ABSTRACT:
A method for controlling a damper clutch when a vehicle having an automatic transmission requires increased power. For example, when accelerating while driving uphill, the present invention disengages a damper clutch. This advantage is obtained by identifying a power increase region on the damper clutch engaged region of operation such that the damper clutch is disengaged. The method for controlling the damper clutch includes a step of generating engine signal indicative of engine rpms and throttle position. A control signal is developing such that control of the damper clutch is based upon the generated engine signals.
