Description

Technical Field

[0001] This application relates to vehicle control technology, and more particularly to a control method for vehicle opening and closing components and a vehicle. Background Technology

[0002] For sensor-activated opening of vehicle components (such as tailgate, hood, etc.), solutions based on physical buttons or remote keys require manual operation, which is not convenient enough. Foot-activated sensor solutions not only require the addition of dedicated sensors, leading to increased hardware costs, but are also prone to unstable recognition rates and high false trigger rates due to improper user kicking movements, sensor interference from mud, water, or snow, resulting in a poor user experience. Summary of the Invention

[0003] This application provides a method for controlling vehicle opening and closing components and a vehicle, which can achieve automatic opening of vehicle opening and closing components with low accidental touch and high reliability without increasing additional hardware costs.

[0004] The technical solution of this application embodiment is implemented as follows: This application provides a method for controlling vehicle opening and closing components, the method comprising: When a wireless connection is established between a vehicle and a portable device, the movement information of the portable device relative to a target opening / closing component of the vehicle is acquired; wherein, the target opening / closing component is provided with an activation area and a hysteresis area; the hysteresis area includes the area when the user operates the operable unit of the vehicle to move; the distance between the operable unit and the target opening / closing component is less than a preset threshold. Based on the movement information, the time and location information of the portable device in the activation zone and / or the hysteresis zone are determined; Based on the time information and the location information, the control command for the target opening and closing component is determined.

[0005] This application provides a control method for a vehicle opening / closing component, applied to a portable device, the method comprising: When a wireless connection is established between the portable device and the vehicle, a ranging request signal sent by the vehicle is received; wherein, the target opening / closing part of the vehicle is provided with an activation area and a hysteresis area; the hysteresis area includes the area when the user operates the operable unit of the vehicle to move; the distance between the operable unit and the target opening / closing part is less than a preset threshold. In response to the ranging request signal, a ranging response signal is sent to the vehicle so that the vehicle can obtain the movement information of the portable device relative to the target opening and closing part based on the ranging response signal, and determine the time information and position information of the portable device in the activation area and / or the hysteresis area based on the movement information, and determine the control command of the target opening and closing part based on the time information and the position information.

[0006] This application provides a vehicle, the vehicle comprising: The vehicle body is provided with a target opening / closing component and an operable unit, and the operable unit and the target opening / closing component are arranged adjacent to each other on the vehicle body. Memory is used to store executable instructions or computer programs. The processor, when executing computer-executable instructions or computer programs stored in the memory, implements the vehicle opening and closing component control method provided in the embodiments of this application.

[0007] The embodiments of this application have the following beneficial effects: By establishing a wireless connection between the vehicle and the portable device, the movement information of the portable device relative to the target opening / closing component of the vehicle is acquired. Based on this movement information, the time and position information of the portable device in the activation and / or hysteresis zones are determined. Furthermore, based on this time and position information, the control command for the target opening / closing component is determined. Thus, the entire control process is automatically triggered by the wireless interaction between the vehicle and the portable device, requiring no manual operation from the user. Simultaneously, by introducing a hysteresis zone corresponding to the user's operation of the operable unit, and by combining time and position information, it is possible to effectively distinguish whether the user is operating the operable unit or intentionally opening / closing the target component. This reduces the false triggering rate of the target opening / closing component without adding additional sensor hardware, thereby improving the user experience. Attached Figure Description

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0012] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0013] In the following description, references to "some embodiments," "this embodiment," "this application embodiment," and examples, etc., describe a subset of all possible embodiments. However, it is understood that "some embodiments" may be the same subset or different subset of all possible embodiments and may be combined with each other without conflict.

[0014] The terms "first," "second," and "third" appearing in the embodiments of this application do not have a specific meaning (e.g., there is no order, nor does it indicate a special limitation on the number of devices in the embodiments of this application), but are merely for the purpose of clearly describing the embodiments of this application and do not constitute any limitation on the embodiments of this application. The term "multiple" appearing in the embodiments of this application refers to two or more integers.

[0015] To facilitate understanding of the technical solutions of the embodiments of this application, the relevant technologies or terms of the embodiments of this application are described below. The following related technologies or related terms are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and all of them fall within the protection scope of the embodiments of this application.

[0016] Against the backdrop of rapid development in automotive intelligence and connectivity, enhancing the user's seamless and convenient car-using experience has become a key focus of technological innovation. Digital keys, as a core technology replacing traditional physical keys, are gradually expanding from simple locking and unlocking functions to a wider range of intelligent vehicle control scenarios. Among these, convenient opening of the vehicle's trunk (such as the tailgate and front storage compartment) is one of the scenarios that users frequently use and where there are clear pain points.

[0017] Currently, there are two main types of automatic or sensor-activated trunk opening solutions. First, there's the manual triggering method based on physical buttons or remote keys, requiring explicit tactile input from the user, which lacks convenience. Second, there's the foot-activated sensor mounted on the vehicle bumper, which triggers trunk opening by detecting specific leg and foot movements. However, this solution not only significantly increases hardware costs, but also suffers from unstable recognition rates, false triggers, or response failures due to factors such as sensor installation location, improper user kicking movements, and environmental interference (e.g., mud, snow, etc.), resulting in a poor user experience.

[0018] To address at least one of the aforementioned problems in related technologies, embodiments of this application provide a control method for vehicle opening and closing components. This method effectively distinguishes between a user's genuine intention to open the component and accidental touches such as passing by, reducing the false trigger rate, improving the reliability of vehicle opening and closing components and user experience, and eliminating the need for additional hardware, thus reducing costs. The control method for vehicle opening and closing components provided in this application will be described in detail below with reference to the accompanying drawings.

[0019] Figure 1 This is one of the flowcharts illustrating a control method for a vehicle opening and closing component provided in an embodiment of this application; as shown below. Figure 1 As shown, the method may include the following steps 101 to 103: Step 101: When a wireless connection is established between the vehicle and the portable device, the movement information of the portable device relative to the target opening / closing component of the vehicle is obtained; wherein, the target opening / closing component is provided with an activation area and a hysteresis area; the hysteresis area includes the area when the user operates the operable unit of the vehicle to move; the distance between the operable unit and the target opening / closing component is less than a preset threshold.

[0020] It should be noted that the execution entity of the vehicle opening and closing component control method provided in this application embodiment can be the vehicle's control system or control device, such as the vehicle's Body Domain Controller (BDC). Furthermore, the target opening and closing component of the vehicle can include any one of the following: tailgate, hood, fuel filler cap, charging port cap, power door, and power window.

[0021] It should be noted that portable devices refer to user terminals capable of establishing a wireless communication connection with a vehicle and acting as the object being located, such as digital keys, smartphones, smartwatches, or smart bracelets. Portable devices can support the NearLink protocol, establishing a secure connection and authentication with the vehicle via NearLink technology, and achieving real-time positioning in conjunction with onboard NearLink anchor points, thus providing accurate movement information for sensing the opening and closing of vehicle mechanisms. In practical applications, portable devices require no active user operation; they are simply carried by the user and automatically recognized by the vehicle.

[0022] In some embodiments, when a user brings a bound portable device into the vehicle's communication coverage area, the portable device automatically establishes a connection with the vehicle and performs two-way authentication. After successful authentication, the Body Domain Controller (BDC) acquires positioning measurement information between itself and the portable device, and determines the movement information of the portable device relative to a target opening or closing component of the vehicle based on this positioning measurement information. This positioning process can be performed continuously at a high frequency to ensure the real-time nature of the movement information.

