Study on Physical Workload of Pelvis-circumference in Ingress and Egress

Abstract

An evaluation method is difficult to design a vehicle demension in order to improve the usability of ingress-egress. In this paper, from movement of the waist and hip joint in egress and ingress, the characteristics of physical workload of the pelvis-circumference are clarified. The authors have proposed an evaluation method by estimation the each part o joint moment in place of the evaluation of measuring the muscles of the pelvis-circumference. The experiments are carried out using mock-up of passenger car to verify the effectiveness of the proposed method of workload estimation in egress and ingress from vehicle dimensions.
