The invention provides a forward collision early warning method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a first motion state parameter of an own vehicle and a second motion state parameter of a target vehicle through determining the own vehicle and the forward target vehicle to be collided with the own vehicle, obtaining a first turning radius, a first safety distance and a second safety distance of a vehicle avoiding the target vehicle and an overlapping length of the vehicle and the target vehicle; obtaining a third safety distance through a third safety distance calculation formula; collision time is obtained through a collision time calculation formula; based on the preset conditions of the overlapping rate, the collision time, the third safety distance, the longitudinal distance, the fourth safety distance, the fifth safety distance and the sixth safety distance, the early warning signal of the early warning level corresponding to the preset conditions is output, the misjudgment behavior of frequent early warning or emergency braking in the non-emergency state is avoided, the attention of a driver is improved, and the driving safety is improved. And the potential safety hazard of driving is reduced.
本申请提供了一种前向碰撞的预警方法、装置、电子设备及存储介质,方法包括:通过确定自车与将要与自车发生碰撞的前向的目标车辆,获取自车的第一运动状态参数及目标车辆的第二运动状态参数,并获取避让目标车辆的自车的第一转弯半径、第一安全距离、第二安全距离以及自车与目标车辆的重叠长度;通过第三安全距离计算式获得第三安全距离;通过碰撞时间计算式获得碰撞时间;基于重叠率、碰撞时间、第三安全距离、纵向距离、第四安全距离、第五安全距离、第六安全距离的预设条件,输出与预设条件对应的预警级别的预警信号,避免了在非紧急状态下频繁进行预警或者紧急制动的误判行为,提升了驾驶员的注意力,进而降低了行车安全隐患。
