JP-A-7-96786

  In the driving posture adjusting device described in Patent Document 1, the driving posture is adjusted by adjusting the relative positions of the seat, the accelerator pedal, and the brake pedal. There is no disclosure of position adjustment. In adjusting the position of each pedal, it is often the case that each pedal is moved while keeping the same amount of movement, that is, a step difference between the pedals.

  By the way, in the adjustment of the driving posture, it is desirable that the pedal arrangement and the setting angle such as the step and the interval between the accelerator pedal and the brake pedal (and the clutch pedal) are ergonomically appropriate. When the pedal is moved while maintaining the same amount of movement as described above, a large sized occupant sits on the seat and each pedal is operated, and a small sized occupant sits on the seat and each pedal is There is a disadvantage that the operability of each pedal and the feeling of foot placement on each pedal differ depending on the operation.

  That is, regardless of the adjustment of the position of the pedal, if the mutual arrangement of the pedals such as the step and the interval between the pedals is kept constant, the ratio of the operation amount such as the stepping operation to the foot length in the occupant of a large physique, The ratio of the amount of operation such as stepping movement to the foot length in the occupant of a small physique is different, so the operability to operate the pedal and the feeling of placement on the pedal change depending on the physique of the occupant sitting on the seat, As a result, it is difficult to adjust the pedal position to an appropriate pedal for any occupant, and there is room for improvement in this regard.

  In view of the above circumstances, the present invention adjusts the relative position between the pedals with respect to the position of one pedal in adjusting the driving posture, regardless of the physique of the occupant sitting on the seat. It is an object of the present invention to provide a driving posture adjusting device capable of keeping operability and a feeling of placing on a pedal constant.

  A driving posture adjusting apparatus for an automobile according to the present invention includes a seat on which an occupant is seated, a reference pedal disposed in front of the seat and operated to rotate by the occupant's feet, and front and rear with respect to the reference pedal. A stepped body that is arranged side by side with a predetermined step in the direction and that comes into contact with the occupant's foot, and adjusts the position of the seat, the reference pedal, and the stepped body to change the driving posture of the occupant In the vehicle driving posture adjusting apparatus to be adjusted, reference position adjusting means for adjusting the position of the reference pedal along the longitudinal direction of the vehicle body, and the stepped body in conjunction with the position adjustment of the reference pedal by the reference position adjusting means A position adjustment means for adjusting the position of the vehicle body along the front-rear direction of the vehicle body and reducing the step difference with respect to the reference pedal as the reference pedal moves in a direction closer to the seat. Is characterized in that the obtaining (claim 1).

  In this case, the stepped body is disposed with a predetermined interval in the vehicle width direction with respect to the reference pedal, and at least one of the stepped body position adjusting means and the reference position adjusting means is configured such that the reference pedal is seated. It is preferable that the interval is reduced as it moves in the direction closer to the first position.

  According to another aspect of the present invention, there is provided a driving posture adjusting device for an automobile, a seat on which an occupant is seated, a reference pedal disposed in front of the seat and rotated by the occupant's feet, and the reference pedal. A stepped body that is arranged side by side with a predetermined interval in the vehicle width direction and that contacts the foot of the occupant, and adjusts the position of the seat, the reference pedal, and the pedestal, thereby driving the occupant In a vehicle driving posture adjusting device for adjusting the posture, a reference position adjusting means for adjusting the position of the reference pedal along the longitudinal direction of the vehicle body, and the stepping in conjunction with the position adjustment of the reference pedal by the reference position adjusting means Adjusting the body position along the longitudinal direction of the vehicle body, and stepping body position adjusting means for reducing the distance to the reference pedal as the reference pedal moves in a direction closer to the seat. Is characterized in that the obtaining (claim 3).

  According to these inventions, the position of the stepped body is adjusted in conjunction with the position adjustment of the reference pedal that is rotated by the occupant's foot by the reference position adjusting means, and the reference pedal approaches the seat. Since it includes a step body position adjustment means that reduces the step and step distance of the step body relative to the reference pedal as it moves in the direction, one pedal among various pedals (accelerator pedal, brake pedal, etc.) By linking the pedal body position adjusting means to this reference pedal, the position of the pedal body such as other pedals and footrests other than the reference pedal can be adjusted efficiently. As the reference pedal moves in the direction closer to the seat, the stepped portion and the distance between the reference pedal and the reference pedal are reduced, that is, the seat is seated on the seat. In view of the fact that the reference pedal is moved closer to the seat as the occupant's physique becomes smaller, the level difference and spacing of the stepped body with respect to the reference pedal is also reduced. The height and the step of the stepping body with respect to the reference pedal can be adjusted according to the length and the length of the reference pedal, so that the height and the height are set according to the physique of each occupant. Therefore, the operability and placement feeling of the reference pedal and the stepped body by the passenger can be kept constant.

  In addition, if the pedal body is a predetermined pedal or footrest that is juxtaposed with the reference pedal, the feeling of placement of the occupant's foot placed on the pedal can be kept constant. If the pedal is a predetermined pedal or footrest that can be switched from the reference pedal by the occupant's foot, the operability when the pedal is switched can be kept constant. If set, the certainty to the operation of the reference pedal or the predetermined pedal can be improved.

  In these inventions, the apparatus further comprises seat position adjusting means for supporting the seat so that the position of the seat can be adjusted along the longitudinal direction of the vehicle body. The seat position adjusting means and the reference position adjusting means include the reference pedal, The reference position adjusting means is configured to turn the reference pedal to the seat in accordance with the forward movement of the seat by the seat position adjusting means. The reference pedal is moved to a position where a line of sight toward a predetermined vehicle body portion of a standard body occupant seated in a normal posture in cooperation with the seat is substantially constant while being moved in the approaching direction. (Claim 4).

  That is, when the seat is moved forward by the seat position adjusting means, it is assumed that the occupant seated on the seat has a small physique. In such a case, the reference pedal by the reference position adjusting means is also moved closer to the seat. By moving it, it is possible to efficiently adjust the driving posture according to the physique of the occupant. Moreover, the seat position adjusting means and the reference position adjusting means are configured to rotate the reference pedal and the stepping body about a predetermined rotation center axis extending in the vehicle width direction, respectively. The reference pedal is moved to a position where the line of sight toward a predetermined vehicle body portion of a standard occupant seated in a normal posture in cooperation with the seat moves to a position where the line of sight is substantially constant. The position of the seat and the reference pedal can be adjusted while keeping the line of sight with respect to the front edge of the vehicle constant, and the driving posture can be adjusted regardless of the physique of the occupant seated on the seat.

  In the driving attitude adjusting device for an automobile according to claim 1 or 2, the step body position adjustment means supports the step body on the seat side with respect to the reference pedal with respect to a position in the front-rear direction. (Claim 5).

  That is, in order to reduce the level difference between the step body and the reference pedal by the step body position adjusting means, the relative distance between the step body and the reference pedal may be shortened. The relative distance between the two can be shortened simply by reducing the amount of movement of the stepper linked to the base, that is, the relative distance between the two can be shortened by effectively utilizing the position adjustment of the reference pedal by the reference position adjusting means. Thus, the step can be reduced easily and quickly.

  In this case, the reference position adjusting unit and the stepped body position adjusting unit adjust the positions of the reference pedal and the stepped body by rotating the reference pedal and the stepped body about different rotation center axes extending in the vehicle width direction. It is preferable to be configured as (Claim 6).

  With this configuration, the center axis of each rotation adjustment of the reference pedal and the stepping body can be set relatively freely. If each rotation adjustment center axis is set to an appropriate position, the change of each pedal ratio, etc. Can be suppressed. That is, when a different rotation axis, for example, a stepped body is configured as the predetermined pedal, the reference pedal is adjusted to rotate about the rotation operation center axis, and the predetermined pedal is centered about the rotation operation center axis. If the configuration is such that the pedal is pivotally adjusted, the pedal ratio can be kept constant, and the operation amount of the pedal can be kept constant regardless of the front-rear position of each pedal.

