Abstract

This article proposes a four-step method for simulating the car-entering movement. These four steps are: 1) build a corrected motion database, containing the motions in which the feet follow their measured trajectory, 2) identify and characterise the motion strategies of the car-entering movement, with each strategy being synthesised for a representative subject with known kinematic attributes, 3) model a segment of the predicted motion (e.g., the foot trajectories) using the motion strategies identified in Step 2, 4) compute the joint angles and simulate the car-entering movement of a new subject. The results of the motion simulation demonstrate a good correlation between the corrected and simulated joint angles, with the distance between these angles increasing with the distance between the simulated subject and the representative subject.
