JP-A-1-269106

In the conventional technology, the user who adjusts the position of the seat needs to visually check the seat in order to grasp the state of the seat that is the position adjustment target and the state of the passenger sitting on the seat. It was. For this reason, the line of sight must be frequently moved between the operation device such as the switch device and the sheet to be subjected to position adjustment, which is not convenient for the user. In addition, there is a range that becomes a blind spot from the position of the user who operates the operation device, and the shape of the luggage is deformed by adjusting the position of the seat without noticing the presence of the luggage placed in the range, etc. I was worried.
The present invention has been made in view of the above-described problem, and provides a technique capable of adjusting the position of a sheet while allowing a user to easily grasp the state of a sheet that is a position adjustment target and an object that operates with the sheet. The purpose is to provide.

  In order to achieve the above object, in the present invention, selection of a sheet to be subjected to position adjustment is received, image information indicating an image including an object that operates in accordance with the position adjustment of the selected sheet is acquired, A configuration is adopted in which the image is guided to the user based on the image information, a position adjustment instruction for the sheet by the user is received, and the sheet is operated in accordance with the position adjustment instruction. According to this configuration, when the selection of a sheet to be subjected to position adjustment is received, an image of an object that moves along with the position adjustment of the sheet is guided, so that the user can easily see the state of the object by looking at the image. Can grasp. The user can adjust the position of the sheet while easily grasping the state of the object. In addition, the sheet | seat which is the object of position adjustment in this invention is what is called a power seat comprised so that the position of a sheet | seat could be adjusted electrically.

  The sheet selection receiving unit only needs to be able to receive selection of a sheet to be subjected to position adjustment from among a plurality of sheets existing in the vehicle. That is, a sheet that is a candidate for position adjustment is presented and the user is allowed to select it. Various configurations such as buttons, switches, and touch panels can be adopted as modes for selection.

  The image information acquisition unit only needs to be able to acquire image information indicating an image including an object that moves in accordance with the position adjustment of the selected sheet. That is, it is only necessary that an image captured by a camera including the object corresponding to the sheet in the imaging range can be acquired after the user selection is received by the sheet selection receiving unit. As long as the camera that captures the image can include the object in the imaging range, the installation position and the number in the vehicle are arbitrary. For example, an image captured by a camera provided with a wide-angle lens provided at a position that includes the entire plurality of seats attached to the interior of the vehicle may be acquired, or the camera is zoomed in on the object and captured The acquired image may be acquired. Further, among a plurality of cameras attached to a plurality of locations for photographing the object from a plurality of angles, for example, a camera that photographs the object at a suitable angle according to the content of position adjustment is selected, and the camera A captured image may be acquired, or a plurality of images captured by a plurality of cameras may be acquired.

  The object that moves in accordance with the position adjustment of the sheet refers to the sheet itself that operates according to the position adjustment instruction (the entire sheet or a specific portion of the sheet) or an object that moves with the sheet. The object that moves together with the seat is an object that is supported by the seat or an object that is in contact with the seat, for example, the body of an occupant seated on the seat, luggage loaded on the seat, and leaning against the seat You may assume what is being done.

  The guide means only needs to be able to guide an image including the object to the user who adjusts the sheet based on the image information acquired by the image information acquisition means. That is, by displaying the image on the display using image information captured by the camera, the user is guided to the seat and the surroundings. Images taken by the camera may be displayed as they are, or the object and its surroundings may be cut out and enlarged for display. In the present invention, an operation unit for selecting a sheet to be subjected to position adjustment, a display unit for displaying the image, and an operation unit for a user to input a position adjustment instruction to be described later are provided for the user's line-of-sight movement. It is desirable that the range is provided within a range that does not become a burden.

The position adjustment instruction accepting unit only needs to accept a position adjustment instruction for the sheet by the user. The configuration can employ various configurations such as buttons, switches, and a touch panel in the same manner as the sheet selection receiving unit described above. The position adjustment instruction is an instruction to operate the movable part of the target sheet, and is an instruction related to an operation direction and an operation amount of the movable part.
In the position adjustment control means, a mechanism for operating the sheet is driven in order to realize the sheet position according to the contents of the position adjustment instruction received by the position adjustment instruction receiving means.

