[0018]
Next, the operation of the embodiment configured as described above will be described. First, at the center, the delivery information indicating the delivery plan of the vehicle is recorded in the dispatch database 22c of the center computer 20. In the recording of the delivery information, the communication with the transport company computer 32, the factory computer 33, the dealer computer 34, etc. is performed, and each vehicle is considered in consideration of the date of shipment from the factory, the date of delivery to the dealer, the transportation schedule of the transport company, and the like. A delivery plan for the vehicle is created, and delivery information representing the created delivery plan is recorded in the center computer 20. In this case, the delivery information includes information indicating the parking position and date and time of the vehicle accumulation area (yard) when the vehicle is shipped from the factory, information and date and time indicating the carrier car on which the vehicle is to be loaded, The location and date and time of the unloading, the final delivery destination (dealer) of the vehicle, and the delivery date and time are included. Further, the delivery plan also includes a vehicle frame number indicating a vehicle for specifying a vehicle to be delivered, and an in-vehicle terminal number indicating an in-vehicle terminal device 10 mounted on the vehicle in association with the delivery information. Have been.
[0019]
When the vehicle is assembled in the state where the delivery plan has been set, the vehicle is moved to a vehicle accumulation site on or near the factory site. In this case, the worker executes the program in FIG. 4 before driving the vehicle and moving to the vehicle accumulation area. The execution of this program may be automatically started when an operator turns on the ignition switch 18 to move the vehicle at the time of shipment from the factory. After the execution of this program is started, the operator inputs the vehicle frame number and the in-vehicle terminal number using the input device 14 at step T10, and transmits them to the center computer 20. Alternatively, the vehicle frame number and the in-vehicle terminal number may be automatically transmitted to the center computer 20 in step T10 after the execution of the program is started.
[0020]
In step S10, the center computer 20 receives the transmitted vehicle frame number and in-vehicle terminal number, and registers and stores it in the vehicle information database 22a of the computer 20. In step S12, based on the delivery information stored in the dispatch database 22c in association with the vehicle frame number and the in-vehicle terminal number, information indicating the parking position of the vehicle accumulation area (yard) at the time of factory shipment is stored. The delivery instruction including the information is transmitted to the in-vehicle terminal device 10. In this case, if the vehicle frame number and the in-vehicle terminal number transmitted to the center computer 20 are not appropriate in light of the vehicle allocation information in the vehicle allocation database 22c, the fact may be transmitted to the in-vehicle terminal device 10.
[0021]
The in-vehicle terminal device 10 receives the delivery instruction including the information indicating the parking position transmitted in step T12, and instructs the parking position using the display 24 and the audio output device 25. The work vehicle moves the vehicle according to the instruction and parks the vehicle at the instructed parking position. During the movement of the vehicle, the in-vehicle terminal device 10 continues to detect the vehicle position based on the signal from the position detector 12 in step T14, and transmits the position information representing the vehicle position to the vehicle frame number and the in-vehicle terminal number. At the same time, the data is transmitted to the center computer 20 every predetermined time. The center computer 20 continues to receive the transmitted position information in step S14. On the other hand, after parking the vehicle at the designated position, the operator removes the ignition key and gets off the vehicle and moves on to the next operation. Therefore, after the operator gets off the vehicle, the center computer 20 stops receiving the position information, and the position information last received by the center computer 20 indicates the parking position of the vehicle.
[0022]
In step S14, the center computer 20 stores the last received parking position information in the vehicle position database 22b, compares the position indicated by the parking position information with the designated parking position, Check the parking position. At this time, if the parking position of the vehicle is not appropriate, information indicating an appropriate moving position is communicated directly to the portable information terminal device 36 held by the worker or via the relay station 31. In this case, since the worker moves the vehicle again in accordance with the notification, the in-vehicle terminal device 10 executes the processing of steps T12 and T14 again to guide the vehicle to the appropriate parking position. On the other hand, if the parking position of the vehicle is appropriate, the processing of the movement instruction in step S14 by the center computer 20 and the reprocessing in steps T12 and T14 by the in-vehicle terminal device 10 are not executed.
[0023]
Instead of using the last received position information in step S14 as the parking position information, the operator uses the input device 14 of the in-vehicle terminal device 10 to notify the center computer 20 of the end of the vehicle movement before getting off. May be transmitted to the center computer 20 together with the vehicle frame number and the in-vehicle terminal number. In this case, the center computer 20 stores the transmitted vehicle position information in the vehicle position database 22b. Then, when the vehicle is not parked at an appropriate position, an instruction to move the vehicle to an appropriate parking position can be transmitted to the in-vehicle terminal device 10. In this case, even when the parking position of the vehicle is appropriate, the movement of the vehicle by the operator can be terminated by transmitting the appropriateness to the in-vehicle terminal device 10.
