Description

本発明は、倒立二輪台車に関する。   The present invention relates to an inverted motorcycle.

踏板に揺動を与えることで、ユーザの足関節に運動を与えて、訓練を行う足関節運動装置がある。特許文献1では、ユーザの踵側とつま先側との荷重を検知するセンサを有する踏板(ペダル部)を備える足関節運動装置が開示されている。この足関節運動装置では、ユーザの異常を検知して訓練を停止することができる。また、上記した訓練は、この足関節運動装置と同様の構成を含む倒立二輪台車を用いて実施し得る。   2. Description of the Related Art There is an ankle exercise apparatus that exercises by giving a motion to a user's ankle joint by swinging a tread. Patent Document 1 discloses an ankle joint exercise device including a tread (pedal part) having a sensor that detects a load on a user's heel side and toe side. In this ankle joint exercise device, training can be stopped by detecting a user's abnormality. Further, the above-described training can be performed using an inverted two-wheeled carriage including a configuration similar to that of the ankle joint exercise device.

特開2008−061964号公報JP 2008-061964 A

ところで、硬縮した足を有する患者が、特許文献1で開示される足関節運動装置を用いて上記した訓練を行うと、足裏全体を踏板に載せることができないことがある。センサによる荷重の検出に基づいて、足の硬縮の回復度合いを判定することが考えられる。しかし、足裏の外側部分、又は、内側部分を踏板に載せている状態と、足裏全体を踏板に載せている状態とを判別しにくい。そのため、足の硬縮の回復度合いの判定精度に改善の余地が有った。   By the way, when a patient having a rigid foot performs the above-described training using the ankle joint exercise device disclosed in Patent Document 1, the entire sole may not be placed on the tread. It is conceivable to determine the degree of recovery of foot stiffness based on detection of a load by a sensor. However, it is difficult to discriminate between a state where the outer or inner part of the sole is placed on the tread and a state where the entire sole is placed on the tread. Therefore, there is room for improvement in the determination accuracy of the degree of recovery of leg stiffness.

本発明は、足の硬縮の回復度合いの判定を誤るおそれが小さい倒立二輪台車を提供するものである。   The present invention provides an inverted two-wheeled carriage with a low risk of erroneous determination of the degree of recovery of leg stiffness.

The inverted two-wheel carriage 100 can also be used as a center-of-gravity swing training device that trains a passenger to swing the center of gravity. This passenger may have, for example, stiff legs.

本体1は、車輪4R、4Lの駆動を制御する制御部9(図7参照)と、車輪4R、4Lを駆動させるモータ10(図7参照)とを含む。制御部9は、電源(図示略)に接続されており、必要に応じて、電流を供給される。制御部9は、例えば、CPU(Central Processing Unit)を有する演算回路と、プログラムメモリやデータメモリその他のRAM(Random Access Memory)やROM(Read Only Memory)等を有する記憶装置等を備えている。制御部9は、倒立二輪台車100を重心揺動訓練装置としても使用できるように、制御するためのプログラムメモリやデータメモリを備える。また、必要に応じて、制御部9は、倒立二輪台車100が倒立状態となるように、制御するためのプログラムメモリやデータメモリを備える。   The main body 1 includes a control unit 9 (see FIG. 7) that controls driving of the wheels 4R and 4L, and a motor 10 (see FIG. 7) that drives the wheels 4R and 4L. The controller 9 is connected to a power source (not shown), and is supplied with current as necessary. The control unit 9 includes, for example, an arithmetic circuit having a CPU (Central Processing Unit), a storage device having a program memory, a data memory, other RAM (Random Access Memory), a ROM (Read Only Memory), and the like. The control unit 9 includes a program memory and a data memory for controlling so that the inverted two-wheeled carriage 100 can be used as a center of gravity swing training apparatus. Moreover, the control part 9 is provided with the program memory and data memory for controlling so that the inverted two-wheeled carriage 100 may be in an inverted state as needed.

