Specifically, in real life, after a traffic accident occurs, the road traffic safety warning board should be placed in a lane where the accident occurs to remind a vehicle behind, so that the target position of the carrying trolley provided with the triangular warning board should be in the lane where the accident occurs, but in the path planning process, due to factors such as specific road conditions or map software, the planned path may leave the current lane, and other traffic accidents are caused. Therefore, the camera of the carrying trolley shoots the lane lines on the two sides of the moving direction, image information is transmitted back to the vehicle-mounted computer and/or the mobile phone in real time, the control equipment of a user controls the carrying trolley to maintain the lane where the current accident is located through image recognition, and meanwhile, the distance between the trolley and the lane lines is controlled to ensure safety, and the safety distance can be set manually or systematically, for example, the user sets that the carrying trolley must be more than 50 centimeters away from the lane lines on the two sides.

And step 260, moving according to the lane keeping control instruction fed back by the control equipment.

The carrying trolley obtains instructions for keeping the current lane and the safe distance of the lane line from a vehicle-mounted computer and/or a mobile phone of a user, and continues to move to the target position under the restriction of the instructions.
