Detailed Implementation

[0019] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0020] The following description, with reference to the accompanying drawings, illustrates an embodiment of a vehicle tailgate system and control method. Addressing the limitations of the aforementioned related technologies, such as the single adjustment mode, poor environmental adaptability, low structural reliability, and lack of performance recovery in vehicle tailgate systems, this application provides a vehicle tailgate system. In this system, a sensing component perceives current environmental information, user height data, and the height of the cargo to be loaded. A control component receives user commands and determines the tailgate opening command based on at least one of these factors. Finally, an execution component determines the opening mode, opening angle, and opening speed based on the determined opening command to open the tailgate. This solves the problems of the single adjustment mode, poor environmental adaptability, low structural reliability, and lack of performance recovery in related technologies. By integrating user height, obstacle distance, and weather data, dynamic decision-making for the vehicle tailgate is achieved, thereby improving cloud-based data closed-loop management and enhancing user interaction experience.

[0021] Specifically, Figure 1 This is a block diagram of a car tailgate system provided in an embodiment of this application.

[0022] like Figure 1 As shown, the car tailgate system 10 includes: a sensing component 100, a control component 200, and an execution component 300.

[0023] The sensing component 100 is used to sense the current environmental information, user height data, and the height of the object to be loaded; the control component 200 is used to receive the user's instruction information and determine the opening instruction of the vehicle tailgate based on at least one of the current environmental information, user height data, the height of the object to be loaded, and the instruction information; the execution component 300 is used to determine the opening mode, opening angle, and opening speed according to the opening instruction, and open the vehicle tailgate according to the opening mode, opening angle, and opening speed.

[0024] According to one embodiment of this application, the above-described vehicle tailgate system 10 further includes: an energy recovery component, used to switch the drive motor to a power generation mode when the closing speed of the vehicle tailgate is greater than a preset speed, and to convert the reverse electromotive force of the drive motor into DC power of a preset voltage and store it in the vehicle battery.

[0025] According to one embodiment of this application, the execution component 300 includes: an electric strut for driving the vehicle tailgate to flip or slide when the opening mode is a flip mode or a sliding mode; a side-opening motor for driving the vehicle tailgate to flip in a preset direction when the opening mode is a side-opening mode; and an electromagnetic lock for switching the locking state of the sliding track and the flipping hinge through magnetic positioning to realize the sliding, flipping, or side-opening of the vehicle tailgate.

[0026] The preset direction, preset speed, and preset voltage can all be selected by those skilled in the art according to actual design requirements, and are not specifically limited here.

[0027] Specifically, to address the problems existing in related technologies, such as the single opening mode of the car tailgate system, reliance on manual selection by the user, single obstacle detection (such as ultrasonic sensors), inability to dynamically adjust according to actual scenarios, lack of dynamic response to weather conditions, and energy waste caused by the kinetic energy of the car tailgate drive motor being dissipated as heat during the closing process, this application provides an environmentally perceptive multi-mode adaptive car tailgate system. This car tailgate system can perceive the surrounding environment in real time and automatically select the optimal opening mode and dynamically adjust the action parameters of the car tailgate according to the surrounding environment, thereby enabling adaptive control of the car tailgate opening.

[0028] Specifically, such as Figure 2 As shown, the car tailgate system of this application embodiment mainly consists of a sensing component 100 (sensing layer), a control component 200 (control layer), an execution component 300 (execution layer), an interaction layer, and an energy recovery component (energy layer). Each component is connected to a bus protocol through a standardized interface.

