摘要

Recently, the demand for unmanned vehicles to operate in challenging terrains has been increasing. Unmanned vehicles typically require fast driving in off-road, but excessive speed can lead to the vehicle overturning and damage. Therefore, it is important to define the average velocity for remote manned driving while maintaining vehicle stability. In this study, the vehicle model was developed using TruckMaker. To validate the vehicle model, computer simulations were conducted by using the same scenarios as driving experiments, comparing the dynamic characteristics of the actual vehicle and the vehicle model. The average relative error for the 3-axis translational and rotational behaviors of the vehicle model was 6.68 %. To access the state of the vehicle, driving stability metrics, namely RSM, LSM, VSM, and BSM, were defined. Real-time simulations were conducted using these driving metrics and the average velocity of remote driving, ensuring the safety of unmanned operations, has been calculated through simulation.
