Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a method, apparatus, terminal device, and computer-readable storage medium for controlling a vehicle cargo box door. Background Technology

[0002] Currently, the cargo box cover installed at the rear of trucks can only be opened or closed manually by the driver. When the driver controls the cargo box cover to open or close, the process mainly involves the cargo box cover controller receiving signals from the vehicle body controller and external switches. Based on the received signals, the controller drives the strut to raise or lower the cargo box cover. At the same time, if the cargo box cover encounters an obstacle and generates resistance during the movement of the strut, the Hall signal feedback installed in the strut will change, causing an abnormal increase in the motor current. The controller then uses the Hall signal and the strut current signal to determine whether to activate the anti-pinch function. If the anti-pinch function is activated, the controller will control the cargo box cover to move in the opposite direction to avoid damage to fragile items inside the truck bed.

[0003] However, when using the above method to control the opening and closing of the cargo box cover, the cargo box cover may fail to close automatically when the driver is not near the truck and the weather around the truck changes, resulting in the cargo inside the vehicle getting wet. Summary of the Invention

[0004] The main objective of this invention is to provide a method, apparatus, terminal device, and computer-readable storage medium for controlling a vehicle cargo door, which enables the cargo door to automatically close when abnormal weather occurs.

[0005] To achieve the above objectives, the present invention provides a method for controlling a vehicle cargo box door, the method comprising the following steps:

[0006] The environment around the target vehicle is detected to obtain rainfall parameters, and a cargo box door control command is generated based on the rainfall parameters;

[0007] The cargo box of the target vehicle is detected according to the cargo box door control command to obtain the target opening value;

[0008] The cargo box door is controlled to close based on the target opening value and the preset minimum movement distance.

[0009] Further, the step of generating cargo box door control commands based on the rainfall parameters includes:

[0010] Obtain a preset rainfall parameter threshold, and compare the rainfall parameter with the rainfall parameter threshold to obtain a first comparison result;

[0011] When the first comparison result indicates that the rainfall parameter is greater than or equal to the rainfall parameter threshold, a cargo box door control command is generated.

[0012] Further, the step of detecting the cargo box of the target vehicle according to the cargo box door control command to obtain the target opening value includes:

[0013] The cargo box of the target vehicle is inspected to obtain the cargo height parameter of the cargo box;

[0014] The target opening value is calculated based on the cargo height parameters and the standard cargo box height parameters corresponding to the cargo box.

[0015] Furthermore, the step of controlling the cargo box door to perform a closing operation based on the target opening value and the preset minimum movement distance includes:

[0016] Obtain the preset minimum movement distance and the real-time opening value of the cargo box;

[0017] The distance difference is calculated based on the real-time opening value and the target opening value, and the cargo box door is controlled to close based on the distance difference and the minimum movement distance.

[0018] Further, the step of controlling the cargo box door to perform a closing operation based on the distance difference and the minimum movement distance includes:

[0019] The second comparison result is obtained by comparing the minimum movement distance with the distance difference.

[0020] When the second comparison result is that the distance difference is greater than or equal to the minimum movement distance, the cargo box door is controlled to perform a closing operation according to the target opening value;

[0021] When the second comparison result is that the distance difference is less than the minimum movement distance, the cargo box door is controlled not to perform the closing operation.

[0022] Furthermore, after the step of generating the cargo box door control command based on the rainfall parameters, the method further includes:

[0023] Obtain preset alarm information, output the alarm information, and obtain the alarm playback time;

[0024] A preset time threshold is obtained, and the alarm playback time is compared with the time threshold to obtain a third comparison result;

[0025] When the third comparison result indicates that the alarm playback time is greater than or equal to a preset time threshold, the step of detecting the cargo box of the target vehicle according to the cargo box door control command to obtain the target opening value is executed.

