[0002] With the development of intelligent vehicles and the increasing demand for user experience, vehicles equipped with sensor-activated power tailgates are becoming increasingly common.

[0003] In related technologies, sensors (such as capacitive or radar sensors) can be installed at the rear of the vehicle (such as below the rear bumper). When the sensor detects a specific action performed by the user in the sensing area (such as quickly pulling away after the lower leg approaches), the tailgate will open automatically.

[0004] However, in order to avoid accidental opening of the tailgate, the sensing area in the above-mentioned technical solutions is usually hidden or requires special triggering actions, which may cause users to not be able to find the location of the sensing area or to perform the actions incorrectly, resulting in the tailgate being unable to open.

[0027] It should be understood that although the terms first, second, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. Depending on the context, the word "if" as used herein can be interpreted as "when," "when," or "in response to determination."

[0028] Please refer to Figure 1 This diagram illustrates the architecture of a vehicle tailgate control system provided in an exemplary embodiment of this application. This control system can be implemented as an architecture for a configuration system of a vehicle tailgate control method. Figure 1 As shown, the system may include: a vehicle domain controller 101, a Passive Entry Passive Start (PEPS) system 102, a projection light module 103, a taillight module 104, a sound playback module 105, a tailgate drive module 106, a smart device 107, and a tailgate actuator 108.

[0029] The vehicle body domain controller 101 is the core of the vehicle tailgate control system. It interacts with the PEPS 102, projection lamp module 103, taillight module 104, sound playback module 105, and tailgate drive module 106 to process signals, perform logical judgments, and issue control commands. The tailgate drive module 106 is controlled by the vehicle body domain controller 101 and is used to control the tailgate actuator 108 to automatically open and close the tailgate.

[0030] Optionally, PEPS 102 can be integrated into the vehicle domain controller 101, or it can be independent of the vehicle domain controller 101. PEPS 102 is used to detect whether a legitimate smart device 107 has entered a preset range at the rear of the vehicle.

[0031] The smart device 107 is bound to the vehicle, and users can unlock, start, lock, and exit the vehicle by performing specified trigger operations on the smart device 107. The vehicle's body domain controller 101 can obtain the location of the smart device 107 through interaction with the PEPS 102, and the vehicle's body domain controller 101 can send control commands to the smart device 107 through interaction with the PEPS 102 to achieve specified functions (such as displaying specified text, vibration, etc.). The smart device 107 includes, but is not limited to, smart car keys, mobile terminal devices, smart wearable devices, or other devices, and this application does not limit this.

[0032] Please refer to Figure 2 The diagram illustrates a flowchart of a vehicle tailgate control method provided in an exemplary embodiment of this application. This method is applied to vehicles equipped with a sensor-activated electric tailgate, i.e., vehicles with contactless tailgate opening functionality. The method is executed by the vehicle's body domain controller; optionally, the body domain controller may be... Figure 1 The system shown includes the vehicle domain controller 101. For example... Figure 2 As shown, the method may include steps 210 to 230.

[0033] Step 210: When the smart device bound to the vehicle is in the first area, send out the first message; the first area is the area where the distance between the device and the rear of the vehicle is less than a first value, and the first message is used to guide the user into the second area.

[0034] In this embodiment of the application, the smart device bound to the vehicle is a smart device that the user can carry with them and that is authorized by the vehicle. By detecting the location information of the smart device, the user's location information can be obtained, ensuring the legality and security of the tailgate control.

[0035] In some embodiments, the smart device may be equipped with an opening entrance for the contactless tailgate opening function. The user can activate the contactless tailgate opening function by triggering this opening entrance. At this time, the vehicle domain controller can continuously acquire the location information of the smart device. That is, before step 210, the above-mentioned vehicle tailgate control method further includes: acquiring the location information of the smart device when the contactless tailgate opening function is enabled.

[0036] Optionally, the smart device includes at least one of a smart car key, a mobile terminal device, and a smart wearable device. The smart car key can be a physical smart key issued by PEPS, including electronic car keys, remote car keys, etc. The smart car key embeds a low-frequency receiving and high-frequency transmitting module for Radio Frequency Identification (RFID). PEPS compares the smart car key's low-frequency field strength parameters with pre-calibrated parameters, using the real-time detected field strength comparison results to pinpoint the smart car key's location, thus obtaining its location information, and then sending this information to the vehicle domain controller. Optionally, the smart car key can also have a built-in vibration generator and vibration motor to enable vibration functionality; or it can be equipped with a display screen to enable text display functionality. Among them, mobile terminal devices can be smartphones, tablets, laptops, etc., and smart wearable devices can be smartwatches, smart bracelets, smart glasses, etc. The mobile terminal devices and smart wearable devices are connected to the vehicle through vehicle networking or short-range wireless communication technology. Short-range wireless communication technology includes Bluetooth, Wi-Fi, ZigBee, Near Field Communication (NFC), Ultra Wide Band (UWB), etc.