[0023] For example, when a user enters the vehicle's communication coverage area with a bound smartwatch, the smartwatch and vehicle automatically establish a connection and perform two-way authentication. After successful authentication, the BDC obtains the positioning measurement information between the smartwatch and the vehicle, and determines the smartwatch's movement relative to the vehicle's tailgate based on this positioning measurement information.

[0024] It should be noted that motion information refers to motion-related data of the portable device relative to the target opening and closing parts of the vehicle, which may include the real-time position coordinates of the portable device, its speed, direction of movement, and entry / exit events in various areas.

[0025] It should be noted that the activation zone refers to a preset spatial area around the target opening / closing component of the vehicle. When a portable device enters this area and meets preset conditions, the control command for the target opening / closing component is triggered. This area can be set near the opening path of the target opening / closing component to sense the user's intention to approach it. The hysteresis zone is a buffer area away from the target opening / closing component relative to the activation zone, covering the area of ​​activity when the user operates the operable unit. The operable unit refers to other components on the vehicle located near the target opening / closing component that the user may operate. The distance between the operable unit and the target opening / closing component is less than a preset threshold, meaning that they are located in the same area on the vehicle and have a spatial adjacency. The preset threshold can be set according to the actual size and layout of the vehicle, and its specific value depends on the relative position of the target opening / closing component and the operable unit on the vehicle body. For example, when the target opening and closing component is the vehicle tailgate and the operable unit is the charging port cover, both are located in the rear area of ​​the vehicle (the tailgate is located in the center or right rear of the rear, and the charging port cover is located on the left rear or right rear). The straight-line distance between the two is usually in the range of 0.5 meters to 2 meters, and the preset threshold can be set to 2 meters.

[0026] In some embodiments, when the target opening and closing element is the tailgate, the activation area may be located on the right rear side of the vehicle rear (e.g., a rectangular area of ​​approximately 80cm × 80cm), and the hysteresis area may include the area where the charging port cover located on the left rear side of the vehicle rear is moved by the user.

[0027] In some embodiments, a connection is established between the vehicle and the portable device via a StarScan wireless communication protocol. The vehicle is equipped with multiple StarScan anchor points, such as StarScan slave module antennas installed at the four corners of the front and rear bumpers, and a main module installed inside the vehicle. When a user carrying a portable device enters the vehicle's communication coverage area (approximately 20-30 meters), the portable device automatically establishes a StarScan connection with the vehicle's main module and completes two-way authentication. After the connection is established, the multiple StarScan anchor points on the vehicle side communicate with the portable device for ranging. Specifically, each StarScan anchor point sends a ranging request signal to the portable device, and the portable device returns a ranging response signal upon receiving it. The StarScan anchor point calculates the distance between itself and the portable device based on the time difference between sending the request and receiving the response (i.e., the round-trip time). Each anchor point transmits the measured distance value back to the vehicle's Body Domain Controller (BDC). After collecting the distance values ​​transmitted from multiple anchor points, the Body Domain Controller, for example, selects the ranging values ​​of the three anchor points with the smallest distances, and combines them with the preset position coordinates of each anchor point, using the centroid method of triangles to calculate the real-time position coordinates of the portable device relative to the target opening / closing component of the vehicle. By continuously tracking the location of portable devices, the vehicle domain controller can obtain information about the movement of portable devices relative to target opening and closing parts, such as the real-time location trajectory, movement speed, movement direction, time point and duration of entering or leaving each area.

[0028] Step 102: Based on the movement information, determine the time and location information of the portable device in the activation area and / or the hysteresis area.

[0029] It should be noted that time information may include the duration of the portable device's stay in the activation zone and / or lag zone, the time of entry and exit, etc.; location information may include the specific location coordinates of the portable device in the activation zone and / or lag zone or the area range in which it is located.

[0030] In some embodiments, after the vehicle acquires the movement information of the portable device relative to the target opening / closing component, it can match and determine the real-time position of the portable device based on the preset range of the activation zone and hysteresis zone corresponding to the target opening / closing component, and determine the time information of the portable device in each zone. Specifically, the vehicle's control system (such as the Body Domain Controller (BDC)) continuously receives the real-time position information of the portable device (this position information can be coordinates relative to the vehicle or a position state matching a preset zone), and compares this position information with the spatial range of the activation zone and hysteresis zone to determine which zone the portable device is currently in and the switching status between different zones. Based on this, the BDC statistically analyzes the time data of the portable device in each zone to generate time information. For example, when the portable device enters the activation zone, the BDC starts timing and records its continuous dwell time in the activation zone (e.g., 3 seconds); when the portable device enters the hysteresis zone, the BDC similarly records its dwell time in the hysteresis zone (e.g., 5 seconds). Simultaneously, the BDC also records the position coordinates and their changing trajectory of the portable device in each zone to generate position information. For example, BDC can record the specific coordinates of a portable device within the hysteresis zone, determine whether it is close to the operable unit side, and from which direction it enters the activation zone.

[0031] Step 103: Based on the time information and the location information, determine the control command for the target opening / closing component.

[0032] It should be noted that control commands are instructions used to control the target opening and closing parts to perform corresponding actions, such as opening commands.

[0033] In this embodiment, the control command for the target opening / closing component can be determined based on the time and location information determined in step 102. That is, by combining the time and spatial data of the portable device in the active and / or hysteresis zones, and judging according to preset logical rules, the command used to control the target opening / closing component to perform the corresponding action is determined.

[0034] In some embodiments, the BDC determines whether a user intends to open a target opening or closing device based on the time and location information of the portable device in the activation zone. For example, when the portable device enters the activation zone, the BDC determines whether to generate an opening command based on whether the duration of its stay in the activation zone meets a preset condition; if the stay time is insufficient or the portable device leaves the activation zone midway, the BDC will not generate an opening command. Simultaneously, the BDC also combines the time and location information of the portable device in the lag zone to comprehensively determine the user's intent. For example, if the portable device stays in the lag zone for a long time, the BDC can determine that the user may be operating an operable unit (such as a charging port). In this case, even if the portable device subsequently enters the activation zone, the BDC will adopt a more conservative judgment strategy (such as requiring a longer stay in the activation zone before generating an opening command) to avoid false triggering. Conversely, if the portable device only briefly passes through the lag zone before entering the activation zone, the BDC determines that the user intends to open the target opening or closing device and adopts a more sensitive judgment strategy (such as generating an opening command after a shorter stay in the activation zone).

[0035] In some embodiments, after determining that the user intends to open the target opening or closing part based on time and location information, the generated control command can trigger the target opening or closing part to open automatically (such as the tailgate opening automatically). In some embodiments, if it is determined from time and location information that the user has unintentionally opened the device or there is a risk of accidental activation, then no opening command is generated, or an opening prohibition command is generated to keep the target opening / closing component in the closed state.