  Further, in place of the above configuration, the step body is a predetermined pedal provided in parallel with the reference pedal, and the reference position adjusting means and the step body position adjusting means are configured to connect the reference pedal and the predetermined pedal. It is configured to rotate around different operation center axes extending in the width direction and is configured to adjust its position by rotating around the same rotation center axis extending in the vehicle width direction. Preferred (claim 7).

  If comprised in this way, since it is comprised so that the operation center axis | shaft of a reference | standard pedal and a predetermined pedal may be rotated around a different axis | shaft, interference with another vehicle-mounted member is ensured, ensuring operation reliability. By avoiding the operation, the operation center axes can be arranged relatively easily. In addition, since it rotates about the same rotation center axis (rotation adjustment center axis), the driving posture of the occupant can be rotated about this rotation adjustment center axis, and the feeling of placement on each pedal is constant. Can be kept in. Here, when the pedals are rotated around the same rotation adjustment center axis as described above, especially when this rotation adjustment center axis is set as the operation center axis of the reference pedal, the pedal ratio of the predetermined pedal changes relatively greatly. There are things to do. However, since this configuration is based on the configuration of the fifth aspect, that is, the step body position adjusting means supports the step body on the seat side with respect to the reference pedal in the front-rear direction position. Therefore, the amount of movement at the time of adjusting the position of the predetermined pedal can be reduced, and this change in pedal ratio can be suppressed. That is, a change in the pedal ratio can be suppressed as much as possible while ensuring operability according to the physique of the occupant seated on the seat.

  In this case, the reference pedal is preferably an accelerator pedal, and the predetermined pedal is preferably a brake pedal having an operation center axis disposed above the operation center axis of the reference pedal and having a long arm. (Claim 8).

  If comprised in this way, this accelerator pedal will suppress the fatigue | exhaustion of the passenger | crew who adjusts a driving posture by this apparatus as much as possible by performing each pedal operation on the basis of the accelerator pedal with comparatively long operation time, and this accelerator pedal. Therefore, it is possible to provide a brake pedal having a good pedal changeability and little change in pedal ratio.

  In the driving posture adjusting device for an automobile according to claim 1 or 2, the pedal body includes a predetermined pedal operated by the occupant's foot and a position where the pedal can be switched with respect to the predetermined pedal. The footrest position adjusting means is preferably configured to keep the relative position between the predetermined pedal and the footrest constant. 9).

  With this configuration, the relative position between the footrest that does not need to be operated by the occupant's foot and a predetermined pedal (for example, a clutch pedal) is kept constant regardless of the position of the reference pedal, It is possible to simplify the apparatus while keeping the changeability with the footrest as good as possible.

  Further, in the driving posture adjustment apparatus for an automobile according to claim 1 or 2, the footrest includes a footrest on which the foot of the occupant is placed, and the footrest is positioned with respect to the reference pedal. Mounted on an adjustable movable floor, the stepped body position adjusting means corresponding to the footrest is configured as a floor position adjusting means for adjusting the position of the movable floor, and the floor position adjusting means is configured such that the reference pedal is close to the seat. It is preferable that the movable floor is configured to move in a direction close to the reference pedal as it moves in the direction of movement.

  With this configuration, since the movable floor is provided, the placement stability of the foot of the occupant is improved by following the movable floor regardless of the position adjustment of each reference pedal and the stepping body, and the movable floor By providing the footrest on the floor, it is possible to further improve the foot placement while simplifying the apparatus.

  According to the vehicle driving posture adjusting apparatus of the present invention, one pedal among various pedals is used as a reference, and the pedal position adjusting means is interlocked with the reference pedal, and a pedal such as a predetermined pedal or a footrest other than the reference pedal is used. By adjusting the position of the mounting body, the position of the stepping body can be adjusted efficiently, and as the reference pedal moves in the direction closer to the seat by the stepping body position adjusting means, that is, the seat As the physique of the occupant seated in the seat becomes smaller, the level difference and spacing of the stepped body with respect to the reference pedal will be reduced, so the occupant's foot size and length of the occupant seated on the seat It is possible to adjust the step and the distance of the stepped body with respect to the pedal, so that it is set to the level and the distance corresponding to each occupant's physique, regardless of the physique of the occupant sitting on the seat. There is an advantage that 置感 mounting to operability and pedals the pedals due can be kept constant remains good.

  On the other hand, the pedal position adjusting mechanism 40 adjusts the relative position of the pedal 8 with respect to the seat 7 including adjusting the inclination of the tread surface and adjusting the height of the tread surface according to the position of the seat 7. A plurality of 40a, 40b, and 40b are provided according to 8b and 8c. The pedals 8 whose positions are adjusted by the pedal position adjusting mechanism 40 are respectively rotated about a support shaft 44 that is an operation center axis, and each pedal 8 is arranged as follows.

  That is, as shown in FIGS. 3 and 6, the pedal 8 is provided with an accelerator pedal 8a, a brake pedal 8b, and a clutch pedal 8c from the right side in the vehicle width direction, and the support shaft 44 of the brake pedal 8b and the clutch pedal 8c is connected to the vehicle. On the other hand, the support shaft 44 of the accelerator pedal 8a is arranged so as to be slightly inclined in the front-rear direction from the axis parallel to the vehicle width direction. In this embodiment, the accelerator pedal 8a adjusts the relative position of the accelerator pedal 8a relative to the seat 7 such as the inclination angle and the height of the tread by rotating the tread about the support shaft 44 of the pedal 8a. Yes. On the other hand, the brake pedal 8b and the clutch pedal 8c do not adjust the relative positions around the support shaft 44, which is the operation center axis, but the support shaft 44 of the accelerator pedal 8a, strictly speaking, the support of the accelerator pedal 8a. The relative position with respect to the seat 7 is adjusted around an axis parallel to the vehicle width direction passing through the substantially central portion of the shaft 44 in the vehicle width direction. That is, in this embodiment, the support shaft 44 of the accelerator pedal 8a as a reference pedal is configured to substantially coincide with the rotation adjustment center shaft 10. The accelerator pedal position adjusting mechanism 40a cooperates with the floor position adjusting mechanism 30 so that the inclination angle between the tread surface of the accelerator pedal 8a and the saddle placement surface of the movable floor panel 9 is the position of the accelerator pedal 8a. Regardless, it is configured to be maintained substantially constant at an initial setting position to be described later.

  Here, the support shaft 44 of the brake pedal 8b is provided at a position displaced upward and forward with respect to the support shaft 44 of the accelerator pedal 8a (see FIG. 13), while the support shaft 44 of the clutch pedal 8c is It is provided between the support shaft 44 of the brake pedal 8b and the support shaft 44 of the accelerator pedal 8a. In this way, the support shaft 44 of the brake pedal 8b is provided at a relatively high position, and later-described levers 42 and 43 of the brake pedal 8b are set long, and the brake pedal 8b is disposed at substantially the same height as the accelerator pedal 8a. While ensuring the operation force of the brake pedal 8b, the feeling of stepping with the accelerator pedal 8a and the operability at the time of step change are improved.

