Description

  The present invention relates to an information processing apparatus and an in-vehicle apparatus that provide travel information representing a travel route in an intersection where a vehicle travels.

  Estimate the course of the oncoming vehicle from the attributes such as the shape and structure of the intersection, the presence of facilities near the intersection, etc., so that the right turn at the intersection can be performed safely, and the possibility of contact within the intersection A safe driving support device or the like that can notify the evaluated evaluation result has been proposed (see Patent Document 1). According to the said safe driving assistance apparatus etc., a useful information in order to avoid a contact with the oncoming vehicle in an intersection can be provided to a driver | operator.

JP 2011-215562 A

  By the way, guidance of road lanes at the intersection is performed according to the traveling direction such as straight ahead and right / left turn before the intersection. For example, if the vehicle is on the left side, the driving lane is set to turn right, go straight, turn left, and center right to left in front of the intersection, so vehicles that turn right at the intersection start from the right turn lane closer to the center. Will enter.

  However, there is no setting for the lane in the intersection where the right turn vehicle runs.When the oncoming vehicle also turns to the right, turn right in front of the center position of the intersection, and all oncoming vehicles will be signaled. When the vehicle is stopped, right-turning may be different, such as turning right so as to make a large turn beyond the center of the intersection. In the case of an intersection with many lanes or a complex intersection, etc., the lanes in the intersection are not fixed, which may cause confusion for the driver and may cause vehicle contact, especially when there are multiple right turn lanes. There is also a risk of contact between vehicles running side by side.

  For example, as shown in FIG. 8A, when the vehicle 101 that makes a right turn in the intersection 100a also makes a right turn in the same way for the oncoming vehicle 102, it is necessary to turn forward in the intersection 100a with a small radius to avoid contact. . As shown in FIG. 8B, the vehicle 101 turning right in the intersection 100b bends in the intersection 100 with a large radius because there is no possibility of contact with the oncoming vehicle 102 when the oncoming vehicle 102 is stopped by a signal. Can do. Further, as shown in FIG. 8C, when two lanes 105a and 105b that turn right in the intersection 100c are provided from the center of the road, the vehicles 101a and 101b that turn right are on the road that enters after the right turn to avoid contact. The lanes must travel on lanes 106a and 106b from the center of the road, respectively. In this way, attention is required for traveling within the intersection, but the traveling lane is not clearly shown.

  Embodiments of the present invention will be described with reference to the drawings.

  A providing server that is an in-vehicle device and an information processing device according to an embodiment of the present invention is configured as shown in FIG.

  The in-vehicle device 11 and the providing server 31 constitute a navigation system 10 as shown in FIG. The providing server 31 includes a communication unit 32 that transmits and receives information by communication, a storage unit 33 that stores received information, and a control unit that performs control of the communication unit 32 and the storage unit 33 and information processing based on the received information. 35.

  The communication unit 32 receives the probe information indicating the position information of the traveling vehicle accumulated from an external server (not shown), and at the intersection traveling representing the traveling route traveling in the intersection of the vehicle created by the control unit 35. This is a communication device having a transmission / reception function for transmitting route information to the in-vehicle device 11. The control unit 35 is a processing device including a CPU, a ROM, a RAM, an I / O interface, and a bus connecting them, and is travel information of a vehicle that travels within a predetermined intersection based on probe information received by the communication unit 32. It is an apparatus that acquires intersection travel information and creates intersection travel route information that represents a travel route of a traveling vehicle that enters the intersection. The memory | storage part 33 is a memory | storage device which consists of a hard disk, flash memory, etc. which memorize | stores the said intersection driving | running information and intersection driving | running route information.

  As shown in FIG. 1, the in-vehicle device 11 includes a processing unit 12 including a computer unit (for example, including a CPU, a ROM, a RAM, an I / O interface, and a bus connecting them). The processing unit 12 is connected to a communication unit 13 as a transmission / reception device that receives road traffic information, receives intersection travel route information from the providing server 31, and transmits / receives predetermined communication information. The processing unit 12 is connected to an AV unit 15 capable of reproducing various sound sources and video sources (for example, CD and DVD) and a navigation unit 16 capable of navigating the host vehicle. Further, a speaker 17 is connected to the processing unit 12 via an output circuit 18. As a result, it is possible to output audio signals based on the above intersection travel route information and the like and audio signals related to processing by the AV unit 15 and the navigation unit 16 from the speaker 17 via the output circuit 18. .

