[0045] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0046] Please refer to Figure 1 , Figure 1A structural schematic diagram of a vehicle is disclosed in the embodiments of the present application. The vehicle 100 can be, but is not limited to, a pure electric vehicle (PEV / BEV), a hybrid electric vehicle (HEV), a range extended electric vehicle (REEV), a plug-in hybrid electric vehicle (PHEV), a new energy vehicle, etc.

[0047] In the embodiments of the present application, the vehicle 100 includes a vehicle body 101, a target device 102, a camera device 103, a vehicle door 104, and a vehicle welcoming device 105. The vehicle welcoming device 105, the camera device 103, the vehicle door 104, and the target device 102 are all mounted on the vehicle body, and the vehicle welcoming device 105 respectively establishes a communication connection with the target device 102, the camera device 103, and the vehicle door 104. After receiving an unlocking signal of the vehicle 100, the vehicle welcoming device 105 generates and issues a control instruction corresponding to the target device 102, so as to perform welcoming control on the target device 102 until it receives an opening signal of the vehicle door 104, and then controls the target device 102 to reset to an initial state.

[0048] The target device 102 can include a rearview mirror and a projection device.

[0049] As a feasible implementation manner, as shown in the figure, Figure 2 The rearview mirror can include a cover 11, a side turn signal lamp 12, a lens assembly 13, a mirror shell 14, a mirror arm assembly 15, and an integrated adjuster 16.

[0050] The cover 11 is used to protect the internal components of the rearview mirror, optimize the appearance of the rearview mirror, and improve the visual consistency of the vehicle.

[0051] The side turn signal lamp 12 is used to issue light warning and prompt signals in the vehicle turning, lane changing, and welcoming interaction scenarios, to ensure driving safety while adapting to the welcoming light interaction demand.

[0052] The lens assembly 13 undertakes the functions of imaging the road conditions behind the vehicle and presenting the field of view, and provides a clear rear view angle for the driver and passengers.

[0053] The mirror shell 14, as an external protective structure of the rearview mirror, can effectively isolate external environmental interference such as dust and rain, and protect the lens assembly 13 and internal electronic control components.

[0054] The mirror arm assembly 15 is used to stably connect the rearview mirror to the vehicle body, to realize mechanical fixation of the rearview mirror to the vehicle body, and to adapt the overall installation and position adjustment of the rearview mirror.

[0055] The integrated adjuster 16 is used to control accurate adjustment of the mirror angle of the rearview mirror. The integrated adjuster 16 is internally provided with a double-path adjustment motor capable of respectively controlling horizontal and vertical rotation of the rearview mirror, and is provided with at least two functional modules for controlling the position of the rearview mirror. The functional modules can be any one or combination of an incremental encoder, an absolute encoder, a limit post, etc. Relying on a matched rotating mechanism, the integrated adjuster 16 can realize horizontal and vertical rotation adjustment of the rearview mirror, and meet the visual field adjustment needs of different drivers and passengers and the angle adjustment requirements in a welcoming scenario. For example, as shown in FIG. 7, the rearview mirror can be rotated by 140° horizontally or 40° vertically. Figure 3

[0056] As a feasible implementation manner, the projection device and the camera device can be integrated and arranged inside the mirror housing 14 of the rearview mirror or in a pre-set installation area of the mirror cover 11. This integrated arrangement scheme can fully take advantage of the installation position of the rearview mirror outside the vehicle body. On the one hand, the camera device can efficiently collect all kinds of welcoming related data such as the position of personnel around the vehicle and environmental features without obstruction in all directions, to provide reliable data support for subsequent accurate formulation of welcoming strategies. On the other hand, the projection device can flexibly project diversified welcoming patterns, dynamic light and shadow effects or vehicle prompt information towards the side of the vehicle, the ground around the vehicle body, etc., which not only enriches the presentation form of the welcoming interaction, but also effectively improves the user visual experience. Meanwhile, this arrangement manner does not need to occupy other installation space of the vehicle body, and can maximize the saving of the vehicle layout space. On the basis of improving the integration degree of the vehicle-mounted device, the rationality of the welcoming interaction effect and the vehicle structure layout is taken into account. In addition, a differentiated split arrangement scheme can also be adopted, i.e., the camera device is separately embedded in a reserved installation position of the mirror arm assembly 15 of the rearview mirror, and the projection device is fixed and assembled in a pre-set work station at the front end of the mirror housing 14 of the rearview mirror. Both the two arrangement manners can realize stable mounting of the camera device and the projection device and normal operation of the functions, and can flexibly adapt to the vehicle body structure design requirements and functional configuration needs of different vehicle models, and have strong practicality and adaptability. Moreover, the camera device and the projection device are rigidly connected with the rearview mirror body, and can follow the rearview mirror to complete horizontal and vertical angle rotation and position movement throughout the process, so as to ensure that the camera device always maintains the best environmental collection angle and the projection device always maintains the stable projection direction during the posture adjustment of the rearview mirror, and to protect the camera collection and projection display effects from being affected by the movement of the rearview mirror.

