Device for controlling the operation of at least one functional member of a motor vehicle
First Claim
1. Device for controlling the operating of at least one functional member of a motor vehicle, on the basis of information relating to the brightness in the latter'"'"'s surroundings, comprising at least one brightness sensor (2) associated with means (3) for analysing output signals from this sensor so as to control the operation of the functional member (1), characterized in that the analysis means comprise:
- means (4) for periodically acquiring information about the instantaneous brightness at output from the sensor (2),means (5) for calculating immediate brightness values by calculating the mean, over a first period of time, of the instantaneous brightness values which lie in a first range of determined variation,means (6) for calculating immediate ambient brightness values by calculating the mean, over a second period of time, of the immediate brightness values which lie in a second range of determined variation,means (7) for calculating natural ambient brightness values by calculating the mean of n first immediate ambient brightness values which lie in a third range of determined variation, over a third maximum period of time, andmeans (8) for controlling the operation of the functional member on the basis of these natural ambient brightness values.

Abstract
This device comprising a brightness sensor associated with analysis arrangement for controlling the operation of the member is characterized in that the analysis arrangement comprise arrangement (4) for periodically acquiring information about the instantaneous brightness at output from the sensor, arrangement (5) for calculating immediate brightness values by calculating the mean, over a first period of time, of the instantaneous brightness values, arrangement (6) for calculating immediate ambient brightness values by calculating the mean, over a second period of time, of the immediate brightness values, arrangement (7) for calculating natural ambient brightness values by calculating the mean of n first immediate ambient brightness values, over a third maximum period of time, and arrangement (8) for controlling the operation of the functional member on the basis of these natural ambient brightness values.
