A proposal for collision mitigation is investigated in this paper. Two intelligently controlled hydraulic cylinders are proposed to be extended prior to collision and absorb impact energy upon engagement with the other body. Feasibility and performance of collision mitigation were investigated with a simulation of the collision dynamics. Various collision scenarios have been studied with view of predicting collision and proposing a pre-collision control strategy for activating the proposed hydraulic cylinders. For the purpose of this research a 0.5 m stroke hydraulic cylinder is used to act as an effective extension of the crash zone. Simulation results revealed a maximum level of 15g deceleration could be achieved in a 30 mph collision.
