PLUG-IN HYBRID ELECTRIC VEHICLE BATTERY STATE OF CHARGE HOLD FUNCTION AND ENERGY MANAGEMENT
First Claim
1. A method of controlling a plugin hybrid electric vehicle including an internal combustion engine, a battery, and an electric machine, the vehicle being operable in a primary electric vehicle driving mode (EV mode) and in a hybrid electric vehicle driving mode (HEV mode), the method comprising:
- receiving input from the driver representing a desired operating mode and a desired energy reservation;
if the desired operating mode is HEV mode, then establishing a state of charge (SOC) offset as the smaller of a maximum SOC offset and an allowable SOC offset, otherwise, establishing the SOC offset based on the desired energy reservation; and
operating the vehicle based on the SOC offset.

Abstract
A plugin hybrid electric vehicle includes an internal combustion engine, a battery, an electric machine, and a controller. The vehicle is operable in a primary electric vehicle driving mode (EV mode) and in a hybrid electric vehicle driving mode (HEV mode). The controller is programmed to receive input from the driver representing a desired operating mode and a desired energy reservation. If the desired operating mode is HEV mode, then a state of charge (SOC) offset is established as the smaller of a maximum SOC offset and an allowable SOC offset, otherwise, the SOC offset is established based on the desired energy reservation. The vehicle is operated based on the SOC offset.

19. A hybrid electric vehicle operable in an electric mode and in a hybrid mode, comprising a controller programmed to:
-
receive input representing an operating mode and an energy reservation; and operate the vehicle based on an SOC offset, wherein, when the operating mode is the hybrid mode, the SOC offset is the smaller of a maximum SOC offset and an allowable SOC offset, otherwise, the SOC offset is based on the energy reservation. - View Dependent Claims (20)
