[0001] This application relates to the field of automotive technology, and in particular to a multi-functional control method, system and device for a vehicle sunroof in an MPV model. Background Technology

[0002] Currently, most existing car rain protection devices are manually installed door rain shields, which can only achieve a simple rain protection function, cannot be automatically extended or retracted, and do not have the function of camping awnings; while standalone camping awnings need to be carried and set up separately, have low integration with the car body, and cannot meet the one-stop rain protection and camping needs of MPV users. Summary of the Invention

[0003] The main objective of this application is to propose a multi-functional control method, system, and device for the vehicle sunroof of an MPV model, which can meet the one-stop rain shelter and camping needs of MPV users.

[0004] To achieve the above objectives, one aspect of this application proposes a multi-functional control method for a vehicle sunroof in an MPV model. This method is executed by a multi-functional vehicle sunroof device, which includes a sensing component, a controller, and a drive motor. The method includes the following steps: The sensing components are used to acquire rainfall signals, user intention to get out of the car prediction signals, and door opening angles. The controller outputs a first control signal based on the rainfall signal and the user's intention to get out of the vehicle, and determines the target travel position based on the door opening angle. The drive motor controls the vehicle sunroof to extend to the target travel position according to the first control signal; If a camping start signal triggered by a user is received, the controller outputs a second control signal based on the camping start signal. The drive motor controls the vehicle sunroof to extend to its maximum travel position according to the second control signal.

[0005] In some embodiments, the sensing components include a rain sensor, a seatbelt buckle switch, a pressure sensor, a touch sensor, and an angle sensor. The user's intention to exit the vehicle prediction signal includes a seatbelt buckle status signal, a seat pressure change value, and a door handle touch signal. Acquiring the rainfall signal, the user's intention to exit the vehicle prediction signal, and the door opening angle through the sensing components specifically includes: The rainfall signal is acquired using the rain sensor. The seatbelt buckle status signal is obtained through the seatbelt buckle switch; The pressure sensor installed under the seat cushion acquires the seat pressure change value; The touch sensor located inside the door handle acquires the touch signal of the door handle; The door opening angle is obtained by the angle sensor installed on the door hinge or door limiter.

[0006] In some embodiments, the user's intention to exit the vehicle prediction signal includes a seatbelt buckle status signal, a seat pressure change value, and a door handle touch signal. The step of the controller outputting a first control signal based on the rainfall signal and the user's intention to exit the vehicle prediction signal specifically includes: When the rainfall signal exceeds a preset rainfall threshold, the system enters a rain shelter standby state. In the rain-proof standby state, a first control signal is output based on the user's intention to get off the vehicle prediction signal.

[0007] In some embodiments, the step of outputting a first control signal based on the user's intention to get out of the vehicle prediction signal in the rain-proof standby state specifically includes: Set up a stress rating scale and score weights; In the rain-proof standby state, the seat pressure change value is mapped to the pressure scoring calibration table to obtain a pressure change score; Based on the scoring weights, the seatbelt buckle status signal, the pressure change score, and the door handle touch signal are weighted and fused to obtain the vehicle exit intention prediction value. When the predicted value of the intention to get off the vehicle is greater than the preset prediction threshold, the first control signal is output.

[0008] In some embodiments, determining the target travel position based on the door opening angle specifically includes: When the opening angle of the vehicle door is less than the first threshold, the extension ratio function of the vehicle sunroof is determined to be zero. When the opening angle of the vehicle door is greater than or equal to the first threshold and less than the second threshold, the extension ratio function of the vehicle sunroof is determined to be the first value. When the opening angle of the vehicle door is greater than or equal to the second threshold and less than the third threshold, the extension ratio function of the vehicle sunroof is determined to be the second value. When the opening angle of the vehicle door is greater than or equal to the third threshold, the extension ratio function of the vehicle sunroof is determined to be the third value. Based on the door length and the door opening angle, the door opening width is calculated, and then the product of the door opening width and the extension ratio function is calculated to obtain the target travel position. Wherein, the first threshold is less than the second threshold, the second threshold is less than the third threshold, the first value is less than the second value, and the second value is less than the third value.

