Abstract
Abstract A control apparatus for a dazzle-free reflection mirror of a vehicle is disclosed. The control apparatus is provided with a rear light sensor and a circuit for driving the reflection mirror into a dazzle-free condition in accordance with an intensity of a rear light detected by said rear light sensor when a light switch is turned on. The control apparatus is further provided with a winker manipulation detecting switch, a reverse position detecting switch and a steering wheel detecting switch for detecting a change in the moving direction of the vehicle. When one of them detects the change in the vehicle moving direction, the dazzle-free operation of the reflection mirror is disabled even if intensive light is incident to the reflection mirror from the rear of the vehicle.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
131 words
A control apparatus for a dazzle-free reflection mirror of a vehicle having a manipulation device manipulated to change a moving direction of said vehicle comprising; darkness detecting means for detecting dark condition at the exterior of said vehicle; rear light detecting means for detecting intensity of a rear light incident from the rear of said vehicle; driving means for driving said reflection mirror into a dazzle-free condition in accordance with intensity of said rear light detected by said rear light detecting means when the dark condition is detected by said darkness detecting means; manipulation detecting means for detecting a predetermined manipulated condition of said manipulation device; disabling means for disabling the driving operation of said driving means when said manipulation detecting means detects the predetermined manipulated condition of said manipulation device.
Claim 2
Dependent Claim
131 words
A control apparatus for a dazzle-free reflection mirror of a vehicle having a manipulation device manipulated to change a moving direction of said vehicle comprising; darkness detecting means for detecting dark condition at the exterior of said vehicle; rear light detecting means for detecting intensity of a rear light incident from the rear of said vehicle; driving means for driving said reflection mirror into a dazzle-free condition in accordance with intensity of said rear light detected by said rear light detecting means when the dark condition is detected by said darkness detecting means; manipulation detecting means for detecting a predetermined manipulated condition of said manipulation device; disabling means for disabling the driving operation of said driving means when said manipulation detecting means detects the predetermined manipulated condition of said manipulation device.
Claim 3
Dependent Claim
38 words
A control apparatus according to Claim 1, wherein said manipulation detecting means includes winker manipulation detecting means for detecting the manipulated condition of a winker switch which is manipulated when said vehicle turns to the left or right.
Claim 4
Dependent Claim
35 words
A control apparatus according to Claim 2, wherein said winker manipulation detecting means comprises a winker manipulation detecting switch which turns on and off in response to turning on and off of said winker switch.
Claim 5
Dependent Claim
30 words
A control apparatus according to Claim 1, wherein said manipulation detecting means includes reverse position detecting means for detecting that a transmission shift lever is located on a reverse position.
Claim 6
Dependent Claim
34 words
A control apparatus according to Claim 4, wherein said reverse position detecting means comprises a back-up light switch for switching the situation thereof when said transmission shift lever is located on a reverse position.
Claim 7
Dependent Claim
31 words
A control apparatus according to Claim 1, wherein said manipulation detecting means includes steering wheel rotation detecting means for detecting that a steering wheel is rotated more than a predetermined angle.
Claim 8
Dependent Claim
101 words
A control apparatus according to Claim 1, wherein said manipulation detecting means comprises winker manipulation detecting means for detecting the manipulation of a winker switch which is manipulated when said vehicle turns to the left or right, reverse position detecting means for detecting that a transmission shift lever is located on a reverse position, steering wheel rotation detecting means for detecting that a steering wheel is rotated more than a predetermined angle, and logic means for detecting that at least one of said winker manipulation detecting means, reverse position detecting means, and steering wheel detecting means detects the predetermined manipulated condition.
Claim 9
Dependent Claim
29 words
A control apparatus according to Claim 1, wherein said driving means drives said reflection mirror continuously into a dazzle-free condition in response to an intensity of said rear light.
Claim 10
Dependent Claim
34 words
