JP-A-2002-202147

A general navigation device displays a map around the vehicle and a guidance route in detail on the display unit to guide the route to the destination. On the other hand, there is known a navigation device (hereinafter, referred to as "voice navigation device") that guides a route to a destination exclusively by voice output without displaying a map or a guidance route. In the case of the voice navigation device, since the content of the voice guidance is different from that of the general navigation device, the method of continuous guidance is also different from that of the general navigation device.

In one example, it is determined that it is necessary to provide guidance when the voice navigation device should be careful about the movement of the lane, even if the guidance is not provided because the general navigation device only goes straight. In some cases. At that time, if the continuous guidance is performed under the same conditions as a general navigation device, it is conceivable that the timing of telling the driver how to turn the straight ahead will be too late.

The present invention has been made to solve the above problems, and mainly provides an information processing apparatus capable of appropriately performing continuous guidance when route guidance is mainly performed by voice. Purpose.

The invention according to claim is an information processing device that provides information on the movement of a vehicle, and guides a straight-ahead lane to be traveled at a lane guide that guides a straight-ahead lane to be traveled based on a route. A voice guidance unit for guiding a course change at the change guidance site is provided, and the voice guidance unit is a lane guidance site and the course change guidance site when the lane guidance site and the course change guidance site are continuous. Depending on the order and the distance, it is determined whether to guide the lane guide point and the course change guide point individually or continuously at one time.

Further, the invention described in the claims is an information output method executed by an information processing device that provides information on the movement of a vehicle, and travels at a lane guidance site that guides a straight-ahead lane to be traveled based on a route. The lane is provided with a voice guidance process for guiding a straight lane to be to be made and guiding a course change at a course change guidance place, and the voice guidance process is performed when the lane guidance place and the course change guidance place are continuous. Depending on the order and distance between the guide point and the course change guide point, it is determined whether to guide the lane guide point and the course change guide point individually or continuously at one time.

Further, the invention according to the claim is a program executed by an information processing device including a computer and providing information on the movement of a vehicle, and is a lane guide point that guides a straight lane to be traveled based on a route. The computer is made to function as a voice guidance unit that guides the straight lane to be traveled in the vehicle and guides the course change at the course change guidance area. In this case, it is determined whether to guide the lane guide point and the course change guide point individually or continuously at one time according to the order and distance between the lane guide point and the course change guide point. ..

A configuration example of the voice guidance system according to the first embodiment is shown. An example of the schematic configuration of the voice guidance device is shown. An example of a course change guide and a lane guide is shown. The criteria for determining whether or not to perform continuous guidance are shown. An example of a guide route is shown. Another example of the guidance route is shown. It is a flowchart of a route guidance process. This is a configuration example of the voice guidance system according to the second embodiment. An example of the schematic configuration of the server device is shown.

In one preferred embodiment of the present invention, it is an information processing device that provides information on the movement of a vehicle, and guides a straight-ahead lane to be traveled at a lane guide that guides a straight-ahead lane to be traveled based on a route. However, the voice guidance unit is provided with a voice guidance unit for guiding the course change at the course change guidance site, and the voice guidance unit is provided with the lane guidance site and the course change when the lane guidance site and the course change guidance site are continuous. Depending on the order and distance of the guide points, it is determined whether to guide the lane guide points and the course change guide points individually or continuously at one time.

The above information processing device is provided with a voice guidance unit that guides the straight lane to be traveled at the lane guide that guides the straight lane to be traveled based on the route, and guides the route change at the route change guide. When the lane guide point and the course change guide point are continuous, the voice guidance unit individually guides the lane guide point and the course change guide point according to the order and distance of the lane guide point and the course change guide point. Decide whether to guide at once or continuously. As a result, continuous guidance is appropriately performed according to the order and distance between the lane guidance site and the course change guidance site.

