<p>An apparatus and method for controlling the rate of engagement of a clutch in response to an indication provided by the driver, such as the depression of an accelerator pedal of the vehicle. The apparatus includes an electronic controller which initially determines a start rate as the minimum duty cycle which is required to modulate an engage valve in order to cause movement of a release bearing of the clutch in the engagement direction. The start rate is determined by initially moving the release bearing to the disengaged position. Then, the engage valve is incrementally modulated until the release bearing begins moving in the engaged direction from the disengaged position. When a predetermined amount of such movement has been detected, the electronic controller sets the start rate as the current duty cycle of the engage valve. The electronic controller is also responsive to an excessive amount of overshooting movement of the release bearing when attempting to position it in a desired position for reducing the start rate.</p> |
