However, using a foot-operated sensor requires adding a sensor to the bottom of the vehicle, which is costly. Furthermore, users need to lift one leg to trigger the sensor when carrying heavy objects, making the tailgate opening inconvenient. While key position sensing incurs no additional cost, it requires high key positioning accuracy, making it prone to misjudgments and impacting the user experience. Summary of the Invention

[0066] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0067] See appendix Figure 1 The method of the present invention includes:
[0068] S1. Detect the position of the remote key. If the remote key is within the preset distance threshold, activate the reversing radar controller and the reversing camera controller, and perform motion detection within the preset first time threshold respectively.
[0069] The remote control key position is detected by polling with low-frequency radio frequency signals through a key controller.
[0070] S2. When the reversing radar controller or reversing camera controller detects a preset first-stage action within a preset first time threshold, the rear turn signal is turned on by controlling the body controller.
[0071] The radar controller uses a radar probe to acquire distance feedback, determines user movement information based on the distance feedback, and compares the movement information with a preset first-stage action.
[0072] And / or,
[0073] The reversing camera controller uses a camera to detect user movements by recognizing light, and compares the user movements with preset first-stage movements.
[0074] When the reversing radar controller or reversing image controller detects a preset first-stage action within a preset first time threshold, it sends a first-stage control signal to the body controller.
[0075] When the vehicle body controller receives the first-stage control signal, it controls the turn signal to turn on and issues a warning within a preset second time threshold.
[0076] S3. After detecting the preset first-stage action, the reversing radar controller and the reversing image controller detect the preset second-stage action within a preset second time threshold.
[0077] S4. When the reversing radar controller and the reversing image controller detect a preset two-stage action within a preset second time threshold, the tailgate is opened.
[0078] Specifically, when the reversing radar controller detects a preset second-stage action within a preset second time threshold, it sends a second-stage control signal to the tailgate controller.
[0079] When the reversing camera controller detects a preset second-stage action within a preset second time threshold, it sends a second-stage control signal to the tailgate controller.
[0080] When the tailgate controller receives the two-stage control signals from the reversing radar controller and the reversing camera controller, it controls the tailgate to open.
[0081] Specifically, the reversing radar controller and the reversing image controller are calibrated, and the tailgate controller is set to open the tailgate when it receives a two-stage controller signal from either the reversing radar or the reversing image controller.
[0082] Specifically,
[0083] 1. Detect the position of the remote key, start the reversing radar controller and reversing camera controller, and perform action detection within the preset first time threshold.
[0084] The remote key position is detected by the key controller. The key controller polls the remote key via Bluetooth or low-frequency radio frequency signals to detect whether it is within a preset distance threshold. If the remote key is within the preset distance threshold, the reversing radar controller and reversing camera controller are activated to detect movement.
[0085] In this embodiment, when a user approaches the vehicle with the key, the key controller will wake up the entire vehicle and increase the remote key sensing frequency. When it detects that the user is carrying the remote key near the tailgate, the key controller sends a motion detection request to the reversing radar controller and the reversing camera controller. The reversing radar controller and the reversing camera controller are then activated to begin detecting the user's motion.
[0086] After being turned on, the reversing radar controller and reversing camera controller respectively detect the user's actions within a preset first time threshold.
[0087] II. Testing the first stage of the operation.
[0088] When the reversing radar controller or reversing camera controller detects a preset first-stage action within a preset first time threshold, the rear turn signal is activated via the body controller. If neither the reversing radar controller nor the reversing camera controller detects the preset first-stage action within the preset first time threshold, the detection is terminated and restarted when the user approaches the tailgate again.
[0089] The first-stage action is a pre-set specific movement information that users can set as needed, such as: standing in the middle behind the vehicle, taking a step to the right within 2 seconds and then returning to the original position.
[0090] 1. The reversing radar controller detects the first stage of operation.
[0091] The reversing radar controller uses several radar sensors to sense the distance between the user behind the tailgate and the radar sensors via ultrasonic waves. Based on the distance feedback from multiple radar sensors, it determines the user's movement information and compares this information with a preset first-stage action. When the detected user movement information matches the preset first-stage action, a first-stage control signal is sent to the vehicle controller.
[0092] In this embodiment, the radar probe emits ultrasonic signals and receives the reflected signals. The distance is calculated by the time difference between transmitting and receiving signals. The calculation formula is: distance = (transmit / receive time difference × speed of sound) / 2.