[0037] In some embodiments, the first information is interactive information used to instruct the user that they need to enter a second area before they can open the vehicle's tailgate contactlessly. Optionally, the vehicle's body domain controller can control the vehicle itself to issue the first information, or the vehicle's body domain controller can control a smart device bound to the vehicle to issue the first information. Optionally, the first information can be visual information (including text information, image information), tactile information, auditory information, or other information that the user can perceive; this application does not limit this.

[0038] In some embodiments, the first message is cancelled if the smart device is not in the first area (i.e., has left the first area) and / or has not entered the second area within the first time period (i.e., has not entered the second area within the time limit). The start time of the first time period can be the start time of sending the first message, or the start time of the smart device being in the first area; the end time or duration of the first time period can be predefined by the developer, or customized by the user according to actual needs, or multiple options for the end time or duration of the first time period can be predefined by the developer, with the user selecting one option during actual use.

[0039] Step 220: When the smart device is in the second area, send out the second message; the second area is the area where the distance between the device and the rear of the vehicle is less than a second value, the second value is less than the first value, and the second message is used to guide the user into the third area.

[0040] In this embodiment of the application, the second region is the region closer to the vehicle within the first region.

[0041] In some embodiments, the second information is interactive information used to instruct the user to open the vehicle's tailgate contactlessly by entering a third area. Optionally, the vehicle's body domain controller can control the vehicle itself to issue the second information, or the vehicle's body domain controller can control a smart device bound to the vehicle to issue the second information. Optionally, the second information can be visual information (including text information, image information), tactile information, auditory information, or other information that the user can perceive; this application does not limit this.

[0042] In some embodiments, step 220 can be implemented by issuing a second message when the smart device enters the second area from an area outside the first area; or by issuing a second message when the smart device moves from the first area to the second area. That is, if a user can directly enter the second area from an area outside the first area, in this case, a second message is issued to guide the user into the third area.

[0043] In some embodiments, the second message is cancelled if the smart device is not in the second area (i.e., has left the second area) and / or has not entered the third area within the second time period (i.e., has not entered the second area within the time limit). The start time of the second time period can be the start time of sending the second message or the start time of the smart device being in the second area. The end time of the second time period or the duration of the specified time period can be predefined by the developer, or customized by the user according to actual needs. Alternatively, the developer can predefine multiple options for the end time of the second time period or the duration of the second time period, with the user selecting one option during actual use.

[0044] In some embodiments, the first area, the second area, and the third area are sensing areas for tailgate control. The second area is the primary sensing area for opening the tailgate, and the third area is the secondary sensing area for opening the tailgate; that is, the first information is used to indicate the primary sensing area for opening the tailgate, and the second information is used to indicate the secondary sensing area for opening the tailgate.

[0045] Step 230: When the smart device is in the third zone, control the tailgate of the vehicle to open; the third zone is the area where the distance between the device and the rear of the vehicle is greater than a third value, and the third value is not less than the second value.

[0046] In this embodiment, step 230 refers to controlling the tailgate to open when the smart device is detected to have moved from the second area to the third area. That is, if the smart device moves from an area other than the second area to the third area, the tailgate is not controlled to open; in other words, if the user directly enters the third area from an area other than the second area, the function of opening the vehicle tailgate without contact cannot be achieved.

[0047] Optionally, the first, second, and third values ​​can be predefined by the developers, or customized by the user according to actual needs. Alternatively, the developers can predefine multiple options for the first and second values, with the user selecting one during actual use. In other words, the aforementioned first, second, and third areas can be set by the developers or defined by the user. For example, the first value could be 1.5 meters, 1.6 meters, etc., the second value could be 0.5 meters, 0.6 meters, etc., and the third value could be 0.5 meters, 1 meter, etc. It should be noted that the third area is located within a safe zone outside the tailgate opening area. The tailgate opening area is the zone where the distance between the tailgate and the rear of the vehicle is greater than the tailgate opening distance. The tailgate opening distance is the distance between the bottom of the tailgate and the rear of the vehicle when the tailgate is opened to be parallel to the ground. Therefore, the third area is located within the zone where the distance between the tailgate and the rear of the vehicle is greater than the tailgate opening distance, and the third value is not less than the tailgate opening distance.

[0048] Optionally, the conditions for controlling the tailgate opening include a first condition that the smart device is in a first area, a second condition that the smart device is in a second area, and a third condition that the smart device is in a third area. For example, in a scenario where a user wants to open the vehicle's tailgate without contact, the user can bring the smart device close to the vehicle's tailgate. Upon receiving the first information, the user is guided to enter the second area according to the first information, and upon receiving the second information, the user is guided to enter the third area according to the second information, thus opening the vehicle's tailgate without contact.

