Abstract

A device may include a washer fluid mixing tank within a compartment of a vehicle. A device may include a concentrate container that is outside the compartment, the concentrate container configured to hold a supply of washer concentrate fluid. A device may include a conduit that fluidly couples the concentrate container to the washer fluid mixing tank such that washer concentrate fluid held in the concentrate container can flow to the washer fluid mixing tank.

First claim

What is claimed is:

1 . A vehicle washer fluid management system, comprising:
a washer fluid mixing tank within a compartment of a vehicle; a concentrate container that is outside the compartment, the concentrate container configured to hold a supply of washer concentrate fluid; and a conduit that fluidly couples the concentrate container to the washer fluid mixing tank such that washer concentrate fluid held in the concentrate container can flow to the washer fluid mixing tank.

2 . The vehicle washer fluid management system of claim 1 , wherein the washer fluid mixing tank is configured to receive a flow of collected fluid from a windshield of the vehicle.

3 . The vehicle washer fluid management system of claim 2 , further comprising a fluid level sensor that measures an amount of collected fluid within the washer fluid mixing tank.

4 . The vehicle washer fluid management system of claim 3 , further comprising a valve between the windshield and the washer fluid mixing tank, the valve configured to block the flow of collected fluid from the windshield in response to the fluid level sensor determining that the amount of collected fluid within the washer fluid mixing tank is above a predetermined threshold.

5 . The vehicle washer fluid management system of claim 4 , wherein the valve is configured to block the flow of collected fluid from the windshield when the concentrate container is empty.

6 . The vehicle washer fluid management system of claim 3 , wherein an amount of washer concentrate fluid that flows to the washer fluid mixing tank is adjusted based on the amount of collected fluid received within the washer fluid mixing tank.

7 . The vehicle washer fluid management system of claim 2 , further comprising a filter configured to filter the flow of collected fluid from the windshield before the collected fluid is received within the washer fluid mixing tank.

8 . The vehicle washer fluid management system of claim 1 , further comprising a flow sensor connected to the conduit and configured to measure an amount of washer concentrate fluid that flows to the washer fluid mixing tank.

9 . The vehicle washer fluid management system of claim 1 , wherein the compartment is an engine compartment.

10 . The vehicle washer fluid management system of claim 1 , wherein the concentrate container is within a passenger compartment of the vehicle.

11 . The vehicle washer fluid management system of claim 10 , wherein the concentrate container is accessible from within a glovebox.

12 . The vehicle washer fluid management system of claim 10 , wherein the concentrate container is disposed adjacent to a charger port.

13 . The vehicle washer fluid management system of claim 1 , wherein the concentrate container is disposed adjacent to a leaf screen of the vehicle.

14 . A vehicle washer fluid management method, comprising:
receiving collected fluid in a washer fluid mixing tank within a compartment of a vehicle; and directing washer concentrate fluid from a concentrate container that is outside of the compartment to the washer fluid mixing tank to allow the collected fluid and the washer concentrate fluid to mix within the washer fluid mixing tank, the concentrate container fluidly coupled to the washer fluid mixing tank through a conduit.

15 . The method of claim 14 , wherein the collected fluid is collected from a windshield of the vehicle.

16 . The method of claim 14 , further comprising measuring an amount of collected fluid received within the washer fluid mixing tank before directing the washer concentrate fluid to the washer fluid mixing tank.

17 . The method of claim 16 , further comprising blocking the collected fluid from being received in the washer fluid mixing tank in response to determining that the amount of collected fluid within the washer fluid mixing tank is above a predetermined threshold.

18 . The method of claim 16 , further comprising blocking the collected fluid from being received in the washer fluid mixing tank in response to determining that the concentrate container is empty.

19 . The method of claim 16 , further comprising adjusting an amount of washer concentrate fluid that is directed into the washer fluid mixing tank based on the amount of collected fluid received within the washer fluid mixing tank.

20 . The method of claim 19 , wherein a ratio of collected fluid and washer concentrate fluid within the washer fluid mixing tank is controlled by a user, weather, exterior temperatures, or any combination thereof.
