Abstract
A torque converter bump control system is provided. The system includes: a gain module that computes a torque converter gain based on a speed ratio; an increased gain module that computes an increased torque converter gain based on turbine speed; a blended gain module that computes a blended torque converter gain based on the torque converter gain, the increased torque converter gain, and a blend ratio; and a final gain module that selectively sets a final torque converter gain based on the speed ratio and commanded engine torque to at least one of the torque converter gain, the increased torque converter gain, and the blended torque converter gain and wherein engine torque is controlled based on the final torque converter gain.
