Description

  The present invention relates to a driving posture adjusting device for an automobile that adjusts the driving posture of a driver seated on a driver's seat, and more particularly to a device that adjusts the arrangement position of a pedal operated by a driver.

Conventionally, as this kind of driving posture adjusting device, there is known a device that detects a driver's physique and adjusts various driving operation systems including a pedal, a floor position, etc. according to the detected physique (for example, Patent Document 1).
Japanese Utility Model Publication No. 63-69655

  In the conventional driving posture adjusting device, the larger the driver's physique is, the farther the position of the driving operation system is from the driver, and the smaller the driver's physique is, the closer the driving operation system is arranged to the driver. In other words, the arrangement position of the driving operation system is adjusted with an adjustment characteristic substantially proportional to the physique of the driver.

  By the way, although a driver includes a man and a woman, there are many cases in which the wrinkle of a woman's footwear is higher than that of a man's footwear. Since the substantial leg length of the driver changes depending on the height of the heel of the footwear, it differs from the leg length relative to the physique. Therefore, focusing on the pedal that is one of the driving operation systems, if the pedal placement position is simply adjusted with an adjustment characteristic approximately proportional to the driver's physique, the pedal placement position is optimized depending on the driver's footwear. If not, it can happen.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a driving posture adjusting device for an automobile capable of optimizing the arrangement position of a pedal with respect to a driver of each physique. There is to do.

  The driving posture adjusting device of the present invention is a driving posture adjusting device for an automobile that adjusts the driving posture of a driver seated in a driver seat.

  The driving posture adjusting device includes a physique detecting unit that detects the physique of the driver, a pedal that the driver steps on, and a pedal adjusting unit that adjusts an arrangement position of the pedal.

  Then, the pedal adjusting means is a first proportional to the physique of the driver so that the smaller the physique, the closer the position of the pedal is to the driver side according to the physique of the driver detected by the physique detecting means. The position of the pedal is adjusted with a second adjustment characteristic different from the first adjustment characteristic when the position of the pedal is adjusted with an adjustment characteristic of 1 and the detected physique is smaller than a predetermined physique. adjust.

  According to this configuration, the pedal adjusting means has the first placement characteristic (operation angle and tread surface) of the pedal according to the driver's physique detected by the physique detecting means, with the first adjustment characteristic substantially proportional to the physique of the driver. Adjust the height. As a result, the smaller the driver's physique, the closer the position of the pedal is to the driver side, and the pedal is arranged at an optimal arrangement position corresponding to the driver's physique.

  The pedal adjustment means adjusts the position of the pedal with a second adjustment characteristic different from the first adjustment characteristic when the physique detected by the physique detection means is smaller than a predetermined physique. That is, when the pedal placement position is adjusted only by the first adjustment characteristic that is substantially proportional to the physique of the driver, the pedal placement position may not be optimized depending on the height of the heel of the footwear. When the size is smaller than the predetermined physique, by adjusting the position of the pedal with the second adjustment characteristic different from the first adjustment characteristic, the height of the heel of the footwear is taken into consideration and the driver of each physique is On the other hand, the position of the pedal is optimized.

  The “predetermined physique” can be, for example, a male physique having a relatively small physique. In this case, a physique smaller than the predetermined physique corresponds to a woman. That is, a driver with a physique smaller than a predetermined physique corresponds to a driver who often wears footwear with high heels.

  Here, the second adjustment characteristic is a characteristic that the position of the pedal approaches the driver side as the physique of the driver is smaller, and the pedal arrangement with respect to a change in the physique as compared with the first adjustment characteristic. It is good also as the characteristic by which the adjustment amount of the position was suppressed.

  In this way, when the detected physique is smaller than the predetermined physique, the pedal adjusting means does not greatly change the pedal arrangement position with respect to the pedal arrangement position corresponding to the predetermined physique. become. Thereby, the placement of the pedal is optimized for a female driver whose substantial leg length is longer than the leg length relative to the physique by wearing high-heeled footwear.

  In addition, since the second adjustment characteristic is a characteristic in which the adjustment amount is suppressed, it is possible to reduce the range in which the pedal can be moved (movable margin), which is advantageous in terms of expanding the cabin space.

  In contrast to this, the second adjustment characteristic may be a characteristic that does not change the position of the pedal with respect to a change in the physique of the driver.

  Thus, when the detected physique is smaller than the predetermined physique, the pedal adjusting means remains in the pedal arrangement position corresponding to the predetermined physique. Thereby, as in the above, the placement of the pedal is optimized for a female driver whose substantial leg length is longer than the leg length relative to the physique by wearing high-heeled footwear. This makes it possible to reduce the travel distance of the pedal, which is advantageous in terms of expansion of the passenger compartment space.

  Furthermore, the second adjustment characteristic may be a characteristic in which the position of the pedal moves away from the driver as the physique of the driver is smaller.

  Thus, when the detected physique is smaller than the predetermined physique, the pedal adjusting means positions the pedal at a position farther from the driver than the pedal arrangement position corresponding to the predetermined physique. Become. Thereby, as in the above, the placement of the pedal is optimized for a female driver whose substantial leg length is longer than the leg length relative to the physique by wearing high-heeled footwear. This makes it possible to reduce the travel distance of the pedal, which is advantageous in terms of expansion of the passenger compartment space.