  Further, the positional relationship of the pedal surfaces 48a, 48b, 48c, which will be described later, of the pedals 8a, 8b, 8c that are directly depressed by the occupant's feet will be described. A predetermined step along the front-rear direction of the vehicle body between the accelerator pedal 8a and the brake pedal 8b is disposed on the seat side and slightly above the tread surface portion 48a with respect to the tread surface portion 48a of the pedal 8a. (See FIG. 13), the tread surface portion 48c of the clutch pedal 8c is on the opposite side (front) to the seat side with respect to the tread surface portion 48a of the accelerator pedal 8a as a reference pedal, and the tread surface portion 48a. A predetermined step along the longitudinal direction of the vehicle body between the accelerator pedal 8a and the clutch pedal 8c. It is formed. The footrest 51 is disposed on the side opposite to the seat side with respect to the tread surface portion 48a of the accelerator pedal 8a and slightly below the tread surface portion 48a, and between the accelerator pedal 8a and the footrest 51, the vehicle body is also disposed. A predetermined step along the front-rear direction is formed.

  The reference pedal position adjusting mechanism 40a of the reference pedal (accelerator pedal 8a) and the predetermined pedal position adjusting mechanism 40b of the pedals as the stepping bodies (brake pedal 8b, clutch pedal 8c) are as described above. Although the position of the rotation adjustment center axis 10 is different depending on whether or not the position of the rotation adjustment center axis 10 coincides with the support axis 44 that is each operation center axis, the pedal position adjustment mechanism corresponding to the accelerator pedal 8a is used here. A description will be given by taking 40a as an example.

  That is, the accelerator pedal 8a is disposed at a pedal bracket 41 attached to the dash lower panel 4, a pedal lever as a pedal position adjusting mechanism 40a pivotally supported by the pedal bracket 41, and a lower end portion of the pedal lever. A tread surface portion 48a is provided, and an operation mechanism (not shown) is operated at a predetermined pedal ratio via a wire, a rod, or the like attached to the pedal lever by depressing the tread surface portion 48a. Here, the pedal ratio means a value obtained by dividing the length from the tread surface portion 48a to the support shaft 44 by the length from the support shaft 44 to the operation mechanism (not shown), and the operation force decreases as this value increases. Increased operating stroke. In this embodiment, since the distance from the support shaft 44 to the master cylinder does not change, the pedal ratio is determined by the length from the tread surface 48a to the support shaft 44. Examples of the operation mechanism include a throttle valve and a fuel adjustment mechanism in the accelerator pedal 8a, a master cylinder as the brake pedal 8b, and an operation lever of a clutch plate as the clutch pedal 8c.

  Unlike a normal pedal lever, the pedal position adjusting mechanism 40 is configured to be able to change the relative position of the lower half of the lever with respect to the upper half of the lever. By changing the relative position, the inclination angle, the tread height, etc. The relative position with respect to the sheet 7 is changed.

  That is, as shown in FIGS. 6 to 8, the pedal position adjusting mechanism 40a includes an upper lever 42 that is pivotally supported by the pedal bracket 41 and a lower lever that can change the relative position with respect to the upper lever 42. 43. The upper lever 42 is formed in a pendulum shape, and includes an upper main body 42a extending vertically and a guide portion 42b provided at a lower end portion of the upper lever 42. The guide portion 42b has the rotation adjustment center shaft 10 as a center. A guide groove 42c formed in an arc shape is formed. On the other hand, the lower lever 43 is formed in an arc shape centered on the rotation adjustment center axis 10 at the upper end portion of the lower main body 43a and the lower main body 43a curved in an arcuate shape and provided with a tread surface portion 48a at the lower end portion. The slider 43b is fitted into the guide groove 42c, and the slider 43b slides along the arcuate track of the guide groove 42c so that the lower lever 43 can be attached to the upper lever 42 so that the relative position can be changed. It has been. Note that the slide stroke for adjusting and rotating the pedals 8a, 8b, and 8c is set to be shorter in the order of the accelerator pedal 8a, the brake pedal 8b, and the clutch pedal 8c.

  Specifically, as shown in FIGS. 6 and 8, the guide portion 42 b is formed in a substantially C shape in a sectional view to form a guide groove 42 c. The slider 43b fitted in the guide groove 42c has a rack portion 43c formed on the side surface in the opening direction of the guide groove 42c (left side surface in FIG. 6). A worm 45 meshes with the rack portion 43c, and the slider 43b having the rack portion 43c slides along the arc shape of the guide groove 42c when the worm 45 rotates forward and backward. Therefore, the slide stroke for adjusting the position of the pedal 8 can be adjusted to be long or short by adjusting the length of the rack portion 43c. The worm 45 is connected to a flexible power transmission shaft 46 and a drive motor 47, and the drive motor 47 receives the output of the ECU 70 and rotates forward and backward. Then, as shown in FIG. 2, when the pedal position adjusting mechanism 40a is at the L position, the pedal position adjusting mechanism 40a is rotated downward about the support shaft 44 so that the relative distance from the seat 7 is increased (see FIG. 2). On the other hand, when it is in the S position, it is rotated upward about the support shaft 44, and after passing through the PM position set so as to fit a standard physique and body type passenger, Driving is performed so that the relative distance becomes shorter (PS in FIG. 2). Further, the accelerator pedal 8a is provided with its support shaft 44 inclined slightly from an axis parallel to the vehicle width direction, so that the drive motor 47 is driven to shift from the L position to the S position. Thus, the distance between the brake pedal 8b and the vehicle width direction is reduced.

  The drive motor 47 can also be driven by, for example, a pedal position adjustment switch 47a (see FIG. 7) provided on the instrument panel 5 for each pedal. A pedal position sensor 49 that detects the position of the pedal 8 by detecting the rotational speed of the drive motor 47 is provided, and the detection result is output to the ECU 70. The pedal position sensor 49 is also composed of a known sensor such as an encoder, like the seat position sensor 15.

  When adjusting the relative positions of the pedals 8 and the footrest 51, the drive motors 47 are driven in response to outputs from a position control means 71 (to be described later) of the ECU 70, and the drive amounts by the drive motors 47 are adjusted. Thus, the relative position between the pedals 8 is adjusted. The relative position adjustment between the pedals 8 will be described later.

  On the other hand, the footrest position adjustment mechanism 50 adjusts the relative position of the footrest 51 with respect to the seat 7 and the accelerator pedal 8a, including the adjustment of the tread surface inclination and the tread height, according to the position of the seat 7. The position is adjusted by rotating around the dynamic adjustment center shaft 10, specifically, the support shaft 44 of the accelerator pedal 8a.

  The footrest 51 is disposed below and forward of the accelerator pedal 8a, in other words, below the left side of the clutch pedal 8c, with a predetermined level difference provided along the longitudinal direction of the accelerator pedal 8a and the vehicle body, and operates the clutch pedal 8c. The occupant's foot is placed when the clutch pedal 8c is not operated. As shown in FIG. 9, the footrest 51 is a plate-like member formed of a metal plate or a hard synthetic resin plate, and is supported by a bracket as a footrest position adjusting mechanism 50 attached to the floor panel 3. Yes. Unlike the normal bracket, the footrest position adjusting mechanism 50 is configured to be able to change the relative position of the slider 55 to which the footrest 51 is attached with respect to the bracket body 52 attached to the floor panel 3. The relative position of the footrest 51 with respect to the accelerator pedal 8a is changed.

  That is, as shown in FIG. 9, the footrest position adjusting mechanism 50 includes a bracket body 52 attached to the floor panel 3, a slider 55 configured to change a relative position with respect to the bracket body 52, and the bracket A drive motor 53 is mounted on a surface opposite to the slider 55 with respect to the main body 52 and drives the slider 55 to slide.

