Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the vehicle information processing apparatus 1 according to the present invention, FIG. 2A is a front view showing the operation of the agent 6, and FIG. 2B is a vehicle interior showing an example of an installation location of the agent 6. It is a figure of. The vehicle information processing device 1 of the present embodiment is an agent (hereinafter, simply an agent) that is anthropomorphic to a driver and a passenger (hereinafter, these drivers and the passenger are also referred to as a vehicle occupant or simply an occupant). 6), specifically, the operation / posture of the agent 6, the sound output from the agent 6, the image displayed on the agent 6, and the light emission pattern output from the agent 6. A device that provides information or communicates with an occupant. Here, an example in which the agent 6 is provided in the vehicle is shown, but the present invention is not limited to this. The agent 6 may be an electronic device equipped with an agent function, and may be, for example, a portable speaker-type electronic device or an electronic device with a display. Further, the functions related to the audio output and the video output of the agent 6 described below may be installed in a mobile phone such as a smartphone. Further, the anthropomorphic agent is an example, and may be an agent displaying a predetermined character, avatar, or icon without imitating a human being. The agent may be provided as a physical individual, or the shape of a human being, a character, or the like as an agent may be displayed as an image on a display.

As shown in FIGS. 1, 2A and 2B, the agent 6 is provided with a head 61 that imitates a human face so as to appear and disappear with respect to the base 62 by an actuator (not shown). When the agent 6 outputs the communication information by the agent function receiving the control command from the output unit 11, the head 61 appears from the base 62 as shown in the left figure of FIG. 2A, and the communication information is output. When the output of is finished, the head 61 is immersed in the base 62 as shown in the right figure of FIG. 2A. Raising the head 61 to make it appear from the base 62 is called "appearance", and lowering the head 61 to immerse it in the base 62 is also called "exit".

In the present embodiment, as shown in FIG. 2B, the agent 6 which is a three-dimensional object is installed on the upper surface of the dashboard in the vehicle interior, and the head 61 can rotate around the rotation axis G. As a result, the agent 6 outputs the communication information with the face of the head 61 facing the occupant, or outputs the communication information with the face of the head 61 facing the object to be talked about. This facilitates communication through communication information.

The agent 6 includes a speaker and other sound output units for outputting voice and sound effects, and a display and other display units for displaying images including characters, and the agent 6 includes voice, sound effects, characters, and the like along with the operation of the head 61. Communication information is output by providing the image of. It should be noted that a light emitting body may be provided on the eyes of the face or the like, and communication information may be output according to the light emitting pattern.

In the present embodiment, the agent 6 is configured as a three-dimensional object such as a robot, but the agent of the present invention is not limited to this, and may be a two-dimensional image to be displayed on a display. In addition, although the appearance and exit of the agent 6 was expressed by infesting the head 61 with respect to the base 62, the eyes were opened when the agent appeared, and the eyes were closed when the agent left. Good.

Returning to FIG. 1, the vehicle information processing device 1 of the present embodiment is a vehicle information processing device by executing a ROM in which a program for executing various processes is stored and a program stored in the ROM. It is composed of a computer including a CPU as an operating circuit that functions as 1 and a RAM that functions as an accessible storage device. The vehicle information processing device 1 is used by the output unit 11, the output frequency control unit 12, the detection unit 13, and the like, as shown in FIG. 1, when viewed from the functional configuration exhibited by the execution of the information processing program. It includes a performance detection unit 14, an identification data input unit 15, and a vehicle information acquisition unit 16.

The output unit 11 outputs a control signal to the speaker and other voice output units of the agent 6, a display, a light emitter, and other display units, and outputs communication information by the agent function of the agent 6. The output unit 11 inputs the communication information to be output from the vehicle information acquisition unit 16. For example, regarding the temperature environment inside the vehicle, if the current set temperature of the air conditioner is 25 ° C and the set temperature of the air conditioner that the occupant constantly sets is 20 ° C, "Do you want to lower the set temperature of the air conditioner?" ”Speak to the crew. In this case, the current set temperature of the air conditioner is detected by the set temperature sensor of the air conditioner included in the vehicle sensors 2, and the set temperature of the air conditioner constantly set by the occupant is accumulated in the usage record of the occupant. Extract from the external server 4.