[0036] In this embodiment, by establishing a wireless connection between the vehicle and the portable device, the movement information of the portable device relative to the target opening / closing component of the vehicle is acquired. Then, based on this movement information, the time and position information of the portable device in the active zone and / or hysteresis zone are determined. Furthermore, based on this time and position information, the control command for the target opening / closing component is determined. Thus, the entire control process is automatically triggered by the wireless interaction between the vehicle and the portable device, requiring no manual operation from the user. Simultaneously, by introducing a hysteresis zone corresponding to the user's operation of the operable unit, and by combining time and position information, it is possible to effectively distinguish whether the user is operating the operable unit or intentionally opening / closing the target component. This reduces the false triggering rate of the target opening / closing component without adding additional sensor hardware, thereby improving the user experience.

[0037] In some embodiments, such as Figure 2 As shown, before step 103, steps 104 and 105 are also included: Step 104: Based on the time information and location information of the portable device in the lag zone, determine the first dwell time of the portable device in the lag zone.

[0038] In this embodiment, the continuous dwell time of the portable device in the hysteresis zone can be extracted and calculated based on the time and location information of the portable device in the hysteresis zone determined in step 102, and recorded as the first dwell time. Specifically, the continuous dwell time in the hysteresis zone can be calculated based on the time points when the portable device enters and leaves the hysteresis zone. For example, when the portable device enters the hysteresis zone from a non-hysteresis zone, the BDC starts timing; when the portable device leaves the hysteresis zone and enters the activation zone or other areas, the BDC stops timing, and the timing result is the first dwell time.

[0039] Step 105: Adjust the control sensitivity of the target opening / closing component according to the first dwell time.

[0040] It should be noted that control sensitivity refers to how sensitive the target open / close mechanism is to user-triggered actions. The higher the control sensitivity, the easier it is for the user to trigger the opening of the target open / close mechanism; the lower the control sensitivity, the longer the user needs to remain in the activation area to trigger the opening.

[0041] In this embodiment, the control sensitivity of the target opening / closing component can be adjusted according to a preset rule based on the first dwell time determined in step 104. Specifically, when the first dwell time is long, it indicates that the user may spend a long time on the operable unit side (such as operating the charging port). In this case, the control sensitivity can be lowered (i.e., the user needs to stay in the activation area for a longer time to trigger the opening), to avoid the user accidentally triggering the target opening / closing component while operating the operable unit. When the first dwell time is short, it indicates that the user may only be passing through the hysteresis area or intentionally moving quickly towards the target opening / closing component. In this case, the control sensitivity can be increased (i.e., the user only needs to stay in the activation area for a short time to trigger the opening), to achieve a rapid response.

[0042] In some embodiments, such as Figure 2 As shown, step 103 may further include step 1031: Step 1031: Determine the control command for the target opening / closing component based on the time information, the position information, and the control sensitivity.

[0043] In this embodiment, the control command for the target opening / closing component can be comprehensively determined based on the time and location information of the portable device in the activation zone and / or hysteresis zone, combined with the adjusted control sensitivity. Specifically, it can be determined whether the portable device is currently in the activation zone based on the time and location information, and the duration of its stay in the activation zone can be determined. Then, the duration of stay is compared with the control sensitivity. If the duration of stay meets the triggering condition corresponding to the control sensitivity, an opening command for opening the target opening / closing component is generated; otherwise, no opening command is generated.

[0044] For example, when the control sensitivity is increased, BDC uses a lower trigger condition (such as triggering when the user stays in the active area for 2 seconds) to achieve a fast response; when the control sensitivity is decreased, BDC uses a higher trigger condition (such as triggering when the user stays in the active area for 5 seconds) to avoid false triggering.

[0045] In some embodiments, the BDC can also determine the movement trend of the portable device based on time and location information. For example, if the portable device moves continuously toward the target opening / closing part after entering the activation zone from the hysteresis zone, and the dwell time meets the triggering condition corresponding to the control sensitivity, the BDC generates an opening command; if the portable device enters the activation zone but subsequently moves away from the target opening / closing part, even if the dwell time meets the triggering condition, the BDC may not generate an opening command to avoid false triggering.

[0046] It is understood that the embodiments of this application determine the first dwell time of the portable device in the hysteresis zone based on the time and location information of the portable device in the hysteresis zone, and then dynamically adjust the control sensitivity of the target opening and closing component according to the first dwell time. Thus, when the user dwells in the hysteresis zone for a longer time, the control sensitivity decreases accordingly, requiring the user to stay in the activation zone for a longer time to trigger the opening command, thereby effectively preventing the user from accidentally touching the target opening and closing component while operating operable units (such as charging ports). When the user dwells in the hysteresis zone for a shorter time, the control sensitivity increases accordingly, allowing the user to trigger the opening command with a shorter dwell time in the activation zone, achieving rapid response. Furthermore, the control command is determined comprehensively based on the time information, location information, and adjusted control sensitivity, making the control decision more accurate.

[0047] In some embodiments, such as Figure 3 As shown, step 105 may further include steps 1051 and 1052: Step 1051: If the first dwell time is greater than the third dwell time threshold, reduce the control sensitivity.

[0048] It should be noted that the third duration threshold is a preset time limit value used to determine whether the user's dwell time in the lag zone has reached the standard of "long-term dwelling". When the first dwell time exceeds the third duration threshold, it indicates that the user has stayed in the lag zone (especially on the side where the operable unit is located) for a relatively long time, and may have engaged in operations on the operable unit (such as plugging or unplugging the charging gun or operating the fuel filler cap). The third duration threshold can be flexibly calibrated based on factors such as actual application scenarios and user habits. For example, in a scenario where the charging port is located on the left rear side of the vehicle, the user's typical dwell time when operating the charging gun is about 3 to 5 seconds. In this case, the third duration threshold can be set to 3 seconds to accurately identify the user's operation behavior on the charging port side. The third duration threshold may be different for different vehicle models or different operable units, and this application embodiment does not specifically limit this.

[0049] It should be noted that reducing control sensitivity means lowering the control sensitivity of the target opening and closing component, which means that the user needs to stay in the activation area for a longer time to trigger the opening command.

[0050] In this embodiment, the first dwell time determined in step 104 can be compared with a third dwell time threshold. When the first dwell time is longer than the third dwell time threshold, it is determined that the user has spent a long time in the hysteresis zone, possibly operating the operable unit. In this case, the control sensitivity of the target opening / closing component can be reduced. Specifically, the control sensitivity can be reduced by increasing the trigger threshold of the activation zone. For example, when the control sensitivity is reduced, the user needs to stay in the activation zone for a longer time (e.g., from 2 seconds to 5 seconds) before the opening command of the target opening / closing component is triggered. In this way, even if the user accidentally enters the activation zone while operating the operable unit, the target opening / closing component will not be easily triggered, thereby effectively avoiding false triggering.

[0051] For example, when the target opening / closing component is the tailgate and the operable unit is the charging port, the user may linger in the lag zone for a relatively long time when plugging or unplugging the charging gun at the charging port side, and then may walk towards the rear of the vehicle. At this time, because the user's first lingering time in the lag zone exceeds the third duration threshold, the system reduces the control sensitivity. Even if the user subsequently enters the activation zone, a longer lingering time in the activation zone is required to trigger the tailgate to open, thus preventing the user from accidentally opening the tailgate due to normal walking during the charging operation.

[0052] Step 1052: If the first dwell time is less than or equal to the third duration threshold, increase the control sensitivity.

[0053] It should be noted that when the first dwell time does not exceed the third dwell time threshold, it indicates that the user's dwell time in the lag zone is short and there is no behavior of operating the operable unit for a long time. At this time, the user may be passing through the lag zone or have a clear intention to open the target opening or closing device.

