[0002]

2. Description of the Related Art Conventionally, a golf cart of this type has a golf bag mounted in front of a clubhouse and is run by a player from the front of the clubhouse toward a tee ground along a traveling path. Then, the golf cart stops based on a stop signal from a magnet or the like provided near the tee ground of each hole. The player dismounts from the golf cart, hits a tee shot on the tee ground, and mounts the golf cart again. Then, the golf cart is run to the position of the next turn at bat and stopped. This operation is repeated, and when the play in the hole is completed, the player gets on the golf cart and the golf cart runs toward the next hole.

At this time, depending on the player, the playing time may become long and the delay may occur. In this case, the distance to the golf cart on which the succeeding player is riding is shortened, the succeeding player is kept waiting, and smooth playing cannot be performed, which may hinder the playing in an extreme case.

In order to eliminate this point, when passing a predetermined check point of a hole, the time elapsed since the front golf cart passed is measured, and the measured time is preset. When the time is longer than the time, the player in the golf cart is informed that the play is delayed, and the play is promptly performed so that the play of the succeeding player is not hindered.

However, in this case, even if the play is delayed, the play delay cannot be recognized until the check point is passed, and when the play delay is passed and the play delay is known, a large delay is already generated and the subsequent delay occurs. It sometimes hindered the player's play.

Next, the control for notifying the player of the delay in play will be described with reference to the flowcharts shown in FIGS. 5 and 6 and FIG.

The golf cart first travels from the storage 62 toward the clubhouse 63 and is stopped in front of the clubhouse A. At the front of the clubhouse A, the golf bag of the player is mounted on the golf cart body 1. The player gets on board. Then, the club house 63 automatically travels along the guide line of the travel path toward the tee ground T of the first hole, and the control based on the flowchart of FIG.

When the golf cart reaches the position B1 of the tee ground on the traveling road, the golf cart is stopped by a stop signal from a magnet or the like. When stopped (step S1), an arrival signal is transmitted from the transmitter 60 as a remote control signal. (Step S2) At the check point X provided near the tee ground T, when the remote control signal from the golf cart is received (step S3), it is determined whether or not this remote control signal is the arrival signal (step S4), and the arrival signal In this case, the counter value of the arrival timer is converted into a remote control signal. (Step S5) Then, this remote control signal is transmitted (step S6), and the process returns to step S3.

On the other hand, in the golf cart stopped at the position of the ground (step S7), the traveling distance counter and the traveling time counter are reset (step S8), and the traveling distance and traveling time are detected based on the tee ground T. Is started.

Then, the reception section 61 waits until the signal from the checkpoint X is received (step S9),
Upon reception, the preset scheduled time is compared with the arrival timer counter value received from the checkpoint (step S10). If the arrival timer counter value is longer than the scheduled time, the interval with the golf cart ahead Is determined to have become longer, the LED 59 is turned on (step S11) to let the player riding in the golf cart recognize that it is late, and the process returns to step S1.

When the arrival timer counter value is shorter than or equal to the scheduled time, it is determined that there is no delay, and LE is set.
D59 is turned off (step S12) and the process returns to step S1.

As described above, the time from when the front golf cart departs from the tee ground position B which is the check point X to when the golf cart arrives at the check point X is measured and compared with the preset time. By doing so, the distance from the golf cart in front can be known.
By turning on the LED 59 when it is determined that this interval has become large, it is possible to let the player riding in the golf cart recognize that there is a delay and to speed up the play.

When each player finishes the tee shot, the player gets on the golf cart, and the golf cart is started from the position B1 of the tee ground toward the position of the next bat. When the golf cart departs, a departure signal is transmitted from the golf cart transmission unit 61 as a remote control signal.

When the checkpoint receives a departure signal as a remote control signal from the golf cart (step S3), it is determined whether or not it is a arrival signal, and if it is not the arrival signal, that is, the departure signal, the arrival timer is reset ( In step S13), the measurement of the time until the subsequent golf cart arrives is started, and the process returns to step S3.

The golf cart departing from the position B1 of the tee ground runs on the running path to the position of the next bat and is stopped.

When stopped (step S1), it is judged whether or not it is the position B of the tee ground (here, B1 of the first hole) (step S7). If it is not the position B of the tee ground, it is stored in the main CPU 14. The planned traveling distance corresponding to the counter value of the traveling time timer is read from the stored data table (step S14), and the planned traveling distance is compared with the traveling distance counter value counted based on the output from the encoder 36. (Step S15).

If the traveling distance counter value is smaller than or equal to the planned traveling distance, it is determined that a delay has occurred with respect to the standard play time in the hole, and the LED 58
Is turned on (step S16) to let the player recognize that a delay has occurred, and the process returns to step S1.

When the traveling distance counter value is larger than the planned traveling distance, it is determined that no delay has occurred with respect to the standard play time in the hole, the LED 58 is turned off (step S17), and step S1 is performed. Return to.

As described above, the traveling distance and traveling time after reaching the tee ground are detected, and the planned traveling distance is set in advance in accordance with the time after reaching the tee ground. It is possible to successively detect whether or not the play is delayed during the play. When the delay starts, the LED 58 is turned on so that the player can immediately recognize that the delay has occurred. As a result, it is possible to prevent a large delay in the play without not knowing that the play is delayed until the next check point X, and the play can be comfortably performed.

At this time, the LED 58 for notifying the player of the delay is separately displayed with the LED 59 indicating that it is delayed for the player who rides the golf cart ahead at the checkpoint X. Then, it is possible to recognize why it is late and take appropriate action.

In the above embodiment, the planned traveling distance is set in advance according to the time after reaching the tee ground, and the planned traveling distance is compared with the actual traveling distance to delay the play. It was decided whether or not there was a delay, but the preset time was set in advance according to the detected running distance, and this scheduled time was compared with the running time after reaching the tee ground to determine whether the play was delayed. May be.

Further, it is possible to efficiently judge whether or not there is a delay during the play of each hole by making a judgment not when the vehicle is relatively running without a delay, but when the player is prone to delay. However, the determination may be made while the golf cart is running.

Further, although the player who gets on the golf cart is made to recognize that there is a delay by turning on the LED 59 and the LED 60, it may be notified by an alarm or the like.

Also, the distance and time from the departure from the tee ground T are measured to determine whether the play is delayed for each hole, but the time and the distance from the departure from the club house A are determined. You may measure and determine if you are delayed throughout the course.
