[0002] In the field of modern intelligent vehicles, the interactive experience between vehicles and users has become an important factor in improving the service experience, especially the application of welcome light carpet effects.

[0003] Currently, the welcome light carpet effect, which illuminates the regular welcome light carpet when the vehicle's welcome function is triggered, is mostly fixed content in a fixed position, making it difficult to achieve deep interaction with user behavior and resulting in a monotonous experience. Summary of the Invention

[0004] In view of the above problems, embodiments of the present invention provide a vehicle welcoming method, device, and vehicle to solve the technical problems of the application of welcoming light carpet effects and the inability of users to deeply interact with them in the prior art.

[0007] Based on the real-time location information and the real-time direction of travel, a first projection area is determined among the multiple projection areas used by the vehicle for welcoming guests;

[0008] The first welcoming video corresponding to the first projection area and the real-time direction of travel is determined from the welcoming video set. The welcoming video set includes at least one welcoming video corresponding to different projection areas, and the movement direction of the object in each welcoming video is associated with the user's direction of travel.

[0009] Project the first welcoming video.

The welcoming video set includes at least one welcoming video corresponding to different projection areas, and the movement direction of the object in each welcoming video is associated with the user's travel direction.

[0014] The processing module is used to project the first welcoming video.

[0015] According to another aspect of the present invention, a vehicle is provided, comprising: a processor, a memory, a communication interface, and a communication bus, wherein the processor, the memory, and the communication interface communicate with each other via the communication bus;

[0016] The memory is used to store at least one executable instruction that causes the processor to perform operations such as the vehicle welcoming method described above.

[0037] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0038] In the field of modern intelligent vehicles, the interactive experience between vehicles and users has become a crucial factor in enhancing brand competitiveness and service experience. In particular, interactive welcome light carpet systems enhance the sense of ceremony and fun when users approach the vehicle through real-time interaction between dynamic lighting and user behavior.

[0039] In current technology, welcome light carpet systems typically use fixed-position light projection devices. Their core function is to illuminate the vehicle when the user approaches using preset light patterns (such as static patterns or fixed animations).

[0040] However, the above approach has the following technical problems:

[0041] 1) The welcoming content is monotonous and lacks dynamic interaction: Currently, the lighting or animation mode of the welcoming light carpet is fixed and cannot be adjusted in real time according to the user's specific location, movement direction or behavior changes, which leads to the gradual loss of the sense of ritual in the user experience.

[0042] 2) Lack of high-precision positioning and dynamic content adaptation: Existing technology relies on the low-precision positioning of Bluetooth keys (within a range of about 10 meters), which cannot accurately predict the user's route, and therefore cannot achieve dynamic connection and personalized adaptation of the light projection content.

[0043] 3) Redundancy and low efficiency in video resource storage: The existing system needs to repeatedly store multiple sets of animation files (such as welcoming animations in different directions) in each projection device, resulting in wasted storage space and difficulty in achieving real-time access and dynamic updates of content through centralized control.

[0044] Based on the aforementioned technical problems, the technical concept of this invention is as follows: Given that existing welcome lights on the market display fixed content, users are faced with the same unchanging welcome pattern every time they use their vehicle. This means that the welcome light carpet function only creates a sense of ritual for users in the initial stages of use, and inevitably loses its novelty after a period of time, leading to a decrease in the perceived value of the function over time. Therefore, if the user's position can be located, and the start and end positions of the welcome light illumination (i.e., indicating the current position and direction of travel) can be determined based on the user's position, while simultaneously incorporating interactive content between the user and the welcome lights as the user moves around the vehicle, the welcome process is no longer a fixed sequence. Instead, it projects variable, preset welcome videos onto corresponding projection areas based on real-time location information and real-time direction of travel, thus solving the technical problems existing in the prior art.

[0045] Based on the above technical concept, Figure 1 A schematic diagram of the vehicle welcome system provided by the present invention is shown, as follows: Figure 1 As shown, the vehicle's welcome system includes: terminal equipment, in-vehicle high-precision positioning module, surround view camera, in-vehicle control unit, intelligent cockpit controller, and projection equipment.

