The embodiment of the invention discloses an unmanned vehicle emergency braking method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring and storing road condition information in a preset distance range in front of and behind a target unmanned vehicle in real time; when it is judged that communication between the power controller of the target unmanned vehicle and the automatic driving controller is interrupted, road condition information at the last moment is obtained; if the obstacle and/or the intersection influencing the driving of the target unmanned vehicle exist in the road condition information, acquiring the speed of the target unmanned vehicle, the position of the obstacle, the speed of the obstacle and the position of the intersection at the last moment; according to the target unmanned vehicle speed, the obstacle position, the obstacle speed and the intersection position, the deceleration and the driving direction of the target unmanned vehicle are determined. By adopting the scheme, the intersection information is acquired in real time, and the deceleration and the driving direction of the target unmanned vehicle are controlled according to the road condition information at the previous moment when the communication of the target unmanned vehicle is interrupted, so that the problems of vehicle rear-end collision and target unmanned vehicle dropping at the intersection are reduced.

    本发明实施例公开了一种无人车紧急制动方法、装置、电子设备及存储介质。该方法包括:实时获取并存储目标无人车前后方预设距离范围内的路况信息;当判断目标无人车的动力控制器与自动驾驶控制器通信中断时,获取上一时刻的路况信息;若所述路况信息中存在影响目标无人车行驶的障碍物和/或路口,则获取上一时刻的目标无人车速度、障碍物位置、障碍物速度以及路口位置;依据所述目标无人车速度、障碍物位置、障碍物速度以及路口位置,确定所述目标无人车的减速度以及行驶方向。采用本方案,实时获取路口信息,依据目标无人车通信中断时上一时刻的路况信息对目标无人车的减速度及行驶方向进行控制,以减少车辆追尾及目标无人车抛锚于路口的问题。