[0024]
The vehicle moved to the vehicle accumulation area in this way is delivered by a worker of a transportation company to a position where a carrier car for carrying the vehicle is transported. At that time, the operator drives the vehicle and moves to the position of the carrier car. In this case, when the ignition switch 18 is turned on to move the vehicle, the in-vehicle terminal device 10 detects the vehicle position based on the detection signal from the position detector 12 in step T16, and The position information indicating the position is transmitted to the center computer 20 together with the vehicle frame number and the in-vehicle terminal number.
[0025]
On the other hand, in step S16, the center computer 20 receives the transmitted position information and stores it in the vehicle position database 22b. In step S18, the destination of the vehicle is determined by using the received position information, vehicle frame number, and in-vehicle terminal number by referring to the vehicle allocation plan in the vehicle allocation database 22c. The destination of the vehicle is the destination (including the position of the carrier car and the final delivery destination) and the carrier car itself. Then, in step S18, the destination information indicating the position of the carrier car and the carrier car itself is transmitted to the in-vehicle terminal device 10.
[0026]
In step T18, the in-vehicle terminal device 10 receives the carrier car position information, and uses the navigation function of the computer main body 11, the position detector 12, and the map database 13a to specify the destination specified by the carrier car position information ( Route search to the position of the carrier car). Then, the map is displayed on the display 15 and the route to the destination is displayed, and the voice output device 16 provides voice guidance to guide the worker who moves the vehicle to the carrier car about the position of the carrier car. . Thereby, the worker can move the vehicle to the position of the carrier car according to the guidance by the navigation function.
[0027]
After the movement of the vehicle, the operator places the vehicle on the carrier car and operates the input device 14 so that the in-vehicle terminal device 10 displays the carrier information indicating the carrier car on which the vehicle is mounted, the vehicle position, and the like as the vehicle frame number. And the in-vehicle terminal number. In response to the input, the in-vehicle terminal device 10 transmits the input carrier information to the center computer 20 in step T20. The center computer 20 receives the carrier information in step S20, records the carrier information in the vehicle position database 22b, and confirms that the vehicle has been mounted on the carrier car. If the vehicle cannot be put on an appropriate carrier car, the worker is contacted at step S20 through the worker's portable information terminal device 36 or the like, similarly to the processing at step S14. Then move the vehicle.
[0028]
Then, when the vehicle is carried by the carrier car and delivered to the final delivery destination (for example, a dealer), the worker at the final delivery destination or the driver of the carrier car starts the vehicle to drop the vehicle from the carrier car. . When the ignition switch 18 is turned on when the vehicle starts, the in-vehicle terminal device 10 detects the vehicle position based on the detection signal from the position detector 12 in step T22, and outputs position information indicating the vehicle position to the vehicle. It is transmitted to the center computer 20 together with the frame number and the in-vehicle terminal number.
[0029]
On the other hand, in step S22, the center computer 20 receives the transmitted position information and refers to the dispatch plan in the dispatch database 22c to determine whether the vehicle may be dropped off from the carrier car. It is determined whether the goods have been properly transported to the final destination by the carrier car. Then, the determination result is transmitted to the in-vehicle terminal device 10.
[0030]
On the other hand, the in-vehicle terminal device 10 receives this determination result in step T24, and uses the display 15 and the audio output device 16 to instruct the worker who is about to drop the vehicle from the carrier car. If the determination is positive, the operator removes the vehicle from the carrier car. Then, in step T26, position information indicating the vehicle position detected based on the signal from the position detector 12 is transmitted to the center computer 20. The transmission of the position information may be performed according to an instruction of the operator using the input device 14, or the position information may be periodically transmitted to the center computer 20 as in the above-described step T14. The position information immediately before the key is removed may be the position where the vehicle is dropped from the carrier car.
[0031]
If the result of the determination in step S22 by the center computer 20 is negative, the vehicle is not dropped off from the carrier car and the destination is instructed again. Then, this vehicle is transported to the destination again instructed, and the processing of the steps T22, T24, T26 is executed at the destination, and the vehicle is dropped off from the carrier car at the appropriate final destination. . In this case as well, the position information indicating the position where the vehicle is dropped off from the carrier car is transmitted to the center computer 20 by the processing of step T26.
[0032]
The center computer 20 receives the transmitted position information in step S24, records it in the vehicle position database 22b, and finally confirms the delivery destination of the vehicle, and ends the execution of this program. Even in this case, if the delivery destination of the vehicle is incorrect due to the final confirmation, the delivery error is notified to the portable information terminal device 36, the transport company computer 32, the dealer computer 34, etc. owned by the operator. Take the measures.