[0057] ​The projection device can be selected from a wide range, including but not limited to a high-definition lamp (HD lamp) and a digital light processing lamp (DLP lamp), and can be selected flexibly according to the configuration requirements of the vehicle model and the presentation requirements of the welcome effect, to meet the differentiated needs of different grades of vehicle models for projection resolution and light and shadow effects. The camera device has high-performance image acquisition capability, can realize 1080P resolution and 30FPS frame rate of high-definition video recording, can clearly and smoothly capture dynamic pictures and static features around the vehicle, can accurately identify the key information such as the user position and the moving track, and can provide high-quality data basis for the intelligent decision of the welcome device of the vehicle. At the same time, the high-definition recording capability can also meet the image recording requirements in the driving scene, and realize one preparation for multiple uses.

[0058] Please refer to Figure 4 , Figure 4 A structure diagram of a welcome device of a vehicle is disclosed in an embodiment of the present application. The welcome device 105 of the vehicle comprises a determination module 401 and a control module 402. The determination module 401 is configured to determine a control instruction of a target device when receiving an unlocking signal of the vehicle. The control instruction of the target device comprises a first control instruction of a rearview mirror. The first control instruction is configured to make the rearview mirror produce a nodding effect. The control module 402 is configured to control the target device based on the control instruction, so as to realize the welcome of the vehicle.

[0059] In a possible embodiment, the control instruction of the target device further comprises a second control instruction of a projection device. The second control instruction is configured to control the projection device to project a preset welcome pattern to the side of the vehicle body.

[0060] In an embodiment, the control instruction of the target device further comprises a third control instruction of the projection device. The third control instruction is configured to control the projection device to project a light carpet to an area where a user is located when the ambient brightness of the vehicle is less than or equal to a preset brightness.

[0061] In some embodiments, the third control instruction is configured to control the projection device to project the light carpet to the area where the user is located when the ambient brightness of the vehicle is less than or equal to the preset brightness.

[0062] In an exemplary embodiment, the projection device and the camera device are arranged on the rearview mirror. The welcome device of the vehicle further comprises a rotating module 403. The rotating module 403 is configured to rotate the rearview mirror after the light carpet is projected to the area where the user is located, so that the center of the light carpet is at a target position. The target position is the position of the user identified by the camera device.

[0063] In the example embodiment, the determining module is further configured to determine a moving track of the target position based on the image video stream collected by the camera device; and rotate the rearview mirror so that the center of the light carpet moves along the moving track.

[0064] In the example embodiment, the control module 402 is further configured to control the rearview mirror to return to the initial state and control the projection device to be turned off when the door is opened, wherein the initial state is a best working state set for vehicle driving.

[0065] In the example embodiment, the camera device is arranged on the rearview mirror; and the control module 402 is further configured to control the rotation of the rearview mirror so that the focal point position of the camera device is at the target focal point position when the vehicle is in the parking state and the camera mode is turned on.

[0066] In the example embodiment, the control module 402 is further configured to control the rearview mirror to return to the initial state and control the camera mode to be turned off when the vehicle is switched to the driving state, wherein the initial state is a best working state set for vehicle driving.

[0067] In the example embodiment, when the camera device captures a landscape image, the target focal point position is a focal point position input by the user; and when the camera device captures the user, the target focal point position is the position of the user.

[0068] Please refer to Figure 5 , Figure 5 A flowchart of a welcoming method of a vehicle disclosed in the example embodiment of the present application.

[0069] In some embodiments, the welcoming method of the vehicle can be implemented as the following steps: S501, in the case of receiving an unlocking signal of the vehicle, determining a control instruction of a target device.

[0070] The control instruction of the target device includes a first control instruction of the rearview mirror, and the first control instruction is used to make the rearview mirror produce a nodding effect.

