Description

  TECHNICAL FIELD The present invention relates to a navigation device that supports vehicle road guidance, and in particular, a navigation device guidance display method in a multi-lane roadway having a special lane in which an access permission area with a general lane such as a car pool lane is specified. About.

  Some multi-lane roads such as highways have a traveling lane that allows a specific vehicle to pass preferentially for traffic jam countermeasures and emergency response. A typical example is a carpool lane or a high-occupancy vehicle lane (HOV lane) used in US freeways. The car pool lane is a special lane that allows only vehicles with two or more passengers (referred to in this document as HOV cars) in certain times of day when traffic jams are permitted. By setting up special lanes, we recommend carpooling, reduce traffic congestion and promote environmental measures.

  In car pool lanes, it is common to restrict entry and exit areas from general lanes in order to ensure the safety of driving, and lane changes between general lanes are not allowed in such areas. Doing so is prohibited. FIG. 1 illustrates this, and the car pool lane is divided by road surface paint (which may be a physical separation zone) such as a general lane and a white line, a yellow line, or a combination of a white line and a yellow line. The vehicle is permitted to change lanes only in an access permission area provided at an appropriate interval in the middle of the vehicle. Therefore, when a vehicle traveling in the car pool lane exits from the expressway, the vehicle moves from the entrance / exit permission area of the car pool lane to the general lane, and then exits from the intended expressway exit.

  For this reason, it is important for drivers traveling in the car pool lane which exit area of the car pool lane is required and efficient in order to exit from the intended expressway exit. It is a serious concern.

  Conventionally, there are a plurality of navigation devices that contribute to such a purpose, and there is one that informs the driver of the entry / exit permission area of the car pool lane in advance according to the traveling position of the vehicle (Patent Documents 1 and 2). For example, FIG. 5 of the document 2 discloses a car pool lane exit that is displayed in parallel with a highway exit on a display screen of a navigation device, and guides and guides it as necessary.

  However, in the technique disclosed in the previous document, it is clear which car pool lane exit should be used to exit from the intended expressway exit, but the relative positional relationship between them, that is, the car pool lane exit. Since the mileage from the expressway to the expressway exit is unknown, there is a drawback that it is difficult for the driver to consider the arrival time to the destination. In addition, if there is only one expressway exit for multiple carpool lane exits, the same expressway exit guidance will be provided alongside the different carpool lane exit indications.

  The bus interface 20 includes a detection signal from a self-contained navigation sensor (for example, a vehicle speed sensor, an acceleration sensor, a gyro sensor, etc.), a signal indicating on / off of parking, a signal indicating on / off of a direction indicator, The image signal and the like are received and provided to the control unit 122. As will be described later, the in-vehicle camera 22 is used to capture an image for identifying the traveling lane of the vehicle. The VICS receiver 40 receives road traffic information distributed from the VICS center side by optical beacon, radio wave beacon, FM multiplex broadcasting, etc., and provides it to the control unit 122.

  The input unit 50 includes an operation panel 52 that enables input by touching the display 92, a voice input unit 54 that enables input by voice, and a remote controller 56. The storage unit 70 stores road map data necessary for navigation. The road map data includes link data for identifying roads, node data for identifying intersections, facility data for identifying POIs such as facilities, and administration for identifying boundaries or ranges of administrative divisions of municipalities. Information about sections, information indicating the correspondence between VICS link information and link data included in road map data, and the like are included.

A self-vehicle position calculation program 104 to be calculated, a route search program 106 for searching for an optimal route from the vehicle position and other starting positions to the destination, and the searched route information and vehicle travel information are displayed on the display 92. For example, a travel guidance presentation program 108 that configures voice data to be output from the voice output unit 80.

  The data memory 110 is searched by the road traffic information 112 received by the VICS receiver 40, the road map data 114 around the vehicle position read from the storage unit 70, the calculated vehicle position information 116, and the route search program 106. Guidance route information 118, travel lane information 120 detected by the travel lane detection program 108, and the like are stored.

