摘要： An improved method for predicting the remaining useful life of transmission oil and an apparatus for practicing the same are provided. The method includes: detecting if the transmission has completed a new shift; if yes, determining a total shift count; determining accumulated distance and accumulated time parameters; determining a transmission temperature degradation factor; detecting if the lockup clutch is open and if the transmission is in range; if yes, determining a converter degradation factor; determining a total degradation factor based at least in part upon the transmission temperature degradation factor and converter degradation factor; determining an oil life time limit and oil life distance limit; determining if either the accumulated time parameter is greater than the oil life time limit or the accumulated distance parameter is greater than the oil life distance limit; if yes, activating a service indicator to notify vehicle occupants that transmission oil service is required.

摘要： A vehicle has a transmission, a transmission filter, and a controller having an algorithm or method for predicting the remaining useful life of the filter. The algorithm or method uses a sensor to detect an operating event of the transmission, such as a completed shift event or zero transmission output speed event, and increases a stored value of an accumulated distance and time variable. A shift sensor is operable for comparing a detected speed ratio of the transmission to a stored threshold speed ratio for determining the completed shift event. The remaining useful filter life is predicted using one or more look up tables using the values of the accumulated distance and time variables. The accumulated distance is calculated in part by dividing a prior recorded accumulated distance value by a ratio of an output speed of the transmission to an actual vehicle speed.