[0009] In some embodiments, the vehicle sunroof multi-functional device further includes a mounting assembly, and after controlling the vehicle sunroof to extend to the target travel position via the drive motor according to the first control signal, the method further includes: When the door opening angle is zero, or the rainfall signal is zero, or a user-triggered sunroof closing signal is received, the controller outputs a third control signal. The drive motor controls the vehicle sunroof to retract completely into the mounting assembly according to the third control signal.

[0010] In some embodiments, the sensing component includes a wind speed sensor, and after controlling the vehicle sunroof to extend to its maximum travel position via the drive motor according to the second control signal, the method further includes: Instantaneous wind speed signals are collected using the aforementioned wind speed sensor; When the instantaneous wind speed signal exceeds a preset wind speed threshold, the controller outputs a voice alarm signal.

[0011] To achieve the above objectives, another aspect of this application proposes a multi-functional control system for a vehicle sunroof in an MPV model. This system is executed by a multi-functional vehicle sunroof device, which includes a sensing component, a controller, and a drive motor. The system includes: The signal acquisition module is used to acquire rainfall signals, user intention to get out of the car prediction signals, and door opening angle through the sensing components. The first control signal determination module is used to output a first control signal through the controller based on the rainfall signal and the user's intention to get out of the vehicle prediction signal, and to determine the target travel position based on the door opening angle. The first skylight control module is used to control the vehicle skylight to extend to the target travel position according to the first control signal via the drive motor; The second control signal determination module is used to output a second control signal based on the camping start signal triggered by the user, through the controller; The second skylight control module is used to control the vehicle skylight to extend to its maximum travel position via the drive motor according to the second control signal.

[0012] To achieve the above objectives, another aspect of this application provides an electronic device, which includes a memory and a processor. The memory stores a computer program, and the processor executes the computer program to implement the method described above.

[0013] To achieve the above objectives, another aspect of the embodiments of this application proposes a computer program product, including a computer program that, when executed by a processor, implements the aforementioned method.

[0014] The embodiments of this application include at least the following beneficial effects: The multi-functional control method, system, and device for the vehicle sunroof of the MPV model of this application are executed by a multi-functional vehicle sunroof device, which includes a sensing component, a controller, and a drive motor. First, the sensing component acquires a rainfall signal, a user's intention to get out of the vehicle prediction signal, and the door opening angle. Then, the controller outputs a first control signal based on the rainfall signal and the user's intention to get out of the vehicle prediction signal, and determines the target travel position based on the door opening angle. Then, the drive motor controls the vehicle sunroof to extend to the target travel position based on the first control signal. If a camping activation signal triggered by the user is received, the controller outputs a second control signal based on the camping activation signal. Then, the drive motor controls the vehicle sunroof to extend to the maximum travel position based on the second control signal. This application determines whether it is raining and whether the user intends to get out of the vehicle based on rainfall signals, user intention to get out signals, and door opening angles. It then automatically controls the vehicle's sunroof to extend to the target travel position without requiring manual operation from the user. Furthermore, when the user triggers the camping activation signal, it can be fully extended as a sunroof, eliminating the need to carry additional camping equipment, saving interior space, reducing travel costs, and meeting the one-stop rain shelter and camping needs of MPV users.

[0019] Currently, most existing car rain protection devices are manually installed door rain shields, which can only achieve a simple rain protection function, cannot be automatically extended or retracted, and do not have the function of camping awnings; while standalone camping awnings need to be carried and set up separately, have low integration with the car body, and cannot meet the one-stop rain protection and camping needs of MPV users.