In one aspect of the information processing device, when the lane guide point exists next to the course change guide point, the voice guidance unit has a first distance between the course change guide point and the lane guide point. When the distance is less than or equal to the distance, the course change guide point and the lane guide point are continuously guided at one time, and when the course change guide point exists next to the lane guide point, the lane guide point and the course guide point are present. When the distance to the change guide point is equal to or less than the second distance longer than the first distance, the course change guide point and the lane guide point are continuously guided at one time.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
<First Example>
[System configuration]
FIG. 1 shows a configuration example of a voice guidance system according to a first embodiment of the information processing apparatus of the present invention. The voice guidance system includes a vehicle Ve and a voice guidance device 1.

The voice guidance device 1 moves together with the vehicle Ve and provides route guidance mainly by voice so that the vehicle Ve travels along a route to be guided (also referred to as a "guidance route"). Note that "route guidance mainly by voice" refers to route guidance in which the user can grasp at least the information necessary for driving the vehicle Ve along the guidance route only by voice, and the voice guidance device 1 is at the current position. It does not exclude the auxiliary display of surrounding maps. In this embodiment, the voice guidance device 1 outputs at least information about a point on the route (also referred to as a “guidance point”) in which guidance is required by voice. Here, the guide point corresponds to, for example, an intersection accompanied by a right or left turn of the vehicle Ve, or another passing point that is important for the vehicle Ve to travel along the guide route. The voice guidance device 1 provides voice guidance regarding a guidance point such as the distance from the vehicle Ve to the next guidance point and the traveling direction at the guidance point. Hereinafter, the voice related to the guidance for the guidance route is also referred to as "route voice guidance".

The voice guidance device 1 may be an in-vehicle device installed or attached to the vehicle Ve, or may be a mobile terminal that is brought into a vehicle such as a smartphone and used. In yet another example, the voice guidance device 1 may be incorporated in the vehicle Ve. The voice guidance device 1 is an example of an “information processing device”.

[Device configuration]
FIG. 2 shows an example of a schematic configuration of the voice guidance device 1. The voice guidance device 1 mainly includes a communication unit 11, a storage unit 12, an input unit 13, a control unit 14, a sensor group 15, a display unit 16, and a voice output unit 17. Each element in the voice guidance device 1 is connected to each other via a bus line 10.

The communication unit 11 performs data communication with another terminal based on the control of the control unit 14. The communication unit 11 may receive, for example, map data for updating the map DB (DataBase) 4, which will be described later, from a map management server (not shown).

The storage unit 12 is composed of various types of memory such as a RAM (Random Access Memory), a ROM (Read Only Memory), and a non-volatile memory (including a hard disk drive, a flash memory, etc.). The storage unit 12 stores a program for the voice guidance device 1 to execute a predetermined process. The above-mentioned program may include an application program for performing route guidance by voice, an application program for playing music, an application program for outputting contents other than music (television, etc.), and the like. Further, the storage unit 12 is used as a working memory of the control unit 14. The program executed by the voice guidance device 1 may be stored in a storage medium other than the storage unit 12.

Further, the storage unit 12 stores the map DB (DataBase) 4. Various data necessary for route guidance are recorded in the map DB4. The map DB4 is, for example, a database including road data representing a road network by a combination of nodes and links, facility data indicating a destination, a stop-by place, or a facility that is a candidate for a landmark. The map DB 4 may be updated based on the map information received from the map management server by the communication unit 11 under the control of the control unit 14.

The input unit 13 is a button, a touch panel, a remote controller, a voice input device, etc. for the user to operate. The display unit 16 is a display or the like that displays under the control of the control unit 14. The audio output unit 17 is a speaker or the like that outputs sound based on the control of the control unit 14.

The sensor group 15 includes an outside world sensor 18 and an inside world sensor 19. The external world sensor 18 is one or more sensors for recognizing the surrounding environment of the vehicle Ve, such as a camera, a rider, a radar, an ultrasonic sensor, an infrared sensor, and a sonar. The internal sensor 19 is a sensor that performs positioning of the vehicle Ve, and is, for example, a GNSS (Global Navigation Satellite System) receiver, a gyro sensor, an IMU (Inertial Measurement Unit), a vehicle speed sensor, or a combination thereof. The sensor group 15 may have a sensor that allows the control unit 14 to directly or indirectly (that is, by performing an estimation process) derive the position of the vehicle Ve from the output of the sensor group 15.