  The processing unit 12 includes a storage unit 21 (for example, a semiconductor memory such as a hard disk and a flash memory) that stores various information such as music information and map information used in the AV unit 15 and the navigation unit 16, and an LCD. A display unit 26 that displays video associated with various processes and map information indicating the position of the vehicle in the navigation mode, and an operation unit 27 that can input instructions necessary for various processes formed on the display unit 26 in a touch panel format. And are connected. The intersection travel route information described above may be received from the providing server 31 according to the position of the host vehicle traveling, or stored in advance in a database and stored in the storage unit 21 for traveling. It can also be obtained from the database of the storage unit 21 according to the position of the own vehicle.

  Next, a procedure for creating intersection travel route information by the providing server 31 as an information processing apparatus will be described with reference to FIG. As shown in FIG. 2, the control unit 35 determines predetermined information (whether the intersection is a normal intersection or a compound intersection from the map information stored in the storage unit 33 for an intersection entering from a predetermined direction as a target. Information) is acquired (S11). In the map information, the structure of the intersection is displayed by a link indicating a road and a node where the link intersects. As shown in FIGS. 6A and 6B, the intersection includes, for example, an intersection 43A composed of one node 41a and four links 42a to 42d, and one node 41b and three links 42e to 42g. Like the intersection 43B, a normal intersection composed of one node and three or more links, a plurality of nodes 41c to 41f within a predetermined distance, and a plurality of links 42h to 42q connected thereto The intersection 43C (in addition, the intersection 43D composed of the nodes 41p to 41q and the links 42r to 42w) is divided into compound intersections in which the nodes are close to each other.

  The control unit 35 determines whether or not it is necessary to display the travel route in the intersection for the intersection based on the acquired predetermined information (information regarding the normal intersection or the composite intersection) (S12). Since it is possible to easily visually recognize the traveling of an oncoming vehicle or the like for a normal intersection, the control unit 35 determines that the travel route is not required to be displayed (NO in S12), and determines another intersection. When the intersection is a compound intersection, the control unit 35 determines that it is necessary to display a travel route within the intersection (YES in S12). As mentioned above, since there are multiple nodes at complex intersections and complicated link intersections, a travel route within the intersection is created to prevent contact with other vehicles, and this is provided to in-vehicle devices etc. Is displayed.

  The control unit 35 receives probe information indicating the position information of the traveling vehicle accumulated from an external server (not shown) via the communication unit 32, and travel information of the vehicle traveling within the intersection from the probe information. Is extracted and acquired (S13: intersection information acquisition means).

  The control unit 35 determines whether or not the intersection entering from a predetermined direction can be turned right by using map information or the intersection traveling information (S14). In the case of an intersection that does not allow a right turn, the intersection is either a straight turn or a left turn, and it is less necessary to display the travel route in the intersection. Therefore, the travel route is not created (NO in S14), and the next target The intersection information of the intersection to be obtained is acquired (S11) and determined in the same manner as described above (or the case from another approach route to the intersection may be determined). When the intersection can turn right (YES in S14), the control unit 35 determines from the map information or the intersection traveling information whether there is a single right turn lane at the intersection entering from a predetermined direction (S15). When it is determined that the number of right turn lanes is single (YES in S15), the control unit 35 determines whether or not the oncoming vehicle at the intersection that has entered in the right turn is stopped based on the intersection travel information (S16). It is determined from the intersection travel information (probe information of the vehicle traveling at the intersection) whether there is a right turn of the oncoming vehicle within a predetermined time when the vehicle entering the intersection turns right.

