Abstract
A method is described for limiting a change in torque transmitted through a vehicle powertrain when in a predetermined range. Such a method minimizes transmission gear separation, or “clunk”. In one approach, the rate cf change of powertrain output is limited when powertrain output is near zero transmitted torque. The limitation is not used under other circumstances so as not to hinder driver performance.
