Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0018] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in the embodiments of this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0019] In this article, it is important to understand that any number of elements in the accompanying figures is for illustrative purposes and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0020] Based on the above background description, the following situations also exist in the related technologies: In related technologies, for scenarios where items are forgotten, and for ordinary items without location tracking capabilities, traditional search methods are used to locate and retrieve them. Users calmly recall the last time they used the item (e.g., upon entering a room, after shopping, or where it was placed in their car), checking pockets, bag compartments, shoe cabinets, coffee tables, and other frequently used areas. Then, a path search is performed, carefully searching along the user's route (parking lot → office → store), relying on the clarity of their memory. Alternatively, they can ask others to determine the location, such as fellow travelers, neighbors, property management, or the venue's service desk.

[0021] For communicable personal items such as smart keys, mobile phones, and tablets that can communicate with vehicles, taking smart keys as an example, Bluetooth can be used for location tracking. A Bluetooth receiver is installed on the key, and a mobile app triggers sound or map location. This is suitable for short-range (indoor, parking lot) location tracking scenarios; it becomes ineffective beyond the Bluetooth range (approximately 10–30 meters). Bluetooth 5.1+ supports angle-of-arrival positioning with an accuracy within 1 meter; Bluetooth 6.0's CS technology further improves accuracy to 0.5 meters through phase ranging. All of the above technical solutions involve manual location tracking by the user.

[0022] In related technologies, multiple low-frequency antennas can be used for coordinated automatic positioning. When the driver approaches the driver's door and presses the door handle lock sensor or steps on the brake pedal, the in-vehicle low-frequency chip controls multiple low-frequency antennas to generate a low-frequency magnetic field through electromagnetism. The electronic control unit inside a communicable personal item can detect the strength of the low-frequency magnetic field emitted by the in-vehicle antenna through magnetic field coupling. This magnetic field strength decreases with increasing distance from the low-frequency antenna. The item's positioning is achieved because the magnetic field strength reflects the distance of the test point from the low-frequency antenna.

[0023] After receiving the low-frequency magnetic field from the low-frequency antenna, the communicable personal item will calibrate itself based on the received magnetic field strength and then send a high-frequency data packet (used to provide feedback on the received magnetic field strength) to the vehicle's microcontroller. Since there are multiple low-frequency antennas placed in different locations inside the vehicle, when a location detection is initiated, the low-frequency antennas inside the vehicle will sequentially send low-frequency magnetic fields. After the communicable personal item detects these magnetic fields, it will reply with the corresponding high-frequency data packet. The vehicle's microcontroller can then confirm the location of the lost item based on the received high-frequency data packet.

[0024] After locating communicable personal items, if the user is found to have left the vehicle, the relevant technology will notify the user via the vehicle's instrument panel or central control display that the communicable personal items have been left in the vehicle. However, if the user has already left the vehicle or is in the process of leaving, the audible reminders on the instrument panel or central control display may be easily ignored by the user. Furthermore, the visual reminders on the instrument panel and central control display may be obstructed by obstacles such as seats or doors, preventing the user from receiving the reminder information. As a result, the user may forget the communicable personal items in the vehicle. Therefore, the item forgetting reminder strategy with low perception and blind spots cannot achieve effective reminders, increasing the probability that communicable personal items are left in the vehicle and increasing the risk of vehicle theft.

[0025] The forgotten item notification control method, electronic device, and vehicle provided in this application, after detecting that a user has left the vehicle, locate the communicable personal item according to a preset positioning node to obtain the lost location. When the lost location meets the forgetting conditions, it is determined that the communicable personal item has been forgotten by the user in the vehicle. At this time, a target quadrant where the communicable personal item exists is further determined to indicate the area range where the communicable personal item exists, guiding the user to the search area to retrieve the item. The target notification area also indicates the specific location of the communicable personal item within the search area, guiding the user to the search location to retrieve the item, enabling the user to quickly retrieve the communicable personal item. Based on the lost location and target quadrant, the projection headlights are controlled to provide a forgotten item notification, directly displaying the lost location and target quadrant through the projection headlights, improving user perception and providing a more intuitive notification. While notifying the user that the communicable personal item has been forgotten in the vehicle, the specific location of the communicable personal item in the vehicle is also indicated, making it convenient and quick for the user to find the forgotten communicable personal item in the vehicle, achieving good human-computer interaction and improving the user experience.

