<p>The present invention relates to a distance-to-empty (DTE) estimation method of an electric vehicle to accurately estimate DTE by using air conditioning load learning values in consideration of the operation condition of various air conditioning devices in driving the electric vehicle. That is, the present invention provides a DTE estimation method of an electric vehicle to accurately estimate DTE according to air conditioning load learning values in various situations. The method accurately estimates air conditioning load learning values according to various situations such as a first air conditioning load using the average value of stabilized conditioning load of shortly-before driving, a second conditioning load learning value using the average of total conditioning load of the shortly-before driving, and a third conditioning load learning value which can deal with weather conditions including long-term soaking, external temperature and solar insolation. The method can be used to calculate an air conditioning reflection rate by using each air conditioning load learning value.</p> |
