Abstract
Official abstract text for this publication.
A method and system for operating a vehicle that includes a plurality of engine starting devices and an internal combustion engine is described. In one example, the method determines whether or not to inhibit automatic engine stopping so that a lifespan of an engine starting device may be extended. In one example, the inhibiting is based on a ratio of an actual total number of engine starts generated via the engine starting device to an actual total distance traveled by the vehicle since the engine starting device was installed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for operating a vehicle, comprising: inhibiting an automatic engine pull-down via a controller based on a minimum engine running time for enabling automatic engine pull-down as determined via the controller and based on a minimum vehicle travel distance for enabling automatic engine pull-down as determined via the controller, wherein the minimum engine running time for enabling automatic engine pull-down varies as a function of a ratio of an actual total number of engine starts generated via an engine starting device as determined via the controller and an actual total distance traveled by a vehicle since the engine starting device was installed in the vehicle as determined via the controller. 2. The method of claim 1 , wherein the minimum vehicle travel distance for enabling automatic engine pull-down varies as a function of the ratio of the actual total number of engine starts generated via an engine starting device and the actual total distance traveled by the vehicle since the engine starting device was installed in the vehicle. 3. The method of claim 1 , further comprising: automatically starting an engine via the controller when the automatic engine pull-down is not inhibited; and inhibiting the automatic engine pull-down via the controller based on a minimum torque demand for enabling automatic engine pull-down as determined via the controller, wherein the minimum torque demand for enabling automatic engine pull-down varies as the function of the ratio of the actual total number of engine starts generated via an engine starting device and the actual total distance traveled by the vehicle since the engine starting device was installed in the vehicle. 4. The method of claim 1 , further comprises permitting engine pull-down via the controller in response to an operator initiated engine pull-down request; and inhibiting the automatic engine pull-down via the controller based on a minimum power demand for enabling automatic engine pull-down as determined via the controller, wherein the minimum power demand for enabling automatic engine pull-down varies as the function of the ratio of an actual total number of engine starts generated via an engine starting device and the actual total distance traveled by the vehicle since the engine starting device was installed in the vehicle; inhibiting an automatic engine pull-down via the controller based on a minimum battery state of charge (SOC) for enabling automatic engine pull-down as determined via the controller, wherein the minimum battery state of charge for enabling automatic engine pull-down varies as a function of the ratio of the actual total number of engine starts generated via the engine starting device and the actual total distance traveled by the vehicle since the engine starting device was installed in the vehicle; inhibiting the automatic engine pull-down via the controller based on a minimum vehicle speed for enabling automatic engine pull-down as determined via the controller, wherein the minimum vehicle speed for enabling automatic engine pull-down varies as a function of the ratio of the actual total number of engine starts generated via the engine starting device and the actual total distance traveled by the vehicle since the engine starting device was installed in the vehicle; and inhibiting the automatic engine pull-down via the controller based on a minimum transmission assembly input (TrnAin) speed for enabling automatic engine pull-down as determined via the controller, wherein the transmission assembly input speed for enabling automatic engine pull-down varies as a function of the ratio of the actual total number of engine starts generated via the engine starting device and the actual total distance traveled by the vehicle since the engine starting device was installed in the vehicle. 5. The method of claim 1 , wherein the actual total number of engine starts generated via the engine starting device begins with an engine start that immediately follows installation of the engine starting device into the vehicle as determined via the controller.
