This paper describes the performance of lateral mechanical guidance system for Dual Mode Truck. The vehicle stability is analyzed by 10 DOF vehicle dynamic model, where the coupling effect of the steering system with the hydraulic power steering device and the mechanical guidance system is considered. The unstable motion that is occurred in the field test with actual prototype Dual Mode Truck is analyzed with the simulation study. Both the simulation study and the field test show that the power steering device has large influence on vehicle stability and the unstable motion can be suppressed by cutting off the power steering device in the guideway. It is also shown that high speed operation of the Dual Mode Truck can be performed without power steering function in the exclusive guideway.
