VEHICLE MODEL FOR ANALYZING CRASH PROBABILITY AND DECISION METHOD OF OPTIMAL LEAD TIME USING THE SAME

摘要

PURPOSE: A vehicle model for collision risk analysis and a read time decision method applied with the same are provided to draw an accurate result using three freedom degrees by designing four-wheel model. CONSTITUTION: A vehicle model for collision risk analysis comprises four-wheel model. A four-wheel model has three degree of freedoms. The four-wheel model is designed in considering of the vertical load transition and traversal load transition of the vehicles. The vertical load transition comprises the load transition between two axles by braking or accelerating. The traverse direction load transition comprises the load transition of the interval bent the outboard bent inboard. The traverse direction load transition analyzes the collision possibility in considering of front-wheel and rear wheel actuating force.