  FIG. 3 is a functional block diagram of the travel guidance presentation program 108 of the present embodiment. The travel guidance presentation program 108 acquires road information for the vehicle position from the road map data 114, analyzes the road information acquisition / analysis unit 130 for analysis, and the image data from the in-vehicle camera 22, and determines that the travel lane of the vehicle is a car pool. A traveling lane detecting unit 132 that detects whether or not the vehicle is on a lane, a determining unit 134 that determines whether or not the vehicle is a HOV car that can use a car pool lane, the analyzed road information, a traveling lane, and an HOV car. A route calculation unit 136 that calculates an optimum guidance route based on the determination information, a display screen configuration unit 138 that configures guidance information to be displayed on the display 92 based on the acquired and calculated travel information, and similarly A voice guidance generation unit 140 that generates voice information output from the speaker 82 based on the running information is included.

  The road information acquisition / analysis unit 130 acquires and analyzes road information for the vehicle position from the road map data 114, and in particular, in relation to the present invention, the information to be analyzed includes information on the target road of the map data. Car pool lane information is included. As an example, the road map data 114 includes, for each map data map leaf divided on the plane matrix, link information representing roads included therein and node information representing intersections and serving as connection points of links. In addition, each link information includes a flag indicating whether it is a general road or a highway, and a flag indicating whether it is a highway with a car pool lane, as well as location information of the access permitted area. ing. However, the car pool lane may be stored as link information different from the general lane of the expressway, and the entry / exit permission area of the car pool lane may be stored as node information connecting the link of the car pool lane and the link of the general lane. .

  The traveling lane detection unit 132 analyzes the image of the in-vehicle camera 22 on the highway having a car pool lane, and determines whether or not the vehicle is traveling on the car pool lane. The in-vehicle camera 22 is installed, for example, on the rear surface of the room mirror, and can capture the front of the traveling road surface. Carpool lanes are usually equipped with indicators that allow drivers to identify them. As this index, diamond marks painted on the road surface at regular intervals and character markers such as “Carpool Only” are known, and the in-vehicle camera 22 captures these indices while traveling. The traveling lane detector 132 activates the in-vehicle camera 22 while the host vehicle is traveling on a highway equipped with a car pool lane, periodically acquires the imaging data, and analyzes the image. When an index indicating the car pool lane is detected in the analysis image, it is determined that the host vehicle is traveling on the car pool lane.

  If the traveling lane detection unit 132 can determine the traveling lane of the own vehicle based on the traveling information from the GPS satellite or the received signal from the transmitter embedded in the car pool lane, It can also be designed to make a determination.

  The HOV car determination unit 134 determines whether the host vehicle is a HOV car that can use the car pool lane. In this embodiment, this determination can use information input by the driver to the system by operating the input unit 50. That is, when there is passenger number information preset by the driver, the HOV car determination unit 134 determines from this information whether the host vehicle is a HOV car.

  In addition, it is possible to install the in-vehicle camera so that an image of the passenger can be taken, and by analyzing the image to detect the number of passengers, the HOV car determination unit 134 can perform the determination. Good. Moreover, it is good also as determination data used in the HOV car determination part 134 using a seatbelt installation signal by installing a pressure-sensitive sensor in each seat and detecting a passenger.

  The route calculation unit 136 is based on the road information analyzed by the road information acquisition / analysis unit 130, the travel lane of the host vehicle detected by the travel lane detection unit 132, and the availability information of the HOV car determined by the HOV car determination unit 134. Calculate the optimal guidance route. That is, when the vehicle is traveling on a road that does not have a car pool lane, a general guidance route search is performed in the route search program 106 shown in FIG. When the vehicle is traveling in the restricted time zone and the host vehicle is a HOV car, the route calculation unit 136 is activated, and a guidance route search considering the car pool lane is additionally performed. Done.

  First, in a situation where the car pool lane can be used, when the vehicle is traveling in a general lane, the area where entry / exit is allowed to the nearest car pool lane is searched, and this satisfies a predetermined threshold condition Builds the recommended route from this point to the car pool lane. On the other hand, when the host vehicle is already traveling in the car pool lane, the vehicle searches for the entrance / exit permitted area from the car pool lane immediately adjacent to the expressway exit selected by the guide route search in the route search program 106. If the threshold condition is satisfied, the travel route from this point to the general lane is constructed as the recommended route. As a predetermined threshold condition when constructing a recommended route, for example, there is a sufficient separation distance from the vehicle position to the recommended route lane change position, or an appropriate car pool lane before the expressway exit. It is possible to set whether there is an entry / exit permitted area or whether the carpool lane has sufficient travel distance on the recommended route. In addition, conditions based on traffic information such as traffic jam information acquired by the road traffic information presentation program 102 can be added to the threshold condition.