[0054] In this embodiment, the first dwell time determined in step 104 can be compared with a third dwell time threshold. When the first dwell time is less than or equal to the third dwell time threshold, it is determined that the user has not stayed in the hysteresis zone for a long time and has not engaged in any operation of the operable unit. At this time, the system increases the control sensitivity of the target opening / closing component. Specifically, the control sensitivity can be improved by reducing the trigger threshold of the activation zone. For example, when the control sensitivity is improved, the user can trigger the opening command of the target opening / closing component after a short dwell time in the activation zone (e.g., 2 seconds). In this way, when the user has a clear intention to open, the system can respond quickly, improving convenience.

[0055] For example, when the target opening / closing component is the tailgate, if a user carrying a portable device walks directly from outside the vehicle to the rear, passing through the lag zone but not staying for a long time (such as going directly to the trunk to retrieve items after parking), and the first dwell time is less than or equal to the third dwell time threshold, the system will increase the control sensitivity. The user can trigger the tailgate to open after staying in the activation zone for a shorter time, achieving a fast response and convenient user experience.

[0056] In some embodiments, in step 1031, determining the control command for the target opening / closing component based on the time information, the position information, and the control sensitivity includes: Based on the time information and location information of the portable device in the activation area, the second dwell time of the portable device in the activation area is obtained; Based on the second dwell time and the control sensitivity, the control command for the target opening / closing component is determined.

[0057] In this embodiment, the continuous dwell time of the portable device in the activation area can be determined based on the time and location information of the portable device in the activation area, and recorded as the second dwell time. Specifically, the continuous dwell time in the activation area can be calculated based on the time points when the portable device enters and leaves the activation area. For example, when the portable device enters the activation area from the lag area or other areas, the BDC starts timing; when the portable device leaves the activation area, the BDC stops timing, and the timing result is the second dwell time.

[0058] After determining the second dwell time, it can be compared with the triggering conditions determined based on the adjusted control sensitivity, and the control command for the target opening / closing component can be determined according to the comparison result. Specifically, different triggering conditions correspond to different control sensitivity levels. When the control sensitivity is high, the triggering conditions are more lenient (i.e., the opening command can be triggered as long as the second dwell time reaches a relatively small value), so that the user can respond quickly when the intention is clear; when the control sensitivity is low, the triggering conditions are more stringent (i.e., the opening command can be triggered only when the second dwell time reaches a relatively large value), to avoid accidental triggering by the user when operating the operable unit. The corresponding control command can be generated based on the comparison result between the second dwell time and the triggering conditions corresponding to the control sensitivity. If the second dwell time meets the triggering conditions (such as reaching or exceeding the trigger threshold), an opening command for opening the target opening / closing component is generated; if the second dwell time does not meet the triggering conditions, no opening command is generated (or an opening prohibition command is generated).

[0059] In some embodiments, the control sensitivity includes trigger sensitivity and opening sensitivity; determining the control command for the target opening / closing element based on the second dwell time and the control sensitivity includes: If the second dwell time is greater than the first duration threshold corresponding to the trigger sensitivity, a prompting instruction is generated to prompt the target opening / closing component to open. If the second dwell time is greater than the second duration threshold corresponding to the opening sensitivity, a control command for opening the target opening / closing element is generated.

[0060] It should be noted that trigger sensitivity and activation sensitivity are two components of sensitivity control, corresponding to the prompt triggering phase and the activation triggering phase, respectively. Specifically, a first duration threshold can be set for the trigger sensitivity to control the timing of the prompt command generation; a second duration threshold can be set for the activation sensitivity to control the timing of the activation command generation. The relationship between the first and second duration thresholds can be configured according to the actual application scenario.

[0061] When the first duration threshold is greater than the second duration threshold, the opening command is generated before the prompt command, meaning the target opening / closing component opens directly without any warning prompt, and then a prompt signal is sent to the user after opening. When the first duration threshold is equal to the second duration threshold, the prompt command and the opening command are generated simultaneously, meaning the prompt and opening are executed synchronously. This configuration is suitable for scenarios where a prompt is needed to be sent to the user at the moment of opening. When the first duration threshold is less than the second duration threshold, the prompt command is generated before the opening command, meaning a prompt signal is sent to the user first, and the opening operation is executed only after the user confirms or remains in the area. This configuration provides the user with sufficient warning and reaction time.

[0062] It is understood that the above three configuration methods can be selected and switched based on different application scenarios, user preferences or security requirements, and this application embodiment does not specifically limit them.

[0063] In this embodiment, the control command for the target opening / closing component can be determined based on the second dwell time of the portable device in the activation area and the control sensitivity (including trigger sensitivity and opening sensitivity). Specifically, the second dwell time of the portable device in the activation area can be compared with a first duration threshold corresponding to the trigger sensitivity and a second duration threshold corresponding to the opening sensitivity. When the second dwell time is greater than the first duration threshold, a prompt command is generated to indicate that the target opening / closing component is open. This prompt command can be used to trigger the vehicle to perform corresponding prompt actions, such as controlling the vehicle's taillights to flash, controlling the vehicle's speaker to emit a prompt sound, or sending a notification message to the portable device to inform the user that the target opening / closing component is open. When the second dwell time is greater than the second duration threshold, a control command is generated to open the target opening / closing component, and the target opening / closing component (such as the tailgate) opens automatically.

[0064] For example, when the control sensitivity is increased, both the first duration threshold corresponding to the trigger sensitivity and the second duration threshold corresponding to the activation sensitivity decrease (e.g., the first duration threshold is 1.5 seconds, and the second duration threshold is 3.5 seconds). If the user stays in the activation area for more than 1.5 seconds, a prompt command is triggered; if it stays for more than 3.5 seconds, the target opening / closing component is triggered. When the control sensitivity is decreased, both the first and second duration thresholds increase (e.g., the first duration threshold is 3 seconds, and the second duration threshold is 6 seconds). The user needs to stay in the activation area for a longer period to trigger the prompt and activate the device. The first and second duration thresholds can be dynamically adjusted through the control sensitivity adjustment process described in step 105 above.

[0065] It is understood that the embodiments of this application, by setting control sensitivity including trigger sensitivity and activation sensitivity, and generating prompt instructions and activation instructions based on the comparison results of the second dwell time with the first duration threshold and the second duration threshold respectively, realize a two-level trigger mechanism of prompt and activation, thereby improving the user experience.

[0066] In some embodiments, the operable unit includes a first operable unit and a second operable unit, and the hysteresis region includes a first hysteresis region and a second hysteresis region. The first hysteresis region includes the area when the user operates the first operable unit of the vehicle to move, and the second hysteresis region includes the area when the user operates the second operable unit of the vehicle to move.

[0067] It should be noted that the first operable unit and the second operable unit refer to two different components on the vehicle located near the target opening / closing part, which the user may operate. Correspondingly, the first hysteresis zone includes the area where the user moves when operating the first operable unit, that is, the spatial area where the user may stop or pass through when operating the first operable unit; the second hysteresis zone includes the area where the user moves when operating the second operable unit, that is, the spatial area where the user may stop or pass through when operating the second operable unit. It can be understood that by setting two hysteresis zones corresponding to the two operable units respectively, the behavioral characteristics of the user when operating different operable units can be distinguished more finely, further improving the accuracy of intent recognition.

