  The navigation system 400 includes an operation unit 410, a measurement unit 430, an output unit 440, a recording unit 450, a first communication unit 470, a second communication unit 480, and a control unit 490 (see FIGS. 2 and 3).

  The operation unit 410 is a device that sends a command to the control unit 490 by a user operation such as a remote controller. In the present embodiment, the remote controller is used as a remote controller. However, the output unit 440 may have a touch panel, and may be operated by touching the output unit 440 or around the output unit 440. The operation may be performed by arranging keys.

  The measurement unit 430 is a device that measures the position of the vehicle such as a GPS and an angular velocity sensor.

The output unit 440 displays the vehicle position on a map based on the vehicle position measurement information. Moreover, information on the n-th gate 210A _n at a predetermined timing (see step S51 in FIG. 6), is guided in one of the guide modes of the first to third guide mode M1 to M3. Information guidance regarding the first n gate 210A _n, the n beacons 260A new received from _n the n-th gate information IG _n, or n-th with the old second n gate information IG _n or map data recorded in the recording unit 450, This is performed based on the fixed gate information FIG _n .

In the display of the n gate 210A _n by the output unit 440, a layout is set according to the number of toll booth gate of the n gate 210A _n included in the n-th gate information IG _n (number of gates).

The new n-th gate information IG _n and the old n-th gate information IG _n are both received from the n-th beacon 260A _n and recorded in the recording unit 450 (or temporarily stored in the internal memory of the control unit 490). It is distinguished according to the information acquisition time. The new n-th gate information IG _n is gate information acquired through the n-th beacon 260A _n in the past less than a certain time T1 from the present time. The old n-th gate information IG _n is gate information acquired through the n-th beacon 260A _n in the past for a certain time T1 from the present time. The n-th fixed gate information FIG _n included in the map data recorded in the recording unit 450 is the gate information of the _n- th gate 210A _n included in the map data used by the navigation system 400.

The fixed time T1 is set in consideration of the time until the vehicle that has passed through the n-th beacon 260A _n moves to the n-th gate 210A _n that is ahead by the first distance d1 or the second distance d2.

The new n-th gate information IG _n is used for specifying a recommended gate described later. The old n-th gate information IG _n and the gate information included in the map data are not used for specifying the recommended gate. FIG. 1 shows a form in which the _n- th gate information IG _n is displayed in the output unit 440. Further, the output unit 440 performs voice guidance such as route guidance using a voice output device (not shown).

The recording unit 450 is a recording medium that records map data having the _first to Nth fixed gate information FIG _{1 to} FIG. _N , but the type of the recording medium is not limited. In this embodiment, a hard disk is used as a recording medium. The recording unit 450 records the new n-th gate information IG _{n along} with the gate information acquisition time (the time received by the first communication unit 470) in addition to the map data. At this time, the old n-th gate information IG _n is deleted.

When the n-th gate information IG _n cannot be acquired due to a problem on the transmission side or the reception side when passing through the n-th beacon 260A _n , the gate information is stored using the n-th gate information IG _n acquired in the past. Display is performed. If no _n- th gate information IG _n has been acquired in the past, the gate information is guided using the _n- th fixed gate information FIG _{n included} in the map data used as the navigation system.

The first to Nth fixed gate information FIG _{1 to} FIG _N are not updated until the map data is updated.

The first communication unit 470 is a communication device that transmits and receives signals from optical beacons and radio beacons provided on the road. Light beacons, on the basis of a signal from a radio beacon, the navigation system 400 is to acquire the congestion information, in the present embodiment, further also acquires the n gate information IG _n.

The second communication unit 480 is a DSRC (Dedicated).
An ETC (Electronic Toll Collection System) vehicle-mounted device that uses Short Range Communications (Short Range Communication), and communicates with radio equipment (DSRC base stations, roadside devices) installed on the roadside such as toll gates. Based on the communication with the roadside device, the navigation system 400 performs toll road charging processing.

The control unit 490 controls each unit. The control unit 490 performs route search based on the route setting performed using the operation unit 410. The control unit 490 determines whether or not the n-th gate information IG _n recorded in the recording unit 450 is the latest, and if it is the latest, the route set by the route search and the availability of ETC. Recommended based on the situation (whether or not the second communication unit 480 is attached to the navigation system 400 and whether or not the billing card is properly inserted in the second communication unit 480) and the nth gate information IG _n The gate to be determined is determined and output (display and voice guidance).

