Claim Text:
1. A charge depleting mode control apparatus of a plug-in hybrid vehicle, comprising: a driving information detector detecting driving information of a vehicle; a mode determining unit determining whether a charge depleting (CD) mode is entered by using a state of charge (SOC) of a battery, provided from the driving information detector; a shift-speed determining unit determining a target shift-speed when the mode determining unit determines that the CD mode is entered; and a shift determining unit determining whether to change the target shift-speed determined by the shift-speed determining unit, wherein the shift-speed determining unit calculates a system efficiency, and wherein the shift determining unit determines whether a shift-speed is shifted by comparing the system efficiency calculated by the shift-speed determining unit with a system loss rate generated at a shift.
