A method for detecting a rough road by using an electronic stability program is provided to effectively detect the speed of each wheel based on the change of the wheel speed when a vehicle is driven on a rough road. An electronic stability program(ESP), which prohibits defect detection of a sensor mounted on the ESP when a road is rough, detects the speed of each wheel(S100). The number of wheels, which have a speed difference between a previous period and a present period of the detected wheel speed exceeding a preset value, is determined(S101,S102). The roughness of a road is determined according to the determined number of the wheels(S104). It is determined that the road is rough if the roughness of the road exceeds a preset(S105,S106). |
