be an area directly under the projection lamp. A suitable sensor is used to detect the presence or absence of objects, such as water accumulation, snow accumulation, etc., within the predetermined projected area. For example: and acquiring a ground image through a camera. And using the trained recognition model to recognize the ground image, and determining whether a target object such as accumulated water, snow and the like exists in the preset projection area.

If the target object exists in the preset projection area, whether the user is influenced by the treading of the user can be judged according to the size, the height or other characteristics of the target object. If the object affects the user's stepping, it is necessary to scan other areas of the ground that are not affected by the object. The status of other areas may be detected and recorded by a motion sensor or scanning device. According to the scanning result, selecting a ground area which meets the requirement of the projection pattern and is not influenced by the target object as a target projection area. And then adjusting the brightness of the projection lamp according to the brightness requirement of the target projection area. It is possible to ensure that the projected pattern is clearly visible in the target projection area by controlling the brightness parameters of the projection device or the projection lamp. The selected projection pattern is projected toward the target projection area by controlling the projection device.

The method provided by the embodiment of the application detects whether the target object influencing the treading of the user exists in the preset projection area, so that the user can be ensured not to be unnecessarily blocked or injured when treading the projection pattern, and the use safety is improved. And if the preset projection area has an object, determining the object projection area meeting the projection pattern by scanning other ground areas. Thus, the problem that the complete pattern cannot be projected due to interference of the target object can be avoided. And meanwhile, according to the brightness requirement of the target projection area, controlling the projection lamp to project a projection pattern according to the target brightness value. This may ensure that the projected pattern is clearly visible, improving the user experience and visual effect.

In the embodiment of the application, the method further comprises the following steps: if the other areas do not have the target projection area meeting the projection pattern, acquiring environment data of the target vehicle; determining a wall closest to a tail gate of the vehicle based on the environmental data; and controlling the projection lamp to project a projection pattern to the wall body according to the target brightness value.

Specifically, if the other area does not have the target projection area satisfying the projection pattern, the environmental data in which the target vehicle is located may be acquired. By acquiring the environmental data of the target vehicle, the information of the surrounding environment, such as objects, walls, etc., can be acquired. Based on the environmental data, a wall closest to the tail gate of the target vehicle may be determined. And controlling the projection lamp to project a projection pattern to the wall body according to the target brightness value. By adjusting the brightness of the projection lamp, it is ensured that the projected pattern is clearly visible on the wall.

According to the method provided by the embodiment of the application, under the condition that other areas cannot meet the projection pattern, the nearest wall body is selected as the projection area according to the environmental data of the target vehicle, so that the projected pattern is ensured to be complete, clear and visible. This may provide a better user experience and ensure an efficient presentation of the projected pattern.

Step S23, detecting a second action of the user on the projection pattern.

In the embodiment of the application, the vehicle tail gate side of the target vehicle is provided with the camera so as to completely capture the area of the projection pattern and the second action of the user. The second motion may be a stepping motion, capturing an image through the camera, and then processing the image captured by the camera using computer vision techniques. Including background modeling, target detection and tracking, etc. algorithms to extract and identify projected pattern areas and user foot motions from the images.

Through the results of the image processing, a model may be trained to recognize the second action of the user using machine learning or deep learning methods. This may be matched and classified with a predefined second action by extracting key features such as the position, trajectory, shape, etc. of the foot. When the second action of the user is identified and classified, a corresponding control may be triggered.

Step S24, a tail gate control command is generated based on the second action, and the opening or closing of the vehicle tail gate of the target vehicle is controlled according to the control command.

In the embodiment of the application, a corresponding tail gate control instruction is generated according to the second action. For example, when the user finishes stepping, an instruction to open the tail gate is generated, or an instruction to close the tail gate is generated. And sending the generated control instruction to a tail gate of the vehicle. After receiving the control command, the vehicle tail gate executes corresponding actions, namely opening or closing, according to the command.

In an embodiment of the present application, after detecting the second action on the projection pattern, the method further comprises: detecting the execution speed corresponding to the second action; acquiring audio data corresponding to the execution speed; the audio device of the target vehicle is controlled to play the audio data.

Specifically, the second motion of the user is monitored by a sensor or a camera, etc., and the movement speed of the foot is measured. The speed of execution of the user may be calculated using motion capture techniques or calculating the change in displacement of an object in an image between successive frames. Corresponding audio data is set according to the execution speed of the user. A set of audio data may be predefined and classified or matched according to different execution speeds. For example: the execution speed of the user is judged by calculating the time length of the second action. If the time length is shorter, the second action is faster; if the length of time is longer, it is indicated that the second action is slower. And selecting different music to play according to the execution speed of the user. A set of fast-paced and slow-paced music may be prepared in advance. When the execution speed is high, selecting fast-paced music to play; when the execution speed is slow, music with a slow tempo is selected for play.

And transmitting the audio data corresponding to the execution speed to the audio equipment of the target vehicle by connecting with the audio equipment of the target vehicle. The audio data may be transmitted to the audio device of the target vehicle using wireless transmission techniques, such as bluetooth or Wi-Fi, or using a wired connection. The audio device of the target vehicle receives the audio data and decodes and plays the audio data so that the user can hear the audio matching the execution speed thereof.

According to the method provided by the embodiment of the application, the audio data corresponding to the execution speed is obtained by detecting the execution speed corresponding to the second action, and the audio data is controlled to be played by the audio equipment of the target vehicle, so that an interactive system for playing the audio according to the execution speed of the user can be realized. Such a system may provide an audio experience that matches the user's actions, enhancing the interaction and entertainment of the user. The specific implementation mode can be adjusted according to the application scene and the requirement.
