Abstract
This study seeks to design a lane keeping controller for motorcycles and to evaluate it by using a rider control model. We applied the optimal control theory to evaluate a lateral displacement at a virtual point ahead of the vehicle. By examining the computer simulation with the rider-in-the-loop system consisting of the motorcycle, the controller, and the rider control model, good lane following performance is achieved without interference between the control input and the rider's input. In addition, the virtual point regulator corresponds to not only the steering torque disturbance but also the lateral force disturbance by choosing the distance to the virtual point.
