Description

  The present invention relates to a travel guide device and a computer program that provide travel guidance based on a guide route.

  2. Description of the Related Art In recent years, a navigation device is often mounted on a vehicle that provides vehicle travel guidance so that a driver can easily arrive at a desired destination. Here, the navigation device detects the current position of the vehicle by a GPS receiver or the like, acquires map data corresponding to the current position through a recording medium such as a DVD-ROM or HDD or a network, and displays it on a liquid crystal monitor. It is a device that can do. Further, the navigation device has a route search function for searching for an optimum route from the vehicle position to the destination when a desired destination is input, and sets the searched optimum route as a guide route, and displays it. A guide route is displayed on the screen, and when the user approaches an intersection, the user is surely guided to a desired destination by voice guidance. In recent years, some mobile phones, smartphones, tablet terminals, personal computers, and the like have functions similar to those of the navigation device.

  Further, in the above navigation device or the like, when an event that hinders driving of the vehicle such as traffic jam occurs in the guidance route, a route to the destination that avoids the event (so-called detour route) is proposed to the user, The detour route is also set as a new guide route. For example, in Japanese Patent Laid-Open No. 2000-193471, when a user inputs a voice instructing avoidance of an event in a traveling direction (for example, a closed road), a bypass route that avoids the event is searched and guided to the user. The technology to be proposed is proposed.

JP 2000-193471 A (page 6-8)

  However, in the technique of Patent Document 1, the condition for starting the search and guidance for the detour route is that the user has an intention to search and guide the detour route. The intention display was an operation unrelated to the driving operation of the vehicle. Specifically, it is a condition that a voice explaining an event that the user wants to avoid (for example, “Xkm ahead closure”) is output.

  Therefore, in the said patent document 1, there exists a possibility that it may become the burden of a user that a user performs an intention display and may obstruct driving operation of a vehicle. In particular, when there are a plurality of bypass routes and the guide route is changed to any one of the bypass routes, it is necessary for the user to select one of the plurality of bypass routes. In such a case, if a configuration is adopted in which a bypass route selection operation is performed using voice input, button operation, or the like as in Patent Document 1, there is a possibility that a greater burden is placed on the user.

  The present invention has been made in order to solve the above-described conventional problems, and it is possible to search and guide a detour route without increasing the burden on the user and preventing the driving operation of the vehicle. And to provide a computer program.

  In order to achieve the above object, a travel guidance device according to the present invention includes a route setting unit that sets a guide route to a destination, a travel guide unit that provides vehicle travel guidance based on the guide route, and the object A detour route acquisition unit that acquires a detour route that is a route to the ground and is different from the guide route, and a vehicle operation that is advantageous for the vehicle to travel along the detour route with the detour route are proposed. And a guidance route changing unit for setting the detour route as a new guidance route when the vehicle motion proposed by the behavior suggesting unit is performed in the vehicle.

  According to the travel guidance device and the computer program according to the present invention having the above-described configuration, since the bypass route is set to the guide route on the condition of the user's vehicle operation after the bypass route is proposed to the user, the burden on the user is increased. Therefore, it is possible to search and guide a detour route that does not interfere with the driving operation of the vehicle. In particular, even when there are a plurality of bypass routes and the guide route is changed to any one of the bypass routes, any one of the bypass routes can be easily selected from the plurality of bypass routes by the user's vehicle operation. . Furthermore, it is possible to facilitate traveling along a new guide route thereafter by the vehicle operation performed by the user.

It is a flowchart of the detour route guidance processing program which concerns on this embodiment. It is the figure which showed the driving guidance screen displayed on a liquid crystal display. It is the figure which showed an example of the detour circuit. It is the figure which showed the example of guidance of a detour route.

  As described later, the search data 35 includes a route search process for searching for a route from a departure place (for example, the current position of the vehicle) to a set destination, and an event such as a traffic jam when the event occurs. Various data used for the process of searching for a bypass route to be avoided is recorded. Specifically, the cost of quantifying the appropriate degree as a route to an intersection (hereinafter referred to as an intersection cost), the cost of quantifying the appropriate degree as a route to a link constituting a road (hereinafter referred to as a link cost), etc. Cost calculation data used for calculating the search cost is stored.

