Abstract
A transmission system selectively coupled to an engine crankshaft of an internal combustion engine arranged on a vehicle includes a transmission, a motor generator, a master clutch and a controller. The transmission includes an input shaft, a mainshaft, an output shaft and a countershaft offset from the input shaft. The countershaft is drivably connected to the first input shaft and the mainshaft. The motor generator is selectively coupled to the countershaft. The master clutch includes a driving portion connected to the engine crankshaft and a driven portion coupled to the transmission input shaft and adapted to frictionally engage the driving portion between open and closed positions. The controller selectively operates the transmission system in a first operating mode that includes defueling the engine while the vehicle is moving based on vehicle operating conditions and routes rotational energy from the output shaft, through the countershaft and into the motor generator.