The agent 6 controlled by the output unit 11 outputs communication information using any of voice, image, and light emission pattern as a medium. The communication information includes, for example, (1) information indicating the existence of an agent, (2) information notifying that the agent function is in a predetermined state, or (3) information for notifying information desired by the user. For example, (1) the information indicating the existence of the agent includes an image in which the agent itself is represented, an image in which the agent with a predetermined movement is represented, and the like. For example, (2) the information notifying that the agent function is in a predetermined state is an image, sound, or light emitting pattern indicating that the agent is in a state where it can accept a command or a question from a user. For example, (3) the information for notifying the information desired by the user includes information on POI presumed to be desired by the user, information inquiring whether or not control can be executed on the in-vehicle device presumed to be desired by the user, and the like. Including. Specifically, when the communication information uses voice as a medium, the communication information is audibly output from a speaker or other voice output unit provided in the agent 6, and the communication information uses an image as a medium. The communication information is visually output from a display or other display unit provided on the agent 6, and when the communication information uses a light emitting pattern as a medium, the communication information is provided on the agent 6. Visually output from the eyes and other light emitting parts.

The output frequency control unit 12 controls the output frequency of communication information by the agent function of the agent 6. The output frequency may be the number of times the communication information is output per predetermined time, or may be the number of times the communication information is output per communication unit. For example, when the communication information is information that inquires whether or not control can be executed for an in-vehicle device that is presumed to be desired by the user, and the output frequency is 1, the communication information "Do you want to lower the set temperature of the air conditioner?" Is output only once, and when the output frequency is 3, it means that this communication information "Do you want to lower the set temperature of the air conditioner?" Is output repeatedly three times at intervals. The agent 6 of the present embodiment causes the head 61 to appear from the base 62 when outputting the communication information, and immerses the head 61 in the base 62 when the output of the communication information is completed. Therefore, the output frequency control unit 12 Controls the number of appearances of the head 61 with respect to the base 62.

It is desirable to repeat the output frequency of communication information from the viewpoint of reliably transmitting communication information to the occupants, but depending on the individuality of the occupants, it is rather annoying that the output frequency is high. Sometimes. Therefore, the output frequency control unit 12 of the present embodiment controls the output frequency of communication information by the agent 6 according to a predetermined state of the occupant detected by the detection unit 13 described later. The details of this control will be described later.

The detection unit 13 detects a predetermined state of the occupant after one communication information is output by the agent function of the agent 6, and outputs this to the output frequency control unit 12. For example, when the communication information is based on a visual image displayed on a display unit such as a display, the detection unit 13 detects a state in which the occupant's line of sight is directed to the display unit on which the communication information is displayed. Specifically, the detection unit 13 detects the time until the occupant's line of sight is directed to the display unit on which the communication information is displayed. Alternatively or in addition to this, the detection unit 13 detects the number of times the line of sight is directed to the display unit on which the communication information is displayed.

For example, when the head 61 of the agent 6 appears from the base 62 and displays communication information such as "Do you want to lower the set temperature of the air conditioner?" On a display (not shown), the in-vehicle camera included in the vehicle sensors 2 is used. The line of sight of the occupant is monitored, and the time from the appearance of the head 61 of the agent 6 from the base 62 to the line of sight of the occupant toward the display is measured. Alternatively, similarly, the line of sight of the occupant is monitored by the in-vehicle camera included in the vehicle sensors 2, and the number of times the line of sight of the occupant is directed to the display after the head 61 of the agent 6 appears from the base 62, that is, a glance. Measure the number of times you have seen it.