[0029] Among them, such as Figure 3As shown, the sensing component 100 is used to sense current environmental information, user height data and the height of the object to be carried, the distance to obstacles behind and the trajectory of movement. The sensing component 100 mainly includes at least one of millimeter-wave radar, rain sensor, gesture recognition camera and barometric pressure sensor. Among them, the millimeter-wave radar is the core environmental sensing device. It is installed on the top edge of the tailgate of the car, with a detection angle of 120°, a horizontal angular resolution of 1°, an effective detection distance of 0.1~5m, a detection accuracy of ±2cm, an operating frequency of 76-81GHz, supports multi-target tracking (e.g., simultaneously tracking ≥8 targets), and has dynamic... Millimeter-wave radar has the ability to filter static objects (such as curbs and walls). It transmits millimeter-wave signals modulated by sawtooth waves, receives the reflected waves from the target, calculates the frequency difference, and then calculates the target's distance and radial velocity. At the same time, it uses the micro-Doppler effect to analyze the vibration frequency characteristics of particles such as raindrops and snowflakes to help determine the precipitation type (such as rain, snow, and hail). Because raindrops are small in size and fall at a stable speed, their micro-Doppler frequency shift is 20~50Hz, and the signal is characterized by high-density scattering points and low radial velocity. On the other hand, hail is large in size and falls on irregular trajectories, with a frequency shift exceeding 50Hz and drastic fluctuations in the intensity of the reflected signal. Based on this, the millimeter-wave radar integrates a dynamic risk assessment algorithm and combines meteorological data with the movement status of obstacles to generate real-time decisions. When a moving object (such as a pedestrian or vehicle) is detected within 0.5 to 2 meters ahead and the rainfall intensity is >2.5 mm / h, the tailgate system automatically triggers a tailgate movement delay until a safe gap is reached. If the wind speed exceeds 10 m / s (combined with barometric pressure sensor data), the millimeter-wave radar assists in calculating the tailgate swing amplitude, and the electromagnetic damper dynamically adjusts the tailgate swing amplitude to limit it to within ±3 cm. In extreme scenarios, the millimeter-wave radar and the rain sensor work together to determine whether the rainfall is >5 mm / h and the wind speed is >8 m / s. The tailgate opening angle is forcibly locked to 60°, and the closing speed is increased to 0.5 m / s. In addition, the self-checking system checks the status of the drive components every time the tailgate is opened and closed. If there is an abnormality, the protection mode is triggered and a warning is pushed, thereby realizing intelligent matching of "scene-mode" and solving the problem of the single mode of traditional tailgates.

[0030] Furthermore, in this embodiment of the application, the current snowfall and current hailfall can be obtained by the sensing component 100. When the current snowfall is greater than a first preset threshold or the current hailfall is greater than a second preset threshold, the vehicle can be controlled to activate the anti-freeze mode to heat the vehicle's tailgate.

[0031] The first and second preset thresholds can be selected by those skilled in the art based on actual design requirements, or they can be obtained through a limited number of computer simulations, and are not specifically limited here.

[0032] Furthermore, such as Figure 3 and Figure 4As shown, the rain sensor in this embodiment is integrated into the inner side of the rear window glass near the root of the wiper. It has a resolution of 0.1 mm / h and a response time of <0.5 s. It is used to monitor rainfall intensity in real time and can calculate raindrop density through the principle of light refraction, outputting a 4-20mA analog current signal, which is then converted and input to the ECU (Electronic Control Unit). The rain sensor internally analyzes the change in refractive index of the water film formed after raindrops hit the glass to calculate the raindrop density and particle size distribution, outputting accurate rainfall intensity data. At the same time, the rain sensor can adopt a dynamic calibration mechanism. For example, in a static scenario (the vehicle is stationary and there is no precipitation), historical data filtering is used to eliminate false triggers caused by condensation or dirt on the windshield. In a dynamic scenario, the rainfall calculation is corrected by combining the vehicle speed signal. Its classification judgment logic is: on a sunny day (rainfall <0.5 mm / h), the maximum opening angle of the car tailgate (110°) can be maintained. In light rain (0.5~2.5mm / h), the tailgate opening angle can be reduced by 10%; in moderate rain (2.5~5.0mm / h), the tailgate opening angle can be further reduced by 20% and the closing speed increased by 15%; in heavy rain (>5.0mm / h), the tailgate opening angle can be limited to 80° and the closing speed increased by 30%. The data is transmitted to the signal processing module via a 4-20mA signal. After filtering and feature extraction, it is fused with millimeter-wave radar data to support the tailgate system's dynamic environmental adaptation decision-making and improve safety.