  The display screen configuration unit 138 displays guidance information displayed on the display 92 based on the travel information acquired and calculated by the road information acquisition / analysis unit 130, the travel lane detection unit 132, the HOV car determination unit 134, and the route calculation unit 136. Configure the screen. This guidance information includes map data including traffic information around the vehicle position, and two-dimensional or three-dimensional exit guidance data including a driving situation on a driving path such as an expressway. Details of this will be described later.

  The voice guidance generation unit 140 generates voice information output from the speaker 82 based on the acquired and calculated travel information. Basically, the voice guidance generated here is voice output at a predetermined timing when there is a recommended entry route to the car pool lane and when there is a recommended exit route from the car pool lane. It is something that arouses.

  Next, the travel guidance presentation method in the present embodiment will be described in detail with reference to the flowchart of FIG. The flowchart shown here shows a series of processes from when the guidance display program of the navigation apparatus acquires road information until the travel guidance is displayed on the display 92. This process is accompanied by the traveling of the host vehicle. Are executed periodically and continuously.

  First, corresponding road information is acquired from the road map data 114 according to the vehicle position detected based on the information of the GPS receiver 30 (step S101). The acquired road information is analyzed by the road information acquisition / analysis unit 130, and it is determined whether or not the target road is an expressway having a car pool lane (referred to as a HOV lane in the figure) (step S102). ). Here, when it is determined that the target road is an expressway having a car pool lane, the HOV car determination unit 134 then determines whether the host vehicle is a HOV car (step S103). Next, when it is determined that the host vehicle is a HOV car, the traveling lane detection unit 132 activates the in-vehicle camera 22, acquires an image of the traveling road surface, and the traveling lane of the own vehicle is on the car pool lane. It is detected whether or not there is (step S104).

  On the other hand, if it is determined in step S102 that the target road is a road that does not have a car pool lane, and if it is determined in step S103 that the vehicle is not a HOV car, the process is a normal guidance that does not consider the car pool lane. It is passed to the route display program (steps S108 to S110). That is, it is determined whether the route guidance is set by the driver (step S108), a guidance route is constructed according to the setting (step S109), a display screen on the display 92 is constructed based on this, and voice data Is created (step S110). Here, when the vehicle is on the expressway, the exit guidance of the expressway is displayed in the configuration of the display screen.

  Returning to step S104, when the traveling lane of the host vehicle is detected, it is determined whether route guidance is set by the driver (step S105). If guidance is set, a guidance route is constructed ( Step S106). This guidance route is constructed according to whether or not the vehicle is traveling in the car pool lane, and a specific area of the car pool lane is incorporated as a part of the guidance route as necessary. This specific process will be described later. Next, in step S107, a display screen on the display 92 is constructed and corresponding audio data is generated. This screen configuration includes the guidance route constructed in step S106 when exit road guidance, car pool lane entry / exit area, own vehicle lane position, and route guidance are set. It is. A specific display mode will be described later with reference to the drawings. Through the above processing, a series of processing of the travel guidance presentation program is completed.

  Next, details of the processing in step S106 will be described with reference to the flowchart of FIG.

  If the route guidance is set by the driver in step S105 in FIG. 4, the process moves to step S111 in FIG. 5, where a normal guidance route construction process that does not consider the car pool lane is first performed. . That is, a route guidance search is performed with the highway as a single link group connected by a number of nodes corresponding to the exit position. This search determines one recommended exit from the highway.

  Next, it is determined whether or not the vehicle is traveling on a car pool lane (step S112). If so, the process proceeds to step S116. On the other hand, if the vehicle is not traveling in the car pool lane, that is, is traveling in a general lane, a search is made for the closest entry / exit zone for the car pool lane as an entry point based on the vehicle position (step). S113). When an appropriate entry point is found (step S114), it is determined whether or not it satisfies a predetermined threshold condition (step S115), and if so, the process proceeds to step S116. As the threshold condition here, for example, an allowable shortest distance from the vehicle position to the entry point can be set, and if the distance to the searched entry point is less than this, search for the next entry point is performed. As it does, the process returns to step S113. If it is determined in step S114 that no suitable entry point is finally found, the recommended route using the car pool lane is not constructed, and the recommended route constructed in step S111 is given as an output in this processing. The process ends.