[0068] For example, when the target opening / closing component is the tailgate of a vehicle, the first operable unit can be the vehicle's charging port cover, and the first hysteresis zone can include the area where the user moves the charging port cover (e.g., the left rear side of the vehicle's rear); the second operable unit can be the vehicle's fuel filler cap, and the second hysteresis zone can include the area where the user moves the fuel filler cap (e.g., the right rear side of the vehicle's rear). When the user operates the charging port cover, the portable device will remain in the first hysteresis zone; when the user operates the fuel filler cap, the portable device will remain in the second hysteresis zone. By distinguishing the different positional and temporal information of the portable device in the first and second hysteresis zones, the system can determine which operable unit the user is specifically operating, thereby more accurately determining whether the user intends to open the tailgate.

[0069] In some embodiments, the first hysteresis zone and the second hysteresis zone may be spatially separated (e.g., located on different sides of the rear of the vehicle) or partially overlap (e.g., when the charging port cover and the fuel filler cover are located on the same side). The positions of the two hysteresis zones can be set according to the actual layout of the operable units on the vehicle, and this application embodiment does not specifically limit this.

[0070] It is understood that the above-described correspondence between operable units and hysteresis zones is merely illustrative, and the number and type of operable units can be adjusted according to different vehicle configurations. This application does not limit the specific number, type, or location of the operable units or the hysteresis zones; those skilled in the art can configure them according to the actual vehicle layout.

[0071] In some embodiments, the control method for vehicle opening and closing components provided in this application further includes one or more of the following configurations: When the target opening and closing component is a tailgate, the first operable unit includes a charging port cover, and the second operable unit includes a refueling port cover. When the target opening and closing component is the front hatch, the first operable unit includes an electric door, and the second operable unit includes an electric window. When the target opening and closing component is a fuel filler cap, the first operable unit includes a tailgate, and the second operable unit includes a charging port cap. When the target opening and closing component is a charging port cover, the first operable unit includes a tailgate, and the second operable unit includes a fuel filler cap. When the target opening and closing component is an electric door, the first operable unit includes an electric window, and the second operable unit includes a front hood. When the target opening / closing component is an electric window, the first operable unit includes an electric door, and the second operable unit includes a hood.

[0072] It should be noted that there is a spatial adjacency between the target opening / closing component and the operable unit. The user may unintentionally trigger the target opening / closing component when operating the operable unit. The combination of the target opening / closing component and the operable unit may vary in different vehicle models. Therefore, it can be configured according to the actual application scenario to ensure that the hysteresis zone can cover the area of ​​activity when the user operates the operable unit.

[0073] In this embodiment, when the target opening / closing component is the tailgate of a vehicle, the first operable unit can be a charging port cover, and the second operable unit can be a fuel filler cap. The charging port cover and fuel filler cap are typically located at the rear of the vehicle (e.g., the left or right rear side), adjacent to the tailgate. When operating the charging port cover or fuel filler cap, the user may linger or move around at the rear of the vehicle, posing a risk of accidentally touching the tailgate. Therefore, this embodiment configures the charging port cover and fuel filler cap as operable units and provides corresponding hysteresis zones on their respective sides, effectively distinguishing whether the user is operating the charging port cover / fuel filler cap or intentionally opening the tailgate.

[0074] When the target opening / closing component is the hood, the first operable unit can be the power door, and the second operable unit can be the power window. The hood is located at the front of the vehicle, while the power door and power window are located on the side of the vehicle. When operating the power door or power window, the user may be moving near the hood, posing a risk of accidentally touching it. Therefore, in this embodiment, the power door and power window are configured as operable units, and corresponding hysteresis zones are provided on their respective sides, effectively distinguishing whether the user is operating the power door / power window or intentionally opening the hood.

[0075] When the target opening / closing component is the fuel filler cap, the first operable unit can be the tailgate, and the second operable unit can be the charging port cap. The fuel filler cap, tailgate, and charging port cap are all located in the rear area of ​​the vehicle. When operating the tailgate or charging port cap, the user may accidentally touch the fuel filler cap. Therefore, in this embodiment, the tailgate and charging port cap are configured as operable units, and corresponding hysteresis zones are provided on their respective sides, which can effectively distinguish whether the user is operating the tailgate / charging port cap or intentionally opening the fuel filler cap.

[0076] When the target opening / closing component is the charging port cover, the first operable unit can be the tailgate, and the second operable unit can be the fuel filler cap. The charging port cover, tailgate, and fuel filler cap are all located in the rear area of ​​the vehicle. When operating the tailgate or fuel filler cap, the user may accidentally touch the charging port cover. Therefore, in this embodiment, the tailgate and fuel filler cap are configured as operable units, and corresponding hysteresis zones are provided on their respective sides, which can effectively distinguish whether the user is operating the tailgate / fuel filler cap or intentionally opening the charging port cover.

[0077] When the target opening / closing component is a power door, the first operable unit can be a power window, and the second operable unit can be the hood. The hood is located at the front of the vehicle, while the power door and power window are located on the side of the vehicle. When a user operates the power window or hood, they may be near the power door, posing a risk of accidentally opening it. Therefore, this embodiment configures the power window and hood as operable units and provides corresponding hysteresis zones on their respective sides, effectively distinguishing whether the user is operating the power window / hood or intentionally opening the power door.

[0078] When the target opening / closing component is a power window, the first operable unit can be the power door, and the second operable unit can be the hood. The hood is located at the front of the vehicle, while the power door and power window are located on the side of the vehicle. When a user operates the power door or hood, they may be near the power window, posing a risk of accidentally opening it. Therefore, this embodiment configures the power door and hood as operable units and provides corresponding hysteresis zones on their respective sides, effectively distinguishing whether the user is operating the power door / hood or intentionally opening the power window.

[0079] It is understood that the above configuration is based on the spatial adjacency between various components on the vehicle and user operating habits. Those skilled in the art can make adaptive adjustments to the above configuration according to the actual layout of different vehicle models (such as the interchange of the positions of the charging port cover and the fuel filler cap, the relative positions of the power windows and power doors, etc.), all of which fall within the protection scope of this application.

[0080] In some embodiments, the target opening / closing element is further provided with a non-control area, which is disposed away from the target opening / closing element relative to the activation area and the hysteresis area; the method further includes: If the target opening / closing component has already performed a sensor-activated opening operation and is in a closed state within a preset vehicle control cycle, and the portable device's third dwell time in the non-controlled area exceeds a fourth duration threshold, then the step of determining the control command for the target opening / closing component based on the time information and the location information is executed.

[0081] It should be noted that the embodiments of this application are different from those of the previous ones. Figure 1 , Figure 2 and Figure 3 The methods shown belong to a parallel branch relationship within the same technical solution; Figure 1 , Figure 2 and Figure 3 The illustration shows the process of triggering the sensor to open for the first time, while the embodiment of this application shows the process of triggering the sensor to open for the second time. That is, after the target opening / closing component has been opened and closed by the sensor within a preset vehicle control cycle, it is necessary to first verify that the portable device has left the area where the target opening / closing component is located (entering the non-controlled area and staying for more than the fourth time duration threshold) before the step of determining the control command for the target opening / closing component can be executed again. This is to prevent frequent accidental triggering when the user lingers near the target opening / closing component. The two together constitute the complete control logic.

