4. DESCRIPTION OF THE INVENTION
A. PROBLEM ADDRESSED BY THE INVENTION: Describe the problem or need addressed by your invention. What problem does your invention solve, or what need does your invention fulfill?
The conventional automobile (Fig. 1) has an internal combustion engine (ICE) coupled to the wheels through a transmission. This requires the ICE be sized for maximum acceleration requirements which causes poor overall fuel mileage. Also the ICE is poorly matched to stop-and-go driving.

B. STATE OF THE ART: Describe how this problem or need has been addressed in the past. Identify any relevant literature or patents of which you are aware (including any EPRI reports or other prior written descriptions of the invention, any prior art patents or publications, and any presentations).

EPRI Report No. 10-55823: This report discusses additional research and methods employed in developing the current invention.
U.S. Patent No. 500,618: Issued to Henry Ford – Standard ICE system like that described above.
U.S. Patent No. 1,152,324: Issued to Eaton – Uses a supercharger to increase power and efficiency.
Other Relevant Developments: There are several article and publications relating to the improvement of ICE efficiency. For example, Publication 1 discusses ….
C. DETAILED DESCRIPTION: Provide a detailed description of what your invention is and how it works. What are the components (or steps if the invention is a method) of the invention and what is the function of each component? How do the components interact with each other? What are the novel aspects of your invention?
Include sketches, drawings, photographs, etc. to help illustrate your invention.
(Drawings may be attached on a separate sheet or included in the detailed description)
The invention has an ICE and an electric motor/generator (MG) coupled to the wheels through a planetary gearset. A battery and control electronics are coupled to the MG. This configuration allows optimum ICE cruise economy and battery charging at minimum penalty, while using the MG for stop-and-go driving and maximum acceleration.
The ICE (1) is sized only for cruise requirements. Max. output is approx. 50% of a conventional ICE for the same size vehicle.
The ICE (1) and MG (2) are both coupled to the wheels (3) through planetary gearset (4) such that the power supplied to the wheels (3) is the sum of the power input from the ICE (1) and MG (2).
A battery (5) and controller (6) are coupled to the MG. The controller charges the battery from the MG whenever the ICE output is sufficient for the load and/or the wheels are driving the vehicle (e.g. dynamic braking)
At speeds below a set threshold or when load exceeds ICE capability, the controller causes the MG to apply power to the wheels. The ICE is also shut off at low speeds.

D. RESULTS AND ADVANTAGES: What are the results and advantages of using your invention? How does it work differently from other devices or processes that accomplish the same purpose?
The invention is estimated to result in a 50% increase in fuel mileage and 20% decrease in tailpipe emissions. By coupling a an electric motor/generator, the ICE can be downsized for cruising speeds while the motor/generator carries the load for stop and go traffic situations. In addition, during slow driving speeds, the automobile can be powered by the motor/generator only, thereby eliminating the need to use the
ICE.
E. ALTERNATIVES: Are there any variations of your basic invention that accomplish the same purpose?