[0033]
In the above description of the operation, an example has been described in which the vehicles produced in the factory are once collected in an accumulation place, then moved to a carrier car, and delivered to a final destination (for example, a dealer) by the carrier car. However, it is also conceivable that the vehicle is transported from the collection site to the final destination without using the carrier car. In this case, processes such as steps T20, T22, T24, S20, and S22 related to the transportation of the vehicle by the carrier car may be omitted. Further, it is also conceivable that the vehicle is transported from the dump site to the final delivery destination substantially only by the carrier car. In this case, the process in step T18 related to the movement of the vehicle due to traveling may be omitted. Further, there is a case where the vehicle is transported from a factory to a final destination via another facility (for example, a vehicle inspection center). In this case, the processes of steps T16 to T26, S16 to S24, etc. may be repeated for the transit points.
[0034]
As can be understood from the above description of operation, according to the above embodiment, the center computer 20 can recognize each vehicle by the identification information including the vehicle frame number and the in-vehicle terminal number, and can confirm the position of the vehicle by the position information. Therefore, the delivery can be efficiently managed without erroneous delivery of the vehicle.
[0035]
As mentioned above, although one Embodiment of this invention and its modification were described, in implementing this invention, it is not limited to the said Embodiment and its modification, and various things do not deviate from the objective of this invention. Changes are possible.
[0036]
For example, in the above embodiment, the vehicle position is detected in steps T16 and T22, and the position information is transmitted to the center computer 20. However, immediately after the ignition switch 18 is turned on, the position is detected only by the detection signal from the GPS receiver 12a because the vehicle is not in a running state. That is, the accuracy of detecting the vehicle position is slightly low because the correction is not performed according to the turning speed and the traveling speed detected by the gyroscope 12b and the vehicle speed sensor 12c and using the map information in the map database 13a.
[0037]
In order to compensate for the decrease in the position detection accuracy, the vehicle position detection and the transmission of the detected position information by the in-vehicle terminal device 10 may be performed according to an ignition-on routine shown in FIG. The execution of the ignition-on routine is started in step T30, and the computer main unit 11 detects the current vehicle position based on only the detection signal from the GPS receiver 12a in step T32. Next, it is determined whether the current vehicle position is the same as the previous vehicle position. If the current vehicle position is substantially the same as the previous vehicle position, it is determined that the vehicle has not moved, and the execution of the ignition-on routine ends at step T46.
[0038]
If the current vehicle position is not substantially the same as the previous vehicle position, it is determined that the vehicle has moved, and the processing after step T36 is executed. In step T36, position information indicating the vehicle position detected by the processing in step T32 is transmitted to the center computer 20. The transmitted position information is stored in the vehicle position database 22b of the center computer 20 as in the above embodiment. However, this position information is temporary information.
[0039]
After the process in step T36, time measurement by the timer is started in step T38, and the circulation process including steps T40 and T42 is continuously performed from the start of the time measurement until a predetermined time has elapsed. During this circulation processing, in step T40, the vehicle position is detected using all the detection signals from the GPS receiver 12a, the gyroscope 12b, and the vehicle speed sensor 12c of the position detector 12. That is, in addition to the position detection based on the detection signal from the GPS receiver 12a, the correction is made according to the turning speed and the traveling speed detected by the gyroscope 12b and the vehicle speed sensor 12c, and using the map information in the map database 13a. The detected vehicle position is being detected. In the same step T40, the ignition switch 18 is turned on by a calculation using the turning speed and the traveling speed (that is, the traveling route) detected by the gyroscope 12b and the vehicle speed sensor 12c. The vehicle position at the time of the calculation is calculated backward.
[0040]
Then, when the predetermined time elapses, "Yes" is determined in step T42, and in step T44, the position information indicating the back calculated vehicle position is transmitted to the center computer 20 as correct position information. The center computer 20 updates the temporarily stored position information with the position information transmitted at this time. Thus, when the vehicle position is required immediately after the ignition switch 18 is turned on, the position information can be used immediately, although some accuracy is lacked. In other cases, position information indicating the exact position where the vehicle has stopped can be used. Therefore, the predetermined time is set to a time value such that the vehicle position is accurately detected.
[0041]
Further, even after the vehicle has traveled for a distance such that the vehicle position can be accurately detected, the accurate position where the vehicle has stopped can be detected by using the result of the reverse calculation of the vehicle position. Therefore, in this case, instead of the processing in step T42, the travel distance from the stop position of the vehicle is detected based on the time measured in step T38 and the travel speed detected by the vehicle speed sensor 12c. It may be determined whether or not the traveling distance is equal to or longer than a predetermined distance.
