METHOD FOR OPERATING A HYBRID VEHICLE
First Claim
1. A method for operating a hybrid vehicle having a primary power source and an auxiliary power source, comprising the steps of:
- (a) determining if the hybrid vehicle enters a steep grade environment;
(b) if the hybrid vehicle enters the steep grade environment, then making a first set of adjustments to a power management scheme that controls one or more aspects of the primary power source and/or the auxiliary power source; and
(c) operating the hybrid vehicle according to the power management scheme with the first set of adjustments.

Abstract
A method that may be used to operate a hybrid vehicle in a mountainous or other environment where roads have significant grades or inclines. In this kind of setting, standard methods for managing power within the hybrid vehicle may be insufficient when driving the hybrid vehicle up and down substantial inclines and declines; this can be particularly true if the driver attempts to maintain the hybrid vehicle at higher speeds. Thus, this method may use a power management scheme that is specifically adapted to address this kind of situation and can adjust or change target values accordingly, such as those that pertain to a state-of-charge (SOC) for the hybrid vehicle battery.
