The invention discloses an unmanned container truck front safety early warning method based on real-time positioning. The method comprises the following steps: carrying out plane gridding processing on a port high-precision map based on a Mercator coordinate system; based on the unmanned container truck real-time positioning and the vehicle head direction, generating a safety early warning area in front of the vehicle head according to a preset rule; coordinates of four vertexes of the unmanned container truck safety early warning area are converted into coordinates of a Mercator coordinate system, and corresponding grid data are obtained; and the grid state is checked and marked, and the unmanned container truck is controlled to run according to the current grid state. Compared with the prior art, the method is simple in logic, easy to implement and remarkable in unmanned driving safety guarantee effect. No additional equipment is added, and the implementation cost and period are low.
