Description

  The present invention relates to a posture adjustment device for a standing ride mobile body, a rider posture adjustment method, and a rider that adjusts the posture of the rider by adjusting the seating surface, backrest, or column of the standing ride mobile body. The present invention relates to an attitude adjustment program.

  The applicant is a standing-on-board moving body that can be installed in a standing position while balancing the weight of the seat and footrest in a well-balanced manner as a mobility support device that can be comfortably boarded even if seated comfortably for a long time. A proposal has already been filed. In order to maintain comfort when riding on a standing vehicle, the appropriate height and angle of the seating surface can be maintained even when the occupant has a different body shape. An adjustment function is necessary to maintain the angle. Furthermore, an adjustment means that can easily adjust the positions of the plurality of parts is required.

  Conventionally, in a vehicle seat or the like, means for easily adjusting a plurality of locations has been proposed. For example, an operation switch for a vehicle seat described in Patent Document 1 is shown in FIG. The vehicle is equipped with a slide mechanism that slides the seat back and forth, a reclining mechanism for adjusting the seating posture angle of the seat back, a lumbar support mechanism that adjusts the holding state of the seated person's waist, etc. Each operation switch 220 (220A, 220A, 220B, 220C, 220D) is installed on the side 212 of the seat 210. Among the operation switches 220, 220A is a seat slide switch, 220B is a reclining operation switch, 220C is a seat heater switch, and 220D is a lumbar support switch. In such a switch arrangement, since the operation switch 220 is arranged on the side of the seat, the passenger cannot directly check the switch 220 visually, and the mechanism operation is complicated.

  In order to solve this problem, Patent Document 1 incorporates a proximity sensor into the switch 220, and when a hand approaches the switch 220, a mechanism for detecting which of the four switches 220A to 220D is to be operated, and The four display units 230 corresponding to the four switches 220A to 220D, specifically the seat slide display unit 230A, and the reclining display unit 230B, are provided on the front side of the center console 232 that can be confirmed while the passenger is seated. The seat heater display unit 230C and the lumbar support display unit 230D are provided. By providing the display unit 230 with the result of the detected switch to the passenger, a seat operation switch is provided that allows the passenger to operate the appropriate mechanism without hesitation.

  FIG. 18 is a block diagram of the driving posture adjusting apparatus in Patent Document 2. This is also a patent relating to a vehicle seat adjustment means, which is based on the assumption that a single passenger repeatedly rides the floor position adjustment mechanism 230, the pedal position adjustment mechanism 240, the position control means 271, After the adjustment by the MAP correction unit 272, the adjustment result is stored in the storage unit 280. When the next adjustment is performed, the sheet is moved to the shape of the adjustment result stored in the storage unit 280. Later, manual fine adjustment is performed.

Thus, as shown in FIG. 3, the backrest 2a is inclined backward by about 10 degrees so that the head of the passenger 111 can be kept upright. Furthermore, when the occupant 111 sits on the seat 2b while leaning against the backrest 2a, the backrest 2a and the seat 2b have an angle of about 135 degrees between the center of gravity line from the spine of the occupant 111 to the pelvis and the femur. It is arranged to be. Thereby, the passenger 111 can get on the moving body 110 while maintaining a standing posture with a natural and low burden.

  A joystick 11 for driving the moving body 110 is installed at the tip 10a of the right handrail 10 of the handrail 10 installed on both sides of the seat 3. By tilting the lever 11a of the joystick 11 back and forth and right and left. The moving direction of the moving body 110 can be transmitted to the traveling drive system.

  FIG. 4 is a block diagram of the traveling drive system of the moving body 110. The output of the front / rear left / right signal of the joystick 11 is input to the operation controller 20 built in the movable body 4 to determine the motor voltage values of the left and right wheels. Thereafter, the drive motor controller 14 incorporated in the main body 4 converts the motor voltage value into a speed value, and the drive motors 15a and 15b rotate.

  In this mobile body 110, in order for the passenger 111 of various body types to maintain a standing posture with a natural and low burden without omission, the backrest 2a, the seat portion 2b, and further the seat 3 are adapted to the body shape. It is necessary to adjust the position of each supporting column 5. For example, FIG. 5A is a simulation diagram of the posture when the passenger 111 of a large system gets on the standing board moving body 110 of FIG. 1 in accordance with the passenger 111 of a small body type. The large passenger 111 cannot maintain the neutral position, that is, the optimum boarding position as it is. In other words, the angle formed by the center of gravity line from the spine to the pelvis and the femur is narrow, and the thigh does not contact the seat, but only a narrow area near the sciatus makes contact, so the posture is heavy. End up.