搭乗台2R、2Lは、本体1の両側にそれぞれ設置されており、車輪4R、4Lは、それぞれ、搭乗台2R、2Lの下方(ここでは、−Z方向)に回転可能に設置されている。本体1は、踏板3R、3Lをそれぞれ回動可能に支持する。荷重圧センサ群7(図7参照)と、姿勢角センサ群8(図7参照)とが踏板3R、3Lに設けられる。踏板3R、3Lは、搭乗者の足を載せる板である。荷重圧センサ群7は、踏板3R、3Lにかかる荷重圧を検出し、姿勢角センサ群8は、踏板3R、3Lの姿勢角を検出する。   The boarding bases 2R and 2L are respectively installed on both sides of the main body 1, and the wheels 4R and 4L are rotatably installed below the boarding bases 2R and 2L (here, in the −Z direction). The main body 1 supports the treads 3R and 3L so as to be rotatable. A load pressure sensor group 7 (see FIG. 7) and a posture angle sensor group 8 (see FIG. 7) are provided on the treads 3R and 3L. The treads 3R and 3L are plates on which the passenger's feet are placed. The load pressure sensor group 7 detects the load pressure applied to the treads 3R, 3L, and the attitude angle sensor group 8 detects the attitude angle of the treads 3R, 3L.

踏板3Rの一例について説明する。図2に示すように、踏板3Rは、踵部31と、親指側部32と、小指側部33とを含む。踵部31は、倒立二輪台車100の後側に配置され、親指側部32と小指側部33とは、踵部31の前方(ここでは、−X方向)に配置される。小指側部33は親指側部32よりも右側(ここでは、Y方向)に配置される。搭乗者の足f0の足裏全体が踏板3Rに載ったとき、踵部31は足f0の踵部を載せ、親指側部32は足f0の親指側部分を載せ、小指側部33は足f0の小指側部分を載せることとなる。踵部31と、親指側部32と、小指側部33とは、一枚の板を分割することで形成してもよい。   An example of the tread board 3R will be described. As shown in FIG. 2, the tread plate 3 </ b> R includes a collar portion 31, a thumb side portion 32, and a little finger side portion 33. The collar part 31 is disposed on the rear side of the inverted two-wheeled carriage 100, and the thumb side part 32 and the little finger side part 33 are disposed in front of the collar part 31 (here, in the −X direction). The little finger side portion 33 is arranged on the right side (here, the Y direction) than the thumb side portion 32. When the entire sole of the passenger's foot f0 is placed on the tread 3R, the heel part 31 places the heel part of the foot f0, the thumb side part 32 places the thumb side part of the foot f0, and the little finger side part 33 places the foot f0. The little finger side portion is placed. The collar portion 31, the thumb side portion 32, and the little finger side portion 33 may be formed by dividing a single plate.

踵部31は、蝶番34を介して、搭乗台2R(図1参照)に回動可能に支持されており、親指側部32は、蝶番35を介して、搭乗台2Rに回動可能に支持されている。また、小指側部33は、蝶番36を介して、搭乗台2Rに回動可能に支持されている。荷重圧センサ群7は、踵側荷重圧センサ71と、親指側荷重圧センサ72と、小指側荷重圧センサ73と、を含む。踵側荷重圧センサ71は、踵部31に設置されている。また、親指側荷重圧センサ72は、親指側部32に設置され、小指側荷重圧センサ73は、小指側部33に設置されている。親指側荷重圧センサ72は搭乗者の足f0の拇指球に対応する位置に設置すると好ましく、小指側荷重圧センサ73は搭乗者の足f0の小指球に対応する位置に設置すると好ましい。具体的には、拇指球は、搭乗者の足の親指の付け根であり、小指球は、搭乗者の足の小指の付け根である。搭乗者の足が踏板3R、3L等の面に載せると、足裏において踵、拇指球、小指球の3点で重心を取ることが多い。その場合、踵、拇指球、小指球が踏板3R、3L等の面に強く押し当たり、荷重を加える。なお、踏板3Lは、本体1の軸に関して左右対称であることを除き、踏板3Rと同様の構成を有する。例えば、踏板3Lでは、小指側部33は親指側部32よりも左側(ここでは、−Y方向)に配置される。   The collar 31 is rotatably supported on the boarding base 2R (see FIG. 1) via a hinge 34, and the thumb side part 32 is rotatably supported on the boarding base 2R via a hinge 35. Has been. Further, the little finger side portion 33 is rotatably supported by the boarding base 2R via a hinge 36. The load pressure sensor group 7 includes a heel side load pressure sensor 71, a thumb side load pressure sensor 72, and a little finger side load pressure sensor 73. The heel side load pressure sensor 71 is installed in the heel part 31. Further, the thumb side load pressure sensor 72 is installed on the thumb side portion 32, and the little finger side load pressure sensor 73 is installed on the little finger side portion 33. The thumb-side load pressure sensor 72 is preferably installed at a position corresponding to the thumb ball of the passenger's foot f0, and the little finger-side load pressure sensor 73 is preferably installed at a position corresponding to the little finger ball of the passenger's foot f0. Specifically, the thumb ball is the base of the thumb of the passenger's foot, and the little finger ball is the base of the little finger of the passenger's foot. When the rider's feet are placed on the surface of the treads 3R, 3L, etc., the center of gravity is often obtained at the three points of the heel, the thumb ball, and the little finger ball on the sole. In that case, the heel, the thumb ball, and the little finger ball strongly press against the surface of the treads 3R, 3L, etc., and a load is applied. The tread 3L has the same configuration as the tread 3R except that the tread 3L is symmetrical with respect to the axis of the main body 1. For example, in the tread 3L, the little finger side portion 33 is disposed on the left side (here, the −Y direction) of the thumb side portion 32.

