  • Publication number: 20070233339
    Abstract: Golf cart movements at a golf course are controlled by a limited access controller that compares a golf cart's GPS-determined position against a limited access map to restrict performance of inputs by the golf cart's driver to the golf cart's motor under predetermined conditions, such as if a golf cart enters or has a predetermined likelihood of entering a limited access area. The limited access controller inhibits motor responses, such as by preventing motor operation, limiting available motor speeds, or allowing motor operation only in a vector that removes the golf cart from the limited access area, such as operation in reverse. Golf carts of a golf course communicate with a base station that updates the limited access map by defining limited access area perimeters and allowable actions within a limited access area and that directly commands allowable motor operations.
