Description

  The present invention relates to an improvement in navigation technology for guiding roads of a moving body, and in particular, provides guidance related to ETC.

  In recent years, with the development of electronic technology, various technologies for processing information related to driving of a car with a computer have appeared. For example, a navigation system is known as a device that is mounted on a moving body such as an automobile and performs route guidance.

  This navigation system searches for the optimum route to a given destination based on road data recorded on a CD-ROM or the like, and determines the current position of the own vehicle (referred to as the own vehicle position) by GPS or the like. Calculate sequentially. Then, while displaying the route and road around the vehicle position in real time on a liquid crystal screen or the like, the left and right turning points are notified by display or synthesized speech. Such information processing is called navigation, and if such a navigation system is used, it is easy to run smoothly on the right road even in the place or area where it runs for the first time.

  In addition, as a technology for collecting tolls on toll roads such as expressways without stopping the vehicle, a non-stop automatic toll collection system (Electronic Toll Collection system, referred to as “ETC” in this application) is known. Yes. This ETC wirelessly communicates information necessary to replace conventional passports between electronic devices installed at entrances and exits of toll roads and electronic devices installed in each vehicle. The toll is charged to the vehicle.

  Specifically, for example, on the toll road side, roadside devices equipped with wireless communication antennas are installed at the entrance gate, exit gate, check barrier on the way, etc., and connected to the information processing computer and its network And build a toll collection system. Each vehicle is equipped with an in-vehicle device for transmitting / receiving information such as an identification code to / from road devices.

  When the on-road device at the toll road entrance detects the approach of the vehicle by the vehicle detection sensor, the vehicle type is identified by the vehicle type identification device, and necessary information is exchanged by wireless communication with the in-vehicle device. At this time, for example, information such as the entrance, time of entry, and vehicle type is sent from the road device to the on-vehicle device and stored, and the fee is charged by passing the information from the on-vehicle device to the on-road device. The fee charged in this way is settled by a predetermined credit card, account withdrawal, advance payment, later bill payment or the like.

  Since such ETC collects tolls without stopping the vehicle, it is expected to have an effect of alleviating traffic congestion by increasing the processing capacity per unit time of the toll booth by, for example, four times, and is being tested for actual operation. It is in operation.

  In the conventional toll booth, there are multiple lanes corresponding to individual staff and automatic ticket machines, but for the time being ETC operation, some of the lanes are designated as ETC dedicated entrances and exits (ETC dedicated lanes and lanes). There are also measures to deal with the case where a vehicle not equipped with an in-vehicle device accidentally enters the ETC lane.

  By the way, the conventional navigation system as described above has a problem that guidance on ETC cannot be performed because ETC is not premised. For this reason, the driver has to make his own determination as to whether the toll gate to be passed is equipped with ETC facilities and where the ETC dedicated lane is, and there is a problem that it is complicated.

  The present invention has been proposed in order to solve such problems, and an object of the present invention is to provide a navigation technology for performing guidance related to ETC, that is, a navigation system and method, and a recording medium on which navigation software is recorded. It is.

  In addition, in a database such as a CD-ROM for recording road information, etc., ETC installation information such as which toll booth is installed and whether the ETC lane is on the right or left is recorded in advance. Even when guidance regarding ETC is performed based on information, there is a case where guidance cannot be made to pass through the ETC dedicated lane even though the ETC dedicated lane is installed at the toll gate.

  Such a situation occurs when the ETC installation information is not recorded in the database in the first place, but the update of the database cannot catch up because the ETC is installed at new toll stations one after another with the spread. In this case, according to the ETC installation information, it was found that an ETC dedicated lane was created when actually passing through a toll booth that should have no ETC facilities, and it was necessary to solve this problem.

  In addition, there are two types of toll collection system on toll roads. The one that collects charges at the exit based on the pass ticket issued at the entrance is called the entrance ticketing exit collection system, and a fixed fee is collected at the entrance. What is completed is called a simple receipt method. In the former case, it is necessary to pass through the ETC exclusive lane at the exit, but in the latter case, it is not necessary, so guidance on this point is necessary.