[0071] The unlocking signal of the vehicle is used to represent that the vehicle has successfully received an unlocking instruction, and is a core trigger signal for permitting the vehicle to perform an unlocking operation and subsequent full-process welcoming related actions; the unlocking signal can be generated by various unlocking methods, including an intelligent key unlocking signal, a mobile phone remote control unlocking signal, a face recognition unlocking signal, a fingerprint unlocking signal, a Bluetooth unlocking signal, and a passive unlocking signal triggered by a vehicle keyless entry system.

[0072] As a feasible implementation manner, after receiving the vehicle unlocking signal, a first control instruction for controlling the rearview mirror to complete a vertical rotation nodding action is generated, thereby providing accurate control basis for the rearview mirror to perform a welcoming action.

[0073] Optionally, before performing the nodding and greeting action of the rearview mirror, the current state of the rearview mirror can be detected and judged in real time. If it is detected that the rearview mirror is in a folded or retracted state, a rearview mirror unfolding instruction is issued in priority to drive the rearview mirror to complete a full unfolding action. After the rearview mirror is stabilized at a normal unfolded position, the preset vertical rotation nodding and greeting process is continued to ensure that the greeting action of the rearview mirror can be successfully implemented according to the standard process, and the integrity and fluency of the greeting interaction effect are ensured.

[0074] S502, based on the control instruction, controlling the target device to realize vehicle greeting.

[0075] In an example embodiment, the control instruction drives the rearview mirror to rotate in the vertical direction to complete two consecutive and smooth nodding and greeting actions. The normal unfolded position of the rearview mirror is used as the action starting reference for each single nodding action. The rearview mirror is first rotated by a set angle in the vertical upward direction, and then rotated by twice the angle in the vertical downward direction, and finally accurately reset to the initial normal unfolded position. The two nodding actions are sequentially connected and smoothly executed. Through the humanized dynamic greeting effect, the interaction experience between the vehicle and the user is strengthened, and the sense of ceremony and the use of pleasure when the user unlocks the vehicle are improved.

[0076] It should be understood that the number of nods actually performed by the rearview mirror and the vertical rotation angle in the single nodding process can be flexibly adjusted and set according to the user's personalized customization needs or the functional configuration requirements of different vehicle models. The above-mentioned action process of two nods is only an example implementation manner of the present scheme and does not constitute a limitation on the present technical scheme. It can be extended to adapt to more diversified greeting action design requirements.

[0077] Upon receiving the unlocking signal of the vehicle, the first control instruction of the rearview mirror is determined and executed to drive the rearview mirror to complete the humanized nodding and greeting action. The mechanical action creates a very ceremonial greeting effect, breaks the cold interaction barrier between the vehicle and the user, and conveys the greeting in a lively and humanized manner. The experience and use of pleasure when the user unlocks the vehicle are effectively improved.

[0078] In some embodiments, in order to further enrich the presentation form of the vehicle greeting interaction, strengthen the visual impact of the greeting effect, and improve the user's sense of ceremony and personalized experience of using the vehicle, the vehicle greeting can also be realized by controlling the projection device.

[0079] As a feasible implementation manner, the control instruction of the target device further includes a second control instruction of the projection device.

[0080] The second control instruction is used to control the projection device to project a preset welcome pattern to the side of the vehicle body. The welcome greeting can be delivered through a clear and vivid light and shadow pattern, and exclusive elements can be presented in combination with vehicle positioning, brand identification or user personalized needs, so that the welcome interaction has more recognition and emotional temperature, and the distance between the vehicle and the user is further shortened.

[0081] As a feasible implementation manner, the preset welcome pattern can be a pattern pre-set at the factory; or, the preset welcome image can also be a pattern customized by the user.

[0082] In an example embodiment, a vehicle enterprise designs exclusive welcome patterns (such as brand logos, vehicle exclusive identification, general welcome slogans, etc.) according to vehicle positioning, brand style, and preloads the welcome patterns in the welcome device of the vehicle, which can be directly selected by the user.

[0083] In another example embodiment, the vehicle supports uploading a pattern designed by the user (which needs to meet the format and size specifications) through a terminal such as a car machine system or a mobile phone APP, or selecting and editing (such as adding text, adjusting color, etc.) a pattern from a pattern library provided by the welcome device of the vehicle, to realize exclusive customization of the welcome pattern.

