The invention relates to a front bumper upper portion pedestrian protection system which comprises a front bumper upper portion skin, a front bumper upper supporting plate and headlamps, the front bumper upper supporting plate is arranged in the width direction of a vehicle body, the two ends of the front bumper upper supporting plate are connected to the two headlamps respectively, and the front bumper upper portion skin covers the front bumper upper supporting plate. A first collision buffering cavity is formed between the front bumper upper portion skin and the front bumper upper supporting plate, a second collision buffering cavity is formed between the front bumper upper supporting plate and the headlamp, and when an automobile is normally used, the front bumper upper portion pedestrian protection system can provide a proper supporting effect; when an automobile collides with a pedestrian, impact force on the thighs (pelvis) of an adult and the head of a child in the collision process can be buffered through structural deformation and collapse energy absorption, so that harm to the pedestrian is reduced, and the invention further provides the automobile with the protection system for the pedestrian on the upper portion of the front bumper.
