The invention designs an early warning method for preventing collision in a side blind area of a vehicle. The early warning method comprises the following steps: S1, acquiring real-time driving information of the vehicle; s2, when it is judged that the vehicle is in a steering state, an inner wheel difference area of the vehicle in the current state is calculated in real time according to the real-time driving information; s3, determining a blind area detection region ROI according to the inner wheel difference region and a detection range of an obstacle detection sensor; s4, according to the determined blind area detection region ROI, obstacle detection is carried out; and step S5, when it is determined that there is an obstacle in the blind area detection region ROI, performing lateral blind area anti-collision early warning in the steering direction. The method comprises the following steps: determining a first intersection point of a vehicle running speed direction horizontal vertical line or a vehicle head horizontal direction along a long line and an inner wheel difference area according to vehicle real-time driving information; and according to the connecting line between the first intersection point and the obstacle detection sensor, the blind area detection region ROI in the detection range can be determined in real time, and the technical effect of safety monitoring is achieved.
