autonomous driving section includes a road section performing autonomous driving of the vehicle; wherein the controller is configured to increase reliability of a result determined based on autonomous driving information obtained in precision diagnosis section having high priority; wherein the controller is configured to set at least one of a straight fixed-speed section, a straight deceleration section, a straight acceleration section, a rapid braking section, a rapid acceleration section, a steering section, a bump section, or a stop state as the precision diagnosis section; wherein the controller is configured to output a warning message for restricting the driving of vehicle and checking the vehicle when the controller determines that the vehicle fails; and wherein the controller is configured to determine that the vehicle is capable of normally driving when the controller does not determine that the vehicle fails. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the controller is configured to collect learning autonomous driving information and perform learning based on the collected learning autonomous driving information to generate the failure sound information. ### Claim 3 (depends on 2) The apparatus of claim 2, wherein the controller is configured to transmit the learning autonomous driving information to a server and receive learned failure
