Abstract
Description
Technical Field
[0001] This application relates to the field of vehicles, and more specifically, to an interference detection method, apparatus, and vehicle. Background Technology
[0002] More and more vehicles are equipped with in-cabin entertainment systems, such as rear-seat displays for rear passengers. These displays can be screens mounted on the back of the front seats, projection screens on the ceiling, or ceiling-mounted displays. When the rear-seat display is a projection screen or a ceiling-mounted display, rear passengers need to lower it to watch movies. If there are obstacles in the path of lowering the display, it will obstruct the lowering process and may damage it. Furthermore, if the rear passengers have successfully lowered the display, and then the front passengers or driver adjust the front seats backward, the front seats may collide with the rear-seat display, causing damage. Therefore, how to avoid damage to rear-seat displays has become a pressing technical problem to be solved. Summary of the Invention
[0003] This application provides an interference detection method, device, and vehicle, which effectively avoids the risk of the front seat colliding with the rear display device when it is in the lowered state, and also avoids the risk of damage to the rear display device caused by the front seat being in the lowering area of the rear display device.
[0004] In a first aspect, an interference detection method is provided, the method comprising: in response to acquiring first information, acquiring first data collected by a first sensor, wherein the first sensor includes a distance sensor and / or an image sensor, and the first information is used to indicate adjustment of the front seat and / or lowering of the rear display device; determining a first positional relationship and / or a second positional relationship based on the first data, wherein the first positional relationship is the positional relationship between a first obstacle in the lowering area of the rear display device and the rear display device, and the second positional relationship is the positional relationship between a second obstacle in the active area of the front seat and the front seat; and adjusting the state of the front seat or the rear display device based on the first positional relationship and / or the second positional relationship.
[0005] For example, the first obstacle may be a front seat, a rear passenger, an item hanging from the back of the front seat, etc. The second obstacle may be a rear display device.
[0006] Through the above technical solution, when adjusting the front seats and / or lowering the rear display device, data collected by the first sensor can be obtained. Thus, distance data and / or image data can directly determine whether there is an interference problem. The detection accuracy is high, effectively avoiding the risk of the front seats colliding with the rear display device when it is lowered, and avoiding the risk of damage to the rear display device caused by the front seats being in the lowering area of the rear display device.
[0007] In conjunction with the first aspect, in some implementations of the first aspect, the first sensor includes the distance sensor, which is arranged in any one or more of the following locations: the vehicle top area above the front seat; the center pillar of the vehicle; the side of the front seat near the rear seat; and the lower edge area of the rear display device.
[0008] In conjunction with the first aspect, in certain implementations of the first aspect, when the first information is used to instruct the lowering of the rear display device, determining the first positional relationship and / or the second positional relationship based on the first data includes: determining the positional relationship between a first part of the rear display device and the first obstacle based on the first distance data collected by the distance sensor, wherein the first part of the rear display device includes the lower edge of the rear display device.
[0009] For example, if the distance sensor is installed in the vehicle roof area above the front seats, and the detected distance is not the distance between the distance sensor and the floor, it can be determined that there is a first obstacle in the area where the rear display device is placed.
[0010] For example, if the distance sensor is installed on the center pillar of the vehicle, and the detected distance is not the distance between the distance sensor and the center pillar on the other side, it can be determined that there is a first obstacle in the lowering area of the rear display device.
[0011] For example, if the distance sensor is installed on the side of the front seat near the rear seat, and the detected distance is less than a preset threshold, it can be determined that there is a first obstacle in the lowering area of the rear display device.
[0012] For example, if the distance sensor is installed in the lower edge area of the rear display device, and the detected distance is not the distance between the distance sensor and the floor, it can be determined that there is a first obstacle in the lower area of the rear display device.
[0013] The above technical solution allows for the determination of whether a first obstacle exists in the placement area of the rear-seat display device when it is lowered, based on the first distance data. Because the distance sensor is easy to install, low in cost, and highly accurate, by rationally configuring the measurement position, it is possible to accurately determine whether interference exists, thus avoiding the risk of damage to the rear-seat display device caused by the front seats being in the placement area.
[0014] In conjunction with the first aspect, in certain implementations of the first aspect, when the first information is used to instruct adjustment of the front seat and the rear display device is in a lowered state, determining the first positional relationship and / or the second positional relationship based on the first data includes: Based on the second distance data collected by the distance sensor, the positional relationship between the first part of the front seat and the second obstacle is determined. The first part of the front seat includes any one or more of the following: the headrest of the front seat, the backrest of the front seat, the table on the back of the front seat, and items suspended on the back of the front seat.
[0015] For example, if the distance sensor is installed in the vehicle roof area above the front seat, and the detected distance is not the distance between the distance sensor and the floor, it can be determined that the distance between the front seat and the rear display device is too close, and the rear display device will obstruct the front seat, that is, the rear display device is a second obstacle to the front seat.
[0016] For example, if the distance sensor is installed on the center pillar of the vehicle, and the detected distance is not the distance between the distance sensor and the center pillar on the other side, it can be determined that the distance between the front seat and the rear display device is too close, and the rear display device will obstruct the front seat, that is, the rear display device is a second obstacle to the front seat.
[0017] For example, if the distance sensor is installed on the side of the front seat close to the rear seat, and the detected distance is less than a preset threshold, it can be determined that the distance between the front seat and the rear display device is too close, and the rear display device will obstruct the front seat, that is, the rear display device is a second obstacle to the front seat.
[0018] The above technical solution allows for the determination of whether the rear-seat display will obstruct the front seats when the rear-seat display is lowered, based on second distance data. Because the distance sensor is easy to install, low-cost, and highly accurate, by properly configuring the measurement position, it is possible to accurately determine whether interference exists, thus avoiding the risk of the front seats colliding with the rear-seat display when it is lowered.
[0019] In conjunction with the first aspect, in some implementations of the first aspect, the distance sensor is an infrared distance sensor, which includes a first infrared emitting device, a first infrared receiving device, and a second infrared receiving device. The first infrared receiving device is used to receive a first reflected light and ambient light, and the second infrared receiving device is used to receive the ambient light. The first reflected light is the reflected light corresponding to the first emitted light emitted by the first infrared emitting device.
[0020] The above technical solution can effectively eliminate the interference of ambient light, suppress ambient light interference, and improve the accuracy of measurement.
[0021] In conjunction with the first aspect, in some implementations of the first aspect, the first sensor includes the image sensor, which is arranged in any one or more of the following locations: the vehicle roof area above the front seat; the vehicle center pillar.
[0022] In conjunction with the first aspect, in certain implementations of the first aspect, when the first information is used to instruct the placement of the rear-seat display device, determining the first positional relationship and / or the second positional relationship based on the first data includes: determining second information based on the first image acquired by the image sensor, the second information including one or more of the following: the angle information of the backrest of the front seat, the position information of the front seat, the area ratio of the front seat in the first image, the opening and closing information of the front seat's table, the position information of the rear-seat user, the information of items suspended on the back of the front seat, and the displacement information of the front seat; determining the positional relationship between the first part of the rear-seat display device and the first obstacle based on the second information, wherein the first part of the rear-seat display device includes the lower edge of the rear-seat display device.
[0023] The above technical solution allows for the use of image sensors to acquire images and determine the presence of interference. Based on image recognition technology, various information about the rear display device and front seats within the image can be accurately determined, thus precisely identifying any interference issues and avoiding the risk of damage to the rear display device caused by placing the front seat in the area where the rear display device would be lowered.
