FIG. 6 is a diagram showing the circuit of the changeover switch section in a simplified manner, and showing relay control according to a command from the base station (management station) when the key is removed and in an automatic state.

  As shown in the table in the figure, in the normal operation automatic mode, the key state (manual / automatic switch state) of the golf cart is automatic running, and the relay of the changeover switch unit is from the base station (control station). It is turned off by the command.

  The manual evacuation manual mode is a mode in which the relay of the changeover switch section is turned on wirelessly from the base station (management station) when an emergency occurs, and it returns to automatic driving which is no longer an emergency and resumes normal driving again. When playing, the relay of the changeover switch part is turned off by a command from the base station (management station).

  Here, since the switching signal transmitted from the base station is simultaneously received by a plurality of golf carts, the data format of the switching signal transmitted from the base station is transmitted with the ID assigned to each golf cart. To do.

And the golf cart which received the switching signal can know that the golf cart of the object which a base station designates is self by identifying this ID.
Example 1
7 and 8 are flowcharts showing the exchange between the golf cart and the base station when an emergency occurs.

Step S71 is a case where the golf cart is traveling automatically. At this time, the base station also knows that the golf cart is traveling automatically.
When an emergency situation occurs during normal operation (automated driving), for example, when there is a occurrence as shown in activation factor 1 in FIG. 7, it is indicated that the occurrence occurred in step S72, and the user immediately enters the evacuation site. In step S73, a manual switching signal is transmitted to the golf cart so that the user can evacuate.

That is, the base station is switched wirelessly from the golf cart to the golf cart, and the golf cart is manually driven.
Next, when an unexpected situation occurs as shown in the trigger factor 2 in the figure, for example, when the user enters into the base station that he / she wants to suspend play due to sudden illness in step S74, manual switching is performed in step S75. Send a signal to the golf cart.

  Further, when an accident occurs as shown in the trigger factor 3 in FIG. 5, for example, if the golf cart breaks down in step S76, a manual switching signal is set in step S77 so that the accident can be dealt with immediately. Send to.

  Further, when it is necessary to overtake the previous golf cart as shown in the activation factor 4 in the figure, in step S78, the user notifies the base station that he / she wants to overtake the previous golf cart, and manually in step S79. A switching signal is transmitted to the golf cart.

Here, the notification to the base station may be made by preparing a menu button in advance so that the display device can select the content of the communication, and selecting the content of the communication from the menu button.
When the golf cart receives the manual switching signal in step S710 in the same figure, the speed of the golf cart is detected in step S81 shown in FIG. This is because sudden braking is dangerous when switching between manual and automatic during cart travel.

  If the speed becomes 2 km / hour or less in step S82, the operation is considered to be stopped, and the process proceeds to step S83. If the speed is not 2 km / hour or less, the process proceeds to NO and loops until 2 km / hour or less.

  Next, in condition 2, the brake state is detected in step S83. If a brake lock state is detected in step S84, the process proceeds to step S85, and if not locked, the process proceeds to NO.

Here, the brake is a hydraulic brake, and when the hydraulic pressure reaches a predetermined pressure, the brake lock state is notified as a lock state.
Next, in condition 3, switching area detection is performed in step S85. If there is a golf cart other than the dangerous area in step S86, the switch is switched to the manual running state in step S87. When the relay is switched, the manual switching lamp is turned on and the automatic switching lamp is turned off.

Thereafter, the user can drive the golf cart manually to evacuate.
(Example 2)
FIGS. 9 and 10 are flowcharts showing the exchange between the golf cart and the base station when switching from manual to automatic (when returning from an emergency) to normal play.

Step S91 is a case where the golf cart is in a manual running state and the user is driving. At this time, the base station also knows that the golf cart is traveling manually.
In the event of an emergency from manual travel to automatic travel, for example, when play is resumed as shown in trigger 1 in FIG. 9, the employee can stop play from the evacuation area and resume play in step S92. If it is determined, an automatic switching signal is transmitted to the golf cart in step S93.

That is, a switching command is transmitted wirelessly from the base station to the golf cart, and the golf cart is switched to automatic travel.
Next, if there is a request from the user to be switched automatically as in the activation factor 2 in the figure, for example, in step S94, the user has overtaken the golf cart that is traveling in front, so return it. When contact such as wanting enters the base station, an automatic switching signal is transmitted to the golf cart in step S95.

  When the golf cart receives the automatic switching signal in step S96, as shown in condition 1 of FIG. 10, the golf cart is driven on the guide wire to move to a position where the guide wire detection lamp is lit in step S101. In step S102, the induction wire is detected, and if the signal cannot be detected from the induction wire, the automatic running mode cannot be changed, and thus a loop is performed until it can be detected.

