ABSTRACT:
A method for closed loop vehicle dynamic control with a yaw rate controller, such as for example a TVD, utilizing a first understeer gradient for vehicle lateral accelerations at or below a vehicle lateral acceleration threshold and a second understeer gradient for vehicle lateral accelerations thereabove, wherein the vehicle lateral acceleration threshold defines a vehicle lateral acceleration transition point. A first desired vehicle yaw rate per the first understeer gradient is determined, and a second desired vehicle yaw rate per the second understeer gradient is determined, wherein the second desired vehicle yaw rate at the predetermined vehicle lateral acceleration transition point is calibrated to equal the first desired vehicle yaw rate at the predetermined vehicle lateral acceleration transition point so as to avoid any discontinuity therebetween.
