Abstract

This paper investigates feasibility and performance of collision mitigation using an intelligent extending bumper system to absorb impact energy in vehicle frontal collisions. It is proposed to use a 1-1.5 m extending bumper supported by two hydraulic cylinders fixed to the longitudinal columns of the vehicle. A specially adapted fast response hydraulic flow control valve with a learning digital computer control is proposed. Simulation investigations revealed a maximum level of 9g deceleration could be achieved in a 30 mph collision.