ハンドル5は、ロッド5aと、接続部5bと、支持ロッド5cと、ハンドルバー5dとを含む。ロッド5aは、本体1の前側から上方に延びて、接続部5bを介して支持ロッド5cと接続する。支持ロッド5cは、本体1の上側後方へ延びて、ハンドルバー5dを支持する。ハンドルバー5dの両端には、グリップ5eR、5eLがそれぞれ設置されている。   The handle 5 includes a rod 5a, a connecting portion 5b, a support rod 5c, and a handle bar 5d. The rod 5a extends upward from the front side of the main body 1 and is connected to the support rod 5c via the connection portion 5b. The support rod 5c extends to the upper rear side of the main body 1 and supports the handle bar 5d. Grips 5eR and 5eL are respectively installed at both ends of the handle bar 5d.

次に、倒立二輪台車100の制御系について説明する。   Next, the control system of the inverted motorcycle 100 will be described.

図7に示すように、制御部9は、足裏割合算出部91と、回復度判定部92と、目標生成部93と、モータドライバ94とを含む。   As shown in FIG. 7, the control unit 9 includes a sole ratio calculation unit 91, a recovery degree determination unit 92, a target generation unit 93, and a motor driver 94.

足裏割合算出部91は、荷重圧情報を荷重圧センサ群7から受けて、荷重圧情報に基づいて、足裏接地時間Tgと重心揺動時間Tsとの比Rtを算出する。比Rtは、搭乗者の足裏全体が踏板3R、3Lに載った時間の割合に相当する。   The sole ratio calculation unit 91 receives load pressure information from the load pressure sensor group 7 and calculates a ratio Rt between the sole contact time Tg and the center of gravity swing time Ts based on the load pressure information. The ratio Rt corresponds to the ratio of the time when the entire foot of the passenger is placed on the treads 3R, 3L.

回復度判定部92は、足裏接地時間Tgと重心揺動時間Tsとの比Rtに基づいて、搭乗者の回復度合を算出する。例えば、足裏接地時間Tgと重心揺動時間Tsとの比Rtが閾値を超えた場合に、「回復済み」と判定し、超えなかった場合に、「未回復」と判定する。   The degree-of-recovery determination unit 92 calculates the degree of recovery of the passenger based on the ratio Rt between the sole contact time Tg and the center-of-gravity swing time Ts. For example, when the ratio Rt between the sole contact time Tg and the center-of-gravity swing time Ts exceeds the threshold, it is determined as “recovered”, and when it does not exceed, the determination is “not recovered”.

目標生成部93は、姿勢角センサ群8から姿勢角度情報を受けて、姿勢角度情報に基づいて、目標トルク値を算出する。なお、目標トルク値は、重心揺動訓練の課題レベルに応じて、設定されてもよい。   The target generation unit 93 receives posture angle information from the posture angle sensor group 8 and calculates a target torque value based on the posture angle information. The target torque value may be set according to the task level of the center of gravity swing training.