  Furthermore, since the backrest 2a is not long enough to touch the scapula, if the backrest 2a is inclined 10 degrees rearward, there is anxiety about leaning against the backrest 2a. In such a case, it is necessary to adjust at least the height of the column 5, the front and rear position of the seat 2b, and the vertical position of the backrest 2a according to the body shape (see FIG. 5B). Therefore, it is necessary to devise an arrangement so that the adjustment mechanism and means are not complicated as much as possible.

The nut 72 moves up and down along the ball screw 71 together with the column 5 so that the height of the seat 3 can be changed. Thus, the height of the column 5 can be adjusted up and down by the column height adjusting mechanism 32.

  Further, as shown in FIG. 1, an adjustment lever 12 is installed on the left side portion of the seat 3 as means for manually adjusting the adjustment portions of the backrest 2 a, the seat portion 2 b, and the column 5. . FIG. 9 shows the configuration of the adjustment lever 12. The adjustment lever 12 moves in two directions, up and down, and this movement is converted into an electric signal by the lever signal conversion unit 81, and the converted electric signal is input to the adjustment motor controller 93 via the communication cable 82. As will be described in detail later, when the passenger 111 adjusts the height or position of the backrest 2a, the seat 2b, or the support column 5, by moving the adjustment lever 12 up or down, the corresponding adjustment mechanism 30, 31 is adjusted. , 32 motors 52, 62, and 70 are driven forward and backward to manually adjust the height or position of the backrest 2 a, the seat 2 b, or the column 5 up and down or back and forth.

  For example, in the lever signal converter 81, when the adjustment lever 12 is tilted upward, a positive electrical signal is input to the adjustment motor controller 93, and when the adjustment lever 12 is tilted downward, A negative electric signal is input to the adjustment motor controller 93. In the adjustment motor controller 93, a backrest adjustment motor 52 is separately provided in accordance with an adjustment portion (any one of the backrest 2 a, the seat portion 2 b, and the column 5) determined by the personal computer (PC) 91. The seat adjustment motor 62 or the column adjustment motor 70 is selected, and if the adjustment part is the column 5 or the backrest 2a, the backrest adjustment motor 52 or the column adjustment is performed so as to move up and down. The motor 70 is controlled, and if it is the seat 2b, the seat adjustment motor 62 is controlled so as to operate forward and backward.

  Further, a push button 80 is disposed at the tip of the adjustment lever 12, and when the occupant 111 decides to start the posture adjustment and end the posture adjustment, each push button 80 is pressed, The personal computer 91 can be notified of the intention to start and end the adjustment with an electrical signal.

  Further, the left handrail 10 is provided with a speaker 13 for notifying the passenger 111 of the current adjustment target region and the start and end of the adjustment.

  In addition to the drive system motors 15a and 15b, the movable body main body 4 is provided with an adjustment motor power supply 94 for the position or height adjustment motors 52, 62 and 70, and controls them. It has a controller that can. Specifically, the drive wheel motor controller 14, drive power supply 21, left and right drive wheel motors 15 a and 15 b, sensor controller 90, personal computer 91, sensor power supply 92, and adjustment motor controller 93. And a motor power supply 94 for adjustment. The drive power supply 21 supplies necessary power to the drive wheel motor controller 14 and the left and right drive wheel motors 15a and 15b. The necessary power is supplied from the sensor power source 92 to the pressure sensor sheets 9a, 9b, 9c, 9d, the sensor controller 90, and the like. From the adjustment motor power supply 94, necessary power is supplied to the personal computer 91 and the like, the adjustment motor controller 93, the motors 52, 62, and 70.

  Next, details of the posture adjustment device 112 of the passenger 111 will be described.

  FIG. 10 shows the configuration of the posture adjustment device 112 of the moving body 110 related to posture adjustment, FIG. 11 is a functional block diagram in the personal computer 91 of the posture adjustment device 112, and FIG. 12 is a flowchart of posture adjustment processing.

  In FIG. 10, the sensor controller 90 receives the output value of the pressure element constituting each pressure sensor sheet 9a, 9b, 9c, 9d and the pressure element constituting each pressure sensor sheet 9a, 9b, 9c, 9d. The total value of the output values is calculated, and the pressure values of the sensor sheets 9a, 9b, 9c, 9d are output.