[0026] Furthermore, after the step of detecting the environment around the target vehicle to obtain rainfall parameters, the method further includes:

[0027] Obtain the user location information of the user terminal corresponding to the target vehicle, and determine the distance value between the user terminal and the target vehicle based on the user location information and the vehicle location information of the target vehicle;

[0028] A preset distance threshold is obtained, and the distance value is compared with the distance threshold to obtain a fourth comparison result. When the fourth comparison result is that the distance value is greater than or equal to the preset distance threshold, the step of generating the cargo box door control command based on the rainfall parameter is executed.

[0029] Furthermore, to achieve the above objectives, the present invention also provides a control device for a vehicle cargo box door, the device comprising:

[0030] The instruction generation module is used to detect the environment around the target vehicle to obtain rainfall parameters, and generate cargo box door control instructions based on the rainfall parameters;

[0031] The opening calculation module is used to detect the cargo box of the target vehicle according to the cargo box door control command to obtain the target opening value;

[0032] The operation execution module is used to control the cargo box door to perform a closing operation based on the target opening value and the preset minimum movement distance.

[0033] In addition, to achieve the above objectives, the present invention also provides a terminal device, the terminal device comprising: a memory, a processor, and a vehicle cargo door control program stored in the memory and executable on the processor, wherein when the vehicle cargo door control program is executed by the processor, it implements the steps of the vehicle cargo door control method as described above.

[0034] In addition, to achieve the above objectives, the present invention also provides a computer-readable storage medium storing a control program for a vehicle cargo door, wherein when the vehicle cargo door control program is executed by a processor, it implements the steps of the vehicle cargo door control method described above.

[0035] The vehicle cargo box door control method, device, terminal equipment, and computer-readable storage medium provided in this invention detect the environment around the target vehicle to obtain rainfall parameters, and generate cargo box door control commands based on the rainfall parameters; detect the cargo box of the target vehicle according to the cargo box door control commands to obtain a target opening value; and control the cargo box door to perform a closing operation based on the target opening value and a preset minimum movement distance.

[0036] In this embodiment, when the terminal device is running, it first controls the sunlight and rain sensor configured in the terminal device to detect the surrounding environment of the target vehicle to obtain the rainfall parameters of the surrounding environment. The terminal device then inputs the rainfall parameters to the vehicle body controller configured in the terminal device. The vehicle body controller generates a cargo door control command based on the rainfall parameters. Then, the intelligent driving controller configured in the terminal device calls the internally configured sensor to detect the cargo box of the target vehicle according to the cargo door control command to obtain the cargo height value of the cargo box. The cargo height value is then input to the vehicle body controller. The vehicle body controller calculates the target opening value corresponding to the cargo door control command based on the cargo height value and inputs the target opening value to the cargo box controller configured in the terminal device. Finally, the cargo box controller obtains a preset minimum movement distance and determines the distance that the cargo door needs to move based on the minimum movement distance and the target opening value. Then, it controls the cargo door to perform a closing operation according to the distance.

[0037] Thus, this invention employs a method of detecting the surrounding environment of the target vehicle to obtain rainfall parameters, generating a cargo box door control command when the rainfall parameters are greater than or equal to a rainfall parameter threshold, detecting the cargo height value inside the cargo box, calculating the target opening value corresponding to the cargo box door control command based on the cargo height value, and finally controlling the cargo box door to perform a closing operation based on the target opening value, the minimum moving distance corresponding to the cargo box door, and the target opening value. In other words, this invention solves the technical problem of cargo box doors not being able to close automatically when the driver is not near the truck and the weather around the truck changes, resulting in the cargo inside the vehicle getting wet, by detecting the surrounding environment and automatically controlling the cargo box door to close when the rainfall parameters reach the rainfall parameter threshold.

[0038] Furthermore, by detecting the height of the cargo inside the cargo box and calculating the target opening value corresponding to the cargo box door control command based on the cargo height value, this invention also solves the technical problem that current anti-pinch and overcurrent protection functions can only be activated when the cargo box cover comes into contact with an obstacle and generates a certain resistance, thus causing the cargo to still be damaged. This invention achieves the technical effect of enabling the cargo box door to automatically close when the weather is abnormal, thereby preventing damage to the cargo during the closing process.

