Vehicle steerable by movement of center of gravity
First Claim
1. A vehicle which can be steered based on movement of balance comprising:
- first and second wheels located at least on the same axis;
first rotary drive means for rotating said first wheel and second rotary drive means for rotating said second wheel;
a vehicle base having said first and second wheels located at its right and left sides and which has said first and second rotary drive means mounted on a top surface of the base;
a step-board located above said vehicle base and on which a rider rides;
balance position detecting means interposed between said vehicle base and said step-board to detect a rider'"'"'s balance position, wherein the vehicle can be steered based on the balance position, the balance position detecting means includes a front-side detecting means located ahead of the axis and back-side detecting means located behind the axis; and
drive control means for controlling driving of said first and second rotary drive means to maintain the balanced state of said vehicle based on a detected signal from said balance position detecting means if the balance position is located at the center of balance of said vehicle base, and controlling driving of said first and second rotary drive means to enable said vehicle to travel straight and/or turn if the balance position is not located at the center of balance of said vehicle base.

Abstract
The present invention relates to a vehicle which can travel in the front and back direction and which can turn by right and left wheels rotated when a rider riding on a step-board moves the position of rider'"'"'s balance from the center of a vehicle base.
A vehicle which can be steered based on movement of balance according to the present invention includes left and right wheels 4L and 4R located at least on the same axis, first and second drive motors 5L and 5R for rotating the left and right wheels 4L, 4R, a vehicle base 2 having the left and right wheels located at its left and right sides and which has the first and second drive motors mounted thereon, a step-board 3 located above the vehicle base 2 and on which a rider rides, pressure sensors 6L, 6R, 7L, 7R interposed between the vehicle base and the step-board to detect movement of rider'"'"'s balance and a drive control means 10 for controlling driving of the first and second drive motors based on detected signals from the pressure sensors to enable the vehicle to travel straight and/or turn.
According to the present invention, it is possible for the rider to run the vehicle in the front and back direction and to turn the vehicle in the left and right direction by only moving rider'"'"'s weight.
