Energy Management Control of a Plug-In Hybrid Electric Vehicle
First Claim
1. A plug-in hybrid electric vehicle (PHEV), comprising:
- an internal combustion engine;
an electric motor;
an operator-actuated predetermined destination indicator; and
a vehicle system control (VSC) electronically coupled to the engine, motor, and indicator wherein the VSC bases commands to the engine and motor on both;
the predetermined destination indicator having been actuated since a start of the present trip; and
data collected from prior trips to the predetermined destination.

Abstract
A drive-home button is provided in the dashboard of a plug-in hybrid electric vehicle (PHEV). The driver presses this button when heading home or to other predetermined destination at which charging is routinely performed. The actual route, the driving style, and other relevant vehicle/road information during the trip home are stored to build up a statistical database. During a present trip home, a highly probably route is predicted based on prior trips and an energy management profile is calculated. The commands to the internal combustion engine and the electric motor are selected to cause the vehicle'"'"'s battery to be substantially discharged upon arriving at home based on actual data of energy usage by the operator of the vehicle during prior trips. By using actual data, the prediction of energy usage is more accurate allowing more complete discharge of the battery.

7. A method to operate a plug-in hybrid electric vehicle (PHEV) having a battery, comprising:
-
determining whether an operator of the vehicle has indicated an intended destination by actuating a destination indicator coupled to the HEV; determining a most probable route to the indicated destination based on prior trips to the indicated destination; predicting how much energy is expected to be expended en route to the intended destination based on the prior trips; and operating the PHEV based on the predicted energy expected to be expended so that the battery is mostly discharged when the PHEV arrives at the indicated destination. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A plug-in hybrid electric vehicle (PHEV), comprising:
-
an internal combustion engine; an electric motor coupled to the engine via a transmission; an operator-actuated home indicator; a global positioning system (GPS), and a vehicle system control (VSC) electronically coupled to the engine, motor, GPS, and indicator wherein the VSC bases commands to the engine and motor on whether a vehicle operator has actuated the home indicator and GPS data collected during prior trips to home. - View Dependent Claims (18, 19, 20)
