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 on a winding and slippery road. By intervention of the active steering control, the performance of the man-machine system may not always improve 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 operational characteristics into account. In addition, we verified the control effects by using the driving simulator.

Keywords: steering assistance; driver assistance systems; optimal control; simulation; driving simulator; driver modelling; driver characteristics; control ability; vehicle stability; winding roads; low frictional curves; advanced stability control; slippery roads; vehicle safety.
