Specifically, set a safety distance selection button on the smart terminal, the user can click the safety distance selection button, and a window for setting the safety distance will pop up, and the user can set an appropriate safety distance for the vehicle according to their own needs. The distance is the safe distance beyond the outer contour of the vehicle, so that when other vehicles approach the safe distance range of the vehicle, an alarm signal can be sent to prompt the user to take remedial measures in time.

Then the user selects the seat position where the smart terminal is located directly behind the co-pilot of the vehicle, and finally the overall profile of the vehicle can be calculated based on the real-time position information and the relative position information of the seat position of the smart terminal located directly behind the co-pilot. Detailed positioning, and the detailed positioning information of the vehicle outline is displayed on the display interface of the smart terminal, which is intuitively presented to the user.

The present invention controls the vehicle speed of the vehicle by monitoring whether there is a monitoring signal ahead, and determines the stop position of the vehicle through the intensity of the monitoring signal, thereby controlling the stop position of the vehicle, which facilitates the traffic police to tell the driver when following the vehicle. Check for drunk driving. At the same time, in the positioning process, the detailed position information (ie, relative position information) of the user's terminal relative to the vehicle can be accurately located by locating the outline of the vehicle. In this way, the aforementioned real-time position information and relative position information can be combined , and then the entire outline of the vehicle is positioned in detail, so that the parking position is more accurate during emergency parking during the automatic car following process.

The implementations in the above examples can be further combined or replaced, and the examples are only descriptions of preferred embodiments of the present invention, and are not intended to limit the concept and scope of the present invention. Various changes and improvements to the technical solutions of the present invention made by those skilled in the art belong to the protection scope of the present invention.
