Location enhanced distance until charge (DUC) estimation for a plug-in hybrid electric vehicle (PHEV)
First Claim
Patent Images
1. A method comprising:
- upon a vehicle being charged at a location, estimating a distance until charge (DUC) value based only on distances traveled by the vehicle between (i) prior recharges at the same location and (ii) subsequent recharges immediately following the prior recharges, at least two of the subsequent recharges are at different locations;
adapting battery usage per the DUC value to operate the vehicle in a charge depleting mode until an expected recharge.

Abstract
A method and a system augment or improve a distance until charge (DUC) estimation for a vehicle such as a plug-in hybrid electric vehicle (PHEV) by using location information. Such location information may be provided by a global positioning system (GPS) or the like associated with the vehicle. The method and the system generally estimate the DUC value as a function of past driving pattern historical data that is relevant to a current driving situation. To this end, the method and the system ignore past driving pattern historical data that is not relevant to the current driving situation when estimating the DUC value.

10. A vehicle comprising:
-
a battery; a controller configured to, upon the battery being charged at a charge location, estimate a distance until charge (DUC) value based only on distances traveled by the vehicle between (i) prior recharges at a same location as the charge location and (ii) subsequent recharges immediately following the prior recharges, wherein at least two of the subsequent recharges are at different locations from one another; and the controller further configured to adapt usage of the battery per the DUC value so that the vehicle is operated in a charge depleting mode an entire distance the vehicle is intended to be driven until a next charging event. - View Dependent Claims (11, 12)
