Driver’s steering torque modeling based on lateral deviation and reaction torque

During high-speed driving, it can be experientially understood that it is a steering work during steering operation not by the steering angle but by the torque added to the steering wheel. This research uses the driver’s steering torque for the driver model construction. The proposed basic driver model considers both lateral deviation, as viewed in front of the vehicle, and reaction torque of steering axis for the model input. The driver’s steering torque during the lane change steering and a crosswind disturbance response by DS experiments are examined. Identified driver parameters by the proposed model are shown.