  Specifically, the bracket body 52 has a flange portion 52c formed by bending a lower end portion thereof, which is superposed on the floor panel 3, and this superposed portion is bolted or spot-welded to cause the floor panel 3 to be bent. Is attached. The bracket body 52 has a side-opening type guide groove 52 a formed by a pair of upper and lower guide rail portions, and the guide groove 52 a is formed in an arc shape centering on the rotation adjustment center axis 10. . A slider 55 formed in an arc shape centering on the rotation adjustment center shaft 10 is fitted in the guide groove 52a. A footrest 51 is attached to the slider 55 via a support arm 56 extending from the side surface, and a rack portion 55a is engraved at a lower end portion of the slider 55 over a predetermined range. A worm portion 57 attached to the output shaft of the drive motor 53 is engaged with the rack portion 55a. When the worm portion 57 is rotated forward and backward by the drive motor 55, the slider 55 having the rack portion 55a is guided to the guide groove 52a. It is supposed to slide along the arc trajectory.

  The drive motor 53 is attached to the side surface of the bracket body 52 opposite to the guide groove 52a, and the worm portion 57 attached to the output shaft passes through the bracket body 52 in the thickness direction and communicates with the guide groove 52a. The communication hole 52b is configured to mesh with the rack portion 55a of the slider 55. The drive motor 53 is driven to rotate forward and backward in response to the output of the ECU 70, and is also driven by, for example, a footrest position adjustment switch 53a (see FIG. 10) provided on the instrument panel 5. A footrest position sensor 54 that detects the position of the footrest 51 by detecting the rotational speed of the drive motor 53 is provided, and the detection result is output to the ECU 70. Similarly to the seat position sensor 15, the footrest position sensor 54 is configured by a known sensor such as an encoder.

  The target position of the footrest 51 is determined in the ECU 70 as described later. When the footrest position adjusting mechanism 50 is in the L position, the slider 55 is moved forward of the vehicle body to increase the relative distance from the seat 7. On the other hand, when in the S position, the slider 55 is moved to the rear side of the vehicle body, that is, the seat 7 side so that the relative distance from the seat 7 is shortened. At this time, the amount of movement of the footrest 51 is the same as the amount of movement of the clutch pedal 8c, so that the relative distance between the footrest 51 and the clutch pedal 8c is kept constant, and the level difference between the footrest 51 and the accelerator pedal 8a is reduced. As a result, the ECU 70 adjusts the movement amount to be larger than the movement amount of the accelerator pedal 8a. In addition, since the guide groove 52a and the slider 55 are formed in an arc shape in the footrest position adjusting mechanism 50, the inclination angle of the tread surface of the footrest 51 is also changed as the slider 55 moves.

  FIG. 10 is a block diagram showing the configuration of the drive and control system of the driving posture adjusting apparatus having the above configuration. The ECU 70 includes a CPU that executes various arithmetic processes, a ROM (Read Only Memory) that stores various initial settings, and a RAM (Random Access Memory) that stores various types of input information that can be overwritten. Yes, the target position (including the angle) of the pedal 8, the footrest 51, and the movable floor panel 9 is specified from the predetermined target position map based on the detection result from the seat position sensor 15, and the pedal 8, The pedal position adjustment mechanism 40, the footrest position adjustment mechanism 50, and the floor position adjustment mechanism 30 are adjusted and controlled so that the footrest 51 and the movable floor panel 9 move. In addition, the ECU 70 displays predetermined items such as guidance at the time of position adjustment in the position adjustment mechanisms 30, 40, 50 on the display means 100 configured as a display screen of the car navigation system. .

  A plurality of the predetermined target position maps are provided corresponding to the in-vehicle members 8, 9, 51, and in particular, the pedal 8 and the footrest 51 are provided for each pedal and the like. That is, in each target position map, as shown in FIG. 11, the target positions of the accelerator pedal 8a, the brake pedal 8b, the clutch pedal 8c, the footrest 51, and the movable floor panel 9 are determined corresponding to the position of the seat 7. In the initial setting, the positions of the pedals 8, the footrest 51, and the movable floor panel 9 that are adapted to the occupant are determined with reference to the occupant having a standard body shape that is seated on the seat 7 at a predetermined position. Further, this target position map is set so that the steps of the other pedals 8b and 8c and the footrest 51 with respect to the accelerator pedal 8a are reduced as the accelerator pedal 8a as the reference pedal moves in the direction approaching the seat 7 side. Yes. That is, when the accelerator pedal 8a moves toward the seat 7 side, the amount of movement of the brake pedal 8b is set smaller than the amount of movement of the accelerator pedal 8a, and the amount of movement of the clutch pedal 8c and the footrest 51. Is set larger than the amount of movement of the accelerator pedal 8a. In FIG. 11, the respective positions of the pedals 8 and the like are shown in a state where the target positions are defined in one target position map for convenience of explanation.

  Further, the ECU 70 drives the various drive motors 39, 47, 53 according to the operation amount in response to a request from the occupant, that is, when the various position adjustment switches 39a, 47a, 53a are operated by the occupant. The position of the in-vehicle members 8, 51, 9 is adjusted, and when there is an input from the adjustment determination switch 91, the position of the in-vehicle members 8, 51, 9 is stored in the storage means 80 as an individual set position. In addition, the sheet position corresponding to the individual set position is stored in the storage unit 80 as the specific sheet position.

  Specifically, the ECU 70 includes a position control unit 71, a map correction unit 72, and a storage unit 80. The ECU 70 receives signals as detection results from the various position sensors 15, 38a, 49, 54, and various types. Command signals are input from the switches 39a, 47a, 53a, and further connected to the display means 100 configured as a touch panel, and various instructions can be input from the touch panel switch provided on the screen of the display means 100. Yes.

  The position control means 71 detects the current position of the seat 7 based on a signal input from the seat position sensor 15 when the position of the seat 7 is changed, and the pedal 8 and the footrest corresponding to the position of the seat 7. 51 and the target position of the movable floor panel 9 are specified from each target position map stored in the storage means 80, and the movement amount from the current position of the pedal 8, the footrest 51 and the movable floor panel 9 to the target position is calculated. Based on the calculation result, the pedal position adjusting mechanism 40, the footrest position adjusting mechanism 50 and the floor position adjusting mechanism 30, and more specifically, the position sensors 49, 54 and 38a are checked while driving the position adjusting mechanisms 40, 50 and 30. The motors 47, 53 and 39 are controlled.

  Here, the target position map will be specifically described. When the individual setting position is not set, the target position map shows the pedal 8 and footrest according to the occupant's body shape in the standard ratio of each physique (for example, the ratio of sitting height to foot length) according to the seat position 51 and an initial setting map representing the position of the movable floor panel 9 (see FIG. 11), and the locus of the seat position, the pedal position, the footrest position, and the floor position change continuously while maintaining a proportional relationship. (Change characteristic line). In particular, the change trajectory of the accelerator pedal 8a as a reference pedal (trajectory indicated by a solid line in FIG. 11), the change trajectory of the brake pedal 8b and the clutch pedal 8c as trajectories (trajectory indicated by a broken line in FIG. 11), and When attention is paid to the relationship with the change trajectory of the footrest 51 as the stepped body (the trajectory indicated by the alternate long and short dash line in FIG. 11), the change rate in each change trajectory is different, and the accelerator pedal 8a is based on the seat position change. The steps with the other pedals 8b, 8c, 51 are configured to be enlarged or reduced. That is, with respect to the brake pedal 8b disposed on the seat 7 side with respect to the accelerator pedal 8a, the change rate is set to be smaller than the change rate of the accelerator pedal 8a. About the clutch pedal 8c and the footrest 51 which are arrange | positioned on the opposite side to the sheet | seat 7, the change rate is set so that it may become large compared with the change rate of the accelerator pedal 8a.

Accordingly, the brake pedal 8b will be described as an example. As shown in FIG. 11, when the seat 7 is moved to the front side, the height of the accelerator pedal 8a is increased accordingly, and the height of the brake pedal 8b is also increased. To do. However, since the rising width of the brake pedal 8b is set smaller than that of the accelerator pedal 8a, the step between the accelerator pedal 8a and the brake pedal 8b is reduced, and the initial step d ₀ when the seat 7 is at the rearmost position. Even when the seat 7 is formed, when the seat 7 is in the foremost position, the step d ₁ (d ₁ <d ₀ ) where the step between the accelerator pedal 8a and the other pedals 8b, 8c, 51 is smaller than the initial step. It is supposed to move to.

