The invention is suitable for the technical field of automatic driving, and provides an automatic driving vehicle collision early warning method and system based on big data, and the method comprises the steps: obtaining the driving information of a target vehicle, obtaining the driving information of surrounding vehicles within a preset space-time range with the target vehicle, and forming an early warning data set through all the driving information; the driving information at least comprises identification information, position, speed and acceleration data of the vehicle; calculating the difference between the acceleration of all surrounding vehicles in the early warning data set and the reference acceleration; when the numerical value of one or more difference values is greater than a first acceleration threshold value, obtaining the position, speed and acceleration data of the vehicle corresponding to the one or more difference values, and combining the position, speed and acceleration data with the position, speed and acceleration data of the target vehicle to form a first data set; according to the method, a pre-judgment mechanism is added, corresponding data are further deeply processed according to requirements based on big data, collision early warning is achieved, and meanwhile endurance is taken into account.
本发明适用于自动驾驶技术领域,提供了一种基于大数据的自动驾驶汽车碰撞预警方法及系统,所述方法包括:获取目标车辆的行驶信息,获取与目标车辆处于预设时空范围内的周围车辆的行驶信息,所有行驶信息组成预警数据集;所述行驶信息至少包括:车辆的标识信息、位置、速度、加速度数据;计算预警数据集中所有周围车辆的加速度与参考加速度的差值;当有一个或多个所述差值的数值大于第一加速度阈值时,获取该一个或多个差值对应的车辆的位置、速度、加速度数据,并与目标车辆的位置、速度、加速度数据进行组合,构成第一数据集;本发明增加预判断机制,基于大数据,根据需求来进一步深度处理相应数据,实现碰撞预警,同时兼顾续航。
