Driving all-terrain vehicles (ATVs) is a popular recreational activity. However, driving on an unpaved road poses risks even to an experienced ATV driver. In this work, a six-degree of-freedom ATV motion simulator is designed. A motion platform, which provides a safe and comfortable environment for drivers to develop their skill over an extended period, is used to simulate the dynamics of a passive ATV suspension. The proposed simulator provides a virtual ATV driving environment that includes rough terrains that drivers may feel uncomfortable with even in the simulated environment. Importantly, the simulator optimizes the dynamic parameters of the suspension system, enabling ATV drivers to experience the driving activity more comfortably yet realistically. A comparison between simulation results and experimental results indicates that the simulator has high adaptability.
