摘要 行为决策系统在很大程度上反映了自动驾驶汽车的智能化水平,作为自动驾驶汽车的大脑,行为决策系统决定了自动驾驶车辆的可行性和安全性。文章基于行车效率与行车安全对高速自动驾驶汽车的智能决策进行了研究。通过引入能效函数与动态子区域监测系统,实时计算本车道与相邻车道的行车能效值以及本车与周边车辆的碰撞风险,并基于此确定最优驾驶策略,一定程度上提升了自动驾驶车辆的行车效率与安全。 The Principal objective of this work is to study intelligent decision for highway automated driving.The Proposed framework develops,implements and tests a framework for intelligent decision based on efficiency and safety.It considers the vehicle-around situation based on a state space with eight subareas,which makes the real-time assessment for current traffic situation possible and efficiency.Based on the proposed framework,realistic simulation has also been carried out and presented.Results show that the intelligent decision based on the proposed framework is feasible and effective.
