A new driver assistance system is developed for longitudinal control in response not only to a preceding vehicle, but also to road curvature by combining "Adaptive Cruise Control (ACC)" with "Preview G-Vectoring Control" (PGVC) algorithm. This system controls the longitudinal acceleration by predicted and actual lateral motion of the vehicle like a trained driver. In this system, PGVC is improved by the dynamic parameter adjustment method based on estimated preceding vehicle information, which changes the PGVC parameter dynamically during driving through a curve, similar to the preceding vehicle. It is shown by driving tests on a test track that this adjustment method can avoid decelerating the vehicle by ACC for a safety time gap between ego and preceding vehicle during cornering. As the result, PGVC can manage both deceleration and acceleration during cornering and the longitudinal acceleration changes smoothly. This knowledge is useful to improve driver's comfort of an automated longitudinal acceleration control system.