[0026] The following describes in detail, with reference to the accompanying drawings, the method for prompting and controlling the forgetting of items provided by the embodiments of this application.

[0027] In some embodiments, such as Figure 1 As shown, a method for prompting and controlling the forgetting of items includes steps 101-104.

[0028] Step 101: In response to the detection of the user leaving the vehicle signal, determine the location of the lost communicable personal item and the target quadrant corresponding to the lost location.

[0029] In some embodiments, determining the location of a lost communicable personal item and the target quadrant corresponding to the lost location includes: The item is located based on preset location nodes to obtain the lost location; In response to the forgetting condition being met at the location of the lost item, the target quadrant containing the communicable personal item is determined based on the node position of the location node and the location of the lost item.

[0030] In practice, communicable personal items are those that can communicate wirelessly with the vehicle and that the user is accustomed to carrying with them when leaving the vehicle, such as smart keys, mobile phones, tablets, and other items that the user is accustomed to carrying with them.

[0031] The system can determine whether a user has left the vehicle based on vehicle status and sensor data. For example, it can combine door status and seatbelt status for basic exit detection. When the current vehicle speed is less than or equal to a preset speed threshold (e.g., 5 km / h) and the vehicle is in a READY state, if the system detects that the driver's side door changes from closed to open (and then back to closed), and the seatbelt changes from fastened to unfastened, the system can determine that the driver has left the vehicle. This is because detecting the driver's side door changing from closed to open (and then back to closed) indicates that the user opened and closed the door in a low-speed or stationary scenario. Simultaneously, if the seatbelt changes from closed to open, it indicates that the user unfastened the seatbelt in a low-speed or stationary state, further verifying that the driver left the seat. At this point, it can be confirmed that the user has left the vehicle.

[0032] Furthermore, sensor signals can be used for further verification. For example, a gravity sensor can be installed under the driver's seat to detect the weight it bears; changes in this weight can further determine whether the driver has left the vehicle. Torque and pressure sensors can also be installed in the steering wheel; the torque sensor monitors for continuous torque input, while the pressure sensor monitors whether the driver's hands have left the steering wheel.

[0033] If the load weight changes from being greater than a preset weight threshold to being less than or equal to the weight threshold, and the first duration for which the load weight is less than the weight threshold is greater than or equal to a preset first duration threshold, then the weight removal condition is determined to be met. If the steering wheel torque changes from being greater than a preset torque threshold to having no torque input (being less than a certain torque value is considered to be having no torque input), and the second duration of no torque input is greater than or equal to a preset second duration threshold, then the torque off-vehicle condition is determined to be met. If the steering wheel pressure changes from being greater than the preset torque threshold to no pressure input (below a certain pressure value can be considered as no pressure input), and the third duration of no pressure input is greater than or equal to the preset third duration threshold, then the pressure off-vehicle condition is determined to be met. If the weight, torque, and pressure conditions for vehicle departure are all met simultaneously, it is determined that the user's departure conditions are met, and a user departure signal is issued.

[0034] If the first duration of the load-bearing weight being less than the weight threshold is greater than or equal to the preset first duration threshold, it indicates that the user has been away from the seat for a long time, rather than a temporary reduction in load-bearing weight caused by actions such as getting up to pick up items. In this case, it can be determined that the user has left the seat and the weight-free condition is met.

[0035] If the second duration of no torque input is greater than or equal to the preset second duration threshold, it means that the user has not turned the steering wheel for a relatively long time, indicating that the user has stopped controlling the steering wheel and is more likely to leave the vehicle. At this point, it can be determined that the user has stopped turning the steering wheel and the torque-based exit condition is met.

[0036] If the third duration of the no-pressure input is greater than or equal to the preset third duration threshold, it means that the user has not held the steering wheel for a relatively long time, indicating that the user has stopped controlling the steering wheel and is more likely to leave the vehicle. At this point, it can be determined that the user has stopped holding the steering wheel and the pressure exit condition is met.