[0049] The first piece of information can either inform the user that the current operation has met the first condition for opening the tailgate, or guide the user to complete the subsequent operation (i.e., enter the second area) to meet the second condition for opening the tailgate. Similarly, the second piece of information can either inform the user that the current operation has met the second condition for opening the tailgate, or guide the user to complete the subsequent operation (i.e., enter the third area) to meet the third condition for opening the tailgate and trigger its opening.

[0050] Optionally, the first condition is optional, while the second and third conditions are necessary. That is, a user can directly enter the second area from outside the first area. In this case, a second message is sent to guide the user into the third area. For example, in a scenario where a user wants to open the vehicle's tailgate contactlessly, the user can bring a smart device into the second area. Upon receiving the second message, the user can then enter the third area according to the guidance provided, thus opening the vehicle's tailgate contactlessly.

[0051] In some embodiments, the third value is less than the first value; or, the third region is a region whose distance from the rear of the vehicle is less than the first value and greater than the third value.

[0052] In some embodiments, the third value is equal to the second value, that is, the third region is the region whose distance from the rear of the vehicle is greater than the second value; or, the third region is the region whose distance from the rear of the vehicle is less than the first value and greater than the second value, that is, the third region is the region within the first region excluding the second region.

[0053] In some embodiments, when the tailgate is open, if the smart device is not in the first area and the duration of the smart device not being in the first area reaches a specified duration threshold, the tailgate can be controlled to close.

[0054] In summary, the solution presented in this application obtains the user's location information by detecting a smart device bound to the vehicle. When the user is detected to be in a first area far from the rear of the vehicle, the system guides the user to a second area closer to the rear of the vehicle based on the first information. When the user is detected to be in the second area, it can be preliminarily determined that the user intends to open the tailgate. The system then guides the user to a third area outside the second area based on the third information. When the user is detected to have entered the third area, the system can confirm the user's intention to open the tailgate, at which point the tailgate is opened. This application provides a human-vehicle interaction method that pre-sets a first area, a second area, and a third area. The system uses multiple sensing areas and provides step-by-step prompts with first and second information to create a user-perceptible, phased, and multi-step guidance path. This accurately guides the user to enter the sensing areas in sequence, avoiding the problem of the user mislocating the sensing areas. Moreover, the user does not need to make any special movements; by simply moving the smart device at the rear of the vehicle, they can open the tailgate without contact. By detecting the position of the smart device, it can prevent unauthorized users from accidentally opening the tailgate and reduce the difficulty for authorized users to open the tailgate, thereby improving the intuitiveness of user-vehicle interaction and enhancing the convenience and reliability of the contactless tailgate opening function.

[0055] Based on the above Figure 2 Please refer to Figure 3This illustrates a flowchart of a vehicle tailgate control method provided in an exemplary embodiment of this application. Figure 3 As shown, step 220 above can be implemented as step 220a.

[0056] Step 220a: When the smart device is in the second area and the duration of being in the second area reaches the first threshold, send out the second message.

[0057] In other words, the second condition can be further limited to the time the smart device spends in the second area reaching a first threshold, that is, the time the user stays in the second area meets the first threshold.

[0058] In some embodiments, when the smart device is in the second area, the vehicle domain controller starts timing to count the duration the smart device is in the second area, and sends out second information when the duration the smart device is in the second area reaches a first threshold.

[0059] Optionally, the first threshold can be predefined by the developer, or it can be customized by the user according to actual needs. Alternatively, the developer can predefine multiple options for the first threshold, and the user can choose one option during actual use. In other words, the first threshold can be set by the developer or customized by the user. For example, the first threshold could be 2 seconds, 2.5 seconds, etc.

[0060] In the solution shown in the embodiments of this application, the condition for sending the second information is further limited to the duration of the smart device in the second area reaching a first threshold, that is, the duration of the user's stay in the second area meets the first threshold. By using the condition that the duration of the smart device in the second area reaches the first threshold, it can be determined that the user is not just passing through the second area, but intentionally staying in the second area, so as to clarify the user's intention to open the tailgate, thereby reducing the risk of the tailgate being opened accidentally.

[0061] In one possible implementation, step 220 above can also be implemented as follows: when the smart device is in the second area and remains stationary in the second area for a period of time that reaches a first threshold, a second message is sent.

[0062] In other words, the second condition can be further limited to the duration during which the smart device remains stationary within the second area reaches a first threshold, meaning the duration during which the user remains stationary within the second area meets the first threshold. This solution can avoid the risk of incorrect display of the second information and accidental opening of the tailgate due to a user briefly passing through the second area and the duration of their stay in the second area reaching the first threshold.

[0063] In one possible implementation, prior to step 220a, the vehicle tailgate control method further includes: When the smart device is in the second zone, a third message is sent; the third message is used to indicate to the user that they are in the second zone.

[0064] Optionally, the vehicle's body domain controller can control the vehicle itself to send third information, or the vehicle's body domain controller can control a smart device bound to the vehicle to send third information. Optionally, the third information can be visual information (including text information, image information), tactile information, auditory information, or other information that can be perceived by the user, and this application does not limit this.

