Vehicle rearview mirror system with protocol detection
First Claim
1. A vehicular rearview mirror system suitable for use in a vehicle having a vehicle control, said vehicle control generating an output having a particular protocol representing a state of said output, said vehicular rearview mirror system comprising:
- a variable reflective element, said variable reflective element assuming a partial reflectance level in response to a drive signal;
a mirror control, said mirror control responsive to the output of the vehicle control for generating at least one mirror control output, said at least one mirror control output including a value for said drive signal;
said mirror control determining a protocol of said output of said vehicle control including monitoring said output of said vehicle control and attempting to conclude a state of said output of said vehicle control; and
said mirror control determining the protocol of said output at least in part by maintaining a running parameter.

Abstract
A vehicular rearview mirror system suitable for use with a vehicle control, the vehicle control generating an output having a particular protocol representing a state of the output. The vehicle rearview mirror system includes a variable reflective element which assumes a partial reflectance level in response to a drive signal. The rearview mirror system further includes a mirror control that is responsive to the output of the vehicle control for generating at least one mirror control output. The at least one mirror control output includes a value for the drive signal. The mirror control determines the protocol of the output of the vehicle control including monitoring the output of the vehicle control in attempting to conclude a state of the output of the vehicle control.

16. A vehicle rearview mirror system for use with a vehicle having a reverse gear and a reverse-gear indication, said reverse-gear indication having a particular protocol, said mirror system, comprising:
-
an electro-optic reflective element; a controller, said controller establishing a reflectance level of said reflective element including establishing a particular reflectance level of said reflective element in response to the reverse-gear indication indicating that the vehicle is in reverse gear; and said controller determining the protocol of said reverse-gear indication, said determining said protocol including monitoring the reverse-gear indication and attempting to conclude at least one chosen from (i) the vehicle being in reverse gear and (ii) the vehicle not being in reverse gear; and said controller determining the protocol of said reverse-gear indication at least in part by maintaining a running parameter. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A vehicle rearview mirror system for use with a vehicle having a reverse gear and a reverse-gear indication, said reverse-gear indication having a particular protocol, said mirror system, comprising:
-
an electro-optic reflective element; a controller, said controller establishing a reflectance level of said reflective element including establishing a particular reflectance level of said reflective element in response to the reverse-gear indication indicating that the vehicle is in reverse gear; and said controller determining the protocol of said reverse-gear indication, said determining said protocol including monitoring the reverse-gear indication and attempting to conclude at least one chosen from (i) the vehicle being in reverse gear and (ii) the vehicle not being in reverse gear; and wherein said controller determines said protocol at least in part by maintaining a reverse-inhibit-running parameter and determining when said reverse-inhibit-running parameter is at or above a particular high value or is at or below a particular low value. - View Dependent Claims (27, 28, 29, 30, 31)
