Abstract

A reflective surface positioning apparatus (10) includes first locating device (21), second locating device (22), first utilizing device (51), and second utilizing device (52). The first locating device (21) locates part (32) of an occupant (30) of a vehicle (6) and produces a first location signal (41) indicative of the location of the part (32) of the vehicle occupant (30). The second locating device (22) locates an object (71) external to the vehicle (6) and produces a second location signal (42) indicative of the location of the external object (71). The first utilizing device (51) utilizes the first location signal (41) to cause positioning of a first reflective surface (61) to a first default position. The second utilizing device (52) utilizes the second location signal (42) to reposition the first reflective surface (61) to a first temporary position for providing a view of the external object (71) to the part (32) of the vehicle occupant (30) for a predetermined time interval. Then, the second utilizing device (52) returns the first reflective surface (61) to the first default position.

Claims

1. A reflective surface positioning apparatus comprising:

first transponder means for transmitting and receiving occupant locating signals for locating part of an occupant of a vehicle and for producing a first location signal indicative of a location of the part of the vehicle occupant;

second transponder means for transmitting and receiving object locating signals for locating an object external to the vehicle and for producing a second location signal indicative of a location of the external object;

first means for utilizing the first location signal to cause positioning of a first reflective surface to a first default position; and

second means for utilizing the second location signal to reposition the first reflective surface to a first temporary position for providing a view of the external object to the part of the vehicle occupant for a predetermined time interval and then returning the first reflective surface to the default position.

2. The apparatus as set forth in claim 1 further comprising:

third transmitter means for transmitting and receiving object locating signals for locating another object external to the vehicle and producing a third location signal indicative of a location of the other external object;

third means for utilizing the first location signal to cause positioning of a second reflective surface to a second default position; and

fourth means for utilizing the third location signal to reposition the second reflective surface to a second temporary position for providing a view of the other external object to the part of the vehicle occupant for a predetermined time interval and then returning the second reflective surface to the second default position.

3. The apparatus as set forth in claim 2 wherein the part of the vehicle occupant is the occupant'"'"'s eyes.

4. The apparatus as set forth in claim 3 further comprising:

fifth means for utilizing the first location signal to cause positioning of a third reflective surface to a third default position wherein the third reflective surface is a rear view mirror of the vehicle.

5. The apparatus as set forth in claim 1 wherein said first locating means includes three transducers disposed within a passenger compartment of the vehicle.

6. The apparatus as set forth in claim 1 further comprising a positioning mechanism for moving the first reflective surface from the first default position to the first temporary position.

7. The apparatus as set forth in claim 1 further comprising a driver alert device for communicating to the occupant of the vehicle that said apparatus has located an external object.

8. The apparatus as set forth in claim 1 wherein the second location signal indicates the presence of the external object in a predetermined area.

9. The apparatus as set forth in claim 1 wherein said first utilizing means and said second utilizing means are part of a controller disposed within a passenger compartment of the vehicle.

10. The apparatus as set forth in claim 1 wherein the first reflective surface is a driver'"'"'s side view mirror, the first temporary position providing a view to the occupant of a blind spot of the driver'"'"'s side view mirror.

11. A method for positioning at least one reflective surface on a vehicle, said method comprising the steps of:

transmitting and receiving occupant locating signals for locating a part of an occupant of the vehicle;

producing a first location signal indicative of a location of the part of the vehicle occupant;

transmitting and receiving object locating signals for locating an object external to the vehicle;

producing a second location signal indicative of a location of the external object;

utilizing the first location signal to cause positioning of a first reflective surface to a first default position;

utilizing the second location signal to reposition the first reflective surface to a first temporary position for providing a view of the external object to the part of the vehicle occupant for a predetermined time interval; and

returning the first reflective surface to the default position.

12. The method as set forth in claim 11 further comprising the steps of:

transmitting and receiving object locating signals for locating another object external to the vehicle;

producing a third location signal indicative of a location of the other external object;

utilizing the first location signal to cause positioning of a second reflective surface to a second default position;

utilizing the third location signal to reposition the second reflective surface to a second temporary position for providing a view of the other external object to the part of the vehicle occupant for a predetermined time interval; and

returning the second reflective surface to the second default position.

13. The method as set forth in claim 12 wherein the part of the vehicle occupant is the occupant'"'"'s eyes.

14. The method as set forth in claim 12 wherein the third location signal indicates the presence of the other external object in a predetermined area.

15. The method as set forth in claim 11 further comprising the steps of:

utilizing the first location signal to cause positioning of a third reflective surface to a third default position wherein the third reflective surface is a rear view mirror of the vehicle.

16. The method as set forth in claim 11 wherein the second location signal indicates the presence of the external object in a predetermined area.

17. The method as set forth in claim 11 wherein the step of locating an object external to the vehicle uses an ultrasonic sensor disposed at a rear corner of the vehicle.

18. The method as set forth in claim 11 wherein the first reflective surface remains in the first temporary position for about one second.

19. The method as set forth in claim 11 wherein the first reflective surface is a driver'"'"'s side rear view mirror disposed on the vehicle.

20. The method as set forth in claim 11 further comprising the step of:

activating the ignition of the vehicle in order to start said locating steps.
