SYSTEM AND METHOD FOR CONTROL OF A HYBRID VEHICLE WITH REGENERATIVE BRAKING USING LOCATION AWARENESS

摘要

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.

1. A hybrid vehicle, comprising:
an internal combustion engine; an electric motor and generator powered by a battery system, wherein the electric motor and generator is operable to perform a regenerative braking operation to recharge the battery system; at least one processing module configured to:
determine a roadway portion and an energy profile for the roadway portion;determine a predicted regenerative braking operation and estimate a charge to be generated by the predicted regenerative braking operation using the energy profile; anddetermine to operate the electric motor and generator to discharge the battery system in an amount at least equal to the estimated charge.
