Abstract
A control method for operating an automated manual transmission system having a fuel-controlled engine, a multiple-speed change-gear transmission and a clutch drivingly interposed between the engine and an input shaft of the transmission is provided. The control method determines a rate of throttle change of a throttle pedal. The clutch is engaged at a first clutch engagement rate based on the rate of throttle change being greater than a threshold. The clutch is engaged at a second clutch engagement rate in a blended pedal mode that is proportional to an amount of throttle percentage engagement based on the rate of throttle change being less than the threshold. The first and second clutch engagement rates are distinct.