The link cost is set for each link included in the route for which the search cost is calculated. Based on the link length, the link attribute, road type, road width, number of lanes, traffic conditions, etc. of the link are considered. Is calculated.

  The traffic information DB 32 is a DB that stores traffic information received from an external traffic information center such as a VICS center. In addition to the VICS information, the traffic information may be TPEG (Transport Protocol Expert Group), probe information, or statistical traffic information.

  For example, the traffic information center collects detection results obtained by detecting a vehicle traveling on the road using a sensor installed on the road and information provided from a specific organization (for example, the National Police Agency), and the detection result. It is an information providing center that generates traffic information based on the provided information and provides the generated traffic information to the navigation device 1 by FM multiplex broadcasting, optical beacon, radio beacon or the like. The provided traffic information includes “traffic information for identifying traffic sections and levels of traffic jams”, “traffic regulation information such as road closures, lane regulations, chain regulations”, “failed vehicles, accidents, Information on traffic obstacles such as construction ". For example, when the traffic information center generates traffic information related to traffic jams, the traffic information center obtains the average vehicle speed of the vehicle using a sensor installed on the road, and calculates the traffic jam degree based on the judgment condition defined for each road type. decide. In addition, the traffic information center transmits the latest traffic information to the navigation device 1 every predetermined time (for example, every 5 minutes).

  And navigation ECU13 searches and guides a guidance route or a detour route so that it may mention below based on the traffic information memorized by traffic information DB32.

  On the other hand, the navigation ECU (Electronic Control Unit) 13 is an electronic control unit that controls the entire navigation device 1. The CPU 41 as an arithmetic device and a control device, and a working memory when the CPU 41 performs various arithmetic processes. From the ROM 43 and the ROM 43 in which a detour route guidance processing program (see FIG. 2) to be described later is recorded in addition to the RAM 42 for storing route data when the route is searched, a control program, and the like. An internal storage device such as a flash memory 44 for storing the read program is provided. The navigation ECU 13 has various means as processing algorithms. For example, the route setting means sets a guide route to reach the destination. The travel guidance means provides vehicle travel guidance based on the guidance route. The detour route acquisition means acquires a detour route that is a route that reaches the destination and is different from the guide route. The motion proposing means proposes a vehicle motion that is advantageous for the vehicle in order to travel along the detour route together with the detour route. The guide route changing unit sets the detour route as a new guide route when the vehicle motion proposed by the motion proposing unit is performed in the vehicle.

  The operation unit 14 is operated when inputting a starting point as a travel start point and a destination as a travel end point, and has a plurality of operation switches (not shown) such as various keys and buttons. Then, the navigation ECU 13 performs control to execute various corresponding operations based on switch signals output by pressing the switches. The operation unit 14 may have a touch panel provided on the front surface of the liquid crystal display 15. Moreover, you may have a microphone and a speech recognition apparatus.

  The liquid crystal display 15 includes a map image including a road, traffic information, operation guidance, operation menu, key guidance, guidance route from the departure point to the destination, guidance information along the guidance route, news, weather forecast, Time, mail, TV program, etc. are displayed. In place of the liquid crystal display 15, HUD or HMD may be used.

  The speaker 16 outputs voice guidance for guiding traveling along the guidance route based on an instruction from the navigation ECU 13 and traffic information guidance. Moreover, in this embodiment, when a detour route is searched, it is used also when outputting the vehicle operation | movement advantageous for a vehicle in order to drive | work a detour route.

  The DVD drive 17 is a drive that can read data recorded on a recording medium such as a DVD or a CD. Based on the read data, music and video are reproduced, the map information DB 31 is updated, and the like. A card slot for reading / writing a memory card may be provided instead of the DVD drive 17.

  The communication module 18 is a communication device for receiving traffic information, probe information, and the like transmitted from a traffic information center, for example, a VICS center, a probe center, and the like.