[0084] In an example embodiment, after the welcome device receives a vehicle unlocking signal, it synchronously completes the state detection of the projection device (such as whether the device is normally on standby, whether the projection angle is reset, whether the light source is normal, etc.); if it is detected that the state of the projection device is normal, it retrieves corresponding welcome pattern data from the preset pattern library in combination with the current unlocking scene (such as unlocking by a smart key, remote unlocking by a mobile phone, etc., which can adapt to different pattern projection priorities); then, it generates a second control instruction containing pattern data, projection angle parameters, projection brightness parameters, and projection time length parameters (such as maintaining projection for 3 seconds after the door is opened); finally, it issues the second control instruction to the projection device through the vehicle-mounted communication link, and the projection device receives the instruction, adjusts its posture and working state according to the parameters, accurately projects the welcome pattern to the preset area of the side of the vehicle body, and simultaneously returns a feedback signal of successful projection start to the welcome device, to complete the execution closed loop of the second control instruction.

[0085] It should be understood that the introduction of the second control instruction and the projection device can effectively compensate for the experience limitations of a single mechanical welcome action, enrich the dimension and level of the welcome interaction by means of the visual presentation form of light and shadow projection, and greatly improve the visual appeal and aesthetics of the welcome effect; at the same time, the personification action of the rearview mirror and the light and shadow effect of the projection device are cooperated and linked to synchronize the welcome, which can build a more complete and more immersive ritual feeling of the welcome interaction process, further strengthen the intelligent interaction attribute of the vehicle, and comprehensively improve the competitiveness of the whole vehicle product and the user's experience satisfaction.

[0086] As a feasible implementation manner, the second control instruction can be used to control the projection device to project the welcome pattern to the side of the vehicle body when the ambient brightness of the vehicle is greater than the preset brightness.

[0087] The ambient brightness is used to represent the light and shade degree of the external scene where the vehicle is located, and can intuitively reflect the lighting conditions of the current period. The specific value can be acquired in real time by a light sensor, a camera device or a photosensitive module integrated in a rearview mirror carried by the vehicle, thereby providing accurate environmental determination basis for the start-stop control of the projection device.

[0088] In the example embodiment, after receiving the vehicle unlocking signal and generating the second control instruction, the ambient brightness data of the vehicle surrounding environment acquired in real time by the light sensor is synchronously called and compared with the preset brightness threshold in real time. If it is determined that the current ambient brightness is greater than the preset brightness threshold, the projection device will be immediately sent a projection instruction to control the projection device to start and project the welcome pattern to the specified area of the side of the vehicle body, and the projection state is maintained until the welcome device receives the vehicle door opening signal. If it is determined that the current ambient brightness does not reach the preset brightness threshold, the projection action of the projection device is not triggered, and only the mechanical welcome action of the rearview mirror is relied on to complete the interaction, so as to ensure that the projection welcome effect is adapted to the current lighting conditions.

[0089] It should be understood that when the ambient brightness is sufficient, the projection pattern can be clearly and completely presented on the side of the vehicle body, and the recognition degree of the light and shadow effect is higher, which can effectively transmit the welcome visual information and bring a clear and intuitive visual experience to the user. If the projection is performed in a dark environment, the pattern may be blurred and the visibility is poor due to the interference of ambient light, which cannot achieve the expected welcome effect, but causes ineffective operation of the device.

[0090] In some embodiments, in order to further improve the user's driving experience and create a more exclusive and immersive welcome interaction scene, a third control instruction for the projection device can be added to the control instruction system of the target device. The third control instruction drives the projection device to realize the light carpet projection function, cooperates with the personification action of the rearview mirror and the projection of the conventional welcome pattern in multiple dimensions, builds a more complete and more ritual welcome process, further strengthens the intelligent property of the vehicle, and improves the product competitiveness and user experience satisfaction of the whole vehicle.

[0091] As a feasible implementation manner, the third control instruction is used to control the projection device to project the light carpet to the area where the user is located.

[0092] The light blanket refers to a planar light area with a specific range and brightness projected by a projection device, and the light area presents uniform and soft, which can be a pure color light area (such as warm white color, brand exclusive color), or a gradient light area with slight dynamic effect. The light blanket can not only clearly guide the user to the boarding and alighting area through the eye-catching visual effect, but also create a dignified and warm welcome atmosphere. In addition, the light blanket can also assist in illuminating the area under the user's feet in a relatively dark scene, thereby improving the safety and convenience of boarding and alighting.