[0082] It should be noted that the non-control zone refers to the peripheral area further away from the target opening / closing component than the activation zone and hysteresis zone. When the portable device is located in the non-control zone, it indicates that the user has moved away from the target opening / closing component. The preset vehicle control cycle refers to the cycle in which a wireless connection is established between the vehicle and the portable device, that is, a complete communication cycle from the establishment of the wireless connection to the disconnection. The inductive opening operation refers to the opening operation automatically triggered by the aforementioned embodiments of this application. The third dwell time refers to the continuous dwell time of the portable device in the non-control zone, used to determine whether the user has truly moved away from the target opening / closing component (rather than just lingering nearby). The fourth duration threshold is a preset time threshold value used to confirm that the user has indeed left the area where the target opening / closing component is located and has remained there for a certain period of time, rather than temporarily leaving and immediately returning. The fourth duration threshold can be adaptively set based on actual applications, and this application embodiment does not specifically limit it. For example, the fourth duration threshold is 5 seconds.

[0083] In this embodiment, the target opening / closing device also has a corresponding non-control zone, which is located away from the target opening / closing device relative to the activation zone and hysteresis zone. That is, the non-control zone is located outside the activation zone and hysteresis zone; the entry of a portable device into the non-control zone indicates that the user has moved away from the area where the target opening / closing device is located. Within a preset vehicle control cycle, if the target opening / closing device has already performed a sensing opening operation and is in a closed state, the system needs to determine whether the user has truly left the area where the target opening / closing device is located. At this time, if the portable device's dwell time in the non-control zone (i.e., the third dwell time) is greater than the fourth dwell time threshold based on the portable device's location information, it indicates that the user has moved away from the area where the target opening / closing device is located and has remained there for a certain period of time. The system can then execute the step of determining the control command for the target opening / closing device based on time and location information again, i.e., allowing a second sensing opening. If a user performs a sensor-activated opening operation and closes the target opening / closing component once, but does not leave the activation area or lingering area (e.g., still lingering near the rear of the vehicle to organize items), the third dwell time does not meet the condition of being greater than the fourth dwell time threshold. The system will not execute the step of determining the control command for the target opening / closing component based on time and location information again, thereby avoiding frequent false triggers caused by the user lingering near the target opening / closing component.

[0084] For example, when the target opening / closing component is the tailgate, after the tailgate is opened and closed once by sensing, if the user lingers near the rear of the vehicle with a portable device to organize items (while the portable device remains in the active or stagnant zone), the system will not trigger the tailgate to open again. Only when the user leaves the rear area with the portable device and enters the non-controlled zone (e.g., walks towards the driver's seat), and remains in the non-controlled zone for more than the fourth duration threshold (e.g., 5 seconds), will the system allow the step of determining the target opening / closing component to be executed again. The tailgate will only be triggered again when the user returns to the active zone. If the wireless connection between the portable device and the vehicle is lost (e.g., the user leaves the vehicle's communication range with their mobile phone), the current vehicle control cycle ends, and a new vehicle control cycle begins after the connection is re-established, unaffected by previous opening records.

[0085] It is understood that, by setting up a non-control zone, and after the target opening / closing component has performed a sensor-activated opening operation and closed within a preset vehicle control cycle, the step of re-executing the control command for determining the target opening / closing component is only allowed if the portable device enters the non-control zone and stays there for more than a fourth duration threshold. This ensures that the user has truly moved away from the area where the target opening / closing component is located before the sensor-activated opening can be triggered again, effectively avoiding frequent false triggering caused by normal activities when the user stays near the target opening / closing component, and improving the reliability and security of the target opening / closing component control.

[0086] Figure 4 This is a fourth flowchart illustrating a control method for a vehicle opening and closing component provided in this application embodiment. This method is applied to portable devices; such as... Figure 4 As shown, the method may include the following steps 401 to 402: Step 401: When a wireless connection is established between the portable device and the vehicle, a ranging request signal sent by the vehicle is received; wherein, the target opening / closing part of the vehicle is provided with an activation area and a hysteresis area; the hysteresis area includes the area when the user operates the operable unit of the vehicle to move; the distance between the operable unit and the target opening / closing part is less than a preset threshold.

[0087] It should be noted that the vehicle opening and closing mechanism control method provided in this application embodiment is executed by a portable device. A portable device refers to a user terminal capable of establishing a wireless communication connection with the vehicle and acting as a location target, such as a digital key, smartphone, smartwatch, or smart bracelet. The portable device can support the NearLink protocol, establishing a secure connection and authentication with the vehicle via NearLink technology, and cooperating with onboard NearLink anchor points to achieve real-time positioning, thereby providing accurate movement information for the sensing and opening of the vehicle's opening and closing mechanism. In practical applications, the portable device requires no active user operation; it only needs to be carried by the user to be automatically recognized by the vehicle.

[0088] It should be noted that the ranging request signal refers to the signal sent by the vehicle (such as the vehicle-mounted satellite anchor point) to the portable device to measure the distance between the two. After the portable device establishes a wireless connection with the vehicle (such as a satellite connection), the satellite anchor point on the vehicle side will send a ranging request signal, and the portable device will receive the signal to prepare for a ranging response.

[0089] In some embodiments, a wireless connection is established between a portable device (such as a user's smartphone) and the vehicle. After the connection is established, the portable device continuously listens for distance measurement request signals sent by the vehicle. The vehicle-mounted wireless anchor points (e.g., slave modules installed at the four corners of the front and rear bumpers) actively send distance measurement request signals to the portable device, which triggers the portable device to return a response signal so that the anchor points can measure the distance between them.

[0090] In some embodiments, two-way authentication can be performed between the vehicle and the portable device before establishing a connection to ensure secure communication. After successful authentication, the vehicle and the portable device maintain a satellite connection, and the portable device enters a ranging-ready state, ready to receive ranging request signals sent by the vehicle.

[0091] It should be noted that the target opening / closing component of the vehicle can include any one of the following: tailgate, hood, fuel filler cap, charging port cap, power doors, and power windows. The activation zone refers to a preset spatial area around the target opening / closing component. When a portable device enters this area and meets preset conditions, the control command for the target opening / closing component is triggered. This area can be located near the opening path of the target opening / closing component to sense the user's intention to approach it. The hysteresis zone is a buffer area relative to the activation zone, located further away from the target opening / closing component, covering the area of ​​activity when the user operates the operable unit. The operable unit refers to other components on the vehicle located near the target opening / closing component that the user may operate. The distance between the operable unit and the target opening / closing component is less than a preset threshold, meaning they are located in the same area on the vehicle and are spatially adjacent. The preset threshold can be set according to the actual size and layout of the vehicle, and its specific value depends on the relative position of the target opening / closing component and the operable unit on the vehicle body. For example, when the target opening and closing component is the vehicle tailgate and the operable unit is the charging port cover, both are located in the rear area of ​​the vehicle (the tailgate is located in the center or right rear of the rear, and the charging port cover is located on the left rear or right rear). The straight-line distance between the two is usually in the range of 0.5 meters to 2 meters, and the preset threshold can be set to 2 meters.

[0092] In some embodiments, when the target opening and closing element is the tailgate, the activation area may be located on the right rear side of the vehicle rear (e.g., a rectangular area of ​​approximately 80cm × 80cm), and the hysteresis area may include the area where the charging port cover located on the left rear side of the vehicle rear is moved by the user.

