Abstract
In recent years, a lot of research regarding steering assist controls has been studied with aims of reducing driver's steering workload and improving vehicle performance. Meanwhile, the performance as man-machine system may not always improve by intervention of the steering assist control because driver’s steering is essential. Therefore, the design of the system considering driver's characteristics is necessary. In this research, we designed the steering assist control by applying the optimal regulator for the closed-loop system including the driver, and control inputs of this system are both the steering angle and the steering torque in order to take driver's characteristics into account. In addition, we verified the control effects by using the driving simulator.
