In this study, a ‘hybrid stability-control’ system based on two concepts – G-Vectoring Control (GVC) and direct-yaw-moment control (DYC) – was developed. This system controls deceleration according to the information on vehicle lateral jerk and yaw moment according to the information on vehicle sideslip. It reduces the tendency to understeer by applying deceleration via GVC and reduces the tendency to oversteer by adding yaw moment via DYC. The tests with a vehicle fitted with this new GVC/DYC hybrid control confirmed that understeer can be reduced significantly more than that possible with conventional DYC only. It is concluded that this greater understeer reduction is a result of GVC preventing understeer prior to the skidding of the vehicle.