[0046] For example, when a user approaches a vehicle with a terminal device, the vehicle's high-precision positioning module obtains the user's location through Bluetooth Low Energy (BLE) negotiation; and the surround-view camera obtains the user's video stream data and sends it to the vehicle control unit. Based on the above, the vehicle control unit determines the control command to wake up the smart cockpit controller. After the user enters the welcoming area, the smart cockpit controller sends an execution command to the projection device. The smart cockpit controller establishes a communication interface with the projection device and sends the corresponding welcoming video to the projection device, thereby realizing the welcoming.

[0047] The above content provides a brief description of the present invention. The following detailed description, through specific embodiments, further illustrates the technical solution of the present invention. The subject of this invention is a vehicle, specifically a controller within the vehicle, such as the vehicle control unit and intelligent cockpit controller in the system example. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0048] Figure 2 A flowchart of a first embodiment of the vehicle welcoming method provided by the present invention is shown, the method being performed by the vehicle. Figure 2 As shown, the method includes the following steps:

[0049] Step 21: Obtain the user's real-time location information and real-time direction of travel;

[0050] In this step, the vehicle obtains the user's current location in real time, which is recorded as real-time location information; and obtains the user's direction of movement, which is recorded as real-time travel direction.

[0051] Optionally, one possible implementation of step 21 could be:

[0052] Step 1: Obtain real-time location information through sensors in the vehicle and / or user equipment;

[0053] In this implementation, the vehicle can interact with the onboard ultra-wideband (UWB) antenna array via pulse signals through the Star Flash Key, calculate distance using time of flight (ToF), measure direction using angle of arrival (AoA), and simultaneously transmit video streams from the surround-view camera to the smart cockpit controller. The user's position is accurately calculated through the images, ultimately obtaining centimeter-level real-time location information.

[0054] Step 2: Obtain the real-time direction of travel based on the user's gait characteristics and real-time location information.

[0055] In this implementation, the inertial measurement unit (IMU) (accelerometer + gyroscope) built into the key detects the user's gait characteristics such as step frequency and turning direction. Combined with the changing trends of high-precision positioning data, the system comprehensively analyzes and judges the user's direction of travel (e.g., approaching the vehicle, moving away from the vehicle, or moving laterally), thereby obtaining the real-time direction of travel.

[0056] Step 22: Based on real-time location information and real-time direction of travel, determine the first projection area among the multiple projection areas used by the vehicle for welcoming guests;

[0057] In this step, based on real-time location information, the user's current projection area can be determined from among multiple projection areas used for welcoming guests, and based on the real-time direction of travel, the projection area the user will reach can be determined.

[0058] Therefore, the projection area determined above can be regarded as the first projection area for subsequent welcoming of guests.

[0059] Optionally, the vehicle includes: at least one array of lights distributed around the vehicle for projecting a welcome video; for each array of lights, the array of lights is used to project the welcome video onto at least one projection area.

[0060] For example, Figure 3 A schematic diagram of the structure of a lamp assembly provided by the present invention is shown, as follows: Figure 3 As shown, the light assembly includes two refracting lenses and one projection lamp.

[0061] Each refracting lens can cover a 45° projection area, and by switching the projection direction, the projected content can cover a 90° area; and to achieve the effect of the projected content covering the area around the vehicle, multiple (e.g., 8) light groups can be arranged throughout the vehicle.

[0062] Right now, Figure 4 A schematic diagram of a lamp assembly layout provided by the present invention is shown, as follows: Figure 4 As shown, the number of light groups can be 8, as indicated by the quarter circle icons in the figure, with each icon representing one light group.

[0063] Correspondingly, Figure 5 A schematic diagram of the projection area provided by the present invention is shown, as follows: Figure 5 As shown, in Figure 4 Based on the 8 light groups shown, there are 16 projection areas, namely 01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11, 12, 13, 14, 15, and 16.

[0064] Optionally, one possible implementation of step 22 could be:

[0065] When the real-time location information is detected to be within the preset sensing area, the first projection area is determined from multiple projection areas based on the real-time location information and the real-time direction of travel.

[0066] In this implementation, when the user's real-time location information is within the preset sensing area, the vehicle's welcoming logic can be triggered, i.e., step 22 and subsequent actions are executed.

[0067] Correspondingly, Figure 6 A schematic diagram of the sensing area provided by the present invention is shown, as follows: Figure 6 As shown, there can be 16 sensing areas. When the user enters the 6th corresponding sensing area, step 22 is executed.

[0068] In practice, step 21 can be executed upon entering any sensing area or step 22 can be started.

