Method and system for oil life monitoring
First Claim
1. A method of determining a maximum oil change limit of an engine, the method comprising:
- providing a current location indicator of an engine to a controller in response to a current trigger;
wherein the controller is configured to generate and store an oil change index and a maximum oil change limit;
generating a current oil change index using the current location indicator and a current location rating;
generating the maximum oil change limit of the engine using one of;
the current oil change index, andthe current oil change index and an at least one prior oil change index; and
storing the maximum oil change limit using the controller.

Abstract
A method and system of determining a maximum oil change limit for an engine considering the engine operating environment and location is provided. An engine location indicator is generated in response to a trigger, using a locating device in communication with a controller. The locating device may include a global positioning system (GPS) receiver. The engine may be an internal combustion engine on a vehicle configured as one of a hybrid vehicle and an extended range electric vehicle. The trigger may be one of a calendar time, a key-on event, an oil change event, and a signal provided by the controller. The controller may generate the maximum oil change limit of the engine using one or more oil change indices, each defined by the engine location and/or time in location. The maximum oil change limit and/or an oil change limit alert may be provided as an output of the controller.

20. A vehicle including an engine, the vehicle configured to determine a maximum oil change limit of the engine, the vehicle comprising:
-
an engine; a GPS receiver configured to provide a current location indicator of the vehicle in response to a current trigger; a controller in communication with the GPS receiver, the controller configured to; generate a current trigger, generate a current oil change index using the current location indicator, store an at least one prior oil change index, generate a maximum oil change limit for the engine using at least one of the current oil change index and the at least one prior oil change index, store the maximum oil change limit, receive a last oil change event as an input, compare the maximum oil change limit and the last oil change event, and output an oil change limit alert when the maximum oil change limit is met or exceeded; an output device configured to communicate at least one of the maximum oil change limit and an oil change limit alert; and wherein the vehicle is one of a hybrid vehicle and an extended range electric vehicle.