[0051] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on the terminal device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0052] like Figure 1 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a data storage module, a network communication module, a user interface module, and a control program for the vehicle cargo box door.

[0053] exist Figure 1 In the terminal device shown, the network interface 1004 is mainly used for data communication with other devices; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and memory 1005 in the terminal device of the present invention can be set in the terminal device, and the terminal device calls the control program of the vehicle cargo box door stored in the memory 1005 through the processor 1001 and performs the following operations:

[0054] The environment around the target vehicle is detected to obtain rainfall parameters, and a cargo box door control command is generated based on the rainfall parameters;

[0055] The cargo box of the target vehicle is detected according to the cargo box door control command to obtain the target opening value;

[0056] The cargo box door is controlled to close based on the target opening value and the preset minimum movement distance.

[0057] Furthermore, the terminal device, through processor 1001, calls the vehicle cargo door control program stored in memory 1005 and performs the following operations:

[0058] Obtain a preset rainfall parameter threshold, and compare the rainfall parameter with the rainfall parameter threshold to obtain a first comparison result;

[0059] When the first comparison result indicates that the rainfall parameter is greater than or equal to the rainfall parameter threshold, a cargo box door control command is generated.

[0060] Furthermore, the terminal device, through processor 1001, calls the vehicle cargo door control program stored in memory 1005 and performs the following operations:

[0061] The cargo box of the target vehicle is inspected to obtain the cargo height parameter of the cargo box;

[0062] The target opening value is calculated based on the cargo height parameters and the standard cargo box height parameters corresponding to the cargo box.

[0063] Furthermore, the terminal device, through processor 1001, calls the vehicle cargo door control program stored in memory 1005 and performs the following operations:

[0065] The distance difference is calculated based on the real-time opening value and the target opening value, and the cargo box door is controlled to close based on the distance difference and the minimum movement distance.

[0066] Furthermore, the terminal device, through processor 1001, calls the vehicle cargo door control program stored in memory 1005 and performs the following operations:

[0067] The second comparison result is obtained by comparing the minimum movement distance with the distance difference.

[0068] When the second comparison result is that the distance difference is greater than or equal to the minimum movement distance, the cargo box door is controlled to perform a closing operation according to the target opening value;

[0069] When the second comparison result is that the distance difference is less than the minimum movement distance, the cargo box door is controlled not to perform the closing operation.

[0070] Furthermore, the terminal device, through processor 1001, calls the vehicle cargo door control program stored in memory 1005 and performs the following operations:

When the fourth comparison result is that the distance value is greater than or equal to the preset distance threshold, the step of generating the cargo box door control command based on the rainfall parameter is executed.

[0077] Based on the aforementioned terminal equipment, various embodiments of the vehicle cargo box door control method of the present invention are provided.

[0078] Please refer to Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of the vehicle cargo box door control method of the present invention.

[0079] It should be understood that although the logical sequence is shown in the flowchart, in some cases, the method for controlling the vehicle cargo door of the present invention may of course perform the steps shown or described in a different order than that shown here.

[0080] In this embodiment, the vehicle cargo box door control method of the present invention may include the following steps:

[0081] Step S10: Detect the environment around the target vehicle to obtain rainfall parameters, and generate cargo box door control commands based on the rainfall parameters;

[0082] In this embodiment, when the terminal device is running, it first detects the surrounding environment of the target vehicle through the sensing device configured in the terminal device to obtain the rainfall parameters in the surrounding environment of the target vehicle, and inputs the rainfall parameters to the body controller, which then generates a cargo box door control command based on the rainfall parameters.

