Abstract

The vehicle operated in an electric highway system has an electric motor, at least one energy storage device, an on-board power pick up device, at least one coupler, at least one power meter, at least one on-board computer, an on-board part of a lateral location sensor, an on-board lateral position control mechanism, a longitudinal distance/speed sensor, and a longitudinal position control mechanism, and at least one communication device. The vehicle is able to operate and couple together with other vehicles automatically in the electrified lane of the electric highway system.

Claims

1. A vehicle operated on highways

including an electric motor, at least one energy storage means, and at least one coupler for physically coupling said vehicle with at least another one of said vehicle.

2. A vehicle operated on highways as defined on claim 1 wherein

said vehicle includes an on-board part of a lateral location sensor and a lateral position control means wherein

said lateral location sensor estimates deviation of center point of front end of said vehicle from imaginary centerline of said electrified lane, and

said lateral position control means tries to correct said deviation.

3. A vehicle operated on highways as defined in claim 1 wherein

said vehicle includes a longitudinal sensor, and

said vehicle includes a longitudinal position control means.

4. A vehicle operated on highways defined in claim 1 wherein

said coupler couples with another one of said coupler using magnetic force.

5. A vehicle operated on highways as defined in claim 1 wherein

said coupler couples with another one of said coupler using mechanical means.

6. A vehicle operated on highways as defined in claim 1 wherein

said vehicle has a different coupler height depending on a vehicle type.

7. A vehicle operated on highways as defined in claim 1 wherein

said coupler includes a pair of snubber assembly.

8. A vehicle operated on highways as defined in claim 1 wherein

said coupler includes a pair of coupling means.

9. A vehicle operated on highways as defined in claim 8 wherein

said coupling means includes means to generate magnetic field,

two of said couplers couple together by magnetic attraction.

10. A vehicle operated on highways as defined in claim 8 wherein

said coupling means includes a suction cup, and

two of said couplers couple together by suction.

11. A vehicle operated on highways as defined in claim 1 wherein

said coupler has a housing that encloses a coupling hook means and a coupling hook receiving bay disposed side by side, and

said coupling hook means is narrower at the tip, and is pivotably affixed to a pin,

said coupling hook receiving bay is wider at the opening end for easier entry of the hook means of the other said coupler, and has a switch at the farthest end from the opening.

12. A vehicle operated on highways as defined in claim 1 wherein said coupler has connection means for power cables.

13. A vehicle operated on highways as defined in claim 1 wherein said coupler has connection means for a communication cable.

14. A vehicle operated on highways as defined in claim 1 wherein

said highways have at least one electrified lane,

said electrified lane has a pavement surface,

said vehicle includes an on-board power pick up means assembly that includes a power pick up means assembly,

said power pick up means assembly is placed beneath the bottom of said vehicle,

said vehicle is equipped with a means to lift up and down said power pick up means assembly so that said power pick up means assembly can get closer to said pavement surface of said electrified lane when said vehicle is in said electrified lane, and

said power pick up means assembly is equipped with a means for sweeping possible debris on the electrified lane.

15. A vehicle operated on highways as defined in claim 1 wherein

said electrified lane has a pavement surface,

said vehicle includes an on-board power pick up means assembly that includes a power pick up means assembly,

said power pick up means assembly is placed beneath the bottom of said vehicle,

said vehicle is equipped with a means to lift up and down said power pick up means assembly so that said power pick up means assembly can get closer to said pavement surface of said electrified lane when said vehicle is in said electrified lane, and

said power pick up means assembly is equipped with wheels.

16. A vehicle operated on highways

said highways include at least one electrified lane and a roadside subsystem wherein

said roadside subsystem includes a pair of contact wires per said electrified lane,

said vehicle includes a power pick up means assembly,

said power pick up means includes at least a pair of sliding means,

each of said sliding means slidably contacts one of said contact wires,

each of said sliding means affixed to top of each of a pair of carriers made of a non-conductive material,

at least two pairs of horns made of a non-conductive material each of which horn is affixed to each side of said carrier,

said carriers are affixed to a support frame assembly,

a pantograph beam assembly is affixed to said support frame assembly at one end and affixed to the roof of said vehicle at the other end,

said two sliding means have a lateral gap such that even said contact wires fall lower than the normal level by accident, either of said contact wires will not touch both of said sliding means at the same time, and

said two sliding means are generally of the same length, which is shorter than spacing between said two contact wires and thus either of the sliding means will not touch said two contact wires at the same time.

17. A vehicle operated on highways as defined in claim 16 wherein

said vehicle includes at least one coupler, an on-board part of a lateral location sensor and a lateral position control means, and

said vehicle is able to operate in said electrified lane being coupled with at least one of said vehicle in said electrified lane while said vehicle is controlled by said lateral position control means.

18. A vehicle operated on highways as defined in claim 16 wherein

said highways have terminals along said highways, and

said vehicle is coupled or decoupled with said vehicle in said terminal.

19. A vehicle operated on highways as defined in claim 16 wherein

said vehicle includes a longitudinal position control means, and

said vehicle is able to couple and decouple with said vehicle on said highways while said vehicle is controlled automatically by said lateral position control means and said longitudinal position control means.

20. A vehicle operated on highways as defined in claim 16 wherein

said power pick up means assembly of said vehicle is folded down when not in use.
