Method and apparatus for selecting shift points in an automated mechanical transmission

摘要: A method and apparatus for selecting gear shift points wherein vehicle speed grade are monitored by :sensors which provide data is used to calculate acceleration adjusted compensate the effect of grade. gross weight value determined from value. Based on existing grade, horse power required sustain current GVW with zero calculated. Also determine rate loss during torque interrupt period in order predict engine new available at completion. If predicted above a predetermined minimum if completion equal or greater than maintain speed, permitted, otherwise not permitted measurements calculations necessary make point decision repeated. The may be reflect driver demand as represented throttle position.
