Hereinafter, a golf cart control method according to the present invention will be described with reference to FIGS. 9 and 10.

The golf cart control method according to the present invention ensures operation of the golf cart until all holes are completed by efficiently consuming the battery 430.

The golf cart includes a control unit (not shown). The control unit controls the components that make up the golf cart. For example, the control unit can control the operation of the drive motor 420 to move the golf cart, and control the motor 611 of the air conditioner to operate/stop the air conditioner 610.

The control unit calculates a reference value (Ref) (S11). The reference value (Ref) is related to the level of charge of the battery 430. The reference value (Ref) can be calculated by considering the number of holes remaining in the golf game currently in progress, power consumption when driving a golf cart, power consumption of the air conditioner 610, etc.

The control unit checks the charge amount of the battery 430 (S12).

The control unit compares the charge amount of the battery 430 and the reference value (Ref) (S13).

If the charge amount of the battery 430 is higher than the reference value (Ref), the control unit performs normal operation (S14a). The battery charge amount in the S14a state corresponds to the first bar in FIG. 10. At this time, since it is determined that sufficient electrical energy is stored in the battery 430, the control unit can operate the air conditioner 610 without restriction to supply comfortable air to the passengers.

If the charge amount of the battery 430 is lower than the reference value (Ref), the control unit performs a power saving operation (S14b). The battery charge amount in the S14b state corresponds to the third bar in FIG. 10. At this time, because it is determined that insufficient electrical energy is stored in the battery 430, the control unit may limit the operation of the air conditioner 610. For example, the output of the air conditioner 610 may be reduced, the air conditioner 610 may be operated intermittently, or the operation of the air conditioner 610 may be stopped.

The control unit terminates control if the reason for operation termination is met, and if not, steps S12 to S14 are repeated (S15). An example of the reason for driving termination is when the passengers have finished all the holes and the golf game is over.

In the above, preferred embodiments of the present invention have been shown and described, but the present invention is not limited to the specific embodiments described above, and can be used in the technical field to which the invention pertains without departing from the gist of the present invention as claimed in the patent claims. Of course, various modifications can be made by those skilled in the art, and these modifications should not be understood individually from the technical idea or perspective of the present invention.
