Attitude control device

An attitude control device for a vehicle having a tilting function and mounted with a flywheel as an energy storage device,

• said flywheel being pivotally supported about first and second axes mutually orthogonal with each other,
• said flywheel being mounted on a body of the vehicle such that said first axis extends in a front-rear direction of the body,
• said attitude control device comprising:
• locking means for locking movement of the flywheel about said first axis;
• and
• actuating means for moving the flywheel about said second axis,
• wherein a rolling motion of the vehicle is controlled by locking the movement of the flywheel about said first axis using said locking means, and the vehicle body is tilted by moving the flywheel about said second axis using said actuating means.

A support structure for a flywheel, said flywheel being pivotally supported about a first axis and a second axis,

• said support structure comprising:
• locking means for locking movement of the flywheel about said first axis or/and said second axis;
• and
• actuating means for actively moving the flywheel about said first axis or/and said second axis.
