Abstract

Quantifying Roll Feel of a Car by Using a Musculoskeletal Mathematical Model

Highlights

Popularity of cars vastly affected our society to enrich our lives as they became ubiquitous
7 Conclusion We can draw following conclusions: 1. Creation of a valid musculoskeletal mathematical model of a driver while controlling a vehicle was enabled through a motion capture system used to examine inside the car
Our observation shows it is easier for the driver to control the vehicle when an appropriate rolling posture is realized

Summary

Introduction

Popularity of cars vastly affected our society to enrich our lives as they became ubiquitous. In terms of the roll feel evaluation, it is inequivalent in a way that roll feel is a combination of assessment on handling and reception of the roll feel (sensory evaluation) This topic has been broadly attracting attention of automotive engineers to explain the mechanism such as research on the phase portrait between roll rate and pitch rate examined in association with physical value of a car and sensory evaluation, studies on relationships between physical value of a car and surface EMG, brain waves and sensory evaluation of roll feel using biological indexes [Tao, Sugimacgi, Suda et al (2016); Yoshioka, Abe, Yamakado et al (2017)]. The knee-joint angle is given as knee in Fig. 5. knee can be calculated by converting the positions of reflection markers fixed to the center of rotation of the knee joint and reflection markers fixed to the thighs and lower legs (captured by amotion-capture camera) into three-dimensional coordinate data