  The pedal includes a brake pedal and an accelerator pedal, and the pedal adjustment means includes brake pedal adjustment means for adjusting the position of the brake pedal, and accelerator pedal adjustment means for adjusting the position of the accelerator pedal, The brake pedal adjustment means adjusts the position of the brake pedal with the first adjustment characteristic, and the accelerator pedal adjustment means adjusts the position of the accelerator pedal with the first and second adjustment characteristics. It is good.

  In other words, since the accelerator pedal is a pedal that is operated with the heel on the floor, the accelerator pedal adjusting means adjusts the position of the accelerator pedal with the first and second adjustment characteristics. As a result, the position of the accelerator pedal is optimized for each physique driver in consideration of the height of the heel of the footwear as described above.

  On the other hand, since the brake pedal is a pedal that is often stepped on without attaching the heel to the floor, the optimal placement position does not change much even if the heel of the footwear is high or low. In addition, the brake pedal is a pedal that requires a strong pedaling force during sudden braking or the like, while a driver with a smaller physique tends to have a weaker pedaling force. Therefore, the brake pedal adjusting means adjusts the position of the brake pedal with a first adjustment characteristic that is substantially proportional to the physique of the driver. As a result, the smaller the physique, the closer the brake pedal is to the driver side, and the brake pedal is placed in an appropriate position according to the physique of the driver, while ensuring the pedaling force according to the physique of the driver. The

  In this way, by adjusting the adjustment characteristics of the accelerator pedal and the brake pedal, adjustment of the arrangement position according to the function of each pedal is realized.

  By the way, the brake pedal and the accelerator pedal are positioned so that the brake pedal is behind the accelerator pedal (so that the brake pedal is closer to the driver). This is because the brake pedal has a larger stroke amount than the accelerator pedal, so that when the brake pedal located behind is depressed, the difference between the depressed brake pedal position and the accelerator pedal position is reduced. I have to. In this way, for example, when the vehicle is started, the ability to switch from the brake pedal to the accelerator pedal is ensured.

  In addition, by positioning the brake pedal in the rear in advance, for example, in the case of a panic brake, the driver's foot touches the brake pedal first rather than the accelerator pedal, which means that erroneous operation is prevented.

  Under such a premise, the brake pedal adjusting means and the accelerator pedal adjusting means are arranged such that the relative position between the brake pedal and the accelerator pedal approaches the smaller the physique according to the physique of the driver detected by the physique detecting means. Thus, the position of the brake pedal and the position of the accelerator pedal may be adjusted.

  As a result, the smaller the physique of the driver, the closer the relative position of the brake pedal and the accelerator pedal with respect to the vehicle front-rear direction and / or the vehicle width direction becomes. As a result, the amount of movement of the driver's foot is reduced during the stepping operation from the brake pedal to the accelerator pedal and vice versa. In other words, when the driver's foot is small, in other words, when the driver's foot is small, it is possible to change the brake pedal to the accelerator pedal and vice versa with a small amount of movement. Sex is secured.

  The driving posture adjusting device includes a movable floor provided so as to be able to move up and down in the vicinity of the pedal, and a floor adjusting means for adjusting the raising and lowering position of the movable floor according to the physique of the driver detected by the physique detecting means. , May be further provided.

  That is, the pedal adjusting means adjusts the position of the pedal according to the physique of the driver, and adjusts the lift position of the floor by the floor adjusting means, thereby finely adjusting the posture of the driver with respect to the pedal. Is possible. Further, by adjusting the raising / lowering position of the floor, it is also possible to reduce the amount of adjustment of the pedal, which further reduces the movement distance of the pedal, thereby enlarging the passenger compartment space.

  The driver seat includes a seat adjustment unit that adjusts the position of the seat surface, and a seat position detection unit that detects a position of the seat surface adjusted by the seat adjustment unit, and the physique detection unit includes the seat position It may consist of detection means.

  In this way, it is not necessary to separately provide a physique detection means, and after the driver seated in the driver's seat adjusts the position of the seat surface by the seat adjustment means, the physique is detected by the position of the seat surface and the pedal The arrangement position of the pedal by the adjusting means is adjusted. In other words, after the driver adjusts the seating position to adjust the position of the line of sight and the posture with respect to the steering wheel and the seating position of the driver is determined, the driver's driving position is adjusted by adjusting the pedal placement position. The posture can be adjusted accurately.

  The seat adjusting means causes the driver to be in a posture corresponding to the physique and to maintain the posture by adjusting the vehicle front-rear direction position, the vertical position, and the angle in conjunction with the seat surface. While rotating around a predetermined axis in the vehicle width direction, the positions of the eyes of drivers of different physiques are made constant, and the pedal adjusting means is linked to the adjustment of the seating surface by the seat adjusting means. It is good also as adjusting the arrangement | positioning position.

  The seat adjustment means adjusts the seating posture of each driver with different physiques by adjusting the seating surface position in the vehicle front-rear direction and the vertical position and the angle in an interlocked manner, The movement margin with respect to becomes smaller. Also, the pedal adjustment means adjusts the pedal operation angle and the tread height in conjunction with the seat adjustment by the seat adjustment means, so that the angle of the foot relative to the pedal can be adjusted according to the seating posture of the driver being rotated. It is optimized.