  Further, the PC 91 receives the adjustment start and adjustment end signals from the push buttons 80 and the output total value of the sensor controller 90 as inputs, and controls the seating status determination unit 100, the adjustment site determination unit 101 that determines the adjustment site information, and the control. The control unit 115 outputs necessary information (voice message) from the speaker 13 using the voice DB (database) 98 based on the processing result, and the control unit 115 drives the adjustment mechanism based on the processing result. The adjustment motor controller 93 that functions as an example of the control unit is operated. The control unit 115 includes a drive wheel motor controller 14 that controls the movement of the moving body 110 in the front-rear and left-right directions, a seating state determination unit 100, an adjustment site determination unit 101, a speaker 13, and an adjustment motor controller 93. As well as the overall movement of the moving object. Therefore, for example, during the posture adjustment, the operation of the drive wheel motor controller 14 can be controlled by the control unit 115 so that the moving body 110 does not move back and forth and right and left by mistake.

  The seating status determination unit 100 determines the seating status of the occupant 111 using outputs of pressure values of the posture sensors 9a, 9b, 9c, and 9d of the backrest 2a and the seat 2b.

  Using the determination result of the seating situation determination unit 100, the adjustment site determination unit 101 first allows the height of the column 5 to be adjusted, and after the adjustment of the column 5 is completed, allows the position of the seat 2b to be adjusted. When the adjustment of the portion 2b is completed, an adjustable portion is determined in order of the support column 5, the seat portion 2b, and the backrest 2a so that the position of the backrest 2a can be adjusted, and adjustment portion information that is the determination information is output.

  Based on the adjustment part information determined by the adjustment part determination unit 101, the adjustment motor controller 93 adjusts the part to be adjusted among the backrest height adjustment mechanism 30, the seat position adjustment mechanism 31, and the column height adjustment mechanism 32. The motors 52, 62, or 70 related to the related adjustment mechanism are controlled so that the adjustment can be performed by driving the adjustment lever 12 described later.

  13A to 13D are diagrams for explaining the posture adjustment processing. 13A to 13D, (a) is an explanatory diagram showing a boarding image when each part is adjusted for posture adjustment, and (b) is a pressure distribution image of a backrest during each part adjustment. Explanatory drawing, (c) is explanatory drawing showing the pressure distribution image of the seat surface in each part adjustment. Further, FIGS. 16A to 16C are flowcharts of manual adjustment of each part.

  The posture adjustment device 112 of the moving body 110 includes a backrest height adjustment mechanism 30, a seat position adjustment mechanism 31, a column height adjustment mechanism 32, a seating state determination unit 100, an adjustment part determination unit 101, and an adjustment mechanism. An adjustment motor controller 93 that functions as an example of a drive control unit is roughly configured.

  First, the passenger 111 determines whether or not the posture adjustment of the moving body 110 is necessary. When it is determined that it is necessary, for example, when the passenger 111 gets on the moving body 110 for the first time, when the passenger 111 gets on the moving body 110 and another passenger gets on the same moving body 110, or the same Even when the passenger 111 repeatedly rides on the same moving body 110, the passenger 111 himself / herself again determines that adjustment is necessary according to his / her body shape.

  When the passenger 111 determines that the posture adjustment is necessary, after the power source of the joystick 11, that is, the driving power source 21 is turned on, first, the push button 80 at the tip of the adjustment lever 12 is pressed to generate an adjustment start signal. Input to the personal computer 91 to start the process of step S50. Note that the power source of the joystick 11, that is, the driving power source 21 may always be on.

(Step S50)
When the push button 80 of the adjustment lever 12 is pressed, the moving body 110 returns the backrest 2a, the seat 2b, and the support column 5 to the appropriate initial positions in step S50 of FIG. Specifically, the backrest adjusting motor 52 is driven to operate the backrest height adjusting mechanism 30 so that the backrest 2a is positioned at the initial position (for example, the lowermost position). Also,
The seat adjustment motor 62 is driven to operate the seat position adjustment mechanism 31 to position the seat 2b at the initial position (for example, the rearmost position). Further, the column adjusting motor 70 is driven to operate the column height adjusting mechanism 32 so that the column 5 is positioned at the initial position (for example, the lowermost position). At this time, in order to ensure the safety of the passenger 111, it may be notified by voice from the speaker 13 that each part moves. At this time, for example, a voice message such as “Do not board because adjustment will start from now” from the voice DB 98 stored in the personal computer 91 may be used. In addition, the initial position at this time is preferably returned to a position where any type of passenger 111 can be seated. For example, the column 5 and the backrest 2a are the lowest position and the seat is the rearmost position. .

  The mobile body 110 may inform the passenger 111 by voice from the speaker 13 that the initial setting has been completed after moving each part to the initial position. For example, a voice message from the voice DB 98 “initial setting is complete.