The control unit 14 includes a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), and the like, and controls the entire voice guidance device 1. For example, the control unit 14 estimates the position of the vehicle Ve (including the direction in the traveling direction) based on the outputs of one or a plurality of sensors in the sensor group 15. Further, when the destination is specified by the input unit 13, the control unit 14 generates route information indicating a guide route which is a route to the destination, and the position information of the vehicle Ve estimated to be the route information. Route guidance is provided based on the map DB4. In this case, the control unit 14 controls the voice output unit 17 to output the route voice guidance to the voice output unit 17. Further, the control unit 14 controls the display unit 16 to display information on the music being played, video content, a map around the current position, and the like. The control unit 14 and the voice output unit 17 are examples of the voice guidance unit.

Note that the processing executed by the control unit 14 is not limited to being realized by software by a program, and may be realized by any combination of hardware, firmware, and software. Further, the process executed by the control unit 14 may be realized by using a user-programmable integrated circuit such as an FPGA (field-programmable gate array) or a microcomputer. In this case, the integrated circuit may be used to realize a program executed by the control unit 14 in this embodiment. In this way, the control unit 14 may be realized by hardware other than the processor.

The configuration of the voice guidance device 1 shown in FIG. 2 is an example, and various changes may be made to the configuration shown in FIG. For example, instead of storing the map DB 4 in the storage unit 12, the control unit 14 may receive information necessary for route guidance via the communication unit 11 from a map management server (not shown). In another example, the voice guidance device 1 is electrically connected to the voice output unit 17 configured separately from the voice guidance device 1 or by a known communication means, instead of including the voice output unit 17. Then, the audio output unit 17 may be made to output audio. In this case, the audio output unit 17 may be a speaker provided in the vehicle Ve. In yet another example, the voice guidance device 1 does not have to include the display unit 16. In this case, the voice guidance device 1 does not have to control the display at all, and by electrically connecting to the display unit provided on the vehicle Ve or the like by wire or wirelessly, a predetermined display can be displayed on the display unit. You may let it run. Similarly, instead of providing the sensor group 15, the voice guidance device 1 may acquire information output from the sensor provided in the vehicle Ve from the vehicle Ve based on a communication protocol such as CAN (Control Area Network). ..

[Lane information site]
Next, the lane guidance by the voice guidance device 1 will be described. In a general navigation device, a map and a guidance route are displayed on the display unit, so that voice guidance is basically performed at a point where the vehicle changes course. This voice guidance is called "course change guidance", and points such as intersections that provide course change guidance are called "course change guidance points". FIG. 3A shows an example of a course change guide site. When the vehicle Ve is traveling along the guidance route R and the intersection A should be turned right according to the guidance route, a guidance voice prompting the right turn at the intersection A is output, for example, "Turn right at the intersection A." ..

On the other hand, in the case of the voice guidance device 1, voice guidance is performed to indicate the straight lane in which the vehicle should travel even at a point where the vehicle does not need to change course. This voice guidance is called "lane guidance", and points such as intersections where lane guidance is performed are called "lane guidance points". FIG. 3B shows an example of a lane guide site. If the vehicle Ve is traveling along the guidance route R and should go straight at intersection A, but there is a right turn lane at intersection A, the voice guidance device 1 will say, for example, "Go straight at intersection A. Left lane. Please drive. " The lane guide area is set at an intersection having a right turn dedicated lane and a left turn dedicated lane as in the example of FIG. 3 (B). The lane guide point is also set when instructing the lane to be traveled in preparation for the course change at the next course change guide point. For example, if the guidance route indicates a right turn at the next intersection B after the intersection A, voice guidance is given to drive on the right straight lane with the intersection A as the lane guide so that it is easy to turn right at the next intersection B. conduct. In this way, lane guidance is performed to inform the user of the lane to go straight, although the course is not changed at an intersection or the like. In this way, the voice guidance device 1 provides lane guidance and course change guidance at necessary points according to the guidance route.