[0093] The user's area can be determined based on the following methods: relying on a camera device integrated in the rearview mirror or other positions of the vehicle body, real-time collection of 360° environment images around the vehicle (focusing on covering the user's common approaching areas such as the side and rear of the vehicle); the camera device transmits the collected image data to the welcome device through the vehicle communication link in real time, and the welcome device has an image recognition algorithm built-in, which accurately detects and recognizes human features (such as outline, limb shape, etc.) in the image; at the same time, combined with the mapping relationship between the image coordinate system and the physical coordinate system of the vehicle, the specific position coordinates of the user relative to the vehicle are converted, and then the core area where the user is located (such as the left rear side of the vehicle, the right front side of the vehicle, etc.) is determined; in addition, in order to improve the recognition accuracy and stability, the signal positioning data of the intelligent key can also be used for auxiliary verification to ensure the accuracy of the determination of the user's area.

[0094] In an exemplary embodiment, after the welcome device receives the vehicle unlocking signal, the camera device is triggered to start and collect the environment images around the vehicle, and the environment brightness data collected by the light sensor is also retrieved; the environment images are processed by the image recognition algorithm to accurately identify and determine the position coordinates of the user's area, and if the environment brightness is lower than the preset threshold (i.e. a relatively dark scene), it is determined that the light blanket projection function needs to be started, and a third control instruction is generated immediately, which includes the projection angle parameters corresponding to the user area coordinates, the light blanket light area parameters (such as color, brightness, range), and the projection time length parameters; It should be understood that the execution of the first control instruction is for a short-time operation after the vehicle is unlocked, while the third control instruction is a continuous welcome execution instruction. The execution logic of the first control instruction is to complete the nodding action of the rearview mirror first, and then start the light blanket projection, which are time-sequential and do not conflict with each other. The projection device is integrated in the rearview mirror, and after the first control instruction drives the rearview mirror to complete the nodding welcome action in the vertical direction and resets to the normal unfolded position, the third control instruction is executed to control the projection device to accurately project the light blanket to the user's area; this sequential execution mode can ensure that the rearview mirror completes the personification welcome action, and at the same time, the projection device relies on the reset position of the rearview mirror to realize stable and accurate light projection, which not only guarantees the independent presentation of the two types of welcome effects, but also realizes the orderly connection of the action and the light, making the overall welcome process more hierarchical and smooth.

[0095] As a feasible implementation manner, the third control instruction is used to control the projection device to project a light carpet to the area where the user is located in a case where the ambient brightness of the vehicle is less than or equal to a preset brightness.

[0096] In the example embodiment, in a case where the ambient brightness of the vehicle is less than or equal to a preset brightness, the third control instruction is immediately issued to start the projection device to light up the light carpet in the area near the vehicle; at the same time, the camera device is triggered to start the personnel search mode to carry out real-time image acquisition and human feature recognition on the surrounding environment of the vehicle to complete accurate positioning of the user's location; after the user's location is determined, the corresponding outside rearview mirror is further driven to rotate in angle to drive the projection device integrated on the rearview mirror to synchronously adjust the projection angle, so that the center of the light carpet is accurately focused on the area under the user's feet; the camera device will continue to track and identify the user's location, and dynamically adjust the projection angle of the projection device according to a preset frequency to realize real-time adaptation of the light carpet position to the user's movement, and always keep accurate coverage of the light carpet to the user's travel route.

[0097] It should be understood that in a case where the ambient brightness of the vehicle is less than or equal to a preset brightness, the light is dim, and the user's visual condition is poor when approaching the vehicle, and the control of the projection device to project the light carpet can directly provide illumination for the area under the user's feet, effectively avoiding safety hazards such as road obstacles, accumulated water, steps, etc., and significantly improving the safety and convenience of the user approaching the vehicle at night or in a dark environment. In addition, the light and shadow contrast effect is more distinct in a dark environment, the visual guidance of the light carpet is stronger, and the vehicle boarding and alighting area can be accurately marked to help the user quickly locate the door position, while creating a warm and ritualistic welcoming atmosphere; thirdly, in combination with the angle adjustment of the outside rearview mirror and the dynamic following of the light carpet, exclusive visual service can be realized for the user in a dark light scene, which makes up for the deficiency of weak visibility and poor interactivity of the conventional welcoming effect in a low brightness environment, adapts to the welcoming needs in different light scenes, and comprehensively improves the user's vehicle experience.