(Step S51)
After the initial setting, the process proceeds to step S51, where the moving body 110 detects the total output value of the pressure sensor seats 9a, 9b, 9c, 9d of the backrest 2a and the seat 2b at regular intervals, for example, every 10 seconds. Calculated by the controller 90, and the calculation result is input to the personal computer 91. At the same time when the calculation result is input to the personal computer 91, in step S51, the personal computer 91 calculates the total seating surface pressure value calculated by the sensor controller 90. The passenger 111 is regarded as not on board, and the process is repeated at regular intervals. If the calculated total pressure on the seating surface is equal to or greater than a certain threshold value, it is considered that the passenger 111 is on the moving body 110, the process proceeds to step S52, and the seating state determination unit 100 determines the backrest of the moving body 110. Judgment is made on whether or not the 2a, the seat 2b, and the column 5 are suitable for the body shape and posture of the passenger 111.

  Before starting the determination, the speaker 13 may notify the passenger 111 that the determination of necessity of adjustment is started from the voice DB 98 included in the personal computer 91. From experience, it is assumed that the front sensor sheet 9d of the seat 2b is composed of, for example, 20 × 10 piezoelectric elements and the rear sensor sheet 9c is composed of, for example, 10 × 10 piezoelectric elements. Assuming that the pressure value represents the pressure value in 1 to 5 stages, the sum of the two sensor output values of the seat portion 2b is 150, indicating that the 1/4 surface of each sensor seat indicates the pressure value 2, It is appropriate to use the seating surface pressure threshold for determining the above.

  Before starting the determination, an example of a voice message to start the determination of necessity of adjustment from the voice DB 98 included in the personal computer 91 is, for example, “Check the suitability of posture from now on. Relax. You may output from the speaker 13 a voice message saying "Please sit down and wait for a while."

(Step S52)
Next, in step S52, the adjustment site determination unit 101 first determines whether or not posture adjustment is necessary for the riding posture of the passenger 111. In the determination, if all the necessary conditions for adaptation of each part described below are satisfied, posture adjustment is not necessary, and the process flow of posture adjustment is terminated. If none of them is satisfied, it is considered that posture adjustment is necessary, and the process proceeds to each step. Specifically, all the pressure output values (output total value) of the front part of the seating surface from the pressure sensor sheet 9d for the front part of the seating surface (that is, the total pressure value of the front part of the seating surface), the pressure sensor sheet 9c for the rear part of the seating surface All of the pressure output values (output total value) of the rear middle part of the seating surface from the left side, and all of the pressure output values (output total value) of the left and right upper parts of the backrest from the left and right backrest pressure sensor seats 9a and 9b correspond respectively. If the adjustment site determination unit 101 determines that each value is equal to or greater than a certain value (threshold value), posture adjustment is not started (step S53). If the adjustment site determination unit 101 determines that all the pressure output values of any one of the sites are less than a certain value (threshold value), the process proceeds to step S100 to start posture adjustment for that site. That is, if posture adjustment is necessary, the process proceeds to step S100 in order to adjust from the support column 5 first. If posture adjustment is not necessary for all parts (step S53), the posture adjustment processing ends.

  Empirically, as described above, for example, the seating surface front pressure sensor sheet 9d has 20 × 10 piezoelectric elements, the seating surface rear pressure sensor sheet 9c has 10 × 10 piezoelectric elements, and left and right piezoelectric elements. The backrest pressure sensor sheets 9a and 9b are each composed of 7 × 10 piezoelectric elements on one side. Assuming that each piezoelectric element expresses a pressure value in 1 to 5 stages, a value that a half surface of each sensor sheet indicates a pressure value 2, specifically, a pressure sensor sheet for a seat front portion It is appropriate that 9d is 200, the seat pressure sensor sheet 9c for the rear portion of the seat is 100, and the pressure sensor sheets 9a and 9b for the left and right backrests are each 70 as the seating threshold value of each part considered to have been properly adjusted. .

(Step S100)
First, in step S100, the seating situation determination unit 100 starts analyzing the seating situation. First, the total pressure value of the front of the seat surface (the front half of the seat surface 2b in the traveling direction) output by the sensor controller 90 is compared with a predetermined seat surface front seating threshold value. If the seating status determination unit 100 determines that the total pressure value in front of the seating surface is equal to or greater than the seating threshold value, the process proceeds to step S101. When the seating state determination unit 100 determines that the total pressure value in front of the seating surface is less than the seating threshold value, the process proceeds to step S110.

(Step S110)
In step S110, the seating state determination unit 100 determines that the seat surface 2b is too low and the feet of the occupant 111 are sitting on the feet (for example, in the case of images (a) and (c) in FIG. 13A). Then, the control unit 115 outputs a voice message of the voice DB 98 intended to prompt the passenger 111 to adjust the column from the speaker 13. As an example of the voice message in the voice DB 98, “the height adjustment of the column is started” may be used. Then, the process proceeds to step S111.

