Abstract
A hybrid vehicle includes a location awareness module that determines an energy profile for a portion of a roadway or for a known route. The energy profile includes one or more measurements of regenerative braking operations for predicted braking events. The hybrid vehicle determines an efficient use of an electric motor and generator (EMG) based on the energy profile of the roadway portion or the route. When the energy profile includes a predicted braking event, the hybrid vehicle determines to engage the EMG to discharge the battery system prior to the regenerative braking operation for the predicted braking event.
