TRAVEL DEVICE
First Claim
1. A travel device comprising:
- a plurality of wheels disposed in parallel;
a step plate mounted between the plurality of wheels for a driver to place feet;
a handle mounted vertically to the step plate;
a driving motor to allow the step plate and the handle to tilt in a roll axis direction, and to drive at least one of the step plate and the handle to tilt in the roll axis direction; and
a control unit to control the driving motor to maintain at least one of a horizontal position of the step plate and a vertical position of the handle; and
a measurement unit to measure a shift operation of at least one of the step plate and the handle from a neutral position in at least one of a horizontal state of the step plate and a vertical state of the handle maintained by the driving motor,wherein the plurality of wheels change a traveling direction according to a value measured by the measurement unit.

Abstract
A two-wheel vehicle having a roll axis rotation flexibility in which a servo motor is mounted to each of two wheels operating independently of each other fails to perform stable straight-forward traveling on a laterally inclined road because a neutral position by a spring force of a handle or a step varies with respect to a vertical axis as a vehicle body tilts in a roll axis direction due to a road slope. Further, in such a device, the handle or the step can tilt against intention due to a left and right unbalanced load of a passenger onto the step when getting on or off the vehicle. There is thus provided a control device that enables stable straight-forward traveling while maintaining a standing posture of a person vertically on a laterally inclined road through a motor control of the position of a handle or a step. There is also provided a control device that enables a rotation while a person maintains a vertical posture when a performing rotation operation on an inclined road. There is also provided a vehicle that prevents the occurrence of an unintended inclination of a handle and a step during loading or unloading of a passenger.