  (Step S111) Simultaneously with the voice notification, in Step S111, the adjustment part flag is set in the column 5 based on the adjustment part information from the adjustment part determination part 101 based on the determination result in the sitting state determination part 100, and the adjustment is performed. The adjustment part information is input to the motor controller 93 for use. The adjustment motor controller 93 is set so that the signal from the adjustment lever 12 is input to the column adjustment motor 70 so that the signal of the lever position from the adjustment lever 12 is reflected in the vertical direction of the column height. Then, the process proceeds to step S112.

(Step S112)
In step S112, the adjustment of the column 5 is started. Specifically, the processing of step S140 to step S144 in FIG. 16A is performed.

(Steps S140 and S141)
First, before the passenger 111 starts manual adjustment, in steps S140 and S141, the seating state determination unit 100 determines that the total pressure value in front of the seating surface is a constant value (for example, a seating threshold value of the seating front portion described later). If it is equal to or less than a certain value, the control unit 115 of the PC 91 performs automatic control in the direction of increasing the height of the column 5. This control is realized by operating the column adjustment motor 70 via the adjustment motor controller 93. In this case, for the safety of the passenger 111, the control unit 115 causes the voice message of the voice DB 98 to be automatically adjusted to an appropriate height before adjustment by the customer. 13 is preferably notified so that the passenger 111 does not move. When the total pressure value in front of the seat surface becomes equal to or greater than the predetermined value (adjustment preparation threshold value smaller than the seating threshold value), the process proceeds to step S142.

(Step S142)
In step S142, the automatic adjustment is terminated, and a switching signal is sent from the control unit 115 so that the signal when the adjustment lever 12 is manually moved up or down is reflected in the adjustment motor controller 93 instead of the automatic adjustment. Input to the adjustment motor controller 93 to switch the control in the adjustment motor controller 93. Thereafter, the process proceeds to step S143.

(Step S143)
In step S143, manual adjustment by the passenger 111 is started. In that case, the control unit 115 may notify the passenger 111 of the timing of the start of manual adjustment from the speaker 13 with a voice message of the voice DB 98, for example, “Please make fine adjustments.”

  In the manual adjustment, the height of the support column 5 is adjusted by tilting the adjustment lever 12 upward or downward. For example, when the adjustment lever 12 is tilted upward, the column adjustment motor 70 is driven to raise the column 5, and the thigh of the occupant 111 contacts the seat surface PS3 of the seat 2b and sits down. The total pressure value in front of the surface increases. On the other hand, when the adjustment lever 12 is tilted downward, the support adjusting motor 70 is reversely driven to lower the support 5 and the seat surface PS3 of the seat 2b is separated from the thigh and the seat front is moved forward. The total pressure value becomes smaller. At this time, the seating state determination unit 100 always compares the total pressure value in front of the seat surface with a predetermined seating threshold value in front of the seat surface. When the seating state determination unit 100 determines that the total pressure value in front of the seat is greater than the seating threshold in front of the seat, the control unit 115 notifies the passenger 111 that the adjustment target has been achieved. A target achievement notification sound determined from the speaker 13 is transmitted. When the seating state determination unit 100 determines that the total pressure value in front of the seating surface is equal to or less than the seating threshold value in front of the seating surface, the determination process associated with manual adjustment is continued.

(Step S144)
The passenger 111 manually adjusts the strut 5 to an optimum height within the range where the notification sound is transmitted while checking the target achievement notification sound with his / her ear, and then adjusts the tip of the adjustment lever 12. By pressing the button 80, the control unit 115 is notified that the adjustment has been completed (step S144). At this stage, an explanatory diagram representing the boarding image and an explanatory diagram representing the sensor output image of the backrest and the seat are (a), (b), and (c) in FIG. 13B, respectively. Next, the process proceeds to step 101.

(Step S101)
If it is determined in step S100 that height adjustment is not necessary, and if the column adjustment is completed in step S112, then in step S101, the seat 2b is adjusted.

  First, in step S101, the seating situation determination unit 100 starts analyzing the seating situation. First, the total pressure value of the rear of the seat surface (the rear half opposite to the traveling direction of the seat surface 2b) output by the sensor controller 90 is compared with a predetermined seat rear seating threshold value. When the seating state determination unit 100 determines that the total pressure value behind the seating surface is equal to or greater than the seating threshold, the process proceeds to step S102. If the seating status determination unit 100 determines that the total pressure value behind the seating surface is less than the seating threshold, the process proceeds to step S120.