[0065] In the solution shown in the embodiments of this application, the third information can provide feedback to the user that the user has been detected to be in the second area, providing clear interactive feedback information so that the user can obtain the current status of the vehicle.

[0066] In some embodiments, the third message is cancelled if the smart device is not in the second area (i.e., has left the second area) and / or the duration of being in the second area does not reach the first threshold (i.e., the duration of staying in the second area does not meet the requirement).

[0067] In some embodiments, the third information may also indicate that the time the smart device spends in the second area is being counted or has begun to be counted, that is, instructing the user that a timer is being started or has begun to be counted. Accordingly, upon receiving the third information, the user may remain in the second area to satisfy the condition that the time the smart device spends in the second area reaches a first threshold. Optionally, when the smart device is in the second area, other information may also be sent to indicate that the time the smart device spends in the second area is being counted or has begun to be counted.

[0068] Based on the solutions shown in the above embodiments of this application, in one possible implementation, the vehicle tailgate control method further includes: When the smart device is in the third zone, a fourth message is sent; the fourth message is used to indicate that the tailgate is opening or the tailgate is about to open.

[0069] In some embodiments, the fourth information may also indicate that the contactless tailgate opening operation has been successfully detected. Optionally, if the smart device is in the third area, other information may also be emitted to indicate that the contactless tailgate opening operation has been successfully detected.

[0070] Optionally, the vehicle's body domain controller can control the vehicle itself to send out the fourth information, or the vehicle's body domain controller can control a smart device bound to the vehicle to send out the fourth information. Optionally, the fourth information can be visual information (including text information, image information), tactile information, auditory information, or other information that can be perceived by the user, and this application does not limit this.

[0071] Optionally, if the tailgate is fully open, or if the interaction time for the fourth message has been reached, the fourth message can be cancelled to avoid unnecessary interaction information interfering with the user.

[0072] In the solution shown in the embodiments of this application, the fourth information can provide feedback to the user that the tailgate is opening, providing clear interactive feedback information so that the user can obtain the current status of the vehicle.

[0073] In one possible implementation, step 230 can be implemented as follows: when the smart device is in the third area and the duration of its stay in the third area reaches a second threshold, the tailgate is opened; the issuance of the fourth message when the smart device is in the third area can be implemented as follows: when the smart device is in the third area and the duration of its stay in the third area reaches a second threshold, the fourth message is issued. The second threshold can be the same as or different from the first threshold.

[0074] In other words, the third condition can be further limited to the duration of the smart device's stay in the third area reaching a second threshold, meaning the user's dwell time in the third area meets the second threshold. This solution, by determining that the user is not merely passing through the third area but intentionally staying there, clarifies the user's intent to open the tailgate, thereby reducing the risk of accidental tailgate opening.

[0075] In some embodiments, when the smart device is in the third region, the vehicle domain controller starts timing to count the duration of the smart device in the third region, and when the duration of the smart device in the third region reaches a second threshold, controls the tailgate to open, and / or sends a fourth message.

[0076] Optionally, the second threshold can be predefined by the developer, or it can be customized by the user according to actual needs. Alternatively, the developer can predefine multiple options for the second threshold, and the user can choose one option during actual use. In other words, the aforementioned second threshold can be set by the developer or customized by the user. For example, the second threshold could be 2 seconds, 1.5 seconds, etc.

[0077] In one possible implementation, step 230 can be implemented as follows: when the smart device is in the third area and the duration of its static state within the third area reaches a second threshold, the tailgate is opened; the above-mentioned sending of the fourth message when the smart device is in the third area can be implemented as follows: when the smart device is in the third area and the duration of its static state within the third area reaches a second threshold, the fourth message is sent.

[0078] In other words, the third condition can be further limited to the duration during which the smart device remains stationary within the third area reaches the second threshold, meaning the duration during which the user remains stationary within the third area meets the second threshold. This solution can avoid the risk of the tailgate being accidentally opened due to a user briefly passing through the third area and the duration during that time reaching the second threshold.

[0079] Based on the above Figure 2 Please refer to Figure 4 This illustrates a flowchart of a vehicle tailgate control method provided in an exemplary embodiment of this application. Figure 4 As shown, step 210 can be implemented as step 210a, and step 220 can be implemented as step 220b.

[0080] Step 210a: When the smart device is in the first area, control the designated device to send the first information; the designated device includes at least one of the vehicle's lighting equipment, the vehicle's sound playback equipment, and the smart device.

[0081] In this embodiment, the vehicle's lighting equipment is a device capable of displaying lighting effects to the outside of the vehicle, and the vehicle's sound playback device is a device capable of playing sound to the outside of the vehicle. Optionally, the vehicle's lighting equipment includes, but is not limited to, projection lights and taillights at the rear of the vehicle, and the vehicle's sound playback device includes, but is not limited to, a buzzer and a speaker.