[0069] Step 23: Determine the first welcoming video corresponding to the first projection area and the real-time direction of travel from the welcoming video set;

[0070] The welcoming video collection includes at least one welcoming video corresponding to different projection areas, and the movement direction of the object in each welcoming video is associated with the user's walking direction.

[0071] In this step, based on the predefined mapping relationship between travel direction, projection area, and welcome video, suitable video resources can be retrieved from the collection of welcome videos stored in the smart cockpit controller. In each welcome video, the movement direction of objects (which can be dynamic elements, moving targets, etc. in the video, such as the puppy in the attached figure below) is the same as or opposite to the user's travel direction.

[0072] For example, taking the first projection area as any projection area, corresponding to different movement directions (such as A→B, B→A, A→C, C→A, A→D, D→A in Table 1 below); each light group requires image distortion calibration for its two projection areas, requiring a total of 12 welcome videos.

[0073] At this point, based on the user's current location in the first projection area and their real-time direction of travel, the corresponding video number is matched to determine the first welcoming video.

[0074] For example, Figure 7 This invention provides a schematic diagram showing the correspondence between the projection area and the welcoming video. Figure 7 As shown, A, B, C, and D are the user's current locations; Figure 7 It also includes: the current projection area, the left projection area, and the right projection area.

[0075] Table 1 shows a schematic table of the travel direction and playback scene provided by the present invention, as shown in Table 1:

[0076] Table 1

[0077]

[0078] That is, for each projection area, there are different welcoming videos with different directions of travel; and in Table 1, in one implementation, the coverage area of ​​the projection area is the same as that of the sensing area.

[0079] Step 24: Project the first welcoming video.

[0080] In this step, after the first welcoming video is determined as described above, the corresponding light group is controlled to project the first welcoming video.

[0081] Furthermore, the method may also include: stopping the projection of the first welcoming video if the real-time location information indicates that the user leaves the first projection area or enters a vehicle.

[0082] In this implementation, if the real-time location information indicates that the user has left the first projection area or entered a vehicle, the welcoming ceremony is considered to be over. At this time, the departure animation can be played and / or the first welcoming video (light carpet) can be turned off.

[0083] For example, when a user enters or leaves the vehicle, an animation plays of a puppy running from the waiting position toward the vehicle in area 14 and fading out. Then the video transmission stops, and the lights turn off, completing the closed loop of the welcome process.

[0084] For example, Figure 8 This invention provides a schematic diagram of a user leaving the first projection area, as shown in the diagram. Figure 8 As shown, this includes: user and direction of travel.

[0085] When the user is moving in a direction that is far away from the vehicle, the projection of the first welcoming video will stop.

[0086] It should be understood that: Figure 8 , Figure 10 and Figure 11 The example of the puppy in the video is illustrated by the following embodiment involving a welcoming video.

[0087] Optionally, multiple welcome videos from the welcome video collection can be stored in the vehicle's controller.

[0088] In this embodiment of the invention, each light group needs to play 6 video clips (welcome videos). Since a group of lights switches playback areas using a refractive lens, the two projection areas of a single light group require different image distortion calibrations. This results in each light group needing 12 video clips, which would require significant storage space if stored within the light fixture itself.

[0089] At this point, the 12 videos can be stored in the intelligent cockpit controller and called up when this solution is executed.

[0090] For example, one possible implementation of step 24 could be: transmitting the first welcoming video determined in the controller to the first light group corresponding to the first projection area via a communication interface, and controlling the first light group to project the first welcoming video.

[0091] That is, when the vehicle detects the user terminal, the vehicle control unit wakes up the smart cockpit controller in advance. After the user enters the welcome area, the smart cockpit controller sends an execution command to the projection device.

[0092] A communication interface needs to be established between the smart cockpit and the light carpet projection light group. During interaction, the smart cockpit controller transmits video content (e.g., the first welcoming video) in real time to the corresponding light group that needs to perform the projection action (e.g., the first light group). The projection light group receives the content, buffers a few frames, and then begins real-time playback. When the smart cockpit controller stops transmitting video content, the light group immediately stops playing. That is, the content transmission through this interface controls the display or stop of the light group's video. To improve video transmission efficiency, the video content can be transmitted via a video transmission protocol.