(Step S120)
In step S120, the seating state determining unit 100 determines whether the seat is easily slipped off from the seating portion 2b (for example, in the case of the images (a) and (c) in FIG. 13B), and the control unit 115 determines the seating from the speaker 13. The voice message of the voice DB 98 intended to prompt the passenger 111 to make a section adjustment is output. As an example of the voice message of the voice DB 98, “Please adjust the seat.” Or “Is the seat easy to slide? Please adjust.” Then, the process proceeds to step S121.

  (Step S121) Simultaneously with the voice notification, in Step S121, the adjustment part flag is set to set the adjustment part to the seat part 2b based on the adjustment part information from the adjustment part determination part 101 based on the determination result in the seating state determination part 100. Is set in the seat 2b, and the adjustment part information is input to the adjustment motor controller 93. The adjustment motor controller 93 is set so that the lever position signal from the adjustment lever 12 is reflected in the front-rear direction of the seat surface position. Thereafter, the process proceeds to step S122.

(Step S122)
After the setting, in step S122, the adjustment of the seat 2b is started. Specifically, the processing of step S150 to step S154 in FIG. 16B is performed.

(Steps S150 and S151)
First, before the passenger 111 starts manual adjustment, in steps S150 and S151, the seating state determination unit 100 determines that the total pressure value behind the seating surface is a constant value (for example, the seating threshold value behind the seating surface described later). If it is less than a certain value, it is automatically controlled from the control unit 115 of the PC 91 in the direction of increasing the height of the seat 2b. This control is realized by operating the seat adjustment motor 62 via the adjustment motor controller 93. At this time, for the safety of the passenger 111, the control unit 115 sends a voice message of the voice DB 98 saying “Adjust automatically to an appropriate position before making adjustments by the customer. It is preferable to notify that the passenger 111 does not move. When the total pressure value of the rear part of the seat surface becomes equal to or higher than the predetermined value, the process proceeds to step S152.

(Step S152)
In step S152, the automatic adjustment is terminated, and a switching signal is sent from the control unit 115 so that the signal when the adjustment lever 12 is manually moved up or down is reflected in the adjustment motor controller 93 instead of the automatic adjustment. Input to the adjustment motor controller 93 to switch the control in the adjustment motor controller 93. Thereafter, the process proceeds to step S153.

(Step S153)
In step S153, manual adjustment by the passenger 111 is started. In that case, the control unit 115 may notify the passenger 111 of the timing of the start of manual adjustment from the speaker 13 with a voice message of the voice DB 98, for example, “Please make fine adjustments.”

  In manual adjustment, the adjustment lever 12 is tilted up or down to adjust the position of the seat portion 2b in the front-rear direction. For example, when the adjustment lever 12 is tilted upward, the seat adjustment motor 62 is driven to move the seat 2b backward, and the pressure of the buttocks near the sciatic bone of the passenger 111 acting on the seat 2b. Increases and the total pressure value behind the seating surface increases. On the other hand, when the adjustment lever 12 is tilted downward, the seat adjustment motor 62 is driven to move the seat 2b forward, and the buttock near the sciatic bone of the occupant 111 acting on the seat 2b. As the pressure decreases, the total pressure value behind the seating surface decreases. At this time, the seating status determination unit 100 always compares the total pressure value behind the seating surface with a predetermined seating threshold behind the seating surface. When the seating state determination unit 100 determines that the total pressure value behind the seating surface is larger than the seating threshold behind the seating surface, the control unit 115 informs the passenger 111 that the adjustment target has been achieved. A target achievement notification sound determined from the speaker 13 is transmitted. When the seating state determination unit 100 determines that the total pressure value behind the seating surface is equal to or less than the seating threshold behind the seating surface, the determination process accompanying the manual adjustment is continued.

(Step S154)
The passenger 111 manually adjusts and adjusts the seat portion 2b to a position where the user feels most comfortable within the range in which the notification sound is transmitted while confirming the target achievement notification sound with his / her ear, and then adjusts the lever 12 for adjustment. By pressing the previous push button 80, the control unit 115 is informed that the adjustment has been completed (step S154). At this stage, the explanatory diagram representing the boarding image and the explanatory diagram representing the sensor output image of the backrest and the seat are (a), (b), and (c) in FIG. 13C. Next, the process proceeds to step 102.

(Step S102)
When it is determined in step S101 that the position adjustment of the seat 2b is not necessary, and when the adjustment of the seat 2b is completed in step S122, the backrest 2a is adjusted in step S102.

  First, in step S102, the sitting situation determination unit 100 starts analyzing the sitting situation. First, the total pressure value of the upper left part of the backrest (left half of the upper half of the backrest 2a) and the upper right part (left side of the upper half of the backrest 2a) output by the sensor controller 90, and each predetermined upper left and right parts The back seating threshold value is compared. When either of the total pressure values is equal to or greater than the seating threshold value, the seating status determination unit 100 determines that the posture summoning process is terminated. If either of the total pressure values is less than the seating threshold value, the seating status determination unit 100 determines that the process proceeds to step S130.

