Method and apparatus for controlling plug-in hybrid electric vehicle

摘要

A method and apparatus for operating a plug-in hybrid electric vehicle are provided. The includes setting an initial distance until charge (DUC) and calculating a current DUC by subtracting a travel distance of the vehicle from the initial DUC after the initial DUC is set. A current distance to empty (DTE) is calculated based on a current state of charge (SOC) of a battery and the current SOC of the battery is compared with a reference SOC. The current DUC is compared with the current DTE when the current SOC is greater than the reference SOC. Thus, whether a high speed condition or a high load condition is satisfied is determined when the current DUC is greater than the current DTE. A driving mode of the vehicle is then set to be a charge sustaining (CS) mode when the high speed condition or the high load condition is satisfied.

1. A method for controlling a plug-in hybrid electric vehicle, comprising:
setting, by a controller, an initial distance until charge (DUC); calculating, by the controller, a current DUC by subtracting a travel distance of the plug-in hybrid electric vehicle from the initial DUC after the initial DUC is set; calculating, by the controller, a current distance to empty (DTE) based on a current state of charge (SOC) of a battery; comparing, by the controller, the current SOC of the battery with a reference SOC; comparing, by the controller, the current DUC with the current DTE when the current SOC is greater than the reference SOC; determining, by the controller, whether a high speed condition or a high load condition is satisfied when the current DUC is greater than the current DTE; and setting, by the controller, a driving mode of the plug-in hybrid electric vehicle to be a charge sustaining (CS) mode when the high speed condition or the high load condition is satisfied.
