Abstract

Abstract Translated from German Spannungsversorgungsvorrichtung für eine, insbes. in einem Fahrzeug angeordnete, Computerelektronik (CE), deren Speicher (MEM) über einen Pufferakkumulator (PA) gespeist sind und deren Spannungsversorgungsleitung (UB) jeweils abhängig von einer Betriebsstellung (BS) eines Zündschalters (Z) von einem Startakkumulator (BA) gespeist wird, der jeweils in einer Anlaßstellung (AS) einen Anlasser (AM) speist, wobei jeweils ein die Betriebsstellung (BS) anzeigendes Betriebssignal (BSS) einem leicht verzögert ansprechenden und stark verzögert abfallenden Zeitschaltglied (TG) zugeführt ist, das von dem Pufferakkumulator (PA) und parallel dazu über eine Entkoppeldiode (D1) von dem Startakkumulator (BA) gespeist ist und das jeweils betätigt die so gebildete Versorgungsspannung (UV) auf die Spannungsversorgungsleitung (UB) schaltet. Voltage supply device for computer electronics (CE), in particular arranged in a vehicle, the memories (MEM) of which are fed via a buffer accumulator (PA) and the voltage supply line (UB) of which is dependent on an operating position (BS) of an ignition switch (Z) The starter accumulator (BA) is fed, which in each case feeds a starter (AM) in a starting position (AS), an operating signal (BSS) indicating the operating position (BS) being fed to a timer switch (TG) which responds slightly delayed and drops off with a considerable delay, which is fed by the buffer accumulator (PA) and in parallel to it via a decoupling diode (D1) from the start accumulator (BA) and which actuates the supply voltage (UV) thus formed and switches to the voltage supply line (UB). Es ist eine Überwachung der Pufferbatterie (PA) vorgesehen. Monitoring of the backup battery (PA) is planned.
