Problems solved by technology

[0003] Since the reservoir is placed under the hood of the car, the driver of the car (or car maintenance personnel) cannot see the reservoir without actually opening the hood and performing a close-up inspection of the reservoir - and thus the remaining cleaning fluid level in the reservoir cannot be seen

Embodiment Construction

[0018] figure 1 Shown is a vehicle 10, such as an automobile (autonomous or non-autonomous), equipped with a reservoir 11 containing a washer fluid 12 for cleaning, for example, a windshield 13 and / or cover glass 14 of headlights of the automobile 10, the automobile 10 may perform the techniques of this disclosure.

[0019] One or more passages 15, 16 for conveying fluid are connected between the reservoir 10 and corresponding one or more pumps 17, 18 suitable for use when the driver of the car 10 is in the The inside of the vehicle 10 operates with a washer fluid 12 pumped through spray jets (not shown) onto the windshield 13 and headlight cover glass 14 for proper cleaning control. For autonomous cars, it is also necessary to automatically clean lenses such as LIDAR / radar sensors and cameras.

[0020] Automobile 10 is typically equipped with an electronic control unit (ECU, 24 ), which may be implemented by one or more microprocessors executing appropriate software for con...

Abstract

The disclosure relates to a method and device for estimating the 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 estimatingthe amount of washer fluid (12) to be consumed in the reservoir (11) of the vehicle (10) is provided. The method comprises estimating (S101) at least one of the remaining wash cycles that can be performed and the 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 the acquired information indicating the current amount of washer fluid (12) remaining in the reservoir (11), the temperature that the washer fluid is subjected to, and at least one known washer fluid consumption profile; and generating (S102) the data representing the estimated at least one of remaining wash cycles and remaining driving distance.

Description

technical field [0001] The present disclosure relates to methods and apparatus for estimating the amount of washer fluid to be consumed in a reservoir of a vehicle. Background technique [0002] In a vehicle such as, for example, a car or an autonomous car, a reservoir is generally arranged under the hood of the car to contain the water used for cleaning, for example, the car's windshield, rear window, cover glass of the headlights or parking lot. sensors, lenses for LIDAR sensors or blind spot radar sensors, camera lenses, etc. [0003] Since the reservoir is placed under the hood of the car, the driver of the car (or car maintenance personnel) cannot see the reservoir without actually opening the hood and performing a close-up inspection of the reservoir - and thus the level of cleaning fluid remaining in the reservoir cannot be seen. Typically, the driver of the car or car maintenance personnel will not know the washer fluid level until the reservoir is empty. Content...
