Abstract

A mirror system for a vehicle includes at least one exterior mirror having a reflective element, a housing for the reflective element, a positioning device for selectively positioning the reflective element, and a light for emitting light generally downwardly from the mirror housing on an area adjacent the side of the vehicle. A control is responsive to the vehicle reverse gear selector being in reverse gear for causing the positioning device to position the reflective element to a downwardly tilted position, wherein the driver can view an area adjacent a side of the vehicle. The control actuates the light when the reflective element is in the downwardly tilted position in order to illuminate objects in that area. In a preferred embodiment, the control actuates the light through a lockout circuit which normally allows the light to be activated only when the vehicle is not operating. The control includes an override for the lockout circuit which allows the light to be activated even when the vehicle is operating when, and only when, reverse gear is selected.

Claims

1. An illuminated power tilt exterior mirror system for a vehicle having a reverse gear selector, comprising:

an exterior mirror assembly having a reflective element, a housing for said reflective element, and a positioning device for selectively positioning said reflective element about a horizontal axis to a power tilt position;

said positioning device further being capable of positioning said reflective element about a vertical axis and said horizontal axis in order to provide vision directly rearwardly of the vehicle during normal use on a highway;

a tilt control that is responsive to said vehicle reverse gear selector being placed in a reverse gear mode for causing said positioning device to position said reflective element about said horizontal axis to said power tilt position to view an area adjacent a side of the vehicle; and

a light for emitting light generally downwardly from said housing on an area adjacent said side of said vehicle;

wherein said tilt control actuates said light as a function of said reflective element being in said power tilt position and said reverse gear selector being placed in said reverse gear mode in order to illuminate objects in said area.

2. The illuminated power tilt exterior mirror system of claim 1 wherein said positioning device comprises an electrically powered actuator.

3. The illuminated power tilt exterior mirror system of claim 2 wherein said system comprises a memory and a control operable to store data indicative of multiple positions of said reflective element in said memory and to retrieve data from said memory in order to allow said reflective element to be selectively positioned by said positioning device to one or more predetermined positions.

4. The illuminated power tilt exterior mirror system of claim 3 wherein said power tilt position of said reflective element is stored in said memory.

5. The illuminated power tilt exterior mirror system of claim 1 wherein said reflective element is downwardly tilted at an angle of at least approximately four degrees from vertical about said horizontal axis when at said power tilt position.

6. The illuminated power tilt exterior mirror system of claim 5 wherein said reflective element is downwardly tilted at an angle of at least approximately six degrees from vertical about said horizontal axis when at said power tilt position.

7. The illuminated power tilt exterior mirror system of claim 5 wherein said reflective element is downwardly tilted at an angle in the range of approximately four degrees to approximately six degrees from vertical about said horizontal axis when at said power tilt position.

8. The illuminated power tilt exterior mirror system of claim 1 wherein said exterior mirror assembly is one of a driver side mirror assembly and a passenger side mirror assembly.

9. The illuminated power tilt exterior mirror system of claim 1 wherein said system comprises a foldaway exterior mirror system wherein said housing is selectably retractable to a position close to a side of the vehicle.

10. The illuminated power tilt exterior mirror system of claim 1 further including another mirror assembly having another reflective element wherein said system is part of a multiple mirror interactive system wherein adjustment of the field of view of one said reflective element sets the field of view for the other said reflective element.

11. The illuminated power tilt exterior mirror of claim 1 wherein said reflective element is one of a flat mirror, a convex mirror, and a multi-radius mirror.