[0037] If the weight, torque, and pressure conditions for leaving the vehicle are all met simultaneously, it indicates that the user has a high probability of having left the vehicle. The user can pass the departure verification, confirm that the conditions for leaving the vehicle are met, and a user departure signal will be issued.

[0038] For more intelligent vehicles, cameras and AI algorithms can be used to verify driver exit behavior. An infrared camera in a visual recognition system captures the driver's face, torso, and other body parts at the driver's location, combined with deep learning-based image recognition technology to determine if the driver is seated. If the driver's face or torso is detected in the infrared image, it indicates the driver has not left the driver's seat, and the driver exit verification has failed, confirming the driver is still in the vehicle. If the driver's face or torso is not detected in the infrared image, and the duration of this absence exceeds a preset fourth time threshold, it indicates the driver has left the driver's seat, and the driver exit verification has passed, confirming the driver has left the vehicle, and a user exit signal is issued.

[0039] Therefore, when a user leaves the vehicle signal, it means that the user has left the vehicle. At this time, it is necessary to first determine whether the communicable personal items have been left in the vehicle. If the driver has taken the communicable personal items with him when leaving the vehicle, there is no need to remind the driver that the communicable personal items have been left behind. Only when the driver leaves the vehicle and the communicable personal items are still in the vehicle should the driver be reminded that the items have been left behind, so that the driver can return to the vehicle to retrieve the communicable personal items after receiving the reminder.

[0040] The following explanation uses a smart key as an example of a communicable personal item. The Passive Entry Passive Start (PEPS) system achieves keyless start through a triple-collaboration of low-frequency wake-up, high-frequency authentication, and location detection. Therefore, for vehicles equipped with a keyless entry and start system, the key's location can be directly located using the system's positioning function.

[0041] Low-frequency chips (operating at frequencies typically 125 kHz or 134.2 kHz) are key components of vehicle electronic systems, playing a central role in keyless entry and start systems. Low-frequency chips work in conjunction with low-frequency antennas to locate objects.

[0042] When a user pulls the door handle or presses the start button, the PEPS main controller transmits low-frequency signals (e.g., low-frequency electromagnetic waves) through low-frequency antennas (125kHz or 134kHz) located in the door / interior of the vehicle. Low-frequency signals have strong penetrating power but short transmission distance (≤2 meters), enabling centimeter-level precise positioning within the vehicle's interior. The key, bound to the vehicle, contains a three-dimensional low-frequency antenna that receives low-frequency signals via electromagnetic induction and generates a microcurrent, activating the passive RFID chip and activating the key. Once activated, the key locates itself by measuring the signal strength of the received low-frequency signal. Simultaneously, the remote key transmits encrypted identity information, including a unique ID and a rolling code, via high-frequency radio frequency signals (433MHz or 434MHz). The vehicle's RF receiver (usually located in the headliner) transmits the signal to the PEPS controller, verifying whether the ID and rolling code match pre-stored data. If a match is found, high-frequency authentication is successful, confirming the key's legitimacy and validally locating the lost location.

[0043] The process of achieving positioning by measuring the signal strength of the received low-frequency signal is as follows: To ensure that the positioning function of the low-frequency antenna is applicable to the item forgetting reminder function, the triangularly set low-frequency antenna in the relevant technology has been modified to a bidirectional symmetrically set low-frequency antenna. The positions of the low-frequency antennas (each low-frequency antenna corresponds to a positioning point) are set as follows: Figure 2 As shown: Two longitudinal positioning nodes, namely positioning node 1 and positioning node 2, are symmetrically set along the length of the vehicle, and two lateral positioning nodes, namely positioning node 3 and positioning node 4, are set along the width of the vehicle. For example, the interior space of the vehicle is abstracted as a rectangular plane. The longitudinal positioning node is set at the midpoint of the lateral side, and the lateral positioning node is set at the midpoint of the longitudinal side. The distance between the two longitudinal positioning nodes is the longitudinal node spacing, which is equal to the length of the longitudinal side. The distance between the two lateral positioning nodes is the lateral node spacing, which is equal to the length of the lateral side. In order to more conveniently represent the position information, the intersection of the line connecting the longitudinal positioning nodes and the line connecting the lateral positioning nodes is determined as the origin. The line connecting the longitudinal positioning nodes is the Y-axis, the line connecting the lateral positioning nodes is the X-axis, the positive Y-axis in the direction of the vehicle's front is the positive X-axis, and the direction of the passenger side is the positive X-axis. A positioning plane coordinate system is constructed.