When it is determined that the oncoming vehicle does not stop (NO in S16), the control unit 35 creates the intersection traveling route information shown in FIG. 7A based on the intersection traveling information displayed as an example in FIG. 7B (S17: intersection information creation). means). As shown in FIGS. 7A and 7B, in contrast to a vehicle A52 that enters the intersection 51 and turns right, an oncoming vehicle C53 also enters the intersection and turns right within the same time. The vehicle A52 is located at the coordinate A1 at 12:00:00, then moves to the coordinates A2 to A7 by turning right, reaches the coordinate A8 at 12:00:14, and completes the right turn (12:00 Simultaneous running within the intersection in the range of 00:06 to 12:00:11). Based on the position (coordinates) data of the vehicle A52 that makes a right turn at the intersection 51 and the oncoming vehicle C53 that makes a right turn within the same time, as shown in FIG. 7B, the control unit 35 performs the traveling in the intersection 51 shown in FIG. 7A. Route information representing a route is created, and an average is obtained from a predetermined number of route information, thereby creating intersection travel route information representing a travel route traveling within the difference (S17: intersection travel route information creating means: travel route) Pattern 1). The intersection travel route information is data of position coordinates that travel in the intersection between the vehicle A52 that turns right in the intersection 51 and the oncoming vehicle C53 that turns right in the same time. As will be described later, based on this intersection travel route information, a travel route in the intersection can be created and displayed on a display screen of an in-vehicle device or the like.

  When the oncoming vehicle that makes a right turn within the same time as the vehicle A that makes a right turn at the intersection cannot be extracted from the intersection running information (probe information of the vehicle that runs through the intersection), the control unit 35 It determines with stopping (YES of S16). In this case, the coordinate data of FIGS. 7A and 7B includes only the coordinate data of the vehicle A. Based on the coordinate data of the vehicle A, route information representing the travel route in the intersection 51 is created, and a predetermined number of route information is generated. By calculating the average, the intersection travel route information representing the travel route traveling within the intersection is created (S18: intersection travel route information creating means: travel route pattern 2). As described above, based on this intersection travel route information, a travel route in the intersection can be created and displayed on a display screen of an in-vehicle device or the like.

  When it is determined that the right turn lane is not singular, that is, there are a plurality of right turn lanes (NO in S15), the control unit 35 determines whether or not the oncoming vehicle at the intersection that entered the right turn is stopped based on the intersection travel information ( S19). It is determined from the intersection travel information (probe information of the vehicle traveling at the intersection) whether there is a right turn of the oncoming vehicle within a predetermined time when the vehicle entering the intersection turns right.

When it is determined that the oncoming vehicle stops (YES in S19), the control unit 35 creates the intersection traveling route information shown in FIG. 8A based on the intersection traveling information displayed as an example in FIG. 8B (S20: intersection information creating means). ). As shown in FIGS. 8A and 8B, in contrast to the vehicle A52 that enters the intersection 56 and turns right, the vehicle B55 that runs parallel to the vehicle A enters the intersection and turns right within the same time. The vehicle A52 is located at the coordinate A1 at 12:00:00, then moves to the coordinates A2 to A7 by turning right, reaches the coordinate A8 at 12:00:14, and completes the right turn (12:00 Simultaneous running within the intersection in the range of 00:06 to 12:00:11). The control unit 35 travels within the intersection 51 shown in FIG. 8A based on the position (coordinate) data of the vehicle A52 that turns right at the intersection 56 and the parallel running vehicle B55 that turns right within the same time as shown in FIG. 8B. Is generated, and an average is obtained from a predetermined number of pieces of route information, thereby generating intersection traveling route information representing a traveling route traveling within the difference (S20: intersection traveling route information creating means: traveling) Route pattern 3). The intersection traveling route information is data of position coordinates that travel in the intersection between the vehicle A52 that turns right in the intersection 56 and the parallel vehicle B55 that turns right in the same time. As will be described later, based on this intersection travel route information, a travel route in the intersection can be created and displayed on a display screen of an in-vehicle device or the like.

