- Abstract
- The power steering system for vehicles is becoming essential for supporting the steering efforts of the drivers, especially for the parking lot maneuver. Although hydraulic power steering has been widely used for years, its efficiency is not high enough. The problems associated with a hydraulic power steering system can be solved by a motor driven power steering (MDPS) system. In this study, a dynamic model and a control algorithm for the ball screw type of MDPS system have been derived and analyzed by using the method of discrete modeling technology. To improve steering feel and power steering characteristics, two derivative gains are added to the conventional power boosting control algorithm. Through simulations, the effects of the control gain on the steering angle gain were verified in the frequency domain. The steering returnability and steering torque phase lag in on-center handling test were also evaluated in the time domain.
