Abstract: The present invention relates to a golf cart operating by recognizing a specific behavior of a user as a routine, and a golf cart control method therefor, and, more specifically, comprises: at least one remote controller (100) carried by a user, and a cart (200) capable of performing autonomous driving, stopping, and re-starting by exchanging signals with the remote controller (100), wherein the cart (200) recognizes the user behind the user and performs autonomous driving while keeping a predetermined distance from the user, and, if a specific behavior of the user is recognized, the cart (200) can stop or re-start in response to the specific behavior so that the user can conveniently use the cart even without issuing a command by using the remote controller (100) during stopping or re-starting of the cart.
