1. A driver's vehicle sound perception method during autonomous traveling, comprising:
determining, by a controller, a driver state using a camera configured to monitor an inside of a vehicle, in the situation where an autonomous vehicle travels at an autonomous traveling grade;
determining, by the controller, positions for a driver and a failed controller within a cabin of the vehicle, in the situation where any one of vehicle system controllers is failed;
confirming, by the controller, an alert utterance position for any one of a vehicle speaker and a personal sound reproduction device of the driver within the cabin by an audio system;
determining, by the controller, an alert output position, which assigns the alert directionality by confirming a driver face direction and a driver position by the audio system, and setting the alert according to the alert directionality;
outputting, by the controller, the sound using any one of the vehicle speaker and the personal sound reproduction device as an alert means;
wherein the perceiving of the driver relative distance includes:
confirming a driver distance for a failed controller with the Bluetooth signal intensity of the personal sound reproduction device, in the situation where any one of the vehicle system controllers is failed;
correcting the driver distance as a device-driver relative distance enhancing the accuracy with an information of a digital key or an information of a radar;
confirming a driver boarding forward or a driver boarding backward as a driver motion according to whether a seat on which the driver sits is rotated; and
generating alert information by setting a sound pressure and a cycle by a combination of the device-driver relative distance and the driver boarding forward or the driver boarding backward.