[0044] The origin point represents the center of the vehicle's interior space. When the horizontal node spacing is equal to the vertical node spacing, the origin point is equidistant from different positioning nodes, indicating the absolute center of the vehicle's interior planar space. It should be noted that abstracting the vehicle's interior space as a rectangular plane is for ease of illustration. In actual use, UI optimization is needed based on the vehicle's interior image and interior space model to achieve a clearer guidance effect.

[0045] In some embodiments, the item is located based on preset positioning nodes to obtain the lost location, including: Determine the communication time between different positioning nodes and communicable personal items; Determine the equivalent distance between communicable personal items and different positioning nodes based on communication time; The location of the lost item is determined based on the equivalent distance between it and different positioning nodes.

[0046] In practice, after the coordinate system is constructed, the control positioning nodes communicate with the communicable personal items sequentially (or simultaneously), and monitor the communication time between each positioning node and the communicable personal items. The equivalent distance corresponding to the communication time is used to determine the location of the lost item. Since the propagation speed of the communication signals of different positioning nodes is the same, there is a corresponding relationship between the communication time and the interval distance. The interval distance corresponding to the communication time can be used, that is, the coordinate system uses time as the unit to determine the location of the lost item.

[0047] Alternatively, the distance between different positioning nodes and the communicable personal item can be directly determined. Then, the item can be located based on the different distances to obtain the corresponding lost location. Specifically, a low-frequency chip controls multiple low-frequency antennas to generate a low-frequency magnetic field through electromagnetism. The electronic control unit inside the communicable personal item can detect the strength of the low-frequency magnetic field emitted by the antenna inside the vehicle through magnetic field coupling. This magnetic field strength decreases with increasing distance from the low-frequency antenna. The item's location is achieved because the magnetic induction strength of the magnetic field reflects the distance of the test point from the low-frequency antenna.

[0048] After receiving the low-frequency magnetic field from the low-frequency antenna, the communicable personal item will calibrate itself based on the received magnetic field strength and then send a high-frequency data packet (used to provide feedback on the received magnetic field strength) to the vehicle's microcontroller. Since there are multiple low-frequency antennas placed in different locations inside the vehicle, when a location detection is initiated, the low-frequency antennas inside the vehicle will sequentially send low-frequency magnetic fields. After the communicable personal item detects these magnetic fields, it will reply with the corresponding high-frequency data packet. The vehicle's microcontroller can then confirm the location of the lost item based on the received high-frequency data packet.

[0049] After determining the location of the lost item, it is determined whether the user left the vehicle and left a communicable personal item inside. In other words, it is determined whether the location meets the criteria for forgetting. The process is shown in the following example: In some embodiments, determining whether the location of the lost item meets the forgetting criteria includes: Since the location where the item was lost exists within the vehicle's interior area, the forgetting condition is determined to be met.

[0050] Since the location where the item was lost exists outside the vehicle, it is determined that the forgetting condition is not met.

[0051] In practice, since the scenario of forgetting a communicable personal item involves the user leaving the vehicle and leaving it inside, the prerequisite for issuing a forgotten item notification is that the communicable personal item is located inside the vehicle. Therefore, the location of the lost item can be used to determine whether it has been forgotten. After detecting the user leaving the vehicle signal, if it is determined that the lost item is located inside the vehicle, it indicates that the user has left the vehicle and the communicable personal item has been left inside the vehicle, meeting the conditions for forgetting a communicable personal item. Therefore, the forgotten item notification is required.

[0052] After detecting the user's departure signal, if it is determined that the lost item is located outside the vehicle, it means that the user has left the vehicle and the user has taken the communicable personal item with them to the area outside the vehicle. This does not meet the condition that the user has forgotten the communicable personal item, so it is determined that the forgetting condition is not met and there is no need to provide a reminder for the forgotten item.

