Disclosed herein is a golf cart system enabling a golf cart to autonomously operate and a method of controlling a golf cart using the system. More specifically, when a terminal 400 deviated from its original location where transmission and reception to and from a golf cart are performed or the terminal 400 deviates from a driving restricted area or driving area within a driving area set in the golf cart, the golf cart is automatically stopped. When the terminal 400 enters the driving area again, an accurate location of the terminal 400 is confirmed using a distance value having a minimized error range using a trilateration algorithm, and the golf cart can move rapidly.
