ABSTRACT
For the enhanced driving quality for human drivers, it is crucial to realize the harmonious transition between lateral and longitudinal motions. We have focused on G-Vectoring Control (GVC) which controls longitudinal acceleration in coordination with lateral acceleration. While the past researches applied brake control or electric motor control to decelerate the vehicle, the significance of the newly developed GVC is to use the high-response internal combustion engine to improve vehicle dynamics. Though the amount of engine torque reduction with the system is smaller than the engine brake, the system’s benefits were confirmed in various driving situations such as cornering and straight ahead driving. In this paper, after the system configuration is described, its control effects are evaluated through the field tests in objective and subjective aspects. Finally, it is emphasized that the GVC improves vehicle dynamics performance as human-vehicle closed loop system by modifying driver’s operation.