[0098] In some embodiments, in order to make the light carpet projection effect more in line with the actual needs of the user, accurate visual guidance and illumination coverage for the user can be realized by accurately determining the projection center of the light carpet according to the identified user location.

[0099] As a feasible implementation manner, after the light carpet is projected to the area where the user is located, the rearview mirror is rotated to make the center of the light carpet at the target position.

[0100] The target position is the user's location identified by the camera device.

[0101] The target position determination manner comprises: a camera device integrated in the rearview mirror collects vehicle surrounding environment images in real time after the welcome process is started, and through a built-in human feature recognition algorithm, human body contours, limb shapes and other features in the images are accurately detected and extracted; the user position recognized in the images is converted into accurate spatial coordinates in the vehicle coordinate system in combination with the mapping and conversion relationship between the image coordinate system and the vehicle physical coordinate system, so that the specific orientation of the user relative to the vehicle is determined, i.e., the target position is obtained; and the signal strength positioning data of the intelligent key can be combined for auxiliary verification to further improve the accuracy and real-time performance of the target position determination.

[0102] In the example embodiment, when the vehicle unlocking signal is received and it is determined that the ambient brightness is less than or equal to the preset brightness, a third control instruction is issued to start the projection device to project an initial light carpet to the area near the vehicle; at the same time, the camera device on the rearview mirror is turned on for personnel recognition and positioning, and accurate calibration of the target position of the user is completed; the welcome device generates a rearview mirror angle adjustment sub-instruction based on the coordinate data of the target position, drives the outside rearview mirror in the corresponding direction to rotate accurately in the horizontal and vertical directions, and drives the projection device integrated in the rearview mirror to adjust the projection angle synchronously; after the rearview mirror is rotated to the preset angle, the projection direction of the projection device is adapted accordingly, and the center of the light carpet is accurately focused on the target position of the user's feet identified; the camera device continuously tracks the user's moving track, updates the target position coordinates in real time, and the welcome device issues a rearview mirror fine adjustment instruction at a preset frequency to realize that the center of the light carpet always follows the user's position to adapt dynamically.

[0103] It should be understood that after the light carpet is projected to the area where the user is located, the rearview mirror is further rotated and adjusted in angle, driving the projection device to adjust the projection direction synchronously, so that the center of the light carpet is accurately aligned with the position where the user is located; this can make the lighting function and visual guiding effect of the light carpet accurately act on the user's body, maximize the coverage of the user's travel route and the area under the feet, effectively eliminate the visual blind area around the user in the dark environment, and effectively ensure the safety of the user's walking when approaching the vehicle, while improving the exclusivity and adaptability of the light carpet welcome.

[0104] Optionally, the third control instruction can be executed synchronously with the second control instruction, or can be executed in combination with the brightness differentiation of the environment around the vehicle. Embodiments of the present application do not limit the execution combination of the two. Specifically, the execution strategy of the instruction can be flexibly adapted according to the comparison result of the real-time collected environmental brightness and the preset brightness: when the environmental brightness is greater than the preset brightness, the second control instruction is preferentially executed to control the projection device to project the welcome pattern to the side of the vehicle body, so as to ensure that the pattern is clearly visible with sufficient light and to strengthen the visual welcome effect; when the environmental brightness is less than or equal to the preset brightness, the third control instruction is preferentially executed to control the projection device to project the light carpet to the area where the user is located, so as to meet the lighting and precise guidance requirements in a dark light scene; or the two control instructions can be triggered synchronously in any brightness scene to realize the superimposed presentation of the welcome pattern and the light carpet projection, further enrich the visual level of the welcome interaction, and adapt to the diversified needs of different users for the welcome effect.

[0105] In some embodiments, the projection device integrated on the rearview mirror can be rotated to synchronously adjust the projection angle, so that the center of the light carpet can dynamically move in real time to follow the moving track of the user, and continuously provide sufficient light and precise guidance for the user's travel path.

[0106] As a feasible implementation manner, as shown in Figure 6 The welcome method of the vehicle can further include the following steps: S601, determining the moving track of the target position based on the image video stream collected by the camera device.

[0107] The image video stream collected by the camera device is used to represent the dynamic image data of the environment around the vehicle captured by the camera device at a preset frame rate, which can record the changes of the pictures and the movement process of the objects around the vehicle, and provide continuous and real-time visual basis for user position recognition and track tracking.