[0093] The vehicle welcoming method provided in this invention acquires the user's real-time location information and real-time travel direction; determines a first projection area among multiple projection areas used for welcoming based on the real-time location information and real-time travel direction; determines a first welcoming video corresponding to the first projection area and real-time travel direction from a set of welcoming videos, the set of welcoming videos including at least one welcoming video corresponding to each different projection area, the movement direction of the object in each welcoming video being associated with the user's travel direction; and projects the first welcoming video. This solution, by acquiring and analyzing the user's location and travel direction in real time, can dynamically select the projection area and corresponding welcoming video that best match the current space and movement trend, thereby achieving a highly personalized and precise welcoming experience. This not only enhances the immersiveness and real-time interactivity of the welcoming experience but also avoids projection misalignment or content inconsistency caused by misjudgment of direction or improper area selection, significantly improving user experience and technological perception, while optimizing the directional projection efficiency.

[0094] Figure 9 A flowchart of a second embodiment of the vehicle welcoming method provided by the present invention is shown, the method being performed by the vehicle. Figure 9 As shown, step 22 may include the following steps:

[0095] Step 91: Determine the second projection area where the real-time location information is located among multiple projection areas;

[0096] In this step, the projection area where the user is located, which is consistent with multiple projection areas, is designated as the second projection area based on real-time location information.

[0097] Step 92: If the real-time direction of travel does not point to a projection area adjacent to the second projection area, the second projection area is determined as the first projection area;

[0098] In this step, if the user only stays in the current second projection area, or if the real-time direction of travel does not point to an area adjacent to the second projection area, it is assumed that the user has no need for lateral interaction.

[0099] At this point, the second projection area is designated as the first projection area.

[0100] For example, Figure 10 This invention provides a first schematic diagram illustrating the determination of a first projection area, as shown below. Figure 10 As shown, this includes: user and direction of travel.

[0101] Depend on Figure 10 It can be seen that the user's direction of travel is directly pointing towards the vehicle, that is, only projection area 06 is the second projection area. At this time, projection area 06 is determined as the first projection area.

[0102] That is, when the user enters the projection area 06, the first welcoming video is a puppy running from the car to the device and squatting down.

[0103] Step 93: If the real-time travel direction points to a projection area adjacent to the second projection area, the adjacent projection area and the second projection area are determined as the first projection area.

[0104] In this step, when the user's real-time direction of travel indicates that the user is moving laterally, it is considered that the user has a need for lateral interaction.

[0105] At this point, the current second projection area and the adjacent area of ​​the second projection area are simultaneously determined as the first projection area.

[0106] For example, Figure 11 A second schematic diagram illustrating the determination of the first projection area provided by the present invention is shown, as follows: Figure 11 As shown, this includes: user and direction of travel.

[0107] Depend on Figure 11 It can be seen that the user's direction of travel is directly pointing to projection area 05, that is, projection area 05 and the second projection area 06 where the user is located are both determined as the first projection area; the user's direction of travel is directly pointing to projection area 07, that is, projection area 07 and the second projection area 06 where the user is located are both determined as the first projection area.

[0108] Furthermore, in one implementation, when the user moves laterally, the user's direction of movement is predicted by the location, and a video is played showing a puppy running out of the current sensing area, followed by a dynamic effect of a puppy running into the sensing area corresponding to the user's direction of movement and crouching down to wait for the user's next action.

[0109] That is, when the user moves from projection area 06 to projection area 07, the content of the first welcoming video corresponding to 06 is an animation of a puppy running from area 06 to area 07, and the content of the first welcoming video corresponding to 07 is an animation of a puppy running from area 06 into area 07.

[0110] When the user moves from projection area 06 to projection area 05, the content of the first welcoming video corresponding to 06 is an animation of a puppy running from area 06 to area 05, and the content of the first welcoming video corresponding to 05 is an animation of a puppy running from area 06 into area 05.

[0111] It should be understood that: Figure 11 As the user moves, their location information is updated in real time.

[0112] The vehicle welcome method provided in this invention determines a second projection area where the real-time location information is located within multiple projection areas. If the real-time travel direction does not point to an adjacent projection area outside the second projection area, the second projection area is designated as the first projection area. If the real-time travel direction points to an adjacent projection area outside the second projection area, the adjacent projection area and the second projection area are designated as the first projection area. This solution dynamically determines the correlation between the user's travel direction and their current projection area, intelligently distinguishing whether the user is remaining in their original area or transitioning to an adjacent area. This not only achieves adaptive matching between the projected content and the user's movement path but also ensures the smoothness of the welcome effect and the rationality of spatial logic in complex multi-area scenarios, significantly improving the accuracy of interaction and the intelligence of environmental perception.

