Abstract: A method of controlling an engine oil warning light of a vehicle prevents deterioration of engine oil and reduced durability of an engine that would be caused by non-operation of an engine oil warning light. The method includes: calculating a pressure difference of engine oil; when the initial pressure difference is greater than a predetermined threshold pressure difference, changing a warning light operating pressure determination map; and determining whether or not to turn on an engine oil warning light based on the warning light operating pressure determined by the changed warning light operating pressure determination map.

Abstract: A sealing portion deformation reducing type engine oil pan having a main compartment portion for storage of engine oil, may include a pan bottom portion configured to surround a bottom of the main compartment portion; a pan side portion configured to surround a side of the main compartment portion; and a flange portion configured to be formed at an upper portion of the pan side portion and mounted with a sealing gasket, wherein a reinforcing rib is disposed at a lower portion of the flange portion while being formed at an opening of the fan side portion.

Abstract: A method for preventing misdiagnosis of an oil level sensor may include determining whether a driving status of a vehicle satisfies a first diagnosis condition, a second diagnosis condition or both. When the first diagnosis condition is satisfied, the method may include measuring oil levels, calculating a first average of the measured oil levels, and comparing the calculated first average of the measured oil levels with a predetermined reference oil level. When the second diagnosis condition is satisfied, the method may include measuring oil levels, calculating a second average of the measured oil levels, and comparing the calculated second average of the measured oil levels with the predetermined reference oil level. The method may also include warning an excess of oil when the first, the second or both first and second averages of the measured oil levels are higher than the predetermined reference oil level.

Abstract: A method for managing an oil level for a vehicle includes a key-on process of judging whether the vehicle is in a key-on state or more, a preparation process of judging whether the temperature of engine oil of the vehicle and an engine rpm are within predetermined ranges, a comparison process of comparing the level of the engine oil with a level table additionally provided by continuously measuring the level of the engine oil for a predetermined time when the engine oil is within the predetermined range, and a warning process of giving warning when the level of the engine oil is larger than the value of the level table as a result of the comparison, and a system for managing an oil level for a vehicle.