  In addition, when the navigation system obtains toll information related to road use such as the billing amount by ETC from the outside, not only such fee information is recorded but also the vehicle position and current time calculated using, for example, GPS. If it is recorded or displayed in association with such information, it becomes easy to use information such as operation management.

  That is, another object of the present invention is to provide a navigation system technique for guiding an ETC-dedicated lane even if there is no ETC installation information related to ETC in a database such as a CD-ROM. Another object of the present invention is to provide a navigation technique for giving guidance instructions by voice or display as to whether or not it is necessary to pass through an ETC-dedicated lane at the exit according to the toll collection method of the toll road to pass. It is. Furthermore, another object of the present invention is to provide a navigation technique for storing and displaying charge information related to a charge obtained from the outside in association with information such as a travel record obtained from navigation.

  In order to achieve the above object, the invention according to claim 1 is a navigation system for performing road guidance by being mounted on a vehicle, and means for calculating the current position of the vehicle and communicating with the outside of the vehicle. The charge processing means for processing the charge related information related to the charge by ETC of the toll road and the charge related information processed by the charge processing means are stored in association with the travel record which is information related to the travel of the vehicle. Storage means, and means for outputting the stored charge related information and the travel record.

  According to a third aspect of the present invention, the invention of the first aspect is viewed from the viewpoint of a method. In a navigation method for performing road guidance in a vehicle, a step for calculating a current position of the vehicle; A toll processing step for processing toll-related information related to tolls by toll road ETC by communicating with the toll road, and the toll-related information processed by the toll processing step, a travel record that is information about travel of the vehicle, A step for storing in association with each other, and a step for outputting the stored charge-related information and the travel record.

  The invention of claim 5 captures the inventions of claims 1 and 3 from the viewpoint of a recording medium on which navigation software is recorded, and uses a computer to record navigation software for performing road guidance in a vehicle. In the recording medium, the software causes the computer to calculate the current position of the vehicle, communicates with the outside of the vehicle, processes fee-related information related to tolls by ETC on the toll road, and processes the processed fee-related information. And storing the charge related information and the travel record stored in association with a travel record that is information relating to the travel of the vehicle.

  In the above aspect, the charge related information regarding the road use obtained from the outside by the navigation system can be stored and output in association with the travel record such as the current position at that time, so that the charge information can be confirmed reliably at a later date. The travel record is information obtained from navigation by the navigation system, such as the current position, current time, travel distance from the point where the destination is set, travel time, distance to the destination, and the like.

According to a second aspect of the present invention, in the navigation system according to the first aspect, the travel record includes at least a current position of the vehicle calculated at the time when the charge related information is processed.
The invention of claim 4 captures the invention of claim 2 from the viewpoint of a method, and in the navigation method of claim 3, the travel record is calculated at least when the charge related information is processed. It includes the current position of the vehicle.

[2. Action)
The present embodiment configured as described above operates as follows.
[2-1. Guidance based on ETC installation information)
First, in this embodiment, if it is known in advance from the ETC installation information read from the database by the CD-ROM control unit 12 that the ETC facility is located at the toll booth to pass, the ETC approach determination unit 45 Based on the ETC installation information and the current position, it is determined that the vehicle is going to pass through the toll road on the toll road where the ETC equipment is located. In this case, the second guide unit 43 provides ETC-related guidance, such as the fact that there is an ETC facility at the toll booth to be passed, and the lane position such as whether the ETC dedicated lane is on the right or left side.

[2-2. Memory and guidance for new ETC installation information]
However, as ETC is installed at new tollgates one after another due to the spread of the ETC, if the database update cannot keep up, the ETC dedicated lane will be installed even though the ETC dedicated lane is actually installed at the tollgate. A situation occurs in which guidance cannot be made to pass through. In such a case, the ETC installation information indicates that an ETC-dedicated lane was created when actually passing through a toll booth that should have no ETC facilities. Therefore, in the present embodiment, new ETC installation information is stored, and guidance is performed based on the new ETC installation information.

