Abstract
An automatic transmission on an automobile is combined with a friction clutch coupled between the output shaft of an engine and the input shaft of the automatic transmission. The friction clutch is controlled selectively for engagement and disengagement by an electric actuator. The electric actuator is controlled by a controller to engage the friction clutch in a feedback loop such that the rate of change of the rotational speed of the engine is zero when the power from the engine starts to be transmitted by the friction clutch to the automatic transmission.