  Next, if the searched entry point satisfies the threshold condition and if it is determined in step S112 that the vehicle is traveling on the car pool lane, it becomes an exit point from the car pool lane. An entry / exit area is searched (step S116). In this case, starting from the exit point from the expressway searched in step S111, the entrance / exit permission area immediately before is searched as the first exit point. If an appropriate exit point is found (step S117), it is determined whether or not it satisfies a predetermined threshold condition (step S118). If so, the process proceeds to step S119. As the threshold condition here, for example, the allowable shortest distance from the exit point of the car pool lane to the exit point of the expressway can be set, and if the distance to the searched exit point is below this, The process returns to step S116 so as to search for the previous exit point. Also, the recommended route should not be established even when the distance from the entry point to the exit point to the searched car pool lane, that is, the mileage of the carpool lane is less than the specified minimum mileage. Can be designed to If it is determined in step S117 that no suitable exit point is finally found, the recommended route using the car pool lane is not constructed, and the recommended route constructed in step S111 is given as an output in this processing. The process ends.

  If it is determined that the exit point from the searched car pool lane satisfies a predetermined threshold condition, the recommended route including this car pool lane is incorporated into the recommended route constructed in step S111 (step S111). S119).

  Next, a specific travel guidance display configuration displayed on the display 92 will be described with reference to FIGS. 6A to 6E.

  FIG. 6A shows a display configuration example of travel guidance during traveling on an expressway. As shown in the figure, the entire display area of the display 92 is divided into two areas by the processing in the display screen configuration unit 138, and the left half is map data for displaying arbitrary wide-area map data including a traveling road. The display area 200, the right half, is configured as an expressway guidance display area 202 that displays two-dimensional expressway travel guidance. In the highway guidance display area 202, different display modes shown in FIGS. 6B to 6E are displayed according to the traveling state of the host vehicle.

  FIG. 6B shows a display mode when the vehicle is traveling on a highway that does not have a car pool lane, or when the vehicle cannot use the car pool lane, that is, a display mode constructed in step S110 of FIG. Yes. In this case, only highway exit guidance (interchange name and distance from the vehicle position to each interchange) existing at a predetermined distance in the forward direction from the vehicle position is shown.

  On the other hand, FIGS. 6C to 6E show the display mode when the host vehicle is traveling on a highway with a car pool lane and the car pool lane can be used, that is, the display mode constructed in step S107 of FIG. Show. In this case, the expressway guidance display area 202 is constructed of two areas, a right area 202a that schematically displays general lane information and a left area 202b that schematically displays car pool lane information. Furthermore, a host vehicle icon 202c indicating which lane the host vehicle is traveling is displayed in the lower area. In the area 202a on the right side, a diagram showing the expressway and its exit guide (interchange name and distance from the vehicle position to each interchange) are shown schematically. The diagram showing the pool lane and the guidance of the access area (distance from the vehicle position to each access area) are shown schematically, and the position of the access area of the car pool lane and the exit position of the expressway The relative position is visually recognized. Therefore, for example, when driving in a car pool lane, it is very easy for the driver to determine which exit area of the car pool lane is effective for exiting from the intended expressway exit. .

  Here, FIG. 6C is a display when the route guidance is not set. FIG. 6D shows a display mode when the route guidance is set and the host vehicle is traveling in a general lane. The recommended route (diagonal lines and arrows) further using the car pool lane is displayed in FIG. 6C. This is a state in which the route indicated by) is added. In this display, it is easy to see that there is an entry / exit permission area for the next car pool lane 1 km beyond the interchange IC-B 4 km ahead, and it is recommended to enter the car pool lane from there.

  On the other hand, FIG. 6E is a display mode when the route guidance is set and the vehicle is traveling on the car pool lane. In this display, it can be seen that it is most efficient to exit from the entry / exit zone of the car pool lane 7 km ahead in order to exit from the interchange IC-C 10 km ahead, and that route is the recommended route (slash and The route indicated by the arrow).

  The preferred embodiment of the present invention has been described in detail above, but the present invention is not limited to the specific embodiment, and various modifications can be made within the scope of the present invention described in the claims. Deformation / change is possible.