[0020] In view of this, this application proposes a multi-functional control method for a vehicle sunroof in an MPV model. This method is executed by a multi-functional vehicle sunroof device, which includes a sensing component, a controller, and a drive motor. First, the sensing component acquires a rainfall signal, a user's intention to get out of the vehicle predicted signal, and the door opening angle. Then, the controller outputs a first control signal based on the rainfall signal and the user's intention to get out of the vehicle predicted signal, and determines a target travel position based on the door opening angle. Next, the drive motor controls the vehicle sunroof to extend to the target travel position based on the first control signal. If a camping activation signal triggered by the user is received, the controller outputs a second control signal based on the camping activation signal. Then, the drive motor controls the vehicle sunroof to extend to its maximum travel position based on the second control signal. This application determines whether it is raining and whether the user intends to get out of the vehicle based on the rainfall signal, the user's intention to get out of the vehicle predicted signal, and the door opening angle, and then automatically controls the vehicle sunroof to extend to the target travel position without manual operation by the user. Furthermore, when the user triggers the camping activation signal, the sunroof can be fully extended and used as a sunroof, eliminating the need to carry additional camping equipment, saving interior space, reducing travel costs, and meeting the one-stop rain shelter and camping needs of MPV users.

[0021] Figure 1 This is a schematic diagram of the structure of a multi-functional vehicle sunroof device according to one embodiment of this application. This application is based on a multi-functional vehicle sunroof device, such as... Figure 1 As shown, the multi-functional sunroof device includes a sensing component, a controller, a drive motor, and a mounting component. The mounting component is fixed to the inner side of the upper edge of the MPV door. The sunroof body can be retracted and stored in the mounting component. The drive motor is connected to the sunroof body and drives its extension and retraction. The sensing component includes a rain sensor, a seat belt buckle switch, a pressure sensor, a touch sensor, an angle sensor, and a wind speed sensor, used to detect rainfall signals, user intention to get out of the vehicle prediction signals, seat pressure change values, door opening angle, and wind speed signals. The controller is electrically connected to the drive motor and the sensing component respectively, and controls the start and stop of the drive motor.

[0022] Reference Figure 2 , Figure 2 This is a flowchart illustrating the steps of a multi-functional control method for a vehicle sunroof in an MPV model according to an embodiment of this application. The embodiment proposes a multi-functional control method for a vehicle sunroof in an MPV model, executed by a multi-functional vehicle sunroof device. The multi-functional vehicle sunroof device includes a sensing component, a controller, and a drive motor. The method may include, but is not limited to, the following steps S101 to S105: Step S101: Acquire rainfall signal, user's intention to get out of the car prediction signal, and door opening angle through the sensing component; As a further optional implementation, the sensing components include a rain sensor, a seatbelt buckle switch, a pressure sensor, a touch sensor, and an angle sensor. The user's intention to exit the vehicle prediction signal includes a seatbelt buckle status signal, a seat pressure change value, and a door handle touch signal. Step S101 can be further divided into the following steps S1011 to S1015: Step S1011: Obtain rainfall signals using a rain sensor; Step S1012: Obtain the seat belt buckle status signal via the seat belt buckle switch; Step S1013: Obtain the seat pressure change value by using a pressure sensor installed under the seat cushion; Step S1014: Obtain the door handle touch signal through the touch sensor located on the inside of the door handle; Step S1015: Obtain the door opening angle using an angle sensor installed on the door hinge or door limiter.

[0023] Specifically, after the vehicle is powered on, the controller performs a self-test on all sensors in the sensing assembly. If the self-test passes, the system enters standby mode and cyclically scans all sensor signals at a preset sampling period.

[0024] In some optional embodiments, the sensing components include a rain sensor, a seatbelt buckle switch, a pressure sensor, a touch sensor, and an angle sensor. The rain sensor is used to collect rainfall data in real time, i.e., a rainfall signal; the seatbelt buckle switch is located inside the seatbelt buckle of each seat and is used to detect the insertion and removal status of the seatbelt insert, obtaining a seatbelt buckle status signal; the pressure sensor is a thin-film pressure sensor located between the seat cushion foam layer and the seat frame, used to continuously detect the pressure value and its changing trend on the seat, obtaining a seat pressure change value; the touch sensor is a capacitive touch sensor embedded inside the door handle, used to detect the user's finger touching the handle and output a door handle touch signal when a touch occurs; the angle sensor is a Hall angle sensor located at the sliding door hinge or inside the limiter, used to continuously detect the opening angle of the door relative to the side of the vehicle body, i.e., the door opening angle.

