Golf cart system capable of autonomous driving based on accurate location information and method of controlling golf cart using the system

A golf cart system capable of autonomous driving based on accurate location information, comprising:

• a cart main body 100 automatically driven by a control module 200;
• a control module 200 comprising a collision prevention sensor 210 configured to prevent a collision by recognizing a target, a GPS sensor 220 configured to provide location information of the cart main body 100, a slope sensor 230 configured to recognize and control a slope, a memory unit 240 configured to store field information of a driving area and driving restricted area of a golf course, a the tracking unit 250 configured to track a terminal 400 in real time, a control unit 260 configured to receive location information of the terminal 400, to calculate a distance from the terminal 400 based on the field information of the golf course stored in the memory unit 240 and to control a movement of the cart main body 100, a communication module 270 for transmission and reception with the terminal 400, and a distance measurement unit 290 configured to measure a distance between the control module 200 and the terminal 400;
• a server 300 transmitting the field information of the golf course to the memory unit 240;
• and
• the terminal 400 operating in conjunction with the control module 200 selectively or in real time,
• wherein three or more fixed nodes 120 are configured at locations spaced apart from one another on one side of the cart main body 100 and are connected to the control module 200, wherein the fixing node 120 is a reference of coordinates, and
• the distance measurement unit 290 sequentially calculates the distance between each of the fixed nodes 120 and the terminal 400, calculates an x,y coordinate value of the terminal 400 by substituting a trilateration algorithm into the x,y coordinate value, determines the x,y coordinate value to be the location values of the terminal 400, calculates a distance and angle □ between the location value of the terminal 400 and the fixed node 120 of the reference, and transmits a result of the calculation to the control module 200 so that the cart main body 100 autonomously drives.
