Method for changing transparency of reversible darkenable windows of motor car, involves causing uniform transparency change by change in reference variable for windows with respect to rate of change and stationary transparency value
Method for changing transparency of reversible darkenable windows of motor car, involves causing uniform transparency change by change in reference variable for windows with respect to rate of change and stationary transparency value
The method involves actuating two reversible darkenable windows (2, 3) of a vehicle in dependence of a common reference guide (Ts) such that the windows are controlled based on a common reference variable with respect to a window-specific response. A uniform transparency change is caused by a change in a reference variable for the windows with respect to rate of change and stationary transparency value, where the transparency reference value is provided as reference guide. Window-specific manipulated variable for each window is determined. Independent claims are also included for the following: (1) a lightness control unit for a vehicle (2) a darkening device for a vehicle.