That is, the image guided to the user may include both an object that moves in accordance with the position adjustment of the target sheet and other objects around the object. Here, the other object is an object that is around the object and does not move with the movement of the object. For example, other seats adjacent to the target seat, luggage or the occupant's body in the vicinity of the target seat, and the like. By guiding the image including the object and the other object to the user, the user can adjust the position of the target sheet while grasping the positional relationship between the object and the other object.

  In the present invention, the guiding means may superimpose and display an icon for receiving the position adjustment instruction on the image. In this configuration, the position adjustment instruction accepting unit may accept a touch operation on the icon. That is, the reception of the position adjustment instruction may be realized by a touch panel display. According to this configuration, the user can instruct position adjustment of the sheet by a touch operation on the icon superimposed on the image, and the state of the sheet that operates in accordance with the instruction is displayed on the touch panel display. It can be confirmed with an image. Therefore, for example, compared with a configuration in which a position adjustment instruction is input by operating a button for position adjustment instruction provided on the outside of the display, the range of user's line-of-sight movement can be further reduced, and operability is improved. Can be improved.

  Further, in the present invention, the guide means derives a distance between the object and the other object based on the image information, and when the object and the other object approach within a predetermined distance, an alerting guidance May be performed. According to this configuration, when the user gives an instruction to adjust the position of the sheet, when the object and the other object are likely to approach and come into contact with each other, the user can be made aware of that. Regarding the derivation of the distance, for example, the position of the object and the position of the other object in the image are specified by pattern matching based on the image information, and the distance is derived. With regard to pattern matching, for example, an image captured by the camera in a state where there is no passenger or luggage in the vehicle is acquired in advance, and an image of an object that is fixedly present in the vehicle in the vehicle or in the vehicle is acquired in the image. A pattern is acquired in advance. If there is an image of a pattern that does not match those patterns in the image acquired by the image information acquisition means, it is determined that the image does not always exist in the vehicle (for example, an occupant, luggage, etc.), and the image of the pattern to be matched is It can be determined that the vehicle is always present in the vehicle (for example, a seat, a floor, an inner wall of the vehicle, etc.). As described above, the object existing in the image is identified, and the distance between the object that moves in accordance with the position adjustment of the target sheet and the other object is derived based on the number of pixels indicating the distance in the image. can do. In addition to the configuration using the distance derived from the number of pixels as the distance in the real space as described above, the distance between the objects is within the predetermined number of pixels without deriving the distance in the real space. You may employ | adopt the structure which implements alerting guidance. Note that various configurations can be adopted for the alerting guidance, such as a mode in which a display effect is applied so that the user's attention is directed to the part approaching the other object, a mode in which attention is given by voice, etc. It is.

  In the present invention, the information processing apparatus may further include distance information acquisition means for acquiring distance information indicating a distance between the object and the other object, and the guide means is configured to acquire the object and the other object based on the distance information. When an object approaches within a predetermined distance, alerting guidance may be performed. According to this configuration, when the user gives an instruction to adjust the position of the sheet, when the object and the other object are likely to approach and come into contact with each other, the user can be made aware of that. As a configuration for acquiring the distance information, for example, a configuration in which the distance information is acquired from a distance measuring sensor installed at a movable portion of the sheet, a position facing the movable portion, or the like can be employed. As a distance measuring sensor, for example, a radio wave such as a millimeter wave or an infrared ray is emitted and the radio wave reflected from the other object is received, and a distance between the object and the other object is determined from a propagation time or a frequency difference. A sensor to measure can be employed. In addition, regarding alerting guidance, various structures can be adopted as described above.

  Further, in the present invention, the position adjustment control means may have a function of acquiring a current position of the sheet within the movable range of the sheet, and the guide means is a current position of the sheet within the movable range. An indicator indicating that may be superimposed on the image. According to this configuration, the user can grasp the state of the state of the target sheet in the movable range of the target sheet with this indicator together with the image of the target sheet. This indicator and the above-described icon are superimposed on the target sheet or in the vicinity of the target sheet in the image. For example, when an occupant is seated on the target seat, it may be displayed at a position that does not overlap the image of the occupant, and may be displayed at a position that overlaps the target seat when the occupant is not seated. .

  Note that, as in the present invention, image information indicating an image including an object that operates in accordance with the position adjustment of the sheet is acquired, the image is guided to the user based on the image information, and the position of the user with respect to the sheet A method of accepting an adjustment instruction and operating the sheet in accordance with the position adjustment instruction can be applied as a program or a method for performing this process. In addition, the seat position adjustment device, the program, and the method as described above may be realized as a single device, or may be realized by using components shared with each part provided in the vehicle.

