Abstract
A device for inducing a user's motion in a rhythm responsive to a motion rhythm after the user's motion rhythm changes suddenly. The walking assist device generates a first oscillator which attains mutual entrainment with a user's hip joint angular velocity to reflect a natural angular velocity. On the other hand, a new natural angular velocity is set based on the phase difference between the hip joint angular velocity and the first oscillator. A second oscillator which oscillates in rhythm reflecting the natural angular velocity is generated. An inducing oscillator is generated based on the second oscillator, and a torque responsive to the inducing oscillator acts on the user's body. If the magnitude of a periodic variation in the hip joint angular velocity exceeds a threshold value, a second oscillator which oscillates in rhythm reflecting the angular velocity of the first oscillator instead of the natural angular velocity is generated.