  As described above, according to the vehicle driving posture adjusting apparatus of the present invention, the physique of the driver is adjusted by adjusting the position of the pedal with the first adjustment characteristic substantially proportional to the physique of the driver according to the physique of the driver. When the pedal is arranged at an optimal arrangement position according to the driver and the physique of the driver is smaller than a predetermined physique, the position of the pedal is adjusted with a second adjustment characteristic different from the first adjustment characteristic. By adjusting, it becomes possible to set the position of the pedal in consideration of the height of the heel of the footwear of the driver, and the position of the pedal can be optimized for the driver of each physique. .

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows the overall configuration of an automobile driving posture adjusting apparatus 1 according to the present embodiment. The driving posture adjusting device 1 is a device that adjusts the driving posture of a driver seated on a driver seat on which a steering wheel 2 is disposed, and a seat adjusting means 4 that adjusts the position of a seat 31 provided on the driver seat. The floor adjusting means 5 for adjusting the raising / lowering position of the movable floor 51 in the vicinity of the pedal, the accelerator pedal adjusting means 7 for adjusting the arrangement position of the accelerator pedal 71, and the brake pedal adjusting means 8 for adjusting the arrangement position of the brake pedal 81 And including.

  A slide mechanism 40 is disposed on an under floor 91 corresponding to the driver seat. As shown in FIG. 2, the slide mechanism 40 includes a lower rail 41 fixed to the under floor 91 and an upper rail 42 slidable in the vehicle front-rear direction (hereinafter simply referred to as the front-rear direction) with respect to the lower rail 41. . The upper rail 42 is fixed in position with respect to the lower rail 41 in a normal state.

  The seat adjusting means 4 is disposed between the upper rail 42 and a seat frame 32 to which a seat cushion of the seat 31 is fixed. The seat adjusting means 4 is provided on the seat surface of the seat 31. The front-rear direction position, the vertical direction position, and the angle are adjusted in conjunction with each other.

  Specifically, the seat adjusting means 4 includes a front link 44 and a rear link 45 that are pin-coupled to a support bracket 43 that is attached to the upper rail 42. Of these two links 44, 45, the front link 44 is pin-coupled to the front end position of the seat frame 32, while the rear link 45 is pin-coupled to the rear end position of the seat frame 32.

  The front link 44 has a longer link length than the rear link 45, and the rear link 45 has a slit 45a extending in the longitudinal direction thereof.

  The seat adjusting means 4 is also provided with a gear box 46 that is located at an intermediate position between the front link 44 and the rear link 45 and is attached to the upper rail 42.

  The gear box 46 is provided with an operation lever 47, a ratchet 47a attached to the operation lever 47 so as to rotate integrally, a gear 47b that engages and rotates with the ratchet 47a, and a gear 47b that is integrated with the gear 47b. A pinion (or worm) 47c, and a rack member 48 that meshes with the pinion 47c.

  The operation lever 47 is a lever that is manually operated by a driver, and is attached to the gear box 46 so as to be rotatable around a predetermined rotation axis extending in the vehicle width direction. The gear 47b and the pinion 47c are attached to the gear box 46 so as to be rotatable around another rotation axis parallel to the rotation axis of the operation lever 47 (and the ratchet 47a).

  The rack member 48 is disposed so as to extend in the front-rear direction, and a substantially intermediate portion thereof meshes with the pinion 47 c, and the rear end portion of the rack member 48 is in contact with the slit 45 a of the rear link 45. They are connected by a slide pin 48a.

  As a result, when the driver rotates the operation lever 47, the rack member 48 moves in the front-rear direction via the ratchet 47a, the gear 47b, and the pinion 47c, and is coupled via the slide pin 48a. The rear link 45 undulates. Then, the seat frame 32, and hence the seat surface of the seat 31, is changed in position by the front link 44 and the rear link 45. At this time, the front link 44 and the rear side are changed. When the link lengths with the link 45 are different from each other, the seat surface is changed in conjunction with the front-rear direction position, the vertical direction position, and the angle. Specifically, the more the seat surface moves forward, the higher the seat surface and the smaller the angle of the seat surface with respect to the horizontal (see the two-dot chain line in FIG. 2), and the lower the seat surface moves backward. In addition, the angle of the seating surface with respect to the horizontal increases (see the one-dot chain line in FIG. 2). Here, a position a1 shown in FIG. 1 corresponds to a sitting state of a driver having a large physique, a position b1 corresponds to a sitting state of a driver having a physique (a relatively small physique), and a position c1 is a predetermined position. It corresponds to the sitting state of a driver (female) who is smaller than the physique.

  Unlike the case where the front / rear direction position of the seat surface is simply changed by interlockingly changing the front / rear direction position, the vertical direction position, and the angle of the seat surface, the driving posture (mode) is changed for each physique. ) Can be different. That is, as shown in FIG. 3, the drivers M1 and M2 having large physique (male drivers with relatively large physique) are in a posture in which the knee bends (so-called driving posture in an RV vehicle (RV mode), see FIG. 4) The small physique drivers M3 and F3 (a male relatively small physique driver and a female relatively small physique driver) are in a posture in which the knees are stretched (so-called sedan driving posture (sedan mode), see FIG. 4). Further, as shown in FIG. 4, the adjustment of the seating surface may be performed by setting a driver in a mode posture corresponding to the physique to a predetermined vehicle width direction axis (for example, the swing center of the accelerator pedal 71). ) (See P1 and P1 ′ in FIG. 4). By combining this mode and rotation, as shown in FIG. 3, the positions of the lines of sight E of the drivers M1, M2, M3, and F having different physiques can be made the same.

