VERFAHREN ZUR RÜCKGEWINNUNG VON REGENWASSER AUF DER OBERFLÄCHE EINES FAHRZEUGS, RÜCKGEWINNUNGSKREISLAUF UND MIT EINEM SOLCHEN KREISLAUF AUSGESTATTETES FAHRZEUG

摘要

The invention proposes a method for recovering a liquid collected on an interior or exterior surface (1, 19) of a motor vehicle bodywork (17) or glazing (2) element, characterized in that it consists in analysing a quantity of the collected liquid stream using a device (30) for measuring or estimating a parameter indicative of a state of pollution of the collected liquid, such as its turbidity, in comparing a measured value of the turbidity against a threshold value and, when the measured value is below the threshold value, in directing the collected liquid stream towards a recovery unit (9) or, when the measured value is above the threshold value, in discharging the collected liquid stream, for example in the form of waste.
