Abstract
Understanding the driver's driving posture demand is a crucial prerequisite for achieving adaptive layout decision-making in intelligent cockpits, including preferred joint angles and sensitive joint angles (acceptable posture changes). However, differences in anthropometric characteristics across racial populations and the lack of field research limit the application of relevant conclusions to the Chinese driver. This study conducted a field test, inviting 90 participants (60 males) with typical body characteristics of Chinese drivers to perform real driving tasks in three occupant package layouts (Sedan, SUV, and MPV). The study utilized motion capture and post-image marking methods to obtain six major joint angles in the sagittal plane of the human body. A two-way mixed ANOVA was employed to assess the impact of gender and OPL factors on preferred and sensitive joint angles. The results indicated that, for the preferred driving posture, both gender and OPL factors had significant main effects on elbow, trunk, and thigh angle. Regarding sensitive joint angles, gender significantly affected elbow and shoulder angles, while OPL significantly affected elbow, shoulder, hip, thigh, and calf angles. This study extensively explored the driving posture preferences of Chinese drivers of different genders in various typical passenger vehicles, providing crucial guidance for future dynamic layout adaptive decisions in automotive intelligent cockpit.
