Prediction of lower-limb movements of clutch pedal operation from an existing motion database


Type de document
Résumé / Abstract
Pedals are one of the important controls used in vehicles. Compared to hand controls, foot controls often restrict the posture of the user, and an inappropriate pedal design may contribute to muscle fatigue and cause discomfort for drivers. It is very important for engineers to be able to simulate realistic Iower Iimb movements during a pedal control operation using a digital human model at the early stage of its design. Recently, the low-Iimb movements of clutch pedal operations were investigated experimentally (Wang et al, 2000), and a database was then created. In this paper, an inverse kinematics algorithm will be proposed to predict Iower-Iimb pedal operation motion from the existing motion database. Emphasis will be put on how to keep a predicted motion similar to experimental observation and to satisfy the constraints imposed by the task and the environment at the same time.
