Abstract

Improvements in a hybrid vehicle using an internal combustion engine and an electric propulsion, the improvement comprising the arrangement wherein there is a rear section which comprises a rear axle, wheels mounted on the rear axle, a platform mounted on the axle, and wherein the platform has a weight distribution whereby greater than 50% of the weight of the platform is located rearwardly of the rear axle and the platform is tilted with respect to the horizontal.

Claims

1. A method of operating a motor vehicle wherein the vehicle has an internal combustion engine and electrical propulsion means, said electrical propulsion means being associated with driving a first set of driving wheels and said internal combustion engine being associated with a second set of driving wheels, the method comprising the steps of using both said internal combustion engines and said electrical propulsion means for driving the vehicle from rest to a first predetermined speed, and using only said internal combustion engines when said vehicle has passed said predetermined speed.

10. The vehicle of claim 1 wherein said vehicle further includes an internal combustion engine, said vehicle being a hybrid vehicle.

2. In a hybrid vehicle having an internal combustion engine operative to drive a first set of driving wheels and electric propulsion means operative to drive a second set of driving wheels, the improvement comprising control means operative to supply power from said electrical propulsion means when said vehicle is accelerated from a position of rest up to a predetermined speed, and subsequently cut out of power from said electrical propulsion means when said predetermined speed has been exceeded.

3. The improvement of claim 2 wherein said electrical propulsion means comprises first and second electrical motors, each of said electrical motors being operatively coupled to a respective one of said second set of driving wheels.

4. The improvement of claim 3 wherein said second set of driving wheels comprises rear wheels of said vehicle.

5. The improvement of claim 2 wherein said batteries are operative to drive all accessories associated with the vehicle.

6. In a vehicle having a frame, a body secured to said frame, propulsion means, a front axle having wheels mounted thereon, the improvement wherein there is provided a rear section connected to said frame, said rear section comprising a rear axle, wheels mounted on said rear axle, a platform mounted on said axle, said platform having a weight distribution whereby greater than 50% of the weight of said platform is located rearwardly of said rear axle.

7. The vehicle of claim 6 wherein said vehicle includes electric propulsion means, said electric propulsion means including a plurality of batteries, said batteries being mounted on said platform.

8. The vehicle of claim 7 wherein said platform has a longitudinal axis extending from a front of said platform to a rear thereof, said longitudinal axis forming an angle with respect to horizontal of between 15°

and 17°

9. The vehicle of claim 7 wherein said platform has a weight distribution whereby the total difference between weight forward of said axle and a rear weight rearward of said axle is between 100 pounds and 400 pounds.