[0033] Furthermore, such as Figure 3 As shown, the gesture recognition camera is embedded above the license plate frame on the tailgate of the car. It is used to recognize the user's gesture trajectory, such as drawing a circle or waving, which can trigger the opening of the tailgate. It also has a built-in infrared fill light (wavelength 850nm) to support nighttime recognition.

[0034] Furthermore, such as Figure 3 As shown, a barometric pressure sensor is installed inside the tailgate cavity to monitor ambient wind speed (accuracy ±0.1 hPa) and atmospheric pressure, and to control the opening angle limit in strong wind conditions.

[0035] Furthermore, the control component 200 in this embodiment mainly includes a main control ECU and a signal processing module, used to receive user instruction information and determine the opening instruction of the vehicle tailgate based on at least one of the current environmental information, user height data, the height of the object to be loaded, and the instruction information. The main control ECU integrates dual CAN (Controller Area Network) bus interfaces, processes sensor data in real time, executes environmental perception algorithms, mode decisions, drive control, and self-test logic, and generates control instructions based on the fused data. The signal processing module can filter, amplify, and extract features from the original sensor signals. At the same time, the control component 200 is also used to store the user's tailgate opening parameters to a preset cloud (which can be selected by those skilled in the art according to actual design requirements, and is not specifically limited here).

[0036] Furthermore, the execution component 300 in this embodiment includes an electric strut, a side-opening motor, and an electromagnetic lock. The electric strut has a built-in Hall sensor that provides real-time feedback on the strut's position and is used to drive the tailgate to flip or slide when the tailgate is in either a flip or sliding mode. The side-opening motor is used to drive the tailgate to flip in a preset direction (e.g., to the right) when the tailgate is in a side-opening mode, with a maximum opening angle of 110°, facilitating the loading and unloading of large items. The electromagnetic lock is compatible with three mode switching and is used to switch the locking state of the sliding track and the flip hinge through magnetic positioning. The target mode can be selected via user commands, such as an APP, voice, or in-vehicle screen, or the optimal mode can be automatically recommended based on environmental data (height of the load, rear space), so as to achieve rapid switching of the mechanical structure between different opening modes (sliding mode, flip mode, or side-opening mode).

[0037] For example, if there is limited space behind, the sliding mode is recommended; if large items need to be loaded or unloaded, the side-opening mode is recommended; under normal circumstances, the default mode is flip mode. At the same time, the opening angle and closing speed can be dynamically adjusted according to the rainfall level.

[0038] Furthermore, the interaction layer of this application embodiment mainly includes a user interface and a preset cloud (cloud database). The user interface is the interface through which the user interacts directly with the car tailgate system. It is mainly responsible for instruction input and status feedback. Its main functions include (1) receiving multimodal instructions, such as gesture recognition, voice control, large screen or mobile APP operation; (2) real-time status feedback, displaying the current status of the car tailgate through the in-vehicle large screen or mobile APP; (3) personalized configuration management, such as storing user preferences and supporting multiple account switching. The cloud database undertakes data storage, remote service and intelligent optimization functions. That is to say, all operation data is uploaded to the cloud database for subsequent personalized recommendations and system optimization.

[0039] Furthermore, the energy recovery component in this application embodiment is used to switch the drive motor to the power generation mode when the closing speed of the vehicle tailgate is greater than a preset speed (e.g., 0.3m / s), and convert the reverse electromotive force of the drive motor into DC power of a preset voltage (e.g., 12-14V) through a full-bridge rectifier circuit and a high-precision voltage regulator module, and store it in the vehicle battery, for example, in a 12V vehicle battery.

