Partially automated lever-shifted mechanical transmission system

摘要

A partially automated transmission system (100) and method for controlling same is provided. The system includes a manually shifted splitter-type transmission (10) having a splitter section (14) and a manually shifted main section (12). The splitter section is controlled by a splitter actuator (116) under control from a system ECU (146). The operator is provided with a selector (120) for selecting upshifts and downshifts. Preferably, shifting in the upper group of ratios (A (9/10)) is fully automatic.
