METHOD AND SYSTEM ESTABLISHING AN ENGINE SPEED FOR USE BY A CENTRIFUGAL CLUTCH CONTROL SYSTEM TO LAUNCH A VEHICLE

摘要

A control system/method controls a vehicular automated transmission system to modulate engagement of a centrifugal clutch. The automated transmission system including an internal combustion engine having an engine output member, a multiple speed change gear transmission having an input shaft, a centrifugal friction clutch for drivingly connecting said engine output member to said input shaft, a throttle responsive to manually requesting of a degree of engine fueling, and a system controller. The system controller has stored therein an engine speed limit used to facilitate vehicle launches.