The control unit 20 is notified through the RR seat ECU 48a and the RL seat ECU 49a.

  The control unit 20 executes the sheet position adjustment program 21 to realize an effect of allowing the user to easily grasp the state of the sheet whose position is to be adjusted in cooperation with each of the above-described units, and the position of the user. Adjust the position according to the adjustment instructions. Therefore, the sheet position adjustment program 21 includes modules of a sheet selection reception unit 21a, an image information acquisition unit 21b, a guide unit 21c, a position adjustment instruction reception unit 21d, and a position adjustment control unit 21e.

  The seat selection receiving unit 21a is a module that causes the control unit 20 to realize a function of receiving selection of a sheet to be subjected to position adjustment among a plurality of seats existing in the vehicle. A sheet that is a candidate for position adjustment is presented, the user is allowed to select, and the selection is accepted. The image information acquisition unit 21b is a module that causes the control unit 20 to realize a function of acquiring image information indicating an image including an object that operates in accordance with the position adjustment of the selected sheet. After accepting the user's sheet selection, an image captured by a camera that includes the object corresponding to the sheet in the imaging range is acquired. The object that moves in accordance with the position adjustment of the sheet refers to the sheet itself (the entire sheet or a specific part of the sheet) that moves by the position adjustment, or an object that moves with the sheet. The object that moves together with the seat is an object that is supported by the seat or an object that is in contact with the seat, for example, the body of an occupant seated on the seat, luggage loaded on the seat, and leaning against the seat It is a thing that has been.

  The guide unit 21c is a module that causes the control unit 20 to realize a function of guiding an image including the object to a user who adjusts the sheet based on the acquired image information. The image may be an image including another object around the object that moves in accordance with the position adjustment of the sheet.

The position adjustment control unit 21e has a function 21e1 for acquiring the current position of the sheet within the movable range of the sheet.

(1-2) Sheet position adjustment processing:
In the present embodiment, the control unit 20 performs the sheet position adjustment process shown in FIG. 3 in order to realize the sheet position adjustment function in the above configuration. This processing is started when the seat position adjustment function is selected on the menu screen of the navigation system, for example, and the processing from step S105 to step S140 is repeated. First, the control unit 20 executes the process of the sheet selection receiving unit 21a to display a sheet selection screen for position adjustment on the touch panel display 40 (step S100), and waits for a user's touch operation. FIG. 4 shows an example of the screen displayed on the touch panel display 40 at this time, and shows that four images 460, 470, 480, and 490 corresponding to the seats in the passenger compartment are displayed on the screen. When the control unit 20 displays the screen on the touch panel display 40, the area where the images 460, 470, 480, and 490 are displayed is a reaction area that receives a touch operation for selecting a sheet corresponding to each image. To do.

  Note that the control unit 20 may store the sheet whose position has been adjusted last time, and display a screen in a state where the sheet is selected in step S100. That is, when the sheet whose position has been adjusted last time is the sheet RL49, a screen as shown in FIG. 5 may be displayed when the sheet position adjusting function is selected.

  Next, the control part 20 determines a user's touch operation (step S105). Specifically, the control unit 20 acquires the position of the area where the user performs a touch operation on the screen from the touch panel display 40, and the area is one of the reaction areas set corresponding to the current screen. It is determined whether or not this is true. For example, when the screen shown in FIG. 4 is displayed, it is determined whether it corresponds to one of the display areas of the images 460, 470, 480, and 490.

  Next, the control unit 20 determines which sheet is selected as an adjustment target by the processing of the sheet selection receiving unit 21a (step S110). If no sheet is selected, the process returns to step S105. If the touch operation detected in step S105 is a sheet selection touch operation, the selection of the sheet is accepted. For example, when the screen of FIG. 4 is displayed and the touch operation is performed on the display area of the image 490, the control unit 20 determines the touch area in step S105, and in step S110, the control unit 20 determines that the RL It is accepted that the sheet 49 has been selected.

  Next, the control unit 20 acquires the current position of the sheet within the movable range of the selected sheet by executing the process (sheet current position acquisition function) of the position adjustment control unit 21e (step S115). Specifically, the sheet position is acquired from the sheet position sensor of the target sheet. For example, it is acquired which position in the entire movable range the front / rear slide is in, and which angle is reclining.