[0053] If the location of the lost item meets the forgetting criteria, it means that a forgetting prompt is needed. At this point, it is necessary to further determine the target quadrant where a communicable personal item exists based on the node location and the location of the lost item, so that the prompting effect of the vehicle lights can be better.

[0054] like Figure 2As shown, the positioning nodes include positioning node 1, positioning node 2, positioning node 3, and positioning node 4. The lost position is represented by (X, Y). When determining the corresponding quadrant, the target quadrant can be determined directly based on the coordinates of the lost position in the positioning coordinate system formed by positioning nodes 1, 2, 3, and 4. Positioning node 4 is located in the positive X-axis direction, and positioning node 1 is located in the positive Y-axis direction. Therefore, the quadrant where the passenger seat is located is the first quadrant, the quadrant where the driver's seat is located is the second quadrant, and the left half of the rear seats... The area where the missing part is located is in the third quadrant, and the area where the right half of the rear seat is located is in the fourth quadrant. According to the quadrant characteristics of the coordinate system, the X-axis coordinate of the coordinate point in the first quadrant is positive and the Y-axis coordinate is positive; the X-axis coordinate of the coordinate point in the second quadrant is negative and the Y-axis coordinate is positive; the X-axis coordinate of the coordinate point in the third quadrant is negative and the Y-axis coordinate is negative; the X-axis coordinate of the coordinate point in the fourth quadrant is positive and the Y-axis coordinate is negative. Therefore, the target quadrant where the missing part is located can be determined directly based on the coordinate (X, Y) values ​​of the missing part.

[0055] For example, if the location where the lost item is located simultaneously satisfies X > 0 and Y > 0, then the X-axis coordinate of the location is positive and the Y-axis coordinate is also positive. The location is in the first quadrant, and the first quadrant is designated as the target quadrant. If the location where the lost item is located simultaneously satisfies X < 0 and Y > 0, then the X-axis coordinate is negative and the Y-axis coordinate is positive. The location is in the second quadrant, and the second quadrant is designated as the target quadrant. If the location where the lost item is located simultaneously satisfies X < 0 and Y < 0, then the X-axis coordinate is negative and the Y-axis coordinate is also negative. The location is in the third quadrant, and the third quadrant is designated as the target quadrant. If the location where the lost item is located simultaneously satisfies X > 0 and Y < 0, then the X-axis coordinate is positive and the Y-axis coordinate is negative. The location is in the fourth quadrant, and the fourth quadrant is designated as the target quadrant.

[0056] Optionally, if the location of the lost object simultaneously satisfies X=0 and Y>0, then the location of the lost object is located on the boundary line between the first quadrant and the second quadrant. In this case, the first quadrant can be determined as the target quadrant, the second quadrant can be determined as the target quadrant, or both the first and second quadrants can be used as the target quadrant.

[0057] If the missing location simultaneously satisfies X=0 and Y<0, then the missing location is located on the boundary line between the third and fourth quadrants. In this case, the third quadrant can be determined as the target quadrant, the fourth quadrant can be determined as the target quadrant, or both the third and fourth quadrants can be used as the target quadrant.

[0058] If the location of the lost object simultaneously satisfies X > 0 and Y = 0, then the location of the lost object is located on the boundary line between the first quadrant and the fourth quadrant. At this time, the first quadrant can be determined as the target quadrant, the fourth quadrant can be determined as the target quadrant, or both the first and fourth quadrants can be used as the target quadrant.

[0059] If the missing location simultaneously satisfies X < 0 and Y = 0, then the missing location is located on the boundary line between the third quadrant and the second quadrant. In this case, the third quadrant can be determined as the target quadrant, the second quadrant can be determined as the target quadrant, or both the third quadrant and the second quadrant can be used as the target quadrant.

[0060] If the location of the lost object simultaneously satisfies X=0 and Y=0, then the location of the lost object is at the origin, and the target quadrant is empty.

[0061] Alternatively, the corresponding target quadrant can be determined without missing location coordinates, as shown in the following example: In some embodiments, determining the target quadrant where a communicable personal item exists based on the node location of the positioning node and the location of the lost item includes: Determine the distance between the location of the lost item and the location of the node; Based on the interval distance, determine the first target node closest to the location of the lost object and the second target node second closest to the location of the lost object; The target quadrant is determined based on the first target node and the second target node.

