Abstract

A standing-ride type moving device includes: a board; wheels that are disposed on right and left sides of a front side and a rear side in a traveling direction of the board; drive units that is configured to independently rotationally drive the wheels disposed on the front side in the traveling direction of the board; a first sensor that is configured to detect a shift in the center of gravity of the rider riding the board; a steering board that is disposed on the front side in the traveling direction of the board; a second sensor that that is configured to acquire rotation information of the steering board; and a control unit that is configured to control the drive units.

First claim

What is claimed is:

1. A standing-ride type moving device comprising:
a board that a rider rides;
wheels that are disposed on right and left sides of a front side and a rear side in a traveling direction of the board;
a first drive unit that is configured to independently rotationally drive the wheel disposed on the right side in the traveling direction of the board on at least one of the front side and the rear side in the traveling direction of the board;
a second drive unit that is configured to independently rotationally drive the wheel disposed on the left side in the traveling direction of the board to correspond to the wheel rotationally driven by the first drive unit;
a first sensor that is configured to detect a shift in a center of gravity of the rider riding the board;
a steering board that is disposed on at least one of the front side and the rear side in the traveling direction of the board and is rotatable about a rotational axis extending in a vertical direction;
a second sensor that is configured to acquire rotation information of the steering board; and
a control unit that is configured to control the first and second drive units,
wherein the control unit controls rotation speeds of the first and second drive units based on the shift in the center of gravity of the rider detected by the first sensor to control a speed in the traveling direction of the board and turns the board in a direction corresponding to the rotation information by independently controlling the rotation speeds of the first and second drive units based on the rotation information acquired by the second sensor.

2. The standing-ride type moving device according to claim 1 , wherein the control unit controls the first and second drive units such that a turning radius of the board in which the board is turned increases as the rotation speeds of the first and second drive units increase.

3. The standing-ride type moving device according to claim 1 , wherein the control unit controls the first and second drive units such that a turning radius of the board in which the board is turned decreases as the rotation speeds of the first and second drive units decrease.

4. The standing-ride type moving device according to claim 1 , wherein the control unit controls the first and second drive units such that a turning radius of the board in which the board is turned varies linearly with respect to the rotation information of the steering board acquired by the second sensor when the rotation speeds of the first and second drive units are lower than a predetermined rotation speed.

5. The standing-ride type moving device according to claim 1 , further comprising a rectangular frame that is disposed between the board and the wheels,
wherein the first sensor is disposed at four corners of the frame to be interposed between the frame and the board.

6. The standing-ride type moving device according to claim 1 , wherein the board includes a recessed portion in which the steering board is rotatably disposed.

7. The standing-ride type moving device according to claim 1 , wherein the second sensor is a rotation angle sensor.

8. The standing-ride type moving device according to claim 1 , wherein the second sensor is a torque sensor.

9. The standing-ride type moving device according to claim 1 , wherein the first sensor is a multiaxial sensor that is disposed at a center of the board.
