[0027] [1. Structure of the electronic conference support system]

[0028] Reference Figure 1 , the structure of the electronic conference support system 1 of the present disclosure is explained. Figure 1 The electronic conference support system 1 is exemplified as supporting an electronic conference between a driver D of a vehicle 50 and other participants P1 and P2 outside the vehicle 50. The vehicle 50 corresponds to the mobile body of the present disclosure. The participants P1 and P2 correspond to the external participants of the present disclosure.

[0029] The vehicle 50 includes: an ECU (Electronic Control Unit) 51 that controls the operation of the vehicle 50; a communication unit 52 that communicates with the electronic conference support system 1 and the like via the communication network 200; a front camera 53 that captures the front of the vehicle 50; a radar 54 that detects the position of an object that exists in front of the vehicle 50; an in-vehicle camera 55 that captures the driver D; a biosensor (life sensor) 56 that is provided on a driver's seat and the like and detects the biometric information (heart rate, pulse, sweat, etc.) of the driver D; an operating unit sensor 57 that detects the operating state of a driving operating unit (accelerator pedal, brake pedal, steering wheel, etc.); a driving condition sensor 58 that detects the driving condition (speed, acceleration, yaw rate, etc.) of the vehicle 50; a navigation device 59 that provides route guidance based on map information; a display 60 of touch panel specification; and a microphone 61.

[0030] The ECU 51 is composed of a single or multiple ECUs, and the driver D uses the electronic conference application (application program) executed by the ECU 51 to access the electronic conference support system 1 and participate in the electronic conference. In addition, the driver D can also participate in the electronic conference using the electronic conference application installed in the portable terminal 70. The portable terminal 70 is a smart phone, a mobile phone, a tablet terminal, etc. The driver D visually confirms the electronic conference screen displayed on the display 60 while performing a touch operation on the display 60 to communicate with other participants P1 and P2.

[0031] ECU51 has an automatic driving function and a driving assistance function. The automatic driving function performs automatic driving control of the vehicle 50 based on the captured image in front of the vehicle 50 captured by the front camera 53, the position of the object in front of the vehicle 50 detected by the radar 54, etc., and the driving assistance function assists the driving operation of the vehicle 50 performed by the driver D.

[0032] When the driver D participates in the electronic conference, the ECU 51 transmits the movement status information Msi indicating the movement status of the vehicle 50, the driving status information Dsi indicating the driving status of the vehicle 50, and the biological information Bmi of the driver D to the electronic conference support system 1 at a predetermined timing. The movement status information Msi includes the speed, acceleration, yaw rate, etc. of the vehicle 50 detected by the driving status sensor 58, the operating status of the traffic light in front of the vehicle 50 recognized from the image captured by the front camera 53, and the status of the road (general road in the city, mountain road, vehicle-only road, etc.) on which the vehicle 50 is traveling recognized by the navigation device 59.

[0033] The driving condition information Dsi includes the driving condition of the vehicle 50 (manual driving, use of the driving assist function, automatic driving), the operation amount and frequency of the accelerator pedal, brake pedal, steering wheel, etc. detected by the operation unit sensor 57. The biometric information Bmi includes the direction of the driver D's line of sight recognized from the image captured by the in-vehicle camera 55, and the heart rate, pulse, and sweat level of the driver D detected by the biometric sensor 56.

[0034] Participant P1 operates terminal device 101 from house 100 such as his own home and uses the electronic conference application, thereby accessing the electronic conference support system 1 and participating in the electronic conference. Terminal device 101 is a personal computer, a tablet terminal, a smart phone, etc., and has a function of communicating via communication network 200. Participant P1 communicates with driver D and participant P2 while visually checking the electronic conference screen displayed on the display unit of terminal device 101. Similarly, participant P2 operates terminal device 111 from house 110, participates in the electronic conference by accessing the electronic conference support system 1, and communicates with driver D and participant P1.

[0035] The electronic conference support system 1 is a computer system including a processor 10, a memory 20, a communication unit 30, etc. A program 21 for controlling the electronic conference support system 1 and a conference handling difficulty map 22 for determining the conference handling difficulty described later are stored in the memory 20. The program 21 may be read from a recording medium (a magnetic disk, an optical disk, a flash memory, etc.) and stored in the memory 20, or may be downloaded from an external server, etc., via a communication network 200 and stored in the memory 20.

[0036] The processor 10 reads and executes the program 21, thereby functioning as an electronic conference control unit 11, an electronic conference participation recognition unit 12, a movement status information acquisition unit 13, a driving status information acquisition unit 14, a biological information acquisition unit 15, a conference handling difficulty determination unit 16, and a conference handling difficulty information providing unit 17. The processing performed by the electronic conference participation recognition unit 12 is equivalent to the electronic conference participation recognition step in the electronic conference support method of the present disclosure, and the processing performed by the movement status information acquisition unit 13 is equivalent to the movement status information acquisition step in the electronic conference support method of the present disclosure. The processing performed by the conference handling difficulty determination unit 16 is equivalent to the conference handling difficulty determination step in the electronic conference support method of the present disclosure, and the processing performed by the conference handling difficulty information providing unit 17 is equivalent to the conference handling difficulty information providing step in the electronic conference support method of the present disclosure.

