Propulsion system
First Claim
1. A propulsion system for a vehicle, comprising:
- a first traction drive system coupled to an engine and comprising a first drive motor, wherein the engine is operable to supply energy to the first drive motor to propel the vehicle; and
a second traction drive system comprising a second drive motor and a first energy storage device, wherein the second drive motor is operable to both supply energy to the first energy storage device and to receive energy from the first energy storage device,wherein the first drive motor is electrically coupled to only the first traction drive system.

Abstract
A propulsion system for a vehicle is provided. The propulsion system includes a first traction drive system and a second traction drive system. The first traction drive system includes a heat engine and a first drive motor. The heat engine supplies energy to the first drive motor to propel the vehicle. The second traction drive system includes a second drive motor and a first energy storage device. The second drive motor both supplies energy to the first energy storage device and receives energy from the first energy storage device. Also provided is a propulsion system for a vehicle that includes the first traction drive system and a propulsion means for supplying energy to a first energy storage device and for receiving energy from the first energy storage device.
