Abstract:
A system for performing a shift operation of a multiple speed axle, comprising:a multiple-speed, automated change-gear mechanical transmission having an input shaft for connection to an engine and an output shaft for delivering rotation power to a multiple speed axle;wherein said multiple speed axle is selectively shiftable between a first speed range and a second speed range;a manually operated actuation device to initiate an axle shift of said multiple speed axle to selectively control said mechanical transmission by preventing said transmission from shifting gears during said axle shift between said first speed range and said second speed range; anda processing unit for receiving inputs indicative of operation of said actuation device and for processing said inputs according to predetermined logic rules for issuing command output signals to a non-manually controlled operator, wherein said controlled operator places said transmission in a hold mode when said axle shift is in progress, thereby preventing said transmission from shifting gears while said axle shift is being performed.
