Abstract

The present invention relates to an engine oil level monitoring system and method, in particular, an oil monitoring system includes a level module, a limit module and a remedial measure module. The level module is configured to determine N oil levels of an engine of the vehicle, where N is an integer greater than one. The limit module is configured to determine an oil level trend based on the N oil levels and to estimate when the oil level in the engine will exceed a predetermined range based on the oil level trend. The remedial action module is configured to perform remedial action based on an estimate of when the oil level will exceed a predetermined range.

Description

[0001] Cross References to Related Applications [0002] This application is related to US Patent Application No. 13 / 082,798 filed April 8,2011. The disclosure of the above application is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates to engine diagnostic and prognostic systems, and more particularly, to engine oil level monitoring systems. Background technique [0004] The background description provided herein is for the purpose of generally presenting the context of the disclosure. The work of the presently listed inventors, to the extent they are described in the Background and to the extent that they may not constitute prior art at the time of filing, is neither expressly nor impliedly is prior art for this disclosure. [0005] Oil circulates through the engine to lubricate the moving parts. The engine's oil pump pumps oil from the sump to various locations within the engine. Gravity causes oil to drain fro...
