Claim 9:
10. An autonomous driving method, comprising steps of:
acquiring front image data from a front camera installed in a vehicle and having a field of view facing in front of the vehicle;
receiving, by a communicator, a high definition map at a current location of the vehicle from an external server;
calculating, by a controller, a first distance between the vehicle and a right road boundary line and a second distance between the vehicle and a left road boundary line in response to processing the front image data,
calculating, by the controller, a third distance between the vehicle and the right road boundary line and a fourth distance between the vehicle and the left road boundary line in response to processing the high definition map;
determining, by the controller, a map quality index of the high definition map based on at least one of a difference between the first distance and the third distance or a difference between the second distance and the fourth distance;
determining, by the controller, a map quality index of the high definition map based on at least one of a difference between the first distance and the third distance or a difference between the second distance and the fourth distance by correcting coordinates of the vehicle on the high definition map based on the at least one of a difference between the first distance and the third distance or a difference between the second distance and the fourth distance to correct the determined map quality index;
determining whether an error of the high definition map is present based on the corrected map quality index; and
transferring a control right of the vehicle to a driver in response to a determination that the error of the high definition map is present.
