Abstract
A washer fluid level indication system of a vehicle determines a present volume of washer fluid present within a washer fluid reservoir. A flowrate module is configured to determine a volume of washer fluid dispensed based on a measured voltage applied to a washer fluid pump and a predetermined volumetric flowrate of dispensing washer fluid calibrated based on a predetermined voltage. The flowrate module is configured to subtract the volume of washer fluid dispensed from the present volume. A level module is configured to determine a present level of washer fluid within the washer fluid reservoir based on the present volume and a predetermined maximum volume of the washer fluid reservoir. A display control module is configured to display the present level of washer fluid within the washer fluid reservoir using a washer level indicator.