  Here, FIG. 2 shows that an antenna (referred to as a toll booth antenna) A installed on a toll road entrance toll gate and an ETC processing section 13 of the own vehicle C passing through an ETC dedicated lane are wirelessly communicated. It is a conceptual diagram which shows the state which exchanges charge related information, such as entrance information. FIG. 3 is a flowchart showing a processing procedure when the ETC processing unit 13 receives the entrance information in this way at the toll road entrance toll gate that should not have ETC equipment yet in the ETC installation information.

  That is, when the ETC processing unit 13 receives the entrance information at the toll road entrance toll gate that should not have an ETC facility yet in the ETC installation information (step 31), first, the receipt method determination unit 46 The charge collection method (also called the charge method) on the toll road is determined according to whether or not the charge has been charged.

  That is, if it is not charged at the entrance, it is a toll road of the entrance ticketing / acquisition method (step 32), and if it is charged at the entrance, it is a toll road of the simple receipt system, so the additional ETC installation information storage unit 44 The location corresponding to the current location that the ETC equipment is installed at the toll road entrance toll gate together with the entrance ticket issue / exit receipt method (step 33) or the simple receipt method (step 34) Information, that is, stored as additional ETC installation information associated with road information (steps 33 and 34). However, such determination and storage of the toll collection method are not essential, and only the location of the entrance toll gate where the ETC is installed may be stored as ETC installation information.

  From then on, the ETC approach determination unit 45 determines this also when trying to pass the toll road corresponding to the position information stored in the additional ETC installation information storage unit 44 as described above. Here, FIG. 4 is a flowchart showing a processing procedure in the case where guidance regarding ETC is performed based on the ETC installation information stored in the additional ETC installation information storage unit 44.

  That is, when the pre-calculated route to the destination includes a toll road entrance corresponding to the ETC information stored in the additional ETC installation information storage unit 44, the vehicle is being guided along this route. The ETC approach determination unit 45 determines that the host vehicle has come to the stored entrance (step 41).

  At this time, the second guide unit 43 is dedicated to the ETC at the entrance if the charging method is not stored in association with the road information included in the ETC installation information in the additional ETC installation information storage unit 44 (step 42). The user is guided to pass through a lane (also called an ETC dedicated entrance) (step 43). At this time, if the ETC installation information itself does not exist at the entrance of the toll road, only the information that should be entered into the toll road may be guided as in the past.

  If the charging method is also stored in the determination in step 42, guidance is given to pass through the ETC dedicated entrance according to the determination of whether the charging method is the entrance ticket issuing / acquisition method or the simple receiving method (step 44). At the same time (steps 45 and 46), the user is informed of the entrance ticketing / exit receiving method (step 45) or the simple receiving method (step 46).

[2-3. (Exit guidance according to toll collection method)
Further, in the present embodiment, the guidance of the exit according to the fee collection method is performed using the flag of the charge waiting storage unit 47. First, FIG. 5 is a flowchart showing a processing procedure for determining a toll collection method and operating a flag when entrance information is received. That is, as shown in FIG. 2, when the entrance information is received when passing through the entrance of the toll gate (step 51), the toll collection method determination unit 46 determines the toll collection method according to whether or not the fee is charged at the entrance. (Step 52).

  The charge waiting storage unit 47 stores whether or not a fee is charged when passing through the entrance of the toll road where the ETC is installed. Here, when the fee is not charged, the charge waiting storage unit 47 It shall be remembered. That is, if it is not charged when the entrance information is received, it is a toll road of the entrance ticketing / exit receiving method, so the charging waiting storage unit 47 sets the entrance passing charging waiting flag (step 53). On the other hand, if it is charged at the entrance, it is a toll road with a simple toll system, and the entrance passing charge waiting flag is cleared (step 54).

