First Claim
Patent Images
1. A method for controlling a motive power system of an automotive vehicle wherein the motive power system has a charge sustaining mode and a charge depleting mode, the method comprising:
- determining an expected location of the vehicle;
determining expected environment information based on the expected location of the vehicle; and
requesting the charge sustaining mode if the expected environment information meets a first predetermined criterion, thereby controlling the motive power system.

Abstract
Environment conditions expected to be encountered by a vehicle are used as inputs in determining operating modes of a motive power system of a plug-in hybrid electric vehicle. A vehicle operating in charge depleting mode may transition to operate in charge sustaining mode if the vehicle is expected to encounter circumstances where it is desirable to allow the vehicle to more quickly respond to sudden requests for torque.
