An interior rearview mirror system for a vehicle includes an interior rearview mirror assembly comprising a mirror head. The mirror head includes a first microphone operable to generate a first audio signal and a second microphone operable to generate a second audio signal. An audio sound processor is operable to process the first and second audio signals to enhance human voice to noise clarity. Responsive to processing by the audio sound processor of the first and second audio signals, an audio output is generated that, at least in part, distinguishes a human voice present in the vehicle from noise present in the vehicle. The audio output includes an input to an audio system of the vehicle that transmits wirelessly to a remote receiver. Processing by the audio signal processor of the first and second audio signals to enhance human voice to noise clarity utilizes electronic noise cancelation.

An interior rearview mirror system suitable for use in a vehicle includes an interior rearview mirror assembly having a mirror head and a reflective element. The mirror head includes a first microphone operable to generate a first analog signal and a second microphone operable to generate a second analog signal. The first analog signal is converted to a first digital signal by at least one analog to digital converter and the second analog signal is converted to a second digital signal by the at least one analog to digital converter. A digital sound processor is operable to process the first and second digital signals. Responsive to the processing of the first and second digital signals, the digital sound processor generates a digital output, and the digital output, at least in part, distinguishes a human voice present in the vehicle from noise present in the vehicle.

A vehicular interior rearview mirror assembly includes a circuit board disposed in a mirror casing rearward of a reflective element. A plurality of light emitting diodes is mounted to the circuit board for providing backlighting for a display element disposed rearward of the reflective element. With at least some of the light emitting diodes electrically actuated to emit light, light emitted by actuated light emitting diodes passes through the display element and through a partially transmissive and significantly reflective region of the reflective element for viewing of displayed information by the driver of the vehicle. Individual light emitting diodes are aligned with respective openings through a light reflecting element disposed between the circuit board and the display element. To the driver of the vehicle viewing the reflective element, the presence of the display element is substantially not apparent until at least one of the light emitting diodes is actuated.

Interior rearview mirror assembly for vehicle

An interior rearview mirror system for a vehicle includes a mirror assembly having a variable reflectance element. The variable reflectance element includes a metallic mirror reflector on one side of a substrate, with the metallic mirror reflector being partially transmissive to visible light. The interior rearview mirror assembly includes an information display positioned to the rear of the metallic mirror reflector, wherein the information display emits light that transmits through the metallic mirror reflector for viewing by the driver of the vehicle. Responsive to a light level sensed by at least one light sensor, the luminous intensity of the information display is adjustable by a control to provide a luminous intensity of at least about 750 candelas/sq. meter to a driver of the vehicle viewing the information display through the metallic mirror reflector of the interior rearview mirror assembly when it is normally mounted in the vehicle.

An interior rearview mirror assembly includes a variable reflectance element, an information display and a control for adjusting the luminous intensity of information displayed by the information display. The information display comprises backlighting by a of light emitting diodes. The control is responsive to a light level sensed by at least one light sensor disposed at the mirror assembly, and the control may adjust the luminous intensity of information displayed by the information display, preferably to provide a luminous intensity in a range extending from at least about 750 candelas/sq. meter during a daytime condition to less than about 100 candelas/sq. meter during a nighttime condition. The control adjusts the luminous intensity by use of pulse-width modulation.

An interior rearview mirror assembly suitable for use in a vehicle includes a variable reflectance reflective element, which includes an electrochromic medium, a first information display positioned to the rear of the variable reflectance reflective element, and a second information display. The mirror assembly further includes a single control for adjusting the luminous intensity of the first information display and the second information display and at least one light sensor, with the output of the control being generated responsive to a light level sensed by the at least one light sensor. In addition, the luminous intensity of the first information display and of the second information display increases responsive to the output of the control to compensate for any decrease in transmission of the electrochromic medium.

Information display system for a vehicle

An interior rearview mirror assembly for vehicles incorporates a reflective mirror element and a first polymeric pivot joint allowing pivotal adjustment of the field of view of the reflective element. The assembly includes a polymeric support element, a polymeric rearview mirror mount, and a second polymeric pivot joint. The polymeric support element includes one of a first polymeric ball member and a first polymeric socket. The polymeric rearview mirror mount is adapted for attachment to an interior portion of the vehicle. The support element pivots on the second polymeric pivot joint about the rearview mirror mount. At least one of the pivot joints includes joint members generating increased frictional resistance to movement of a ball member in a socket, such joint members preferably comprising a textured surface on the ball member or socket.

Interior rearview mirror assembly with polymeric components

An interior rearview mirror assembly for vehicles incorporates a rearview mirror mount, a rearview mirror, and a rearview mirror support. The support is pivotally attached to the mirror mount by a first pivot element, and to the rearview mirror by a second pivot element. The mirror mount, support, a rearview mirror housing, and the pivot elements are each formed by molding from polymeric material having a respective color. In various embodiments, the colors may all be substantially the same, such as black, gray, tan, brown, burgundy, green, or another color, or may be different. In one form, the rearview mirror housing includes at least one electrical accessory. Electrical conductors may extend through the pivot elements and mirror support to the rearview mirror housing to provide an electrical connection for the electrical accessory to the vehicle electrical system. The pivot elements preferably include ball pivot members and sockets on various of the mirror mount, support and rearview mirror housing, and may include surfaces for enhanced frictional resistance to pivotal movement.
