PURPOSE: A method for integrating a running distance of an automatic transmission vehicle in case of the failure of a vehicle speed sensor is provided to calculate an integrated running distance even when the vehicle speed sensor is failed while an exhaust gas relating part, a sensor or an actuator has an obstacle, thereby improving the reliability of the vehicle driving which satisfies the E-OBD rules. CONSTITUTION: A method for integrating a running distance of an automatic tranmission vehicle when a vehicle speed sensor is failed includes the steps of detecting state information of a vehicle speed sensor when an error is detected in an exhaust gas relating parts, sensors or an actuator(S102), detecting information on a vehicle speed top dead center, a current transmission and a gear ratio by a set period when an obstacle of the vehicle speed sensor is detected(S103,S104), calculating a current vehicle speed by the operation including the vehicle speed upper dead center information, the gear ratio and a set tire motion radius(S105), and calculating a final running distance by the operation including the calculated vehicle speed and running time and a running distance when the obstacles of the exhaust gas relating parts, the sensors and the actuator are generated(S106).
