摘　　要：针对传统最小安全距离的换道模型问题,即因忽视车辆之间的消息互通而缺乏主动性和灵活性,提出一种基于鱼群算法的车辆交叉换道模型。其出发点是将鱼群群体行为效应引入交通领域的车辆行驶控制中,同时分析了换道车周围车辆的运动状态,给出车辆之间各种可能的碰撞形式,构造了移动数学模型。在此基础上建立基于车车通信条件下的车辆集体行进、避障和换道的最小安全距离模型。实验结果表明,在一定条件下,利用人工鱼群算法收敛速度快的特点,可满足车辆协同行进和换道的实时性要求。This paper proposed a model of vehicle cross lane-changing based on fish swarm algorithm, to solve the problem of the traditional lane-changing models based on the minimum safety distance ignoring the communication between vehicles and lacking of initiative and flexibility. The point was to introduce the behavior effect of the fish group into the control of the traffic field, at the same time, it analyzed the movement state of the vehicle around the roadway, given the possible forms of collision between the vehicles, and constructed mobile mathematical model. On this basis, the minimum safety distance model of vehicle trave- ling, obstacle avoidance and lane changing based on vehicle communication was established. The experimental results show that using of the characteristics of the artificial fish algorithm convergence speed, thus can meet the real-time requirements of vehicle cooperative travel and lane changing under the condition.