  When the oncoming vehicle that turns right within the same time as the vehicles A52 and B55 that turn right at the intersection can be extracted from the intersection travel information (probe information of the vehicle that travels at the intersection), the control unit 35 can turn right when the vehicles A52 and B55 turn right. It is determined that the oncoming vehicle is not stopped, that is, the oncoming vehicle also turns right in the intersection 56 at the same time (NO in S19). The control unit 35 creates route information representing the route of travel in the intersection 56 by the vehicles A52 and B55 and the oncoming vehicle that turns right, and obtains an average from a predetermined number of route information to travel within the difference point. Is generated (S21: intersection travel route information creating means: travel route pattern 4). In this case, in addition to the vehicles A55 and B52 shown in FIG. 8A, right turn information (each coordinate position by right turn) in the intersection 56 of the oncoming vehicle is also displayed (not shown). As described above, based on this intersection travel route information, a travel route in the intersection can be created and displayed on a display screen of an in-vehicle device or the like.

  As described above, since there are a plurality of right turn lanes, when a plurality of vehicles turning right are running side by side, the road lane that travels after the right turn is also displayed as a part of the travel route on the screen of the display unit of the in-vehicle device. Is displayed, it is possible to prevent the vehicles from contacting each other not only in the intersection but also after passing the intersection (after the right turn) when running parallel and turning right.

  After creating the intersection travel route information (travel route patterns 1 to 4) described above, the control unit 35 determines whether or not the intersection travel route information has been created (S22), and determines that the creation is to be continued (NO in S22). ) The intersection information is acquired again for the target intersection, and the above-described steps are repeated (S11 to S21). When it is determined that the work is finished (YES in S22), the creation of the intersection travel route information in the present embodiment is finished. As for the target intersection, intersection route information is created for each case where the vehicle enters from each direction, and is stored in a database or the like in association with the target intersection information. In this way, a database storing intersection route information for a plurality of intersections is stored in the providing server 31 that is an information processing apparatus. In addition, about the database which memorize | stored the intersection route information about several intersections, it is also possible to store in the memory | storage part 21 of the vehicle-mounted apparatus 11, or to store in DVD etc. and to mount in the vehicle-mounted apparatus 11. It is. Furthermore, the in-vehicle device 11 can acquire the probe information of the vehicle as an information processing device, create a database storing the intersection route information for a plurality of intersections, and store the database.

  Next, a processing procedure by the processing unit 12 of the in-vehicle device 11 will be described with reference to FIGS. 3A and 3C. If it sets to the navigation mode which input the information regarding the destination to the vehicle-mounted apparatus 11, the processing unit 12 will display the map screen containing the own vehicle on the screen of the display part 22 (S31).

  Next, the processing unit 12 determines whether an intersection approaching within a predetermined distance during traveling of the host vehicle is an intersection that displays a traveling route within the intersection (S32). Whether or not the vehicle is an intersection that displays a travel route can be determined by whether or not the intersection travel route information is provided through communication with the providing server 31. In addition, when the database which memorize | stored the intersection driving | running route information about said intersection used as object is stored in the memory | storage part 21 of the vehicle-mounted apparatus 11, or DVD which memorize | stored the intersection driving | running route information is mounted so that reading is possible. Sometimes, the determination can be made in the in-vehicle device 11.

  When the intersection approaching within a predetermined distance during traveling of the vehicle is not an intersection displaying a travel route (NO in S32), that is, when the intersection is not created with the intersection travel route information, the processing unit 12 It is determined whether or not an intersection approaching within a predetermined distance after passing is an intersection that displays a travel route. On the other hand, when it is determined that the intersection approaching the processing unit 12 is an intersection that displays a travel route (an intersection having intersection travel route information) (YES in S32), the providing server 31 via the communication unit 13 Intersection travel route information is acquired (S33: intersection travel route information acquisition means). Further, the processing unit 12 determines whether or not the own vehicle turns right at the intersection (S34). Since the destination information is input to the in-vehicle device 11 and the guidance route is set, the processing unit 12 can determine the presence or absence of a right turn at the intersection based on the guidance route. When it is determined that the processing unit 12 does not turn right at the intersection (NO in S34), the intersection that approaches within a predetermined distance after passing the intersection is displayed without displaying the traveling route within the intersection. It is determined whether or not. When making a straight or left turn without turning right at the intersection, it is considered that traveling in the intersection is easier than when turning right, so that the travel route is not displayed. However, when it is necessary to display the travel route including the relationship with the oncoming vehicle even when going straight or turning left, it is set so that the intersection travel route information for straight travel or left turn is created in advance and the travel route is displayed. It is also possible to do.