  That is, in the target position map of these pedals 8a, 8b, 8c, 51, as the accelerator pedal 8a moves toward the seat 7, the steps of the stepped bodies 8b, 8c, 51 with respect to the reference pedal 8a are reduced. It is configured as follows.

  The position control means 71 constantly monitors the seat position, and is configured to move the pedal 8, the footrest 51 and the movable floor panel 9 immediately when the seat 7 is moved. Specifically, the position control means 71 detects the position of the sheet 7 from the sheet position sensor 15 at a predetermined time interval, stores this detection position in the storage means 80 as a memory position, and this memory position is set as the next detection position. In comparison, it is determined whether or not they are the same. If they are the same, it is determined that the sheet 7 is stopped. It is supposed to constantly monitor the movement and stoppage. Further, the positioning control of each part 8, 51, 9 is also executed in the same manner as this sheet position, and the detection position by the position sensors 49, 54, 38a at a predetermined time is stored in the storage means 80 as a memory position. The movement and stop of the pedal 8, the footrest 51 and the movable floor panel 9 are detected by comparing the memory position with the next detection position.

  The map correction means 72 corrects a target position map that determines a reference for control by the position control means 71 in response to a passenger's request. That is, the map correction means 72 is operated when the position adjustment switches 47a, 53a and 39a are operated after the position control means 71 performs automatic control of the positions of the pedal 8, the footrest 51 and the movable floor panel 9. The position of the seat 7 when the adjustment determination switch 91 is input by operating is set as the specific seat position, and the positions of the pedal 8, the footrest 51, and the movable floor panel 9 are individually set positions of the in-vehicle members 8, 51, 9 Are stored in the storage unit 80, and at least the positions of the pedal 8, the footrest 51, and the movable floor panel 9 at the specific seat position are individually set from the initial setting position of the pedal 8, the footrest 51, and the movable floor panel 9. Configured to correct the target position map stored in the position That. This target position map is configured to be able to be initialized, and when it is initialized, the initial setting position is read from the storage means 80 and overwritten and corrected.

  There are various ways of correcting the target position map, and an example will be described here. That is, when the individually set position is set for each of the in-vehicle members 8a and 9 according to the request of the occupant, only the position of the in-vehicle members 8a and 9 for the specific seat position a is from the initial set positions M1 and M2. It is configured to be changed to the individual setting positions N1, N2. Accordingly, the respective portions 8a and 9 at the specific sheet position a are aligned with the individual set positions N1 and N2, while when the target position map is initialized, the respective portions 8a and 9 at the specific sheet position a are initialized. Aligned to M1 and M2. The same applies to the brake pedal 8b, the clutch pedal 8c, and the footrest 51. Further, when the individual setting position is set for any one of the pedals 8a, 8b, 8c, 51 and the movable floor panel 9, only the target position map of the vehicle-mounted member in which the individual setting position is set is obtained. It is configured to be corrected.

  On the other hand, the storage unit 80 includes a ROM and a RAM, and stores target position map information serving as a reference for adjusting the positions of the pedal 8, the footrest 51, and the movable floor panel 9, as shown in FIG. In addition to the target position map information, when individual set positions are set for the pedal 8, the footrest 51, and the movable floor panel 9, the positions of the pedal 8, the footrest 51, and the movable floor panel 9 when set Are stored as individual setting information, and the sheet position where the individual setting position is set is stored as specific sheet position information in association with the individual setting information. In addition, the initial setting position information of the pedal 8, the footrest 51, and the movable floor panel 9 serving as an initial setting map is stored in the ROM area of the storage unit 80. Furthermore, the storage means 80 is provided with a temporary storage unit (not shown) that stores the detected positions of the seat 7, pedal 8, footrest 51, and movable floor panel 9 as memory positions. The target position map information, the individually set position information, and the specific sheet position information are stored in the RAM area of the storage unit 80. Of these, the target position map information is rewritten as needed by the map correction unit 72, and the individual set position information and the specific position information are stored. The seat position information is erased in response to a passenger's request, for example, by pressing a reset switch (not shown).

  Control of the driving posture adjusting apparatus having the above configuration, particularly control in the ECU 70, will be described based on a flowchart.

  The flowchart shown in FIG. 12 shows the basic control of the driving posture adjusting apparatus of this embodiment. The processing shown in this flowchart is started when the ignition switch is turned on. First, whether the sheet 7 is moving by comparing the memory position stored in the storage unit 80 with the detection position from the sheet position sensor 15. It is determined whether or not (step SS1). If it is determined that the seat 7 is moving, the target positions of the pedal 8, the footrest 51 and the movable floor panel 9 corresponding to the position of the seat 7 are read from the target position map, and the respective parts 8, 51, 9, the position sensors 49, 54, and 38 a confirm the positions so that the positions of 9 are aligned, and the drive motors 47, 53, and 39 are driven to perform automatic position adjustment of the in-vehicle members 8, 51, and 9. (Step SS2). Specifically, the accelerator pedal 8a and the movable floor panel 9 will be described as an example. When the position of the seat 7 is at the specific seat position a in the target position map shown in FIG. The position is adjusted to be the setting positions N1 and N2. On the other hand, when the seat position is other than the specific seat position a, the position of the accelerator pedal 8a and the movable floor panel 9 is adjusted so as to be the initial setting position.

  Following this step SS2 or if NO is determined in step SS1, the process proceeds to step SS3 to determine whether or not the position adjustment switches 47a, 53a, 39a of the respective parts 8, 51, 9 are operated, When this operation is performed, it is recognized that the positions of the pedal 8, the footrest 51, and the movable floor panel 9 have been finely adjusted according to the occupant's body shape and preferences. In this fine adjustment, the pedal 8, the footrest 51, and the movable floor panel 9 are moved according to the operation amount of each position adjustment switch 47a, 53a, 39a (step SS4). Specifically, each of the position adjustment switches 47a, 53a, 39a is provided with a switch for driving the drive motors 47, 53, 39 in the forward rotation direction and a switch for driving in the reverse rotation direction. The position of each part 8, 51, 9 is adjusted by rotationally driving each drive motor 47, 53, 39 in the forward direction or the reverse direction. When the pedal 8, the footrest 51, and the movable floor panel 9 are adjusted to desired positions and the adjustment determination switch 91 is pressed by the occupant, the positions of the respective parts 7, 8, 51, 9 including the seat 7 are specified seats. The position and each individual setting position are stored in the storage unit 80. The positions of these parts 7, 8, 51, 9 are stored in the storage means 80 as memory positions, and the process returns. On the other hand, if it is determined NO in step SS3, the process skips step SS4 and returns.

  The adjustment of the relative position between the reference pedal and the stepping body by the driving posture adjusting apparatus having the above configuration will be described by taking the accelerator pedal 8a and the brake pedal 8b as examples.

  FIG. 13 is an explanatory diagram showing the relative positional relationship between the accelerator pedal 8a and the brake pedal 8b. FIG. 14 is an explanatory view showing only the brake pedal in FIG. FIG. 15 is a diagram showing the relationship between the step between the accelerator pedal and the brake pedal and the pedal ratio of the brake pedal with respect to the seat position. In FIGS. 13 and 14, the accelerator pedal and the brake pedal are shown with the pedal position adjusting mechanism omitted.

  In FIG. 13, the positions of the accelerator pedal 8a and the brake pedal 8b when the seat 7 is at the rearmost end, that is, the position farthest from the pedal 8, are indicated by solid lines, and the tread surface portion 48a, 48b is indicated by a two-dot chain line.