[0024] In conjunction with the first aspect, in certain implementations of the first aspect, when the first information is used to instruct the adjustment of the front seat and the rear display device is in a lowered state, determining the first positional relationship and / or the second positional relationship based on the first data includes: determining third information based on the second image acquired by the image sensor, the third information including one or more of the following: the angle information of the backrest of the front seat, the position information of the front seat, the area ratio of the front seat in the second image, the opening and closing information of the table of the front seat, the information of the items suspended on the back of the front seat, and the displacement information of the front seat; determining the positional relationship between the first part of the front seat and the second obstacle based on the third information, the first part of the front seat including any one or more of the following: the headrest of the front seat, the backrest of the front seat, and the table.
[0025] The above technical solution allows for the use of image sensors to acquire images and determine the presence of interference. Based on image recognition technology, various information about the rear-seat display and front seats within the image can be accurately determined, thus precisely identifying any interference and avoiding the risk of the front seats colliding with the rear-seat display when it is lowered.

[0056] The technical solutions in this application will now be described with reference to the accompanying drawings.
[0057] Figure 1 This is a functional block diagram of a vehicle provided in an embodiment of this application. For example... Figure 1 As shown, the vehicle 100 may include a perception system 120, an interaction system 130, a display device 140, and a computing platform 150. The perception system 120 may include several sensors for sensing information about the surrounding environment of the vehicle 100. For example, the perception system 120 may include a positioning system, which may be a Global Positioning System (GPS), a BeiDou system, or another positioning system. As another example, the perception system 120 may also include one or more of the following: an inertial measurement unit (IMU), lidar, millimeter-wave radar, ultrasonic radar, and a camera device.
[0058] The camera device may include one or more cameras installed inside the vehicle cabin to capture images inside or outside the cabin. Examples include cameras from a driver monitor system (DMS), a cabin monitor system (CMS), and a dashcam. By capturing images inside the cabin, the system can determine if there are obstacles in the path of the rear-seat display device and whether there is a risk of interference between the rear-seat display device and the front seats. The cameras used to capture images inside and outside the cabin can be the same camera or different cameras. Furthermore, the perception system 120 may also include one or more distance sensors installed inside the cabin to detect obstacles in the path of the rear-seat display device and whether there is a risk of interference between the rear-seat display device and the front seats.
[0059] The interactive system 130 includes a device for receiving user instructions and a device for providing prompts to the user. The device for receiving user instructions may include at least one of the following: a sound receiving device for receiving user voice instructions, such as a microphone, transceiver, etc.; or a device for receiving instructions input by the user through a screen, such as a human-machine interface (HMI); or a camera device for receiving instructions such as user body posture, such as an in-cabin camera. The prompting device may include, but is not limited to, a sound-emitting device and a display device. More specifically, the sound-emitting device may include a speaker, audio narration device, etc., for playing audio.
[0060] The in-cabin display devices 140 are mainly divided into two categories: the first is the in-vehicle display screen; the second is the projection display screen, such as a HUD. An in-vehicle display screen is a physical display screen and an important component of the in-vehicle infotainment system. Multiple displays can be installed in the cabin, such as a digital instrument cluster display, a central control screen, a display screen in front of the front passenger (also known as the front-seat passenger), a display screen in front of the left rear passenger, a display screen in front of the right rear passenger, and even the car windows can be used as displays. A head-up display, also known as a head-up display system, is mainly used to display driving information such as speed and navigation on a display device in front of the driver (such as the windshield). This reduces the driver's eye-shifting time, avoids pupil changes caused by eye-shifting, and improves driving safety and comfort. HUDs include, for example, combiner-HUD (C-HUD) systems, windshield-HUD (W-HUD) systems, and augmented reality HUD (AR-HUD) systems.
[0061] Some or all of the functions of vehicle 100 can be controlled by computing platform 150. Computing platform 150 may include processors 151 to 15n. A processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a central processing unit (CPU), microprocessor, graphics processing unit (GPU) (which can be understood as a type of microprocessor), or digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. These logical relationships are fixed or reconfigurable. For example, the processor may be a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as a field-programmable gate array (FPGA). In reconfigurable hardware circuits, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the relevant functions. Furthermore, the processor can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), tensor processing unit (TPU), deep learning processing unit (DPU), etc. In addition, the computing platform 150 may also include a memory for storing instructions. Some or all of the processors 151 to 15n can call the instructions in the memory to implement the corresponding functions.
[0062] Figure 2This is a schematic diagram of a vehicle cockpit scenario provided in an embodiment of this application. The smart cockpit includes one or more in-vehicle displays (or in-vehicle screens), including but not limited to display screen 201 (or central control screen), display screen 202 (or passenger entertainment screen), display screen 203 (or driver's headrest rear screen), display screen 204 (or passenger headrest rear screen), display screen 205 (or second-row entertainment screen) mounted on the cockpit ceiling, and an instrument panel. Further, displays 201 to 205 can display a graphical user interface (GUI), which may include icons for one or more applications, and / or one or more cards. For example, Figure 1 The display device 140 shown may include one or more of the displays 201 to 205. Displays 203, 204, and 205 may also be referred to as rear-row display devices. In addition, the display 205 may include a retracted state and a lowered state, which can be lowered by the user when they have needs such as watching movies.
[0063] In some possible implementations, the display screen 205 can also be a projection screen associated with a projector, which can be associated with a desktop launcher to manage applications projected onto the projection screen.
[0064] The vehicles involved in this application can include road vehicles, water vehicles, air vehicles, industrial equipment, agricultural equipment, or entertainment equipment. For example, vehicles can include driverless vehicles. The term "vehicle" is used in a broad sense and can refer to vehicles (such as commercial vehicles, passenger cars, motorcycles, flying cars, trains, etc.), industrial vehicles (such as forklifts, trailers, tractors, etc.), engineering vehicles (such as excavators, bulldozers, cranes, etc.), agricultural equipment (such as lawnmowers, harvesters, etc.), amusement equipment, toy vehicles, etc. The embodiments of this application do not specifically limit the type of vehicle.
[0065] Understandably, to avoid damaging the display screen 205, there should be no obstructions along the lowering path of the display screen 205 during its lowering process, and a certain gap should be maintained between the display screen 205 and the front seats when it is in the lowered state. Therefore, how to avoid damaging the rear-seat display device has become a pressing technical problem to be solved.
[0066] Figure 3 A schematic block diagram of the interference detection system provided in an embodiment of this application is shown. Specifically, Figure 3 The interference detection system 300 shown includes an interaction module 310, a sensing module 320, and a state adjustment module 330. The interaction module 310 can be configured to... Figure 1The interactive system 130 shown is implemented by one or more devices; the function of the sensing module 320 can be achieved by... Figure 1 The function of the sensing system 120 shown is implemented by one or more devices; the function of the state adjustment module 330 can be implemented by... Figure 1 The computer platform 150 shown is implemented using one or more processors. The functions of each module are described in (I) to (III) below: (a) An interaction module 310 is used to acquire first information and send the first information to a sensing module 320. The first information is used to instruct the adjustment of the front seats and / or the lowering of the rear display device.
[0067] In some implementations, adjusting the front seat can be done by adjusting the front seat backwards, or by moving the front seat backwards and / or adjusting the seat back of the front seat backwards.
[0068] In some implementations, adjusting the front seat can be done by moving the front seat forward, which can be done by moving the front seat forward and / or adjusting the seat back of the front seat forward.
[0069] In some implementations, when the rear display device is a projection screen, lowering the rear display device can be done by lowering the projection screen.
[0070] In some implementations, when the rear-row display device is a ceiling-mounted display screen installed on the top of the cabin, lowering the rear-row display device can be achieved by folding down the ceiling-mounted display screen.
[0071] (ii) The sensing module 320 is used to receive the first information, acquire the first data detected by the first sensor, and send the first data to the state adjustment module 330.
[0072] In some implementations, the first sensor includes a distance sensor arranged inside the cockpit, such as an infrared distance sensor or an ultrasonic distance sensor. This application does not specifically limit the type of distance sensor.
