  • the power cord in a motor vehicle consists in the basic structure of a wiring harness, an energy storage, an energy source and the electrical consumers. In principle, several energy stores or energy sources can be used. While in a conventional motor vehicle with a 12V power cord, a generator is used as an energy source, the supply is taken in hybrid or battery vehicles by a DC / DC converter, which in turn is connected to a high-voltage electrical system. The peak power of these energy sources is usually dimensioned so that the average power of all installed systems in the vehicle can be covered. However, the peak power of the installed systems can be many times greater than the average power. While DC / DC converters have great dynamics, the generator in a motor vehicle is limited in its dynamics due to structural reasons.

At the same time, a timer T is started for time monitoring. If the predetermined time interval dT (about 1 to 2 seconds) has expired or exceeded (monitoring in step 30), the terminal voltage is monitored again in method step 40.

Abstract

L'invention concerne un procédé et un dispositif de stabilisation de tension dans un réseau électrique, notamment dans un tableau de bord d'un véhicule automobile, plusieurs consommateurs étant reliés audit réseau électrique. Une unité de surveillance côté consommateur placée au niveau d'au moins un consommateur permet de surveiller la tension appliquée audit consommateur. Lors de la détection d'une chute de tension côté consommateur, le consommateur correspondant est mis en mode de fonctionnement à puissance réduite ou est complètement désactivé.
