METHOD FOR IMPROVING DISTANCE TO EMPTY (DTE) OF HYBRID ELECTRIC VEHICLE

摘要

Disclosed herein is a method for improving a distance to empty (DTE) of a hybrid electric vehicle. The method includes: a hybrid control unit of the hybrid electric vehicle performing a warning against gasoline fuel exhaustion at a gasoline fuel exhaustion point in time depending on the DTE; deciding whether or not a mode of the hybrid electric vehicle is changed from an HEV mode into an EV mode depending on the warning against the gasoline fuel exhaustion; and driving the hybrid electric vehicle in the changed EV mode, and again changing the mode of the hybrid electric vehicle into the HEV mode when all of the electricity amount is exhausted at the time of driving the hybrid electric vehicle, thereby exhausting a remaining gasoline fuel.

1. A method for improving a distance to empty (DTE) of a hybrid electric vehicle, comprising:
a hybrid control unit of the hybrid electric vehicle performing a warning against gasoline fuel exhaustion at a gasoline fuel exhaustion point in time depending on the DTE, the hybrid control unit deciding whether or not a mode of the hybrid electric vehicle is changed from a hybrid electric vehicle (HEV) mode into an electric vehicle (EV) mode depending on the warning against the gasoline fuel exhaustion; and driving the hybrid electric vehicle in the changed EV mode, and again changing the mode of the hybrid electric vehicle into the HEV mode when all of the electricity amount is exhausted at the time of driving the hybrid electric vehicle, thereby exhausting a remaining gasoline fuel.