モータドライバ94は、目標生成部93から目標トルク値を受けて、目標トルク値に基づいて、車輪4R、4Lを駆動させるための電流をモータ10に供給する。モータ10は、モータドライバ94から電流を得て、車輪4R、4Lを駆動させる。   The motor driver 94 receives the target torque value from the target generation unit 93 and supplies the motor 10 with current for driving the wheels 4R and 4L based on the target torque value. The motor 10 obtains current from the motor driver 94 and drives the wheels 4R and 4L.

制御方法.
次に、図3を参照しつつ、実施の形態1にかかる倒立二輪台車の制御方法について説明する。図3は、実施の形態1にかかる倒立二輪台車の制御方法を示すフローチャートである。
Control method.
Next, the control method of the inverted two-wheeled carriage according to the first embodiment will be described with reference to FIG. FIG. 3 is a flowchart illustrating a method of controlling the inverted two-wheel vehicle according to the first embodiment.

まず、搭乗者の足の回復度の計測及び判定を開始し(計測判定開始ステップS1)、倒立二輪台車100が重心揺動モード状態になっているか否かを判定する(重心揺動モード判定ステップS2)。重心揺動モード状態は、倒立二輪台車100が重心揺動装置として制御される状態である。搭乗者は、倒立二輪台車100を重心揺動モード状態にさせることで、重心揺動訓練することができる。倒立二輪台車100が重心揺動モード状態であると判定した場合(YES:重心揺動モード判定ステップS2)、重心揺動時間Tsを計測する(重心揺動時間カウントアップステップS3)。重心揺動時間Tsは、例えば、倒立二輪台車100が重心揺動モード状態であると判定された時点から、重心揺動モード状態が解除される時点までの時間である。重心揺動時間Tsは、搭乗者が重心揺動訓練を行った時間に相当する。具体的には、重心揺動時間Tsの計測は、倒立二輪台車100が重心揺動モード状態であると判定した時点t1から開始する。   First, measurement and determination of the degree of recovery of the passenger's feet are started (measurement determination start step S1), and it is determined whether or not the inverted two-wheeled carriage 100 is in the center of gravity swing mode state (center of gravity swing mode determination step). S2). The center of gravity swing mode state is a state in which the inverted two-wheel carriage 100 is controlled as a center of gravity swing device. The passenger can perform the center of gravity swing training by setting the inverted two-wheeled carriage 100 to the center of gravity swing mode. When it is determined that the inverted two-wheeled carriage 100 is in the center of gravity swing mode state (YES: center of gravity swing mode determination step S2), the center of gravity swing time Ts is measured (center of gravity swing time count up step S3). The center-of-gravity swing time Ts is, for example, the time from when it is determined that the inverted two-wheeled carriage 100 is in the center-of-gravity swing mode state to when the center-of-gravity swing mode state is canceled. The center-of-gravity swing time Ts corresponds to the time when the passenger has performed center-of-gravity swing training. Specifically, the measurement of the center-of-gravity swing time Ts starts from time t1 when it is determined that the inverted two-wheeled carriage 100 is in the center-of-gravity swing mode.

続いて、踵側荷重圧センサ71と、親指側荷重圧センサ72と、小指側荷重圧センサ73とから荷重圧情報を取得する(荷重圧情報取得ステップS4)。踵側荷重圧センサ71と、親指側荷重圧センサ72と、小指側荷重圧センサ73とが所定の荷重値より大きい荷重を検出するか否かを判定する(踵、拇指球、小拇指球の乗車ON判定ステップS5)。所定の荷重値は、搭乗者の踵、拇指球、小拇指球がそれぞれ踵部31と、親指側部32と、小指側部33とに載せた時の値である。搭乗者が右足裏全体で踏板3Rを踏んでいる場合、踵側荷重圧センサ71と、親指側荷重圧センサ72と、小指側荷重圧センサ73とが所定の荷重値より大きい荷重を検出する。   Subsequently, load pressure information is acquired from the heel side load pressure sensor 71, the thumb side load pressure sensor 72, and the little finger side load pressure sensor 73 (load pressure information acquisition step S4). It is determined whether or not the heel side load pressure sensor 71, the thumb side load pressure sensor 72, and the little finger side load pressure sensor 73 detect a load larger than a predetermined load value. ON determination step S5). The predetermined load value is a value when the passenger's heel, thumb ball, and little finger ball are placed on the heel part 31, the thumb side part 32, and the little finger side part 33, respectively. When the passenger is stepping on the tread 3R with the entire right foot sole, the heel side load pressure sensor 71, the thumb side load pressure sensor 72, and the little finger side load pressure sensor 73 detect a load greater than a predetermined load value.

