摘要:
A multi-speed drive unit is provided for an electrically variable transmission having a variable-range output gear ratio for a motor vehicle. The variable-range output electrically variable transmission has improved final drive gear ratios that allow the motor to be operated in its desired efficiency and/or performance range during both city and highway vehicle operation. Further, the variable-range output electrically variable transmission allows for increased vehicle speeds during electric vehicle operation and provides for the use of the vehicle engine during reverse gear operation.
