ABSTRACT:
In a control system for controlling engagement of a frictional element, such as a clutch, the derivative of the speed of an input member, such as a turbine shaft, of a transmission is calculated and compared to a target value. The difference, i.e., error, between the values is employed to control, hydraulically, the engagement of the frictional element. The control system operates the frictional element to reduce the error toward zero. This control routine operates only when the vehicle is idling.
