<p>Engine speed control during garage shift maneuvers of a transmission coupled, via a transmission input shaft, to a driven turbine of a hydrodynamic converter, the driven turbine fluidically coupled to a driving pump of the converter, the pump coupled to an engine output shaft, wherein engine output torque is controlled in response to a deviation in turbine acceleration away from a target turbine acceleration, to minimize rate of change in turbine acceleration (jerk) during the garage shift maneuver, so as to reject engine torque load changes that may result in undesirable engine speed variation.</p> |