続いて、足裏接地時間Tgを計測する(足裏接地時間カウントアップステップS6)。足裏接地時間Tgの計測は、踵側荷重圧センサ71と、親指側荷重圧センサ72と、小指側荷重圧センサ73とが所定の荷重値より大きい荷重を検出した時点t2から、開始する。所定の荷重値より小さい荷重を検出したときには、計測を中断してもよい。また、足裏接地時間Tgは、搭乗者が足裏全体で踏板3Rを踏んだ時間に相当する。   Subsequently, the sole contact time Tg is measured (the sole contact time count-up step S6). The measurement of the sole contact time Tg starts from time t2 when the heel side load pressure sensor 71, the thumb side load pressure sensor 72, and the little finger side load pressure sensor 73 detect a load greater than a predetermined load value. When a load smaller than a predetermined load value is detected, the measurement may be interrupted. The sole contact time Tg corresponds to the time when the passenger steps on the foot plate 3R with the entire sole.

続いて、足裏接地時間Tgと重心揺動時間Tsとの比Rtを算出する(足裏接地時間/重心揺動時間の算出ステップS7)。重心揺動訓練が終了する時点t3では、足裏接地時間Tg及び重心揺動時間Tsの計測を終了する。比Rtは、下記の数式1を用いて、求められる。
Rt=Tg/Ts …(数式1)
Subsequently, a ratio Rt between the sole contact time Tg and the center-of-gravity swing time Ts is calculated (step S7 for calculating the sole contact time / center-of-gravity swing time). At the time t3 when the center of gravity swing training ends, the measurement of the sole contact time Tg and the center of gravity swing time Ts ends. The ratio Rt is obtained using the following formula 1.
Rt = Tg / Ts (Formula 1)

続いて、足裏接地時間Tgと重心揺動時間Tsとの比Rtに基づいて、回復度を判定する(回復度判定ステップS8)。回復度は、例えば、足裏接地時間Tgと重心揺動時間Tsとの比Rtが所定の判定値以上であるか未満かで、判定される。   Subsequently, the degree of recovery is determined based on the ratio Rt between the sole contact time Tg and the center-of-gravity swing time Ts (recovery level determination step S8). The degree of recovery is determined, for example, by determining whether the ratio Rt between the sole contact time Tg and the center of gravity swing time Ts is greater than or less than a predetermined determination value.

例えば、図4に示すように、重心揺動訓練の課題レベルに応じて、所定の判定値をそれぞれ設けてもよい。図4は、訓練課題レベルに対する回復度判定基準を示すグラフである。回復度判定基準は、足裏接地判定値である。例えば、足裏接地時間Tgが、足裏接地判定値を超えると「回復済み」と判定し、超えないと「未回復」と判定する。重心揺動訓練の課題レベルが難化するにつれて、その判定値が高くなるように、設定される。なお、重心揺動訓練の課題レベルが難化するにつれて、揺動の大きさが大きくなる。   For example, as shown in FIG. 4, a predetermined determination value may be provided according to the task level of the center of gravity swing training. FIG. 4 is a graph showing recovery criteria for the training task level. The recovery criterion is a foot contact determination value. For example, when the sole contact time Tg exceeds the sole contact determination value, it is determined as “recovered”, and when it does not exceed, it is determined as “unrecovered”. As the task level of the center of gravity swing training becomes difficult, the determination value is set higher. In addition, the magnitude | size of rocking | fluctuation becomes large as the subject level of gravity center rocking | fluctuation training becomes difficult.

