Abstract

A balance training device includes an inverted two-wheel vehicle, a posture detection unit that detects a posture of the inverted two-wheel vehicle, a control unit that enables control of the inverted two-wheel vehicle so that the inverted two-wheel vehicle moves according to the posture of the inverted two-wheel vehicle detected by the posture detection unit and control of the inverted two-wheel vehicle so that the inverted two-wheel vehicle is forcibly moved in an arbitrary direction irrespective of the posture of the inverted two-wheel vehicle, and a position determining unit that determines a position of the inverted two-wheel vehicle. When a distance between the obtained position of the inverted two-wheel vehicle and the reference position is greater than or equal to a threshold, the control unit suppresses the control to forcibly move the inverted two-wheel vehicle in a direction from a reference position to the position of the inverted two-wheel vehicle.

First claim

What is claimed is:

1. A balance training device comprising:
an inverted vehicle;
a posture detection unit that detects a posture of the inverted vehicle, the posture changing according to a posture of an occupant riding on the inverted vehicle;
a control unit that controls the inverted vehicle so that the inverted vehicle moves within a predetermined range according to the posture of the inverted vehicle detected by the posture detection unit and controls the inverted vehicle so that the inverted vehicle is forcibly moved in an arbitrary direction irrespective of the posture of the inverted vehicle; and
a position determining unit that determines a position of the inverted vehicle, wherein
when a distance between the position of the inverted vehicle obtained by the position determining unit and a reference position is greater than or equal to a threshold, the control unit suppresses only the control to forcibly move the inverted vehicle in a direction from the reference position to the position of the inverted vehicle when the control unit controls the inverted vehicle so that the inverted vehicle is forcibly moved in an arbitrary direction irrespective of the posture of the inverted vehicle.

2. The balance training device according to claim 1 , wherein the control unit alternately switches between a normal mode in which the control unit controls the inverted vehicle to move within the predetermined range according to the posture of the inverted vehicle detected by the posture detection unit and a challenge mode in which the control unit controls the inverted vehicle to be forcibly moved in an arbitrary direction irrespective of the posture of the inverted vehicle.

3. The balance training device according to claim 2 , wherein the control unit calculates a time that is required for the occupant to return the inverted vehicle from a position that is distant from the reference position by a predetermined distance to the reference position, and the control unit reduces the threshold to become smaller as the calculated time becomes longer.

4. The balance training device according to claim 2 , wherein
the control unit operates at one of a plurality of levels and performs at least one of control to increase the number of times to switch from the normal mode to the challenge mode per unit of time as the level becomes higher and control to increase an amount of movement in the arbitrary direction as the level becomes higher, and
the control unit increases the threshold to be greater as the level becomes higher.

5. An inverted vehicle, comprising:
a posture detection unit that detects a posture of the inverted vehicle, the posture changing according to a posture of an occupant riding on the inverted vehicle;
a control unit that controls the inverted vehicle so that the inverted vehicle moves within a predetermined range according to the posture of the inverted vehicle detected by the posture detection unit and controls the inverted vehicle so that the inverted vehicle is forcibly moved in an arbitrary direction irrespective of the posture of the inverted vehicle; and
a position determining unit that determines a position of the inverted vehicle, wherein
when a distance between the position of the inverted vehicle obtained by the position determining unit and a reference position is greater than or equal to a threshold, the control unit suppresses only the control to forcibly move the inverted vehicle in a direction from the reference position to the position of the inverted vehicle when the control unit controls the inverted vehicle so that the inverted vehicle is forcibly moved in an arbitrary direction irrespective of the posture of the inverted vehicle.

6. The balance training device according to claim 1 , wherein the inverted vehicle includes two wheels.

7. The inverted vehicle according to claim 5 , wherein the inverted vehicle includes two wheels.
