Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to a trunk retrieval system and method. Background Technology

[0002] When users carry heavy items to the trunk, they need to manually open the trunk to place them, which is difficult and inconvenient. Some related technologies use a drive motor to power a lifting and rotating mechanism to move the luggage tray upwards and outwards, assisting users in retrieving items. This method requires the user to lift the items to a certain height and place them on the luggage tray, which has drawbacks when the user cannot reach heavy items. Another approach involves a tailgate sensor area to trigger an action that adjusts the air suspension height for easier item retrieval. However, this patent requires the user to lift the items to a certain height and also requires air suspension, making it less universally applicable. Yet another method involves pulling a skateboard out of the car, placing heavy items on it, and then using a motor to pull the skateboard into the trunk. This patent occupies trunk space and requires manual operation, making the process cumbersome. Summary of the Invention

[0003] One objective of this invention is to provide a tailgate-assisted extraction system to solve the problem of fully automated handling of heavy objects without user operation, and which is integrated with the tailgate and does not occupy the internal space of the tailgate; another objective is to provide a tailgate-assisted extraction method; and a third objective is to provide a vehicle.

The in-vehicle surround view module is located at the front of the vehicle, while the rear and sides are equipped with surround view cameras for real-time human body capture and user image acquisition. The in-vehicle control module is connected to the in-vehicle surround view module and can receive user images sent by the in-vehicle surround view module, determining user behavior based on the user images. User behavior recognition can be based on an image recognition model to identify the user behavior. Different control signals are issued based on different user behaviors. These control signals can include control signals for the trunk-assisted module to move items, or control signals for the trunk-assisted module to extend. The trunk-assisted module is connected parallel to the vehicle trunk and to the in-vehicle control module. The trunk-assisted module can receive control signals sent by the in-vehicle control module and, based on these control signals, detach from the vehicle trunk to automatically move items; or, based on these control signals, extend for the user to ride in.

The cargo trolley 4, controlled by the main control box 3, automatically transports items when it leaves the vehicle's tailgate.

[0068] Furthermore, the tail box auxiliary module also includes: a cargo trolley storage box 5, which is connected to the main control box 3 and the cargo trolley 4, and is used to replenish the power of the cargo trolley 4.

[0069] In this embodiment of the invention, the tailgate auxiliary module further includes a cargo trolley storage box 5. That is, the tailgate auxiliary module comprises a support plate 1, a robotic arm 2, a main control box 3, a cargo trolley storage box 5, and a cargo trolley 4. The cargo trolley storage box 5 connects to the cargo trolley 4 during its auxiliary operation to provide power. If the cargo trolley 4 is electrically driven, the cargo trolley storage box 5 charges it. The cargo trolley storage box 5 can receive signals from the main control box 3 and then unfold. The cargo trolley storage box 5 can unfold in various ways, such as unfolding two sides to form a ramp, or unfolding only one side, through the hidden surface within this side, automatically unfolding under gravity via guide rails on both sides to form a ramp leading to the ground. This invention uses unfolding two sides as an example. The cargo trolley 4 proceeds to the ground via this ramp.

Various identification methods can be used, such as cameras, infrared, and radar. A preferred embodiment of the invention uses a camera. The power unit 7 can provide various power sources to drive the other units. In an optional embodiment, it is driven by a motor. The control unit 9 is connected to the power unit 7 and the identification unit 6, providing positioning, planning, and decision-making functions. It receives the user's real-time location from the vehicle system, determines the relative position of the trolley and the user, controls the trolley to travel along the planned route to the user's location, and receives signals from the identification unit 6 to control the power unit 7, making decisions on problems encountered during the trolley's movement, such as road obstacles and pedestrian avoidance. The energy unit 8 is connected to the power unit 7, providing various energy sources. A preferred example of the invention is a power supply. The conveying unit 10 is connected to the power unit 7, carries the items, and transports them from the trolley 4 to the support plate 1.

The lighting units 12 are distributed around the trolley 4 and connected to the control unit 9. In dark scenes such as night, they illuminate the trolley's path to inform the user of its location. When the weight of an object placed on the trolley 4 exceeds its carrying capacity, a red light or other warning color is emitted to alert the user. The sound unit 13 emits an audible warning when the weight of an item placed on the trolley 4 exceeds a preset threshold.

