An autonomous driving control method for a vehicle includes: converting a driving mode into a restricted area autonomous driving mode in which memory access, communication with a network, and information acquisition are restricted in a restricted area; transmitting a destination in the restricted area and an authentication key to a server by an autonomous driving system; checking validity of the authentication key, and generating a global path to the destination in the restricted area when the authentication key is valid, by the server; encrypting the global path and transmitting it with a decryption key to the autonomous driving system by the server; and restoring the encrypted global path using the decryption key by the autonomous driving system. Autonomous vehicles of the present disclosure may be associated with artificial intelligence modules, drones (unmanned aerial vehicles (UAVs)), robots, augmented reality (AR) devices, virtual reality (VR) devices, devices related to 5G service, etc.
