ABSTRACT:
A motorized golf cart circuit and apparatus capable of transporting various golf related items including a golf bag carrying golf clubs around a golf course under manual or automatic control is provided. The cart operator is provided with the option of operating the cart either manually by applying pressure to a switch located on the hand grip of the cart apparatus, or automatically in either a timer or a distance travel mode. The timer mode allows the cart operator to send the cart ahead automatically along a straight or curved path set by the operator for a predetermined period of time before the cart circuit automatically turns off. The distance mode of travel allows the cart operator to automatically send the cart ahead, following either a straight or curved path set by the operator for a distance of between 10 and 50 yards. Both the speed and the path of the cart may be varied by the cart operator by turning a balance control knob located on the control panel interface of the golf club cart. A battery safeguard feature ensures that the cart circuit and apparatus is disabled if a battery powering the cart has been incorrectly connected with the cart circuit. Power-on initialization circuitry prevents the cart circuit from operating immediately after the battery or connector plug is connected with the circuit, regardless of the positions of the control panel switches. The cart circuit also includes a "soft-start" feature for preventing the golf cart apparatus from immediately lurching forward upon receipt of a start command from the cart operator.
