Abstract:
A compound-input is provided for an electrically variable transmission for a motor vehicle. The compound-input electrically variable transmission has improved input gear ratios that allow the vehicle engine to be operated in its desired efficiency and/or performance range during both city and highway vehicle operation. Further, the multi-speed input electrically variable transmission provides an input brake without the need for a dedicated input brake clutch or braking mechanism and incorporates a reverse gear for reverse operation.
