Memory mirror system for vehicles
First Claim
1. A vehicular rearview mirror system for a vehicle having a reverse gear, said mirror system comprising:
- a rearview mirror assembly;
said rearview mirror assembly adapted for attaching said assembly to a vehicle;
said rearview mirror assembly including a reflective element and an actuator for positioning said reflective element about two axes;
said rearview mirror assembly including a control for operating said actuator;
a processor adapted to determine a position for said reflective element, the position of said reflective element determined by one of (i) retrieval of one of several positions stored in a memory at said rearview mirror assembly and (ii) an indication to said processor that the vehicle has been placed in reverse gear; and
wherein said position for said reflective element is communicated from said processor to said rearview mirror assembly, said processor supplying at least two pulse streams, one of said at least two pulse streams being indicative of the position of said reflective element with respect to one of said axes, the other of said at least two pulse streams being indicative of the position of said reflective element with respect to the other of said axes, said at least two pulse streams being multiplexed on a single channel.

Abstract
A vehicle memory mirror system includes a vehicle mirror assembly and a control module. The vehicle mirror assembly includes a reflective element, a motor for positioning the reflective element about an axis, a monitor for monitoring the position of the reflective element with respect to the axis, and a mirror-based control including a position control which is operatively connected with the motor and the monitor in order to position the reflective element at a particular position. The control module is interconnected with the mirror-based control by an analog interface and includes a processor for providing analog signals on the analog interface indicative of a desired position of the reflective element with respect to the axis. The mirror-based control preferably includes a servo-amplifier circuit. The control module can control the speed of movement by formatting a series of sequential signals on the interface, each representing an incremental movement of the reflective element.

30. A vehicular rearview mirror system for a vehicle having a reverse gear, said mirror system comprising:
-
a first rearview mirror assembly and a second rearview mirror assembly;
each of said first and second rearview mirror assemblies adapted for attaching to a vehicle;
each of said first and second rearview mirror assemblies including a reflective element and an actuator for positioning said reflective element about two axes;
each of said first and second rearview mirror assemblies including a control for operating that actuator;
a processor adapted to determine a position for said reflective element of said first and second rearview mirror assemblies, the position of said reflective element of said first and second rearview mirror assemblies determined by at least one of (i) retrieval of one of several positions stored in a memory at said rearview mirror assembly and (ii) an indication to said processor that the vehicle has been placed in reverse gear; and
wherein said position for said reflective element of said first and second rearview mirror assemblies is communicated from said processor to said control for each rearview mirror assembly, said processor supplying at least two pulse streams, one of said at least two pulse streams being indicative of the position of the respective reflective element of said first and second rearview mirror assemblies with respect to one of said axes, the other of said at least two pulse streams being indicative of the position of the respective reflective element of said first and second rearview mirror assemblies with respect to the other of said axes, said at least two pulse streams being multiplexed on a single channel. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62)
