Abstract
An apparatus for controlling an automatically operated clutch assembly for use with a manually operated power transmission system of an automotive driveline, comprising a fluid operated actuating mechanism for driving the clutch assembly between fully coupled and fully uncoupled conditions. A valve arrangement for controlling the operation of the clutch actuating mechanism and an electric control circuit for controlling the valve arrangement on the basis of signals representative of the vehicle speed and opening degree of the throttle valve in the mixture supply system of the engine. The control circuit is operative to control the valve arrangement so that the clutch actuating mechanism drives the clutch assembly at stepwise varying velocities in response to variation in the throttle valve opening degree when the clutch assembly is in a partially coupled condition.