The fact that the time from when the head 61 of the agent 6 appears from the base 62 until the line of sight of the occupant heads toward the display is short, it can be judged that the occupant is strongly aware of the agent 6, and conversely, the agent 6 It can be determined that the occupant is not very conscious of the agent 6 because it takes a long time for the occupant's line of sight to go to the display after the head 61 of the occupant appears from the base 62. Similarly, the fact that the number of times the occupant's line of sight is directed to the display after the head 61 of the agent 6 appears from the base 62 means that the occupant is strongly aware of the agent 6, and vice versa. It can be determined that the occupant is not very conscious of the agent 6 because the number of times the occupant's line of sight is directed to the display after the head 61 of the agent 6 appears from the base 62 is small.

If it can be determined that the occupant is not very aware of the agent 6, it is necessary to make the occupant aware of the existence of the agent 6. In such a situation, even if the output frequency is increased, it is more likely that the occupants will be grateful for the awareness rather than the feeling of being persistent or annoying. On the contrary, if it can be determined that the occupant is strongly aware of the agent 6, it is presumed that the occupant is sufficiently aware of the communication information. It is likely that you will feel persistent, annoying, and annoying.

Therefore, in the output frequency control unit 12, the time from the appearance of the head 61 of the agent 6 from the base 62 to the line of sight of the occupant toward the display is short, or the head 61 of the agent 6 appears from the base 62. After that, if it can be determined that the occupant is strongly aware of the agent 6 because the occupant's line of sight is directed to the display many times, the output frequency up to that point is controlled to be relatively small. On the contrary, it takes a long time from the appearance of the head 61 of the agent 6 from the base 62 to the line of sight of the occupant toward the display, or the line of sight of the occupant after the head 61 of the agent 6 appears from the base 62. If it can be determined that the occupant is not very aware of the agent 6 because the number of times the occupant is directed to the display is small, the output frequency up to that point is controlled relatively large.

When the head 61 of the agent 6 appears from the base 62 and the communication information is based on an auditory voice emitted from a voice output unit such as a speaker, the detection unit 13 inputs a voice command by the occupant and outputs the communication information. Detects whether or not it was performed within a predetermined time after it was done. For example, when the communication information "Do you want to lower the set temperature of the air conditioner?" Is output, the occupant inputs a voice command such as "Yes, please lower" within a predetermined time (for example, 10 seconds) from this output. In that case, it can be determined that the occupant is strongly aware of the agent 6. On the other hand, if the occupant inputs a voice command such as "Yes, please lower" after the specified time (10 seconds) has passed, the occupant agrees to lower the set temperature of the air conditioner. However, it can be determined that the agent 6 was not so conscious.

Therefore, in the output frequency control unit 12, the occupant inputs a voice command within a predetermined time after the head 61 of the agent 6 appears from the base 62 and the communication information by voice is output. When it can be determined that the occupant is strongly aware of the agent 6, the output frequency up to that point is controlled to be relatively small. On the contrary, the occupant is the agent 6 as in the case where the occupant inputs a voice command after a predetermined time has elapsed after the head 61 of the agent 6 appears from the base 62 and the communication information by voice is output. When it can be judged that the output frequency is not so conscious, the output frequency up to that point is controlled relatively large.

The usage record detection unit 14 detects the record of the occupant using the vehicle information processing device 1. What is detected by the usage record detection unit 14 is not particularly limited, but the occupant is specified based on the identification data input to the identification data input unit 15, and the occupant uses the vehicle information processing device 1. Calculate the actual usage value according to the time and / or frequency. The usage record value calculated by the usage record detection unit 14 is output to the output frequency control unit 12, and the output frequency of communication information is controlled according to the magnitude of the usage record value. Specifically, when the actual usage value of the occupant is small, the characteristics of the occupant cannot be sufficiently grasped as compared with the case where the actual usage value is large, so that the output frequency of the communication information is largely controlled. The details will be described later. The usage record detection unit 14 may be omitted if necessary.