  Next, the control unit 20 executes the processing of the image information acquisition unit 21b to determine whether there is a camera that includes the selected sheet in the shooting range, or whether an image can be acquired from the camera. Is determined (step S120). For example, when the RL sheet 49 is selected, it is determined whether or not a camera including the RL sheet 49 in the shooting range is provided in the vehicle, or if the camera is present, an image can be acquired from the camera. . If it is determined in step S120 that there is a camera that includes the selected sheet in the shooting range and an image can be acquired from the camera, the control unit 20 executes the process of the image information acquisition unit 21b. The image captured by the corresponding camera is acquired and displayed on the touch panel display 40 (step S125). In the present embodiment, when the RL sheet 49 is selected, the control unit 20 selects the camera 41 that includes the RL sheet 49 in the shooting range.

  Next, the control unit 20 executes the processing of the guide unit 21c, whereby an icon for receiving a position adjustment instruction in the image acquired in step S125, and an indicator that indicates the current position of the sheet within the movable range, Are superimposed and displayed (step S130). FIG. 5 shows an example of a screen displayed on the touch panel display 40 when the RL sheet 49 is selected. The indicator 404 indicates the movable range (graphics indicated by an ellipse) and the current position (graphics indicated by a circle) of the front and rear slide of the RL sheet 49, and the indicator 405 indicates the movable range and the current position of reclining. Yes. Therefore, the user can grasp the position of the target sheet in the movable range of the target sheet with this indicator. Icons 400 and 401 indicate switches for receiving an instruction (position adjustment instruction) for a forward / backward slide operation of the RL seat 49, and icons 402 and 403 are switches for receiving an instruction (position adjustment instruction) for a reclining operation. Is shown. That is, the area where the icons 400, 401, 402, and 403 are displayed is an area that overlaps the reaction area that receives the touch operation.

  Note that the above-described indicators and icons may be displayed in a superimposed manner at positions that do not overlap an occupant or luggage seated on the seat included in the image. For example, it is determined whether or not an occupant is seated on the target seat from the output of the seating sensor, and when the occupant is seated, the image is displayed at a position that does not overlap the occupant. If not, it may be displayed at a position overlapping the target sheet. Specifically, for example, the display position when the occupant is seated and the display position when the occupant is not seated are set in advance, and displayed according to the output of the seating sensor (whether or not seated). The areas may be switched.

  When it is determined that there is no camera that includes the sheet selected in step S120 in the shooting range or an image cannot be acquired from the camera, the control unit 20 displays a CG image imitating the sheet, an icon, and the like on the touch panel display 40. It is displayed (step S135). For example, as shown in FIG. 6, an image indicating a sheet, the above-described indicators 404 and 405, and icons 400, 401, 402, and 403 are displayed.

  Next, the control unit 20 receives the user's position adjustment instruction by executing the process of the position adjustment instruction receiving unit 21d, and executes the process of the position adjustment control unit 21e to load the sheet according to the position adjustment instruction. Operate (step S140). That is, when the touch operation detected in step S105 is a touch operation on the reaction area that receives a sheet position adjustment instruction, the control unit 20 receives the touch operation of the position adjustment instruction. For example, when the screen of FIG. 5 is displayed, if the touch operation detected in step S105 is a touch operation on the icon 401, the control unit 20 issues an instruction to slide the RL sheet 49 backward by one step. The RL seat ECU 49a drives the actuator 49d to slide the RL seat 49 backward by one step. If a touch operation corresponding to the position adjustment instruction is not detected in step S105, the position adjustment instruction is not accepted and the sheet operation instruction is not output in step S140.

  When the process of step S140 is completed, the process from step S105 described above is repeated again. By repeating the above processing, every time the user performs a touch operation on, for example, the icon 401 (see FIG. 5), the RL sheet 49 slides backward and a state of sliding backward is displayed on the touch panel display 40. The Each time the RL sheet 49 slides backward, the graphic indicating the current position indicated by the indicator 404 is also moved and displayed in the direction of the icon 401 with respect to the graphic indicating the movable range. As described above, in the present embodiment, when selection of a sheet to be subjected to position adjustment is received, guidance is provided by displaying an image of an object that operates in accordance with the position adjustment of the sheet on the touch panel display 40. Can easily grasp the state of the seat, the occupant seated on the seat, and the state of the luggage without moving the line of sight from the touch panel display 40. The user can adjust the position of the sheet while easily grasping the state of these objects.