[0082] In some embodiments, the vehicle domain controller can issue a first control command to a designated device when the smart device is in a first area. The first control command is used to instruct the designated device to send a first message.

[0083] Step 220b: When the smart device is in the second area, control the designated device to send the second message.

[0084] In some embodiments, the vehicle domain controller can issue a second control command to a designated device when the smart device is in a second area. The second control command is used to instruct the designated device to send a second message.

[0085] In one possible implementation, sending the third information can be achieved by controlling a designated device to send the third information; sending the fourth information can be achieved by controlling a designated device to send the fourth information.

[0086] In the solution shown in the embodiments of this application, when the vehicle domain controller sends interactive information such as first information and second information, it can control the vehicle's lighting equipment and sound playback equipment to transmit interactive information to the user, and it can also control the smart devices bound to the vehicle to transmit interactive information to the user, thus expanding the diversity of interactive information transmitted by the vehicle to the user.

[0087] Based on the solutions shown in the above embodiments of this application, in order to enable the user to open the vehicle tailgate without contact, the developers can pre-divide sensing areas such as a first area, a second area, and a third area for determining the user's location. Please refer to... Figure 5 This illustrates a schematic diagram of a sensing area provided in an exemplary embodiment of this application. Figure 5 As shown, the first region 501 is the region where the distance to the rear of the vehicle is less than a first value (e.g., 1.5 meters), the second region 502 is the region within the first region 501 where the distance to the rear of the vehicle is less than a second value (e.g., 0.5 meters), and the third region 503 is the region within the first region 501 excluding the second region 502.

[0088] For example, based on the above Figure 1When a user approaches the vehicle with the smart device 107, the vehicle domain controller 101 obtains the distance between the smart device 107 and the rear of the vehicle. When the smart device 107 is in the first area 501, the vehicle domain controller 101 controls the sending of control commands to at least one of the projection light module 103, taillight module 104, sound playback module 105, and smart device 107, so that at least one of the projection light module 103, taillight module 104, sound playback module 105, and smart device 107 emits first information, which is used to guide the user into the second area 502. When the smart device 107 is in the second area 502 ...4, taillight module 105, sound playback module 105, and smart device 107 emits first information, which is used to guide the user into the second area 502. At least one of the following modules—block 103, taillight module 104, sound playback module 105, and smart device 107—issues a third message and starts timing. The third message indicates that the user is in the second area 502. When the smart device 107 is in the second area 502 and the duration of being in the second area 502 reaches a first threshold, the vehicle domain controller 101 sends a control command to at least one of the following modules—projection light module 103, taillight module 104, sound playback module 105, and smart device 107—so that at least one of the following modules—projection light module 103, taillight module 104, sound playback module 105, and smart device 107—issues a second message. The second message guides the user into the third area 503. When the smart device 107 is in the third region 503, the vehicle domain controller 101 sends an opening command to the tailgate drive module 106 to control the tailgate actuator 108 to open the tailgate, and sends control commands to at least one of the projection light module 103, taillight module 104, sound playback module 105, and smart device 107 so that at least one of the projection light module 103, taillight module 104, sound playback module 105, and smart device 107 issues a fourth message, which indicates that the tailgate is opening.

[0089] In one possible implementation, where the designated device includes a lighting device, and the lighting device includes a projection light at the rear of the vehicle, the step 210a above, controlling the designated device to issue the first information, can be implemented as follows: Control the projection light to project a first pattern onto the ground; the first pattern is used to indicate the second area. The control of the designated device to send the second information in step 220b above can be implemented as follows: Control the projector to project a second pattern onto the ground; the second pattern is used to indicate the third area.

[0090] In some embodiments, a projection light at the rear of the vehicle may be mounted below the rear bumper to project a specified pattern onto the ground near the tailgate (e.g., a second area). Accordingly, the projection light may project a first pattern into the second area (e.g., the center point of the second area).

[0091] Please refer to Figure 6 This illustrates a schematic diagram of a projection pattern provided in an exemplary embodiment of this application. Figure 6 As shown in part (a), the projection lamp 601 is centrally mounted below the rear bumper of the vehicle. When the smart device is in the first area, the vehicle domain controller can control the projection lamp 601 to project a first pattern 602 onto the ground. The first pattern 602 is a footprint pattern located in the second area. Figure 6 As shown in part (b), when the smart device is in the first area, the vehicle domain controller can control the projection lamp 601 to project a second pattern 603 on the ground, the second pattern 603 being an arrow pattern pointing to the third area.

[0092] In one possible implementation, the aforementioned control device issuing the third information can be implemented as follows: controlling a projection lamp to project a third pattern onto the ground; the third pattern is used to indicate that the user is in the second area, and / or is counting or has begun counting the duration the smart device has been in the second area. Optionally, the third pattern can be a clock pattern located in the second area, or it can be a flashing second pattern.

