Apparatus and method for determining error of vehicle

An apparatus for determining failure of a vehicle, the apparatus comprising:

• a sensor configured to obtain autonomous driving information;
• and
• a controller configured to compare the autonomous driving information obtained during autonomous driving with a determination criterion set as failure sound information and to determine whether the failure occurs based on the comparison result,
• wherein the controller is configured to calculate a priority by respectively assigning weights to two or more precision diagnosis sections, when the two or more precision diagnosis sections are included in an autonomous driving section;
• wherein the 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.
