摘要

A control for enhanced shifting in a computer (48) -assisted vehicular compound transmission system having a having a main section (16A) shifted by a manually operated shift lever (31). The system is controlled as a function of current main section engaged or neutral condition sensed as function of shift lever vertical position in an H-type shift pattern. A position sensor (160) is provided for sensing the position of the shift lever in the shift pattern. Logic is provided to vary, as a function of vehicle operating conditions, the location/width of the bands of vertical positions (202/204) considered to be indicative of a main section neutral condition.