Next, in condition 2, the speed of the golf cart is detected. This is because if the manual / automatic switching is performed while the golf cart is running, a sudden brake is applied, which is dangerous.
If the speed becomes 2 km / hour or less in step S103, the operation is considered to be stopped, and the process proceeds to step S104. If the speed is not 2 km / hour or less, the process proceeds to NO and loops until 2 km / hour or less.

Next, in condition 3, the brake state is detected in step S104. If the brake detects a locked state, the process proceeds to step S105, and if not locked, the process proceeds to NO.
In condition 4, the switching area is detected in step S105. If there is a golf cart in the danger area, the loop is not switched until it leaves the danger area.

  If the golf cart is moving outside the danger area in step S106, the switch is switched to the automatic traveling state in step S107, and then the golf cart is automatically traveling.

When the relay is switched, the automatic switching lamp is turned on and the manual switching lamp is turned off.
FIG. 11 is a diagram illustrating an example of a hardware configuration of a golf cart computer that realizes the above-described golf cart control device.

  The computer 110 shown in the figure has a CPU 111, a memory 112, an input unit 113, an output unit 114, a storage unit 115, a recording medium drive unit 116, and a network connection unit 117, which are connected to a bus 118.

(Example 3)
FIG. 12 shows a configuration diagram of this system. Even if the cart control unit 39 and the changeover switch unit 324 are provided as shown in the figure, the same result as in the first and second embodiments described above can be obtained.
Example 4
FIG. 13 shows a configuration in which the lid of the key box 325 is opened and closed by a signal from the changeover switch unit 324. The key box 325 stores the key 145 for controlling the key switch 38 in the cart control unit 39 and controls the key so that it can be taken out as necessary.

  For example, when the golf cart is traveling automatically, the base station knows that the golf cart is traveling automatically. When an emergency situation occurs during normal operation (automatic driving), for example, when a snag occurs, a lock release signal is sent to the golf cart so that the user can immediately evacuate to the evacuation site by indicating that the snail has occurred. Send to. In other words, the key box can be opened and closed wirelessly from the base station to the golf cart, and the golf cart changeover switch unit 324 is controlled by the key 145 so that the vehicle can be manually driven.

  Further, when the user enters the base station to stop playing due to sudden illness or the like, a lock release signal is transmitted to the golf cart. Further, when an accident occurs, for example, when a golf cart breaks down, a lock release signal is transmitted to the golf cart so that the accident can be dealt with immediately. Also, when it is necessary to overtake the previous golf cart, the user notifies the base station that he / she wants to overtake the golf cart, and transmits a lock release signal to the golf cart.

  FIG. 14 shows a configuration diagram of the key box 325. FIG. 14A shows a state in which the lid of the key box 325 is closed (for example, a locked state and a released state). FIG. 14B shows a state where the lid of the key box 325 is opened (for example, a state where the key is taken out). The key box 325 includes a lid 141, a main body 142, and an open switch 143. Here, the open switch is a switch for energizing a solenoid (electromagnetic functional component) described later to open the lid 141. Further, the key 145 is connected to the key box 325 by a chain 144 (wire material) or the like so that the key 145 is not lost. Further, with this configuration, when the key 145 is not in the key box 325, the chain 144 cannot be sandwiched between the lid 141 and the main body and closed. The length of the chain 144 is a length that allows the key to reach the key switch 38.

  Further, the open switch 143 is used when opening the lid 141 that can be opened and closed by receiving a manual switching signal (unlock signal) transmitted from the base station described above. When opening / closing becomes possible, the user is notified that the key 145 can be taken out, for example, by turning on an open switch (LED of a switch that can be displayed).

  FIG. 15 shows a flowchart of this embodiment. In step S151, the lock release signal is transmitted from the base station in order to set the lock state of the key box 325 to the release state by the lock release signal. As shown in FIG. 16A, in the locked state, when the changeover switch unit 324 is configured by a relay, + V (power source) of the key box 325 and one terminal of the switch 161 (open switch 143) are connected. It is not in a state.

In step S152, if the lock release signal is received, the lock is released (Yes). If not received (No), the process waits until the lock release signal is received.
When the switch is released, as shown in FIG. 16B, the relay of the changeover switch unit 324 enters a state in which either + V (power supply) of the key box 325 and one of the switches 161 are connected. Next, when it is recognized in step S153 that the user has been released, the switch 161 is turned on in step S154. If it does not turn on, it waits to receive the unlock signal again. Here, the switch 161 can operate the switch 161 while receiving the unlock signal. However, after receiving the unlock signal, the timer 161 controls the time so that the switch 161 can be operated for a predetermined time. It doesn't matter.

  In step 154, the key box is opened and the key 145 is taken out. As shown in FIG. 16 (c), from the released state of FIG. 16 (b), the switch 161 is turned on to energize the coil of the unlocking solenoid 162 to open the lid 141 of the key box 325 (opening / closing means).