[0093] In one possible implementation, the aforementioned issuance of the fourth information can be achieved by controlling a designated device to issue the fourth information, which can be achieved by controlling a projection lamp to project a fourth pattern on the ground. The fourth pattern is used to indicate that the tailgate is opening or the tailgate is about to open, and / or that the contactless tailgate opening operation has been successfully sensed. Based on the above... Figure 6 ,like Figure 7 As shown, when the smart device is in the third area, the vehicle domain controller can control the projection lamp 601 to project a fourth pattern 604 on the ground. The fourth pattern 604 is a checkmark pattern located in the second area.

[0094] In some embodiments, the first pattern, second pattern, third pattern, and fourth pattern described above may be predefined by the developer, or customized by the user according to actual needs. Alternatively, the developer may predefine multiple options for the first pattern, second pattern, third pattern, and fourth pattern, and the user may select one option to determine the pattern during actual use.

[0095] The solution illustrated in this application transforms abstract sensor signals into an intuitive visual language. The projected pattern serves as the human-vehicle interaction interface. By controlling the changes in the projected pattern, the vehicle can transmit commands and provide status feedback to the user, achieving a leap from "passive machine recognition" to "active machine guidance." Upon detecting a smart device, instead of waiting for the user to locate the sensing area, the vehicle proactively informs the user of the sensing area's location through a first pattern. The vehicle demonstrates the system's internal judgment process to the user through different projected patterns, eliminating the user's anxiety about whether the vehicle has received the command during operation. This makes human-vehicle communication transparent, intuitive, and imbued with a sense of technology and ritual.

[0096] The solutions shown in the above embodiments of this application can be implemented as a sensor-controlled electric tailgate control system and method based on projection light interaction. Based on the above... Figure 1 Please refer to Figure 8 This illustration shows a schematic diagram of a sensor-controlled electric tailgate system based on projection light interaction, as shown in an exemplary embodiment of this application. Figure 8 As shown, the sensor-controlled electric tailgate system based on projection light interaction includes a smart car key, a gateway, a body domain controller 101, a PEPS 102, a projection light module 103, a tailgate drive module 106, and a tailgate actuator 108. The gateway, acting as the central hub of the vehicle network, is responsible for protocol conversion and data routing, and communicates with the body domain controller 101, PEPS 102, projection light module 103, and tailgate drive module 106 via a Controller Area Network (CAN).

[0097] Based on the above Figure 8 Please refer to Figure 9 This illustration shows a schematic diagram of the arrangement of a sensor-controlled electric tailgate system based on projection light interaction, as shown in an exemplary embodiment of this application. Figure 9 As shown, the sensor-controlled electric tailgate system based on projection light interaction includes PEPS and vehicle antenna system 901, body domain controller and gateway system 902, tailgate drive system and strut and lock system 903, and projection light module 904.

[0098] Among them, the PEPS controller and vehicle antenna system 901, the body domain controller and gateway system 902, and the tailgate drive system and strut and lock system 903 are the original structures of the vehicle. The projection light module 904 is an additional structure of LED projection light installed under the rear bumper of the vehicle. It is controlled by the body domain controller and is used to project preset patterns onto the ground.

[0099] For example, a sensor-controlled electric tailgate control method based on projection light interaction includes: When the vehicle is in a low-power polling state, PEPS continuously monitors the location and status information of the legitimate smart key. When PEPS detects that the smart key is approaching the first area (1.5 meters) at the rear of the vehicle, it sends a status signal to the vehicle control system; the vehicle control system then sends a request signal to the projection light module, requesting that the first pattern (such as...) be illuminated. Figure 6 (As shown in the first pattern 602); the projection lamp module drives the light to illuminate the first pattern; wherein, the first pattern is used to guide the user to the second area to confirm whether the user intends to request the opening of the tailgate; When PEPS detects that the smart car key is close to the second area (0.5 meters) at the rear of the vehicle, it sends a status signal to the vehicle domain control system; the vehicle domain control system sends a request signal to the projection light module, the first pattern projected on the ground by the projection light module begins to flash, the vehicle domain control system receives the PSPE signal and starts timing; Upon receiving the PEPS signal, the vehicle control system determines that the smart key has remained in the second area (0.5 meters) for more than 2 seconds. It then sends a request signal to the projection light module, requesting the illumination of the second pattern (e.g., ...). Figure 6 (As shown in the second pattern 603); wherein, the second pattern is used to confirm the user's intention to open and guide the user to exit to the safe area where the tailgate is open; When PEPS detects that the smart key has left the second area (0.5 meters) and remains within the first area (1.5 meters), the vehicle domain control system sends an opening command to the tailgate drive module, which then opens the power tailgate. Simultaneously, it sends a signal to the projection light module, requesting the projection of a fourth pattern (such as...). Figure 7 (As shown in the fourth pattern 604).

