In this paper an active knee bolster to actively control shock to the occupant legs is designed for a one-dimensional model of the lower extremity and is verified for the three-dimensional model on an crash simulation software. The one-dimensional model using the passive type of the knee bolster was validated for the three-dimensional model including the motion of the upper-body and the head. The feedback control system to follow a reference signal of the contact force between the knee and the instrument panel was implemented with the three-dimensional model. It was verified that the feedback control system designed is effective to suppress the femur load of the model near actual movement of the human body on the software.