[0083] For example, please refer to Figure 5 , Figure 5 This is a schematic diagram of the cargo door control system according to an embodiment of the vehicle cargo door control method of the present invention. When the terminal device is running, it first detects the target vehicle to determine whether the target vehicle contains a target key. If it determines that the target vehicle does not contain a target key, it uses a mechanism configured in the terminal device such as... Figure 5 The solar and rain sensor shown detects the environment around the target vehicle. Then, the terminal device determines the rainfall parameters of the surrounding environment based on the signal sent by the solar and rain sensor and inputs the rainfall parameters to the vehicle body controller. The vehicle body controller then generates a cargo box door control command based on the rainfall parameters.

[0084] It should be noted that, as Figure 5 As shown, compared with the traditional cargo box cover control system, the intelligent driving controller in this embodiment is connected to the body controller via the vehicle bus, and the millimeter-wave radar is also connected to the intelligent driving controller. The body controller is also connected to the sunlight and rain sensor. In this way, the body controller can detect the surrounding environment of the target vehicle by controlling the sunlight and rain sensor to obtain rainfall parameters and generate cargo box door control commands based on the rainfall parameters. At the same time, the millimeter-wave radar detects the cargo box of the target vehicle to obtain the signal data collected by the millimeter-wave radar, and forwards the signal data to the intelligent driving controller via the vehicle bus, where the intelligent driving controller processes the acquired signal data.

[0085] Furthermore, in a feasible embodiment, the step of "generating cargo box door control instructions based on the rainfall parameters" in step S10 above may specifically include:

[0086] Step S101: Obtain a preset rainfall parameter threshold, and compare the rainfall parameter with the rainfall parameter threshold to obtain a first comparison result;

[0087] Step S102: When the first comparison result is that the rainfall parameter is greater than or equal to the rainfall parameter threshold, a cargo box door control command is generated;

[0088] For example, the terminal device first obtains the rainfall parameter threshold preset by the technician, and inputs the obtained rainfall parameter threshold and rainfall parameter into the data processing module in the vehicle body controller. The data processing module compares the rainfall parameter and the rainfall parameter threshold to obtain a first comparison result. Then, when the data processing module determines that the first comparison result is that the rainfall parameter is greater than or equal to the preset rainfall parameter threshold, the vehicle body controller determines that the environment around the target vehicle is abnormal and the target vehicle is in a rainy environment, thereby generating a cargo box door control command.

[0089] Step S20: Detect the cargo box of the target vehicle according to the cargo box door control command to obtain the target opening value;

[0090] In this embodiment, when the vehicle body controller generates a cargo box door control command, the intelligent driving controller configured in the terminal device controls the radar sensing module configured inside to detect the cargo box of the target vehicle, so as to obtain the cargo height parameter inside the cargo box of the target vehicle and input the cargo height parameter to the vehicle body controller. The vehicle body controller calculates the target opening value based on the cargo height parameter, and then inputs the target opening value to the cargo box controller.

[0091] For example, when the vehicle body controller generates a cargo box door control command, the intelligent driving controller configured in the terminal device first controls the millimeter-wave radar to detect the cargo box of the target vehicle to obtain the cargo height parameters corresponding to the cargo inside the cargo box and inputs the cargo height parameters to the vehicle body controller. Then, the vehicle body controller calculates based on the cargo height parameters to determine the closing position corresponding to the cargo box lid, thereby determining the target opening value based on the closing position and inputting the target opening value to the cargo box controller.