[0108] The moving track is used to represent the continuous displacement path of the position of the user as time elapses during the approach to the vehicle, and reflects the travel direction and movement trend of the user.

[0109] In an exemplary embodiment, the image video stream of the vehicle around collected by the camera device integrated in the rearview mirror is acquired, a human target tracking algorithm is called to analyze each frame of the video stream frame by frame, the human feature target of the user is accurately locked, and the position coordinates of the user in each frame of image are extracted; based on the position coordinate changes of the continuous frames, the displacement data in the time dimension are combined to generate the real-time movement path of the user around the vehicle, that is, the moving track of the target position of the user is obtained, and the track is updated in real time to ensure the timeliness and accuracy of the track data.

[0110] S602, rotating the rearview mirror to move the center of the light carpet along the moving track.

[0111] In the example embodiment, after obtaining the real-time changing trajectory of the target position of the user, the horizontal and vertical rotation angle parameters required for adjustment of the rearview mirror are calculated in real time according to the displacement direction and distance of the trajectory; then, the dynamic adjustment instruction of the rearview mirror is generated and sent to the integrated adjuster of the rearview mirror, to drive the horizontal and vertical adjustment motors built in the adjuster to rotate the rearview mirror according to the calculated angle parameters; the rearview mirror drives the projection device to complete the angle adjustment synchronously, and the projection direction of the projection device is adapted accordingly, so that the center of the light carpet can accurately follow the changing trajectory of the user and always point to the current position of the user.

[0112] In some embodiments, in order to reasonably control the start and stop rhythm of the welcoming process, avoid invalid energy consumption, and ensure the normal use and connection of the vehicle, the vehicle welcoming is stopped when the vehicle door is detected to be opened.

[0113] As a feasible implementation manner, in the case that the vehicle door is opened, the rearview mirror is controlled to return to the initial state, and the projection device is controlled to be turned off.

[0114] The initial state is used to represent the optimal working state set for vehicle driving.

[0115] In the example embodiment, in the process of executing the control instruction, the state of the vehicle door is obtained in real time, and when any vehicle door is detected to be opened, the rearview mirror reset instruction is immediately generated and sent to the integrated adjuster of the rearview mirror, to drive the integrated adjuster to accurately control the rearview mirror to complete angle correction and quickly reset from the welcoming action posture to the preset initial driving state; at the same time, the projection device delay shutdown instruction is generated, to control the projection light carpet to keep the projection state and start timing, and after the preset delay time is reached, the shutdown instruction is sent to control the projection device to turn off the light source and terminate the projection of the light carpet, to complete the welcoming ending of the projection device; after the rearview mirror is reset and the projection device is turned off, the current vehicle welcoming process is formally ended.

[0116] It should be understood that controlling the rearview mirror to return to the optimal working state can ensure that the user does not need to manually adjust after getting on the vehicle, directly obtains the optimal driving view, and greatly improves the convenience of vehicle operation, to adapt to the working condition requirement that the vehicle is about to enter the driving state. Controlling the projection device to be turned off can avoid the visual interference caused by light projection during vehicle driving, and protect the light source components of the projection device and prolong the service life of the device.

[0117] In some embodiments, the camera device on the rearview mirror can also be used for shooting.

[0118] As a feasible implementation manner, in the case that the vehicle is in the parking state and the camera mode is turned on, the rotation of the rearview mirror is controlled, so that the focal point position of the camera device is at the target focal point position.

[0119] The target focus position is used to represent a core area or subject position that needs to be aligned by the camera device during shooting, and is a core reference position for the camera device to complete focusing and framing. The target focus position can be flexibly switched and adjusted according to the shooting requirements of the user.

[0120] In an example embodiment, when the vehicle is in the parking mode, the user enters the camera shooting mode through the vehicle interface or the mobile phone APP interface, and the corresponding operation interface synchronously opens the shooting framing frame. The camera device on the rearview mirror is triggered to start and enter the working state. The rearview mirror is driven to complete the angle adjustment in the horizontal and vertical directions according to the shooting requirements selected by the user, and the camera device is synchronously adjusted to the shooting angle until the focus point of the camera device accurately falls on the target focus position, thereby ensuring the accuracy of the shooting framing.

[0121] It should be understood that, by relying on the rotation adjustment function of the rearview mirror and the camera device, the limitation of fixed angle shooting can be broken, the multi-dimensional adjustment of the shooting angle of the camera device can be realized through the flexible rotation of the rearview mirror, different shooting scenes and focusing requirements can be adapted, multi-directional and multi-angle shooting can be completed without moving the vehicle, and the convenience of shooting operation and the flexibility of shooting effect are greatly improved.