[0093] Step 402: In response to the ranging request signal, a ranging response signal is sent to the vehicle so that the vehicle can obtain the movement information of the portable device relative to the target opening / closing component based on the ranging response signal, and determine the time information and position information of the portable device in the activation area and / or the hysteresis area based on the movement information, and determine the control command of the target opening / closing component based on the time information and the position information.

[0094] It should be noted that the ranging response signal refers to the response signal returned by the portable device to the vehicle side after receiving the ranging request signal. The vehicle side can calculate the distance value (i.e., ranging value) between the portable device and each star-shaped anchor point based on the time difference between sending the ranging request signal and receiving the ranging response signal (i.e., the round-trip time). Motion information refers to motion-related data of the portable device relative to the target opening / closing component of the vehicle, which may include the portable device's real-time position coordinates, speed, direction of movement, and entry / exit events in each area. The vehicle side can calculate the real-time position of the portable device based on the ranging values ​​of multiple anchor points. For example, by selecting the ranging values ​​of the three anchor points with the smallest distances and combining them with the preset position coordinates of each anchor point, the real-time position coordinates of the portable device relative to the target opening / closing component of the vehicle can be calculated using the triangle centroid method. Through continuous tracking of the portable device's position, the vehicle's domain controller can obtain the portable device's motion information relative to the target opening / closing component, such as the portable device's real-time position trajectory, speed, direction of movement, and the time and duration of entry or exit from each area.

[0095] In some embodiments, after receiving a ranging request signal from the vehicle, the portable device immediately returns a ranging response signal to the vehicle. This response signal may include information such as the portable device's communication identifier and response timestamp, for the vehicle to perform distance measurement. Upon receiving the ranging response signal, the vehicle calculates the distance between the portable device and each star-shaped anchor point based on the time difference between sending the ranging request signal and receiving the ranging response signal (i.e., the round-trip time) and the signal propagation speed. By collecting ranging values ​​returned from multiple star-shaped anchor points (e.g., multiple anchor points distributed at the four corners of the front and rear bumpers), the vehicle can calculate the real-time position coordinates of the portable device relative to the target opening / closing component, thereby obtaining the portable device's movement information (such as position trajectory, movement speed, entry and exit events in various areas, etc.). Based on this movement information, the vehicle can determine the portable device's time and position information in the active zone and / or hysteresis zone. For example, based on the portable device's real-time position coordinates, the vehicle determines whether it has entered the active zone or hysteresis zone, records the entry and exit times, calculates the dwell time in each area (time information), and records its specific position trajectory (position information) in each area. Ultimately, based on time and location information, the vehicle determines the control command (such as an opening command) for the target opening / closing component according to a preset judgment logic.

[0096] In some embodiments, after sending a ranging response signal, the portable device can continue to listen for and respond to subsequent ranging request signals to support the vehicle side in continuously acquiring its location information and making real-time judgments.

[0097] It should be noted that the vehicle determines the time and location information of the portable device in the activation zone and / or hysteresis zone based on the movement information, and then determines the specific implementation of the control command of the target opening and closing part based on the time and location information. This can be referred to the description of the foregoing embodiments, and will not be repeated here.

[0098] It is understood that, in this embodiment of the application, when a wireless connection is established between the portable device and the vehicle, the portable device receives a ranging request signal sent by the vehicle and responds to the ranging request signal by sending a ranging response signal back to the vehicle. This allows the vehicle to obtain the movement information of the portable device relative to the target opening / closing component, and based on this movement information, determines the time and position information of the portable device in the active area and / or hysteresis area. Furthermore, based on this time and position information, the vehicle determines the control command for the target opening / closing component. Thus, the entire control process is automatically triggered by the wireless interaction between the vehicle and the portable device, requiring no manual operation from the user. Simultaneously, by introducing a hysteresis area corresponding to the user's operation of the operable unit, and by combining time and position information, the vehicle can effectively distinguish whether the user is operating the operable unit or intentionally opening the target opening / closing component. This reduces the false triggering rate of the target opening / closing component and improves the user experience without requiring additional sensor hardware.

[0099] The following examples illustrate possible implementation schemes of the vehicle opening and closing component control method described in one or more of the above embodiments.

[0100] Figure 5 This is the fifth flowchart illustrating a control method for vehicle opening and closing components provided in this application embodiment; as shown... Figure 5 As shown, the method includes: Step 1: Define the region.

[0101] In this step, a two-dimensional coordinate system can be established with the center of the vehicle body as the origin, defining the following areas: Activation area, located on the side of the vehicle tailgate (i.e., the target opening / closing component in the above embodiment) (e.g., the right rear side of the vehicle), used to sense and open the vehicle tailgate; First hysteresis area, located on the side of the vehicle charging port cover (i.e., the first operable unit in the above embodiment) (e.g., the left-side sensing hysteresis area at the rear of the vehicle); Second hysteresis area, located on the side of the vehicle fuel filler cap (i.e., the second operable unit in the above embodiment) (e.g., the right-side sensing hysteresis area at the rear of the vehicle); Non-control area, which is the area outside the activation area, the first hysteresis area, and the second hysteresis area within the communication connection range between the vehicle and the portable device (e.g., the communication connection range of approximately 20-30 meters).

[0102] Step 2: Real-time positioning.

[0103] In this step, after the vehicle establishes a connection and completes authentication with the portable device, real-time positioning is enabled. The vehicle domain controller collects distance measurements from multiple onboard satellite navigation anchors (including those installed inside the vehicle and those at the four corners of the front and rear bumpers) to calculate the portable device's position coordinates. For example, the centroid method is used: the distance measurements from the three closest satellite navigation anchors are selected, and combined with their coordinates, three intersecting circles are constructed. The three closest intersection points formed by the pairwise intersections of these three circles constitute a triangle, and the centroid of this triangle is used as the portable device's position coordinates. The calculated position coordinates of the portable device are then matched with the areas defined in step 1.

[0104] Step 3: Determine the hysteresis condition.

[0105] In this step, it is determined whether the following conditions are met: Condition A, the portable device has not triggered the vehicle's tailgate sensor opening operation after establishing a connection with the vehicle; Condition B, the portable device is located in a non-controlled area and stays there for more than 5 seconds (i.e., the fourth duration threshold in the above embodiment). If either Condition A or Condition B is met, proceed to step 4; otherwise, the subsequent tailgate opening process is not triggered. The determination of Condition B is to prevent accidental triggering of the sensor opening tailgate in scenarios such as the user not leaving immediately after opening and closing the tailgate, lingering near the tailgate side, or operating the charging port cover.

[0106] Step 4: Adaptive sensitivity adjustment.

[0107] In this step, it is determined whether the portable device is positioned in the first hysteresis zone and remains there for more than 3 seconds (i.e., the third duration threshold in the above embodiment). If so, it indicates that the user may be operating the charging port cover. The first time threshold (i.e., the first duration threshold in the above embodiment) is set to T2 (a larger value, such as 5 seconds), and the second time threshold (i.e., the second duration threshold in the above embodiment) is set to T2+3s to reduce the sensitivity of the vehicle tailgate opening. Otherwise, the first time threshold is set to T1 (a smaller value, such as 2 seconds), and the second time threshold is set to T1+2s to increase the sensitivity of the vehicle tailgate opening. Among them, T2 is greater than T1.

