ABSTRACT:
A continuously variable transmission mechanically coupled with an automated mechanical transmission is adjusted during a shifting process. At the completion of the shifting process, an engine mechanically coupled with the automated mechanical transmission is provided a fueling pulse. Additionally, the speed of an output shaft of the automated mechanical transmission is filtered by a second order variable time constant low pass filter.
