  The control unit 10 is configured by, for example, a CPU (Central Processing Unit) and the like, and controls each unit of the navigation device 1. The control unit 10 reads out and executes a dedicated or general-purpose program stored in the storage unit 12 to be described later, thereby performing navigation processing in general (route search processing, map matching processing, etc.), and an entry permission / inhibition information detection unit. It also functions as 10A, right / left turn priority setting unit 10B, and parking lot entrance determination unit 10C. The details of the entry permission / inhibition information detection unit 10A, the right / left turn priority setting unit 10B, and the parking lot entrance determination unit 10C will be described later in the description of the operation of the navigation device 1.

  The position detection unit 11 is configured by, for example, a GPS (Global Positioning System) receiver and a gyro sensor, performs positioning measurement using them, and detects the position of the vehicle on which the navigation device is mounted. The detected position data is output to the control unit 10.

  The storage unit 12 includes, for example, a RAM (Random Access Memory), a ROM (Read Only Memory), a hard disk, and the like. The storage unit 12 reads an external storage medium (for example, a CD (Compact Disc), an MD (MiniDisc), a DVD (Digital Versatile Disc), a memory card, a Blu-ray Disc (Blu-ray Disc (registered trademark), etc.). The storage unit 12 can also temporarily store arithmetic processing data executed by the control unit 10 and can store information received from the center device 3. In addition to the OS and various programs (not shown) for the control unit 10 to operate as the navigation device 1, the unit 12 includes map information 12A, parking lot dynamic information 12B, parking lot static as shown in FIG. Information 12C is stored, and the map information 12A includes image information (including video), audio information, text information, and POI information (Point Of Interest) for displaying a map. Rarely, for example, include a character layer for displaying road link data, road layer having such node data, a background layer for displaying objects on a map, characters such as city name.

  The parking lot dynamic information 12B includes full parking lot information (vacant number information for the entire parking lot, empty number information for each entrance). On the other hand, the parking lot static information 12C includes a parking lot name, parking location coordinates (latitude, longitude, tertiary mesh code, etc.), maximum number of entrances, location coordinates of each entrance, right turn entry flag for each entrance, Capacity, vehicle restrictions (presence of parking space for each model, etc.), equipment status (presence of disabled persons, presence of barrier-free elevators, slopes, etc., presence of women-only space, presence of EV car-dedicated spaces, toilets Information indicating presence / absence, presence / absence of motorcycle), business hours, settlement means (cash, credit, etc.), and the like. Parking area dynamic information 31A and parking area static information 31B stored in the storage unit 31 of the center apparatus 3 are stored, and the parking area dynamic information 12B and the parking area static information 12C of the navigation apparatus 1 are It can be acquired at any time by making a search request to the center apparatus 3, and can be updated, newly added, or deleted.

  The display unit 13 is configured by, for example, a display on which a touch panel is disposed and displays a video signal under the control of the control unit 10. In addition, in the case of a display in which a touch panel is provided in an overlapping manner, it also functions as an operation input unit 15 described later.

  The audio output unit 14 includes, for example, an amplifier and a speaker, and outputs an audio signal under the control of the control unit 10.

  The operation input unit 15 includes, for example, an input interface such as an operation button, and various instructions (for example, route guidance instruction, parking lot search instruction, right turn / left turn priority setting, etc.) by the operation of the driver and the passenger of the vehicle. Entered. Note that the operation input unit 15 may be configured by a touch panel so that an instruction can be given by a software button.

  The communication unit 16 enables wireless communication with the roadside apparatus 2 and includes a communication interface that enables wireless communication using, for example, DSRC, Bluetooth (registered trademark), WiMAX, or the like. In addition to the communication unit 16, the navigation device 1 includes traffic information transmitted by radio wave beacons, optical beacons, or FM multiplex broadcasting (congestion information indicating the degree of congestion on roads, traffic regulation information indicating road closure times, etc.). ) May be included (not shown).

  FIG. 2 is a flowchart showing a parking lot setting process executed by the navigation device 1 shown in FIG. As a premise of the processing of FIG. 2, it is assumed that the planned route to the destination has already been searched and the driver of the vehicle has operated the operation input unit 15 to set the right turn / left turn priority. .

