In this paper, a speed control system for vehicle approaching, traveling, and coming out of a curve is investigated using simulation. In order to assist driver in ahcieving safer and more comfortable curve following performance, vehicle speed is controlled using the preview data of the road ahead, which is obtained from the GPS and Map or vision system. The control system is comprised of a method for determining a desired curve speed profile to help achieve the best cornering performance for an up-coming curve and regulating vehicle speed toward the desired speed. The lateral dynamics of vehicle is used for computing the desired speed for a curve. From the current vehicle speed and the desired speed profile, the acceleration profile for a curve ahead of the vehicle is computed. Then, the acceleration command is generated to slow the vehicle so the driver can achieve the optimal curve following. From the simulation studies, it is concluded that the system can potentially improve driver cornering performance.
