The invention discloses a road condition recognition control system and method for a vehicle, and relates to the technical field of vehicle intellectualization. A map engine module; a road condition identification unit; four air springs, each air spring is provided with a height sensor, and all the height sensors are connected to a vehicle-mounted ECU; the air storage tank is respectively connected to the four air springs through four pipelines; a vehicle-mounted ECU obtains position information and height information of height limiting objects on the way in advance through a map engine module, and distance information and height information of height limiting objects in front of a vehicle are recognized in real time through a road condition recognition unit; and the vehicle-mounted ECU automatically adjusts the four air springs through the height sensor to eliminate the pitch angle of the chassis of the vehicle body when the weight distribution in front of and behind the vehicle is not uniform or the vehicle goes uphill and downhill. According to the road condition recognition control system and method, the pitch angle of the vehicle body can be eliminated in real time, the trafficability is judged in two steps, and accuracy and safety are achieved.