  When the processing unit 12 determines to turn right at the intersection described above by route guidance (YES in S34), it continues to determine whether or not the right turn lane is single (S35). It is determined whether or not to stop (S36). The determination can be made based on intersection travel route information based on vehicle probe information based on actual vehicle travel information.

  When the processing unit 12 has a single right turn lane (YES in S35) and further determines that the oncoming vehicle is stopped (YES in S36), the processing unit 12 creates a traveling route within the intersection based on the acquired intersection traveling route information (S37). : Travel route creation means), and display on the screen of the display unit 22 (S38: display control means: travel route pattern 1 display). As shown in FIG. 4A, the screen of the display unit 22 displays the right turn travel route of the intersection 61A of the host vehicle 62 that turns right at the intersection 61A (travel route pattern 1).

  An intersection 61A shown in FIG. 4A has a structure in which the straight traveling directions 63a and 63b of one intersecting road 63 straddle the other road 65 by a crossover 66, and the vehicle 62 turns right at the intersection 61A from the road 63 to the road 65. Will travel under the overpass 66 to the road 65. At this time, since the oncoming vehicle 67 stops before the intersection 61A, the traveling route 68A created based on the intersection traveling route information based on the vehicle probe information is displayed so as to largely detour inside the intersection 61A. The driver of the host vehicle 62 can travel in the intersection 61A according to the travel route 68A displayed on the display unit 22, although it is difficult to see the oncoming vehicle 67 by the overpass 66 or the like.

  When the processing unit 12 has a single right turn lane (YES in S35) and determines that the oncoming vehicle does not stop (NO in S36), the processing unit 12 creates a travel route in the intersection based on the acquired intersection travel route information (S37). : Travel route creation means), and display on the screen of the display unit 22 (S38: display control means: travel route pattern 2 display). As shown in FIG. 4B, the screen of the display unit 22 displays the right turn travel route of the own vehicle 62 that turns right at the intersection 61B and the intersection 61B of the oncoming vehicle 67 (travel route pattern 2).

  An intersection 61B shown in FIG. 4B has a structure in which the straight traveling directions 63a and 63b of one intersecting road 63 straddle the other road 65 by a crossover 66, and the host vehicle 62 turns right at the intersection 61B from the road 63 to the road 65. Will travel under the overpass 66 to the road 65. At this time, since the oncoming vehicle 67 also makes a right turn at the intersection 61B, each of the traveling routes 68B and 68C created based on the intersection traveling route information based on the vehicle probe information is within the intersection 61B to avoid mutual contact in the intersection 61B. Is displayed to turn the near side with a small radius. The driver of the host vehicle 62 is in a state where it is difficult to see the oncoming vehicle 67 due to the overpass 66 or the like, but since it is displayed that the oncoming vehicle 67 turns right in the intersection 61B at the same time, a display is made so as to avoid the oncoming vehicle 67. According to the travel route 68 displayed on the part 22, the vehicle can travel in the intersection 61B. Even at the intersection 61B where it is difficult to see the oncoming vehicle 67 due to the overpass 66 or the like, the traveling route in which the host vehicle 62 and the oncoming vehicle 67 turn right inside the intersection 61B is displayed on the screen of the display unit 22. It can be predicted that the vehicle will enter the intersection 61B for a right turn.

  When there are not a single right turn lane and there are a plurality of right turn lanes (NO in S35), and when it is determined that the oncoming vehicle is stopped (YES in S41), the processing unit 12 determines the travel route in the intersection based on the acquired intersection travel route information. It is created (S42: travel route creation means) and displayed on the screen of the display unit 22 (S43: display control means: travel route pattern 3 display). On the screen of the display unit 22, as shown in FIG. 5A, the host vehicle 62 that turns right at the intersection 61 </ b> C and the parallel vehicle 71 that runs parallel to the host vehicle 62 and turns right at the intersection 61 </ b> C travel along the intersection 61 </ b> C. Each route is displayed (travel route pattern 3).

