Methods and systems for oil leak determination

Abstract

Methods and systems are provided for an oil diagnostic. In one example, a method may include intrusively increasing an oil pump displacement to determine if an internal oil leak is occurring. The method may further include adjusting a parking routine to determine if an external oil leak is determining.

Description

technical field [0001] The present description generally relates to determining oil spills via one or more image capture devices disposed on a vehicle. Background technique [0002] Human determination may become less reliable as future vehicles transition to autonomous driverless vehicles. In addition, users who join car-sharing services may have less vested interest in maintaining their vehicles. As a result, vehicle diagnostics and some maintenance may turn into autonomous as well. [0003] Due to one or more of deteriorating piston rings, deteriorating positive crankcase ventilation valves, deteriorating cylinder head valve guides, and deteriorating turbocharger seals, oil leakage may occur internally which may cause exhaust color and The smell changes. Oil leaks can occur externally due to one or more of deteriorating engine gaskets, rusted / leaking oil pan, loose drain plug, unsecured filler cap, and degraded oil filter. Current oil leak diagnosis may depend on huma...

Problems solved by technology

As an example, spectrometers can be expensive and increase packaging constraints

Additionally, exposure to spectrometer conditions (e.g., temperature, humidity, atmospheric particulate matter, etc.) may degrade the spectrometer, further burdening the vehicle operator and / or requiring diagnostics to determine its fidelity

Additionally, reliance on human operator input can be cumbersome and unreliable for human operators