[0113] Figure 12 A flowchart of a third embodiment of the vehicle welcoming method provided by the present invention is shown, the method being performed by the vehicle. Figure 12 As shown, step 24 may include:

[0114] Step 121: If the first projection area is the second projection area, project the first welcoming video corresponding to the second projection area;

[0115] In this step, when the user's lateral movement is not determined, the first projection area is the current second projection area, and only the first welcoming video of the second projection area (such as a static welcoming scene of a puppy crouching down and waiting) is projected.

[0116] Step 122: If the first projection area is the second projection area and the adjacent projection area, project the first welcoming video according to the real-time location information.

[0117] In this step, when it is determined that the user is moving laterally, the first projection area includes the second projection area and the adjacent projection area. At this time, the first welcoming video corresponding to the second projection area and the adjacent projection area is dynamically switched according to the user's real-time position.

[0118] Optionally, step 122 may include the following implementation:

[0119] Step 1: If the real-time location information indicates that the user is located in the second projection area, project the first welcoming video corresponding to the second projection area;

[0120] In this implementation, when the user is in the second projection area, a welcoming video of a puppy running towards the adjacent projection area can be projected from the second projection area, that is, the corresponding first welcoming video in the second projection area can be projected.

[0121] Step 2: If the real-time location information indicates that the user has entered the adjacent projection area, project the first welcoming video corresponding to the adjacent projection area.

[0122] In this design, the objects in the first welcoming video corresponding to the second projection area are displayed in a seamless manner with the objects in the first welcoming video corresponding to the adjacent projection area.

[0123] In this implementation, when a user enters an adjacent projection area, the projection stops in the area where the user was before entering the adjacent projection area, i.e., the first welcoming video corresponding to the second projection area.

[0124] Previously, in the first welcoming video corresponding to the second projection area, the puppy followed the user's direction of movement to the junction. At this point, in the projection area of ​​the junction, the puppy ran from the junction towards the welcoming video in the center of the junction projection area, that is, the first welcoming video corresponding to the junction projection area (i.e., as described above). Figure 11 (Implement as shown).

[0125] The vehicle welcome method provided in this embodiment of the invention projects a first welcome video corresponding to the second projection area if the first projection area is the second projection area; and a first welcome video based on real-time location information if the first projection area is both the second and adjacent projection areas. Based on the determination of the first projection area, this solution can execute differentiated projection strategies: when the user is in a single area, the first welcome video for that area is projected, ensuring precise matching of content and space; when the user is in a transitional area, a continuous first welcome video is projected in the relevant area based on the real-time location, achieving seamless connection and dynamic extension of visual guidance. This not only ensures a high degree of synchronization between the welcome projection and the user's actual position and movement intention, but also avoids abrupt jumps or interruptions in video content at area boundaries through intelligent content switching strategies. This creates a smooth, continuous, and guiding immersive welcome experience in complex spaces, significantly enhancing the naturalness of the interaction and the overall integrity of the technological experience.

[0126] Figure 13 A schematic diagram of an embodiment of the vehicle welcome device provided by the present invention is shown. Figure 13 As shown, the device includes:

[0127] The acquisition module 131 is used to acquire the user's real-time location information and real-time direction of travel;

[0129] The second determining module 133 is used to determine the first welcoming video corresponding to the first projection area and the real-time direction of travel in the welcoming video set. The welcoming video set includes: at least one welcoming video corresponding to different projection areas, and the movement direction of the object in each welcoming video is associated with the user's direction of travel.

[0130] Processing module 134 is used to project the first welcoming video.

[0132] The second projection area where the real-time location information is located is determined from multiple projection areas;

[0133] If the real-time direction of travel does not point to a projection area adjacent to the second projection area, the second projection area will be designated as the first projection area.

[0134] If the real-time travel direction points to a projection area adjacent to the second projection area, the adjacent projection area and the second projection area are determined as the first projection area.

[0135] In one or more embodiments, the processing module 134 projects a first welcoming video, specifically for:

[0136] If the first projection area is the second projection area, project the first welcoming video corresponding to the second projection area;
