Abstract

An electric vehicle includes a base; a front wheel that can be driven omnidirectionaly; a rear wheel that is mounted on the base so that a symmetry axis is parallel with a symmetry axis of the front wheel; a seat member that is mounted so that a straight line connecting a wheel center of the front wheel and a wheel center of the rear wheel specifies a fore-and-aft direction; an controller that detects an acceleration and deceleration command and a turning command; an inclination sensor that detects inclination of the base; and a control unit that controls acceleration and deceleration of the base based on the acceleration and deceleration command detected by the controller, that controls turning of the base based on the turning command detected by the controller, and that controls translational motion of the base based on inclination of the base detected by the inclination sensor.

Claims

1. An electric vehicle comprising:

a base;

a movement operator that has at least one omnidirectional drive wheel which can be driven omnidirectionaly;

a seat member that is mounted on the base;

an acceleration and deceleration command unit that detects an acceleration and deceleration command;

a turning command unit that detects a turning command;

an inclination detection unit that detects an inclination of the base; and

a control unit that controls acceleration and deceleration of the base based on the acceleration and deceleration command detected by the acceleration and deceleration command unit, that controls turning of the base based on the turning command detected by the turning command unit, and that controls translational motion of the base based on the inclination of the base detected by the inclination detection unit.

2. The electric vehicle according to claim 1, wherein

the control unit controls the turning of the base so that incline the base during the turning.

3. The electric vehicle according to claim 1, further comprising:

a rotation center position determination unit that determines a position of a rotation center during the turning according to at least one of a velocity of the base or an acceleration of the base.

4. The electric vehicle according to claim 2, further comprising:

a rotation center position determination unit that determines a position of a rotation center during the turning according to at least one of a velocity of the base or an acceleration of the base.

5. An electric vehicle comprising:

a base;

a first omnidirectional drive wheel that is mounted on the base and can be driven omnidirectionaly;

a second omnidirectional drive wheel that is mounted on the base so that a symmetry axis thereof is parallel with a symmetry axis of the first omnidirectional drive wheel;

a seat member that is mounted so that a straight line connecting a wheel center of the first omnidirectional drive wheel and a wheel center of the second omnidirectional drive wheel specifies a fore-and-aft direction;

an acceleration and deceleration command unit that detects an acceleration and deceleration command;

a turning command unit that detects a turning command;

an inclination detection unit that detects inclination of the base; and

a control unit that controls acceleration and deceleration of the base based on the acceleration and deceleration command detected by the acceleration and deceleration command unit, that controls turning of the base based on the turning command detected by the turning command unit, and that controls translational motion of the base based on the inclination of the base detected by the inclination detection unit.

6. The electric vehicle according claim 5, wherein

the straight line is parallel to the fore-and-aft direction of the seat member.