[0080] In an optional embodiment of the invention, the vehicle control module includes:

[0081] The vehicle infotainment unit is connected to the vehicle surround view module and is used to determine user behavior based on the user image;

[0082] The body control unit, connected to the vehicle infotainment unit and the trunk auxiliary module, is used to generate and send the control signal based on the user's behavior.

[0083] In this embodiment of the invention, the vehicle control module includes a vehicle infotainment unit and a body control unit. The vehicle infotainment unit is connected to the vehicle surround view module, receives user images collected by the vehicle surround view module, identifies the user images, and determines whether the user is carrying a heavy object. The input terminal of the body control unit is connected to the vehicle infotainment unit, and the output terminal of the body control unit is connected to the trunk assistance module. Based on user behavior, it generates and sends control signals to control the trunk assistance extraction device.

[0084] In an optional embodiment of the present invention, the trunk-assisted extraction system further includes:

[0085] The cloud module, connected to the vehicle control module and the vehicle surround view module, is used to upload the user behavior and the corresponding user image to the cloud.

[0086] In this embodiment of the invention, the trunk-assisted extraction system further includes a cloud module, which can connect to the cloud via OTA (Over-The-Air) technology.

[0090] This invention allows users to automatically transport objects into the trunk; through OTA updates, it continuously optimizes user behavior and the basic model, making the trunk assistance device more intelligent and intuitive. It can also provide a resting area for users in the back of their vehicles.

[0091] Reference Figure 7 The diagram illustrates a flowchart of an embodiment of a trunk-assisted extraction method according to the present invention. This embodiment discloses a trunk-assisted extraction method applied to the trunk-assisted extraction system described above, the method comprising:

[0092] Step 701: When a user is detected entering a preset sensing range, the vehicle surround view module is controlled to acquire the user's image.

[0093] Step 702: Control the vehicle control module to determine the user's behavior based on the user image and issue a control signal;

[0094] Step 703: Control the tailgate auxiliary module to detach from the vehicle tailgate based on the control signal to automatically transport items; or to extend based on the control signal for the user to ride in.

[0095] In this embodiment of the invention, when a user carrying a key or a linked mobile phone / wristband / glasses or other user identification item enters the vehicle's preset sensing range, i.e., when the user is detected entering the preset sensing range, the vehicle's surround view module is controlled to acquire the user's image. After obtaining the user image, the vehicle's control module analyzes and identifies the user's behavior based on the image and issues a corresponding control signal. Based on the control signal, the trunk assistance module detaches from the vehicle's trunk to automatically transport items; or, based on the control signal, extends to allow the user to sit. The preset sensing range can be referenced... Figure 8 Once a user enters the sensing range, the system can control the vehicle as described above and record the user's driving trajectory. When the user is within a designated area, the trunk assistance module can be used for the user's ride.

[0096] For details, please refer to Figure 9 and Figure 10 This document describes the entire process of the tailgate-assisted extraction method based on the tailgate-assisted extraction system:

[0097] 1. When a user enters the vehicle's sensing range carrying a key / a mobile phone / wristband / glasses (or other items linked to the vehicle's infotainment system), the sensing range is determined by combining the vehicle's sensing range with the human body's perceptible area. The vehicle's external notification module activates, all exterior lights turn on, and a buzzer sounds at an appropriate volume to notify the user that the infotainment unit is activated. The infotainment unit then uses the current time and the vehicle's built-in light sensor to determine whether to keep the lighting on. Upon receiving the signal, the vehicle activates the infotainment unit and simultaneously turns on the surround-view camera in the surround-view module to continuously monitor the user.

[0098] 2. The vehicle infotainment unit uses a pre-installed basic model to analyze user images captured by the surround-view cameras in real time. When it detects that a user is carrying a heavy object, it transmits a start signal and the user's location to the vehicle control unit. This basic model is based on a general image recognition model. (Taking a general recognition model, transfer learning, and fusion model as an example, the model is used to train and label human movements and whether an object is being held.) Alternatively, the trunk assistance module can be remotely opened via in-vehicle interactions such as the infotainment system, in-vehicle voice commands, in-vehicle gestures, or devices linked to the vehicle infotainment unit, such as smartphones or wristbands.

