Embodiment Construction

[0035] A hybrid vehicle drive system according to several possible embodiments is presented. It is a feature of an exemplary embodiment of a hybrid vehicle drive system that the hybrid drive system may utilize an interface between a first prime mover and a transmission without using a PTO. It is another feature of one embodiment that the drive shaft may be powered solely by the first prime mover, the second prime mover, and accessories using the interface, or any combination thereof. A preferred embodiment incorporates a hydraulic system into the hybrid vehicle drive system to optimize energy storage and use. It should be noted that the term "motor" as used herein refers to a motor / generator or a motor / pump, and is not limited to devices that only perform motor operations.

[0036] According to one embodiment, inefficiency during regenerative braking is caused by removing the first prime mover from the system when the vehicle is braking. Yet another feature of an exemplary e...

Abstract

A vehicle drive system for a vehicle includes a first prime mover, a first prime mover driven transmission, and a rechargeable power source. The vehicle drive system includes an electric motor and 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 that causes the electric motor to rotate the first prime mover at a speed higher than an idle set point of the first prime mover while the vehicle is stopped, thereby reducing fuel consumption at idle per the vehicle.