  Next, a detour route guidance processing program executed by the CPU 41 in the navigation device 1 according to the present embodiment having the above configuration will be described with reference to FIG. FIG. 2 is a flowchart of the detour route guidance processing program according to the present embodiment. Here, the detour route guidance processing program is a program that is executed after a guide route is set in the navigation device 1 and guides a detour route that is different from the guide route set when a predetermined condition is satisfied. The program shown in the flowchart of FIG. 2 below is stored in the RAM 42 or ROM 43 provided in the navigation device 1 and is executed by the CPU 41.

  First, in step (hereinafter abbreviated as S) 1 in the detour route guidance processing program, the CPU 41 acquires traffic information transmitted from an external traffic information center such as a VICS center. As described above, the traffic information includes the contents of the traffic event (congestion, traffic stop, lane regulation, chain regulation, broken vehicle, accident, construction, etc.) and information for identifying the section in which the traffic event occurs. The traffic information center transmits the latest traffic information to the navigation device 1 every predetermined time (for example, every 5 minutes). Further, the traffic information acquired in S1 is stored in the traffic information DB 32.

  Next, in S <b> 2, the CPU 41 performs travel guidance based on the currently set guidance route in the navigation device 1. Specifically, a map image of the surrounding area including the guidance route is displayed on the liquid crystal display 15, and a right / left turn instruction or the like for traveling along the guidance route is output. In addition, when traffic information related to traffic events (congestion, traffic closure, lane regulation, chain regulation, broken car, accident, construction, etc.) occurring in the vicinity of the vehicle position or guidance route in S1 is acquired, We will also guide the event. For example, when there is a section where traffic jam occurs, the user is informed that a traffic jam section exists by drawing an arrow colored according to the degree of traffic jam on the road image of the section or outputting sound. Inform.

  Here, FIG. 3 is a diagram showing an example of a travel guidance screen 50 displayed on the liquid crystal display 15 in a state where a guidance route is set in the navigation device 1. The travel guidance screen 50 shows a map image 51 around the current position of the vehicle, a guidance route 52, a destination 53, a vehicle position mark 54 indicating the current position of the vehicle matched on the map, and a traffic jam section. An arrow mark 55 is displayed. Then, by referring to the travel guidance screen 50, the user can grasp the current road shape and traffic conditions around the vehicle, the currently set guidance route, and the like.

  Note that the guidance route to be guided in S2 is a recommended route from the departure point to the destination set by the navigation device 1. When setting a guide route, a known Dijkstra method is used, and a route search is performed using the above-described link cost and intersection cost. The departure point may be the current position of the user or an arbitrary point selected by the user (for example, home). Further, the route search process may be performed not by the navigation device 1 but by an external server, and the search result may be acquired by the navigation device 1 from the external server.

  Next, in S3, based on the traffic information acquired in S1, the CPU 41 determines whether or not an event that prevents the vehicle from traveling has occurred in the guide route from the current position of the vehicle to the destination. Here, events that hinder the traveling of the vehicle include, for example, traffic jams, traffic closures, lane restrictions, chain restrictions, broken cars, accidents, construction, and the like.

  If it is determined that an event that prevents the vehicle from traveling has occurred in the guide route from the current position of the vehicle to the destination (S3: YES), the process proceeds to S4. On the other hand, when it is determined that an event that prevents the vehicle from traveling has not occurred in the guide route from the current position of the vehicle to the destination (S3: NO), the process proceeds to S9.

  In S <b> 4, the CPU 41 acquires a detour route that avoids an event that prevents the vehicle from traveling (hereinafter referred to as a travel inhibition event) that is determined to have occurred in the guidance route.

  Note that the detour route acquired in S4 is a recommended route from the starting point to the destination, which is the current position of the vehicle searched on the condition that the travel inhibition event does not pass. The search for the detour route is performed by a known Dijkstra method using the above-described link cost and intersection cost. For example, if the link cost of a link having a travel inhibition event is infinite, a recommended route can be searched on condition that the travel inhibition event does not pass. Further, it is desirable to acquire not only one detour route but also a plurality of detour routes. The detour route search process may be performed not by the navigation device 1 but by an external server, and the search result may be acquired by the navigation device 1 from the external server.

