Abstract
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.
