Abstract

An inverted pendulum type moving body. The inverted pendulum type moving body includes: a vehicle body having a riding part on which a rider rides; a rotary body which is rotatably supported on the vehicle body; a rotary body drive unit which rotatably drives the rotary body; and a control device which controls the rotary body drive unit for allowing the inverted pendulum type moving body to travel in accordance with a traveling instruction while keeping a balance, wherein the inverted pendulum type moving body further includes an uncontrollable state detection unit for detecting a state where the control of the inverted pendulum type moving body by the rider is highly improbable, and the control device stops a traveling of the inverted pendulum type moving body when the uncontrollable state is detected based on information detected by the uncontrollable state detection unit.

Claims

1. An inverted pendulum type moving body comprising:

a vehicle body having a riding part on which a rider rides;

a rotary body which is rotatably supported on the vehicle body;

a rotary body drive unit which rotatably drives the rotary body; and

a control device which controls the rotary body drive unit for allowing the inverted pendulum type moving body to travel in accordance with a traveling instruction while keeping a balance;

wherein the inverted pendulum type moving body further comprises an uncontrollable state detection unit for detecting an uncontrollable state where the control of the inverted pendulum type moving body by the rider is highly improbable, and

the control device stops a traveling of the inverted pendulum type moving body when the uncontrollable state is detected based on information detected by the uncontrollable state detection unit.

2. The inverted pendulum type moving body according to claim 1, wherein the uncontrollable state detection unit detects falling of the rider using a unit for detecting whether or not the rider is riding on the riding part.

3. The inverted pendulum type moving body according to claim 1, wherein the uncontrollable state detection unit detects falling of the rider by comparing a target rotational speed instructed to the rotary body drive unit and a rotational speed of the rotary body.

4. The inverted pendulum type moving body according to claim 1, wherein the uncontrollable state detection unit detects overturn of the inverted pendulum type moving body using a unit which detects an inclination angle of the vehicle body.

5. The inverted pendulum type moving body according to claim 1, wherein the control device stops traveling of the inverted pendulum type moving body by setting an output of the rotary body drive unit to zero.

6. The inverted pendulum type moving body according to claim 5, wherein the control device sets an output of the rotary body drive unit to zero by gradually decreasing the output.

7. The inverted pendulum type moving body according to claim 1, wherein the control device stops traveling of the inverted pendulum type moving body by shutting off a main power source.