For example, the n-th gate 210A _n, when the state shown in FIG. 1, in order to use the ETC corresponding vehicle-only gate, it is necessary to use the tollgate right or the left end of the tollgate gate, tollgate In accordance with the route after exiting, guide which toll gate is to be used (if the route turns right after exiting the toll gate, use the ETC compatible vehicle dedicated gate on the right side Guidance) The same applies to vehicles not compatible with ETC.

The control unit 490 guides the passable gate based on the n-th gate information IG _n (or the n-th fixed gate information FIG _n ) and the availability status of the ETC in-vehicle device of the vehicle on which the navigation system 400 is mounted. Specifically, in a state where the ETC on-board device is available (a state where the second communication unit 480 is attached to the navigation system 400 and a charging card is properly inserted in the second communication unit 480). In this case, all of the ETC compatible vehicle dedicated (ETC) gate and the ETC compatible vehicle / non-compatible vehicle common (ETC / general) gate are guided as passable gates. In the case where the ETC on-board device is not usable (a state where the second communication unit 480 is not attached to the navigation system 400 or a state where a billing card is not properly inserted into the second communication unit 480), All the gates that are in use and dedicated to ETC non-compliant vehicles (general) and ETC compatible vehicles / non-compliant vehicle shared (ETC / general) gates are guided as passable gates. Since there may be a plurality of passable gates, it is desirable to use the display of the output unit 440 for illustration, but guidance may be provided by voice.

The internal memory of the control unit 490 (not shown) temporarily stores the n gate information IG _n.

Next, the flow of generating the nth gate information IG _n and transmitting it to the nth beacon 260A _n will be described using the flowchart of FIG. Generation of n-th gate information IG _n is performed from time to time.

In step S11, the distribution of the n gate information IG _n is started, in step S12, the n-th gate status detection unit 230A _n, gate type set for each tollgate gate in the n-th gate 210A _n, And the availability status is detected. In step S13, the n-th gate information transmitting unit 250A _n, gate type set for each tollgate gates detected at the n gate status detection unit 230A _n, and generates the n-th gate information IG _n based on the availability status and, in step S14, the n-th gate information IG _n, and transmits to the n beacons 260A _n.

Next, the navigation system 400, the flow of receiving the n-th gate information IG _n, will be described with reference to the flowchart of FIG.

When the vehicle equipped with the navigation system 400 passes through the _n- th beacon 260A _n that transmits the _n- th gate information IG _n , the n-th gate between the first communication unit 470 and the n-th beacon 260A _n in step S31. Transmission / reception of information IG _n is started. In step S32, it is determined whether the recording unit 450 can write the n-th gate information IG _n (whether there is a storage area). If it is, at step S33, a new n-th gate information IG _n received from the n beacons 260A _n is recorded in the recording unit 450 together with the gate information acquisition time, it proceeds to step S34. At this time, the n-th gate information IG _n recorded in the past is deleted. If not, the n-th gate information IG _n newly received from the n-th beacon 260A _n is temporarily stored in the internal memory of the control unit 490 in step S34.

Next, the flow of performing gate information guidance at the output unit 440 based on the received n-th gate information IG _{n and the} like will be described using the flowchart of FIG.

Guidance is provided at the timing when the navigation system 400 guides information related to the n-th gate 210A _n such that the vehicle on which the navigation system 400 is mounted passes a point in front of the n-th gate 210A _n by a third distance d3. The procedure is started (step S51). The third distance d3 is set shorter than the first and second distances d1 and d2.

In step S52, it is determined whether or not the n-th gate information IG _n recorded in the recording unit 450 has been recorded in the past less than a predetermined time T1 from the present time. If the nth gate information IG _n recorded in the recording unit 450 is the latest information, the process proceeds to step S53, and is recorded in the past for a certain time T1 or more. If it is recorded in step S56, the n-th gate information IG _n recorded in the recording unit 450 is not the latest information, and the process proceeds to step S56.

In step S53, the latest gate information is read out. That is, the n gate information IG _n temporarily stored in the internal memory of the control unit 490 is read. The same n-th gate information IG _n is recorded in the recording unit 450, but it is desirable to read from the internal memory having a high reading speed.

In step S54, the control unit 490 determines whether the route set by the route search, the ETC on-vehicle device availability status (whether the second communication unit 480 is attached to the navigation system 400, and the second communication unit 480 is charged). Based on the n-th gate information IG _n , the recommended gate is specified. The flow for specifying the recommended gate will be described later (see FIG. 9). If no route is set, recommended gate identification is not performed.