  As shown in FIG. 13, the accelerator pedal 8a is operated to rotate around a support shaft 44 (center O1 in the figure). Move. As described above, the accelerator pedal 8a has a rotation adjustment center axis coincident with the operation center axis at the time of position adjustment (since the rotation adjustment is performed around O1 in the figure), the seat 7 Is moved forward, the predetermined point of the tread surface 48a is also moved from the point A1 to the point A2 along the track L1 in the direction of approaching the occupant seated on the seat 7 as indicated by the white arrow Y1. Adjusted. When adjusting the position of the accelerator pedal 8a, the rotation adjustment center axis at the time of position adjustment coincides with the operation center axis. Therefore, the pedal ratio is not changed, and the pedal operation amount and operation feeling are kept constant. The position adjustment can be executed while holding.

  On the other hand, the brake pedal 8b is operated to rotate around a support shaft 44 (center O2 in the figure), and moves along the track L2 when the tread surface portion 48b is stepped on by the occupant's feet. As described above, the pivot adjustment central axis of the brake pedal 8b is adjusted to the support shaft 44 (center O1 in the drawing) of the accelerator pedal 8a, so that the seat 7 is moved forward. Then, as indicated by the black arrow Y2, the predetermined point of the tread surface portion 48b moves from the point B1 to the point B2 along the track L3 and is adjusted in the direction approaching the occupant seated on the seat 7.

Here, when the position is adjusted with the same movement amount as that of the accelerator pedal 8a, the tread surface 48b moves to the position indicated by the dotted line, that is, the point B1 moves to the point B3, but the movement amount is smaller than the accelerator movement amount. Since it is set, that is, the rate of change is small, the step d _x with respect to the accelerator pedal 8a is reduced from the initial value d ₀ . In addition, since the support shaft 44 of the accelerator pedal 8a is arranged slightly inclined in the front-rear direction, the distance in the vehicle width direction from the brake pedal 8b is reduced as the accelerator pedal 8a is raised.

  For this reason, as the seat 7 is moved forward, that is, as the physique of the occupant seated on the seat 7 becomes smaller, the step and the gap of the brake pedal 8b with respect to the accelerator pedal 8a are also reduced, so that the occupant seated on the seat 7 The step and spacing of the brake pedal 8b relative to the accelerator pedal 8a can be adjusted according to the physique (foot size, length, etc.). Regardless of the physique of the occupant sitting on the seat 7, the operability of each pedal 8 by the occupant and the feeling of placement on the pedal 8 can be kept constant. Further, since the movement amount of the clutch pedal 8c and the footrest 51 is set larger than the movement amount of the accelerator pedal 8a, the steps and intervals between these pedals 8c, 51 and the accelerator pedal 8a are reduced, The same effect is produced.

  Further, as in the conventional driving posture adjusting device, when the brake pedal 8b is rotated and adjusted around the center O1 by the same amount of movement as the accelerator pedal 8a, the tread surface portion 48b is moved to the operation track L2 ′ as shown in FIG. Therefore, the length of the brake pedal 8b from the tread surface portion 48b to the support shaft 44 is changed from R1 to R3 (R1> R3). As a result, the pedal ratio may change, and the operability, placement feeling, etc. may change significantly.

  For this reason, in the driving posture adjusting apparatus of the present embodiment, since the amount of movement of the brake pedal 8b is set smaller than the amount of movement of the accelerator pedal 8a, changes in the pedal ratio can be suppressed as much as possible. Therefore, the uncomfortable feeling with respect to the operability and the placement feeling of the brake pedal 8b can be suppressed as much as possible. In addition, since the tread surface portion 48b of the brake pedal 8b as the stepped body is disposed on the seat 7 side with respect to the tread surface portion 48a of the accelerator pedal 8a as the reference pedal, the brake pedal 8b linked to the movement of the accelerator pedal 8a is arranged. The relative distance between the two can be shortened simply by reducing the amount of movement, whereby the step can be reduced easily and quickly. In contrast, the clutch ratio of the clutch pedal 8c and the footrest 51 changes greatly. However, since these pedals 8c and 51 are not pedals that can be switched from the accelerator pedal 8a as a reference pedal, the operability and placement of the pedals are not limited. There is little need for security such as feeling, and conversely, the step between the pedals 8c and 51 is kept constant in order to maintain good switching between the clutch pedal 8c and the footrest 51.

  That is, in the driving posture adjusting apparatus of this embodiment, as shown by a solid line in FIG. 15, a conventional driving posture adjusting device that moves the accelerator pedal 8a and the brake pedal 8b by the same movement amount (shown by a dotted line in FIG. 15). ), The pedal step difference can be reduced at the same time while suppressing the pedal ratio change of the brake pedal 8b as much as possible. Thus, regardless of the physique of the occupant sitting on the seat 7, The operability and the feeling of placing on the pedal can be kept constant. In addition, since it is rotated around the same rotation center axis 10 (rotation adjustment center axis), the driving posture of the occupant can be rotated around the rotation adjustment center axis 10 and placed on each pedal 8. A feeling can be kept constant.

  The driving posture adjusting apparatus described above is an embodiment of the apparatus according to the present invention, and the specific configuration and the like of the apparatus can be appropriately changed without departing from the gist of the present invention. Is described below.

  (1) In the above embodiment (the first embodiment), the driving posture adjusting device for an automobile having a so-called manual transmission on which the clutch pedal 8c is mounted has been described. The present invention can also be applied to an automobile having a so-called automatic transmission with no gear.

  That is, FIG. 16 is a front view showing a second embodiment of the driving posture adjusting apparatus for an automobile. FIG. 17 is a plan view showing the second embodiment. In these drawings, the sheet 7 and the like are not shown, but the basic configuration is the same as that of the first embodiment shown in FIGS. 1 and 2.

  The driving posture adjusting device includes a seat 7, pedals 8, a footrest 151, a movable floor panel 9, a seat position adjusting mechanism 20 that adjusts the position of the seat 7, and a floor that adjusts the position of the movable floor panel 9. The position adjusting mechanism 30, a plurality of pedal position adjusting mechanisms 40 for adjusting the positions of the accelerator pedal 8a and the brake pedal 8b, and the floor position adjusting mechanism 30 and each pedal position adjusting mechanism 40 are connected to the seat 7 or the accelerator pedal 8a. ECU (electrical control unit) 70 that controls based on the position, and changes the relative position (including relative angle) between the seat 7, the accelerator pedal 8a and the movable floor panel 9, and changes the accelerator pedal 8a. Accordingly, the relative position between the accelerator pedal 8a and the brake pedal 8b is changed, and the movable flow is With the change of the relative position of the rear panel 9, the position of the occupant seated on the seat 7 is adjusted by changing the relative position of the seat 7 and the footrest 51. As described above, the basic configuration of the driving posture adjusting apparatus according to the second embodiment is the same as that of the first embodiment, and there is no clutch pedal 8c, and the position adjusting mechanism of the footrest 151 according to the first embodiment. And different. Hereinafter, this different point will be described with emphasis, and the same components are denoted by the same reference numerals in the drawings, and description thereof will be omitted.

  Also in the driving posture adjusting apparatus according to the second embodiment, the accelerator pedal 8a is set as a reference pedal, and the brake pedal 8b and the footrest 151 are set as stepping bodies.