  When the parking lot setting process is started in the navigation device 1 (START), the parking lot dynamic information 31A and the parking lot static information 31B stored in the center device 3 are transferred to the navigation device 1 via the roadside radio device 2. Are stored in the storage unit 12 as parking lot dynamic information 12B and parking lot static information 12C (S1). That is, in the navigation device, the parking lot information is downlinked from the center device 3 to the navigation device 1 via the roadside device 2 in S1. In addition, traffic information near the parking lot may also be downlinked.

  The parking lot setting process referred to in S1 is, for example, a setting process for automatically searching for a parking lot near the vehicle when a vehicle equipped with the navigation device 1 enters the communication area of the roadside wireless device 2. Alternatively, when the vehicle on which the navigation device 1 is mounted enters the communication area with the roadside wireless device 2, DSRC communication is started, and parking lot search is performed according to the driver's instruction.

  The parking lot information downlinked in S1 is displayed on the display unit 13 (S2). FIG. 3 is a diagram showing an example of a screen displayed on the display unit 13 in S2 of FIG. In FIG. 2, parking lot information existing around the vehicle is displayed. In the screen example of FIG. 3, a parking lot name and full / vacant information of the parking lot are displayed.

  The control unit 10 of the navigation device 1 sets a timer (S3). This timer is for automatically erasing the list of parking lot information output to the display unit 13 in S9 described later. And the control part 10 determines whether the parking lot currently displayed on the display part 13 was selected (S4). When the parking lot is selected, the control unit 10 as the right / left turn priority setting unit 10B and the parking lot entrance determination unit 10C reads the right / left turn priority setting set by the driver (S5), An entrance determination process (S6) described later is executed to clear the timer (S8). On the other hand, when it is determined that the parking lot is not selected in S4, the control unit 10 repeats the determination in S4 until it is determined that the timer set in S3 has timed out (S7), and is determined to be timed out. If so, the timer is cleared (S8). When the count of the timer is cleared in S8, the control unit 10 deletes the list of parking lot information output to the display unit 13 from the display unit 13 (S9), and ends the parking lot setting process (END).

  Of the processes shown in FIG. 2, the processes related to the timers in S3, S7, and S8 are those in which the navigation device 1 has an interface that exclusively outputs a list of parking lot information, or parking as shown in FIG. This may be omitted if the user can give an instruction to erase these lists by operating the operation input unit 15 while displaying the list screen of the parking lot information.

  FIG. 4 is a flowchart showing details of the entrance determination process shown in S6 of FIG. As a premise of the processing shown in FIG. 4, it is assumed that the parking lot static information 12 </ b> C is downlinked from the center device 3 and stored in the storage unit 12. The control unit 10 as the parking lot entrance determination unit 10C refers to the storage unit 12 with reference to the parking lot entrance information selected in S4 of FIG. 2, and sets the maximum number of entrances of the selected parking lot in the variable N. (S11). The control unit 10 sets 1 as an initial value to the variable i (S12). The control unit 10 lists the entrances of the parking lots in order from the planned route (S13).

  And the control part 10 determines whether it will approach by right turn, when selecting the entrance of the entrance list i-th as an entrance and performing route guidance (S14). When it is determined that the entrance i-th entrance does not enter the right turn (NO in S14), that is, the control section 10 means that the entrance i-th entrance enters the left turn. The entrance is set as a parking lot entrance (S17).

  On the other hand, when it is determined in S14 that the i-th entrance of the entrance list is selected in S14, the control unit 10 determines that a right turn is to be entered from the planned route (YES in S14). It is determined whether a right turn can be entered (S15). Specifically, the control unit 10 as the entry permission / inhibition information detection unit 10A refers to the right turn entry permission flag at the entrance of the i-th parking lot included in the parking lot static information 12C stored in the storage unit 12. Judge whether or not to enter right turn. This is because, for example, a case where a median strip or the like is present in front of the parking lot entrance and it is not possible to enter the vehicle by making a right turn.

  Then, when it is determined that a right turn approach is possible (YES in S15), the control unit 10 further determines whether or not the driver's left turn priority is set based on the information read in S5 of FIG. (S16). If the control unit 10 determines in S16 that the left turn priority setting is not made (NO in S16), there is no problem in entering the i-th entrance of the entrance list by making a right turn. Set as mouth (S17).

