The invention discloses an irradiation direction adjusting method for an automobile headlamp on a bumpy road. A speed sensor is arranged on a front wheel axle of an automobile, after the speed of the front wheel axle of the automobile in the vertical direction is obtained, the speed is compared with a preset speed threshold value, if the speed of the front wheel axle of the automobile in the vertical direction is larger than the preset speed threshold value, the jolting angle of the automobile is calculated according to the sampling clearance of the speed sensor, the distance between the front wheel axle of the automobile and the center of the automobile and the speed of the front wheel axle of the automobile in the vertical direction, then the automobile headlamp is adjusted in the direction opposite to the jolting direction of the automobile, and the adjusted angle is theta. The irradiation direction adjusting method is simple in design and convenient to use, when the automobile runs on the bumpy road, an optical axis of the headlamp is made to restore to the original horizontal state to the greatest extent, a blind area is avoided, and driving is safer.