  When the ETC on-board device is available (when the second communication unit 480 is attached to the navigation system 400 and the billing card is properly inserted into the second communication unit 480), it is used. A toll gate that is close to the set route is one of the toll gates of ETC-compatible vehicles (ETC) gates and ETC-compatible vehicles / non-compatible vehicles (ETC / general) gates. Identified as

  In the case where the ETC on-board device is not usable (a state where the second communication unit 480 is not attached to the navigation system 400 or a state where a billing card is not properly inserted into the second communication unit 480), There is a toll gate that is close to the set route among the toll gates that are in use and are dedicated to ETC non-compliant vehicles (general) gates and ETC compatible vehicles / non-compliant vehicle shared (ETC / general) gates Identified as a recommended gate.

In step S55, the first guiding mode M1, on the basis of the new n-th gate information IG _n like, the output unit 440 performs a gate condition information. That is, the display unit of the output unit 440, in a state that shows the recommended gate specified, displays the gate status of the n gate 210A _n (gate type, and availability status). FIG. 2 shows a form in which a toll gate dedicated to an ETC compatible vehicle located at the right end is displayed as a solid line arrow as a recommended gate. In addition, the voice output device of the output unit 440 is used to guide gate status guidance, particularly recommended toll gates. The guidance by the voice output device is, for example, “the right-hand ETC-compatible vehicle gate is convenient”.

If there is no branch within a certain distance after passing through the n-th gate 210A _n on the set route, the recommended gate is not specified, and therefore the recommended gate is not indicated even in the first guidance mode M1. in state (the state shown in passable gate to be described later), a gate status of the n gate 210A _n are guided.

In the display of the gate status of the n-th gate 210A _n in the first guidance mode M1, a vehicle equipped with the navigation system 400 can pass based on the availability status of the ETC on-board device and the new n-th gate information IG _n. The toll gate (passable gate). When the vehicle navigation system 400 is mounted is usable state ETC OBE, ETC corresponding vehicle-only gate in the use of the n-th gate 210A _n, and ETC corresponding vehicle / non-compliant vehicle shared gate can pass gate , and the if it is ETC unavailability state, the n-th gate 210A _n ETC incompatible vehicle only gate in use, and ETC corresponding vehicle / non-compliant vehicle shared gate can pass through the gate. In the present embodiment, the passable gates that do not overlap with the recommended gates are indicated by dotted arrows (see FIG. 2).

In step S56, it is determined whether _n- th gate information IG _n is recorded in recording unit 450 or not. If it is recorded, the process proceeds to step S57. If it is not recorded, the process proceeds to step S59.

In step S57, past gate information is read. That is, the nth gate information IG _n recorded in the recording unit 450 is read out.

In step S58, the second guidance mode M2, on the basis of the old first n gate information IG _n like, the output unit 440 performs a gate condition information. That is, the display unit of the output unit 440, a state which does not show availability status Recommended gates and each gate is identified, and in the state shown the gate information acquisition time, gate status of the n gate 210A _n (gate type ) Is displayed. FIG. 7 shows a form for displaying the gate status (no use / non-use indication) and the time information when the n-th gate information IG _n is acquired. Not show the availability status of each gate has a first n gate information IG _n to be used for guiding, because there is a usability status of the current of each gate can be different.

In the display of the gate status of the n-th gate 210A _n in the second guidance mode M2, a vehicle equipped with the navigation system 400 can pass based on the availability status of the ETC on-board device and the old n-th gate information IG _n. The toll gate (passable gate). When the vehicle navigation system 400 is mounted is usable state ETC OBE is a n-th gate 210A _n ETC corresponding vehicle-only gate, and ETC corresponding vehicle / non-compliant vehicle shared gate can pass gates, If it is ETC unavailability state, ETC non-compliant vehicle dedicated gate of the n gate 210A _n, and ETC corresponding vehicle / non-compliant vehicle shared gate can be gate passage. However, the availability status of each gate is not reflected. In the present embodiment, the passable gate is indicated by a dotted arrow (see FIG. 7).

In step S59, the gate information with map data recorded in the recording unit 450 corresponding to the n gate 210A _n it is is read.

In step S60, in the third guidance mode M3, the output unit 440 provides gate status guidance based on the nth fixed gate information FIG _{n and the} like included in the map data. That is, the display unit of the output unit 440 displays the gate status (gate type) of the n-th gate 210A _{n in} a state indicating that the _n- th fixed gate information FIG _n included in the map data is present. FIG. 8 shows a form of displaying the gate status (no availability display), the type of gate, and the gate information included in the map data. The reason why the availability of each gate is not shown is that the n-th fixed gate information FIG _n used for guidance may be different from the current availability status of each gate.