  On the other hand, when the control unit 10 determines that the i-th entrance of the entrance list cannot enter the right turn (NO in S15), it checks whether i is equal to N, that is, checks all entrances of the entrance list. (S18), if it is determined that they are not equal, 1 is added to i (S19), and the process returns to S14 to investigate the next entrance. On the other hand, if it is determined that i is equal to N in S18, the control unit 10 changes the planned route so as to enter the entrance of any parking lot in the entrance list by making a left turn (S20), and the process of S12 Return to.

(Modification 1 of FIG. 4)
FIG. 5 is a flowchart showing a modification of the process of FIG. Since the process of S16 is different from the process of FIG. 4, only the different part will be described, and the description of the other identical parts will be omitted. In the processing shown in FIG. 5, information indicating the congestion status of the lane in front of the entrance of the parking lot and in the opposite direction to the approach direction (that is, the opposite lane) is acquired in advance. In consideration of this, the entrance of the parking lot is determined. In addition, when the communication unit 16 of the navigation device 1 also functions as a VICS receiving unit (not shown), the information indicating the congestion state may be acquired from the received VICS information, or the center device When the information indicating the congestion situation near the parking lot is included in the third parking lot dynamic information 12 </ b> B, the information may be received and acquired via the roadside apparatus 2.

  The control unit 10 as the parking lot entrance determination unit 10C determines that the entrance list i-th entry can be entered in the right turn in the determination of whether or not the entrance entry i-th entry in S15 can enter the right turn. It is determined whether or not the traffic is congested in the oncoming lane near the entrance (S16A). If it is determined that the traffic is not congested (NO in S16A), there is no problem in entering a right turn. The i-th entrance is set as a parking lot entrance (S17). On the other hand, if the control unit 10 determines that the traffic is congested in the oncoming lane near the i-th entrance of the entrance list (YES in S16A), does the control unit 10 have one lane at the place where it is scheduled to turn right? It is further determined whether or not (S16B). And when the control part 10 determines with the number of the own lanes of the place of the right turn plan being one (NO in S16B), since there are a plurality of lanes in the lane to be entered, It is estimated that there is a right turn lane and a straight lane, and it is determined that there is a low possibility of causing trouble to the following vehicle for a right turn, and the entrance of the entrance list i-th is set as a parking lot entrance (S17). On the other hand, if it is determined that the number of lanes at the place where the vehicle is scheduled to turn right is one (YES in S16B), the control unit 10 is likely to cause trouble for the following vehicle. Since it is not appropriate to use the entrance of No. as a parking lot entrance, the process proceeds to S18. In addition, it is determined whether or not the road for entering the parking lot is one-way. If the road is one-way, the entrance i-th entrance is set as a parking entrance (S17). If it is not one-way, the determination in S16A may be performed. As a result, when it is determined that the vehicle is one-way, there is no oncoming lane, so there is no need to grasp the congestion status of S16A. Note that, in the case of a road where information indicating the congestion state cannot be acquired, it may be determined only whether or not the road is one-way instead of the process of S16A.

(Modification 2 of FIG. 4)
FIG. 6 is a flowchart showing a modification of the process of FIG. 6 differs from the process of FIG. 4 only in the process of S20, only the different parts will be described, and the description of the other identical parts will be omitted. In the process shown in FIG. 6, in the process corresponding to S20, the planned route is not changed so that a left turn can be entered at any of the entrances, but the conditions of the parking lot selected by the user (for example, the parking fee is low). Other parking lots that are very close to the parking lot, a parking lot that matches the parking lot usage time, a parking lot that is close to the position of the vehicle, etc.) are set again (S20A). Note that, after the process of S20A, the control unit 10 shifts to S11 instead of S12, unlike the process of FIG. This is because the target parking lot is changed and the maximum number N of entrances needs to be set again. This makes it possible to search for a parking lot that is very close to the parking lot conditions selected by the user and can be entered by making a left turn. In the process of S20A, if possible, the planned route may be changed so as to bypass and guide the surrounding roads so that the user can enter with a left turn.