[0040] Therefore, this application embodiment, by reusing the existing hardware architecture of millimeter-wave radar, rain sensor, and main control ECU, combined with the brake-by-wire system and cloud data closed loop, can achieve strong coupling control of braking performance and environmental conditions. Specifically, when the rain sensor detects rainfall intensity > 2.5 mm / h, the main control ECU obtains the road surface water film thickness and vehicle slip rate (wheel speed sensor feedback) in real time through frequency-modulated continuous wave millimeter-wave radar, and dynamically adjusts the braking force distribution: for example, the front axle braking force is reduced by 15%~25%, the rear axle braking force is increased by 20%, and short-term point braking is triggered to clear the water film on the brake disc, avoiding false triggering of ABS (Anti-lock Braking System); the millimeter-wave radar simultaneously detects moving obstacles, and the braking system suppresses energy recovery power to prevent motor overheating and tire slippage. Thus, by reusing existing sensing hardware and cloud data closed loop, the limitation of the traditional braking system's "single parameter response" is overcome, achieving a dynamic balance between safety and energy efficiency.

[0041] In summary, the tailgate mentioned in this embodiment uses multiple sensors to monitor the surrounding environment (such as obstacles, wind speed, and rainfall) in real time, and dynamically adjusts the tailgate opening speed, angle, and force based on the received environmental data to avoid collisions or damage caused by environmental factors. For example, when opening the tailgate in rainy weather, the tailgate angle will automatically adjust to be smaller, and when closing the tailgate, the speed will automatically increase. When an obstacle is detected, the tailgate operation will be paused and a prompt will be issued. Furthermore, the tailgate opening mode will be adjusted according to different environments. The system recommends the optimal mode based on the height of the cargo in the trunk, the user's height, and environmental data. The tailgate opening parameters used by the user will be automatically loaded into a preset cloud, optimized, and then sent to the user interface, such as the in-vehicle screen, based on the user's frequently used parameters when opening the tailgate again, for the user to select.

[0042] Based on the detailed discussion of the above embodiments, this application can achieve the following beneficial effects: (1) Strong multi-scenario adaptive capability: By integrating millimeter-wave radar, rain sensor and user data, it can intelligently match and switch between three modes: sliding, flipping and side opening, which greatly improves the convenience of use; (2) Full-dimensional environmental perception and safety redundancy: Real-time monitoring of obstacles, rainfall and wind speed, construction of environmental risk model, dynamic adjustment of opening angle and speed, effectively avoiding collisions and rainwater intrusion, and improving safety; (3) Energy recovery, energy saving and environmental protection: The kinetic energy is recovered and converted into electrical energy for storage during the tailgate closing process, which fills the gap in the industry and is in line with the energy saving trend of new energy vehicles; (4) Cloud collaboration and continuous optimization: Users upload data to the cloud, and the system can learn user habits and optimize control strategies to achieve personalized services; (5) Diverse interaction methods: Supports multimodal control such as gestures, voice, and APP, enhancing user experience.

[0043] The vehicle tailgate system according to embodiments of this application senses current environmental information, user height data, and the height of the cargo to be loaded using a sensing component. It receives user commands through a control component and determines the tailgate opening command based on at least one of these factors. Finally, the execution component determines the opening mode, opening angle, and opening speed based on the determined opening command to open the tailgate. This solves the problems of limited tailgate adjustment modes, poor environmental adaptability, low structural reliability, and lack of performance recovery in related technologies. By integrating user height, obstacle distance, and weather data, it achieves dynamic decision-making for the tailgate, thereby improving cloud-based data closed-loop management and enhancing user interaction experience.

By integrating user height, obstacle distance, and weather data, dynamic decision-making for the vehicle tailgate is achieved, thereby improving cloud-based data closed-loop management and enhancing user interaction experience.
