Abstract
An electronic control for energizing an electrically operated valve of a motor vehicle starting clutch at a level which compensates for performance variations of the valve and/or clutch so that the desired clutch engagement feel may be repeatably produced. The compensated energization level is formed by the combination of a principal term determined as a function of engine speed and a corrective, or vernier, term determined as a function of engine speed deviation from a reference engine speed. The reference engine speed is obtained by determining the desired steady state engine speed for the clutch engagement and applying thereto a time response characteristic that generally resembles that of the vehicle engine.