  As described above, according to the navigation device 1 and the navigation method executed by the navigation device 1, the information is obtained from the center device 3 that provides the parking lot dynamic information 31 </ b> A and the parking lot static information 31 </ b> B via the roadside device 2. The information received and received by the communication unit 16 (reception unit) is stored in the storage unit 12 as parking lot dynamic information 12B and parking lot static information 12C, and the information stored in the storage unit 12 is transferred to the entrance of the parking lot. Entry right / left turn priority setting that gives priority to right turn or left turn when entering the parking lot entrance is detected by the entry allowance information detection unit 10A, which indicates whether the vehicle can enter by right turn or left turn. It is a case where it is possible to enter by the right or left turn to the entrance of the parking lot from the entry availability information detected by the entry availability information detection unit 10A performed by the setting unit 10B However, if the opposite approach method is preferentially set in the setting of the right turn / left turn priority setting unit 10B, the parking lot where the parking lot entrance determination unit 10C can enter by the preferentially set entry method. If the driver wants to avoid entering the parking lot by making a right turn, the right turn / left turn priority setting unit 10B gives priority to the left turn. By performing the setting, it is possible to preferentially search and guide a parking lot that can be entered by turning left. In particular, in this navigation device 1, when one parking lot has a plurality of entrances, it is possible to preferentially select and guide the entrance of the parking lot that can be entered by making a left turn. This is more preferable for the driver.

  In addition, the parking lot dynamic information 12B and the parking lot static information 12C include information indicating the congestion status of roads near the parking lot or a right turn entry permission flag (information indicating road traffic regulation), and the parking lot entrance decision is made. When it is determined that the lane facing the lane that is scheduled to enter the parking lot entrance is not congested (NO in S16A), the unit 10C sets the entrance to the parking lot. It is decided to be the entrance when entering. This makes it possible to determine the entrance of the parking lot as an entrance only when the lane opposite the lane that is scheduled to enter the parking lot entrance is not crowded. It is possible to guide to an appropriate parking lot.

  The above embodiment is an example of the embodiment of the present invention. However, the present invention is not limited to this, and various modifications and changes can be made without departing from the scope of the invention. For example, the right turn / left turn priority setting unit 10B has determined the operation input unit 15 based on information set by the driver or the passenger, but also specifies the driver who drives the vehicle. You may make it perform the setting which gives priority to entering by a right turn or a left turn automatically according to the specified driver | operator. For example, the right turn / left turn priority setting unit 10B includes: (1) a method of specifying an individual from music information to be played and music information previously associated with the individual; (2) a method of specifying an individual by voice identification / eyeprint; (3) A method for identifying an individual by comparing the load (weight) applied to the driver's seat of the vehicle with a pre-recorded individual's weight, (4) a method for identifying by the habit of driving method (for example, accelerator Individuals are identified by some method, such as differences in timing and timing when stepping on the brake, differences in engine speed when changing gears in MT cars, differences in timing of turning winkers, differences in driving speed against legal speed, etc.) The priority setting of the right turn / left turn previously associated with the specified individual may be read. As a result, right / left priority is set according to the driver of the vehicle, and it is possible to guide to an appropriate parking lot in consideration of the skill, characteristics, etc. of the driver.

  In addition, in this embodiment, the case where it is desired to prioritize the left turn over the right turn on the premise of the traffic rule of Japan (left-hand traffic) is explained, but even if the reverse traffic rule is adopted (right-hand traffic) Similar effects can be obtained. That is, when the right-hand traffic rule is adopted, the same effect as in the present embodiment can be obtained if the right turn / left turn priority setting unit 10B performs the setting for giving priority to the right turn over the left turn.

  Moreover, the function of each structural block which the navigation apparatus 1 which concerns on embodiment mentioned above has may be implement | achieved all or one part by software, or at least one part may be implement | achieved by hardware. That is, a program (not shown) stored in the storage unit 12 that functions as the above-described navigation device 1 functions as an entry permission / inhibition information detection unit, a right / left turn priority setting unit, and a parking lot entrance unit. It is also possible to play.

  The present invention can be used for, for example, a device that can navigate a vehicle to a destination or a portable information processing device.
