Device for measuring electric current, for detecting lighting characteristics in the surroundings of motor vehicle light sensing system, has capacitor connected to current source, charged by current, switch operated to discharge capacitor

摘要

The device has a capacitor (2) connected to a first connection of the current source (1) and charged by the flowing current, an electrical switch connected to the capacitor, whose operation a causes the capacitor to be discharged, and devices for measuring the charging time and the electrical voltage applied to the capacitor. AN Independent claim is also included for a method of measuring the current from at least one current source.
