Abstract:
1. A power system for a motor vehicle comprising: an internal combustion engine; an auxiliary power unit; a transmission for distributing power from the internal combustion engine; a power takeoff operation unit coupled with the transmission for diversion of power to a power takeoff system; a selective coupling element from an auxiliary engine to the power takeoff operation system; a clutch for mechanically coupling work from the internal combustion engine to the transmission, the clutch having a position allowing reverse transmission of mechanical energy from the auxiliary engine, the selective coupling element and the power take operation system for cranking the internal combustion engine; a starter signal source; and a controller system responsive to the starter signal for determining clutch position and whether the auxiliary engine is on and the internal combustion engine is off for coupling mechanical output from the auxiliary engine to the power takeoff operation unit.
