a service platform configured to transmit a start point and a destination input by a user through a first standard definition (SD) map to the vehicle,
wherein the vehicle is configured to:
generate a global path by use of the start point, the destination, and a second SD map according to a preset program,
generate a local path matching the global path by use of a high definition (HD) map stored in the vehicle, and
autonomously drive the local path, and