[0099] 3. After receiving the signal and the user's location, the vehicle unit transmits the start signal and user's location to the trunk auxiliary extraction module through the vehicle control unit.

[0100] 4. Upon receiving a signal from the vehicle control unit, the trunk auxiliary extraction module is activated. The main control box controls the cargo trolley's storage box to open, creating a path. The cargo trolley is then started, and the main control box sends the user's location, input from the vehicle's infotainment system, to the cargo trolley. Upon receiving the user's real-time location from the main control box, the cargo trolley plans the optimal route through the control unit, activates the vehicle lighting unit to illuminate the road ahead, and informs the user of the cargo trolley's location. The cargo trolley's recognition unit collects real-time road information and feeds it back to the control unit. The control unit, combined with the real-time terrain feedback from the recognition module, performs obstacle avoidance and detour operations, bringing the cargo trolley to the optimal location near the user. This optimal location is determined by the user's perceived distance and the convenience of placing items on the cargo trolley.

[0101] 5. The surround-view camera continuously monitors the user. When the vehicle unit detects that the user has placed all items into the delivery cart or receives a weight warning signal from the conveyor unit, the delivery cart warning module emits an audible alert to remind the user that the cart has reached its maximum load capacity and should wait for reloading upon return. The vehicle unit then sends a return signal from the delivery cart to the vehicle control unit.

[0102] 6. The vehicle body control unit transmits the signal to the auxiliary extraction module, which controls the delivery trolley to return. The main control box records the initial position of the support plate and simultaneously controls the unfolding of the robotic arm to place the support plate in a position that makes it easy for the delivery trolley to place the goods on the support plate.

[0103] 7. After the delivery trolley receives the return signal, the control unit receives the return position input by the vehicle unit. This position is based on the unfolded position of the support plate. The control unit plans the optimal route, and the recognition module collects road information in real time to perform obstacle avoidance, detour and other operations.

[0104] 8. After the vehicle unit detects that the delivery trolley has arrived at the designated location, the vehicle unit sends a signal to the body control unit.

[0105] 9. The vehicle body control unit transmits a signal to the tail box auxiliary extraction module, which then activates the conveying unit on the cargo trolley to transport the object onto the support plate.

[0106] 10. The vehicle unit determines whether there is an object on the support plate. When the vehicle unit detects that the object is already on the support plate, it sends a signal to start the auxiliary extraction device robotic arm and moves the delivery trolley to a position that avoids the influence range of the robotic arm, and transmits the signal to the vehicle control unit.

[0107] 11. The vehicle body control unit transmits a signal to the tailgate auxiliary extraction module. The main control box of the tailgate auxiliary extraction module controls the delivery trolley to move to a range where it is not interfered with by the robotic arm. The robotic arm rises and the support plate returns to its initial position, aligning with the vehicle's tailgate, and the object is delivered into the tailgate.

[0108] 12. When the vehicle system detects that there are no objects to be moved in the user's hands / around them, it will send a signal to the vehicle control unit to turn off the trunk retrieval module.

[0109] 13. The body control unit sends a signal to the tail box auxiliary extraction module. The main control box of the tail box auxiliary extraction module controls the delivery trolley to return to the delivery trolley storage box for recharging, and the delivery trolley storage box is closed.

[0110] 14. The vehicle-mounted surround-view camera continuously monitors the vehicle. Initially, when the vehicle's infotainment unit detects a user leaving the sensing area or entering the vehicle, it sends a signal to the vehicle control unit. Later, the user's movement trajectory collected by the surround-view camera is used as a probabilistic movement trajectory. Once a certain number of probabilistic movement trajectories have been collected, the probabilistic movement trajectory collection is complete. When the vehicle's infotainment unit detects a user moving away from the vehicle or entering the vehicle, it combines the current user's movement trajectory with the probabilistic movement trajectory to make a judgment. If the probability of the user moving away exceeds a certain value, it is determined that the surround-view camera and vehicle infotainment unit need to be turned off. Alternatively, if the user leaves the sensing area, it is determined that the trunk auxiliary extraction module needs to be turned off. When it is determined that the surround-view camera and vehicle infotainment unit need to be used, the vehicle infotainment unit sends a signal to the vehicle control unit. If the probability of the user entering the vehicle exceeds a certain value, it is determined that the task ends, and the vehicle infotainment unit and surround-view camera remain on. (Example: Determining if the user is moving away.)