[0073] In some implementations, the first sensor includes an image sensor located inside the cockpit.
[0074] In some implementations, the first sensor includes an image sensor and a distance sensor located inside the cockpit.
[0075] (iii) A status adjustment module 330 is used to determine whether there are obstacles in the lowering area of the rear display device based on the first data, and / or to determine whether there are obstacles in the moving area of the front seat based on the first data. For ease of distinction and description, in this embodiment, obstacles in the lowering area of the rear display device can be referred to as first obstacles, and obstacles in the moving area of the front seat can be referred to as second obstacles.
[0076] In some implementations, if there is a first obstacle in the lowering area of the rear display device, the state adjustment module 330 can determine the positional relationship between the first obstacle and the rear display device based on the first data.
[0077] In some implementations, if a second obstacle exists in the active area of the front display device, the state adjustment module 330 can determine the positional relationship between the second obstacle and the front seat based on the first data. For ease of distinction and description, in this embodiment, the positional relationship between the first obstacle and the rear display device can be referred to as the first positional relationship, and the positional relationship between the second obstacle and the front seat can be referred to as the second positional relationship.
[0078] Furthermore, after determining the first positional relationship and / or the second positional relationship, the state adjustment module 330 can adjust the state of the front seats and / or the rear display devices.
[0079] It should be understood that the above module is only an example, and in actual applications, the above module may be added or deleted according to actual needs.
[0080] The above describes the architecture of the interference detection system provided in the embodiments of this application. The following will be based on... Figure 3 The interference detection system shown implements the flow of the interference detection method provided in the embodiments of this application.
[0081] Figure 4 This paper presents a schematic flowchart of an interference detection method provided in an embodiment of this application. The method can be implemented by... Figure 1 The vehicle 100 shown can be used, or it can be executed by Figure 3 The system execution shown, specifically, the method 400 may include some or all of the following steps: S401, in response to obtaining the first information, first data collected by the first sensor is obtained, wherein the first sensor includes a distance sensor and / or an image sensor, and the first information is used to indicate the adjustment of the front seat and / or the lowering of the rear display device.
[0082] In some implementations, the first information can be obtained based on the user's actions, such as adjusting the front seat or lowering the rear display device.
[0083] In one example, the user's operation of adjusting the front seat could be by operating an adjustment device located on the front seat for adjusting the front seat.
[0084] In another example, the user can adjust the front seat using a voice command. For instance, the voice command could be "move the front seat back." Or, "adjust the backrest of the front seat."
[0085] In another example, the vehicle is equipped with multiple seating modes, and the user's operation of adjusting the front seat can be an operation of selecting a seating mode. For example, the vehicle can display controls corresponding to different seating modes on the central control screen. In response to the user's selection of a control, the seat mode corresponding to the selected control can be determined, and thus, initial information can be obtained.
[0086] In another example, the vehicle is equipped with a device for lowering the rear-seat display, and the user's operation of lowering the rear-seat display can be the user operating the device for lowering the rear-seat display.
[0087] In another example, lowering the rear display device could be done via a voice command from the user. For instance, the user's voice command could be "Open the projection screen." Yet another example is "Lower the ceiling-mounted screen."
[0088] In some implementations, initial information can be obtained when automatically adjusting the front seats. For example, when the vehicle detects a user approaching or unlocking the vehicle, it can automatically adjust the front seats to a preset position. That is, the vehicle can detect automatic trigger commands associated with the user in real time. These commands are used to automatically adjust the state of the front seats or rear display devices, and the initial information can be determined based on these commands. For instance, when detecting information such as the user's weight distribution and posture to automatically adjust the front seats, the automatic trigger command can be obtained based on this information, thus acquiring the initial information.
[0089] S402, based on the first data, determine a first positional relationship and / or a second positional relationship, wherein the first positional relationship is the positional relationship between a first obstacle in the lowering area of the rear display device and the rear display device, and the second positional relationship is the positional relationship between a second obstacle in the active area of the front seat and the front seat.
[0090] In some implementations, the first data includes first distance data collected by a distance sensor. When the first information is used to instruct the lowering of the rear display device, S402 can be refined to: determining the positional relationship between the first part of the rear display device and the first obstacle based on the first distance data collected by the distance sensor, wherein the first part of the rear display device includes the lower edge of the rear display device.
[0091] It is understandable that, during the lowering of the rear display device, there is a high probability that the lower edge of the rear display device will collide with the first obstacle. Therefore, the positional relationship between the first part of the rear display device and the first obstacle can be determined. Determining the positional relationship between the first part of the rear display device and the first obstacle can also be understood as determining that a first obstacle exists in the lowering area of the rear display device. Of course, in some other embodiments, the first part may also include other parts of the rear display device. For example, for rear display devices that open and close by rotation, such as ceiling-mounted displays, the first part may also be the plane on which the display panel is located. Here, the first part is not limited. The following will combine... Figures 5 to 8 Please provide a detailed explanation.
[0092] Figure 5 A schematic diagram of the arrangement of a distance sensor according to an embodiment of this application is shown. Wherein, Figure 5 (a) shows a front view of the front seats. Figure 5 (b)-(g) show the side views of the front seats. Figure 5 In (b)-(h), the area where the rear display device is placed is indicated by a dashed rectangle. Figure 5 The distance sensor shown detects the distance in the vehicle's height direction. Wherein, Figure 5 (b) shows the situation where the front seats are not in the area where the rear display device is lowered. Figure 5 (c) shows the situation where the front seats move backward, causing them to enter the area where the rear display device is placed. Figure 5 (d) and (e) show the situation where the front seats are adjusted back so that they enter the lower area of the rear display unit. Figure 5 (f) shows the situation where the front seats are in the lower area of the rear display device because the front seat tray table is in the open position. Figure 5 (g) shows a situation where the rear passenger is in a forward-leaning position, causing the rear passenger to enter the lowering area of the rear display device. Figure 5 (h) shows a situation where items hanging from the back of the front seat are placed in the lower area of the rear display device.
[0093] It should be understood that the area for lowering the rear display device includes the path for lowering the rear display device. In order to reserve a certain safety space, the lowering area can be extended outward by a certain distance according to the lowering path. If a first obstacle enters the lowering area, it can be considered that it will hinder the lowering of the rear display device.
[0094] like Figure 5As shown in (a) of this application, in some embodiments, a distance sensor may be provided in the vehicle top area above the front seats.
[0095] For example, the area above the front seat on the vehicle top can be the roof.
[0096] For example, the area above the front seat on the vehicle roof could be a storage device for a projection screen.
[0097] As described above, the presence of a first obstacle in the lowering area of the rear display device can be determined based on the magnitude of the first distance data.
[0098] like Figure 5 As shown in (b), when the front seats are not in the area where the rear display device is lowered, the distance sensor detects distance d as the distance between the distance sensor and the vehicle floor (or it can also be understood as the distance between the vehicle roof and the vehicle floor).
[0099] like Figure 5 As shown in (c), when the front seat is moved backward so that it enters the lowering area of the rear display device, the distance d detected by the distance sensor is the distance between the distance sensor and the front seat.
[0100] It should be noted that, in Figure 5 In the example shown in (c), distance d is the distance between the distance sensor and the headrest of the front seat. However, this embodiment is not limited to this. In some other examples, when the front seat is moved backward so that it enters the lower area of the rear display device, the distance sensor is configured to detect distance d as the distance between the distance sensor and the back of the front seat.
[0101] like Figure 5 As shown in (d) and (e), when the backrest of the front seat is adjusted backward so that the front seat enters the area where the rear display device is placed, the distance d detected by the distance sensor is the distance between the distance sensor and the front seat, such as the distance between the distance sensor and the backrest of the front seat, or the distance between the distance sensor and the headrest of the front seat.