  By adjusting the driving posture, not only the driving posture of each driver having a different physique is optimized, but also a driver with a large physique is in a posture in which the knee bends, and a driver with a small physique is in a posture in which the knee is extended. There is also an advantage that the movable range (moving margin) with respect to the direction can be reduced (see L1 in FIG. 4).

  As shown in FIG. 1, the seat 31 is provided with a seat position detection sensor 49, and the position of the seat 31 (seat surface) is detected by the sensor 49.

  The floor located in the vicinity of the pedals 71 and 81 is a movable floor 51 whose raising / lowering position is adjusted by the floor adjusting means 5, and the movable floor 51 is arranged in the front-rear direction as shown in FIGS. The front floor 51a and the rear floor 51b arranged side by side are configured to be hinged to each other. The front floor 51a is pivotally supported around a pivot extending in the vehicle width direction with respect to the under floor 91, while the rear end of the rear floor 51b is disposed so as to cover a base plate 52 described later. It is placed on the upper surface of the upper floor 92 and slides on the upper surface of the upper floor 92 as the movable floor 51 moves up and down, as will be described later.

  The floor adjusting means 5 is disposed between the fixed under floor 91 and the movable floor 51. The floor adjusting means 5 is attached to the upper surface of the under floor 91 and extends in the vehicle width direction at the driver's seat, two link rods 53 (only one is shown in FIG. 5) extending in the front-rear direction, Two swing arms 54 (only one is shown in FIG. 5) pin-coupled to the front ends of the two link rods 53, and two motor links pin-coupled to the rear ends of the two link rods 53, respectively. 55 (only one is shown in FIG. 5). A floor motor 56 is disposed at a substantially central position in the vehicle width direction on the upper surface of the base plate 52, and output shafts 56a of the floor motor 56 extend outward on both sides in the vehicle width direction.

  As shown in FIG. 6, the two link rods 53 are disposed on both sides of the base plate 52 in the vehicle width direction.

  As shown in FIG. 5, one end of each motor link 55 is pin-coupled to the rear end of the link rod 53, while the other end is connected to the output shaft 56 a of the floor motor 56. Has been.

  Each of the swing arms 54 is formed in a substantially L shape in a side view, and a bent portion of the L shape swing arm 54 is provided on the upper surface of the front end of the base plate 52 so as to extend in the vehicle width direction. It is connected to the shaft 54a. One end of the swing arm 54 sandwiched between the bent portions is pin-coupled to the front end of the link rod 53, while the other end of the swing arm 54 sandwiched between the bent portions A roller 57 extending in the vehicle width direction is rotatably attached. The rollers 57 are disposed so as to connect the two swing arms 54 disposed on both outer sides of the base plate 52 in the vehicle width direction, and the movable floor 51 (the front floor 51a). It is in contact with the lower surface.

  As a result, when the floor motor 56 is driven, the link rod 53 moves in the front-rear direction via the motor link 55, whereby the swing arm 54 rotates about the rotation support shaft 54a. Thus, the vertical position of the roller 57 attached to the swing arm 54 is changed, and the raising / lowering position of the movable floor 51 in contact with the roller 57 is changed. That is, when the floor motor 56 is driven so that the link rod 53 moves backward, the swing arm 54 rotates counterclockwise, and the roller 57 moves upward. As a result, the front floor 51a rotates upward about the pivot axis in the counterclockwise direction, and the rear floor 51b rotates clockwise accordingly. Then, the movable floor 51 rises. On the other hand, when the floor motor 56 is driven so that the link rod 53 moves forward, the swing arm 54 rotates clockwise and the roller 57 moves downward. As a result, the front floor 51a is rotated clockwise around the pivot, and the rear floor 51b is rotated counterclockwise. Then, the movable floor 51 is lowered. As described above, the angle of the movable floor 51 is also changed with the change of the lift position.

  The accelerator pedal adjusting means 7 and the brake pedal adjusting means 8 simultaneously adjust the operation angle and the tread height of the accelerator pedal 71 and the brake pedal. Since the configuration of the accelerator pedal adjusting means 7 and the configuration of the brake pedal adjusting means 8 are the same, the configuration of the accelerator pedal adjusting means 7 will be described below with reference to FIGS. The description of the configuration is omitted.

  As shown in FIGS. 7 and 8, the accelerator pedal adjusting means 7 includes a bracket 72 attached to a dash panel 93 (see FIG. 1). The bracket 72 is provided with a support shaft 73 that extends substantially in the vehicle width direction and forms the rotation center of the accelerator pedal 71, and the upper end portion of the pedal bracket upper 74 is pivotally supported by the support shaft 73. ing.

