The invention provides an intersection vehicle collision early warning method based on an Internet of Vehicles environment system. A remote service center firstly judges whether a first vehicle and a second vehicle are both in the same intersection range and both drive to the intersection at the current moment; if yes, the remote service center carries out prediction through the optimized first vehicle LSTM neural network to obtain a first vehicle prediction batch sample at the current moment, carries out prediction through the optimized second vehicle LSTM neural network to obtain a second vehicle prediction batch sample at the current moment, and carries out calculation according to a collision risk calculation model to obtain a collision risk time sequence; and then each sequence value of the collision risk time sequence is compared with a risk threshold value, and if the collision risk is greater than the risk threshold value, the remote service center controls the first vehicle and the second vehicle to slow down to avoid the collision risk. Compared with the prior art, the method has the advantages of long vehicle driving state prediction time delay, no need of manually setting vehicle driving parameters, scientific risk assessment mode and high early warning precision.

    本发明提出了一种基于车联网环境系统的交叉路口处车辆碰撞预警方法。远程服务中心首先判断当前时刻第一车辆、第二车辆是否均在同一路口范围内且均驶向路口;若是则远程服务中心通过优化后第一车辆LSTM神经网络预测得到当前时刻第一车辆预测批次样本,通过优化后第二车辆LSTM神经网络预测得到当前时刻第二车辆预测批次样本,并据此结合碰撞风险计算模型计算得到碰撞风险时间序列,然后将碰撞风险时间序列每个序列值与风险阈值比较,若碰撞风险大于风险阈值,则远程服务中心控制第一车辆和第二车辆减速行驶以规避碰撞风险。本发明与现有技术相比具有车辆行驶状态预测时延长,不需要人工设定车辆行驶参数,风险评估方式科学,预警精度高的优点。