[0093] 2. The reversing camera controller detects the first stage of operation.
[0094] The reversing camera controller uses a camera to acquire images and detects the behavior and actions of the user behind the tailgate by recognizing light. When the detected user's action information matches a preset first-stage specific action, a first-stage control signal is sent to the body controller.
[0095] In this embodiment, the reversing camera controller uses a Convolutional Neural Network (CNN) algorithm to extract features from images captured by the camera, primarily including the extraction of features from the main joints of the human body. After feature extraction, pose regression is performed. If the pose matches a pre-defined pose, pre-set specific action information is output to estimate the human pose.
[0096] 3. The vehicle body controller activates the rear turn signal.
[0097] When the vehicle body controller receives a first-stage control signal from either the reversing radar controller or the reversing camera controller, it will activate the turn signal as a warning to prompt the user to initiate the second-stage action detection.
[0098] The rear turn signal remains in a warning state for a preset second time threshold, and then turns off; or the body controller turns off the rear turn signal after the tailgate switch state changes.
[0099] III. Testing the second phase of the action.
[0100] After detecting the preset first-stage action, the reversing radar controller and the reversing camera controller detect the preset second-stage action within the preset second time threshold.
[0101] If the reversing radar controller and reversing camera controller do not detect the second-stage action within the preset second time threshold after detecting the preset first-stage action, the detection ends and restarts when the user approaches the tailgate again.
[0102] Specific movement information can be pre-set as a specific action in the second stage, such as: taking a step to the left and returning to the original position.
[0103] The process of detecting the second-stage action of the reversing radar controller and reversing camera controller is the same as that of detecting the first-stage action, and will not be repeated here.
[0104] Fourth, when the reversing radar controller and the reversing image controller detect a preset two-stage action within a preset second time threshold, the tailgate is opened by controlling the tailgate controller.
[0105] The reversing radar controller and the reversing camera controller each detect a second-stage action within a preset second time threshold. When the reversing radar controller detects a preset second-stage action within the preset second time threshold, it sends a second-stage control signal to the tailgate controller; when the reversing camera controller detects a preset second-stage action within the preset second time threshold, it sends a second-stage control signal to the tailgate controller; upon receiving the second-stage control signals from the reversing radar controller and the reversing camera controller, the tailgate controller controls the electric tailgate actuator to open the tailgate.
[0106] In this embodiment, the reversing radar controller and the reversing camera controller can be calibrated. Depending on the calibration, the tailgate controller can also be configured to open the tailgate using the electric tailgate actuator when it receives a signal from either the reversing radar or the reversing camera controller.
[0107] In this embodiment, after fully calibrating the reversing radar controller and the reversing image controller, a specific posture and action can be set and maintained for a specific time as a first-stage action or a second-stage action.
[0108] Calibration of the reversing radar controller and reversing camera controller includes, but is not limited to, adjusting the parameters of the reversing radar controller and reversing camera controller.
[0109] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0110] See appendix Figure 2 The structure of a sensor-activated tailgate control system for implementing the above method is shown, including: a key detection module, a first-stage detection module, a second-stage detection module, and a tailgate control module.
[0111] The key detection module is used to detect the position of the remote key. If the remote key is within a preset distance threshold, the reversing radar controller and the reversing camera controller are activated, and action detection is performed within a preset first time threshold, respectively.
[0112] The first-stage detection module is used to control the rear turn signal to turn on through the body controller when the reversing radar controller or reversing image controller detects a preset first-stage action within a preset first time threshold.
[0113] The two-stage detection module is used to detect the preset two-stage action within a preset second time threshold after detecting the preset first-stage action;
[0114] The tailgate control module is used to control the tailgate to open when the reversing radar controller and the reversing camera controller detect a preset two-stage action within a preset second time threshold.
[0115] Figure 3 The schematic diagram of the sensor tailgate control component according to an embodiment of the present invention includes: a key controller 100, a remote key 101, a body controller 110, two rear turn signals 111 and 112, a tailgate controller 120, a reversing image controller 130, a camera 131, a reversing radar controller 140, and four radar probes 141, 142, 143, and 144.
[0116] In this embodiment, the key controller 100, body controller 110, reversing camera controller 130 and reversing radar controller 140 are connected via CAN bus to realize signal interaction and form a sensor tailgate control system, including but not limited to using CAN, LIN, Ethernet directly or indirectly through gateway routing.
