Abstract

A method of determining a volume of a fluid in a reservoir arranged in a vehicle includes assessing, via a controller, whether a first sensor operatively connected to the reservoir and configured to detect a predetermined level of the fluid in the reservoir has been triggered. The method also includes detecting, via a second sensor, a vehicle operative state indicative of inclination of a free surface of the fluid in the reservoir. The method additionally includes communicating, via the second sensor, the detected vehicle operative state to the electronic controller and determining a degree of inclination of the free surface of the fluid in response to the detected vehicle operative state. Furthermore, the method includes determining, via the controller, the volume of the fluid in the reservoir when the first sensor has been triggered in response to the determined degree of inclination of the free surface of the fluid.
