The invention provides an active automobile body control system comprising a vibration tester, an analog-digital converter, two front cameras, an image processing module, a controller and an electrically-controlled air pump; the vibration tester is used for outputting a vehicle vibration signal of analog electrical form; the analog-digital converter converts the vibration signal into a digital signal; the front cameras are mounted on a front windscreen and acquires road images; the image processing module is connected to the front cameras and converts the road images into concave-convex data of digital form; the concave-convex data comprise concave-convex positions and concave-convex depths; the controller is connected to the analog-digital converter and the image processing module and implements a virtual timer through software, the virtual timer averages vibration signals in a timing period, outputs a vibration level signal and outputs a vibration fine-tuning signal according to the concave-convex data; the electrically-controlled air pump is connected to four tire mounts, receives the vibration level signal and controls damping coefficients of four air pumps, and the damping coefficients of the air pumps are correspondingly finely adjusted according to vibration fine-tuning signal.