[0092] Furthermore, in a feasible embodiment, step S20 above may specifically include:

[0093] Step S201: Detect the cargo box of the target vehicle to obtain the cargo height parameter of the cargo box;

[0094] Step S202: Calculate the target opening value based on the cargo height parameter and the standard cargo box height parameter corresponding to the cargo box;

[0095] For example, when the vehicle body controller generates a cargo box door control command, the terminal device controls the millimeter-wave radar to scan the cargo inside the cargo box of the target vehicle to obtain the cargo height parameters corresponding to the cargo box. Then, the millimeter-wave radar inputs the obtained height parameters to the intelligent driving controller configured in the terminal device. The intelligent driving controller reads the storage device configured in the vehicle body controller to obtain the standard cargo box height parameters pre-stored by the technician. Then, the intelligent driving controller calculates based on the obtained cargo height parameters and the standard cargo box height parameters to determine the position where the cargo box door can be closed, and then determines the closing position as the target opening value, and inputs the target opening value to the vehicle body controller. Finally, the vehicle body controller inputs the target opening value to the cargo box controller so that the cargo box controller can control the cargo box to perform a closing operation based on the target opening value.

[0096] Step S30: Control the cargo box door to close according to the target opening value and the preset minimum movement distance;

[0097] In this embodiment, the cargo box controller reads the storage device configured in the cargo box controller to obtain the minimum movement distance preset by the technician, and controls the cargo box door to perform a closing operation according to the calculated target opening value and minimum movement distance.

[0098] For example, the cargo box controller first reads the storage device to obtain the minimum movement distance preset by the technician, and determines the movement distance of the cargo box lid based on the calculated target opening value and the minimum movement distance. Then, it controls the movement of the cargo box lid according to the movement distance so that the cargo box lid moves to the target position to complete the closing operation.

[0099] Furthermore, in a feasible embodiment, step S30 above may specifically include:

[0100] Step S301: Obtain the preset minimum movement distance and the real-time opening value of the cargo box;

[0101] Step S302: Calculate the distance difference based on the real-time opening value and the target opening value, and control the cargo box door to perform a closing operation based on the distance difference and the minimum movement distance;

[0102] For example, the cargo box controller first reads the storage device configured in the cargo box controller to obtain the minimum movement distance of the cargo box preset by the technician. At the same time, the terminal device controls the millimeter-wave radar to detect the cargo box door to determine the current position of the cargo box door. Based on the current position of the cargo box door, the real-time opening value corresponding to the cargo box door is determined and input to the cargo box controller. Then, the cargo box controller calculates the distance difference between the real-time opening value and the target opening value based on the obtained real-time opening value and the target opening value. The cargo box controller then controls the cargo box door to perform a closing operation based on the distance difference and the minimum movement distance.

[0103] Furthermore, in a feasible embodiment, step S302 above may specifically include:

[0104] Step S3021: Compare the minimum movement distance with the distance difference to obtain a second comparison result;

[0105] Step S3022: When the second comparison result is that the distance difference is greater than or equal to the minimum movement distance, control the cargo box door to perform a closing operation according to the target opening value;

[0106] Step S3023: When the second comparison result is that the distance difference is less than the minimum movement distance, control the cargo box door not to perform the closing operation;

[0107] For example, after acquiring the distance difference, the cargo box controller first compares the distance difference with the acquired minimum movement distance to obtain a second comparison result. Then, when the cargo box controller determines that the second comparison result is that the distance difference is greater than or equal to the minimum movement distance, it determines that the cargo box door will not get caught in the cargo and stop when it moves. Therefore, it controls the cargo box door support to move so that the cargo box door moves to the target position according to the target opening to complete the closing operation. Similarly, when the cargo box controller determines that the second comparison result is that the distance difference is less than the minimum movement distance, it determines that the cargo box door will get caught in the cargo before moving to the minimum distance, so it does not perform the cargo box door closing operation.

[0108] In this embodiment, when the terminal device is running, it first detects the surrounding environment of the target vehicle through the sensors configured in the terminal device to obtain the rainfall parameters in the surrounding environment of the target vehicle, and inputs the rainfall parameters to the body controller. The body controller generates a cargo box door control command based on the rainfall parameters. Then, when the body controller generates the cargo box door control command, the intelligent driving controller configured in the terminal device first controls the millimeter-wave radar to detect the cargo box of the target vehicle to obtain the cargo height parameters corresponding to the cargo in the cargo box, and inputs the cargo height parameters to the body controller. Then, the body controller calculates based on the cargo height parameters to determine the corresponding closed position of the cargo box lid, thereby determining the target opening value based on the closed position, and inputting the target opening value to the cargo box controller. Finally, the cargo box controller reads the minimum movement distance preset by the technician from the storage device configured in the cargo box controller, and controls the cargo box door to perform a closing operation based on the calculated target opening value and minimum movement distance.

