[Prior art]
As a conventional method for notifying the approach of a bus to a bus stop, for example, there is one disclosed in Japanese Patent Laid-Open No. 7-33496. That is, an approach signal having a preset electric field level is transmitted from the bus radio at a predetermined interval, and an arrival signal having an electric field level preset at a predetermined interval is transmitted from the radio transmitter on the display board at the bus stop. When the bus approaches the stop to some extent (when the bus radio cannot receive the arrival signal transmitted from the radio transmitter on the stop display board and the bus approach signal exceeds the received electric field level), the display The board controller receives the approach signal transmitted from the bus radio with the radio transmitter of the display board and compares it with the approach signal stored in the memory circuit of the radio transmitter of the display board. The information of the approach signal transmitted from the radio device of the approaching bus is stored in the storage circuit, and the approach notice indicator indicating that the bus is approaching the stop is turned on. When the bus further approaches the stop (the position where the bus radio can receive the arrival signal transmitted from the radio transmitter on the stop display board), the bus radio displays the approach stop board An arrival signal (stop number of the stop) transmitted from the wireless transmitter is added and an approach signal is transmitted, it is determined that the bus has arrived at the stop, and the approach notice indicator is turned off.

[0027]
The mutual operations on the shared bus 1 side, the management center 3 side, and the bus stop 5 side when displaying the scheduled arrival time of the shared bus 1 at the bus stop 5 will be described using the flowchart shown in FIG.
First, when the shared bus 1 and the travel route are determined, in step 202 from the management center 3 side, latitude / longitude information indicating the positions of all bus stops that stop on the travel route, each approach area (approach range) of all bus stops. Is set, and the position information (entrance latitude / longitude information, exit latitude / longitude information) is transmitted to the bus 1. In step 204, the position information of all bus stops and the approach area (access range) information of all bus stops are stored in the PC (communication equipment) 15 of the communication unit (vehicle equipment) 11 incorporating the GPS receiver of the shared bus 1. Are stored in the RAM built in the control CPU 12, and latitude / longitude indicating the positions of all bus stops that stop on the travel route and each approach area (approach range) of all bus stops are set.
[0028]
In this state, the shared bus 1 starts running. When this shared bus 1 starts traveling, in step 206, the control CPU 12 of the communication unit (vehicle equipment) 11 incorporating the GPS receiver of the shared bus 1 receives GPS position signals transmitted from GPS satellites at regular intervals. The latitude / longitude data of the shared bus 1 received by the machine 13 and calculated based on the received GPS position signal is stored in the RAM built in the control CPU 12 of the communication unit (vehicle-mounted device) 11 of the shared bus 1. It is determined whether or not it coincides with the entrance latitude / longitude data of the approach area (approach range) of the bus stop that stops on the travel route. That is, it is determined whether the shared bus 1 has entered the approach area of the bus stop. This determination is performed until the shared bus 1 enters the approach area of the bus stop.
[0029]
In this step 206, the latitude / longitude data indicating the position of the shared bus 1 coincides with the entry latitude / longitude data of the approach area (approach range) of the bus stop, that is, the shared bus 1 is within the approach area of the bus stop. In step 208, the latitude / longitude information of the shared bus 1 at that time is detected by the control CPU 12 of the communication unit (vehicle device) 11 and the PC (communication device) of the communication unit (vehicle device) 11 is detected. The location information received by the relay company 2 is transmitted to the management center 3 via the relay company 2.

The latitude / longitude information of the shared bus 1 is received, and the latitude / longitude information of the shared bus 1 is registered in the data memory area 39. Then, the management center 3 uses the road information stored in the road information database 38 to calculate the scheduled time when the bus 1 arrives at the corresponding bus stop 5 and arrives by the calculation. The scheduled time is transmitted to the display device 51 of the corresponding bus stop 5. On the bus stop 5 side that has received the estimated arrival time from the management center 3 side, the CPU 52 receives the estimated arrival time via the receiver 53 of the display device 51 in step 212, and the CPU 52 receives the display 55. The scheduled arrival time of the shared bus 1 is displayed.
The estimated arrival time displayed on the display 55 by the CPU 52 of the display device 51 is not only the estimated arrival time calculated based on the road information stored in the road information database 38 on the management center 3 side, but also the management center 3. The estimated arrival time may be calculated in advance based on the stored road information or the like and stored in the ROM built in the CPU 52. In the latter case, the CPU 52 of the display device 51 of the bus stop 5 receives the estimated arrival time transmitted from the management center 3 and does not need the function of displaying the content on the display 55, but simply stores it in the built-in ROM. It only needs to display a certain estimated time of arrival, and does not require a complicated configuration.
