摘要：

为了提前预测车辆碰撞事故和降低碰撞事故发生概率，提出了基于车车通信的车辆防碰撞算法（VACA）。VACA根据自身和周围邻居车辆的北斗位置坐标，在水平和垂直两个方向上分别采用Kalman预测算法预测下一时刻的车辆行驶状态，采用数据预判断方法直接确定一定发生碰撞或不发生碰撞的情况。当不能直接判断时，则计算加速度可变下的安全距离，建立和求解碰撞状态预测模型，获得碰撞预测时间最小值。如果该最小值小于阈值，则发出报警信号提醒驾驶员。仿真结果表明，与基于车辆间通信的智能防碰撞报警模型（IVCWM）和车辆提前预警的防碰撞算法（ECWA）比较，VACA可提前发现碰撞情况，而且更准确，有一定的应用价值。

Abstract:

In order to improve the accuracy of predicting vehicle collision accidents and reduce the probability of collision accidents,vehicle anti-collision algorithm（VACA）based on vehicle to vehicle communication was proposed.According to Beidou location coordinates of vehicle itself and other vehicles in the vicinity,VACA used Kalman prediction algorithm to predict next vertical and horizontal locations of vehicles.VACA used data prejudge method to directly judge whether collision will happen.When it could't be directly judged,safe distance with variable acceleration was calculated,and collision state prediction model was established and solved,then minimum collision prediction time could be obtained.If the minimum time was less than threshold value,alarm signal would be sent to remind driver.Simulation results show that compared with IVCWM and ECWA,VACA can predict collision accident more accurately and has certain application value.

Key words: vehicle to vehicle communication, anti-collision, Beidou localization,warning