  Unlike the first embodiment, the footrest 151 is not adjusted in position by the footrest position adjusting mechanism 50, but is attached to the movable floor panel 9 to perform the position adjustment of the movable floor panel 9. The position adjustment is performed by the adjustment mechanism 30. Specifically, the footrest 151 is inclined from the upper surface of the movable floor panel 9 to the upper surface at the front end of the movable floor panel 9 on the left side in the vehicle width direction (the side opposite to the accelerator pedal 8a side). It protrudes and is configured to be movable integrally with the movable floor panel 9. Therefore, the position adjustment mechanism of the footrest 151 also serves as the floor position adjustment mechanism 30 that is the position adjustment mechanism of the movable floor panel 9, and the floor position adjustment mechanism 30 and the ECU 70 correspond to the stepped body position adjustment means in the claims. .

  Since the floor position adjustment mechanism 30 also serves as a footrest position adjustment mechanism, the ECU 70 is also slightly different. Accordingly, the movable floor panel 9 is moved in a direction close to the accelerator pedal 8a, that is, the movable floor panel 9 is raised.

  If comprised in this way, with the raise of the movable floor panel 9, the mounting stability of the foot part with respect to the passenger | crew with a small physique will improve, and, thereby, the accelerator pedal 8a and brake pedal 8b which are operated by this foot part are improved. Operability is also improved. Further, by providing the footrest 151 on the movable floor panel 9, it is possible to further improve the mounting property of the foot while simplifying the apparatus.

  (2) Regarding the positional relationship between the reference pedal (accelerator pedal 8a in the first embodiment) and the stepping body (other pedals 8b, 8c, 51 in the first embodiment), the first and second It is not limited to what concerns on embodiment, Various aspects can be employ | adopted. For example, you may employ | adopt the arrangement | positioning aspect as shown to each following figure. In these figures, the accelerator pedal 8a and the brake pedal 8b will be described as an example. In these drawings, the operation center axis of the pedal that is the rotation adjustment center axis is indicated by O1 (including O11 and O12), the operation center axis of the pedal that is not the rotation adjustment center axis is indicated by O2, The tread surfaces 48a and 48b after the positions of the pedals 8a and 8b are adjusted are indicated by two-dot chain lines.

  FIG. 19 is an explanatory diagram showing a modification of the arrangement of the accelerator pedal 8a as a stepped body and the brake pedal 8b as a reference pedal. That is, unlike the first embodiment, the brake pedal 8b is set as a reference pedal, and the position of the accelerator pedal 8a is adjusted in conjunction with the position adjustment of the brake pedal 8b. The accelerator pedal 8a is disposed behind the brake pedal 8b, that is, the stepped body is disposed on the seat 7 side with respect to the reference pedal.

  In the example shown in FIG. 19, the operation center shaft 44 of the accelerator pedal 8a is disposed behind and below the operation center shaft 44 of the brake pedal 8b. This is different from the first embodiment in that the position is adjusted at the center.

  In the example shown in FIG. 19, in the L position, the accelerator pedal 8a is operated along the track L7 and the brake pedal 8b is operated along the track L5. As the seat 7 is adjusted forward, the positions of the pedals 8a and 8b are rotated and adjusted around the rotation adjustment center O1, for example, along with the position adjustment of the pedals 8a and 8b. When the predetermined point B1 of the brake pedal 8b moves to the point B2 along the track L5, the predetermined point A1 of the accelerator pedal 8a also moves to the point A2 along the circular arc track L4 centered on O1. The amount of movement of the accelerator pedal 8a is set to be larger than the amount of movement of the brake pedal 8b, thereby reducing the step in the front-rear direction between the accelerator pedal 8a and the brake pedal 8b. The accelerator pedal 8a is operated along the track L6 after the position adjustment, and therefore the pedal ratio of the accelerator pedal 8a is changed relatively large (see FIG. 20).

  However, even in this case, as the brake pedal 8b moves closer to the seat 7, that is, the step in the front-rear direction of each pedal 8a, 8b is reduced, the physique (foot) of the passenger sitting on the seat 7 is reduced. The step of the accelerator pedal 8a with respect to the brake pedal 8b can be adjusted in accordance with the size and length of the part, so that the step corresponding to the physique of each occupant can be set to the physique of the occupant seated on the seat 7 Regardless, the operability of the pedals 8a and 8b by the occupant and the feeling of placement on the pedals 8a and 8b can be maintained constant.

  FIG. 21 is an explanatory diagram showing another modification of the arrangement of the accelerator pedal 8a as a reference pedal and the brake pedal 8b as a stepping body.

  In the example shown in FIG. 21, although the arrangement relationship of the operation center shafts 44 of both pedals 8a and 8b is the same as that of the first embodiment, both pedals 8a and 8b are operated center shafts 44 of the pedals 8a and 8b. Is different from the first embodiment in that the position is adjusted around the center. In addition, this example is different from the first embodiment in that the tread surface portion 48a of the accelerator pedal 8a is disposed rearward (seat 7 side) than the tread surface portion 48b of the brake pedal 8b.

  In the example shown in FIG. 21, at the L position, the accelerator pedal 8a is operated along the track L8, and the brake pedal 8b is operated along the track L9. As the seat 7 is adjusted forward, the positions of the pedals 8a and 8b are adjusted around the rotation adjustment centers O11 and O12. For example, the position of the pedals 8a and 8b is adjusted. When the predetermined point A1 of the accelerator pedal 8a also moves to the point A2 along the track L8, the predetermined point B1 of the brake pedal 8b moves to the point B2 along the track L9. The amount of movement of the brake pedal 8b is set to be larger than the amount of movement of the accelerator pedal 8a, thereby reducing the step in the front-rear direction between the accelerator pedal 8a and the brake pedal 8b. The pedals 8a and 8b are operated along the tracks L8 and L9 even after the position adjustment, so that the pedal ratio of the brake pedal 8b as a stepping body is constant before and after the position adjustment (see FIG. 22).

  Even in this case, as the accelerator pedal 8a moves closer to the seat 7, that is, when the pedal 8a, 8b moves rearward, the step in the front-rear direction of the pedal 8a, 8b is reduced. The step of the brake pedal 8b with respect to the accelerator pedal 8a can be adjusted in accordance with the size and length of the accelerator pedal 8a. The operability of the pedals 8a and 8b by the occupant and the feeling of placement on the pedals 8a and 8b can be kept constant while being good. In addition, since the position is adjusted around the operation center axes O11 and O12, the pedal ratios of the pedals 8a and 8b can be kept constant, whereby the operation amounts of the pedals 8a and 8b can be kept constant. .

  FIG. 23 is an explanatory view showing still another modified example of the arrangement of the accelerator pedal 8a as a stepped body and the brake pedal 8b as a reference pedal. That is, unlike the first embodiment, the brake pedal 8b is set as a reference pedal, and the position of the accelerator pedal 8a is adjusted in conjunction with the position adjustment of the brake pedal 8b.

  In the example shown in FIG. 23, the operation center shaft 44 of the accelerator pedal 8a is disposed rearward (seat 7 side) and below the operation center shaft 44 of the brake pedal 8b, and both the pedals 8a and 8b are connected to the brake pedal 8b. This is different from the first embodiment in that the position is adjusted around the operation center axis 44. In addition, this example is different from the first embodiment in that the tread surface portion 48a of the accelerator pedal 8a is disposed rearward (seat 7 side) than the tread surface portion 48b of the brake pedal 8b.

  In the example shown in FIG. 23, at the L position, the accelerator pedal 8a is operated along the track L10 and the brake pedal 8b is operated along the track L11. As the seat 7 is adjusted forward, the positions of the pedals 8a and 8b are rotated and adjusted around the rotation adjustment center O1, for example, along with the position adjustment of the pedals 8a and 8b. When the predetermined point A1 of the accelerator pedal 8a also moves to the point A2 along the circular arc track L11 centering on the rotation adjustment center, the predetermined point B1 of the brake pedal 8b moves to the point B2 along the track L11. The amount of movement of the accelerator pedal 8a is set to be smaller than the amount of movement of the brake pedal 8b, thereby reducing the step in the front-rear direction between the accelerator pedal 8a and the brake pedal 8b. The reason why the trajectory at the time of position adjustment is the same between the accelerator pedal 8a and the brake pedal 8b is that the pedals 8a and 8b are on the same arc trajectory. The trajectories do not have to match.

