WALKING MOTION ASSISTANCE DEVICE

Title:

WALKING MOTION ASSISTANCE DEVICE

Document Type and Number:

WIPO Patent Application WO/2020/195447

Kind Code:

A1

Abstract:

In a walking motion assistance device according to the present invention, a thigh phase angle calculation means has a latest data transmission process for transmitting a thigh phase angle φ(k) at a sampling timing S(k) (k is an integer of 1 or more) to a walking motion timing calculation means and storing the thigh phase angle φ(k) as a reference thigh phase angle φc, and a stored data transmission process for transmitting, instead of the thigh phase angle φ(k) at the timing S(k), the stored reference thigh phase angle φc to the walking motion timing calculation means and maintaining the reference thigh phase angle φc. Only when a condition is satisfied that a thigh phase angle at one timing is smaller than the reference thigh phase angle stored at that time and an absolute value of a deviation thereof is less than or equal to a predetermined threshold value, the thigh phase angle calculation means performs the stored data transmission process, and otherwise performs the latest data transmission process.