The identification data input unit 15 is an interface for inputting identification data for identifying the occupant of the vehicle to which the vehicle information processing device 1 of this example is applied. Then, when the occupant carries a terminal device (portable computer such as a smartphone) that stores his / her identification data and gets on the vehicle, the occupant's identification data is transmitted to a short-range radio such as Bluetooth (registered trademark). The occupant's identification data can be automatically or semi-automatically read via the communication network, or manually input by the occupant using the input button (not shown) set as the identification data input unit 15. Entered. Further, the wireless key of the vehicle stores the identification data of the occupant, and when the vehicle is unlocked or started by using the wireless key, the identification data of the occupant is transmitted to the identification data input unit 15 for short-distance wireless communication. It may be read automatically or semi-automatically via a net.

The vehicle sensors 2 include various sensors for in-vehicle electrical components such as the above-mentioned air conditioner, an indoor camera that images the interior of the vehicle, an in-vehicle image pickup device that images the surroundings of the vehicle, and a radar device that detects obstacles in the vicinity of the vehicle. , Own vehicle position detection device including GPS receiver, steering angle sensor for detecting the steering angle of the vehicle, acceleration / deceleration sensor for detecting acceleration / deceleration of the vehicle, and the like. The detection signal detected by the vehicle sensors 2 is output to the vehicle information acquisition unit 16.

The map database 3 is a memory that stores, for example, three-dimensional high-precision map information including location information of various facilities and specific points, and is accessible from the vehicle information acquisition unit 16. The three-dimensional high-precision map information stored in the map database 3 is three-dimensional map information based on the road shape detected when driving on an actual road using a data acquisition vehicle, and is a curved road together with the map information. And detailed and highly accurate position information such as the size of the curve (for example, curvature or radius of curvature), road confluence, branch point, tollgate, lane reduction position, service area / parking area, etc. are three-dimensional information. The map information associated with.

The vehicle information acquisition unit 16 acquires communication information to be output to the occupant by using the function of the agent 6. The vehicle information acquisition unit 16 collects various information from the vehicle sensors 2 and the map database 3, the external WEB site, and other external servers 4 via the telecommunication network 5 such as the Internet, and communicate information. To serve.

Next, the information processing procedure of the vehicle information processing device 1 of the present embodiment will be described. 3A to 3C are flowcharts showing an information processing procedure executed by the vehicle information processing device 1 of FIG. First, when the occupant gets on the vehicle, the identification data of the occupant is input to the identification data input unit 15 in step S1 of FIG. 3A. The occupant identification data input to the identification data input unit 15 is output to the output frequency control unit 12 and the output unit 11. Along with this identification data, the usage record value of the occupant is acquired from the usage record detection unit 14, and this is output to the output frequency control unit 12.

In step S2, the line of sight of the occupant is monitored by using the indoor camera included in the vehicle sensors 2. In step S3, the head 61 of the agent 6 appears from the base 62 by the control signal of the output unit 11, and the agent 6 appears. In step S4, the output unit 11 displays the communication information provided by the vehicle information acquisition unit 16 on the display of the agent 6.

In step S5 of FIG. 3B, the output frequency control unit 12 reads the movement of the line of sight of the occupant monitored in step S2, the agent 6 appears in step S3, and the communication information is displayed on the display in step S4. The time from when the occupant's line of sight is directed toward the display is measured. Then, when the measured time is within a preset predetermined time (for example, within 3 seconds), the output frequency control unit 12 determines that the occupant is strongly aware of the agent 6, and steps S6. Proceed to. On the contrary, in step S5, when the time from when the communication information is displayed on the display until the line of sight of the occupant heads toward the display exceeds a preset predetermined time (for example, 3 seconds), the output frequency control The unit 12 determines that the occupant is not very aware of the agent 6, and proceeds to step S7.

