    Abstract: The direction of a component vector on a plane perpendicular to a predetermined axis (Y axis) of a floor reaction force acting on each landing leg (2) is determined in such a way that the direction of a moment generated around a center-of-gravity of a two-legged walking mobile body (1) by a total sum of the component vectors on the plane perpendicular to the predetermined axis (Y axis) of the floor reaction forces acting on the landing legs (2) is coincident with the direction of the component around the predetermined axis (Y axis) of a total rate of change of angular momentum by calculating the total rate of change of angular momentum, which is a time rate of change of an angular momentum around an total center-of-gravity of the two-legged walking mobile body (1), and the total floor reaction force acting on the two-legged walking mobile body (1) by using an output of a joint displacement sensor, an output of an acceleration sensor, an output of an angular velocity sensor, and a rigid link model or the like. An estimated value of the component vector on the plane perpendicular to the predetermined axis (Y axis) of the floor reaction force on the each leg 2 is found on the basis of the determined direction and the obtained total floor reaction force. This enables finding an estimated value of the floor reaction force showing a smooth and continuous change.

    Abstract: Whether a motion state of leg bodies (2) is a single stance state or a double stance state is sequentially determined and a total reaction force (F) is estimated on the basis of an equation of motion for a center of gravity (G0) of a bipedal walking body (1). If the motion state is the single stance state, then the estimated value of the total floor reaction force (F) is directly used as an estimated value of the floor reaction force of the leg body (2). If the motion state is the double stance state, then a floor reaction force (Fr) of the leg body (2) at the rear side is determined, using measurement data of elapsed time of the double stance state and moving speed of a bipedal walking body (1) and pre-established characteristic data, and the floor reaction force (Fr) is subtracted from the total floor reaction force (F) to determine a floor reaction force (Ff) of the leg body (2) at the front side. Thus, it is possible to provide a method that allows floor reaction forces acting on leg bodies of a bipedal walking body, such as a human being, and moments acting on joints of the leg bodies to be determined in real time with high accuracy by a relatively simple technique.

    Abstract: A control device for a walking assist device is provided. The control device has a means that decides whether the total sum of measured values of treading forces of the legs of a user is greater than a predetermined value and a means which determines a predetermined ratio according to observed values or desired values of reference parameters obtained immediately before a negative determination result by using supporting forces acting on the leg links from the floor side as the reference parameters. This is in the case where the determination result of the decision means is negative and is a process undertaken instead of determining the predetermined ratio between the supporting forces acting on the leg links according to the measured values of the treading forces of the legs of the user.
