The objective of this work is to address the instability (inverse torque) caused by the tilt actuator in a narrow tilting vehicle by counterbalance it with a stability control system with gyro moment. A four-wheel narrow tilting vehicle was modeled in a multibody dynamics software to conduct a vehicle motion simulation with sharp steers, in order to investigate the gyro effects on the vehicle lateral acceleration (rollover resistance). From the results of the simulation, the critical steer angle when the first vehicle rollover happened without gyro was determined. At critical steer angle, the inner tire displacement from ground was relatively small (wheels were near to the ground) for vehicle with gyro, while vehicle without gyro experienced large displacement (overturn). Also, the vehicle inner wheel loads had become zero (wheels were lifting from the ground) during sharp steeis but was able to recover (the wheel loads) for vehicle with gyro, while vehicle without gyro failed to recover. By adding gyro into the control system, the vehicle had achieved higher lateral acceleration value then vehicle without gyro at the maximum steer angle without rollover. It was proven by the simulation that the stability control system with gyro moment had improved the rollover resistance of the narrow tilting vehicle.