  An intersection 61C shown in FIG. 5A has a structure in which the straight traveling directions 63a and 63b of one of the intersecting roads 63 straddle the other road 65 by the overpass 66, and the host vehicle 62 turns right at the intersection 61C from the road 63 to the road 65. And the parallel running vehicle 71 running parallel to this and turning right proceeds under the overpass 66 to the road 65. The own vehicle 62 is near the center of the road 63, and the parallel running vehicle 71 is located on the left side in the traveling direction of the own vehicle 62. Further, since the oncoming vehicles 67a and 67b stop before the intersection 61C, both of the traveling routes 68D and 68E of the own vehicle 62 and the parallel running vehicle 71 created based on the intersection traveling route information based on the vehicle probe information are predetermined. The intersection 61C is displayed to turn right so as to maintain the distance. The travel route 68D of the host vehicle 62 is displayed so as to turn right in a small forward direction in the intersection 61C, and the travel route 68E of the parallel running vehicle 71 is displayed so as to make a right turn largely in the intersection 61C. The travel routes 68D and 68E are based on probe information indicating an actual vehicle travel state, and are displayed as described above in order to make a right turn so as to avoid contact with each other. By traveling in the intersection 61C along the travel paths 68D and 68E, the host vehicle 62 and the parallel running vehicle 71 can avoid mutual contact. Further, since the traveling routes 68D and 68E are displayed up to the approach lanes 65a and 65b to the road 65 that enters after the right turn at the intersection 61C, the host vehicle can be entered by entering the road 65 along the traveling routes 68D and 68E. 62 and the parallel running vehicle 71 can travel safely even after a right turn.

  When the processing unit 12 determines that the right turn lane is not singular and there are multiple lanes (NO in S35), and that the oncoming vehicle is not stopped and can turn right (NO in S41), the processing unit 12 includes the acquired intersection travel route information. A travel route within the intersection is created (S44: travel route creation means) and displayed on the screen of the display unit 22 (S45: display control means: travel route pattern 4 display). On the screen of the display unit 22, as shown in FIG. 5B, the traveling route in the intersection 61C between the own vehicle 62 that turns right at the intersection 61C and the parallel vehicle 71 that runs parallel to the own vehicle 62 and turns right at the intersection 61D. 68F and 68G and traveling routes 68H and 68I of the oncoming vehicles 67a and 67b are displayed (traveling route pattern 4).

  An intersection 61D shown in FIG. 5B has the same structure as the intersection 61C displayed in FIG. 5A, and is different in that the oncoming vehicles 67a and 67b can simultaneously turn right at the intersection 61D. Therefore, as shown in FIG. 5B, the traveling paths 68F, 68G, 68H and 68I based on the probe information are provided with a predetermined distance from each other in order to prevent contact with a vehicle that runs parallel and turns right, In order to prevent contact with the oncoming vehicle, the vehicle turns right so as to make a right turn to the near side in the intersection 61D. Therefore, by making a right turn along the traveling route 68F, the host vehicle 62 can prevent contact with the oncoming vehicles 68H and 68I and also can prevent contact with the parallel running vehicle 71 that turns right. Further, as in FIG. 5A, since the travel routes 68F and 68G are displayed up to the approach lanes 65a and 65b to the road 65 that enters after the right turn, entering the road 65 along the travel routes 68F and 68G The vehicle 62 and the parallel running vehicle 71 can travel safely without touching even after a right turn.

  As mentioned above, when making a right turn at a complex intersection such as a complex intersection, a traveling route that guides traveling within the intersection, a parallel vehicle that turns parallel and turns right, and an oncoming vehicle that enters the intersection when making a right turn Since the driving route is displayed on the screen of the display unit, it is possible to prevent contact with other vehicles by proceeding according to the driving route, and the driving route also shows the road after the right turn, so it is safe even after the right turn You can travel to. Further, in any of the travel route patterns 1 to 4 described above, when the host vehicle 62 travels away from the travel routes 68A, 68B, 68D and 68F displayed, the processing unit 12 gives an alarm from the speaker 17.
