In automotive manufacturers and researchers, the lateral control systems for vehicle motion play an important role. To prevent spinning and drifting out of vehicles from the road, vehicle spinning control systems must be stabilized in secured direction. The variables of tire-road friction coefficient are more effective to provide lateral force for spinning control systems and the vehicle can be able to follow the required trajectory. Also, this work has main purpose to study the dynamic model of unmanned all-terrain vehicle (ATV) and some variables, which affect to vehicle motion for control system. For this work, the unmanned ATV’s system is analyzed by using Matlab-Simulink. The variables in simulation can be adjusted to study the effect to output variables of unmanned ATV.