  For example, when the vehicle travels on the road network shown in FIG. 4 and there is a travel inhibition event on the guide route to the destination, the detour route is a route to the destination that avoids the travel inhibition event. A and detour path B exist. Accordingly, in S4, the detour route A and the detour route B are acquired.

  The subsequent processing of S5 to S8 is performed for each detour route acquired in S4. When there are a plurality of detour routes, the detour routes are performed in order from the detour route with the earlier timing deviating from the current guide route. For example, when there are a detour route A and a detour route B as shown in FIG. 4, first, the processes of S5 to S8 are executed for the detour route A. And after the process of S5-S8 is performed with respect to all the detour routes acquired by said S4, it transfers to S9.

  First, in S5, the CPU 41 proposes a vehicle operation that is advantageous to the vehicle in order to travel along the detour route together with the detour route to be processed. Note that the proposed timing is a predetermined distance before the point where the detour route to be processed deviates from the guide route (for example, 200 m before).

  In addition, the vehicle operation that is advantageous to the vehicle for traveling on the detour route corresponds to the movement to the lane corresponding to the next right / left turn direction of the detour route, or the next right / left turn direction of the detour route in the same lane. The traveling position of the vehicle is moved in the direction to travel. For example, the detour route A shown in FIG. 4 is a route that turns left at the next intersection where the vehicle passes. Accordingly, the vehicle operation that is advantageous to the vehicle for traveling on the detour route A is an operation of moving to the left lane so that it is easy to make a left turn when the vehicle is traveling outside the leftmost lane. . When the vehicle is already traveling in the leftmost lane, the vehicle is decelerated or the traveling position is changed to the left in the same lane. When the detour route is a route that turns right at the intersection, it is an operation of moving to the right lane so as to make a right turn or an operation of changing the travel position to the right in the same lane.

  Accordingly, in S5, the CPU 41 displays the detour route to be processed on the map image and outputs a voice guidance saying “If you wish to detour, please move to the left (right) lane”. . Alternatively, a voice guidance saying “If you want to detour, decelerate and approach the left side (right side)” is output. The vehicle operation may be proposed using the liquid crystal display 15 instead of the voice guidance. Moreover, you may perform about the travel guidance when not detouring (namely, travel guidance in the case of drive | working along a guide route). For example, a voice guidance saying “If you want to detour, move to the left (right) lane. If you do not want to detour, go straight at the intersection.”

  Thereafter, in S <b> 6, the CPU 41 detects the vehicle operation of the vehicle on which the navigation device 1 is mounted by the current position detection unit 11. For example, the vehicle position, vehicle direction, steering angle, and vehicle speed are acquired.

  Next, in S7, the CPU 41 determines whether the vehicle operation proposed in S5 has been performed in the vehicle before the vehicle reaches the determination limit point based on the vehicle operation detected in S6. For example, when an operation of moving to the left lane is proposed, it is determined whether or not the vehicle has moved to the left lane. The determination limit point may be a point where the detour route to be processed deviates from the guide route, or may be a predetermined distance (for example, 50 m before) from the point.

  If it is determined that the vehicle operation proposed in S5 has been performed in the vehicle before the vehicle reaches the determination limit point (S7: YES), the process proceeds to S8. On the other hand, if it is determined that the vehicle operation proposed in S5 has not been performed in the vehicle before the vehicle reaches the determination limit point (S7: NO), after changing the detour route to be processed The processing after S5 is executed again.

  In S <b> 8, the CPU 41 sets the detour route to be processed as a new guide route for the navigation device 1. Thereafter, traveling guidance is performed based on the newly set guidance route. Therefore, until the proposed vehicle operation is performed in the vehicle, the vehicle travel guidance is performed based on the guide route before the change, and after the proposed vehicle operation is performed in the vehicle, the new guide route after the change is performed. Based on (that is, the detour route), the vehicle travel guidance is performed.

