20130131912 | METHOD AND APPARATUS FOR ESTIMATING REPLACEMENT OF VEHICLE ENGINE OIL - A method generates a useful life indication of a lubricating fluid in an engine. Initially, a quantity of use of an engine and a time of use of the engine are measured. A useful life indication of a lubricating fluid in the engine is generated based upon a first relationship between the quantity of use of an engine and the time of use of the engine when an operating characteristic is at or below a predetermined amount, such as the average speed of a vehicle containing the engine. The useful life indication of the lubricating fluid in the engine is generated based upon a second relationship between the quantity of use of an engine and the time of use of the engine when the operating characteristic is above the predetermined amount. | 05-23-2013 |

20090151330 | DETERMINATION OF DIESEL PARTICULATE FILTER LOAD UNDER BOTH TRANSIENT AND STEADY STATE DRIVE CYCLES - Systems and methods for updating the PF soot load of an engine are provided herein. In one embodiment, the method may include performing regeneration in response to both pressure-based measurements as well as estimated soot loading independent of the pressure-based measurements, where during conditions in which the pressure-based measurements may be inaccurate, the soot load is estimated based on operating conditions and previous pressure-based measurements that occurred during previous conditions in which the pressure-based measurements are more accurate. In this way, more continuous monitoring of particulate filter loading is provided, while taking advantage of pressure-based measurements from the most recent accurate reading, for example, and operating conditions that have transpired since such reading, including transient conditions. Thus, more appropriately timed regeneration may be provided. | 06-18-2009 |