[0102] like Figure 5 As shown in (f), the front seats can be equipped with tables. When the table is in the open position, it will be placed in the area below the rear display device. In this case, the distance d detected by the distance sensor is the distance between the distance sensor and the table.
[0103] like Figure 5As shown in (g), rear passengers may be leaning forward while riding in the vehicle, thus entering the lower area of the rear display device. In this case, the distance d detected by the distance sensor is the distance between the distance sensor and the rear passenger.
[0104] like Figure 5 As shown in (h), the back of the front seats can be equipped with hooks for hanging items. The hung items may extend into the lower area of the rear display unit; in this case, the distance d detected by the distance sensor is the distance between the distance sensor and the hung item.
[0105] pass Figure 5 It can be seen that the distance data detected by the distance sensor when there is no first obstacle in the area where the rear display device is lowered is greater than the distance data detected when there is a first obstacle in the area where the rear display device is lowered. Therefore, a preset distance range 1 can be set. If the distance data detected by the distance sensor is within this range 1, it can be determined that there is a first obstacle in the area where the rear display device is lowered. Alternatively, the distance between the distance sensor and the floor can be set as a threshold 1. If the distance data detected by the distance sensor is less than this threshold 1, it can be determined that there is a first obstacle in the area where the rear display device is lowered. This first obstacle can be the front seat, the rear passenger, or an item hanging on the back of the front seat, etc.
[0106] In some embodiments, the distance between the front seat and the distance sensor in various positions can be calibrated based on different rotation angles of the front seat backrest and different longitudinal positions of the front seat, thereby obtaining the preset distance range of the aforementioned embodiments. That is, the possible position of the seat can be obtained based on this distance range and the distance data measured in real time by the distance sensor, and then the positional relationship between the first part of the rear display device and the first obstacle can be determined based on the magnitude of the first distance data.
[0107] exist Figure 5 The example shown uses a distance sensor located in the vehicle roof area above the front seats, but this embodiment is not limited to this, and the distance sensor can also be located in other positions.
[0108] Figure 6 A schematic diagram of another distance sensor arrangement provided in an embodiment of this application is shown. Wherein, Figure 6 Images (a)-(f) show side views of the front seats. Figure 6 In (a)-(f), the area where the rear display device is placed is indicated by a dashed rectangle. Figure 6 The distance sensor shown detects the distance in the vehicle's height direction. Wherein, Figure 6(a) shows the situation where the front seats are not in the area where the rear display device is lowered. Figure 6 (b) shows a situation where the front seats are positioned so that the front seats are in the lower area of the rear display unit because the front seat tray tables are open. Figure 6 (c) shows a situation where the rear passenger is in a forward-leaning position, causing the rear passenger to enter the lowering area of the rear display device. Figure 6 (d) shows the situation where the front seats are adjusted backwards, causing them to enter the area where the rear display device is lowered. Figure 6 (e) shows the situation where the front seats move backward, causing them to enter the area where the rear display unit is lowered. Figure 6 (f) shows a situation where items hanging from the back of the front seat are placed in the lower area of the rear display device.
[0109] like Figure 6 As shown, in some embodiments of this application, a distance sensor may be provided in the lower edge area of the rear display device.
[0110] As described above, the presence of a first obstacle in the lowering area of the rear display device can be determined based on the magnitude of the first distance data.
[0111] like Figure 6 As shown in (a), when the front seats are not in the lowering area of the rear display device, the distance sensor detects distance d as the distance between the distance sensor and the vehicle floor.
[0112] like Figure 6 As shown in (b), the front seats can be equipped with tables. When the table is in the open position, it will be placed in the lower area of the rear display device. In this case, the distance d detected by the distance sensor is the distance between the distance sensor and the table.
[0113] like Figure 6 As shown in (c), rear passengers may be leaning forward while riding in the car, thus entering the lower area of the rear display device. In this case, the distance d detected by the distance sensor is the distance between the distance sensor and the rear passenger.
[0114] like Figure 6 As shown in (d), when the backrest of the front seat is adjusted backward so that the front seat enters the area where the rear display device is placed, the distance d detected by the distance sensor is the distance between the distance sensor and the front seat.
[0115] like Figure 6As shown in (e), when the front seat is moved backward so that it enters the lowering area of the rear display device, the distance d detected by the distance sensor is the distance between the distance sensor and the front seat.
[0116] like Figure 6 As shown in (f), the back of the front seats can be equipped with hooks for hanging items. The suspended items may extend into the lower area of the rear display unit; in this case, the distance d detected by the distance sensor is the distance between the distance sensor and the suspended item.
[0117] pass Figure 6 It can be seen that the first distance data detected by the distance sensor when there is no first obstacle in the lowering area of the rear display device is greater than the first distance data detected by the distance sensor when there is a first obstacle in the lowering area of the rear display device. Therefore, a preset distance range 2 can be set. If the first distance data detected by the distance sensor is within this distance range 2, it can be determined that there is a first obstacle in the lowering area of the rear display device. Alternatively, the distance between the distance sensor and the floor can be set as a threshold 2. If the first distance data detected by the distance sensor is less than this threshold 2, it can be determined that there is a first obstacle in the lowering area of the rear display device.
[0118] In some embodiments, the distance between the front seat and the distance sensor in various positions can be calibrated based on different rotation angles of the front seat backrest and different longitudinal positions of the front seat, thereby obtaining the preset distance range of the aforementioned embodiments. That is, the possible position of the seat can be obtained based on this distance range and the distance data measured in real time by the distance sensor, and then the positional relationship between the first part of the rear display device and the first obstacle can be determined based on the magnitude of the first distance data.
[0119] Figure 7 A schematic diagram of another distance sensor arrangement provided in an embodiment of this application is shown. Wherein, Figure 7 The left side of (a)-(c) shows a side view of the front seat. Figure 7 The right side of (a)-(c) shows a top view of the front seat. Figure 7 The distance sensor shown detects in the width direction of the vehicle. Wherein, Figure 7 (a) shows the situation where the front seats are not in the area where the rear display device is lowered. Figure 7 (b) shows the situation where the front seats move backward, causing them to enter the area where the rear display unit is placed. Figure 7(c) shows the situation where the front seats are adjusted backwards so that they enter the lower area of the rear display device.
[0120] As described above, when the front seats are adjusted backward, they may move into the area where the rear display device is located. Therefore, the position of the distance sensor in the center pillar can be configured accordingly.
[0121] like Figure 7 As shown in (a)-(c), the distance sensor can be configured such that when the front seat is not in the lowering area of the rear display device, the distance detected by the distance sensor is the distance between the distance sensor and the center pillar on the other side; and when the front seat is in the lowering area of the rear display device, the distance detected by the distance sensor is the distance between the distance sensor and the center pillar on the other side. Since the distance between the distance sensor and the center pillar on the other side and the distance between the distance sensor and the front seat are known, it is possible to determine whether the first distance data detected by the distance sensor is the distance between the distance sensor and the center pillar on the other side or the distance between the distance sensor and the front seat based on the magnitude of the first distance data detected by the distance sensor, and thus determine whether there is a first obstacle in the lowering area of the rear display device.
[0122] exist Figures 5 to 7 In the example shown, where the rear display device is a projection screen, in other embodiments of this application, the rear display device can also be a ceiling-mounted display screen. When the rear display device is a ceiling-mounted display screen, lowering the rear display device requires folding it.
[0123] Figure 8 A schematic diagram of another distance sensor arrangement provided in an embodiment of this application is shown. Wherein, Figure 8 Images (a)-(d) show side views of the front seats. Figure 8 (a) shows the situation where the front seats are not in the area where the rear display device is lowered. Figure 8 (b) shows the situation where the front seats move backward, causing them to enter the area where the rear display unit is placed. Figure 8 (c) shows the situation where the front seats are adjusted back so that they enter the lower area of the rear display device. Figure 8 (d) shows a situation where the rear passenger enters the lowering area of the rear display device because the rear passenger is in a forward-leaning position.