[0025] Step S102: The controller outputs a first control signal based on the rainfall signal and the user's intention to get out of the vehicle, and determines the target travel position based on the door opening angle. Specifically, the controller outputs a first control signal to drive the vehicle sunroof to extend based on the rainfall signal and the user's intention to get out of the vehicle, and determines the target travel position of the vehicle sunroof extension based on the door opening angle.

[0026] As a further optional implementation, the user's intention to exit the vehicle prediction signal includes a seatbelt buckle status signal, a seat pressure change value, and a door handle touch signal. The step of the controller outputting a first control signal based on the rainfall signal and the user's intention to exit the vehicle prediction signal can be further divided into the following steps S1021 to S1022: Step S1021: When the rainfall signal exceeds the preset rainfall threshold, enter the rain shelter standby state; Step S1022: In the rain-proof standby state, output the first control signal based on the user's intention to get off the vehicle prediction signal.

[0027] Specifically, if the real-time rainfall displayed by the rainfall signal exceeds a preset rainfall threshold (e.g., 0.2 mm / h) and the signal remains continuously for more than 200 ms, it is determined that the vehicle's driving environment is in rain, and the vehicle automatically enters a rain shelter standby state. In the rain shelter standby state, the controller continuously collects seat belt buckle status signals, seat pressure change values, and door handle touch signals, performs weighted fusion calculation on the above signals to determine the vehicle exit intention prediction value, and outputs a first control signal based on the vehicle exit intention prediction value.

[0028] As an optional implementation, step S1022 can be further divided into the following steps S10221 to S10224: Step S10221: Set the stress rating calibration table and score weights; Step S10222: In the rain-proof standby state, map the seat pressure change value to the pressure scoring calibration table to obtain the pressure change score; Step S10223: Based on the scoring weights, the seat belt buckle status signal, the pressure change score, and the door handle touch signal are weighted and fused to obtain the predicted value of the intention to get out of the vehicle. Step S10224: When the predicted value of the vehicle's intention to disembark is greater than the preset prediction threshold, output the first control signal.

[0029] It should be noted that, in order to solve the problems of high false judgment rate and response lag of single signal, the embodiments of this application use weighted fusion to quantify the intention to get off the vehicle, which can avoid false triggering caused by the user only unfastening the seat belt to rest or accidentally touching the door. When a single sensor fails, the intention to get off the vehicle can still work normally; and the sunroof can be pre-extended before the door is opened, thereby achieving the synchronization of sunroof rain protection and passenger disembarkation.

[0030] Specifically, a pressure scoring calibration table and the scoring weights of each component are pre-stored within the controller. The pressure scoring calibration table defines the mapping relationship between seat pressure changes and pressure change scores. For example, when the pressure drop slope is less than 10 N / s, the score is 0; when the pressure drop slope is greater than or equal to 10 N / s and less than 30 N / s, the score is 50; and when the pressure drop slope is greater than or equal to 30 N / s, the score is 100. A seatbelt buckle status signal is then set. The score weight is 0.5, and the score weight for stress change is... The score weight for the door handle touch signal is 0.3. The value is 0.2. It's understandable that the stress scoring calibration table and the weighting of each component can be calibrated based on the actual vehicle model, user group, and usage scenario.

[0031] In the rain-proof standby state, the pressure drop slope of the current pressure relative to the previous cycle is calculated based on the seat pressure change value. Then, the calculated pressure drop slope is compared and mapped with the pressure scoring calibration table to obtain the corresponding pressure change score. Simultaneously, it reads the seatbelt buckle switch signal and the door handle touch signal. When the seatbelt is pulled out, the seatbelt buckle status score is calculated. The value is 100, which represents the score for the seatbelt buckle status when inserted. The value is 0; when the controller is touched, the controller touch score is... The value is 100, which is the touch score of the controller when it is not touched. The value is 0. The three scores are then weighted and summed according to their respective weights to calculate the predicted disembarkation intention value. : = ; Finally, the calculated predicted value of the user's intention to get off the vehicle is compared with a preset prediction threshold, and a first control signal is output. For example, when the predicted value is greater than or equal to 65 points and remains stable for more than 100ms, it is determined that the user is preparing to get off the vehicle. The controller outputs a first control signal for forward rotation, controlling the drive motor to perform the extension action, and the canopy extends synchronously to provide rain protection when the user gets off the vehicle.

