The invention provides an intelligent crosswind influence early-warning method based on an electric steering device. The intelligent crosswind influence early-warning method based on the electric steering device sequentially comprises the following steps that 1, an EPS system collects and writes in parameters comprising steering wheel moment, motor torque, a vehicle speed and a steering angle under the breezeless condition; 2, an EPS system early warning curved surface with steering resistance moment, the vehicle speed and the steering angle as three-dimensional coordinates is obtained, and the EPS system early warning curved surface is written into system debugging software in the later stage of development of the EPS system, wherein the steering resistance moment is equal to the sum of the steering wheel moment and the motor torque; 3, when a vehicle runs linearly at a high speed, signals of the parameter information comprising the steering wheel moment, the motor torque, a motor current, a vehicle speed and a steering angle are comprehensively processed, whether corresponding potential dangers that the vehicle is out of control, sideslips and rolls over will occur or not in a whole vehicle running environment is judged, corresponding coping actions are conducted, and intelligent early warning of the running state of the vehicle is conducted. By the adoption of the intelligent crosswind influence early-warning method based on an electric steering device, a driver can clearly judge the degree of the influence of crosswind on the stability of high-speed linear running of the vehicle and pay attention to the working conditions and the environment of the vehicle, and therefore active safety is improved.