[0124] like Figure 8 As shown, in some embodiments of this application, a distance sensor may be provided in the lower edge area of the rear display device.
[0125] It is understandable that, assuming there is no first obstacle in the area where the rear display device is lowered, the distance detected by the distance sensor at each folding angle should be within a preset distance range. Therefore, a mapping relationship between each folding angle and distance can be established. When the distance detected by the distance sensor at one or more folding angles is not within the preset distance range, it can be determined that there is a first obstacle in the area where the rear display device is lowered.
[0126] For example, such as Figure 8 As shown in (a), when the folding angle of the rear display device is a and the distance detected by the distance sensor is d1, if d1 is within the preset distance range, it is determined that the front seat has not entered the lowering area of the rear display device.
[0127] like Figure 8 As shown in (b), when the front seat moves backward, it enters the lowering area of the rear display device. At this time, when the folding angle of the rear display device is a, the distance detected by the distance sensor is d2. This d2 is not within the preset distance range, indicating that there is a first obstacle in the lowering area.
[0128] like Figure 8 As shown in (c), when the front seat back is adjusted backward so that the front seat enters the lowering area of the rear display device, when the folding angle of the rear display device is a, the distance detected by the distance sensor is d3. This d3 is not within the preset distance range, indicating that there is a first obstacle in the lowering area.
[0129] like Figure 8 As shown in (d), when the rear passenger is in a forward-leaning state, the rear passenger enters the lowering area of the rear display device. At this time, when the folding angle of the rear display device is a, the distance detected by the distance sensor is d4. This d4 is not within the preset distance range, indicating that there is a first obstacle in the lowering area.
[0130] In some embodiments, the distance between the rear-seat display device at different lowering progresses (e.g., different folding angles, different lowering distances), the front seat backrest at different rotation angles, and the front seat at different longitudinal positions can be calibrated to determine the distance between the rear-seat display device at different lowering progresses and the front seat in various positions, thereby obtaining the preset distance range of the aforementioned embodiments. That is, the possible positions of the seat can be obtained based on this distance range and the distance data measured in real time by the distance sensor, and the positional relationship between the first part of the rear-seat display device and the first obstacle can be determined based on the magnitude of the first distance data.
[0131] In some implementations, the first data includes a first image captured by an image sensor. When the first information is used to instruct the placement of the rear-seat display device, S402 can be refined as follows: Based on the first image captured by the image sensor, determine second information, which includes one or more of the following: angle information of the front seat backrest, position information of the front seat, area ratio of the front seat in the first image, opening / closing information of the front seat tray table, position information of the rear-seat user, information on items suspended from the back of the front seat, and displacement information of the front seat; determine the positional relationship between the first part of the rear-seat display device and the first obstacle based on the second information. The following will combine... Figure 9 and Figure 10 Please provide a detailed explanation.
[0132] Figure 9 This illustration shows a schematic diagram of an image acquired by an image sensor according to an embodiment of this application. Figure 9 In the example shown, the image sensor acquires an image of the side of the front seat, where, Figure 9 (a) shows the situation where the front seats are not in the area where the rear display device is lowered. Figure 9 (b) shows the situation where the front seats move backward, causing them to enter the area where the rear display unit is placed. Figure 9 (c) shows the situation where the front seats are adjusted back so that they enter the lower area of the rear display device. Figure 9 (d) shows the situation where the front seats are in the lower area of the rear display device because the front seat tray table is in the open position. Figure 9 (e) shows a situation where the rear passenger is in a forward-leaning position, causing the rear passenger to enter the lowering area of the rear display device. Figure 9 (f) shows a situation where items hanging from the back of the front seat are placed in the lower area of the rear display device.
[0133] Similar to the analysis above, when the front seats are adjusted backward, items are hanging from the back of the front seats, the rear passengers are leaning forward, or the front seat tray tables are open, these could all be the first obstacles to the lowering area of the rear display device. Therefore, one or more of the following can be determined based on the first image acquired by the image sensor: the angle information of the front seat backrest, the position information of the front seats, the area ratio of the front seats in the first image, the opening and closing information of the front seat tray tables, the position information of the rear users, the information of items hanging from the back of the front seats, and the displacement information of the front seats.
[0134] In some implementations, if it is determined from the first image that the angle of the backrest of the front seat is greater than a threshold 3, then it is determined that the front seat has entered the lowering area of the rear display device.
[0135] In one example, the threshold 3 can be determined by continuously adjusting the angle of the seat back without moving the front seat backward. In other words, if the angle of the front seat back is less than or equal to the threshold 3 without moving the front seat backward, the front seat has not entered the lowering area of the rear display device; if the angle of the front seat back is greater than the threshold 3, the front seat has entered the lowering area of the rear display device.
[0136] In some implementations, since the image sensor is fixed, the lowering area of the rear display device in the first image is also fixed. If it is determined from the first image that the front seat overlaps with the lowering area of the rear display device in the first image, then it is determined that the front seat has entered the lowering area of the rear display device.
[0137] In some implementations, if the area proportion of the front seat in the first image is determined to be greater than a threshold of 4, then the front seat is determined to have entered the lowering area of the rear display device. It is understandable that in this implementation, the first image captures a portion of the front seat; as the front seat moves backward, its area proportion in the first image gradually increases. Therefore, the area proportion of the front seat in the first image can be used to determine whether the front seat has entered the lowering area of the rear display device.
[0138] In some implementations, if it is determined from the first image that the front seat table is in an open state, then it is determined that the front seat has entered the lowering area of the rear display device.
[0139] In some implementations, since the image sensor is fixed, the lowering area of the rear display device in the first image is also fixed. If it is determined from the first image that the rear passenger overlaps with the lowering area of the rear display device in the first image, then it is determined that the rear passenger has entered the lowering area of the rear display device.
[0140] In some implementations, since the image sensor is fixed, the lowering area of the rear display device in the first image is also fixed. If it is determined from the first image that the item hanging on the back of the front seat overlaps with the lowering area of the rear display device in the first image, then it is determined that the item hanging on the back of the front seat has entered the lowering area of the rear display device.
[0141] In some implementations, since the image sensor is fixed, the position of the seat cushion in the image obtained when the front seat has not moved backward can be used as a reference position. Then, the actual displacement of the front seat can be determined based on the deviation between the position of the front seat cushion in the first image and the reference position. When the displacement of the front seat is greater than a threshold of 5, it can be determined that the front seat has entered the lowering area of the rear display device.
[0142] In some embodiments, images of the front seats in different positions can be acquired and it can be determined whether the front seats interfere with the rear display device in different positions. Then, the positional relationship between the first part of the rear display device and the first obstacle can be determined based on the first image acquired in real time.
[0143] In this embodiment of the application, for the purposes of... Figure 9 The method for determining the first information from the first image shown is not specifically limited. For example, image recognition technology can be used to identify the front seat, various components of the front seat (such as headrest, seat back, table, and cushion), rear passengers, and items hanging on the back of the front seat in the first image. In this way, the angle information of the front seat back, the position information of the front seat, the area ratio of the front seat in the first image, the opening and closing information of the front seat table, the position information of the rear users, the information of items hanging on the back of the front seat, and the displacement information of the front seat can be determined.
