ABSTRACT:
A method for actuating an electrically dimmable mirror in which a predefined degree of dimming of the mirror is set by charging or discharging the mirror to a predefined setpoint voltage. The method provides for actuating an electrically dimmable mirror in which particularly fast switching over the degree of dimming of the mirror is achieved. In the method, in order to switch over the degree of dimming, a charge voltage is applied to the mirror which exceeds in absolute terms the setpoint voltage which is necessary for the desired degree of dimming, and the setpoint voltage is applied to the mirror after the desired degree of dimming has been attained.
