Abstract
Techniques modeling and controlling a torque converter of a vehicle include accessing a look-up table relating (i) various K-factors of a turbine of the torque converter to (ii) various K-factors of an impeller of the torque converter, speed ratios of the torque converter, and torque ratios of the torque converter, calculating a K-factor of the turbine based on the set of parameters, determining a speed ratio and a torque ratio of the torque converter based on the calculated turbine K-factor using the look-up table, determining a target speed and a target torque for the impeller based on the determined speed and torque ratios of the torque converter, and controlling a torque generating system including the torque converter to achieve the target impeller speed and torque to thereby achieve the torque request at a driveline and mitigate or eliminate noise/vibration/harshness (NVH).
