A vehicle powertrain control system causes friction torque to be delivered to wheels at a generally constant value for a range of increasing requested friction torque values such that commanded powertrain torque values are reduced to a generally constant floor value. The range of increasing requested torque values is less than a requested powertrain torque value under foot off accelerator pedal and vehicle stop conditions.