[0031]
As described above, in step 214, the control CPU 12 of the communication unit (vehicle equipment) 11 incorporating the GPS receiver of the shared bus 1 that has entered the approaching area of the bus stop determines the position signal transmitted from the GPS satellite at a constant interval. The latitude / longitude data of the shared bus 1 received by the GPS receiver 13 and calculated based on the received GPS position signal is stored in the built-in RAM of the control CPU 12 of the communication unit (in-vehicle device) 11 of the shared bus 1. It is determined whether or not it coincides with the exit latitude / longitude data of the approach area (approach range) of the bus stop that stops on the traveling route. That is, it is determined whether or not the shared bus 1 has exited from the area close to the bus stop. This determination is performed until the shared bus 1 exits the approaching area of the bus stop.
[0032]
In step 214, the latitude / longitude data indicating the position of the shared bus 1 coincides with the exit latitude / longitude data of the approach area (approach range) of the bus stop, that is, the shared bus 1 exits the approach area of the bus stop. When it is determined, in step 216, the latitude / longitude information of the shared bus 1 at that time is detected by the control CPU 12 of the communication unit (in-vehicle device) 11 and the PC (communication device) 15 in the communication unit (in-vehicle device) 11 is used. The location information transmitted to the relay company 2 and received by the relay company 2 is transmitted to the management center 3 via the relay company 2.
[0033]
On the management center 3 side that has received the transmission of the latitude / longitude information of the shared bus 1 from the communication unit (in-vehicle device) 11 of the shared bus 1, in step 218, the communication unit (in-vehicle device) 11 of the shared bus 1 transmits the information. The latitude / longitude information of the shared bus 1 is received, and the latitude / longitude information of the shared bus 1 is registered in the data memory area 39. On the management center 3 side, it is determined that the shared bus 1 has gone out of the approach area (approach range) and the bus stop indicates that the shared bus 1 has gone out of the close area (access range) of the bus stop 5. 5 to the display device 51. On the side of the bus stop 5 that has received the signal transmitted from the approach area (approach range) of the bus stop 5 from the management center 3 side, in step 220, the CPU 52 of the receiver 53 of the display device 51 of the bus stop 5 The CPU 52 displays on the display 55 that the bus 1 has gone out of the approach area (access range) of the bus stop 5. The indication that this shared bus 1 has gone out of the approach area (approach range) of the bus stop 5 is positively displayed that the shared bus 1 has gone out of the approach area (approach range) of the bus stop 5 Alternatively, the indication that the bus 1 has arrived at the bus stop 5 may be simply turned off.

When pick-up bus 1 enters the pick-up contact area at the bus pick-up stop base, the pick-up bus user 6 is automatically notified (message) of the estimated arrival time to the pick-up stop base of pick-up bus 1, and pick-up bus FIG. 12 shows the mutual operation of the pick-up bus 1 side, the management center 3 side, and the pick-up bus user 6 side when the user 6 makes an inquiry about the estimated arrival time of the pick-up bus 1 to the bus pick-up stop base. It demonstrates using the flowchart of these.
First, when the pick-up bus 1 and the pick-up route are determined, in step 302 from the management center 3 side, latitude / longitude information indicating the positions of all bus pick-up stops that stop on the pick-up route and lift the occupant, all bus pick-up An area for pick-up communication at the stop base is set, and its position information (latitude / longitude information) is transmitted to the pick-up bus 1. The location information of all bus pick-up stops and the area information of each pick-up contact at all bus pick-up stops are obtained in step 304 by the PC (communication equipment) of the communication unit (vehicle equipment) 11 incorporating the GPS receiver of the pick-up bus 1. ) Received at 15 and stored in the RAM built in the control CPU 12, latitude and longitude indicating the location of all bus pick-up stops that stop on the pick-up route and lift the occupant, and contact information for all pick-up points at all bus pick-up stops Set the area.
[0045]
In this state, the shuttle bus 1 starts running. When this pick-up bus 1 starts traveling, in step 306, the control CPU 12 of the communication unit (vehicle equipment) 11 incorporating the GPS receiver of the pick-up bus 1 receives GPS position signals transmitted from GPS satellites at regular intervals. The latitude / longitude data of the pick-up bus 1 received by the machine 13 and calculated based on the received GPS position signal is stored in the RAM built in the control CPU 12 of the communication unit (vehicle equipment) 11 of the pick-up bus 1. It is determined whether or not it matches the latitude / longitude data of the pick-up contact area of all bus pick-up / stop bases that stop on the pick-up route and lift the occupant. That is, it is determined whether or not the pick-up bus 1 has entered the pick-up contact area at the bus pick-up stop base. This determination is performed until the pick-up bus 1 enters the pick-up contact area of the bus pick-up stop base.
