Abstract

The automatic transmission of the invention comprises a mechanical countershaft transmission 11, gear synchronizer 22, 23 and clutch 12 which have been automated by the addition of electro-mechanical and pneumatic operators 15, 18, 21 and an analog and digital electronic control system 24. The electronic control system receives operator commands regarding the mode of transmission operation (either automatic or manual) and monitors throttle position, engine speed, transmission countershaft speed, drive shaft (vehicle) speed and rates of change of their speeds. By utilizing this information, the electronic control system 24 selects the optimum transmission gear ratio, effects synchronization of the selected transmission gear elements and controls clutch engagement and shut off of fuel supply according to a logic program. <IMAGE>