[Continuous guidance]
When the distance between two consecutive guide points on the guide route is short, continuous guidance is performed. Here, whether or not to perform continuous guidance is determined based on the distance between two consecutive guide points. Specifically, as shown in FIG. 4A, when there are continuous guide points 1 and guide points 2 on the guide path R, the voice guidance device 1 guides the distance D between the two guide points to a predetermined continuous guide. Compare with the judgment distance Dt. Then, when the distance D between the two guide points is longer than the continuous guidance determination distance Dt, the voice guidance device 1 does not perform continuous guidance and guides the two guide points individually. On the other hand, when the distance D between the two guide points is equal to or less than the continuous guidance determination distance Dt, the voice guidance device 1 provides continuous guidance.

Here, in the voice guidance device 1, since there are a lane guidance place and a course change guidance place as guidance places for performing voice guidance, continuous guidance is provided according to the combination of the two consecutive guide points and their distance D. The determination distance Dt is set. FIG. 4B shows an example of setting the continuous guidance determination distance. Now, as shown in FIG. 4A, it is assumed that there are two continuous guide points, that is, a guide 1 and a guide point 2, on the guide path R. Since each guide point is either a lane guide point or a course change guide point, the combination thereof is classified into four cases as shown in FIG. 4 (B). Each case will be described below.

An example of Case 1 is shown in FIG. 5 (A). In case 1, both the guide point 1 and the guide point 2 are the course change guide points. In this case, as shown in FIG. 4B, the continuous guidance determination distance Dt is set to the first distance (350 m). When the distance D between the guide point 1 and the guide point 2 is longer than 350 m, the voice guidance device 1 individually provides course change guidance at the guide point 1 and the guide point 2. For example, the voice guidance device 1 guides "Turn right at the guide 1" at the guide 1 and "Turn left at the guide 2" at the guide 2. On the other hand, the voice guidance device 1 provides continuous guidance when the distance D between the guidance location 1 and the guidance location 2 is 350 m or less. For example, the voice guidance device 1 guides the guide point 1 as "Turn right at the guide point 1. Turn left at the guide point 2 after that." When continuous guidance is provided at the guidance location 1, the guidance may be omitted at the guidance location 2, or guidance may be provided only for the guidance location 2.

An example of Case 2 is shown in FIG. 5 (B). In case 2, the guide point 1 is a course change guide point, and the guide point 2 is a lane guide point. In this case, as shown in FIG. 4B, the continuous guidance determination distance Dt is set to the first distance (350 m). When the distance D between the guide point 1 and the guide point 2 is longer than 350 m, the voice guidance device 1 provides the course change guidance at the guide point 1 and provides lane guidance at the guide point 2. For example, the voice guidance device 1 guides "Turn right at the guide point 1" at the guide point 1, and guides "Please drive on the left lane at the guide point 2" at the guide point 2. On the other hand, the voice guidance device 1 provides continuous guidance when the distance D between the guidance location 1 and the guidance location 2 is 350 m or less. For example, the voice guidance device 1 guides the guide point 1 by saying, "Turn right at the guide point 1. Please drive on the left lane for the guide point 2 after that."

An example of Case 3 is shown in FIG. 6 (A). In case 3, the guide point 1 is the lane guide point, and the guide point 2 is the course change guide point. In this case, as shown in FIG. 4B, the continuous guidance determination distance Dt is set to a second distance (700 m) longer than the first distance (350 m). This is to convey the guidance information at the guidance location 2 to the user as soon as possible. If the continuous guidance determination distance Dt of the case 3 is set to the first distance as in the other cases, continuous guidance will not be performed unless the distance D between the guide points 1 and the guide points 2 is 350 m or less. However, in case 3, since the guide point 1 is a lane guide point, if continuous guidance is not performed, after the straight-ahead lane to be traveled at the guide point 1 is guided, until the vehicle approaches the guide point 2. , The user does not know why he should drive in that lane and is expected to be anxious. Further, as described above, the lane guidance often guides the straight lane to be traveled in preparation for the course change at the next guide point. Therefore, when the next guide point is the course change guide point, It is considered that it is easier for the user to understand the route to be traveled if the guidance is provided at the same time as a pair. Therefore, when the course change guide point comes after the lane guide point, the continuous guidance determination distance Dt is made longer than in other cases to facilitate continuous guidance.