[0109] Thus, this invention employs a method of detecting the surrounding environment of the target vehicle to obtain rainfall parameters, generating a cargo box door control command when the rainfall parameters are greater than or equal to a rainfall parameter threshold, detecting the cargo height value inside the cargo box, calculating the target opening value corresponding to the cargo box door control command based on the cargo height value, and finally controlling the cargo box door to perform a closing operation based on the target opening value, the minimum moving distance corresponding to the cargo box door, and the target opening value. In other words, this invention solves the technical problem of cargo box doors not being able to close automatically when the driver is not near the truck and the weather around the truck changes, resulting in the cargo inside the vehicle getting wet, by detecting the surrounding environment and automatically controlling the cargo box door to close when the rainfall parameters reach the rainfall parameter threshold.

[0110] Furthermore, by detecting the height of the cargo inside the cargo box and calculating the target opening value corresponding to the cargo box door control command based on the cargo height value, this invention also solves the technical problem that current anti-pinch and overcurrent protection functions can only be activated when the cargo box cover comes into contact with an obstacle and generates a certain resistance, thus causing the cargo to still be damaged. This invention achieves the technical effect of enabling the cargo box door to automatically close when the weather is abnormal, thereby preventing damage to the cargo during the closing process.

[0111] Further, please refer to Figure 3 , Figure 3 This is a flowchart illustrating the second embodiment of the vehicle cargo box door control method of the present invention;

[0112] Based on the first embodiment of the vehicle cargo box door control method of the present invention described above, a second embodiment of the vehicle cargo box door control method of the present invention is hereby proposed.

[0113] After step S10 above, the vehicle cargo box door control method of the present invention may further include the following steps:

[0114] Step A10: Obtain preset alarm information, output the alarm information and obtain the alarm playback time;

[0115] In this embodiment, the terminal device reads the storage device to obtain the alarm information pre-stored by the technician, and sends the obtained alarm information to the user terminal corresponding to the target vehicle through the bus configured in the terminal device. At the same time, the terminal device calls the detection device to detect the user terminal, and when it detects that the user terminal has received the alarm information, it records the playback time of the alarm information to obtain the alarm playback time.

[0116] Step A20: Obtain a preset time threshold and compare the alarm playback time with the time threshold to obtain a third comparison result;

[0117] In this embodiment, the terminal device obtains a time threshold preset by the technician and compares the detected alarm playback time with the time threshold to obtain a third comparison result.

[0118] Step A30: When the third comparison result is that the alarm playback time is greater than or equal to a preset time threshold, the step of detecting the cargo box of the target vehicle according to the cargo box door control command to obtain the target opening value is executed.

[0119] In this embodiment, when the terminal device determines that the alarm playback time is greater than or equal to the time threshold in the third comparison result, it determines that the notification to the user terminal has been completed, thereby controlling the intelligent driving controller to detect the cargo box of the target vehicle to obtain the target opening value.

[0120] For example, the terminal device first reads the storage device to obtain the alarm information pre-stored by the technician, and converts the alarm information into a visual interface. The visual interface is then sent to the user terminal bound to the target vehicle via a bus configured within the terminal device, so that the user terminal can view the alarm information through the visual interface. At the same time, the terminal device calls the detection device to detect the user terminal, and records the information playback time when it is determined that the user terminal has received the alarm information, thereby obtaining the alarm playback time. Afterwards, the terminal device obtains the time threshold preset by the technician, and then compares the obtained alarm playback time with the time threshold to obtain a third comparison result. When the terminal device determines that the third comparison result is that the alarm playback time is greater than or equal to the time threshold, it determines that the alarm notification to the user terminal has been completed, thereby controlling the intelligent driving controller to detect the cargo box of the target vehicle to obtain the target opening value.

