| description | Method of managing the power supply for an electrochromic glass roof panel (1) for a motor vehicle, in which use is made of a computer (2) which is powered by the battery (3) of the vehicle and which is programmed to power the roof panel (1) via electric pulse trains, each electric pulse train exhibiting pulses having a constant amplitude and constant period, the amplitude and/or duration of the pulses in various pulse trains being adjustable as a function of the desired rate of light transmission, these electric pulses being maintained for a maximum duration predetermined so as to avoid discharging the battery (3) and followed by a period during which only the computer (2) is powered, characterized in that the power supply for the computer (2) is disconnected from the battery (3) when the ambient brightness drops below a predetermined threshold.
Procédé de gestion de l'alimentation électrique d'un panneau de toit (1) en verre électrochrome pour véhicule automobile, dans lequel on utilise un calculateur (2) qui est alimenté par la batterie (3) du véhicule et qui est programmé pour alimenter le panneau de toit (1) par des trains d'impulsions électriques, chaque train d'impulsions électriques présentant des impulsions ayant une amplitude et une période constantes, l'amplitude et/ou la durée des impulsions dans différents trains d'impulsions étant réglable en fonction du taux de transmission de lumière désiré, ces impulsions électriques étant maintenues pendant une durée maximale prédéterminée pour éviter la décharge de la batterie (3) et suivies par une période pendant laquelle seul le calculateur (2) est alimenté, caractérisé en ce que l'alimentation du calculateur (2) est déconnectée de la batterie (3) lorsque la luminosité ambiante chute en dessous d'un seuil prédéterminé. |
