The invention provides a child pedestrian protection device of an automobile. The child pedestrian protection device of the automobile is used for protecting a child pedestrian at the back of the automobile during backing-up. The child pedestrian protection device of the automobile comprises an engine electronic control unit, a supplemental restraint system (SRS) control unit, a camera, a pressure sensor and an SRS. The SRS control unit is connected with the engine electronic control unit. The camera and the pressure sensor are electrically connected with the engine electronic control unit respectively. The SRS is connected with the SRS control unit. The camera is arranged on a rear bumper of the automobile, the pressure sensor is arranged on the inner side of the rear bumper, and the SRS is arranged at a rear anti-collision beam of the automobile. During backing-up, when the rear of the automobile collides the child pedestrian, the pressure sensor senses that automobile collision force reaches a limit value capable of being born by the child pedestrian on the premise that the child pedestrian is not injured and the engine electronic control unit determines that an image in the camera is the child pedestrian, the engine electronic control unit sends a detonator signal to the SRS control unit, and the SRS control unit controls the SRS to be spread to protect the child.