[0100] In other words, the vehicle control system determines this sequence (user approaches → user enters the first area → user enters the second area as prompted → user leaves and retreats to the third area as prompted) as a clear and unambiguous intention to open the tailgate.

[0101] Throughout the process, if the smart car key leaves the detection range, or if the user does not operate as prompted for an extended period of time, the system will automatically reset after a timeout, turn off the projection, and wait for the next trigger.

[0102] In one possible implementation, where the designated device includes lighting equipment, specifically the vehicle's taillights, the step 210a above, controlling the designated device to issue the first message, can be implemented as follows: Control the taillights to illuminate in the first illumination mode; the first illumination mode is used to guide the user into the second area. The control of the designated device to send the second information in step 220b above can be implemented as follows: Control the taillights to illuminate in a second lighting mode; this second lighting mode is used to guide the user into the third area.

[0103] In the embodiments of this application, the second emission mode is different from the first emission mode.

[0104] In some embodiments, the first illumination mode may be that the taillights move back and forth in a low-brightness flowing scan to guide the user's gaze to the area below the rear of the vehicle; the second illumination mode may be that the taillights flash rapidly a specified number of times (e.g., 3 times) to prompt the user to enter a third area.

[0105] In one possible implementation, the aforementioned control device sending the third information can be implemented as follows: controlling the taillights to emit light in a third illumination mode; the third illumination mode is used to indicate that the user is in the second area, and / or, is counting or has begun counting the duration the smart device is in the second area; the third illumination mode is different from the second illumination mode and the first illumination mode. Optionally, the third illumination mode can be that all taillights are lit and maintain high brightness.

[0106] In one possible implementation, the aforementioned control device sends a fourth message, which can be implemented as follows: controlling the taillights to emit light in a fourth illumination mode. This fourth illumination mode indicates that the tailgate is opening or is about to open, and / or that the contactless opening of the tailgate has been successfully detected. The fourth illumination mode is different from the third, second, and first illumination modes. Optionally, the fourth illumination mode can be that the taillights are off or switch to a breathing effect.

[0107] In some embodiments, the first light emission mode, the second light emission mode, the third light emission mode, and the fourth light emission mode can be predefined by the developer, or customized by the user according to actual needs. Alternatively, the developer can predefine multiple options for the first light emission mode, the second light emission mode, the third light emission mode, and the fourth light emission mode, and the user can select one option to determine the mode during actual use.

[0108] In one possible implementation, when the designated device includes a sound device, controlling the designated device to emit the first information in step 210a above can be implemented as follows: The sound device is controlled to emit a first prompt audio; the first prompt audio is used to guide the user into the second area. The control of the designated device to send the second information in step 220b above can be implemented as follows: The control sound device emits a second prompt audio; the second prompt audio is used to guide entry into the third area.

[0109] In the embodiments of this application, the second prompt audio is different from the first prompt audio.

[0110] Alternatively, the sound device can be the vehicle's original buzzer or an added speaker.

[0111] In some embodiments, the first prompt audio, the second prompt audio, and other prompt audio can be pure prompt sounds without semantic information. For example, the first prompt audio can be a short, high-frequency prompt sound (such as "ding ding...ding ding" or "beep beep...beep beep") to guide the user's gaze to the area below the rear of the vehicle, and the sound frequency of the first prompt audio can increase as the user approaches the second area; the second prompt audio can be a low-frequency, slow prompt sound (such as "dong...dong...") to guide the user into the third area.

[0112] In some embodiments, the first prompt audio, the second prompt audio, and other prompt audio can be prompt voices containing semantic information. For example, the first prompt audio can be a prompt voice containing semantics such as "Please enter the second area" or "Please approach the tailgate" to guide the user into the second area; the second prompt audio can be a prompt voice containing semantics such as "Please enter the third area" or "Please move away from the tailgate" to guide the user into the third area.

[0113] In one possible implementation, the aforementioned control of the designated device to issue the third information can be implemented as follows: controlling the audio device to issue a third prompt audio; the third prompt audio is used to indicate that the user is in the second area, and / or, to count or begin counting the duration the smart device has been in the second area, and the third prompt audio is different from the second prompt audio and the first prompt audio. Optionally, the third prompt audio can be a long beep from the audio device (such as a "ding" or "beep" prompt tone), or it can be a prompt voice issued by the audio device containing semantics such as "Please enter the second area" or "Please approach the tailgate".

[0114] In one possible implementation, the aforementioned control device issuing the fourth message can be implemented as follows: controlling the sound device to issue a fourth prompt audio, the fourth prompt audio indicating that the tailgate is opening or is about to open, and / or that the contactless tailgate opening operation has been successfully sensed; the fourth prompt audio is different from the third, second, and first prompt audios. Optionally, the fourth prompt audio can be a cheerful prompt sound (such as "ding-dong," "click," "tick," etc.), or it can be a prompt voice containing semantics such as "Please enter the third area" or "Please stay away from the tailgate."

