Brian Michael O&apos Neil, Bradley Dean Riedle, Dennis Allen Light, Michael John Cullen: Vehicle output control limiter. Ford Global Technologies, Allan J Lipps, John D Russell, April 8, 2003: US06543414 (19 worldwide citation)

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 tran ...

Ford Global Technologies, John D Russell, Allan J Lippa, John F Buckert, January 14, 2003: US06506140 (14 worldwide citation)

A vehicle control system is described for controlling a torque converter coupled to an engine. The controller engages the torque converter before negative powertrain output becomes less than a predetermined value. Such an approach allows for torque converter locking in the negative powertrain output ...