  A guide member 75 having a guide groove 75a formed in an arc shape centering on the support shaft 73 is integrally provided at a lower end portion of the pedal bracket upper 74, and the guide groove 75a has an arc shape. A slider 76 that is movable along the guide groove 75a is disposed inside the guide groove 75a. Thus, the slider 76 is integrally provided with an upper end portion of a pedal bracket lower 77 having an accelerator pedal 71 attached to the lower end portion thereof. A rack portion 76a is formed on the side surface of the slider 76, and a worm gear 78a is always meshed with the rack portion 76a. The worm gear 78 a is connected to a flexible wire 78 connected to the output shaft of the accelerator pedal motor 79, and the worm gear 78 a is rotated by the motor 79 via the flexible wire 78.

  Thus, when the accelerator pedal motor 79 is driven, the worm gear 78a rotates via the flexible wire 78, and the slider 76 in which the rack portion 76a meshes with the worm gear 78a moves in the front-rear direction along the guide groove 75a. Move to. As the slider 76 moves, the accelerator pedal 71 rotates about the support shaft 73 via the pedal bracket lower 77, and both the operation angle of the accelerator pedal 71 and the tread height are adjusted. become.

  As described above, the configuration of the accelerator pedal adjusting means 7 and the configuration of the brake pedal adjusting means 8 are both the same. As shown in FIG. 6, the brake pedal adjusting means 8 is separate from the accelerator pedal adjusting means 7. A brake pedal motor 89 is provided. The brake pedal 81 is an ambassador even though the movement direction DB is substantially aligned with the front-rear direction. The accelerator pedal 71 has an outward movement direction DA that is forward in the vehicle width direction. The rear side is inclined with respect to the front-rear direction so as to be inward in the vehicle width direction (direction approaching the brake pedal 81).

  The driving posture adjusting apparatus 1 further includes an ECU 94 that controls the driving of the floor motor 56, the accelerator pedal motor 79, and the brake pedal motor 89. The ECU 94 receives the detection signal of the seat position detection sensor 49, and controls the three motors of the floor motor 56, the accelerator pedal motor 79, and the brake pedal motor 89 with preset adjustment characteristics. Do. That is, since the seat position detected by the seat position detection sensor 49 corresponds to the physique of the driver, the ECU 94 determines whether the movable floor 51 is raised or lowered, the accelerator pedal 71 is disposed, according to the physique of the driver. And the arrangement position of the brake pedal 81 is adjusted optimally. As described above, in the driving posture adjusting device 1, the floor adjusting means 5 adjusts the raising / lowering position of the movable floor 51 in conjunction with the seat adjustment by the seat adjusting means 4, and the accelerator and brake pedal adjusting means 7, 8 The arrangement positions of the accelerator and brake pedals 71 and 81 are adjusted.

  Next, adjustment control between the position where the accelerator and brake pedals 71 and 81 are arranged by the ECU 94 and the position where the movable floor 51 is raised and lowered will be described.

  The ECU 94 has three maps as adjustment characteristics set in advance for adjusting the movable floor 51, the accelerator pedal 71 and the brake pedal 81. Specifically, as shown in FIG. 9, the ECU 94 has a seat-floor map (FIG. 9A) in which the raising / lowering position of the movable floor 51 with respect to the seat position is set, and the disposition position of the accelerator pedal 71 with respect to the seat position. There are three maps: a set seat-accelerator pedal map (FIG. 9 (b)) and a seat-brake pedal map (FIG. 9 (c)) in which the position of the brake pedal 81 relative to the seat position is set. Based on these maps, the elevation position of the movable floor 51, the arrangement position of the accelerator pedal 71, and the arrangement position of the brake pedal 81 are adjusted.

  The seat-floor map is basically set so that the ascending / descending position of the movable floor 51 is substantially proportional to the seat position (first adjustment characteristic). Thereby, the ECU 94 controls the floor motor 56 so that the movable floor 51 rises as the seat position is the front position, in other words, as the driver's physique is smaller. However, the seat-floor map is different from the first adjustment characteristic when the seat position is ahead of a predetermined seat position, specifically, the seat position (M3) corresponding to a relatively small physique male. 2 adjustment characteristics are set. The second adjustment characteristic is a characteristic that the movable floor 51 rises as the seat position is the front position, and the lift position of the movable floor 51 with respect to the change in the seat position as compared with the first adjustment characteristic. This is a characteristic in which the adjustment amount is suppressed (hereinafter, this characteristic is referred to as a suppression type).

  The seat-accelerator pedal map is also basically set so that the position where the accelerator pedal 71 is disposed is substantially proportional to the seat position (first adjustment characteristic). Thereby, the ECU 94 controls the accelerator pedal motor 79 so that the accelerator pedal 71 approaches the driver as the seat position is the front position, in other words, as the driver's physique is smaller. However, the seat-accelerator pedal map is set to a second adjustment characteristic different from the first adjustment characteristic when the seat position is ahead of the predetermined seat position (M3). The second adjustment characteristic is a characteristic in which the accelerator pedal 71 is separated from the driver as the seat position is the front position (hereinafter, this characteristic is referred to as an inverted type).