[0115] In some embodiments, the first, second, third, and fourth prompt audios can be predefined by the developer, or customized by the user according to actual needs. Alternatively, the developer can predefine multiple options for the first, second, third, and fourth prompt audios, and the user can select one option during actual use.

[0116] In one possible implementation, when the designated device includes a smart device, controlling the designated device to issue the first information in step 210a above can be implemented as at least one of the following: The smart device is controlled to display a first prompt text; the first prompt text is used to guide the user to the second area.

The control device displays a second animation; the second animation is used to guide the user into the third area. The control system sends out tactile information based on a second vibration mode; the second vibration mode is different from the first vibration mode.

[0117] In this embodiment of the application, the second prompt text is different from the first prompt text, and the second animation is different from the first animation.

[0118] In some embodiments, the first prompt text may be text such as "Please proceed to the tailgate" or "Please approach the rear of the vehicle" to guide the user into the second area, and the second prompt text may be text such as "Please back away" or "Please move away from the tailgate" to guide the user into the third area.

[0119] In some embodiments, the first vibration mode may be a low-frequency, slow, continuous vibration (e.g., vibrating once per second) to guide the user into the second area; the second vibration mode may be a short, high-frequency, continuous vibration (e.g., vibrating multiple times per second) by the smart device to guide the user into the third area.

[0120] In one possible implementation, the aforementioned control of the designated device to issue third information can be implemented as at least one of the following: Control the smart device to display a third prompt text; the third prompt text is used to indicate that the user is in the second area, and / or is counting or has started counting the duration of the smart device in the second area, and the third prompt text is different from the first prompt text and the second prompt text; The control smart device displays a third animation; the third animation is used to indicate that the user is in the second area, and / or is counting or has begun counting the duration the smart device is in the second area, and the third animation is different from the first animation and the second animation; The control smart device emits tactile information based on a third vibration mode; the third vibration mode is used to indicate that the user is in the second zone, and / or to count or begin counting the duration the smart device is in the second zone, and the third vibration mode is different from the first vibration mode and the second vibration mode.

[0121] Optionally, the third prompt text can be text such as "You have entered the second area" or "Timer is running", and the third vibration mode can be a single vibration lasting for a first specified duration (e.g., 2 seconds).

[0122] In one possible implementation, the aforementioned control device issuing the fourth information can be implemented as at least one of the following: The control device displays a fourth prompt text; the fourth prompt text is used to indicate that the tailgate is opening or the tailgate is about to open, and / or that the contactless opening of the tailgate has been successfully detected, and the fourth prompt text is different from the first prompt text, the second prompt text, and the third prompt text; The control device displays a fourth animation; the fourth animation is used to indicate that the tailgate is opening or the tailgate is about to open, and / or that the contactless tailgate opening operation has been successfully sensed. The fourth animation is different from the first, second, and third animations. The control device emits tactile information based on the fourth vibration mode; the fourth vibration mode is used to indicate that the tailgate is opening or the tailgate is about to open, and / or that the contactless opening of the tailgate has been successfully sensed. The fourth vibration mode is different from the first vibration mode, the second vibration mode, and the third vibration mode.

[0123] Optionally, the fourth prompt text can be text such as "The tailgate is about to open" or "The tailgate is opening," and the fourth vibration mode can be a vibration lasting for a second specified duration (e.g., 1 second), which is different from the first specified duration.

[0124] In some embodiments, the first prompt text, the second prompt text, the third prompt text, and the fourth prompt text may be predefined by the developer, or customized by the user according to actual needs. Alternatively, the developer may predefine multiple options for the first prompt text, the second prompt text, the third prompt text, and the fourth prompt text, and the user may select one option to determine the text during actual use.

[0125] In some embodiments, the first, second, third, and fourth animations can be predefined by the developer, or customized by the user according to actual needs.

[0141] In summary, compared with related technologies, this application has the following beneficial effects: Precise guidance eliminates blind operation: By actively guiding users to the correct position through interactive information such as first information and second information, the problem of users finding the sensing area is completely solved, and the operation is intuitive and clear; Double confirmation greatly reduces false triggering: By combining two actions—instructing the user to enter the second area with first information and instructing the user to leave the second area with second information—and always being associated with the signal of the smart device, a complete intent confirmation chain is formed, which can effectively distinguish between intentional operation and unintentional interference, reducing the false activation rate to an extremely low level. Clear feedback enhances user experience: Every step of the process provides clear interactive information feedback, allowing users to know the current status of the system (identifying, please go back, about to start), resulting in a smooth and technologically advanced human-vehicle interaction experience. High security: It avoids the risk of tailgate collision or loss of property due to accidental opening; The system is simple in structure and easy to implement: it can be upgraded based on the existing electric tailgate and PEPS system, mainly by adding lighting equipment such as projection lamp modules, sound playback equipment such as speaker modules, and optimizing the control logic. The cost increase is limited, but the functional improvement is significant.
