본 발명은 하이브리드 차량의 주행모드 제어 장치 및 그 방법에 관한 것으로, 하이브리드 차량에 탑재된 배터리의 셀 전압 편차에 기초하여 주행모드(Electric Vehicle (EV) 모드, Hybrid Electric Vehicle (HEV) 모드)의 전환 시점을 조절함으로써, 배터리를 구성하는 특정 셀의 과방전을 방지할 수 있는 하이브리드 차량의 주행모드 제어 장치 및 그 방법을 제공하고자 한다. 이를 위하여, 본 발명은 하이브리드 차량의 주행모드 제어 장치에 있어서, 복수의 셀로 구성된 배터리; 상기 배터리의 각 셀 전압을 측정하는 전압측정부; 및 상기 전압측정부에 의해 측정된 배터리의 각 셀 전압에 기초하여 EV(Electric Vehicle) 모드에서 HEV(Hybrid Electric Vehicle) 모드로의 전환 시점을 조절하는 제어부를 포함한다.

    An apparatus for controlling a driving mode of a hybrid vehicle and a method thereof are provided in which a specific cell, which constitutes a battery, is prevented from being overdischarged by adjusting a switching time point of a driving mode (an electric vehicle (EV) mode or a hybrid electric vehicle (HEV) mode) based on a cell voltage change of the battery mounted in the hybrid electric vehicle. The apparatus for controlling the driving mode of the hybrid vehicle includes a battery including a plurality of cells, a voltage sensor to measure voltages of the cells in the battery, and a controller to control a switching time point from the EV mode to the HEV mode based on the voltages of the cells in the battery, as measured by the voltage sensor.
