Electronic transmission control and method therefor

摘要: A control for the automatic shifting of a multi-ratio power transmission. memory is provided and programmed with optimum vehicle speed shift points upshift downshift from each gear range. The actual periodically sampled, time it is, such compared which transmission in to see if should be made. If determined sample that an made, then higher gears are examined reference find upshifted, i.e., just above highest having point less than sampled speed. Having found gear, shifted thereto. Correspondingly, made (or can event forced condition), lower below lowest At any time, operator may set range as so will not beyond gear.