[0046]
In this step 306, the latitude / longitude data indicating the position of the pick-up bus 1 coincides with the latitude / longitude data of the pick-up contact area of the bus pick-up stop base, that is, the pick-up bus 1 is the pick-up notice of the bus pick-up stop base. If it is determined that the vehicle has entered the area, in step 308, the latitude / longitude information of the pick-up bus 1 at that time is detected by the control CPU 12 of the communication unit (vehicle device) 11, and the PC (communication) of the communication unit (vehicle device) 11 is detected. The location information received by the relay company 2 is transmitted to the management center 3 via the relay company 2.
[0047]
On the management center 3 side that has received the latitude / longitude information of the pick-up bus 1 from the communication unit (on-vehicle equipment) 11 of the pick-up bus 1, the communication unit (on-vehicle equipment) 11 of the pick-up bus 1 sends it at step 310. The latitude / longitude information of the pick-up bus 1 is received, and the latitude / longitude information of the pick-up bus 1 is registered in the data memory area 39. On the management center 3 side, the estimated time of arrival of the pick-up bus 1 at the relevant bus pick-up stop base is calculated using the road information stored in the road information database 38, and the calculated arrival time is obtained. The scheduled time is transmitted to the shuttle bus user 6 from the CPU 52 via the relay company 2. When the estimated arrival time is transmitted from the management center 3 side, the pick-up bus user 6 receives the estimated arrival time from the management center 3 side by the communication terminal in step 312.
[0048]
Next, an inquiry about the scheduled arrival time of the shuttle bus 1 by the shuttle bus user 6 will be described.
In step 314, the shuttle bus user 6 inquires the management center 3 of the scheduled arrival time of the shuttle bus 1 that he / she uses by specifying the location of the shuttle. When there is an inquiry from this pick-up bus user 6, the management center 3 polls the picked-up pick-up bus 1 for the latitude / longitude of the travel position of the pick-up pick-up bus 1 at step 316. . When there is a polling from the management center 3, the pick-up bus 1 detects the latitude / longitude information of the pick-up bus 1 in step 318 and transmits the detected latitude / longitude information of the pick-up bus 1 to the management center 3. .
[0049]
On the side of the management center 3 that has received the latitude / longitude information of the pick-up bus 1 from the communication unit (vehicle equipment) 11 of the pick-up bus 1, in step 320, the information is sent from the communication unit (car-mounted equipment) 11 of the pick-up bus 1. The latitude / longitude information of the pick-up bus 1 is received, and the latitude / longitude information of the pick-up bus 1 is registered in the data memory area 39. On the management center 3 side, the estimated time of arrival of the pick-up bus 1 at the relevant bus pick-up stop base is calculated using the road information stored in the road information database 38, and the calculated arrival time is obtained. The scheduled time is transmitted to the shuttle bus user 6 from the CPU 52 via the relay company 2. When the estimated arrival time is transmitted from the management center 3 side, the pick-up bus user 6 receives the estimated arrival time from the management center 3 side by the communication terminal in step 322 and receives the estimated arrival time received on the display of the communication terminal. Display the time. The estimated arrival time can be known from the ringing tone when the mobile terminal receives an e-mail if the time from the e-mail ringing tone until the pick-up bus 1 arrives is set in advance.
[0050]
When all bus pick-up stops on the pick-up route are sequentially stopped in this way, the pick-up bus 1 determines in step 324 whether or not it has reached the final pick-up position on the pick-up route. If it is determined in step 324 that the pick-up position of the pick-up bus 1 is not at the final pick-up position on the pick-up route, the process returns to step 306 and the same operation is repeated for each bus pick-up stop base. If it is determined in step 324 that the pick-up position of the pick-up bus 1 has reached the final pick-up position on the pick-up route, in step 326, the latitude / longitude information of the pick-up bus 1 detected at that time is transmitted to the management center 3 side. At the same time, the completion of the transfer by the shuttle bus 1 is transmitted to the management center 3 side. When a transfer completion signal from the shuttle bus 1 by the shuttle bus 1 is transmitted, the management center 3 in step 328 sends the latitude / longitude of the shuttle bus 1 transmitted from the communication unit (vehicle equipment) 11 of the shuttle bus 1. The longitude information is received, and the latitude / longitude information of the pick-up bus 1 is registered in the data memory area 39. Then, the management center 3 confirms the completion of the pick-up by the pick-up bus 1, and ends this flow.