[0032] As an optional implementation, the step of determining the target travel position based on the door opening angle can be further divided into the following steps S1023 to S1027: Step S1023: When the door opening angle is less than the first threshold, determine that the extension ratio function of the vehicle sunroof is zero; Step S1024: When the door opening angle is greater than or equal to the first threshold and less than the second threshold, determine the extension ratio function of the vehicle sunroof as the first value. Step S1025: When the door opening angle is greater than or equal to the second threshold and less than the third threshold, determine the extension ratio function of the vehicle sunroof as the second value. Step S1026: When the door opening angle is greater than or equal to the third threshold, determine the extension ratio function of the vehicle sunroof as the third value. Step S1027: Calculate the door opening width based on the door length and door opening angle, and then calculate the product of the door opening width and the extension ratio function to obtain the target travel position; Among them, the first threshold is less than the second threshold, the second threshold is less than the third threshold, the first value is less than the second value, and the second value is less than the third value.

[0033] In some optional embodiments, after confirming that the user intends to get out of the vehicle, the controller reads the door opening angle collected by the angle sensor. And compare it with a preset first threshold (e.g., 15°). When the door opens at an angle... When the angle is less than 15°, it is determined that the car door is only slightly open, and the extension ratio function is then determined. The canopy will not extend to avoid frequent invalid operations.

[0034] When the car door opens at an angle When the angle is greater than or equal to 15° and less than the second threshold (e.g., 30°), the door is determined to be in a small-angle open state, possibly indicating the user is reaching for something or needing temporary ventilation. In this case, the extension ratio function is determined. The first value (e.g., 0.5) is used to ensure the rain-proof effect while avoiding excessive extension of the canopy that could cause interference.

[0035] When the car door opens at an angle When the angle is greater than or equal to 30° and less than the third threshold (e.g., 60°), the door is determined to be in a mid-angle opening state, which is the typical range for passengers to normally get on and off the vehicle. At this point, the extension ratio function is determined. The second value (e.g., 1.0) provides the user with sufficient rain protection coverage.

[0036] When the car door opens at an angle When the angle is greater than or equal to 60°, the door is determined to be in a large-angle or fully open state, commonly seen when users are getting on or off the vehicle with luggage or when multiple people are getting on or off the vehicle simultaneously. In this case, the extension ratio function is determined. The third value (e.g., 1.2) means that the sunroof completely covers the width of the door opening, achieving the maximum rain protection range.

[0037] Determine the extension ratio function Then, based on the current door opening angle and door length The width of the car door opening can be calculated using the following formula. : ; Then the width of the car door opening The extension ratio function determined in steps S1024 to S1026 Multiply the values ​​to obtain the target travel position of the canopy, and the controller will immediately control the drive motor to extend the canopy to that target travel position.

[0038] Understandably, the first threshold, second threshold, third threshold, first value, second value, and third value can be set according to actual needs, and the first threshold... Second threshold Third threshold, first value Second value The third value.

[0039] Step S103: Using the drive motor, control the vehicle sunroof to extend to the target travel position according to the first control signal; As an optional implementation, the vehicle sunroof multi-function device further includes a mounting assembly. After step S103, the vehicle sunroof multi-function control method for this MPV model may further include the following steps S1031 to S1032: Step S1031: When the door opening angle is zero, or the rainfall signal is zero, or a sunroof closing signal triggered by the user is received, the controller outputs a third control signal. Step S1032: Using the drive motor, control the vehicle sunroof to fully retract into the mounting assembly according to the third control signal.

[0040] Specifically, in automatic rain-shielding mode, the controller continuously monitors the trigger conditions for the sunroof to retract. The controller determines that the retraction conditions are met when either of the following conditions is detected: the door opening angle is detected. A zero signal indicates the doors are fully closed; a zero rainfall signal indicates the rain has stopped; and a user has actively triggered the sunroof closing signal via virtual buttons on the central control screen, physical buttons in the rear seats, or a mobile app. When any of these conditions are met, the controller outputs a reversed third control signal, controlling the drive motor to fully retract the sunroof.

