The invention discloses a collision early warning method, a vehicle-mounted terminal and a related system. According to the scheme, firstly, driving data of a first vehicle at the current moment are obtained; calling a conditional random field (CRF) model to generate a trajectory prediction sequence of the first vehicle by using the driving data at the current moment and the driving data of the first vehicle at the historical moment; the track prediction sequence of the first vehicle and the identifier of the electronic fence where the first vehicle is located at the current moment are sent to the cloud computing service system; and finally, collision early warning information returned by the cloud computing service system is received. Different from the existing technical scheme depending on V2X, the technical scheme of the invention can realize collision early warning without depending on the V2X technology, thereby saving the collision early warning cost, getting rid of the protocol constraint, enhancing the flexibility and universality of technology implementation, and effectively improving the road traffic safety level and the driving safety performance.

    本申请公开了一种碰撞预警方法、车载终端和相关系统。该方案中,首先获取所述第一车辆当前时刻的行车数据;接着调用条件随机场CRF模型利用所述当前时刻的行车数据和所述第一车辆在历史时刻的行车数据,生成所述第一车辆的轨迹预测序列;其后向所述云计算服务系统发送所述第一车辆的轨迹预测序列和所述第一车辆当前时刻所处的电子围栏的标识;最后接收所述云计算服务系统返回的碰撞预警信息。区别于已有的依赖于V2X的技术方案,本申请技术方案不依赖于V2X技术即可实现碰撞预警,节省了碰撞预警成本,同时摆脱了协议约束,增强了技术实施的灵活性和普及性,有效提升了道路交通安全水平以及驾驶的安全性能。