[0117] The key controller 100 detects whether the remote key 101 is near the vehicle or tailgate, and is used to wake up the network and start the reversing radar controller 140 and the reversing camera controller 130 to detect human movement.
[0118] The radar sensors 141-144 and 140 are connected to the reversing radar controller via CAN, LIN or ordinary wiring harness to sense the distance between people behind the tailgate and the radar sensors, thereby identifying the user's movement information.
[0119] Cameras 131 and 130 are connected via a video harness to detect the behavior and actions of people behind the tailgate.
[0120] The body controller 110 is connected to the rear turn signals 111-112 via a wiring harness and is used to control the illumination of the rear turn signals.
[0121] The tailgate controller 120 is connected to the electric tailgate actuator 121 via a wiring harness. The electric tailgate actuator includes a door lock actuator and an electric strut, which is used to control the door lock actuator to unlock and the electric strut to drive in the opening direction to open the tailgate.
[0122] Figure 4 This is a schematic diagram of the control flow according to an embodiment of the present invention.
[0123] When a user approaches the vehicle with the remote key, the vehicle is awakened and the key sensing frequency is increased. The key controller determines whether the remote key is nearby: when the remote key is near the tailgate, the key controller sends an action detection request and activates the reversing radar controller and reversing camera controller to detect the user's actions; when the remote key is not near the tailgate, the vehicle remains in sleep mode.
[0124] The reversing radar controller and reversing camera controller detect whether the user has performed a first-stage action of opening the tailgate: if a first-stage action is detected, the rear turn signals will flash hazard lights as a warning; if no first-stage action is detected, it will determine whether it is within a preset first time threshold: if it is within the first time threshold, the action detection will be performed again; if it exceeds the time threshold, the vehicle will return to sleep mode.
[0125] After detecting the first-stage action, the system checks whether the user has performed a second-stage action of opening the tailgate. If the second-stage action is detected, the system opens the tailgate and exits the hazard light warning. If no second-stage action is detected, the system determines whether the action is within a preset second time threshold. If it is within the second time threshold, the action detection is performed again. If the timeout occurs, the hazard light warning is exited and the vehicle returns to sleep mode.
[0126] Furthermore, embodiments of the present invention also provide a sensor-activated tailgate control device, comprising:
[0127] The key detection module detects the position of the remote key. If the remote key is within a preset distance threshold, the reversing radar controller and reversing camera controller are activated, and action detection is performed within a preset first time threshold. The remote key position is detected by polling with low-frequency radio frequency signals through the key controller.
[0128] The first-stage detection module detects a preset first-stage action. The reversing radar controller and the reversing camera controller then detect a preset second-stage action within a preset second time threshold. When the reversing radar controller or the reversing camera controller detects a preset first-stage action within a preset first time threshold, it sends a first-stage control signal to the body controller. When the body controller receives the first-stage control signal, it activates the turn signal and issues a warning within a preset second time threshold.
[0129] The two-stage detection module detects the preset second-stage action within a preset second time threshold after detecting the preset first-stage action.
[0130] The tailgate control module controls the tailgate to open when the reversing radar controller and the reversing camera controller detect a preset second-stage action within a preset second time threshold. Specifically, when the reversing radar controller detects a preset second-stage action within the preset second time threshold, it sends a second-stage control signal to the tailgate controller. When the reversing camera controller detects a preset second-stage action within the preset second time threshold, it also sends a second-stage control signal to the tailgate controller. Upon receiving the second-stage control signals from the reversing radar controller and the reversing camera controller, the tailgate controller opens the tailgate.
[0131] Based on the same inventive concept, the present invention also provides a computer-readable storage medium storing one or more programs, which, when executed, can realize the aforementioned sensor-activated tailgate control method.
[0132] like Figure 5 As shown in the illustration, this embodiment of the invention also provides a device, including a processor, a communication interface, a memory, and a communication bus. The processor, communication interface, and memory communicate with each other via the communication bus.
[0133] The memory is a computer-readable storage medium used to store one or more programs.
[0134] The processor is configured to execute a program stored in a computer-readable storage medium.
[0135] The computer-readable storage medium may be included in the device / apparatus described in the above embodiments; or it may exist independently and not assembled into the device / apparatus.
[0136] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