[0111] 15. The vehicle control unit controls the buzzer to emit an appropriate sound to alert the user that the vehicle is about to be locked. Then the vehicle infotainment system locks and the surround-view camera turns off.

[0112] 16. When a user wants to rest, they can open the support panel to a preset position through in-vehicle interactions such as the vehicle's infotainment system, voice commands, and gestures, as well as through devices linked to the vehicle's infotainment system like smartphones and wristbands. The support panel can also be adjusted to the user's desired height via stepless adjustment via smartphones / vehicle infotainment systems. Later, the system collects the user's movement trajectory using surround-view cameras as probabilistic movement trajectories. Once a certain number of probabilistic movement trajectories are collected, the system completes the probabilistic movement trajectory collection. Later, it combines time and spatial dimensions to comprehensively judge the user's movement trajectory. For example, if a user has a habit of sitting on the support panel to rest at a certain time / location, even if the user does not move according to the probabilistic movement trajectory, it is judged that the support panel should be opened. The system combines the current user's movement trajectory with the probabilistic movement trajectory for judgment. If the probability that the user intends to sit on the support panel to rest is greater than A, the support panel is opened. If the user has a habit of opening the support panel at a certain time / location, the probability is weighted, and if the probability that the tailgate is opened is greater than A, it is also judged that the support panel should be opened. When the probability of the trunk retrieval device being opened is greater than A, the vehicle system sends a signal to the vehicle control unit.

[0113] 17. The body control unit transmits a signal to the trunk assistance extraction module. After receiving the signal from the body control module, the trunk assistance extraction module opens the support plate to the set position.

[0114] 18. Initially, users can disable the trunk retrieval assist device via in-vehicle interactions such as the vehicle infotainment system, voice commands, and gestures, as well as through devices linked to the vehicle's infotainment system, such as smartphones and smartwatches. Later, user movement trajectories collected by surround-view cameras will be used as probabilistic movement trajectories. Once a certain number of probabilistic movement trajectories have been collected, probabilistic movement trajectory collection is complete. When the vehicle infotainment system detects that the user's movement trajectory is moving away from the vehicle, the vehicle unit combines the current user's movement trajectory with the probabilistic movement trajectory to make a judgment. If the probability of the user moving away exceeds a certain value, it is determined that the trunk retrieval assist module needs to be disabled. Alternatively, it is determined that the trunk retrieval assist module needs to be disabled when the user leaves the sensing area. When it is determined that the trunk retrieval assist device needs to be disabled, the vehicle unit sends a signal to the body controller.

[0115] 19. The body control unit sends a signal to the tailgate auxiliary extraction module. Upon receiving the signal from the body control unit, the tailgate auxiliary extraction module resets the support plate to its initial position, and the tailgate closes. The body control unit then controls the buzzer to emit an appropriate sound to alert the user that the door is about to be locked. The vehicle infotainment system then locks, and the surround-view cameras are turned off.

[0116] 20. After the surround-view cameras cease continuous monitoring, the vehicle-mounted unit uploads the user's movement trajectory to the cloud via a cloud module. When the number of user movement trajectories exceeds a certain value, the initial probabilistic movement trajectory collection is completed. This data is then combined with a general prediction model's spatial and temporal dimensions to predict and judge the user's movement trajectory. For example, if the user has a habit of carrying things or resting on a support platform at a certain time / location, a comprehensive judgment is made based on the alignment rate between the current user's movement trajectory and the probabilistic movement trajectory. This predicts the user's next destination and intention, fitting a basic model. The model is then used to train and calibrate the user's behavior when the delivery cart stops beside them. For example, if the user moves or turns around when the delivery cart stops, the model adjusts the delivery cart's position to match the user's habits. The model also trains and calibrates the position of the support platform needed when the user rests. For example, if the model recognizes that the user frequently adjusts to a certain height, the support platform of the auxiliary extraction module can be automatically opened to the user's desired height based on the user's movement trajectory. By continuously uploading videos to the cloud through the vehicle's infotainment system, the basic model and user behavior are continuously iterated and optimized. Furthermore, based on the cloud module, the data is distributed to the vehicle's infotainment system via OTA, making the trunk assistance extraction module more adaptable to user habits.