Specifically, when the distance D between the guide point 1 and the guide point 2 is longer than 700 m, the voice guidance device 1 provides lane guidance at the guide point 1 and course change guidance at the guide point 2. For example, the voice guidance device 1 guides "Please drive in the right lane for the guide 1" at the guide 1, and guides "Turn right at the guide 2" at the guide 2. On the other hand, the voice guidance device 1 provides continuous guidance when the distance D between the guidance location 1 and the guidance location 2 is 700 m or less. For example, the voice guidance device 1 guides the guide point 1 as "Please drive in the right lane for the guide point 1. Turn right at the guide point 2 after that."

An example of Case 4 is shown in FIG. 6 (B). In case 4, the guide points 1 and 2 are both lane guide points. In this case, as shown in FIG. 4B, the continuous guidance determination distance Dt is set to the first distance (350 m). When the distance D between the guide points 1 and the guide points 2 is 350 m or more, the voice guidance device 1 provides lane guidance individually at the guide points 1 and the guide points 2. For example, the voice guidance device 1 guides "Please drive the left lane for the guide 1" at the guide 1 and "Please drive the left lane for the guide 2" at the guide 2. do. On the other hand, the voice guidance device 1 provides continuous guidance when the distance D between the guidance location 1 and the guidance location 2 is 350 m or less. For example, the voice guidance device 1 guides the guidance site 1 as "Please drive on the left lane for the guidance site 1. Please drive on the left lane for the guidance site 2 after that."

[Route guidance processing]
FIG. 7 is a flowchart of the route guidance process including the above continuous guidance. When the destination is set by the user and the route guidance is started, the voice guidance device 1 acquires information on two guide points (first and second guide points) from the current position of the vehicle (step S11). .. Next, the voice guidance device 1 determines whether or not the two guide points are in the order of the lane guide points and the course change guide points, that is, whether or not the above case 3 is applicable (step S12).

When the two guide points are not in the order of the lane guide point and the course change guide point (step S12: No), the voice guidance device 1 determines whether or not to perform continuous guidance using the first distance (300 m). (Step S13). On the other hand, when the two guide points are in the order of the lane guide point and the course change guide point (step S12: Yes), the voice guidance device 1 has a second distance (700 m) longer than the first distance (300 m). Is used to determine whether or not continuous guidance is performed (step S14).

Next, the voice guidance device 1 determines whether or not the guidance timing of the first guidance location has arrived (step S15). When the guidance timing of the first guidance location has not arrived (step S15: No), the voice guidance device 1 waits for the arrival of the guidance timing. On the other hand, when the guidance timing of the first guidance location has arrived (step S15: Yes), the voice guidance device 1 provides voice guidance (step S16). At this time, when it is determined in step S13 or S14 that continuous guidance is performed, the voice guidance device 1 performs guidance at the first guidance site and guidance at the second guidance site as continuous guidance. On the other hand, when it is not determined to perform continuous guidance, the voice guidance device 1 only guides the first guidance location.

Next, the voice guidance device 1 determines whether or not the vehicle has arrived at the destination (step S17). If the vehicle has not arrived at the destination (step S17: No), the process returns to step S11. Here, when only the guidance of the first guidance point is performed in step S16, the voice guidance device 1 performs the next two guidance points (second and third guidance points) for which guidance is not performed in step S11. Get the information of the place). On the other hand, when continuous guidance is performed in step S16, the voice guidance device 1 acquires information on the next two guide points (third and fourth guide points) where guidance is not performed in step S11. .. On the other hand, when the vehicle arrives at the destination (step S17: Yes), the route guidance process ends.

