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 ...

Ford Global Technologies, F G McKenzie, April 15, 2003: US06549838 (7 worldwide citation)

A control strategy and method for controlling friction element engagement and disengagement time for an automatic transmission when the transmission is operating at cold ambient temperatures. During drive-to-reverse or reverse-to-drive friction element engagements with power on, the strategy compens ...

Brian Michael O&apos Neil, Bradley Dean Riedle: Vehicle control method for vehicle having a torque converter. Ford Global Technologies, John D Russell, Allan J Lippa, August 13, 2002: US06434467 (1 worldwide citation)

A method is described for controlling a powertrain of a vehicle. In particular, the method attempts to minimize transmission gear separation, or “clunk”. Under some circumstances, it is determined whether torque converter output speed has become greater than torque converter input speed while the to ...

A method for controlling the capacity of friction clutches and brakes in a multiple-ratio vehicle transmission and for simultaneously establishing ratio shift point scheduling to effect a desired vehicle speed at which ratio changes occur while the vehicle is in a traction control mode. The method i ...