  Further, the seat-brake pedal map is basically set so that the disposition position of the brake pedal 81 is substantially proportional to the seat position (first adjustment characteristic). Thereby, the ECU 94 controls the brake pedal motor 89 so that the brake pedal 81 approaches the driver as the driver's physique is smaller. However, the seat-brake pedal map is also set to a second adjustment characteristic different from the first adjustment characteristic when the seat position is ahead of the predetermined seat position (M3). This second adjustment characteristic is an inversion type characteristic like the seat-accelerator pedal map.

  Accordingly, when the driver sits on the seat and operates the operation lever 47 to set the position of the seat surface, and the seat position detection sensor 49 detects the seat position, the ECU 94 receives the detection signal. A necessary motor control amount is calculated by referring to the above-described seat-floor map, seat-accelerator pedal map, and seat-brake pedal map. Thus, the ECU 94 controls the floor motor 56, the accelerator pedal motor 79, and the brake pedal motor 89 with the calculated motor control amounts. Accordingly, as shown in FIG. 1, when the seat position is the position a1, in other words, when the driver's physique is large (M1's physique), the movable floor 51 is positioned at the position a2 which is the lower position. Both the accelerator pedal 71 and the brake pedal 81 are located at a position a3 that is a forward position (a position away from the driver). When the seat position is the position b1, in other words, when the driver's physique is a predetermined physique (M3's physique), the movable floor 51 is located at the upper position b2, while the accelerator pedal 71 and the brake pedal 81 is located at a position b3 which is a rear position (position close to the driver). When the seat position is the position c1, in other words, when the driver's physique is smaller than the predetermined physique (F3's physique), the movable floor 51 is further positioned at the position c2 which is the upper position, while the accelerator pedal. 71 and the brake pedal 81 are both located at a position c3 which is a middle position.

  As described above, when the driver is a physique smaller than the predetermined physique, generally a female driver, the accelerator pedal 71 and the brake pedal 81 are farther from the driver than the male driver (M3) having a relatively small physique. Placed in position. As a result, the female driver has a high probability of wearing high-heeled footwear, in which case the substantial leg length is longer than the leg length corresponding to the physique, but even in that case, as shown in FIG. In addition, the arrangement positions of the accelerator pedal 71 and the brake pedal 81 can be set to optimum positions.

  Further, as shown in FIG. 6, the moving direction of the accelerator pedal 71 is inclined with respect to the front-rear direction, so that the accelerator pedal 71 is positioned rearward with respect to the vehicle width direction of the accelerator pedal 71 and the brake pedal 81. The interval is narrowed. Therefore, the smaller the physique of the driver, the narrower the distance between the accelerator pedal 71 and the brake pedal 81 with respect to the vehicle width direction, and the driver with a small foot steps from the brake pedal 81 to the accelerator pedal 71 or vice versa with a small amount of movement. It is possible to change the pedal and the pedal changeability is improved.

  Further, the second adjustment characteristic relating to the accelerator pedal 71 and the brake pedal 81 is an inverted characteristic, that is, a characteristic in which the adjustment direction is opposite to the first adjustment characteristic. This makes it possible to reduce the travel distance of the vehicle, which is advantageous in terms of expanding the cabin space.

  Similarly, since the second adjustment characteristic related to the movable floor 51 is a characteristic (inhibition type) in which the adjustment amount is suppressed, it is possible to reduce the up-and-down margin of the movable floor 51, and in terms of expanding the cabin space. Become advantageous.

  Then, by adjusting the driving posture by linking the accelerator pedal 71, the brake pedal 81, and the movable floor 51, the posture of the driver with respect to the pedal can be adjusted more finely. Compared with the case where the floor 51 is adjusted independently, the adjustment amount of each of the pedals 71 and 81 and the movable floor 51 can be reduced, and the respective adjustment margins can be further reduced to further expand the passenger compartment space. Is planned.

  Further, the ECU 94 adjusts the positions of the pedals 71 and 81 and the movable floor 51 in accordance with the detection result of the seat position detection sensor 49, so that the driver sets the position of the seating surface and determines the seating position of the driver. Then, the positions of the pedals 71 and 81 and the movable floor 51 are adjusted. That is, the driver's driving posture can be accurately adjusted by performing the respective adjustments in the order of adjusting the seat position and adjusting the positions of the pedals 71 and 81 and the movable floor 51.

  In particular, the seat adjusting means 4 rotates the driver in a mode corresponding to the physique around a predetermined axis in the vehicle width direction, whereas the accelerator and brake pedal adjusting means 7 and 8 are provided with the accelerator pedal 71 and the brake. While adjusting the pedal operating angle, the floor adjusting means 5 adjusts the raising and lowering position and angle of the movable floor 51, whereby the angle of the foot with respect to the pedal is optimized according to the seating posture of the driver.

(Modification of adjustment characteristics of each pedal and movable floor)
The adjustment characteristics (second adjustment characteristics) of the pedals 71 and 81 and the movable floor 51 are not limited to the characteristics shown in FIG. Hereinafter, modifications of the adjustment characteristics of the pedals 71 and 81 and the movable floor 51 will be described.

(Modification 1)
The second adjustment characteristic relating to the movable floor 51 may be an inversion type characteristic. That is, as shown in FIG. 11A, the seat-floor map is basically set so that the ascending / descending position of the movable floor 51 is substantially proportional to the seat position (first adjustment characteristic). On the other hand, when the seat position is in front of the predetermined seat position (M3), the floor is set so that the floor is positioned lower as the seat position is forward (second adjustment characteristic). Thus, the ECU 94 controls the floor motor 56 so that the movable floor 51 rises as the seat position is the front position, in other words, as the driver's physique is smaller, and the seat position is the predetermined seat position (M3). ), The movable floor 51 is lowered as the seat position is the front position.

