路面入力の影響を考慮した操舵トルクの再現手法の検討

抄録

Vehicle motion is realized through forces generated between the tires and the road surface and is closely related to the road surface. Steering torque generated at the steering wheel due to forces from the road surface and friction in the mechanical system is important information for understanding road surface conditions and driving conditions. In this study, we attempted to reproduce the steering torque characteristics in a simulator that takes road surface inputs into account. The force that the tires receive from the road surface during driving was calculated. This force was input to a multibody model of the steering system, and the resulting steering torque was output by the simulator. The simulator's reproducibility was evaluated by comparing the results of the simulator with the results of the model calculations.