[0108] It should be noted that if a portable device is detected to have passed through the first hysteresis zone or the second hysteresis zone without pausing significantly before entering the activation area, it is assumed that the user intends to open the vehicle's tailgate. In this case, the first time threshold can be set to T1 and the second time threshold can be set to T1+2s to improve the sensitivity of the vehicle's tailgate opening.

[0109] Step 5: Start execution.

[0110] In this step, when the portable device is located in the activation area and the duration exceeds the first time threshold, the vehicle domain controller issues a taillight flashing command accompanied by a soft prompting sound, providing initial trigger feedback. When the portable device is located in the activation area and the duration exceeds the second time threshold, the vehicle domain controller issues an opening command to the tailgate drive mechanism, the tailgate opens automatically, and the flashing feedback stops. The difference between the first and second time thresholds can be a fixed difference (e.g., 2-3 seconds), i.e., second time threshold = first time threshold + fixed difference, which determines the duration of the prompting signal. The first time threshold is the object of sensitivity adjustment; it is set to a smaller value (e.g., T1) in sensitive scenarios and a larger value (e.g., T2) in default scenarios, where T1 < T2.

[0111] It should be noted that for secondary triggering of the vehicle tailgate, after the tailgate is opened and closed once, the portable device must leave the activation zone, the first hysteresis zone, and the second hysteresis zone, enter the non-control zone and remain there for more than 5 seconds, and then return to the activation zone via the first or second hysteresis zone before the tailgate can be triggered again. Even after this condition is met, the adaptive sensitivity adjustment mechanism in step 4 is still used to dynamically determine the time threshold for secondary opening. This mechanism ensures that the system can effectively distinguish between the user's true intention to open the tailgate and the lingering scenario after opening and closing it, avoiding frequent false triggering of the tailgate.

[0112] Figure 6 This is a schematic diagram of the distribution of regional and vehicle-mounted starlight anchor points provided in an embodiment of this application. In this embodiment, the vehicle tailgate is used as the target opening and closing element. Figure 6 As shown, a two-dimensional coordinate system is established with the vehicle's center as the origin, where the X-axis represents the vehicle's lateral direction and the Y-axis represents its longitudinal direction. The activation area is located on the right rear side of the vehicle's rear (e.g., 0cm to 80cm on the X-axis, -280cm to -360cm on the Y-axis), which is the core area for the vehicle's tailgate sensor to open. The first hysteresis area is located on the left rear side of the vehicle's rear (e.g., -150cm to 0cm on the X-axis, -180cm to -360cm on the Y-axis), i.e., the side where the charging port is located, serving as the left-side sensor hysteresis area. The second hysteresis area is located on the right rear side of the vehicle's rear (e.g., 0cm to 150cm on the X-axis, -180cm to -360cm on the Y-axis), serving as the right-side sensor hysteresis area. The non-control area is within the StarFlash communication connection range (approximately 20-30 meters from the vehicle's boundary), encompassing all areas other than the activation area, the first hysteresis area, and the second hysteresis area. Figure 6 The document also shows a vehicle-mounted satellite anchor point installed at the center of the vehicle body for establishing a connection and managing communication with the portable device, and vehicle-mounted satellite anchor points distributed at the four corners of the front and rear bumpers of the vehicle body for communicating with the portable device and obtaining distance information between the vehicle-mounted satellite anchor points and the portable device, so as to jointly achieve real-time positioning of the portable device.

[0113] It should be noted that the vehicle can be configured with multiple on-board satellite navigation anchors, such as one anchor at each of the four corners of the front and rear bumpers (a total of four). Additionally, a master control anchor can be installed inside the vehicle for connection management. Each on-board satellite navigation anchor establishes a satellite communication connection with a user-carried portable device (such as a smartphone) and measures the distance between itself and the device in real time. Specifically, each on-board satellite navigation anchor sends a ranging request signal to the portable device via the satellite navigation protocol. Upon receiving the signal, the portable device returns a response signal. The on-board satellite navigation anchor calculates the distance to the portable device based on technologies such as Time of Flight (ToF) or Angle of Arrival (AoA). Each on-board satellite navigation anchor transmits the measured distance information back to the Body Domain Controller (BDC) to provide a reliable basis for subsequent area determination.

[0114] In some embodiments, after acquiring the distance information between multiple vehicle-mounted satellite navigation anchors (e.g., four anchors installed at the four corners of the vehicle's front and rear bumpers) and the portable device, the Body Domain Controller (BDC) sorts the anchors according to their distance values ​​from smallest to largest, and selects the three anchors with the smallest distance values ​​as the anchors to participate in the positioning calculation. For example, if the distance values ​​measured by the four anchors installed at the four corners of the vehicle's front and rear bumpers are: left front anchor 8 meters, right front anchor 7.5 meters, left rear anchor 2.5 meters, and right rear anchor 2.2 meters, then the three closest anchors are the left rear anchor, right rear anchor, and right front anchor. After selecting the three closest anchors, the BDC acquires the known position coordinates of these three anchors pre-stored on the vehicle (e.g., coordinates in a two-dimensional coordinate system with the vehicle's center as the origin), and combines this with the distance values ​​between these three anchors and the target key, using the centroid method of triangles to calculate the real-time position coordinates of the target key.

[0115] It should be noted that other positioning algorithms (such as least squares method, weighted centroid method, etc.) can also be used in practical applications, as long as the location coordinates of the portable device can be calculated based on the distance information measured by multiple vehicle-mounted satellite anchor points.

[0116] In this embodiment, by selecting the three closest vehicle-mounted satellite flash anchor points and using the triangle centroid method to calculate the position coordinates of the portable device, the impact of measurement errors of distant vehicle-mounted satellite flash anchor points on positioning accuracy can be effectively reduced. The triangle centroid method can obtain a relatively accurate position estimate by constructing a triangle and finding its centroid, thereby providing a high-precision position judgment basis for the sensing and opening of the target opening and closing parts, further reducing the risk of false triggering or missed triggering caused by positioning deviation.

[0117] It should be noted that StarFlash technology, as a new generation of short-range wireless communication standard, possesses excellent characteristics such as high precision, high reliability, low latency, high concurrency, high security, and low power consumption, and has been successfully applied in the field of automotive digital keys. This application extends StarFlash's precise positioning capabilities to the scenario of automatic tailgate opening. An adaptive sensitivity adjustment mechanism is designed for typical accidental touch scenarios such as charging operations, and combined with positioning area hysteresis strategies, light and sound prompts, etc., effectively solving the pain points of high false trigger rate and poor reliability of traditional solutions. Compared with existing button or App opening methods, this application achieves truly seamless operation, completely freeing the user's hands in scenarios such as carrying items or holding a baby. Compared with foot-activated solutions, this application does not require additional dedicated sensors, fully reusing the digital key positioning system. Hardware costs can be reduced through algorithm upgrades, while avoiding sensor failures caused by environmental interference or improper actions. Therefore, it provides a highly reliable, low-false-touch, and practically implementable intelligent vehicle tailgate opening solution, achieving full-scenario coverage of "seamless passage" and significantly improving the user's intelligent vehicle experience.

[0118] It should be noted that although the steps of the method in this application are described in a specific order in the accompanying drawings, this does not require or imply that the steps must be performed in that specific order, or that all the steps shown must be performed to achieve the desired result. Additional or alternative steps may be omitted, multiple steps may be combined into one step, and / or one step may be broken down into multiple steps; or steps from different embodiments may be combined into a new technical solution.
