The invention relates to the technical field of pedestrian safety protection, in particular to an active intelligent pedestrian protection system which comprises a pedestrian protection air bag and an engine cover jacking device and further comprises a camera, a collision sensor, a vehicle speed sensor, an MCU and a controller ECU. The collision sensor is used for collecting pressure change information on a front bumper beam, and the vehicle speed sensor is used for collecting vehicle speed information of a vehicle in the running process. In combination with camera shooting pedestrian evaluation, whether a collided obstacle is a pedestrian or not is judged firstly, if the collided obstacle is judged to be the pedestrian, the controller ECU controls the pedestrian protection air bag or the engine cover jacking device to make a response, the purpose of pedestrian protection is achieved, and if the obstacle in front of the vehicle is judged not to be the pedestrian, the pedestrian protection air bag or the engine cover jacking device is controlled by the controller ECU to make a response. And if yes, the pedestrian protection air bag and the engine cover jacking device are controlled not to be detonated, so that the purpose of protecting the vehicle is achieved, and the maintenance cost can be reduced to the maximum extent.

    本发明涉及行人安全保护技术领域,具体涉及主动智能化行人保护系统,包括行人保护气囊以及发盖顶起器,还包括摄像头、碰撞传感器、车速传感器、MCU以及控制器ECU,所述摄像头用于采集车辆前方障碍物信息,所述碰撞传感器则用于采集前保险杠横梁上的压力变化信息,所述车速传感器则用于采集车辆在行驶中的车速信息。本发明通过结合摄像人行评估,先通过判断碰撞的障碍物是否为行人,若判断碰撞物为行人,控制器ECU会控制行人保护气囊或发盖顶起器作出反应,起到了对行人保护的目的,若判断车辆前方的障碍物不是行人时,则控制行人保护气囊和发盖顶起器均不进行起爆,以起到对车辆进行防护的目的,能够最大化的降低了维修成本。