In step S6, since the occupant is strongly aware of the agent 6, the output frequency control unit 12 increases the count of the state in which the agent is recognized. Specifically, the output frequency control unit 12 makes the output frequency value relatively smaller than the previous values. Further, in step S7, since the occupant is not so conscious of the agent 6, the output frequency control unit 12 increases the count in the state where the agent is not recognized. Specifically, the output frequency control unit 12 increases the output frequency value relative to the previous values.

In step S8, the output frequency control unit 12 calculates the probability of the state of recognizing the agent. The probability of the state of recognizing the agent is, for example, the total A + B of the count A of the state of recognizing the agent, the count A of the state of recognizing the agent, and the count B of the state of not recognizing the agent. It is defined as the rate divided by (A / (A + B)).

For example, if the initial value of the count A in the state of recognizing the agent is 50 and the initial value of the count B in the state of not recognizing the agent is 50, the probability X of the state of recognizing the agent in the initial value is , X = 50 / (50 + 50) = 0.5. Then, when the reaction of the occupant to the output of the next communication information is in the state of recognizing the agent, assuming that the initial value 50 is counted up by 1 point, the state of recognizing the agent at that time. The probability X1 of is X1 = 51 / (51 + 50) = 0.505.

In step S9, the output frequency control unit 12 determines whether or not the probability of the state of recognizing the calculated agent is equal to or greater than a preset predetermined value, and if it is equal to or greater than the predetermined value, the process proceeds to step S10. If the value is less than the predetermined value, the process proceeds to step S11. Then, in step S10, the output frequency control unit 12 makes the output frequency of the communication information relatively smaller than the previous values. Further, in step S11, the output frequency control unit 12 increases the output frequency of the communication information relatively higher than the values up to that point.

In step S12 of FIG. 3C, the output frequency control unit 12 determines whether or not the usage record value of the occupant detected by the usage record detection unit 14 is equal to or higher than a preset predetermined value, and is equal to or higher than the predetermined value. If it is, the process proceeds to step S13, and if it is less than the predetermined value, the process proceeds to step S14. Then, in step S13, the output frequency control unit 12 makes the output frequency of the communication information relatively smaller than the previous values. Further, in step S14, the output frequency control unit 12 increases the output frequency of the communication information relatively higher than the values up to that point.

In step S15, the output unit 11 immerses the head 61 of the agent 6 in the base 62 and leaves the base 62. In step S16, it is determined whether or not the setting of communication using the agent 6 has been turned off, and if it continues to be turned on, the process returns to step S2 in FIG. 3A, and if it is turned off, this routine is performed. To finish.

Next, another example of the information processing procedure of the vehicle information processing device 1 of the present embodiment will be described. 4A to 4C are flowcharts showing an information processing procedure executed by the vehicle information processing device 1 of FIG. This example describes a specific example of outputting communication information regarding a proposal for changing the set temperature of an air conditioner. First, when the occupant gets on the vehicle, the identification data of the occupant is input to the identification data input unit 15 in step S21 of FIG. 4A. The occupant identification data input to the identification data input unit 15 is output to the output frequency control unit 12 and the output unit 11. Along with this identification data, the vehicle information acquisition unit 16 acquires the history information of the set temperature of the air conditioner when the occupant previously got on the vehicle from the external server 4 and outputs this to the output frequency control unit 12.

In step S22, the current set temperature of the air conditioner is detected from the set temperature sensor of the air conditioner included in the vehicle sensors 2. In step S23, the output frequency control unit 12 compares the current set temperature with the unique set temperature constantly set by the occupant, and if there is a difference of a predetermined value or more set in advance, step S24. If there is no difference greater than or equal to the specified value, the routine ends. In step S24, the output frequency control unit 12 determines whether or not the occupant has changed the set temperature of the air conditioner within a predetermined time, proceeds to step S25 if the temperature is changed, and if not, this routine. To finish.