[0121] In this embodiment, the terminal device reads the storage device to obtain the alarm information pre-stored by the technician, and sends the obtained alarm information to the user terminal corresponding to the target vehicle through the bus configured in the terminal device. At the same time, the terminal device calls the detection device to detect the user terminal, and when it detects that the user terminal has received the alarm information, it records the playback time of the alarm information to obtain the alarm playback time. Then, the terminal device obtains the time threshold preset by the technician, and compares the detected alarm playback time with the time threshold to obtain a third comparison result. Finally, when the terminal device determines that the third comparison result is that the alarm playback time is greater than or equal to the time threshold, it determines that the notification to the user terminal has been completed, thereby controlling the intelligent driving controller to detect the cargo box of the target vehicle to obtain the target opening value.

[0122] Thus, by acquiring preset alarm information, sending the alarm information to the user terminal bound to the target vehicle and recording the alarm playback time, and then detecting the cargo box of the target vehicle to obtain the target opening value when the alarm playback time is greater than or equal to a preset time threshold, the present invention achieves the purpose of showing alarm information to the driver before the cargo box door is automatically closed according to the cargo box door control command.

[0123] Further, please refer to Figure 4 , Figure 4 This is a flowchart illustrating the third embodiment of the vehicle cargo box door control method of the present invention.

[0124] Based on the first and / or second embodiments of the vehicle cargo door control method of the present invention described above, a third embodiment of the vehicle cargo door control method of the present invention is hereby proposed.

[0125] Following the step of "detecting the environment around the target vehicle to obtain rainfall parameters" in step S10 above, the vehicle cargo box door control method of the present invention may further include the following steps:

[0126] Step B10: Obtain the user location information of the user terminal corresponding to the target vehicle, and determine the distance between the user terminal and the target vehicle based on the user location information and the vehicle location information of the target vehicle;

[0127] In this embodiment, the terminal device detects the user terminal to obtain the user's location information. At the same time, the terminal device obtains the vehicle location information corresponding to the target vehicle based on preset map data. The terminal device then determines the distance between the user terminal and the target vehicle based on the user location information and the vehicle location information.

[0128] Step B20: Obtain a preset distance threshold, and compare the distance value with the distance threshold to obtain a fourth comparison result. When the fourth comparison result is that the distance value is greater than or equal to the preset distance threshold, execute the step of generating cargo box door control instructions based on the rainfall parameters.

[0129] In this embodiment, the terminal device reads the storage device to obtain the distance threshold preset by the technician, and compares the obtained distance value with the distance threshold to obtain a fourth comparison result. When the terminal device determines that the fourth comparison result is that the distance value is greater than or equal to the distance threshold, it generates a cargo box door control command based on the obtained rainfall parameters.

[0130] For example, the terminal device calls the detection device to detect the user terminal bound to the target vehicle to obtain the user location information of the user terminal. Then, the terminal device obtains preset map data and determines the vehicle location information of the target vehicle based on the map data. The terminal device then determines the distance value between the user terminal and the target vehicle based on the user location information and the vehicle location information. After that, the terminal device reads the storage device to obtain the distance threshold preset by the technician and compares the distance value with the distance threshold to obtain a fourth comparison result. When the terminal device determines that the fourth comparison result is that the distance value is greater than or equal to the distance threshold, it generates a cargo box door control command based on the obtained rainfall parameters.

