Abstract
A control system/control method for controlling the jaw clutch engagement and at least partially automated multiple speed change gear mechanical transmission (10) is provided. The control includes a central processing unit (106) for receiving signals indicative of transmission input shaft (16) speed, transmission output shaft (90) speed and of a selected ratio to be engaged. The control unit initiates/permits engagement of the jaw clutch members associated with the selected ratio upon sensing that the rotational speed of the input shaft falls within calculated synchronous window. The control unit senses vehicle start from stop conditions and/or degraded clutch operation during vehicle start from stop conditions and responds thereto by enlarging the synchronous window.