As described above, according to the present embodiment, when two consecutive guide points on the guide path arrive in the order of the lane guide point and the course change guide point, the continuous guide determination distance is higher than in other cases. To lengthen. As a result, at the lane guide point, information about the next course change guide point can be easily output by voice at the same time, and the user can drive while being aware of the next course change guide point.

<Second Example>
FIG. 8 is a configuration example of the voice guidance system according to the second embodiment. The voice guidance system according to the second embodiment mainly includes a vehicle Ve, a voice guidance device 1A, and a server device 2. The same components as those in the first embodiment are designated by the same reference numerals as those in the first embodiment, and the description thereof will be omitted.

The voice guidance device 1A has the same configuration as the voice guidance device 1 described in the first embodiment described above (see FIG. 2). In this modification, since the server device 2 performs the route search process and the route guidance process based on the map DB 4, the voice guidance device 1A does not have to have the map DB 4. Then, when the input unit 13 detects an input for designating a destination or the like by the user, the voice guidance device 1A outputs the position information of the vehicle Ve output by the sensor group 15, information about the designated destination, and the like. The including upload signal "S1" is transmitted to the server device 2. Further, the voice guidance device 1A supplies the upload signal S1 including the position information of the vehicle Ve to the server device 2 when the vehicle Ve is in progress. Further, when the voice guidance device 1A receives the control signal "S2" related to the voice output from the server device 2 while the vehicle Ve is in progress, the voice guidance device 1A outputs the voice by the voice output unit 17 based on the control signal S2. In this case, the voice guidance device 1A outputs the route voice guidance based on the control signal S2.

The server device 2 generates route information indicating a guidance route to be traveled by the vehicle Ve based on the upload signal S1 including the destination and the like received from the voice guidance device 1A. Then, the server device 2 generates a control signal S2 regarding the output of the route voice guidance based on the position information of the vehicle Ve indicated by the upload signal S1 transmitted by the voice guidance device 1A and the route information held by the server device 2. do. The server device 2 determines to perform continuous guidance according to the types of the two consecutive guide points (lane guide point or course change guide point) and their distances. Then, the server device 2 transmits the generated control signal S2 to the voice guidance device 1A.

FIG. 9 shows an example of a schematic configuration of the server device 2. The server device 2 mainly has a communication unit 21, a storage unit 22, and a control unit 24. Each element in the server device 2 is connected to each other via a bus line 20.

The communication unit 21 performs data communication with an external device such as the voice guidance device 1A based on the control of the control unit 24. The storage unit 22 is composed of various types of memory such as a RAM, a ROM, and a non-volatile memory (including a hard disk drive, a flash memory, etc.). The storage unit 22 stores a program for the server device 2 to execute a predetermined process. Further, the storage unit 22 includes the map DB4. The control unit 24 controls the entire server device 2 including the CPU, GPU, and the like. Further, the control unit 24 executes at least a part of the processing of the voice guidance device 1 described in the above-described embodiment by executing the program stored in the storage unit 22. For example, the control unit 24 generates the route information indicating the guidance route and the control signal S2 regarding the output of the route voice guidance based on the upload signal S1 received from the voice guidance device 1A via the communication unit 21. .. Then, the control unit 24 transmits the generated control signal S2 to the voice guidance device 1A by the communication unit 21.

The server device 2 executes the processing of the flowchart shown in FIG. 7 based on the upload signal S1 and the map DB4. In this case, the server device 2 generates route information based on the upload signal S1 including information on the destination and the output of the sensor group 15. Further, the server device 2 generates or acquires the position information of the vehicle Ve based on the upload signal S1 regarding the output of the sensor group 15 transmitted from the voice guidance device 1A. Then, the server device 2 generates a control signal S2 for outputting voice guidance including the case of performing continuous guidance based on the guidance route and the position information of the vehicle Ve, and sends the control signal S2 to the voice guidance device 1A. Send.

In this way, even when the server device 2 substantially controls the voice guidance device 1A regarding the route guidance, in the voice guidance system, the vehicle Ve sets the guidance point according to the route voice guidance as in the embodiment. It is possible to preferably notify the user that the progress has been made. In the second embodiment, the server device 2 is an example of the "information processing device".