[0122] As a feasible implementation manner, when the camera mode is opened, the user can select to shoot a landscape image or a person according to actual requirements, and the target focus position of the camera device is differentiated according to the selection of the user, thereby meeting the use requirements of different shooting scenes.

[0123] In an example embodiment, when the camera device shoots a landscape image, the target focus position is the focus position input by the user.

[0124] For example, the camera mode is by default in the normal shooting mode, at this time, the rearview mirror drives the camera device to initially face the side of the vehicle, the user can manually operate the zooming, angle moving and other adjustment actions in the framing frame interface of the vehicle or the mobile phone APP to autonomously select the target focus position for landscape shooting, the rearview mirror is rotated according to the manual operation of the user to make the camera device always align with the focus position set by the user, and custom landscape shooting is realized.

[0125] In another example embodiment, when the camera device shoots a user, the target focus position is the position of the user.

[0126] For example, the user can switch the shooting mode to the tracking shooting mode on the operation interface. The rearview mirror will drive the camera device to rotate horizontally and slowly, and automatically search for people in the surrounding area of the vehicle. When the camera device recognizes and locks the person, it will adjust the rotation angle of the rearview mirror in real time, and always keep the photographed person in the center of the viewfinder, and automatically start the recording function. If no person is recognized in the initial search, the camera device will reset to the initial viewing angle of the vehicle, and trigger a new round of person search at a preset time interval until the person is successfully locked and the tracking shooting is completed.

[0127] In some embodiments, in order to ensure the driving safety and equipment use specification during the driving of the vehicle, it is necessary to reset and control the rearview mirror and the camera device when the vehicle exits the shooting scene and enters the driving state.

[0128] As a feasible implementation, when the vehicle switches to the driving state, the rearview mirror is controlled to return to the initial state, and the camera mode is turned off.

[0129] The initial state is used to represent the best working state set for vehicle driving. The angle and posture of the rearview mirror in the initial state are adjusted to the standard position that meets the driving field of view requirements, which can directly meet the rear and side field of view observation needs during vehicle driving.

[0130] In the example embodiment, during the vehicle is in the parking shooting mode, the vehicle gear state and the camera mode operation instruction are monitored in real time. When it is detected that the user actively turns off the shooting mode on the vehicle interface or the mobile phone APP interface, or the vehicle gear is switched to the driving gear, it is immediately determined that the vehicle will enter the driving state, and the rearview mirror reset instruction and the camera mode shutdown instruction are generated. On the one hand, the rearview mirror is driven to complete the angle correction, and quickly resets from the adjusted posture suitable for shooting to the preset initial state of driving, to restore the standard driving field of view. On the other hand, the camera mode is turned off, the shooting and recording work of the camera device on the rearview mirror is terminated, and it automatically returns to the driving recording mode, only retaining the conventional image recording function in the driving scene.

[0131] It should be understood that, in the case where the vehicle switches to the driving state, the rearview mirror is controlled to return to the initial state, which can ensure that the driver has a clear and compliant rear and side field of view during vehicle driving, and completely avoids the risk of blind area caused by the angle deviation of the rearview mirror in the shooting mode. In addition, turning off the camera mode can terminate the shooting related device operation, avoid the camera function occupying the computing power of the vehicle-mounted system, and distract the driver's attention, and prevent unnecessary shooting and recording during driving from wasting storage resources.

[0132] In some embodiments, as shown in Figure 7 The welcome method of the vehicle can be implemented as follows: S701, determine whether the rearview mirror is in a folded state.

[0133] S702, receive an unlock signal of the vehicle.

[0142] S711, in the case that the vehicle door is opened, control the rearview mirror to return to the initial state, and control the projection device to turn off.

[0143] The initial state is used to represent the optimal working state set for vehicle driving.

[0144] In some embodiments, as shown in Figure 8 The welcome method of the vehicle can further include the following steps: S801, in the case that the vehicle is in a parking mode, open a shooting mode.

[0145] S802, determine the shooting mode selected by the user; if the landscape shooting mode is selected, jump to step S803; if the user shooting mode is selected, jump to step S806.

[0146] S803, the user manually inputs a target focal point position.

[0147] S804, control the rearview mirror to rotate so that the focal point position of the camera device is at the target focal point position.