[0062] In specific implementation, the distance between the lost location and positioning node 1 is determined as the first interval distance, the distance between the lost location and positioning node 2 is determined as the second interval distance, the distance between the lost location and positioning node 3 is determined as the third interval distance, and the distance between the lost location and positioning node 4 is determined as the fourth interval distance. For a coordinate point in the first quadrant, the two nearest positioning nodes to that coordinate point are definitely positioning node 1 and positioning node 4. For a coordinate point in the second quadrant, the two nearest positioning nodes to that coordinate point are definitely positioning node 1 and positioning node 3. For a coordinate point in the third quadrant, the two nearest positioning nodes to that coordinate point are definitely positioning node 3 and positioning node 2. For a coordinate point in the fourth quadrant, the two nearest positioning nodes to that coordinate point are definitely positioning node 2 and positioning node 4. Based on the above distance characteristics, the target quadrant can also be determined based on the two nodes closest to the lost location.

[0063] Specifically, the positioning node corresponding to the smallest interval among multiple interval distances is determined as the first target node, and the positioning node corresponding to the second smallest interval among multiple interval distances is determined as the second target node. Then, the target quadrant is determined based on the first target node and the second target node.

[0064] For example, if the first target node is location node 1 and the second target node is location node 4, or the first target node is location node 4 and the second target node is location node 1, it means that the lost location meets the interval distance characteristics of the first quadrant, and the first quadrant is determined as the target quadrant.

[0065] If the first target node is location node 1 and the second target node is location node 3, or the first target node is location node 3 and the second target node is location node 1, it means that the lost location meets the interval distance characteristics of the second quadrant, and the second quadrant is determined as the target quadrant.

[0066] If the first target node is location node 2 and the second target node is location node 4, or the first target node is location node 4 and the second target node is location node 2, it means that the lost location meets the interval distance characteristics of the fourth quadrant, and the fourth quadrant is determined as the target quadrant.

[0067] If the first target node is location node 2 and the second target node is location node 3, or the first target node is location node 3 and the second target node is location node 2, it means that the lost location meets the interval distance characteristics of the third quadrant, and the third quadrant is determined as the target quadrant.

[0068] Determining the target quadrant can provide regional hints for displaying prompts, reducing the user's search range and improving the effectiveness of prompts.

[0069] Since the user has already left the vehicle, voice or visual prompts via the instrument panel or central control display may not be perceived by the user (in some models with good sound insulation, the prompt sound may not be perceived after the user closes the door). Therefore, this application, while retaining the prompts on the instrument panel and central control display, adds a vehicle headlight projection prompt strategy that is more easily perceived by users outside the vehicle. While notifying the user that a communicable personal item has been left in the vehicle, the projector headlights will project the specific area and location of the communicable personal item inside the vehicle based on the location of the item and the target quadrant. This allows the user to quickly determine the location of the communicable personal item inside the vehicle, avoiding the problem of users knowing that a communicable personal item has been left in the vehicle but being unable to find it immediately. By projecting the prompt to inform the user of the specific area and location of the communicable personal item inside the vehicle, the user can quickly find the forgotten communicable personal item, improving the prompt effect and user experience.

[0070] For example, the projected content of the vehicle's lights, which are controlled according to the location of the lost item and the target quadrant, is as follows: Figure 3As shown, if a communicable personal item is left behind in the driver's seat, and the corresponding target quadrant is the second quadrant, then the second quadrant will be projected and displayed in the corresponding first color (e.g., red), and a certain marker shape (e.g., circle, rhombus, key shape) will be flashed at the location where the item was left behind. The corresponding marker shape will also be projected and displayed in the second color (e.g., green), indicating that the communicable personal item has been left behind at the location where the marker shape is locked. The user can quickly find the forgotten communicable personal item based on the projected content, improving the user experience. The process of informing the user of the specific area and location of the communicable personal item in the vehicle through the projection prompt is shown in steps 102-104.

[0071] Step 102: Determine the target image region corresponding to the target quadrant in the in-vehicle image.

