Engine Power Elevation and Active Battery Charge Energy Management Strategies for Plug-In Hybrid Electric Vehicles
First Claim
1. A method for a vehicle having an engine and a battery configured to respectively deliver engine power and battery power to provide a total output power for powering the vehicle, the method comprising:
- determining an elevated engine power which falls within a total output power range where only engine power without battery power may be delivered to power the vehicle in response to a driver demand power and which is greater than the sum of the magnitudes of the driver demand power and vehicle powering losses; and
controlling the engine to deliver the elevated engine power in response to the driver demand power.

Abstract
A method for a plug-in hybrid electric vehicle (PHEV) having an engine and a battery configured to respectively deliver engine power and battery power to provide a total output power for powering the vehicle includes the following. An elevated engine power which falls within a total output power range where only engine power without battery power may be delivered to power the vehicle in response to a driver demand power and which is greater than the combination of the driver demand power and vehicle powering losses is determined. The engine delivers the elevated engine power in response to the driver demand power. The extra engine power is transferred to the battery for the battery to buffer.