[0131] In this embodiment, the terminal device detects the user terminal to obtain the user's location information. Simultaneously, the terminal device obtains the vehicle location information corresponding to the target vehicle based on preset map data. The terminal device then determines the distance value between the user terminal and the target vehicle based on the user location information and the vehicle location information. Afterward, the terminal device reads the storage device to obtain a distance threshold preset by the technician, and compares the obtained distance value with the distance threshold to obtain a fourth comparison result. When the terminal device determines that the fourth comparison result is that the distance value is greater than or equal to the distance threshold, it generates a cargo box door control command based on the obtained rainfall parameters.

[0132] Thus, by detecting the location information of the user terminal and the target vehicle to determine the distance between them, and then detecting the rainfall parameters of the surrounding environment when the distance is greater than a preset distance threshold, the present invention further controls the automatic closing of the cargo box door based on the rainfall parameters. This achieves the purpose of enabling the terminal device to detect whether the driver is near the target vehicle in a timely manner, and to control the cargo box door to close automatically when it is determined that the driver is not near the target vehicle.

[0133] Further, please refer to Figure 6 , Figure 6 This is a flowchart illustrating a preferred embodiment of the vehicle cargo box door control method of the present invention;

[0134] Based on the above embodiments of the vehicle cargo door control method of the present invention, a preferred embodiment of the vehicle cargo door control method of the present invention is hereby proposed.

[0135] In this embodiment, when the terminal device is running, it first calls the detection device to detect the target vehicle to determine whether the cargo box of the target vehicle is open and whether the smart closing option for the cargo box of the target vehicle is turned on (i.e., Figure 6 In step 1), when the terminal device determines that the cargo box is open and the smart closing option of the cargo box is on, the terminal device further uses a detection device to detect the target vehicle to determine whether the target vehicle contains a key (i.e., ...). Figure 6 In step 2), when the terminal device determines that the target vehicle does not contain a key, the terminal device calls its internally configured solar and rain sensors to detect the environment around the target vehicle to obtain a rainfall signal (i.e., Figure 6 Step 3), and upon receiving a rainfall signal from the solar rain sensor, or upon the terminal device detecting that a key is present in the target vehicle and receiving a tailgate closing command (i.e. Figure 6 In step 4), the terminal device calls its internally configured millimeter-wave radar to detect the cargo box and feeds back the detected data to the intelligent driving controller configured within the terminal device (i.e., Figure 6In step 5), the intelligent driving controller calculates the cargo height parameter corresponding to the cargo in the cargo box based on the acquired parameters. The intelligent driving controller then calculates the target opening percentage A based on the calculated cargo height parameter and the standard height parameter of the cargo box. Finally, the intelligent driving controller inputs the obtained target opening percentage A to the vehicle control unit (i.e., ...). Figure 6 In step 6), the vehicle body controller forwards the target opening percentage A to the cargo box controller configured in the terminal device (i.e., Figure 6 In step 7), the cargo box controller simultaneously acquires the real-time opening percentage B and the minimum moving distance C of the cargo box, calculates the difference between the target opening percentage A and the real-time opening percentage B, and then compares the difference with the minimum moving distance C to determine whether the difference is greater than the minimum moving distance C (i.e., ...). Figure 6 In step 8), when the cargo box controller determines that the difference is greater than the minimum moving distance C, the terminal device further determines whether the received door closing request comes from the sunlight and rain sensor (i.e., Figure 6 In step 10), and upon determining that the door closing request originates from the sunlight and rain sensor, the terminal device acquires a preset alarm message and controls the vehicle body controller to provide continuous audible and visual feedback for 2 seconds according to the alarm message (i.e., Figure 6 Step 11) is performed so that after the audio-visual feedback is completed, the cargo box controller drives the strut to execute the closing command according to the target opening percentage A (i.e., Figure 6 In step 12), similarly, when the cargo box controller determines that the difference is less than or equal to the minimum moving distance C, the terminal device obtains the preset alarm information and controls the body controller to provide continuous audible and visual feedback for 2 seconds according to the alarm information and controls the cargo box not to perform the closing operation (i.e. Figure 6 Step 9 in the process.