[0144] Figure 10 This illustration shows a schematic diagram of an image acquired by another image sensor provided in an embodiment of this application. Figure 10 In the example shown, the image sensor acquires images from above the front seats. Figure 10 (a) shows the situation where the front seats are not in the area where the rear display device is lowered. Figure 10 (b) shows the situation where the front seats are adjusted back so that they enter the lower area of the rear display unit. Figure 10 (c) shows the situation where the front seats move backward, causing them to enter the area where the rear display device is placed. Figure 10 (d) shows a situation where the front seat is positioned so that it extends into the area where the rear display unit is lowered due to the front seat tray table being open. It is understood that the image sensor capturing images from above the front seat can also determine the position of the rear passengers and information about items hanging from the back of the front seat. Figure 10 (Not shown in the image).
[0145] Similar to the analysis above, when the front seats are adjusted backward, items are hanging from the back of the front seats, the rear passengers are leaning forward, or the front seat tray tables are open, these could all be the first obstacles to the lowering area of the rear display device. Therefore, one or more of the following can be determined based on the first image acquired by the image sensor: the angle information of the front seat backrest, the position information of the front seats, the area ratio of the front seats in the first image, the opening and closing information of the front seat tray tables, the position information of the rear users, the information of items hanging from the back of the front seats, and the displacement information of the front seats.
[0146] It should be understood that, regarding Figure 10 For a detailed description, please refer to the above text. For the sake of brevity, it will not be repeated here.
[0147] In this embodiment of the application, for the purposes of... Figure 10 The method for determining the second information from the first image shown is not specifically limited. For example, image recognition technology can be used to identify the front seat, various components of the front seat (such as headrest, backrest, table, and cushion), rear passengers, and items hanging on the back of the front seat in the first image. This can then determine the angle information of the front seat backrest, the position information of the front seat, the area ratio of the front seat in the first image, the opening and closing information of the front seat table, the position information of the rear users, the information of items hanging on the back of the front seat, and the displacement information of the front seat.
[0148] It should be noted that, due to Figure 9 The image is taken from the side of the front seat. After identifying the seat cushion and seat back, the angle between the seat cushion and seat back can be determined, that is, the angle of the front seat back. Figure 10 The image is taken from above the front seats. Therefore, when determining the angle information of the front seat backrest, for example, since the headrest moves backward when the seat backrest is adjusted, the position relationship between the headrest and the seat cushion in the image taken when the front seat backrest is not adjusted can be used as a reference positional relationship. Then, based on the position relationship between the headrest and the seat cushion in the first image and the reference positional relationship, the displacement of the headrest in the vehicle's length direction caused by adjusting the seat backrest is determined. Then, the angle of the seat backrest is determined based on the mapping relationship between the displacement of the headrest in the vehicle's length direction and the seat backrest angle. The mapping relationship between the displacement of the headrest in the vehicle's length direction and the seat backrest angle can be preset.
[0149] The previous section introduced the use of the first information to instruct the lowering of the rear display device, which is for the scenario of lowering the rear display device. The following section will introduce the use of the first information to instruct the adjustment of the front seats. The adjustment of the front seats can be either adjusting the front seats backward or adjusting the front seats forward.
[0150] In some implementations, the first data includes second distance data collected by a distance sensor. When the first information is used to indicate adjustment of the front seat and the rear display device is in a lowered state, S402 can be refined to: determine the positional relationship between a first part of the front seat and a second obstacle based on the second distance data collected by the distance sensor. The first part of the front seat includes any one or more of the following: a headrest of the front seat, a seat back of the front seat, a table on the back of the front seat, and items suspended from the back of the front seat. The following will combine... Figures 11-16 An introduction will be given, in which, Figures 11-15 This shows the front seats being adjusted backwards. Figure 16 This shows the front seats being adjusted forward.
[0151] It should be noted that the rear display device being in a lowered state can mean that the rear display device has been fully lowered or not. This application embodiment is not limited to this.
[0152] In one example, when the rear display device is in the lowered position, in order to protect the rear display device from collision, when the front seat is adjusted backward, if the front seat enters the lowered area of the rear display device, the front seat cannot be adjusted backward further. Therefore, when the front seat enters the lowered area of the rear display device, the rear display device can be understood as a second obstacle in the movement area of the front seat.
[0153] Figure 11 A schematic diagram of another distance sensor arrangement provided in an embodiment of this application is shown. Wherein, Figure 11 (a) shows a front view of the front seats. Figure 11 (b)-(e) show the side views of the front seats. Figure 11 The distance sensor shown detects the distance in the vehicle's height direction. Wherein, Figure 11 (b) shows a situation where the front seats can be adjusted backward because the front seats have not been moved into the area where the rear display device is lowered. Figure 11 (c) shows a situation where the front seats cannot be adjusted further back because they have moved backward into the area where the rear display unit is located. Figure 11 (d) shows the situation where the front seat cannot be further adjusted backward because the front seat has been adjusted backward into the area where the rear display device is located. Figure 11 (e) shows a situation where the front seat cannot be adjusted further back because an item is hanging on the back of the front seat and the item hangs in the lower area of the rear display device.
[0154] It should be understood that, regarding Figure 11 The description of (a) in the text can be found above, and will not be repeated here.
[0155] like Figure 11 As shown in (b), when the front seat is not in the lowering area of the rear display device, the distance sensor detects that the distance d is the distance between the distance sensor and the vehicle floor. In this case, even if the rear display device is in the activity area of the front seat, the front seat can still be adjusted backward because the two are far apart.
[0156] like Figure 11 As shown in (c), when the front seat is moved backward so that it enters the area where the rear display device is placed, the front seat can no longer be moved backward. The distance d detected by the distance sensor is the distance between the distance sensor and the front seat.
[0157] like Figure 11 As shown in (d), when the backrest of the front seat is adjusted backward so that the front seat enters the lower area of the rear display device, the front seat can no longer be adjusted backward. The distance d detected by the distance sensor is the distance between the distance sensor and the front seat.
[0158] like Figure 11 As shown in (e), the back of the front seats can be equipped with hooks for hanging items. The suspended item may enter the lower area of the rear display unit. In this case, the front seats can no longer be adjusted backward, and the distance d detected by the distance sensor is the distance between the distance sensor and the suspended item.
[0159] pass Figure 11It can be seen that the second distance data detected by the distance sensor when the front seat is not in the lowering area of the rear display device is greater than the second distance data detected when the front seat is in the lowering area of the rear display device. Therefore, a preset distance range 3 can be set. If the second distance data detected by the distance sensor is within this range 3, it can be determined that the front seat has entered the lowering area of the rear display device. Consequently, when the rear display device is in the lowered state, the positional relationship between the rear display device and the front seat is relatively close, and the rear display device will obstruct the movement of the front seat. Alternatively, the distance between the distance sensor and the floor can be set to a threshold 6. If the second distance data detected by the distance sensor is less than this threshold 6, it can be determined that the front seat has entered the lowering area of the rear display device. Consequently, when the rear display device is in the lowered state, the positional relationship between the rear display device and the front seat is relatively close, and the rear display device will obstruct the movement of the front seat.
[0160] In some embodiments, the distance between the front seat and the distance sensor in various poses can be determined based on the different rotation angles of the front seat backrest and the different longitudinal positions of the front seat, thereby obtaining the preset distance range of the aforementioned embodiment. That is, the possible pose of the seat can be obtained based on the distance range and the distance data measured in real time by the distance sensor, and the positional relationship between the first part of the front seat and the second obstacle can be determined based on the magnitude of the second distance data.
[0161] Figure 11 The distance sensor is located in the vehicle's roof area above the front seats. The distance sensor can also be placed in other locations, such as the center pillar. Figure 7 As shown in (a)-(c), the distance sensor can be configured such that when the rear display device is not in the lowering area, the distance detected by the distance sensor is the distance between the distance sensor and the center pillar on the other side; and when the front seat is in the lowering area of the rear display device, the distance detected by the distance sensor is the distance between the distance sensor and the front seat. Since the distance between the distance sensor and the center pillar on the other side and the distance between the distance sensor and the front seat are known, it is possible to determine whether the second distance data detected by the distance sensor is the distance between the distance sensor and the center pillar on the other side or the distance between the distance sensor and the front seat based on the magnitude of the second distance data detected by the distance sensor. Therefore, when the rear display device is in the lowering state and the front seat is in the lowering area of the rear display device, it can be determined that the positional relationship between the rear display device and the front seat is too close, and the rear display device will obstruct the movement of the front seat.
