Abstract
A vehicle and a method use an Idle Stop and Go (ISG) system. The vehicle includes: a battery; a battery sensor configured to measure a lowest voltage of the battery at a time of startup of the vehicle; a driving unit including an engine of the vehicle; and a controller. The controller is configured to: compare a first lowest voltage predicted using a current lowest voltage of the battery with a reference value to determine whether the lowest voltage of the battery has been changed; in response to determining the lowest voltage of the battery has been changed, calculate a difference between the current lowest voltage of the battery and an immediately previous lowest voltage of the battery; calculate an accumulated current between a current of the battery at the immediately previous time point and a current of the battery at the current time point; calculate a correction voltage for the accumulated current; predict a second lowest voltage using at least one of the difference between the current lowest voltage of the battery and the immediately previous lowest voltage of the battery or the correction voltage; compare the second lowest voltage with a second determination value; and control the driving unit to control entry into a stop of the ISG system according to a result of the comparison.
