As the basis of determining the safe driving active risk avoidance control, the determination of the situation of the vehicle, and the fundamental of motive collision warning/collision avoidance （CW/CA） safety distance is one crucial part of the auto- ning strategy, an obstacle avoidance solution was propos sys ed tem. Based on the optimal trajectory plan- by means of longitudinal veloc and emergency lane change movement. The safety distance model based on emergency ity adjusting lane-change vehicle motion was put forward, and the influence from the different vehicle speed adjusting time on vehicle trajectory and safety distance was analyzed. The validity of the model was demonstrated by the simulation results for statistics obstacle avoidance situation.
