Abstract

This study presents control system design of a semi-active knee bolster in order to protect occupant lower extremities in frontal car crash. The semi-active knee bolster varies the damping coefficient of the knee bolster. The control system design of the semi-active knee bolster is based on a design method of an active knee bolster. LQI (Linear Quadratic Integration) control with an initial value compensation input is applied. We obtain an optimal reference signal of the contact force between the knees and the instrument panel by considering feedback characteristics of the closed loop system and the time constant of the semi-active actuator.