  Here, the entrance waiting billing flag indicates that it should pass through the ETC lane of the exit toll booth (referred to as the ETC exit) because it has passed through the ETC entrance on the toll road but has not been charged yet. In the conventional technology, the role of the flag is to place the pass ticket received by the driver's car in a place where it is easily noticeable.

  Next, FIG. 6 is a flowchart showing a processing procedure in the case of providing guidance regarding the exit according to the state of the entrance pass charging waiting flag. In other words, when the route calculated in advance includes a portion that leads to a general road from a toll road such as an expressway, a point for guiding the exit from the toll road to the general road during guidance according to such a route When the vehicle reaches the vehicle, the ETC approach determination unit 45 detects that it is going through the exit of the toll road based on the current position (step 61).

  In this case, the second guide unit 43 provides guidance regarding whether or not it is necessary to pass through the ETC exclusive lane at the exit of the toll road according to whether or not the fee is charged at the entrance. To the exit. Here, when the passage of the entrance is stored in the charge waiting storage unit 47, the second guide unit 43 guides the user to exit the ETC dedicated lane.

  That is, the second guide unit 43 determines whether or not the entrance passage charge waiting flag of the charge waiting storage unit 47 is set (step 62). (Step 63) Instruction guidance is performed so as to pass through the ETC exclusive exit (Step 64). On the other hand, if the entrance waiting billing flag in the billing waiting storage unit 47 is not set, normal guidance guidance is performed without being limited to the ETC dedicated exit (step 65).

[2-4. Storage and Output of Fee-Related Information] In this embodiment, ETC fee-related information can be stored together with the travel record and output later. Here, the fee-related information processed by the ETC processing unit 13 includes entrance information and fee information. Here, the fee information received by the ETC processing unit 13 from the roadside device is recorded as a travel record (also referred to as travel data). FIG. 7 is a flowchart showing this processing procedure.

  That is, the charge related information storage unit 48 appropriately checks the reception of the charge information (step 71), and when the ETC processing unit 13 receives the charge information, the charge information is converted into travel data that is information related to the travel of the vehicle. The information is stored in association (step 72).

  Here, the travel data is information obtained from navigation by the navigation system. For example, the current position, the current time, the travel distance from the point where the destination is set, the travel time, the distance to the destination, etc. can be freely determined. Here, it is assumed that at least the current position of the own vehicle calculated at the time when the charge related information is processed is included.

  The charge related information and the travel record stored in the charge related information storage unit 48 in this way can be output from the charge related information output unit 49 at any time later.

[3. effect〕
As described above, in the present embodiment, the operation of the second guide unit 43 etc. provides guidance on whether there is an ETC facility at the toll booth to be passed and whether the ETC dedicated lane is on the right side or the left side. For this reason, the driver does not have to make his own judgment as to whether the toll gate to be passed is equipped with ETC facilities or where the ETC dedicated lane is, making it easier to use the ETC and driving safety. The characteristics are further improved.

  Further, in the present embodiment, even if there is no ETC installation information in the navigation system database in advance for a toll road such as an expressway and it is not known in advance that there is an ETC facility, the additional ETC installation information storage unit 44, ETC approach determination When the in-vehicle device is operated at the toll gate entrance by the operation of the unit 45, the second guide unit 43, etc. and receives the ETC entrance information and toll information, the position is stored in association with the coordinates and road information.

  The stored toll road is then guided by voice or display so as to pass through the ETC dedicated lane when included in the calculated route to the destination or when trying to pass the same toll gate. For this reason, the driver can recognize in advance that he / she passes through the ETC exclusive lane, the ETC can be used effectively, and the driving safety is further improved.

  In particular, in the present embodiment, the toll collection method is determined and stored based on whether or not the fee is charged at the entrance by the operation of the toll collection method determination unit 46 and the like, and the user is also notified of the toll collection method. Becomes smoother.

  In this embodiment, the operation of the receipt method determination unit 46, the charging waiting storage unit 47, and the like guides whether it is necessary to pass through the ETC dedicated lane at the exit depending on whether the fee is charged at the entrance.
