First, the structure of a virtual-rail train-like vehicle with large capacity and self-guidance ability is proposed,which combines the structural advantage of rail train and traditional cars.Then the basic parameters and power drive scheme of the virtual-rail train-like vehicle are designed to realize its flexible movement function in complex urban space.Furthermore, a differential steering control method for this kind of virtual-rail train-like vehicle is proposed to reduce the driving difficulty and realize its automatic driving function. Finally, a theoretical prototype of the virtual rail train is built and the effect of the differential steering control method of the virtual-rail train-like vehicle is tested. The experimental results show that the virtual-rail train-like vehicle control method based on all-wheel differential steering can achieve the control of the vehicle to travel along target route, and the proposed virtual-rail train-like vehicle with large capacity and automatic driving function can run on urban roads with limited space, providing references for the development of urban public transport vehicle.