  Further, the second adjustment characteristics of the accelerator pedal 71 and the brake pedal 81 may be suppression characteristics. That is, as shown in FIGS. 11B and 11C, the seat-accelerator pedal map and the seat-brake pedal map are basically proportional to the seat positions of the accelerator and brake pedals 71 and 81. (First adjustment characteristic) On the other hand, when the seat position is ahead of the predetermined seat position (M3), the accelerator and brake pedals 71 and 81 are more as the seat position is forward. The position is set so that the position approaches the driver side, and the adjustment amount with respect to the change in the physique is suppressed compared to the first adjustment characteristic (second adjustment characteristic). Thus, the ECU 94 controls the accelerator and brake pedal motors 79 and 89 so that the accelerator and brake pedals 71 and 81 are closer to the driver as the seat position is the front position, in other words, as the driver's physique is smaller. At the same time, when the seat position is ahead of the predetermined seat position (M3), the accelerator and brake pedals 71 and 81 are not moved so much.

  As a result, as shown in FIG. 12, when the seat position is the position a1, in other words, when the driver's physique is large (M1's physique), the movable floor 51 is positioned at the position a4 which is the lower position. Both the accelerator pedal 71 and the brake pedal 81 are located at a position a5 that is a forward position (a position away from the driver). When the seat position is the position b1, in other words, when the driver's physique is a predetermined physique (M3's physique), the movable floor 51 is located at the upper position b4, while the accelerator pedal 71 and the brake pedal 81 is located at the position b5 which is the middle position. When the seat position is the position c1, in other words, when the driver's physique is smaller than the predetermined physique (F3's physique), the movable floor 51 is located at the middle position c4, while the accelerator pedal 71 Both the brake pedal 81 and the brake pedal 81 are located at a position c5 which is a rear position (position close to the driver).

  Even in this case, the arrangement position of the accelerator pedal 71 and the brake pedal 81 can be set to an optimal position for a female driver wearing footwear with high heels.

(Modification 2)
As shown in FIG. 13A, the second adjustment characteristic related to the raising / lowering position of the movable floor 51 is a characteristic that does not change the raising / lowering position of the movable floor with respect to the change of the seat position (hereinafter, this characteristic is prohibited). Similarly, the second adjustment characteristic related to the positions where the accelerator pedal 71 and the brake pedal 81 are arranged is also different from the change in the seat position as shown in FIGS. For example, it may be a prohibited type characteristic in which the arrangement positions of the pedals 71 and 81 are not changed.

(Modification 3)
The accelerator and brake pedals 71 and 81 and the movable floor 51 are adjusted with a quadratic function adjustment characteristic with respect to the seat position by electrically controlling the motors 56, 79 and 89 by the ECU 94, respectively. . On the other hand, as shown in FIG. 14, for example, the adjustment characteristics of the pedals 71 and 81 and the movable floor 51 may be set in a linear function with respect to the seat position. Specifically, FIG. 14 (a) shows an example of a suppression type characteristic that suppresses the adjustment amount when it is smaller than a predetermined physique, and FIG. 14 (b) shows the control direction when it is smaller than the predetermined physique. An example of an inversion type characteristic to be inverted is shown, and FIG. 5C shows an example of an inhibition type characteristic in which control is prohibited when it is smaller than a predetermined physique.

  By adopting such adjustment characteristics, for example, mechanical control using a gear or the like is possible, and the system mechanism can be simplified.

  Note that the quadratic function control shown in FIGS. 9, 11, and 13 may be combined with the linear function control shown in FIG. For example, the accelerator pedal 71 may be controlled by a linear function while the brake pedal 81 may be controlled by a quadratic function, or vice versa. Moreover, while the movable floor 51 is controlled by a quadratic function, the pedals 71 and 81 may be controlled by a linear function, or vice versa.

(Combination of floor adjustment characteristics and pedal adjustment characteristics)
Next, a combination of the adjustment characteristics of the movable floor 51 and the adjustment characteristics of the pedals 71 and 81 will be described.

  For example, for the suppression type floor adjustment characteristic shown in FIG. 9A, for example, the inversion type shown in FIGS. 9B, 11C, 11B, 13C, 13B, 13C. It is possible to combine the pedal adjustment of either the inhibition type or the inhibition type.

  Further, for example, for the inversion type floor adjustment characteristic shown in FIG. 11A, for example, the suppression type or prohibition type pedal adjustment shown in FIGS. 11B, 11C, 13B, 13C is performed. It is possible to combine them.

  Further, for example, for the prohibited type floor adjustment characteristic shown in FIG. 13 (a), it is shown in FIG. 9 (b) (c), FIG. 11 (b) (c) or FIG. 13 (b) (c), for example. It is possible to combine any of the pedal adjustments of the reverse type, the suppression type, and the prohibition type.

