Abstract

An electrical passenger car, the electrical passenger car including: at least two electrically driven motors; speed control electronics; and wheels, where the wheels include a front wheel and a back wheel, where the back wheel radius is at least 20% greater than the front wheel radius, where the speed control electronics control the at least two electrically driven motors to provide a greater torque to the front wheel than to the back wheel, and where the speed control electronics control the at least two electrically driven motors to provide a greater torque to the back wheel than to the front wheel.

First claim

We claim:

1. An electrical passenger car, the electrical passenger car comprising:
at least two electrically driven motors;
speed control electronics; and
wheels,
wherein said wheels comprise a front wheel and a back wheel,
wherein said back wheel radius is at least 20% greater than said front wheel radius,
wherein said speed control electronics control said at least two electrically driven motors to provide a greater torque to said front wheel than to said back wheel, or
wherein said speed control electronics control said at least two electrically driven motors to provide a greater torque to said back wheel than to said front wheel.

2. The electrical passenger car according to claim 1 ,
wherein said electrical passenger car is designed to travel for a greater distance for the same axial to wheel friction energy loss than a similar electrical passenger car having wheels of a smaller radius.

3. The electrical passenger car according to claim 1 , further comprising:
electrical steering,
wherein said wheels comprise a first front wheel and a second front wheel,
wherein said electrical steering comprises independently controlling a first speed of said first front wheel and independently controlling a second speed of said second front wheel.

4. The electrical passenger car according to claim 1 ,
wherein said speed control electronics are controlled to provide greater braking and recharging to said back wheel than to said front wheel.

5. The electrical passenger car according to claim 1 ,
wherein said back wheel radius is at least 3 times greater than a width of said back wheel.

6. The electrical passenger car according to claim 1 ,
wherein said back wheel radius is greater than 90 cm.

7. The electrical passenger car according to claim 1 ,
wherein said electrical passenger car comprises a center of gravity, and
wherein a distance from said center of gravity distance to a road surface is 10% longer or shorter than said back wheel radius.

8. An electrical passenger car, the electrical passenger car comprising:
at least two electrically driven motors;
speed control electronics; and
wheels,
wherein said wheels comprise a front wheel and a back wheel,
wherein said back wheel radius is at least 20% greater than said front wheel radius, and
wherein said speed control electronics are controlled to provide greater braking and recharging to said back wheel than to said front wheel.

9. The electrical passenger car according to claim 8 ,
wherein said electrical passenger car is designed to travel for a greater distance for the same axial to wheel friction energy loss than a similar electrical passenger car having wheels of a smaller radius.

10. The electrical passenger car according to claim 8 , further comprising:
electrical steering,
wherein said wheels comprise a first front wheel and a second front wheel,
wherein said electrical steering comprises independently controlling a first speed of said first front wheel and independently controlling a second speed of said second front wheel.

11. The electrical passenger car according to claim 8 ,
wherein said speed control electronics control said at least two electrically driven motors to provide a greater torque to said front wheel than to said back wheel.

12. The electrical passenger car according to claim 8 ,
wherein said back wheel radius is at least 3 times greater than a width of said back wheel.

13. The electrical passenger car according to claim 8 ,
wherein said back wheel radius is greater than 90 cm.

14. The electrical passenger car according to claim 8 ,
wherein said electrical passenger car comprises a center of gravity, and
wherein a distance from said center of gravity distance to a road surface is 10% longer or shorter than said back wheel radius.

15. An electrical passenger car, the electrical passenger car comprising:
at least two electrically driven motors;
speed control electronics; and
wheels,
wherein said wheels comprise a front wheel and a back wheel,
wherein said back wheel radius is at least 20% smaller than said front wheel radius,
wherein said speed control electronics control said at least two electrically driven motors to provide a greater torque to said front wheel than to said back wheel, or
wherein said speed control electronics control said at least two electrically driven motors to provide a greater torque to said back wheel than to said front wheel.

16. The electrical passenger car according to claim 15 ,
wherein said electrical passenger car is designed to travel for a greater distance for the same axial to wheel friction energy loss than a similar electrical passenger car having wheels of a smaller radius.

17. The electrical passenger car according to claim 15 , further comprising:
electrical steering,
wherein said wheels comprise a first front wheel and a second front wheel,
wherein said electrical steering comprises independently controlling a first speed of said first front wheel and independently controlling a second speed of said second front wheel.

18. The electrical passenger car according to claim 15 ,
wherein said speed control electronics are controlled to provide greater braking and recharging to said back wheel than to said front wheel.

19. The electrical passenger car according to claim 15 ,
wherein said back wheel radius is at least 3 times greater than a width of said back wheel.

20. The electrical passenger car according to claim 15 ,
wherein said electrical passenger car comprises a center of gravity, and
wherein a distance from said center of gravity distance to a road surface is 10% longer or shorter than said back wheel radius.
