1. A vehicle comprising:
- a vehicle detector configured to detect driving environment information about surroundings of the vehicle;
a controller configured to generate a map including at least one of a surrounding terrain, a lane, and a traveling route based on the detected driving environment information; and
a storage configured to store the map,wherein the controller is configured to store the map generated at each driving of the vehicle in the storage as a temporary map, to compare the temporary map with a current map presently applied to the vehicle,wherein the controller is configured to update the temporary man to a new current map when a difference between the temporary map and the current map exists,wherein when the temporary map is updated to the new current map, the controller is configured to assign an identification number to an existing current map, and back up the existing current map in the storage, andwherein the controller is configured to restore the current map to a most recent map among maps backed up in the storage when a predetermined area in which an autonomous driving fails or a number of intervention times of a driver is equal to or greater than a reference value is a map update zone.

8. A control method of controlling a vehicle, the method comprising:
-
detecting driving environment information about surroundings of the vehicle through a vehicle detector, generating a map including at least one of a surrounding terrain, a lane and a traveling route based on the detected driving environment information, and storing the generated map as a temporary map; comparing the temporary map with a current map presently applied to the vehicle; updating the temporary map to a new current map when a number of times a main item of the temporary map is repeatedly measured is equal to or greater than a predetermined number of times and a difference between the temporary map and the current map exists, or when a difference between the temporary map and the current man exists in a predetermined area where an autonomous driving fails or a number of intervention times of a driver is equal to or greater than a reference value; assigning an identification number to an existing current map, and backing up the existing current map; and after the updating of the temporary map to the new current map, restoring the current map to a most recent map among the backed-up maps when the predetermined area in which the autonomous driving fails or the number of intervention times of the driver is equal to or greater than the reference value is a map update zone. - View Dependent Claims (9, 10, 11, 12)

13. An autonomous driving system comprising:
-
a vehicle configured to detect driving environment information about surroundings of the vehicle through a vehicle detector and generate a map including at least one of a surrounding terrain, a lane, and a traveling route based on the detected driving environment information; and an autonomous driving management server configured to store the map transmitted from the vehicle as a temporary map, compare the temporary map transmitted from the vehicle with a current map presently applied to the vehicle at each time of the vehicle travelling, and when a difference between the temporary map and the current map exists, transmit the temporary map to the vehicle for the temporary map to be updated to a new current map, wherein the vehicle is configured to update the temporary map to a new current map when a difference between the temporary map and the current map exists, wherein when the temporary map is updated to the new current map, the vehicle is configured to assign an identification number to an existing current map, and back up the existing current map in a storage, and wherein the vehicle is configured to restore the current map to a most recent man among the maps backed up in the storage when a predetermined area in which an autonomous driving fails or a number of intervention times of a driver is equal to or greater than a reference value is a map update zone. - View Dependent Claims (14)