[0041] It should be noted that, in order to meet the user's need for manual adjustment, the embodiments of this application set the priority of manual control to be higher than that of automatic control, so as to improve the flexibility of use.

[0042] Step S104: If a camping start signal triggered by the user is received, the controller outputs a second control signal according to the camping start signal. Step S105: Using the drive motor, control the vehicle sunroof to extend to its maximum travel position according to the second control signal.

[0043] Specifically, if the controller receives a camping activation signal triggered by the user via virtual buttons on the vehicle's central control screen, physical buttons in the rear seats, or a remote command via a mobile app, it immediately performs a mode switching operation. First, it locks all triggering logic for the automatic rain-shielding mode to prevent the sunroof from retracting abnormally due to rain signals or changes in the vehicle's door status during camping. Then, it outputs a second control signal for forward rotation to the drive motor, causing the motor to run at full speed and control the sunroof to extend continuously until it reaches the mechanical limit switch position, i.e., the preset maximum travel position. Once the sunroof is in place, the controller automatically cuts off the motor power supply and locks the current position. The user then secures the sunroof using ground stakes or suction cups, thus realizing the camping sunroof function.

[0044] As a further optional implementation, the sensing component includes a wind speed sensor. After step S105, the multi-functional control method for the vehicle sunroof of this MPV model may also include the following steps S1051 to S1052: Step S1051: Collect instantaneous wind speed signals using a wind speed sensor; Step S1052: When the instantaneous wind speed signal is greater than the preset wind speed threshold, the controller outputs a voice alarm signal.

[0045] In some optional embodiments, the sensing components may also include a wind speed sensor mounted on the roof. In camping mode, the controller continuously reads the instantaneous wind speed signal output by the wind speed sensor at a preset sampling period, and compares the filtered instantaneous wind speed value with a preset wind speed threshold (e.g., 10.8 m / s). When the instantaneous wind speed value is greater than or equal to the threshold, the controller determines that the current wind force has reached a dangerous level and immediately outputs a voice warning signal. This voice warning signal is broadcast through the speaker of the in-vehicle multimedia system, and the broadcast content may be "The wind is too strong, please be careful." At the same time, the controller displays the warning information on the central control screen and pushes a notification to the user's bound mobile app via T-BOX.

[0046] It should be noted that, by continuously monitoring instantaneous wind speed in camping mode and automatically outputting a voice alarm signal when the wind speed exceeds a threshold, this embodiment of the application can proactively remind users as soon as the wind speed reaches a dangerous level, thereby significantly improving the safety of use in camping scenarios.

[0047] The multi-functional control method for the panoramic sunroof of an MPV vehicle according to embodiments of this application has been described above. It can be recognized that embodiments of this application have the following advantages: 1. Based on rainfall signals, user intention to get out of the vehicle prediction signals, and door opening angle, determine whether it is raining and whether the user intends to get out of the vehicle, and then automatically control the vehicle's sunroof to extend to the target travel position without the need for manual operation by the user; and when the user triggers the camping activation signal, it can be fully extended as a sunroof, eliminating the need to carry additional camping equipment, saving interior space, reducing travel costs, and meeting the one-stop rain shelter and camping needs of MPV users.

[0048] Second, by using weighted fusion to quantify the intention to get off the vehicle, it is possible to avoid false triggering caused by users simply unfastening their seatbelts to rest or accidentally touching the door. Even if a single sensor fails, the intention to get off the vehicle can still be predicted normally. Furthermore, the sunroof can be pre-extended before the door is opened, achieving synchronization between sunroof rain protection and passenger disembarkation.

[0049] Third, the priority of manual control is set higher than that of automatic control, which improves the flexibility of use.

[0050] Fourth, in camping mode, it continuously monitors instantaneous wind speed and automatically outputs a voice alarm signal when the wind speed exceeds the threshold. It can proactively remind users as soon as the wind speed reaches a dangerous level, which significantly improves the safety of use in camping scenarios.