最後に、搭乗者の足の回復度の計測及び判定を完了する(計測判定終了ステップS9)。なお、再び計測判定する場合、計測判定開始ステップS1に戻る。   Finally, measurement and determination of the degree of recovery of the passenger's feet are completed (measurement determination end step S9). In addition, when measuring determination again, it returns to measurement determination start step S1.

以上、実施の形態1にかかる倒立二輪台車によれば、踏板が複数の部位を有し、複数の部位はそれぞれ独立している。足裏の外側部分、又は、内側部分を踏板に載せている状態と、足裏全体を踏板に載せている状態とを判別できる。搭乗者が踏板の一部を踏んでも、搭乗者の乗車を誤って検出するおそれが少ない。したがって、この重心揺動訓練では、足の硬縮の回復度合いの判定を誤るおそれが小さい。   As described above, according to the inverted two-wheel vehicle according to the first embodiment, the tread has a plurality of parts, and the plurality of parts are independent of each other. It is possible to distinguish between a state where the outer part or the inner part of the sole is placed on the tread and a state where the entire sole is placed on the tread. Even if the passenger steps on a part of the tread board, there is little risk of erroneously detecting the passenger's boarding. Therefore, in this center-of-gravity swing training, there is little risk of erroneous determination of the degree of recovery of leg stiffness.

また、実施の形態1にかかる倒立二輪台車によれば、踏板の部位は、足裏の部位である踵、親指側、小指側に対応し、複数の荷重圧センサがこれらの各部位の接地を検出する。搭乗者の乗車を誤って検出するおそれがより少ない。   In addition, according to the inverted two-wheeled carriage according to the first embodiment, the tread board portions correspond to the heel, thumb side, and little finger side, which are the sole portions, and a plurality of load pressure sensors ground each of these portions. To detect. There is less risk of erroneous detection of passengers.

また、実施の形態1にかかる倒立二輪台車によれば、重心揺動訓練中に足裏接地の有無を考慮した回復度の判定を行うことができる。   Further, according to the inverted two-wheeled carriage according to the first embodiment, it is possible to determine the degree of recovery in consideration of the presence or absence of the foot contact during the center of gravity swing training.

Since the heel part 231, the thumb ball part 232, and the little finger ball part 233 are substantially square plates, they can be arranged at preferred positions according to the shape of the passenger's foot f0. Thereby, the load from the passenger's foot f0 can be detected more appropriately.

続いて、図6に示す踏板33Rは、踏板3Rの別の変形例である。踏板33Rは、中央部331と、親指側部332と、小指側部333とを含む。センサ群37は、踵側荷重圧センサ371と、親指側荷重圧センサ372と、小指側荷重圧センサ373とを含む。親指側部332、中央部331、及び、小指側部333は、略長方形状板であり、搭乗者の足f0の拇指球f2から小指球f3に向かう方向(ここでは、Y方向)に順に並ぶ。親指側部332、中央部331、及び、小指側部333の長手方向は、搭乗者の足f0の長手方向に沿う。搭乗者の足f0の長手方向は、倒立二輪台車100の前後方向(ここでは、X方向)に沿う。親指側部332、中央部331、及び、小指側部333の長手方向の長さは、搭乗者の足f0の長手方向の長さと同じ、又は、長い。中央部331と、親指側部332と、小指側部333とは、一枚の板を分割して形成してもよい。   Subsequently, a tread 33R shown in FIG. 6 is another modification of the tread 3R. The footboard 33R includes a central portion 331, a thumb side portion 332, and a little finger side portion 333. The sensor group 37 includes a heel side load pressure sensor 371, a thumb side load pressure sensor 372, and a little finger side load pressure sensor 373. The thumb side portion 332, the center portion 331, and the little finger side portion 333 are substantially rectangular plates, and are sequentially arranged in a direction (here, Y direction) from the thumb ball f2 of the passenger's foot f0 to the little finger ball f3. . The longitudinal direction of the thumb side portion 332, the central portion 331, and the little finger side portion 333 is along the longitudinal direction of the passenger's foot f0. The longitudinal direction of the passenger's foot f0 is along the front-rear direction (here, the X direction) of the inverted two-wheeled carriage 100. The length in the longitudinal direction of the thumb side portion 332, the central portion 331, and the little finger side portion 333 is the same as or longer than the length in the longitudinal direction of the passenger's foot f0. The central portion 331, the thumb side portion 332, and the little finger side portion 333 may be formed by dividing one plate.

