Abstract
A charge depleting mode control apparatus of a plug-in hybrid vehicle includes a driving information detector, a mode determining unit, a shift-speed determining unit, a shift determining unit. The driving information detector detects driving information of a vehicle. The mode determining unit determines whether a charge depleting (CD) mode is entered by using a state of charge (SOC) of a battery provided from the driving information detector. The shift-speed determining unit determines a target shift-speed when the mode determining unit determines to enter the CD mode. The shift determining unit determines whether to change the shift-speed determined by the shift-speed determining unit. The shift-speed is determined by using transmission efficiency and motor efficiency when the plug-in hybrid vehicle drives in the CD mode, such that fuel consumption is reduced and performance is improved.