  Then, the pedals 8a and 8b are operated along the tracks L12 and L11 after the position adjustment, and therefore the pedal ratio of the accelerator pedal 8a as a stepping body is slightly changed after the position adjustment (see FIG. 24).

  However, since the amount of movement of the accelerator pedal 8a is set to be small, the change in the pedal ratio can be suppressed as small as possible. Further, as the brake pedal 8b moves closer to the seat 7, that is, when moving backward, the step in the front-rear direction of each pedal 8a, 8b is reduced. The step of the accelerator pedal 8a with respect to the brake pedal 8b can be adjusted in accordance with the size and length of the part, so that the step corresponding to the physique of each occupant can be set to the physique of the occupant seated on the seat 7 Regardless, the operability of the pedals 8a and 8b by the occupant and the feeling of placement on the pedals 8a and 8b can be maintained substantially constant.

  (3) In the first embodiment, the accelerator pedal 8a is adopted as the reference pedal. However, the reference pedal is not limited to the accelerator pedal. For example, as shown in the above (2), the brake pedal 8b is used. There may be a clutch pedal 8c. Further, it is not necessary to use all of the brake pedal 8b, the clutch pedal 8c, and the footrest 51 as the stepping body. For example, only the brake pedal 8b may be used as the stepping body. However, it is preferable that the combination of the reference pedal and the stepped body includes a combination of an accelerator pedal and a brake pedal or a clutch pedal and a footrest, such as a pedal that can be switched by one of the left and right feet of the occupant. That is, according to the present invention, the level difference between the reference pedal and the stepping body is adjusted according to the occupant's physique, so that the reference pedal and the stepping body are switched to either the left or right foot of the occupant. By including a set of pedals and the like, the step change operability is also improved, and the reliability of the pedal operation is improved.

  (4) In the first embodiment, in view of the fact that the position adjustment of the accelerator pedal 8a as the reference pedal is executed according to the position of the seat 7, the brake pedal 8b as the stepping body according to the position of the seat 7 For example, the position adjustment of the reference pedal is executed according to the position of the seat, and the position adjustment of the stepping body is executed based on the position of the reference pedal. Good.

  (5) In the first embodiment, each drive motor 47 is controlled by the position control means 71 so that the accelerator pedal 8a and the other pedals 8b and 8c and the footrest 51 are interlocked. The interlocking means for interlocking the pedal and the stepping body is not limited to the position control means as described above. For example, it is configured as a drive distribution mechanism that distributes the driving force from the drive motor. In order to rotate, a driving force may be transmitted at a predetermined gear ratio to be interlocked. Even if comprised in this way, similarly to the said embodiment, the level | step difference of a reference | standard pedal and a stepping body can be reduced, and a driving posture can be maintained constant irrespective of a passenger | crew's physique.

  (6) In the first embodiment, the accelerator pedal 8a is arranged with its support shaft 44 slightly tilted back and forth with respect to the vehicle width direction, so that the accelerator pedal 8a is close to the seat 7. While the distance between the accelerator pedal 8a and the brake pedal 8b is reduced as it is moved, the step body position adjusting means (such as the pedal position adjusting mechanism 40) for reducing the distance between the pedals is provided. It is not limited to the thing of the said 1st Embodiment.

  For example, as shown in FIG. 25, the support shaft 44 of the accelerator pedal 8a is arranged in parallel to the vehicle width direction, while the guide portion 142b of the pedal position adjusting mechanism 40 is formed in an arc shape centering on the support shaft 44 in a side view. In addition, it is formed so as to be inclined with respect to the longitudinal direction of the vehicle body in plan view so that the rear end portion is located on the brake pedal 8b side. Even if comprised in this way, if the accelerator pedal 8a moves to the seat 7 side, the space | interval with the brake pedal 8b will be reduced, and it will become pedal arrangement according to a passenger | crew's physique.

  Moreover, in the said 1st Embodiment, although the accelerator pedal 8a is comprised so that a movement in the front-back direction and the vehicle width direction of a vehicle body, each pedal, such as this accelerator pedal, is only in the front-back direction of a vehicle body, or a vehicle width direction It may be configured so as to be movable only.

  For example, FIG. 26 shows a specific mechanism when the accelerator pedal is configured to be movable only in the vehicle width direction. That is, a plurality of support brackets 211, 212, and 213 extend from the dash lower panel in the front-rear direction of the vehicle body, and support shafts 214 and 217 are installed between the brackets 211, 212, and 213. A brake pedal and an accelerator pedal are pivotally supported on each of the support shafts 214 and 217, and each pedal is composed of upper half levers 215 and 218 and lower half levers 216 and 219. Each tread part 208b, 208a is attached. Of the support shafts 214 and 217, the support shaft 217 of the accelerator pedal is configured as a feed screw and is screwed at the upper end of the upper half lever 218 of the accelerator pedal, and the accelerator pedal is rotated as the support shaft 217 rotates. Is supposed to move along the vehicle width direction. Then, the ECU 70 controls a motor (not shown) that rotationally drives the support shaft 217 so that the distance between the tread parts 208a and 208b of each pedal decreases as the seat 7 moves forward, that is, toward the pedal 8. It is configured as follows.

  With this configuration, the distance between the pedals is reduced as the seat 7 moves toward the pedal 8, that is, as the physique of the occupant seated on the seat 7 becomes smaller, and the pedal arrangement corresponding to the physique is realized. be able to.

  (7) In the first embodiment, a manual mechanism that adjusts the position by operating the operation handle 13 is employed as the sheet moving mechanism 22. For example, as shown in FIG. 27, a drive motor that rotates the pinion 28 120 may be provided, and the position of the sheet 7 may be adjusted by operating a sheet position adjustment switch 121 that drives the drive motor 120. In this case, when the specific seat position is stored in the storage means 80, the drive motor 120 is driven and controlled so that the position of the seat 7 is automatically adjusted to the specific seat position selected by the occupant according to the occupant's request. The ECU 70 may be configured.

  In the above-described embodiment, a double link mechanism that moves the seat 7 up and down and also moves back and forth is used as the seat moving mechanism 22, but instead of this mechanism or together with this mechanism, along the longitudinal direction of the vehicle body. A seat slide mechanism that slides the seat 7 may be adopted. However, the seat moving mechanism 22 using only the double link mechanism is employed from the viewpoint that the detection of the seat position is easy and the line of sight and the operability of the pedal 8 can be kept constant regardless of the seat position. preferable.

  (8) In the above embodiment, the target position map is corrected when the individually set position is set. However, the correction method of this map is not particularly limited, and there is no correction of the target position map. It may be. For example, when the individual correction position is set, the map correction unit 72 causes the change characteristic line (target position locus) of the pedal 8 and the movable floor panel 9 corresponding to the seat position to be a line passing through the individual setting position. It may be configured to shift the whole.

  (9) Further, the floor position adjusting mechanism 30 and the pedal position adjusting mechanism 40 are not limited to those in the above embodiment, and other mechanisms may be used. For example, a link mechanism or a ratchet mechanism in which links are crossed so as to move the movable floor panel 9 only in the vertical direction may be used as the floor position adjusting mechanism, or any other known lifting mechanism.

  (10) In the first embodiment, mechanical linkages are employed as the pedals 8a, 8b, and 8c. However, electrical linkages such as by-wires may be employed. Even in this case, the steps and intervals between the pedals can be appropriately changed according to the physique of the passenger sitting on the seat 7.
