Abstract

The invention discloses a bionic swarm intelligence-based real-time positioning navigation and motion control method for a moving vehicle and is used for solving the technical problem of lower reliability of the existing real-time positioning navigation and motion control method for the moving vehicle. The technical scheme is that the method comprises the steps of firstly selecting the vehicle and information nodes of known coordinates in a complex road as the positioning reference nodes, converting the equation set positioning and solving problem into the extreme value optimizing problem, and adopting a bionic swarm algorithm to solve the positioning coordinates. For the control on driving among multiple vehicles, a bionic swarm motion model is established to control the motion among the vehicles by establishing the bionic swarm behaviors, and the controllability on the real-time positioning and navigation and the motion control for the moving vehicle is improved. The real-time positioning navigation and motion control system for the moving vehicle is formed by a vehicle-mounted terminal module, a road information node module and a road traffic control center module. The three modules cooperatively work to realize the real-time positioning navigation and motion control on the moving vehicle.
