Object To provide an inverted pendulum type vehicle on which an occupant can get easily in a forwardly directed posture from the rear of a vehicle body. Solving Means An inverted pendulum type vehicle 1 which includes a seat 200 for being seated includes a main wheel 52 driven based on inverted pendulum control, a vehicle body frame 10 which supports the main wheel, and a tail wheel 82 attached to a tail wheel arm 78 supported for pivotal motion on the vehicle body frame. The seat is attached to the vehicle body frame so as to be positioned at an uppermost portion of the vehicle body. The vehicle body frame pivots rearwardly around an axle 54 of the driving wheel together with the seat upon cancellation of the inverted pendulum control and the range of pivotal motion thereof is limited by contact thereof with the arm.

An inverted pendulum type vehicle prevents a travel operation unit from running at a high velocity when not in contact with the ground. A ground contact point velocity detector integrates a ground contact point horizontal acceleration calculated by a ground contact point horizontal acceleration calculator so as to calculate the acceleration at the ground contact point of a wheel. A determiner calculates a ground contact point velocity. The determiner sets a velocity threshold value on the basis of the velocity difference between the ground contact point velocity and a first desired velocity. If the first desired velocity reaches the velocity threshold value or more, then the determiner decides that the wheel of a first travel operation unit is idling and restricts the setting of the first desired velocity by a first control processor to the velocity threshold value or less.

An inverted pendulum type vehicle with a tiltable rider mounting section has a first travel operation unit and a second travel operation unit, which are disposed with an interval provided therebetween in the longitudinal direction and which are capable of traveling in all directions. In a situation wherein a predetermined representative point of the vehicle or the first travel operation unit is to be moved rightward or leftward, the traveling operations of the first travel operation unit and the second travel operation unit are controlled such that the travel velocity of the first travel operation unit and the travel velocity of the second travel operation unit in the lateral direction are different from each other.

A bicycle frame comprising a first tubular member having a first interface portion, and a second tubular member having a second interface portion engaged with the first interface portion to create a joint. The joint includes a peripheral channel having a depth that is greater than a wall thickness of the first tubular member, and a weld is positioned in the peripheral channel. To enhance the transition from the first main portion to the second main portion, the second tubular member can include a fillet surface between the second main portion and the second interface portion. The fillet surface is contoured to provide a smooth transition between the top tube and the head tube. An outer surface of the first interface portion can be offset from an outer surface of the first main portion to thereby create a shoulder.

The present invention provides a falling prevention controlling device and a computer program that, with a simple configuration, can precisely correct the inclination in a pitch direction with respect to the balanced state while securing movement in the front-back direction, without the accumulating a noise and an offset, and prevent a falling in the pitch direction. The falling prevention controlling device has a wheel, and a main body which swings in a pitch direction and a roll direction above the wheel, and has: an advance/retreat command receiving unit 42 which receives an advance or a retreat command of the wheel; a target pitch angle calculating unit 44 which calculates a target pitch angle based on the received command and a rotation velocity deviation in the pitch direction derived from the detected rotation angle; a pitch inclined angle estimating unit 47 which estimates a pitch inclined angle with respect to a balanced state, from the detected pitch angular velocity and a pitch torque command generated based an the target pitch angle; and a pitch torque command generating unit 49 which generates the pitch torque command based an the target pitch angle and the pitch inclined angle.

The invention relates to a foot-propelled, wheeled hobby and/or sport device that has a foot plate. Characteristic of the device is that it has one or two wheels (1) positioned between two side plates (7, 8) the axle (3) of which wheel (1) is fixed to the side plates (7, 8). Positioned under the wheel (1) axle (3) there are foot plates (9, 10) extending outwards connected to the side plates (7, 8). During the normal use of the device the side plates (7, 8) extend above the knee (21) of the person using the device, who is standing on either one or both of the foot plates (9, 10).

The invention relates to a foot-propelled wheeled hobby and/or sport device which has a wheel (1) situated between two side-plates (2; 3), and the side-plates (2; 3) are suspended on the axle (X) of the wheel (1). Foot-boards (5) situated below the axle (X) of the wheel (1). Foot-boards (5) situated below the axle (X) of the wheel (1), protruding outwards are connected to the side-plates (2; 3). In the course of the appropriate use of the device (I; II) the side-plates (2; 3) project over the knee of the user (12) standing on one or both of the foot-boards (5), providing a supporting surface (a) for the knee. The invention is based on that at a certain distance (e) behind the wheel (1) - with respect to the travelling direction - there is a structure in the range of the track of the wheel (1) ensuring stabilisation against tilting, and in order to relieve the knees of any load the side-plates (3) are constructed with a height (L) ensuring a supporting surface (b) for the user's (12) thigh.

Die Erfindung betrifft ein elektrisches Einrad- Fahrzeug mit einem gabelförmigen Rahmen (A), einem drehend gelagerten Rad (B) und einem Elektromotor (C) mit mechanischem Getriebe (D), einschließlich Antriebselektronik und Regelung (E). Zur Erzielung eines stabilen Betriebs und einer leichten Bedienbarkeit ist erfindungsgemäß vorgesehen, daß die reine Motorregelung des Einradantriebs von einem überlagerten Neigungswinkelregler (K) plus Neigungswinkelsensor (F) geführt wird, der das labile Gleichgewicht des Fahrzeugs in der Art eines inversen Pendels stabilisiert. Durch diese Maßnahme wird einerseits eine stabile Ruhelage des Einrad-Fahrzeugs erreicht und andererseits die Vorwärts- oder Rückwärtsfahrt durch eine leichte Schwerpunktsverlagerung des Benutzers nach vorne oder hinten ohne Bedienelemente möglich Die Querstabilität des Einrad-Fahrzeugs ist über eine ausreichende Breite des Rades sichergestellt.