  Furthermore, it is desirable to perform travel guidance based on the new guidance route when the guidance route is changed, that is, when the proposed vehicle operation is performed in the vehicle. For example, when the vehicle operation is performed 70 m before the guidance intersection of the new guidance route, a voice guidance “Please turn left 70 m ahead (right turn)” is output. As a result, even when the guide route is changed immediately before the guidance intersection, it is possible to travel more reliably along the new guide route.

  Next, in S9, the CPU 41 determines whether or not the vehicle has reached the destination. And when it determines with the vehicle having reached | attained the destination (S9: YES), the said detour route guidance processing program is complete | finished. On the other hand, when it is determined that the vehicle has not reached the destination (S9: NO), the process returns to S1.

  As a result of executing the detour route guidance processing program, for example, as shown in FIG. 5, when a detour route A and a detour route B exist, a vehicle operation for the detour route A is first proposed. And when a user performs vehicle operation according to the proposal of the vehicle operation | movement of the detour route A, the detour route A becomes a new guidance route. On the other hand, when the user does not follow the proposal of the vehicle operation on the bypass route A, the vehicle operation is proposed on the bypass route B next. And when a user performs vehicle operation according to the proposal of the vehicle operation | movement of the detour route B, the detour route B becomes a new guidance route. On the other hand, when the user does not follow the proposal of the vehicle operation of the detour route B, the current guide route is maintained.

  As described in detail above, in the navigation device 1 and the computer program executed by the navigation device 1 according to the present embodiment, when an event that impedes vehicle travel occurs in the guide route, a detour route that avoids the event (S4), a vehicle operation that is advantageous to the vehicle to travel along the detour route together with the detour route is proposed (S5), and when the proposed vehicle operation is performed in the vehicle, a new detour route is created. Since it is set as a simple guide route (S8), it is possible to search and guide a detour route without increasing the burden on the user and without disturbing the driving operation of the vehicle. In particular, even when there are a plurality of bypass routes and the guide route is changed to any one of the bypass routes, any one of the bypass routes can be easily selected from the plurality of bypass routes by the user's vehicle operation. . Furthermore, it is possible to facilitate traveling along a new guide route thereafter by the vehicle operation performed by the user.

Note that the present invention is not limited to the above-described embodiment, and various improvements and modifications can be made without departing from the scope of the present invention.
For example, in the present embodiment, as a vehicle operation that is advantageous for the vehicle to travel on the detour route, it is proposed to move the lane, decelerate, and approach the right side or the left side in the same lane. Other operations may be proposed as the vehicle operation. For example, the distance between vehicles may be increased.

  Further, in the present embodiment, the detour route and the timing for proposing the vehicle operation that is advantageous to the vehicle for traveling on the detour route are a predetermined distance from the point where the detour route to be processed deviates from the guide route ( For example, before 200 m), it may be the time when a detour route is searched. Further, it may be a point in time when a travel inhibition event occurs in the guide route.

  In the present embodiment, the bypass route is acquired when a travel inhibition event occurs in the guidance route. However, the bypass route may be acquired even when no travel inhibition event occurs in the guidance route. For example, when a travel inhibition event that has occurred in a route other than the guide route is resolved and a route more suitable than the guide route appears, the route may be acquired as a bypass route.

  In addition to the navigation device, the present invention can be applied to a device having a route search function. For example, the present invention can be applied to a mobile phone, a smartphone, a tablet terminal, a personal computer, and the like (hereinafter referred to as a mobile terminal). Further, the present invention can be applied to a system including a server and a mobile terminal. In that case, each step of the above-described detour route guidance processing program (FIG. 2) may be configured to be implemented by either a server or a portable terminal. In addition, when the present invention is applied to a mobile terminal or the like, the present invention can also be applied to travel guidance for a moving body other than a vehicle, for example, a user of a mobile terminal or a two-wheeled vehicle.
