A method for calculating a stability-ratio of a cross-wind and a method for controlling a steering angle of a vehicle are provided to adjust the steering angle according to the size and the direction of a cross-wind, thereby allowing a vehicle to drive more safely. The final speed, which is the actual progressing speed of a vehicle, is calculated by measuring the speeds and the directions of the vehicle and the cross-wind(S13). The yaw angle of a vehicle is calculated(S14). A force applied to the side surface of the vehicle is calculated by using the final speed and the yaw angle. The angular speed and steering angular speed through user manipulation are calculated, thereby calculating the angular speed caused by the cross-wind. The stability-ratio of the cross-wind is calculated by driving the angular speed resulting from the cross-wind by the force applied to the side surface of the vehicle(S30).
