  • Method for reducing driveline disturbances by controlling torque converter clutch application
    Patent number: 5484353
    Abstract: A torque converter clutch control reduces or eliminates undesirable driveline disturbances through throttle position or load based criteria. A region of vehicle operation delineated by vehicle speed prone to driveline disturbances during certain vehicle operating conditions is used to predict such disturbances and disengage the torque converter clutch. Disturbances are cumulated and upon reaching a predetermined number of events the control substitutes certain torque converter clutch apply/release patterns to further reduce such disturbances.
