The invention discloses a vehicle forward collision early warning system and method based on LTE-V2X, and the system comprises: a data obtaining module which is used for reading vehicle information through a GNSS data interface and a CAN data interface, and processing and packaging basic safety information of a vehicle; an inter-vehicle communication module which comprises LTE-V modules installedon the vehicle and other vehicles and is used for sending the basic safety information of the other vehicles to the vehicle, wherein the vehicle receives and processes the data sent by the other vehicles to obtain the basic safety information of the other vehicles; a data processing module which is used for calculating the collision time, the collision danger distance and the angle difference, isresponsible for realizing a vehicle forward collision early warning task and calculating and obtaining an early warning result, and is also responsible for providing a function of realizing a data storage function; and an early warning display module which is used for displaying the broadcast early warning condition and reminding a driver to avoid risks. The motion states of the vehicle and the target vehicle are obtained in real time through the LTE-V2X technology, and early warning is conducted on the potential danger under the conditions of low light, low visibility (rain, snow and fog weather) or invisibility (shielding or blind area) and the like.

    本发明公开了一种基于LTE‑V2X的车辆前向碰撞预警系统及方法,系统包括:数据获取模块,用于通过GNSS数据接口和CAN数据接口读取车辆信息,并处理封装成本车基本安全信息;车间通信模块,包括安装在本车和他车上LTE‑V模块,用于将他车基本安全信息发送给本车,本车接收并处理他车发送的数据以得到他车基本安全信息;数据处理模块,用于计算碰撞时间、碰撞危险距离和角度差,负责实现车辆前向碰撞预警任务,并计算得到预警结果,同时还负责提供实现数据存储函数的功能;预警显示模块,用于显示播报预警状况,提醒驾驶员规避风险。本发明利用LTE‑V2X技术进行实时获取本车和目标车辆运动状态,对潜在的如低光、低可视(雨雪雾天气)或不可视(遮挡或盲区)等条件下的危险进行预警。