(Step S130)
In step S130, the seat back state 2a is too low and there is a danger of falling back (for example, the images (a) and (b) of FIG. 13C). From the speaker 13, the voice message of the voice DB 98 intended to prompt the passenger 111 to adjust the backrest is output. As an example of the voice message of the voice DB 98, “Please adjust the backrest.” Or “Is the backrest too low? Please adjust.” Then, the process proceeds to step S131.

(Step S131)
Simultaneously with the voice notification, in step S131, the adjustment part is set to the backrest 2a based on the adjustment part information from the adjustment part determination part 101 based on the determination result in the seating state determination part 100, and in the case of the column 5 and the seat part 2b Similarly to the above, the adjustment part flag is set to the backrest 2a, and the adjustment part information is input to the adjustment motor controller 93. The adjustment motor controller 93 is set so that the lever position signal from the adjustment lever 12 is reflected in the vertical height of the backrest 2a. Thereafter, the process proceeds to step S132.

(Step S132)
After the setting, in step S132, the adjustment of the backrest 2a starts. Specifically, the processing of step S160 to step S164 in FIG. 16C is performed.

(Steps S160 and S161)
First, before the passenger 111 starts manual adjustment, in steps S160 and S161, the seating state determination unit 100 determines that the total pressure values of the upper left back and upper right are constant values (for example, the seating threshold of the backrest). If it is equal to or less than a certain value, it is automatically controlled by the control unit 115 of the PC 91 in the direction of increasing the height of the backrest 2a. This control is realized by operating the backrest adjustment motor 52 via the adjustment motor controller 93. In this case, for the safety of the passenger 111, the control unit 115 causes the voice message of the voice DB 98 to be automatically adjusted to an appropriate height before adjustment by the customer. 13 is preferably notified so that the passenger 111 does not move. When the total pressure value of the upper left back and the upper right of the backrest is equal to or higher than the predetermined value, the process proceeds to step S162.

(Step S162)
In step S162, the automatic adjustment is terminated, and a switching signal is sent from the control unit 115 so that the signal when the adjustment lever 12 is manually moved up or down is reflected in the adjustment motor controller 93 instead of the automatic adjustment. Input to the adjustment motor controller 93 to switch the control in the adjustment motor controller 93. Thereafter, the process proceeds to step S163.

(Step S163)
In step S163, manual adjustment by the passenger 111 is started. In that case, the control unit 115 may notify the passenger 111 of the timing of the start of manual adjustment from the speaker 13 with a voice message of the voice DB 98, for example, “Please make fine adjustments.”

  In the manual adjustment, the height of the backrest 2a in the vertical direction is adjusted by tilting the adjustment lever 12 upward or downward. At this time, for example, when the adjustment lever 12 is tilted upward, the backrest adjustment motor 52 is driven to move the backrest 2a upward, and the pressure on the back of the passenger 111 acting on the backrest 2a is increased. Thus, the total pressure value of each of the left and right upper portions of the backrest increases. On the contrary, when the adjustment lever 12 is tilted downward, the backrest adjustment motor 52 is driven to move the backrest 2a downward, and the pressure on the back of the passenger 111 acting on the backrest 2a is reduced. The total pressure value of each of the upper and lower backrests becomes smaller. At this time, the seating state determination unit 100 always compares the total pressure value of the left and right backrests with a predetermined seating threshold of the backrest. When the seating state determination unit 100 determines that the total pressure value of each of the left and right upper portions of the backrest is larger than the seating threshold value for the backrest, the control unit 115 notifies the passenger 111 that the adjustment target has been achieved. The target achievement notification sound determined by the speaker 13 is transmitted. When the seating state determination unit 100 determines that the total pressure values of the upper and lower backrests are both lower than the seating threshold for the backrest, the determination process accompanying the manual adjustment is continued as it is.

(Step S164)
The passenger 111 manually adjusts the backrest 2a to the height at which it feels most comfortable within the range in which the notification sound is transmitted while confirming the target achievement notification sound with the ear. By pressing the previous push button 80, the control unit 115 is informed that the adjustment has been completed (step S164). At this stage, the explanatory diagram representing the boarding image and the explanatory diagram representing the sensor output image of the backrest and the seat are (a), (b), and (c) in FIG. 13D. This completes the posture adjustment process.

  That is, if it is determined in step S102 that the vertical adjustment of the backrest is not necessary, and the adjustment of the backrest 2a is completed in step S132, the adjustment processing for all parts is completed.