  In addition, icons 400, 401, 402, and 403 and indicators 404 and 405 are superimposed on an image obtained by actually photographing the sheet, and the user can instruct the position adjustment of the sheet by touch operation on the icon, and The state of the sheet that operates in response to the instruction can be confirmed from the image displayed on the touch panel display. Therefore, for example, compared with a configuration in which a position adjustment instruction is provided by operating a button for position adjustment instruction provided outside the touch panel display 40, the range of the user's line of sight movement can be further reduced.

(2) Second embodiment:
FIG. 7 is a block diagram showing a configuration of the sheet position adjusting apparatus 10 according to the second embodiment. The difference from the first embodiment is that when the position adjustment is performed, a warning guide is provided when an object that moves along with the adjustment of the position of the sheet to be adjusted approaches another object within a predetermined distance. There is in point to do. In order to acquire the distance between the object and the other object, the present embodiment further includes cameras 43 and 44, a speaker 45, distance measuring sensors 46b and 47b, and a distance information acquisition unit 21f. Since other components are the same as those in the first embodiment, the same reference numerals are given, and descriptions thereof are omitted.

  As shown in FIG. 8, the camera 43 and the camera 44 are provided in the vicinity of the right and left C pillar ceilings, respectively. The camera 43 has the RR sheet 48 and the D sheet 46, and the camera 44 has the RL sheet 49 and the P sheet 47. Is mainly included in the shooting range. That is, the images photographed by the camera 43 and the camera 44 include both an object that operates in accordance with the position adjustment of the target sheet and other objects. Therefore, the image guided to the user also includes the object and the other object. Here, the other object is an object that is around the object and does not move with the movement of the object. For example, other seats adjacent to the target seat, luggage or the occupant's body in the vicinity of the target seat, and the like. By guiding the image including the object and the other object to the user, the user can adjust the position of the target sheet while grasping the positional relationship between the object and the other object.

  The distance measuring sensor is installed at a movable part of the sheet, a position facing the movable part, or the like. In the present embodiment, a distance measuring sensor 46b (for example, a distance measuring sensor using millimeter waves or infrared rays) is attached to the surface of the back of the D sheet 46 on the RR sheet 48 side, and the D sheet ECU 46a is a distance measuring sensor 46b. To RR sheet 48 is acquired. The distance measuring sensor 47b is attached to the RL sheet side surface of the back of the P seat ECU 47a, and the P sheet ECU 47a acquires distance information from the distance measuring sensor 47b to the RL sheet 49.

  The distance information acquisition unit 21f is a module that causes the control unit 20 to realize a function of acquiring distance information indicating a distance between an object that moves in accordance with the position adjustment of the adjustment target sheet and other objects. Specifically, the control unit 20 acquires information output from the distance measuring sensors 46b and 47b via the D seat ECU 46a and the P seat ECU 47a.

  FIG. 9 is a flowchart showing sheet position adjustment processing according to the second embodiment. Steps S100 to S140 are the same as the processing contents of the first embodiment, and thus description thereof is omitted. After finishing the process up to step S140, the control unit 20 executes the process of the guide unit 21c to obtain the distance between the object and the other object (step S145). Specifically, for example, the guide unit 21c derives the distance between the object and the other object based on the image information acquired by the image information acquisition unit 21b. More specifically, for example, the position of the object and the position of the other object in the image are specified by pattern matching based on the image information, and the distance is derived. With regard to pattern matching, for example, an image captured by the camera in a state where there is no passenger or luggage in the vehicle is acquired in advance, and an image of an object that is fixedly present in the vehicle in the vehicle or in the vehicle is acquired in the image. A pattern is acquired in advance. If there is an image of a pattern that does not match these patterns in the image acquired by the processing of the image information acquisition unit 21b, it is determined that the image does not always exist in the vehicle (for example, an occupant, luggage, etc.), and the pattern to be matched These images can be determined to be always present in the vehicle (for example, a seat, a floor, an inner wall of the vehicle, etc.). As described above, the control unit 20 identifies an object that exists in the image, and the distance between the object that moves in accordance with the position adjustment of the target sheet and the other object is a pixel that indicates the distance in the image. Derived based on the number. In addition to the configuration in which the distance between the objects is derived from the number of pixels as the distance in the real space as described above for determining the guidance execution, the number of pixels between the objects can be calculated without deriving the distance in the real space. If the number of pixels is within a predetermined number, a configuration for performing the alerting guidance may be adopted.
