The embodiment of the invention provides a motor vehicle emergency braking assisting method and device and a computer readable storage medium. The method comprises the following steps: receiving obstacle information around a motor vehicle; obtaining real-time coordinates of the obstacle relative to the motor vehicle through calculation; judging whether the obstacle is in a preset braking area of the motor vehicle or not according to the real-time coordinates and the real-time movement track of the motor vehicle, and marking the obstacle in the braking area as a target obstacle; dynamically tracking the target obstacle and updating the real-time coordinates of the target obstacle in real time according to the progress of dynamic tracking; judging whether the motor vehicle meets a preset braking condition or not according to the current real-time coordinates of the target obstacle in real time, and if yes, sending out a braking signal; and responding to the braking signal, calculating the braking deceleration a of the motor vehicle according to the current real-time coordinates of the target obstacle and the current speed of the motor vehicle, and sending the braking deceleration a to a braking system of the motor vehicle. The embodiment of the invention can accurately assist the driver in emergency braking of the motor vehicle.
本发明实施例提供一种机动车紧急制动辅助方法、装置及计算机可读存储介质,所述方法包括接收机动车周围的障碍物信息;计算获得障碍物相对机动车的实时坐标;根据实时坐标并结合机动车的实时运动轨迹判断障碍物是否处于机动车预设的制动区域内,将处于制动区域内的障碍物标记为目标障碍物;对目标障碍物进行动态跟踪并根据动态跟踪的进度实时更新目标障碍物的实时坐标;实时根据目标障碍物当前的实时坐标判断机动车是否满足预设的制动条件,若满足则发出制动信号;响应制动信号,根据目标障碍物当前的实时坐标和机动车的当前车速计算机动车的制动减速度a,并将制动减速度a发送至机动车的制动系统。本实施例能准确的辅助驾驶员紧急制动机动车。
