The invention discloses a multi-information fusion adaptive cruise control system and a multi-information fusion adaptive cruise control method. A camera acquires images to identify the road speed limit of a current road section; a millimeter-wave radar detects and obtains the relative distance and the relative speed between a current vehicle and a front target vehicle; a positioning system detects the current position of the current vehicle, and obtains the road curvature; a driving control instrument collects the current speed of the current vehicle; and a self-adaptive cruise controller receives the road speed limit information to determine the road speed limit of the current vehicle in the current position, performs calculation according to the current speed of the current vehicle to obtain an expected vehicle distance, and performs adaptive cruise control according to the expected vehicle distance, the absolute speed, the relative distance and the lane speed limit so as to controlthe vehicle speed of the current vehicle. The adaptive cruise control is fused with information such as the camera, the millimeter-wave radar, a map and a positioning system, a driver is assisted todrive within a proper speed range, and the road traffic safety is improved.