(Combination of accelerator pedal adjustment characteristics and brake pedal adjustment characteristics)
Next, a combination of the adjustment characteristic of the accelerator pedal 71 and the adjustment characteristic of the brake pedal 81 will be described.

  First, as shown in FIG. 15, the adjustment characteristic of the accelerator pedal 71 and the adjustment characteristic of the brake pedal 81 are the same type. When the suppression type is adopted as the adjustment characteristic of the accelerator pedal 71, When the adjustment characteristic is the same suppression type, when the prohibition type is adopted as the adjustment characteristic of the accelerator pedal 71, the adjustment characteristic of the brake pedal 81 is also the same inhibition type, and when the reverse type is adopted as the adjustment characteristic of the accelerator pedal 71, the brake pedal The adjustment characteristics 81 may be the same inversion type.

  There is an advantage that control is facilitated by making the adjustment characteristics of the two pedals 71 and 81 the same type. In addition, although the space | interval with respect to the front-back direction of the accelerator pedal 71 and the brake pedal 81 does not change, as shown in FIG. 6, the space | interval with respect to the vehicle width direction changes by inclining the moving direction of the accelerator pedal 71 with respect to the front-back direction. .

  On the other hand, as shown in FIG. 16, the adjustment characteristics of the two pedals 71 and 81 are set such that the smaller the driver's physique, the smaller the distance (step) between the accelerator pedal 71 and the brake pedal 81 in the front-rear direction. It may be different. That is, when the suppression type is adopted as the adjustment characteristic of the accelerator pedal 71, the inversion type or the inhibition type is adopted as the adjustment characteristic of the brake pedal 81, and when the inhibition type is adopted as the adjustment characteristic of the accelerator pedal 71, the brake pedal 81 is adopted. The adjustment characteristic may be an inversion type.

  By such a combination of the adjustment characteristics of the accelerator pedal 71 and the adjustment characteristics of the brake pedal 81, the smaller the driver's physique, the smaller the distance (step) between the accelerator pedal 71 and the brake pedal 81 in the front-rear direction. Further, as described above, the distance (step) between the accelerator pedal 71 and the brake pedal 81 in the vehicle width direction is also reduced. As a result, when a driver with a small physique, that is, a driver with a relatively small foot, switches between the two pedals 71 and 81, the amount of movement of the foot is reduced, and the pedal switching performance is improved.

  In addition, as shown in FIG. 17, when the suppression type, the prohibition type, or the reverse type is adopted as the adjustment characteristic of the accelerator pedal 71, the suppression type may be adopted as the adjustment characteristic of the brake pedal 81.

  That is, for the brake pedal 81, only the suppression type may be employed, and the prohibition type or the inversion type may not be employed. This is because the accelerator pedal 71 is a pedal that is stepped on while the heel is attached to the floor, and therefore the optimal position of the accelerator pedal 71 is greatly affected by the height of the heel of the footwear. Therefore, by adopting a suppression type, a prohibition type, or an inversion type as the adjustment characteristic of the accelerator pedal 71, adjustment of the position of the accelerator pedal 71 in consideration of the height of the driver's footwear is realized.

  On the other hand, since the brake pedal 81 is a pedal that is often stepped on without attaching the heel to the floor, the optimal arrangement position of the brake pedal 81 is not greatly affected by the height of the heel of the footwear. . In addition, the brake pedal 81 is a pedal that requires a strong pedaling force during sudden braking or the like, while a driver with a smaller physique tends to have a weaker pedaling force. Therefore, as the adjustment characteristic of the brake pedal 81, it is desirable to adopt a suppression type adjustment characteristic in which the brake pedal 81 always approaches the driver side as the driver's physique is smaller. By doing so, it is possible to ensure the stepping force according to the physique of the driver while making the arrangement position of the brake pedal 81 appropriate according to the physique.

  The adjustment of the brake pedal 81 may be performed using only the first adjustment characteristic, without using the first adjustment characteristic and the second adjustment characteristic different from the first adjustment characteristic. In this case as well, as described above, it is possible to ensure the stepping force according to the physique of the driver while making the arrangement position of the brake pedal 81 appropriate according to the physique.

(Other embodiments)
In the above-described embodiment, the sheet adjusting unit 4 is configured by unequal length double links, but the configuration of the sheet adjusting unit 4 is not limited to this. Further, unlike the seat adjusting means 4, the seat surface of the seat 31 may not be adjusted in conjunction with the front-rear direction position, the up-down direction position, and the angle, but only the front-rear direction position is adjusted. There may be.

  Further, the physique of the driver is detected by detecting the seat position by the seat position detecting sensor 49, but the physique of the driver can also be detected by another means. For example, it is possible to detect the physique of the driver by imaging the driver with a camera or the like.

  Furthermore, in the above embodiment, the adjustment of the pedals 71 and 81 and the adjustment of the movable floor 51 are performed in conjunction with each other. However, only the positions where the pedals 71 and 81 are arranged are adjusted according to the physique of the driver. May be. That is, the floor near the pedal may not be the movable floor 51 that can be raised and lowered.

  As described above, the present invention adjusts the position of the pedal not with a single adjustment characteristic but with two different adjustment characteristics. Therefore, the position of the pedal is considered in consideration of the height of the driver's foot. This is useful in that the driving posture of the driver seated on the driver's seat can be adjusted more appropriately.
