Abstract

A mirror system for a tractor with an articulated trailer includes a mirror housing. The mirror housing is attached to the front end of the tractor on the passenger side. The mirror housing has a planar mirror. The planar mirror is adapted to move. The planar mirror moves allowing continuous observation of the passenger side rear corner of the trailer by a driver.

Claims

1. A mirror system for a trucking rig having a tractor and an articulated trailer comprising:

a mirror housing including a mirror movement motor, a planar mirror, and at least one of a convex mirror and a deformable mirror which can be controllably deformed between a planar shape and a convex shape; and

a mirror position controller for controlling said mirror movement motor to change the position of at least one of said mirrrors,

wherein said mirror housing is attached as far to the front of the tractor as possible, and

wherein the controlled movement of at least one of said mirrors allows continuous observation of a rear corner of the trailer.

2. The mirror system of claim 1, wherein said mirror housing is attached to a front fender of said tractor.

3. The mirror system of claim 1, wherein said mirror housing is attached to a front of a hood of said tractor.

4. The mirror system of claim 1, wherein said mirror movement motor is powered by said tractor.

5. The mirror system of claim 1, wherein said mirror housing further comprises a light source moveably controlled by said mirror position controller via said movement motor, and

wherein controlled movement of said at least one movable mirror and said movable light source allows continuous observation of the passenger side rear corner of the trailer in lighted or unlighted conditions.

6. The mirror system of claim 5, wherein said mirror housing further comprises a baffle which continuously blocks said light source from the vision of the driver.

7. The mirror system of claim 5, further comprising a positioner device located at a rear end of the trailer,

wherein said positioner device communicates with an antenna and a receiver connected to said mirror positioning controller via a transmitted signal, and

wherein positions of said at least one movable mirror and said movable light source are automatically adjusted by said mirror position controller via said mirror movement motor in response to said transmitted signal to track movement of a rear corner of the trailer and to allow continuous observation of the rear corner of the trailer by a driver in either lighted or unlighted conditions.

8. The mirror system of claim 7, wherein said positioner device is removably attached to the trailer.

9. The mirror system of claim 7, wherein said positioner device is powered by the tractor.

10. The mirror system of claim 1, wherein said mirror housing has a home position, and

said mirror position controller controls said mirror mount motor to move said movable mirror and said light source to said home position when said mirror system is deactivated.

11. The mirror system of claim 1, wherein said mirror system is in communication with said tractor, such that:

when said tractor is in a reverse gear or a low range forward gear said mirror system is activated; and

when said tractor is in neutral or a high range forward gear, said mirror system is deactivated.

12. The mirror system of claim 1, wherein said convex mirror is movable.

13. The mirror system of claim 12, wherein said mirror housing further includes a baffle, and

wherein said mirror position controller moves said convex mirror, said planar mirror, said light source and said baffle via said mirror movement motor in response to said signal so as to track the movement of the rear corner of the trailer and to allow observation of the rear corner of the trailer by the driver while backing in lighted or unlighted conditions.

14. The mirror system of claim 1, wherein said mirror housing includes said deformable mirror in which a shape of said deformable mirror is changed by a mirror shape changing motor.

15. The mirror system of claim 7, wherein said transmitted signal is a radio frequency encrypted with a 16 to 128 bit encryption.

16. The mirror system of claim 1, wherein said mirror housing is attached to a door of said tractor.

17. The mirror system of claim 1, further comprising a positioner device located at a rear end of the trailer,

wherein said position device communicates with an antenna connected to said mirror position controller via a transmitted signal, which is a radio frequency encrypted signal, and a position of said at least one moveable mirror is automatically adjusted by said mirror position controller via said mirror movement motor in response to said transmitted signal to track movement of the rear corner of the trailer, and

wherein said positioner device contains at least one illumination light source to illuminate the rear corner of the trailer to allow continuous observation of the rear corner of the trailer by a driver in either lighted or unlighted conditions.

18. The mirror system of claim 17, wherein said positioner device is removably attached to the trailer.

19. The mirror system of claim 17, wherein said positioner device is powered by the tractor.

20. The mirror system of claim 1, wherein said mirror movement motor moves the mirror housing so as to change the position of all of said mirrors, and

wherein the mirror movement controller automatically returns to a home position a predetermined time period after the mirror position controller causes said mirror movement motor to move said housing and is then deactivated.

21. The mirror system of claim 1, wherein the mirror housing includes only one said deformable mirror.

22. The mirror system of claim 21, wherein the mirror housing is attached to the door of the tractor.

23. The mirror system of claim 14, wherein said mirror movement motor and said mirror shape changing motor are powered by the tractor.

24. The mirror system of claim 23, further comprising a positioner device located at a rear end of the trailer,

wherein said positioner device communicates with an antenna and a receiver connected to said mirror positioning controller via a transmitted signal, which is a radio frequency encrypted signal, and wherein position and shape of said mirror are automatically adjusted by said mirror position controller via said mirror movement motor in response to said transmitted signal to track movement of the side rear corner of the trailer and to allow continuous observation of the rear corner of the trailer by a driver,

wherein said positioner device contains at least one illumination light source to illuminate the rear corner of the trailer.

25. The mirror system of claim 24, wherein said positioner device is removably attached to the trailer.

26. The mirror system of claim 24, wherein said positioner device is powered by a battery.

27. The mirror system of claim 24, wherein said positioner device is powered by the tractor.

28. The mirror system of claim 7, wherein said positioner device is powered by a battery.

29. The mirror system of claim 17, wherein said positioner device is powered by the battery.

30. The mirror system of claim 7, wherein said positioner device contains at least one illumination light source to illuminate the passenger side rear corner of the trailer.

31. The mirror system of claim 1, wherein said mirror housing is attached to a passenger side of the tractor.

32. The mirror system of claim 1, wherein said mirror housing is attached to a driver side of the tractor.