In step S25, the utterance of the occupant is monitored by using the microphone and the voice recognition device included in the vehicle sensors 2. In step S26 of FIG. 4B, the head 61 of the agent 6 appears from the base 62 and the agent 6 appears by the control signal of the output unit 11. In step S27, the output unit 11 outputs communication information regarding the set temperature of the air conditioner provided by the vehicle information acquisition unit 16, for example, a voice such as "Do you want to lower the set temperature of the air conditioner?" From the speaker of the agent 6. ..

In step S28, the output frequency control unit 12 analyzes the utterance of the occupant monitored in step S25, and determines whether or not the occupant's consent command such as "Yes, please lower" is input. At the same time, when the occupant's consent command is input, the time from when the communication information "Do you want to lower the set temperature of the air conditioner?" Is output from the speaker until the consent command is input is measured. Then, in step S28, the output frequency control unit 12 determines whether or not the occupant's consent command has been input within a predetermined time set in advance, and if it is input, proceeds to step S29, and if it is not input, proceeds to step S29. The process proceeds to step S32.

In step S29, the output frequency control unit 12 sets to lower the set temperature of the air conditioner, and in step S30, the output frequency of the communication information is relatively reduced. In step S31, the output unit 11 leaves the agent 6. In step S32, the output frequency control unit 12 determines whether or not the occupant's consent command has been input after the preset predetermined time has been exceeded, and if it is input, proceeds to step S33, and if it is not input. Ends this routine. In step S33, the output frequency control unit 12 relatively increases the output frequency of the communication information.

In step S34, it is determined whether or not the setting of communication using the agent 6 is turned off, and if it continues to be turned on, the process returns to step S22 in FIG. 4A, and if it is turned off, this routine is performed. To finish.

As described above, according to the vehicle information processing device 1 and the method of the present embodiment, the frequency of output of communication information by the agent 6 is controlled according to a predetermined state of the occupant detected by the detection unit 13. As a result of the output frequency that balances persistence and politeness, it becomes easier for the occupants to have a good impression and familiarity with the agent.

Further, according to the vehicle information processing device 1 and the method of the present embodiment, when the communication information by the agent 6 is visually output from the display unit, the detection unit 13 directs the line of sight of the occupant to the display unit. Since the detected state is detected, it becomes easy to detect a predetermined state of the occupant.

Further, according to the vehicle information processing device 1 and the method of the present embodiment, the detection unit 13 detects the time until the occupant's line of sight is directed to the display unit and / or the number of times the line of sight is directed. In addition to facilitating the detection of a predetermined state of the occupant, quantitative evaluation becomes possible.

Further, according to the vehicle information processing device 1 and the method of the present embodiment, when the time until the occupant's line of sight is directed to the display unit is short, the occupant's line of sight is directed to the display unit. When the output frequency is controlled to be smaller than when the time is long, when the number of times the occupant's line of sight is directed to the display unit is large, and when the number of times the occupant's line of sight is directed to the display unit is small. In comparison, the output frequency is controlled to be small. As a result, the output frequency can be set according to the degree of recognition of the occupant's agent.

Further, according to the vehicle information processing device 1 and the method of the present embodiment, the detection unit 13 detects whether or not the input of the voice command by the occupant is performed within the predetermined time, so that the predetermined state of the occupant is determined. It becomes easier to detect.

Further, according to the vehicle information processing device 1 and the method of the present embodiment, when the occupant inputs the voice command within the predetermined time, the occupant inputs the voice command beyond the predetermined time. The output frequency is controlled to be smaller than in the case. As a result, the output frequency can be set according to the degree of recognition of the occupant's agent.

Further, according to the vehicle information processing device 1 and the method of the present embodiment, the usage record detection unit 14 for detecting the record of the occupant using the vehicle information processing device is further provided, and the usage record value of the occupant is increased. Since the output frequency of the communication information by the agent 6 is controlled, the output frequency is further balanced between persistence and politeness.

Further, according to the vehicle information processing device 1 and the method of the present embodiment, when the actual usage value of the occupant is small, the output frequency is controlled to be larger than when the actual usage value is large. The output frequency can be set according to the degree of recognition.
