Modeling of Operating Convenience for Automotive Interior Button Based on Operating Posture and Stature of Driver

Abstract

Abstract:

Although the operation of automotive interior components is a secondary task in the process of vehicle driving, its convenience is closely related to driving safety. An operating time modeling method based on the operation posture and stature of driver is proposed for the automobile interior button. The data of reach posture and operation time of 9 males with different statures are collected in driving status using a vehicle simulator and a human motion capture system. The major factors affecting the operating time are analyzed by a statistical method. Based on these factors, an operating time prediction model is established using principal component regression, and is verified by the data of the test buttons and the other 5 males. The experimental results show that the roll and forward movements of the upper torso, the swing movement of the shoulder, the flexion and external rotation of the elbow, axial rotation of the upper limbs and driver's stature are the major factors affecting operation time. The average prediction error (APE) of the test buttons is 0.212s, and the APE of the new participants is 0.226s, which verifies the validity of the model. This study provides a new method for evaluating the convenience of automotive interior components.

Key words: automotive interior, operating convenience, operating posture, human motion tracking, statistical analysis, principal component regression
