This invention provides automatic and reliable determination of the touch point of a clutch 20 controlled by an automatic clutch actuation controller 60. This invention determines the touch point upon power-up while idling the engine 10, with the transmission 30 in neutral and an input shaft brake 28 applied. The clutch actuation controller 60 gradually engages the clutch 20 so that the measured transmission input speed matches a reference speed signal preferably between 40% and 60% of the idle speed. If the actuation is slow enough, this reliably provides the degree of clutch engagement at a small torque matching the braking torque which is the touch point. If there is no previous knowledge of the touch point, the clutch 20 is applied at a fast rate and an approximate touch point is determined, then the clutch 20 is positioned below the approximate touch point and is again applied at a slow rate to more accurately ascertain the touch point. If there is previous knowledge of the touch point, the clutch 20 is positioned just below the old touch point and is applied at a slow rate to determine a new touch point. The new and old touch points may be combined to determine the updated touch point.
