Abstract

An interior rearview mirror assembly for a vehicle includes a mirror casing having a human machine interface thereat. The mirror assembly includes a display device disposed behind the transflective mirror reflector of the interior rearview mirror assembly and visible through the transflective mirror reflector to the driver when displaying information. The display device may include a video screen. The user actuatable input may be actuatable by a user to operate at least one element of circuitry disposed in the mirror casing. The human machine interface may be at least partially at a bezel portion of the casing, or may be at least partially at a rear casing portion of the mirror casing.

5. The interior rearview mirror assembly of claim 4, wherein, responsive to said sensing by said sensor, a heating, ventilation and air conditioning system of the equipped vehicle is activated.

6. The interior rearview mirror assembly of claim 5, wherein said activation of said heating, ventilation and air conditioning system is responsive to a detection of a threshold level at said in-cabin surface of the windshield of the equipped vehicle.

7. The interior rearview mirror assembly of claim 6, wherein said threshold level comprises a threshold level of moisture at the in-cabin surface of the windshield of the equipped vehicle.

8. The interior rearview mirror assembly of claim 7, wherein said sensor comprises a capacitive moisture sensor.

9. The interior rearview mirror assembly of claim 2, wherein said display device comprises a back-projected microdisplay.

10. The interior rearview mirror assembly of claim 2, wherein said at least one user actuatable input is illuminated by backlighting.

11. The interior rearview mirror assembly of claim 2, wherein at least one element of said at least one user actuatable input is integrally formed at said bezel portion of said mirror casing during a molding operation that forms said bezel portion of said mirror casing.

13. The interior rearview mirror assembly of claim 2, wherein said circuitry is disposed on a printed circuit board and comprises a switch element that is actuated consequent on a user actuation of said at least one user actuatable input.

14. The interior rearview mirror assembly of claim 2, wherein said circuitry is associated with a moisture sensor for detecting moisture on the in-cabin surface of the vehicle windshield and wherein said moisture sensor comprises a capacitive moisture sensor.

12. The interior rearview mirror assembly of claim wherein said at least one user actuatable input includes at least one actuating portion that is insert molded with said bezel portion of said mirror casing.

15. An interior rearview mirror assembly for a vehicle, said interior rearview mirror assembly comprising:
