Control device and process for controlling a anti-glare mirror

A preset dimming/fading level (PD/FL) adjusts electrically for a mirror (4), which is charged up and run down to a nominal voltage (NV) assigned to the PD/FL. Applied to the mirror so as to adjust the dimming/fading level, a charging voltage exceeds the NV required for the desired dimming/fading level by fixed amounts. A control device has a full bridge circuit (3,5) and links to a sensor (6). An independent claim is also included for a method for triggering a motor vehicle mirror capable of being dimmed/faded electrically.
