摘要
A powertrain includes a torque generative device and a torque converter having an impeller, a turbine and a torque converter clutch. A method to control torque converter slip includes monitoring a reference slip and a turbine speed of the torque converter, determining a turbine torque based upon the reference slip and the turbine speed, determining a feed forward torque converter clutch pressure command based upon the turbine torque, a torque generative device torque, and a TCC gain, and controlling the torque converter clutch based upon the feed forward torque converter clutch pressure command.
