    Abstract: A support unit is connected to a shaft of a main wheel and thus is always maintained in parallel to or at a predetermined angle to a road surface, independently of an inclination angle of a main body. Accordingly, an incline estimating unit regards an inclination angle θ3 being a value in an inclination sensor as being equal to an inclination angle θ2 of the road surface (or in a case where the support unit is inclined a predetermined angle to the road surface, an angle from θ3 to the predetermined angle is subtracted from or added to the crossing angle) and outputs the estimated inclination angle θ2 of the road surface to a target inclination angle determining unit.

    Abstract: A manually propelled vehicle includes a main body part comprising a wheel and a motor that drives the wheel when a user pushes the main body part in an advancing direction, and a mounting unit to be carried by the user and that communicates with the main body part. The mounting unit comprises a first motion sensor comprising an acceleration sensor in three orthogonal directions, and the main body part controls a drive of the motor based on a detection result of the first motion sensor.

    Abstract: A power assist device for assisting a user to operate an object. The power assist device includes a pressure sensor that detects an operating force applied to the object by the user; a motor that outputs and applies a motive force to the object; and a controller. The controller records a history of the operating force detected by the pressure sensor; detects a periodically fluctuating component of the operating force based on the history of the operating force; calculates a component of a current operating force caused by motion of the user operating the object; calculates a correction value that excludes the component caused by motion of the user from the current operating force; calculates a power assist force based on the correction value; and outputs the power assist force as the motive force of the motor.