In the third guidance mode M3, in the display of the gate status of the n-th gate 210A _n , the navigation system 400 is mounted based on the availability status of the ETC on-vehicle device and the n-th fixed gate information FIG _n included in the map data. Guide the toll gate (passable gate) through which vehicles can pass. When the vehicle navigation system 400 is mounted is usable state ETC OBE is a n-th gate 210A _n ETC corresponding vehicle-only gate, and ETC corresponding vehicle / non-compliant vehicle shared gate can pass gates, If it is ETC unavailability state, ETC non-compliant vehicle dedicated gate of the n gate 210A _n, and ETC corresponding vehicle / non-compliant vehicle shared gate can be gate passage. However, the availability status of each gate is not reflected. In the present embodiment, the passable gate is indicated by a dotted arrow (see FIG. 8).

In step S59, when the map data recorded in the recording unit 450 does not include the n-th fixed gate information FIG _n corresponding to the n-th gate 210A _n , the guidance in the third guidance mode M3 is not performed. However, if the n-th gate information IG _n can be acquired when passing through the n-th beacon 260A _n , the gate status can be guided in the first guidance mode M1 or the second guidance mode M2, and therefore the recording unit 450 does not necessarily have the map data as the map data. It is not necessary to have the n fixed gate information FIG _n . Thus, it is possible to reduce the information acquisition operation for obtaining the first through N fixed gate information FIG ₁ ~FIG _N as the map data, it is possible to reduce costs of the map data creating companies.

  Next, a flow for identifying a recommended gate will be described with reference to the flowchart of FIG.

In step S71 (step S54 in FIG. 6), the specific recommendations gate is started, in step S72, the if there is a branch after the n-th gate 210A _n passes on the set route, the same as the direction in which the branch It is determined whether there is an ETC-compatible dedicated gate in use or a non-ETC-compatible dedicated gate on the side. If there is no branch within a certain distance after passing through the nth gate 210A _n on the set route, the recommended gate is not specified.

If the ETC on-board device is available (when the second communication unit 480 is attached to the navigation system 400 and a billing card is properly inserted into the second communication unit 480), the step is performed. in S72, it is determined if there is a branch within the n predetermined distance gate 210A _n after passing on the set route, whether there is ETC corresponding dedicated gate in use on the same side as the direction in which the branch is .

In the case where the ETC on-board device is not usable (a state where the second communication unit 480 is not attached to the navigation system 400 or a state where a billing card is not properly inserted into the second communication unit 480), At step S72, the if there is a branch within the n predetermined distance gate 210A _n after passing on the set route, whether there is ETC incompatible dedicated gate in use on the same side as the direction in which the branch is determined Is done.

  If there is a dedicated gate, the process proceeds to step S73; otherwise, the process proceeds to step S74.

  In step S73, a recommended gate is identified from dedicated gates in use on the same side as the branching direction. Specifically, a dedicated gate located at a distance closest to the branching direction (a dedicated gate on the right side if branching to the right direction) is selected.

However, in this particular, in the detection of the n gate status detection unit 230A _n, in addition to the gate type and gate availability status, detecting the congestion status of each gate on the basis of the congestion, less congested degree only gate May be specified as a recommended gate.

In step S74, the if there is a branch after the n-th gate 210A _n passes on the set route, whether there is ETC corresponding vehicle / non-compliant vehicle shared gate in use on the same side as the direction in which the branch is determined Is done.

  If there is a shared gate, the process proceeds to step S75; otherwise, the process proceeds to step S76.

  In step S75, a recommended gate is specified from the shared gates in use on the same side as the branching direction. Specifically, the common gate that is closest to the branching direction (the common gate on the right side in the case of branching to the right) is selected.

However, in this particular, in the detection of the n gate status detection unit 230A _n, in addition to the gate type and gate availability status, detecting the congestion status of each gate on the basis of the congestion, less common gate of congestion degree May be specified as a recommended gate.

  In step S76, a recommended gate is specified from among the dedicated gate and shared gate in use. Specifically, a dedicated gate or shared gate that is closest to the branching direction (a dedicated gate or shared gate on the right side in the case of branching to the right) is selected.

However, in this particular, in the detection of the n gate status detection unit 230A _n, in addition to the gate type and gate availability status, detecting the congestion status of each gate on the basis of the congestion, less congested degree only gate Alternatively, a shared gate may be specified as a recommended gate.

In the present embodiment has described the embodiment using a beacon transmission and reception of the n-th gate information IG _n first communication unit 470 (VICS (registered trademark) receiver) is installed in the traveling direction before the n-th gate 210A _n You may perform using the roadside machine and the 2nd communication part 480 (ETC onboard equipment).

If the beacon and the first communication unit 470 are used, the vehicle having the navigation system 400 has the second communication unit 480 (whether the second communication unit 480 is attached to the navigation system 400).
