1. A control apparatus for a rear view reflection mirror of a vehicle having a manipulation device adapted to be manipulated by a vehicle driver to change a moving direction of said vehicle comprising:

  • reflectivity reducing means provided in said reflection mirror for reducing, when electrically driven, reflectivity of light incident thereto;

    darkness detecting means for detecting a dark condition exterior of said vehicle;

    rear light detecting means for detecting an intensity of light incident thereto from the rear of said vehicle and generating a first output signal indicative of the detected rear light intensity;

    manipulation detecting means operatively associated with said manipulation device for detecting a predetermined manipulated condition of said manipulation device and generating a second output signal indicative of a change in the moving direction of said vehicle;

    circuit means, responsive to said darkness detecting means and said rear light detecting means, for generating a third output signal in response to the first output signal of said rear light detecting means when a dark condition is detected by said darkness detecting means; and

    driving means, responsive to said circuit means and said manipulation detecting means, for electrically driving said reflectivity reducing means in response to said third output signal of said circuit means in the absence of said second output signal of said manipulation detecting means so that said reflection mirror is driven into a dazzle-free condition, said driving means preventing said reflection mirror from being electrically driven when said second output signal is generated by said manipulation detecting means.
