Free control behavior is one of the most fundamental characteristics for vehicle high-speed stability. This paper presents a discussion of the effects of a steering system on the free control stability, especially with steering damping. It is analyzed by means of the root loci obtained from fundamental equations of free control motion. As a result, for cornering stiffness, the improvement direction for stability is reversed due to the amount of steering damping. Furthermore, the equations of motion are modified to describe the gyroscopic moment of rotating wheels by which the steering system interferes with rolling motion. The results show the effects of damping and inertia of a steering system, as well as cornering stiffness of front and rear wheels on the free control stability. In addition, the results show that the power steering assist characteristics and rotating wheel gyroscopic moment have an important effect on the stability.