[0162] Figure 12 A schematic diagram of another distance sensor arrangement provided in an embodiment of this application is shown. Wherein, Figure 12 Images (a)-(c) show side views of the front seats. Figure 12 The distance sensor shown detects along the length of the vehicle. Figure 12 (a) shows a situation where the front seats can be adjusted backward because the front seats have not been moved into the area where the rear display unit is lowered. Figure 12 (b) shows a situation where the front seats cannot be adjusted further back because they have moved backward into the area where the rear display unit is located. Figure 12 (c) shows a situation where the front seat cannot be adjusted further back because the front seat is moved into the lower area of the rear display device due to the adjustment of the front seat backrest.
[0163] like Figure 12 As shown, a distance sensor can be placed on the side of the front seat closest to the rear seat (such as the side of the front seat headrest closest to the rear seat).
[0164] As described above, the presence of a second obstacle in the front seat's activity area can be determined based on the magnitude of the second distance data.
[0165] like Figure 12 As shown in (a)-(c), when the front seat is adjusted backward, the distance detected by the distance sensor located on the side of the front seat closest to the rear seat gradually decreases. Therefore, when using... Figure 12 In the case of the distance sensor arrangement shown, a threshold 7 can be preset. When the distance detected by the distance sensor is greater than the threshold 7, it indicates that the front seat has not entered the lowering area of the rear display device, and the front seat can continue to be adjusted backward, that is, the position relationship between the rear display device and the front seat is far. When the distance detected by the distance sensor is less than or equal to the threshold 7, it indicates that the front seat has entered or is about to enter the lowering area of the rear display device, and the front seat cannot continue to be adjusted backward, that is, the position relationship between the rear display device and the front seat is close.
[0166] In some embodiments, the distance between the rear seat and the distance sensor can be calibrated based on the different lowering progress of the rear display device and the various positions of the front seat at different lowering progresses. This allows for the determination of the threshold value described in the previous embodiment. Based on this threshold value and the distance data measured in real time by the distance sensor, the possible positions of the seat and the rear display device can be obtained. Furthermore, the positional relationship between the first part of the front seat and the second obstacle can be determined based on the magnitude of the second distance data.
[0167] Figure 13A schematic diagram of another distance sensor arrangement provided in an embodiment of this application is shown. Wherein, Figure 13 Images (a)-(c) show side views of the front seats. Figure 13 The distance sensor shown detects along the length of the vehicle. Figure 13 (a) shows a situation where the front seats can be adjusted backward because the front seats have not been moved into the area where the rear display unit is lowered. Figure 13 (b) shows a situation where the front seats cannot be adjusted further back because they have moved backward into the area where the rear display unit is located. Figure 13 (c) shows a situation where the front seat cannot be adjusted further back because the front seat is moved into the lower area of the rear display device due to the adjustment of the front seat backrest.
[0168] like Figure 13 As shown, a distance sensor can be placed at the lower edge of the rear display device.
[0169] As described above, the presence of a second obstacle in the front seat's activity area can be determined based on the magnitude of the second distance data.
[0170] like Figure 13 As shown in (a)-(c), when the front seats are adjusted backward, the distance detected by the distance sensor located at the lower edge of the rear display device gradually decreases. Therefore, when using... Figure 13 In the case of the distance sensor arrangement shown, a threshold 8 can be preset. When the distance detected by the distance sensor is greater than the threshold 8, it indicates that the front seat has not entered the lowering area of the rear display device, and the front seat can continue to be adjusted backward, that is, the position relationship between the rear display device and the front seat is far. When the distance detected by the distance sensor is less than or equal to the threshold 8, it indicates that the front seat has entered or is about to enter the lowering area of the rear display device, and the front seat cannot continue to be adjusted backward, that is, the position relationship between the rear display device and the front seat is close.
[0171] In some embodiments, the distance between the front seat and the distance sensor can be calibrated based on the different lowering progress of the rear display device and the various positions of the front seat at different lowering progresses. This allows the threshold value of the aforementioned embodiment to be obtained. Based on this threshold value and the distance data measured in real time by the distance sensor, the possible positions of the seat and the rear display device can be obtained. Furthermore, the positional relationship between the first part of the front seat and the second obstacle can be determined based on the magnitude of the second distance data.
[0172] In some implementations, the first data includes a second image captured by an image sensor. When the first information is used to instruct adjustment of the front seat and the rear display device is in a lowered state, S402 can be refined to: determine third information based on the second image captured by the image sensor. The third information includes one or more of the following: the angle information of the front seat backrest, the position information of the front seat, the area ratio of the front seat in the first image, the opening / closing information of the front seat table, the position information of the rear user, and information on items suspended from the back of the front seat; and determine the positional relationship between the first part of the front seat and the second obstacle based on the third information. The following will combine... Figure 14 and Figure 15 Please provide a detailed explanation.
[0173] Figure 14 This illustration shows a schematic diagram of an image acquired by another image sensor provided in an embodiment of this application. Figure 14 In the example shown, the image sensor acquires an image of the side of the front seat, where, Figure 14 (a) shows a situation where the front seats can be adjusted backward because the front seats have not been moved into the area where the rear display unit is lowered. Figure 14 (b) shows the situation where the front seats move backward, causing them to enter the area where the rear display unit is placed. Figure 14 (c) shows a situation where the front seat cannot be further adjusted backward because the front seat has been adjusted backward to enter the area where the rear display device is located. Figure 14 (d) shows a situation where the front seat cannot be adjusted further back because the items hanging on the back of the front seat have entered the lower area of the rear display device.
[0174] Figure 15 This illustration shows a schematic diagram of an image acquired by another image sensor provided in an embodiment of this application. Figure 15 In the example shown, the image sensor acquires images from above the front seats, where, Figure 15 (a) shows a situation where the front seats can be adjusted backward because the front seats have not been moved into the area where the rear display unit is lowered. Figure 15 (b) shows the situation where the front seats move backward, causing them to enter the area where the rear display unit is placed. Figure 15 (c) shows a situation where the front seat cannot be further adjusted backward because the front seat has been adjusted backward to enter the area where the rear display device is located. Figure 15(d) shows a situation where the front seat cannot be adjusted further back because the items hanging on the back of the front seat have entered the lower area of the rear display device.
[0175] It should be understood that, regarding Figure 14 and Figure 15 For a detailed description, please refer to the above text. For the sake of brevity, it will not be repeated here.
[0176] In some embodiments, images of the front seat in different positions can be acquired when the rear display device is in a lowered state, and whether the rear display device will obstruct the front seat can be determined. Then, the positional relationship between the first part of the front seat and the second obstacle can be determined based on the real-time acquired second image.
[0177] In some implementations, the rear-seat display device can be lowered while the front seatback tray table remains open. For example, if the rear-seat display device is partially lowered, its lower edge may not align with the tray table. Alternatively, if the rear-seat display device is small in the vehicle's height direction, even when fully lowered, it may not reach the tray table position. However, if the front seatback is adjusted forward, the tray table edge will move upwards, and the rear-seat display device may still be a second obstacle in the front seat's movement area. In such cases, the positional relationship between the second obstacle and the front seat can still be determined using second distance data collected by a distance sensor and / or a second image collected by an image sensor. The following section will discuss this further. Figure 16 Please provide an explanation.
