Abstract
A vehicle drive system for a vehicle including a first prime mover, a first prime mover driven transmission, and a rechargeable power source can be configured for reduced fuel consumption at idle. The vehicle drive system includes an electric motor in direct or indirect mechanical communication with the first prime mover, wherein the electric motor can receive power from the first prime mover driven transmission and can receive power from the first prime mover. The vehicle drive system also includes a control system. The control system causes the electric motor to rotate the first prime mover at a speed so that an electronic control module associated with the first prime mover does not cause fuel to be provided to the first prime mover while the vehicle is stopped, thereby reducing fuel consumption at idle for the vehicle.