[0042]
Next, a description will be given of a modification in which a part of the above embodiment is modified so as to prevent the vehicle from being stolen using the position information transmitted from the in-vehicle terminal device 10 every time the ignition switch 18 is turned on.
[0043]
In this case, the in-vehicle terminal device 10 starts the ignition-on routine of FIG. 6 at step T50 every time the ignition switch 18 is turned on, as in the above-described modification. After this start, in step T52, the vehicle position is detected based on the detection signal from the position detector 12, and in step T54, it is determined whether the current vehicle position is the same as the previous detected vehicle position. If they are the same, "Yes" is determined in step T54, and the execution of this routine ends in step T56. On the other hand, if they are not the same, the position information indicating the detected vehicle position is transmitted to the center computer 20 together with the vehicle frame number and the in-vehicle terminal number in step T58. In this modification, the accuracy of the detected vehicle position, which is a problem in the above-described modification, is not a problem. However, in this case, the detection of the vehicle position when the ignition switch is turned on may be performed as in the above-described modification. .
[0044]
On the other hand, the center computer 20 receives the transmitted position information by the processing of step S30, and stores it in the vehicle position database 22b. Then, in step S32, it is determined whether or not the vehicle specified by the vehicle frame number and the in-vehicle terminal number is currently being delivered based on the vehicle allocation plan stored in the vehicle allocation database 22c. If the vehicle is being delivered, "Yes" is determined in step S32, and the transmitted vehicle position is returned to a normal position in step S34 by referring to the vehicle allocation plan stored in the vehicle allocation database 22c again. It is determined whether there is. If it is normal, "Yes" is determined in step S36, and the execution of this routine ends in step S40.
[0045]
If it is not normal, "No" is determined in step S36, and the process proceeds to step S38. In step S38, information indicating that the delivery of the vehicle is not normal together with the information indicating the vehicle position is transmitted to the worker's portable information terminal device 36, the transport company computer 32, the dealer computer 34, and the like, and in step S40. The execution of this routine ends. The transmission corrects the erroneous vehicle delivery. In this state, if there is a possibility that the vehicle has been stolen instead of an erroneous delivery, for example, a contact cannot be made, the tracking of the vehicle may be started by the processing of step S50 and thereafter, which will be described later.
[0046]
On the other hand, if "No" is determined in step S32, that is, it is determined that the vehicle is not being delivered, in step S42, the storage device 22 such as the vehicle information database 22a indicates that the destination of the vehicle is unknown. It is checked whether data indicating a mode for contacting a person (for example, the current owner of the vehicle) is set. If the communication mode has not been set, “No” is determined in step S42, and the execution of this routine ends in step S48.
[0047]
On the other hand, if the communication mode has been set, "Yes" is determined in step S42, and in step S44, the vehicle position is set in the same manner by the method set by the storage data in the storage device 22. Contact first. The contact information includes various information terminal devices of the vehicle owner, the security company computer 35, and the like. Further, in this case, in step S46, it is checked whether data indicating a mode for tracking a vehicle whose destination is unknown is set in the storage device 22 such as the vehicle information database 22a. If the tracking mode has not been set, “No” is determined in step S46, and the routine ends in step S48.
[0048]
If the mode is set to the tracking mode, the center computer 20 transmits a setting signal for setting the tracking mode to the in-vehicle terminal device 10 in step S50. This setting signal is an instruction signal for setting the in-vehicle terminal device 10 to a mode in which the vehicle position is detected at predetermined time intervals and transmitted to the center computer 20. On the other hand, in-vehicle terminal device 10 receives this setting signal in step T60, and is set to the tracking mode. When the tracking mode is set, the in-vehicle terminal device 10 starts time measurement by a timer in step T62, and starts executing the process of step T66 at predetermined time intervals by the process of step T64. The predetermined time is, for example, about several minutes. In step T66, the vehicle position is detected based on the detection signal from the position detector, and position information indicating the vehicle position is transmitted to the center computer 20.
[0049]
The position information transmitted every predetermined time by the processing of steps T64 and T66 is received by the center computer 20 by the processing of step S52, and is sequentially stored in the vehicle position database 22b. Then, by the process of step S54, the vehicle position is notified from the center computer 20 to the set contact by the method set by the storage data in the storage device 22, as in the process of step S44. This makes it possible to deal with theft of the vehicle.
[0050]
As shown in FIG. 7, the processing of steps T60 to T66 of the above-described routine of the vehicle-mounted terminal device 10 in FIG. 6 is changed to the processing of step T70, and the processing of steps S50 to S54 of the above-mentioned routine of the center computer 20 in FIG. May be changed to the processing of steps S60 to S68.
[0051]
