Abstract: The present disclosure redirects unused condensed liquid water from the HVAC system to the washer fluid system such that the washer fluid tank, which may be relatively small and light, does not have to be topped-off frequently. The washer fluid tank is constantly refilled, and the washer fluid supply does not have to be replenished with clean drinking water as often, preserving this important environmental resource. Vehicle sensor data and/or a mobile application usage algorithm control filling of the washer fluid tank, and optionally periodically add anti-freeze from an adjacent reservoir when necessary to maintain an operable washer fluid system even below 0 degrees C.

Abstract: This disclosure relates to methods and devices for estimating amount of washer fluid to be consumed in a reservoir of a vehicle. In an aspect, a method of a processing device (24, 28) of estimating amount of washer fluid (12) to be consumed in a reservoir (11) of a vehicle (10) is provided. The method comprises estimating (S101) at least one of remaining wash cycles that can be performed and remaining driving distance of the vehicle before the amount of washer fluid (12) has reached a predetermined lower amount of washer fluid (12) based on acquired information indicating current amount of washer fluid (12) remaining in the reservoir (11), temperature that the washer fluid is subjected to, and at least one known washer fluid consumption profile, and generating (S102) data representing said estimated at least one of remaining wash cycles and remaining driving distance.