[0072] In practice, the in-vehicle image can be a real-time image of the in-vehicle scene captured in real time, or an abstract image of the in-vehicle layout. This application uses a vehicle with two rows of seats as an example for illustration. Figure 2 As shown, the vehicle includes front seats and rear seats. The front seats include a driver's seat on the left and a front passenger seat on the right. The rear seats are a single, side-by-side arrangement. The target image region corresponding to the target quadrant in the in-vehicle image is determined as shown in the following embodiment.

[0073] In some embodiments, determining a target image region corresponding to a target quadrant in an in-vehicle image includes: Determine the positioning plane coordinate system corresponding to the target quadrant, align the positioning plane coordinate system with the in-vehicle image to obtain an overlapping image; The image region in the overlapping image that corresponds to the target quadrant is determined as the target image region.

[0074] In specific implementation, as follows Figure 2 Taking the in-vehicle image shown as an example, the corresponding positioning plane coordinate system is a plane coordinate system constructed with the longitudinal positioning node connection line as the Y-axis, the lateral positioning node connection line as the X-axis, the positive Y-axis in the direction of the vehicle's front, and the positive X-axis in the direction of the passenger side. After aligning the positioning plane coordinate system with the in-vehicle image, the result is as follows: Figure 4 The overlapping image shown.

[0075] The alignment process is as follows: The width of the in-vehicle image is aligned using the lateral spacing between positioning nodes 3 and 4, with the upper boundary line of the in-vehicle image parallel to the X-axis and passing through positioning node 1, and the lower boundary line of the in-vehicle image parallel to the X-axis and passing through positioning node 2. The length of the in-vehicle image is aligned using the longitudinal spacing between positioning nodes 1 and 2, with the left boundary line of the in-vehicle image parallel to the Y-axis and passing through positioning node 3, and the right boundary line of the in-vehicle image parallel to the Y-axis and passing through positioning node 4. This completes the alignment of the in-vehicle image and the positioning coordinate system, resulting in the corresponding overlay image. To reduce costs, a low-frequency antenna from the keyless start system can be used as a positioning node. Alternatively, a separate positioning antenna can be set as a positioning node.

[0076] In such Figure 4 In the overlaid image shown, if the target quadrant is the first quadrant, the upper right region of the first quadrant is defined as the target image region. This target image region represents the area where a communicable personal item exists, and the difference in the upper right region needs to be displayed when projecting the prompt. If the target quadrant is the second quadrant, the upper left region of the second quadrant is defined as the target image region. This target image region represents the area where a communicable personal item exists, and the difference in the upper left region needs to be displayed when projecting the prompt. If the target quadrant is the third quadrant, the lower left region of the third quadrant is defined as the target image region. This target image region represents the area where a communicable personal item exists, and the difference in the lower left region needs to be displayed when projecting the prompt. If the target quadrant is the fourth quadrant, the lower right region of the fourth quadrant is defined as the target image region. This target image region represents the area where a communicable personal item exists, and the difference in the lower right region needs to be displayed when projecting the prompt.

[0077] If the target quadrant is the fourth and first quadrants, the right half of the area containing the fourth and first quadrants is defined as the target image area. This target image area represents the area where a communicable personal item exists, and the right half of this area needs to be displayed with a difference during projection prompts. If the target quadrant is the second and first quadrants, the upper half of the area containing the second and first quadrants is defined as the target image area. This target image area represents the area where a communicable personal item exists, and the upper half of this area needs to be displayed with a difference during projection prompts. If the target quadrant is the second and third quadrants, the left half of the area containing the second and third quadrants is defined as the target image area. This target image area represents the area where a communicable personal item exists, and the left half of this area needs to be displayed with a difference during projection prompts. If the target quadrant is the third and fourth quadrants, the lower half of the area containing the fourth and third quadrants is defined as the target image area. This target image area represents the area where a communicable personal item exists, and the lower half of this area needs to be displayed with a difference during projection prompts.

[0078] If the target quadrant is empty, no regional differences will be displayed.

[0079] By displaying differences in the target image area, users can be alerted to areas where they have forgotten their communicable personal items, thus reducing the time spent searching for these items and improving the efficiency of the search.

[0080] Step 103: Determine the target hint area based on the location of the lost object and the target image area.

