Abstract

The present invention relates to an apparatus, a method, and a sensor for scanning engine oil of a vehicle. An apparatus for scanning engine oil according to an exemplary embodiment of the present invention includes an oil property measuring part for measuring physical and chemical properties of engine oil; a driving condition measuring part for measuring a engine driving condition; a control portion where predetermined values about conditions of engine oil according to engine driving conditions are stored as set values, for selecting a set value corresponding to a measured engine driving condition and calculating a result value about a quality of engine oil on the basis of comparison with a measured value determined according to an engine driving condition inputted from the driving condition measuring part and the set value; and an output part for outputting the result.

Description

[0001] Related Applications Cited [0002] This application claims the benefit of Korean Patent Application No. 10-2004-0099177 filed on Nov. 30, 2004 at the Korean Intellectual Property Office and Korean Patent Application No. 10-2005-0111791 filed on Nov. 22, 2005 at the Korean Intellectual Property Office and Interest, the entire contents of which are incorporated herein by reference. Background of the invention [0003] (a) Technical field [0004] The invention relates to a device, method and sensor for monitoring the state of vehicle engine oil. According to an embodiment of the present invention, the physical properties, chemical properties, and quantity of the engine oil can be measured with independent sensors or integrated sensors, and then by comparing the measured values ​​of the properties of the engine oil with predetermined values ​​determined according to driving conditions or driving history information , to determine the quality of the engine oil, which is ...