踵側荷重圧センサ371は中央部331の後側に設置され、親指側荷重圧センサ372は親指側部332の前側に設置される。また、小指側荷重圧センサ373は小指側部333の前側に設置される。踵側荷重圧センサ371、親指側荷重圧センサ372、及び、小指側荷重圧センサ373は、搭乗者の足f0に応じて、配置されるとよい。具体的には、踵側荷重圧センサ371は、搭乗者の足f0の踵f1に当たるように配置される。また、親指側荷重圧センサ372は、搭乗者の足f0の拇指球f2に当たるように配置され、小指側荷重圧センサ373は、搭乗者の足f0の小指球f3に当たるように配置される。これによって、重心揺動訓練中に、足の硬縮の回復度合いの判定を誤るおそれがより小さい。   The heel side load pressure sensor 371 is installed on the rear side of the central portion 331, and the thumb side load pressure sensor 372 is installed on the front side of the thumb side portion 332. The little finger side load pressure sensor 373 is installed on the front side of the little finger side portion 333. The heel-side load pressure sensor 371, the thumb-side load pressure sensor 372, and the little finger-side load pressure sensor 373 may be arranged according to the passenger's foot f0. Specifically, the heel side load pressure sensor 371 is disposed so as to hit the heel f1 of the passenger's foot f0. Further, the thumb side load pressure sensor 372 is disposed so as to hit the thumb ball f2 of the passenger's foot f0, and the little finger side load pressure sensor 373 is disposed so as to contact the little finger ball f3 of the passenger's foot f0. This reduces the risk of erroneous determination of the degree of recovery of leg stiffness during the center of gravity swing training.

なお、本発明は上記実施の形態に限られたものではなく、趣旨を逸脱しない範囲で適宜変更することが可能である。   Note that the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention.

例えば、実施の形態1にかかる制御部9は姿勢角情報に基づいて車輪4R,4Lを駆動させるが、制御部9は重心情報に基づいて車輪4R,4Lを駆動させてもよい。このような場合、制御部9は重心判定部を備える。重心判定部は、荷重圧センサ群7から荷重圧情報を受けて、搭乗者の重心を判定する。また、目標生成部は、重心判定部が判定した搭乗者の重心に基づいて、目標トルク値を生成する。上記した実施の形態1と同様に、重心揺動訓練中に足裏接地の有無を考慮した回復度の判定を行うことができる。   For example, the control unit 9 according to the first embodiment drives the wheels 4R and 4L based on the posture angle information, but the control unit 9 may drive the wheels 4R and 4L based on the center of gravity information. In such a case, the control unit 9 includes a center of gravity determination unit. The center of gravity determination unit receives the load pressure information from the load pressure sensor group 7 and determines the center of gravity of the passenger. The target generation unit generates a target torque value based on the passenger's center of gravity determined by the center of gravity determination unit. Similar to the first embodiment described above, it is possible to determine the degree of recovery in consideration of the presence or absence of sole contact during the center of gravity swing training.

また、搭乗者のバランス能力についても、回復度判定基準としてバランス判定値を用いて判定することができる。バランス判定値は、揺動によって変化した重心の中心からの距離の所定の値である。図4に示すように、バランス判定値は、重心揺動訓練の課題レベルに応じて、設定される。例えば、揺動によって変化した重心の中心からの距離が、バランス判定値を超えると「回復済み」と判定し、超えないと「未回復」と判定する。   The balance ability of the passenger can also be determined using the balance determination value as the recovery degree determination criterion. The balance determination value is a predetermined value of the distance from the center of the center of gravity that has changed due to rocking. As shown in FIG. 4, the balance determination value is set according to the task level of the center-of-gravity swing training. For example, if the distance from the center of the center of gravity changed by the swing exceeds the balance determination value, it is determined as “recovered”, and if not exceeded, it is determined as “unrecovered”.