[0178] Figure 16 A schematic diagram of another distance sensor arrangement provided in an embodiment of this application is shown. Figure 16 Images (a) and (b) show side views of the front seats. Figure 16 The distance sensor shown detects the distance in the vehicle's height direction. Wherein, Figure 16 (a) shows a situation where the front seats have their tray tables off and the rear display is in the lowered position, so there are no second obstacles in the front seat's movement area when the seatback is adjusted forward. Figure 16 (b) shows a situation where the front seat has its table up and the rear display is in the lowered position, so when the seat back is adjusted forward, there is a second obstacle (i.e., the rear display) in the area where the front seat can move.
[0179] like Figure 16 As shown, in some embodiments of this application, a distance sensor can be installed in the vehicle top area above the front seats.
[0180] like Figure 16As shown in (a), when the front seats are not in the area where the rear display device is lowered and the table is closed, the distance detected by the distance sensor is the distance between the distance sensor and the floor.
[0181] like Figure 16 As shown in (b), when the front seats are not in the lowering area of the rear display device and the table is in the open state, the distance detected by the distance sensor is the distance between the distance sensor and the table.
[0182] It is understandable that if the front seats move into the area where the rear display device is placed, the distance detected by the distance sensor can be the distance between the distance sensor and the headrest or seat back, which is less than the distance between the distance sensor and the table.
[0183] In summary, if the second distance data is determined to be the distance between the distance sensor and the table based on the magnitude of the second distance data collected by the distance sensor, and the rear display device is in the lowered state, then the rear display device can be identified as the second obstacle in the movable area of the seat back of the front seat that is being adjusted forward.
[0184] In some implementations, it can be determined whether the table is open based on the second image. If it is determined from the second image that the table is open and the rear display device is in the lowered state, it can be determined that the rear display device is the second obstacle in the movable area of the seat back of the front seat that is being adjusted forward.
[0185] In some implementations, when the first information is used to instruct the lowering of the rear display device and the adjustment of the front seats, S402 can be refined to: determining the positional relationship between the first part of the rear display device and the first obstacle based on the first data, and determining the positional relationship between the first part of the front seat and the second obstacle based on the first data, wherein the first data includes third distance data collected by a distance sensor and / or a third image collected by an image sensor.
[0186] It should be understood that the descriptions of determining the positional relationship between the first part of the rear display device and the first obstacle based on the first data, and the descriptions of determining the positional relationship between the first part of the front seat and the second obstacle based on the first data, can be found above and will not be repeated here.
[0187] It should also be understood that in some situations, both the front seats can be adjusted and the rear display device can be lowered. In these cases, the primary and secondary positional relationships are monitored in real time to determine if there is a risk of interference. For example, a user's voice command is detected: "Move the front seats back and lower the rear display device."
[0188] In one example, there is no first obstacle in the area where the rear display device is lowered, meaning the front seat does not enter the area where the rear seat is lowered. In this example, the front seat can be adjusted backward and the rear display device can be lowered. During the process of adjusting the front seat backward and lowering the rear display device, the front seat may enter the area where the rear seat is lowered. In this case, the front seat becomes the first obstacle to the rear display device, and the rear display device becomes the second obstacle to the front seat.
[0189] S403, adjust the state of the front seats or rear display devices according to the first positional relationship and / or the second positional relationship.
[0190] In some implementations, where the first information is used to instruct the lowering of the rear display device, S403 can be refined to: adjusting the state of the front seats and / or the rear display device according to the first positional relationship.
[0191] In one example, the state of the front seats can be adjusted according to a first positional relationship. Adjusting the state of the front seats includes adjusting their position and the angle of their backrests. In this example, after adjusting the state of the front seats, the rear display device can be lowered.
[0192] For example, such as Figure 5 (c) Figure 6 (e) Figure 7 (b) Figure 8 (b) Figure 9 (b) and Figure 10 As shown in (c), the front seats can be moved forward so that they are removed from the area where the rear display device is placed.
[0193] For example, such as Figure 5 (d)-(e) Figure 6 (d) Figure 7 (c) Figure 8 (c) Figure 9 (c) Figure 10 As shown in (b), the backrest of the front seat can be adjusted forward so that the front seat moves away from the area where the rear display device is placed.
[0194] In another example, the state of the rear display device can be adjusted according to the first positional relationship. Adjusting the state of the rear display device includes adjusting the downward distance or folding angle of the rear display device.
[0195] For example, such as Figure 5 (f) in Figure 6As shown in (b), assuming the maximum lowering distance of the rear display device is D, when it is determined that there is a table in the lowering area of the rear display device, and the distance is determined to be d, the lowering distance of the rear display device can be adjusted from D to d.
[0196] In some implementations, when the first information is used to indicate the adjustment of the front seats and the rear display device is in a lowered state, S403 can be refined to: adjust the state of the front seats and / or the rear display device according to the second positional relationship.
[0197] In one example, the state of the front seats can be adjusted based on the second positional relationship.
[0198] For example, such as Figure 11 (b) Figure 12 (a) Figure 13 (a) Figure 14 (a) Figure 15 As shown in (a), the front seat can be adjusted backward. When the front seat is adjusted to the boundary of the area where the rear display device is lowered, the adjustment of the front seat can be stopped, that is, the front seat is changed from dynamic to static.
[0199] In another example, the state of the rear display device can be adjusted according to the second positional relationship. Adjusting the state of the rear display device includes changing it from static to dynamic.
[0200] For example, such as Figure 11 (b) Figure 12 (a) Figure 13 (a) Figure 14 (a) Figure 15 As shown in (a), the front seats can be adjusted backwards, and when the front seats are adjusted to the boundary of the area where the rear display device is lowered, the rear display device can be folded up.
[0201] In some implementations, where the first information is used to instruct the lowering of the rear display device and the adjustment of the front seats, S403 can be further refined to: adjusting the state of the front seats and / or the rear display device according to the first positional relationship and the second positional relationship.
[0202] In one example, the state of the front seats can be adjusted based on a first positional relationship and a second positional relationship. Adjusting the state of the front seats includes adjusting the position of the front seats, the angle of the front seat backrests, and changing the front seats from a dynamic to a static position.
[0203] For example, such as Figure 5 (b) Figure 6 (a) Figure 7 (a) Figure 8 (a) Figure 9 (a) Figure 10 As shown in (a), the front seat can be adjusted backward and the rear display device can be lowered. Adjusting the front seat backward can be stopped when it reaches the boundary between the front seat and the lowering area of the rear display device. Since adjusting the front seat backward can be stopped when it reaches the boundary between the front seat and the lowering area of the rear display device, the rear display device can be fully lowered.
[0204] In another example, the state of the rear display device can be adjusted based on the first positional relationship and the second positional relationship.
[0205] For example, such as Figure 5 (b) Figure 6 (a) Figure 7 (a) Figure 8 (a) Figure 9 (a) Figure 10 As shown in (a), the front seats can be adjusted backward and the rear display device can be lowered. When the front seats are adjusted to the boundary of the area where the rear display device is lowered, the front seats can be adjusted backward further. Since the front seats have entered the area where the rear display device is lowered, the lowering of the rear display device can be stopped, or the rear display device can be folded up.
[0206] The interference detection method provided in this application can determine whether there is interference between the rear display device and the front seat by using data collected by a distance sensor and / or an image sensor. It has high detection accuracy and effectively avoids the risk of the front seat colliding with the rear display device when the rear display device is in the lowered state, as well as the risk of damage to the rear display device caused by the front seat being in the lowering area of the rear display device.

In addition to receiving the reflected light from the reflective interface, the infrared receiver 1720 can also receive ambient light. The infrared receiver 1730 is used to receive ambient light. Distance data is then determined based on the data collected by the infrared receivers 1720 and 1730, effectively eliminating ambient light interference and achieving ambient light interference suppression.