  When the posture adjustment is finished, the control unit 115 notifies the passenger 111 that the adjustment is finished. For example, a voice message of the voice DB 98 “Adjustment is completed” may be output from the speaker 13.

  In this embodiment, the posture is adjusted in the order of the support 5, the seat 2 b, and the backrest 2 a, but this order is appropriate so that the adjustment work is not complicated without repeating the adjustment of each part many times. I think there is.

  For example, FIG. 14B shows an explanatory diagram showing a riding posture image after the seat adjustment when the seat adjustment is performed before the column adjustment. If the seat 2b is adjusted forward while the column 5 is low, the occupant 111 cannot support his / her weight with his / her legs on the backrest 2a. The relative weight moves to the front of the seat. Therefore, depending on the situation, the rear portion of the seat surface where the buttocks in the vicinity of the scapula of the occupant 111 come into contact (the black line portion 200 of the seat portion 2b in FIG. 14B) regardless of the position in the front-rear direction. ) Does not apply pressure above a certain value, and even if the seat 2b cannot be determined at an appropriate position, or even if pressure is applied to the rear center of the seat and the seat position is set, At the stage of adjusting the height (see FIG. 14C), the pressure value at the rear center part of the seat surface (for the black line 201 of the seat part in FIG. 14C) changes as the waist angle changes. After adjusting the column, it is necessary to adjust the position of the seat 2b again.

  FIG. 15A is an explanatory diagram showing a riding posture image after the backrest adjustment when the backrest adjustment is performed before the seat portion adjustment. Before the seat adjustment, there is no guarantee that the weight is supported by the sciatic bone or the buttocks (that is, at least the buttocks near the sciatic bone) so that it does not slip from the seat 2b. May be supported. In such a case, the hip angle becomes obtuse than 135 degrees, and if the backrest 2a is adjusted in this state, the scapula comes into contact with the backrest 2a in a state lower than the appropriate height. Therefore, after adjusting the seat 2b, the waist angle becomes 135 degrees (see FIG. 15B), and it is necessary to adjust the backrest again (see FIG. 15C).

  It is considered appropriate to adjust each part in the order of the column 5, the seat 2b, and the backrest 2a.

  According to the embodiment, the seat 3 is configured by the backrest 2a and the seat portion 2b, so that the passenger 111 can sit on the seat surface PS3 and keep the head upright in a standing posture with low load. In the moving body 110 in which the angle between the backrest surface PS1 and the seating surface PS3 is taken into consideration, it is possible to realize the standing riding moving body 110 that can ride in a comfortable posture regardless of the body shape of the passenger 111. For this purpose, the seating status of the passenger 111 should be automatically determined by the seating status determination unit 100 based on information from the posture sensors 9a, 9b, 9c, 9d, and uniquely adjusted according to the determined seating status. The site can be determined by the adjustment site determination unit 101. By comprising in this way, the passenger | crew 111 does not use the some adjustment switch corresponding to the some site | part used as an adjustment target, but the passenger | crew 111 is a site | part by following the order of the adjustment site | part automatically determined by the attitude | position adjustment apparatus. Thus, it is possible to appropriately adjust a plurality of parts sequentially with one switch (adjustment lever 12) without wondering about the state or the adjustment order. That is, even if it is necessary to adjust a plurality of parts to match the body shape of the passenger 111, one switch (adjusting lever 12) can be used without wondering which part the passenger 111 should adjust in which order. Thus, it is possible to sequentially adjust a plurality of parts, and it is possible to provide a posture adjusting device for the moving body 110 that eliminates the complexity of the conventional adjustment.

  In the embodiment, the posture sensors 9a and 9b are arranged on a part of the backrest surface PS1, but they may be arranged on the entire surface. Similarly, the attitude sensor 9c is also arranged on a part of the rear part of the seating surface PS3, but may be arranged on the entire rear part. Although the posture sensor 9d is also disposed on the entire front surface of the seating surface PS3, it may be disposed on a part of the front portion (portion where the thigh is in contact).

  Note that the present invention is not limited to a standing-on board moving body, but can also be applied to a normal sitting-on board moving body.

  In addition, it can be made to show the effect which each has by combining arbitrary embodiment or modification of the said various embodiment or modification suitably.

  The standing ride moving body, the standing ride moving body, the occupant posture adjustment method, and the occupant posture adjustment program according to the present invention are adapted to the occupant's body shape or posture. This is useful when there is a need to adjust a plurality of points such as the height or position of the seat or backrest or column. In addition, it is also useful as an adaptation method according to the body shape of a personal mobile body, a mobile support robot, or a health support device.
