The disclosure supports accident prevention or evacuation action of a user who is on board a moving body when a disaster occurs. A moving body control device includes: a moving body control part that controls a moving body maintained in a first state or a second state that is more stable than the first state by a balance control mechanism; and an event detection part that detects an occurrence of a predetermined event. The moving body control part stops the moving body from traveling and causes the moving body to change to the second state regardless of a driving operation of the moving body by an occupant of the moving body in a case where the event detection part detects the occurrence of the predetermined event.

The disclosure allows an occupant to control a vehicle as needed for the vehicle that automatically moves to a destination. An inverted pendulum type vehicle that travels while balancing an inverted pendulum type body includes: an operation input part that receives a driving operation of its own vehicle by a weight shift of an occupant; and a movement control part that causes the own vehicle to start automatic movement on a predetermined route at a predetermined time. The movement control part allows the own vehicle to deviate from the predetermined route and travel in a second direction when a weight shift greater than a threshold value is performed in the second direction other than a traveling direction related to the predetermined route during execution of the automatic movement.

In a frictional propulsion device comprising a frame, a main wheel including driven rollers rotatably supported by an annular core member about a tangential direction and a pair of drive disks each carrying drive rollers rotatable about a rotational center line at an angle with respect to both a tangential line of the drive disk and the rotational center line of the drive disk such that the drive rollers at least partly engage the driven rollers, each drive disk includes a hub rotatably supported by the support shaft, a disk member attached to a peripheral part of the hub, and holder beams arranged circumferentially between the hub and the disk member such that each holder beam is attached to the hub at a first end thereof and to the disk member at a second end thereof, each drive roller being rotatably supported by a corresponding adjoining pair of holder beams.

A self-propelled, one-wheeled vehicle may include a suspension system configured to dampen up and down motion of a board relative to the axle of a central wheel assembly when the vehicle encounters obstacles and bumps on a riding surface. Illustrative suspension systems include a shock absorber, a rocker, a pushrod, bell cranks, and/or a swingarm that couple the axle to the board. The suspension system may be disposed completely below a foot deck of the vehicle.

A foldable structure of an electric vehicle is disclosed. In the foldable structure, a frame defines a stowing space, and includes a connection base and a rotatable seat. The connection base has a chute and the seat includes a link rod. The wheel part includes two wheel casings, a tire and a driving device, and a containing space is formed between the wheel casings for containing the tire and the driving device. The wheel casings has a rotator cap protruded at tops thereof, and the rotator cap has an axle hole longitudinally cut therethrough, and the rotator cap is pivotally connected with the rotatable seat by the axle hole, whereby the link rod can be slid into the chute, and the two wheel casings and the tire can be laterally rotated into the stowing space, such that the electric vehicle can just occupy smaller space.

A water shield structure for a transportation device and the transportation device having such a water shield structure. The transportation device is preferably a self-balancing device and may include a friction drive motor. The water shield structure helps reduce the entry of moisture from a riding surface into the wheel envelope or drive mechanism of the device. The water shield structure may extend laterally from a wheel and be enclosed, at least in part, in a housing.

A vehicle for the movement of a driver includes a rolling element, a carrier element supported by the rolling element, a drive arrangement supported by the carrier element and configured to drive the rolling element, and a control unit, by way of which the drive arrangement is steered in a desired travel direction depending on the inclination of the carrier element and the inclination direction of the carrier element. The vehicle is configured such that during operation of the vehicle, the driver stands freely and balances on the carrier element. In a particular embodiment, the rolling element rolling is a ball and the vehicle can be moved in any desired travel direction via the drive arrangement, with the driver being in contact with the vehicle exclusively by way of the driver's feet, and as the case may be, further by way of the driver's lower legs.
