Publication number: 20220168166Abstract: A gait motion assisting apparatus is provided, in which a thigh phase angle calculating unit has a latest data transmission process to transmit a thigh phase angle ?(k) at sampling timing S(k) (k is an integer of 1 or more) to a gait motion timing calculating unit and store the same as a reference thigh phase angle ?c. Also, a stored data transmission process transmits, instead of the thigh phase angle ?(k), a currently stored reference thigh phase angle ?c to the gait motion timing calculating unit and performs the stored data transmission process only when conditions are satisfied such that a thigh phase angle at one sampling timing is smaller than the currently stored reference thigh phase angle and an absolute value of a deviation therebetween is equal to or less than a predetermined threshold, and performs the latest data transmission process in other cases.Type: ApplicationFiled: February 25, 2020Publication date: June 2, 2022Inventors: Rei TAKAHASHI, Yukinobu MAKIHARA, Yuichi SAWADA, Yoshiyuki HIGASHI, Koji OHATA