[0081] In practice, even after determining the target image area, the user still cannot know the exact location of the communicable personal item. Therefore, it is necessary to further determine the target prompt area where the communicable personal item exists in the target image area based on the location where it was lost, so that the user can quickly find the communicable personal item. The process of determining the target prompt area is shown in the following embodiment.

[0082] In some embodiments, determining the target hint region based on the location of the lost object and the target image region includes: The target image region is divided into grids to obtain multiple grid regions; Identify at least one target grid region with a missing location among multiple grid regions, and define the region consisting of at least one target grid region as the target hint region.

[0083] In specific implementation, for example, such as Figure 5 As shown, taking the upper left area as the target image region as an example, the target image region is divided into multiple grid regions according to the preset grid spacing. The smaller the grid spacing, the higher the division accuracy and the higher the positioning accuracy. After grid division, the root location (X,Y) determines at least one target grid region where the communicable item is locked. If the minimum distance from the location to the grid line is greater than a preset distance threshold, it is determined that the communicable item is not on the grid line, and the communicable item may only occupy one grid region. If the minimum distance from the location to the grid line is less than the preset distance threshold, it is determined that the communicable item is on the grid line, and the communicable item may occupy two (e.g., in a corner of the grid region), three, or even four (at the intersection of two grid lines) grid regions. The area composed of at least one target grid region is defined as the target indication area. The target indication area identifies the specific location of the communicable item and needs to be specially displayed so that the user can easily perceive the location of the communicable item.

[0084] Step 104: Control the projection lights to provide a reminder of forgotten items based on the target prompt area and the target image area.

[0085] In practice, by specially displaying the target prompt area (e.g., flashing it with a special color) and differentiating the target image area (e.g., displaying it in a color different from other areas), the user is alerted to the area and specific location of their communicable personal belongings. This achieves highly perceptible display prompts, allowing users to quickly realize that their communicable personal belongings have been left in the vehicle and to quickly locate them, thus improving the user experience. The process of prompting users to indicate when items have been forgotten is illustrated in the following embodiment.

[0086] In some embodiments, controlling the projection vehicle lights to provide a notification of forgotten items based on the target prompt area and the target image area includes: Control the projection headlights to display the target image area in the in-vehicle image using a preset first color; Control the projection headlights to flash in a preset second color to display the target prompt area in the target image area; Control the projection headlights to display areas of the in-vehicle image other than the target image area in a preset third color; Among them, the human eye is more sensitive to the second color than to the first color, and the human eye is more sensitive to the first color than to the third color.

[0087] In specific implementation, such as Figure 3 As shown, the projector headlights will display the target image area in the in-vehicle image in a preset first color (e.g., red), indicating to the user that their personal belongings are located in the driver's seat area. Simultaneously, the projector headlights will flash the target indication area in the target image area in a preset second color (e.g., green) to indicate the specific location of the personal belongings to the user.

[0088] At the same time, the projection headlights are controlled to display areas other than the target image area in the in-vehicle image in a preset third color (such as white), prompting the user that there is no need to search for other areas.

[0089] The human eye is more sensitive to the second color than to the first color, and more sensitive to the first color than to the third color. The first color, which has the highest sensitivity, is used to indicate the location of the lost item. The second color, which has a relatively high sensitivity, indicates the area where a communicable personal item is located. The third color, which has the lowest sensitivity, indicates that the user does not need to search the area. This targeted prompting ensures that the user can easily perceive the location of the lost item, making it easier for the user to find the communicable personal item forgotten in the car and improving the user experience.

[0090] In summary, the item forgetting reminder control method provided in this application, after detecting that the user has left the vehicle, controls the projection headlights to remind the user of the forgotten item based on the location and target quadrant of the item being left behind. The location and target quadrant are directly displayed through the projection headlights, improving user awareness and providing a more intuitive reminder. It not only reminds the user that a communicable personal item has been forgotten in the vehicle, but also indicates the specific location of the communicable personal item in the vehicle, making it easier for the user to find the forgotten communicable personal item in the vehicle. This achieves good human-computer interaction and improves the user experience.

[0091] It should be noted that the method in this embodiment can be executed by a single device, such as a computer or server. The method can also be applied in a distributed scenario, where multiple devices cooperate to complete the task.
