The invention discloses an active front bumper pedestrian protection plate and a control method thereof, and belongs to the technical field of automobile assembly, the active front bumper pedestrian protection plate comprises a front bumper pedestrian protection plate, a telescopic assembly, a forward-looking camera, a radar sensor, a wheel speed sensor, a central processing unit and a front end frame. The invention discloses an active front bumper pedestrian protection plate system and a control method thereof, and the method comprises the steps: detecting the distance between a front pedestrian and a vehicle front body, the advancing speed and direction in real time through a forward-looking camera, a radar sensor and a wheel speed sensor, and comparing with a neural network model builtat the beginning; before a pedestrian in front is detected and collides with the engine hood, the pedestrian protection plate automatically stretches out, the legs of the pedestrian are in collision contact with the pedestrian protection plate prior to the bumper, the pedestrian is prevented from being drawn into the vehicle and inclining towards the engine hood side, more buffer space is obtained, and harm of collision to the pedestrian is reduced.
本发明公开了一种主动式前保险杠行人护板及其控制方法,属于汽车装配技术领域,包括:前保险杠行人护板、伸缩总成、前视摄像头、雷达传感器、轮速传感器、中央处理器和前端框架。本发明公开了一种主动式前保险杠行人护板系统及其控制方法,通过前视摄像头、雷达传感器和轮速传感器实时检测前方行人与车前身的距离、行进速度和方向等,与初始时建立好的神经网络模型进行对比,当探测到前方行人并与之发生碰撞前,行人护板自动伸出,行人腿部优先于保险杠与行人护板发生碰撞接触,避免行人被卷入车下,并且使其向发动机罩侧发生倾斜,使其获得更多的缓冲空间,减少碰撞对行人产生的伤害。
