Adaptive Initial Estimation and Dynamic Determination and Update of Distance Until Charge of a Plug-In Hybrid Electric Vehicle
First Claim
1. A method for controlling an electric vehicle, the method comprising:
- obtaining historical distance between charges (DBC) values indicative of the distance the vehicle has been driven between each of one or more pairs of consecutive charges of the vehicle;
estimating a distance until charge (DUC) value based on the DBC values; and
controlling battery usage of the vehicle as a function of the DUC value.

Abstract
An electric vehicle such as a PHEV or a BEV and a method of control includes receiving from a user of the vehicle, at an interface of the vehicle, a distance until charge (DUC) value indicative of the distance from a current position that the vehicle is intended to be driven before the vehicle is recharged. Battery usage of the vehicle is controlled as a function of the DUC value. An initial estimate of the DUC value may be made by obtaining historical distance between charges (DBC) values indicative of the distance the vehicle has been driven between each of one or more pairs of consecutive charges of the vehicle. The estimated DUC value is based on the DBC values.

12. The method of 9 further comprising:
-
after the vehicle has been driven a distance, receiving from a user, at the interface of the vehicle, a new DUC value indicative of the distance from a new current position that the vehicle is intended to be driven before the vehicle is recharged; and controlling battery usage of the vehicle as a function of the new DUC value in place of the previous DUC value.

16. A system for controlling an electric vehicle, the system comprising:
-
a controller; and an arbitrator in communication with the controller, the arbitrator configured to receive from a user of the vehicle a distance until charge (DUC) value indicative of the distance from a current position that the vehicle is intended to be driven before the vehicle is recharged; wherein the controller is configured to control battery usage of the vehicle as a function of the DUC value. - View Dependent Claims (17, 18, 19, 20)