[0037] The electronic conference control unit 11 communicates with the vehicle 50 (more specifically, the ECU 51), the terminal device 101, and the terminal device 111 via the communication network 200, thereby providing a service of an electronic conference implemented by the driver D, the participants P1, and the participants P2. The electronic conference participation identification unit 12 identifies that the driver D is participating in the electronic conference based on the control state of the electronic conference by the electronic conference control unit 11.

[0038] The movement status information acquisition unit 13 receives and acquires the movement status information Msi transmitted from the vehicle 50 via the communication unit 30. The driving status information acquisition unit 14 receives and acquires the driving status information Dsi transmitted from the vehicle 50 via the communication unit 30. The biometric information acquisition unit 15 receives and acquires the biometric information Bmi transmitted from the vehicle 50 via the communication unit 30.

[0039] The conference handling difficulty determination unit 16 determines the difficulty of the driver D handling the electronic conference based on the movement status information Msi, the driving status information Dsi and the biological information Bmi. Specifically, the conference handling difficulty determination unit 16 performs the following processing to obtain a conference handling difficulty score Cds indicating the difficulty of the driver D handling the electronic conference.

[0040] (1. Calculation of movement status score)

[0041] The conference handling difficulty determination unit 16 sets the movement condition score Mss corresponding to the movement condition information Msi according to the following rules (1-1) to (1-4). The higher the difficulty for the driver D to handle the electronic conference, the higher the movement condition score Mss is set. (1-1) The higher the driving speed of the vehicle 50, the higher the movement condition score Mss. (1-2) Regarding the operating condition of the traffic light in front of the vehicle 50, the movement condition score Mss is increased when the traffic light is green compared to the case where the traffic light is red. (1-3) Regarding the road on which the vehicle 50 is traveling, the movement condition score Mss is increased when the vehicle 50 is traveling on a mountain road compared to the case where the vehicle is traveling on an urban road. (1-4) When vehicle 50 is traveling at an intersection, traveling on a narrow road, traveling on a road with many blind spots, meeting other vehicles on a narrow road, traveling in the rain (the wiper movement speed is determined by a raindrop sensor), or traveling in poor road conditions (a lot of up and down movement is determined by an acceleration sensor), when there is a lot of noise around vehicle 50, when an emergency vehicle is approaching vehicle 50, when the distance from vehicle 50 to the vehicle in front is less than a specified distance (which can change according to the speed of vehicle 50), or when the position and relative speed of a motorcycle traveling near vehicle 50 relative to vehicle 50 meet specified approach conditions, the movement condition score Mss is increased.

[0042] (2. Calculation of driving condition score)

[0043] The conference handling difficulty judgment unit 16 sets a driving condition score Dss corresponding to the driving condition information Dsi according to the following rules (2-1) to (2-4). The higher the difficulty for the driver D to handle the electronic conference, the higher the driving condition score Dss is set. (2-1) The driving condition score Dss is increased in the order of automatic driving → manual driving (with driving assistance) → manual driving (without driving assistance). (2-2) The greater the operation amount of the operating part (accelerator pedal, brake pedal, steering wheel), the higher the driving condition score Dss. (2-3) The higher the operation frequency of the operating part, the higher the driving condition score Dss. (2-4) The driving condition score Dss is increased when the safety function of the vehicle 50 (emergency braking, lane departure warning, etc.) is in operation and when the driver D uses voice operation (Assistant application is activated).

[0044] (3. Calculation of biological information score)

[0045] The conference handling difficulty determination unit 16 sets the biometric information score Bms corresponding to the biometric information Bmi according to the following rules (3-1) to (3-4). The higher the difficulty of the driver D in handling the electronic conference, the higher the biometric information score Bms is set. (3-1) The more stable the direction of the driver D's line of sight (the more the driver D focuses on a specific object), the higher the biometric information score Bms. (3-2) The higher the heart rate or pulse rate of the driver D, the higher the biometric information score Bms. (3-3) The more the driver D sweats, the higher the biometric information score Bms. (3-4) The stronger the glare of the sun or the headlights of the oncoming vehicle felt by the driver D (determined based on the calculated sun angle or the image of the in-vehicle camera 55 (driver monitoring camera)), the higher the biometric information score Bms. The greater the disturbance (irregular heartbeat) of the electrocardiogram of the driver D, the higher the biometric information score Bms. The higher the degree of excitement of the driver D recognized from the tone of the driver D's voice (emotions such as anxiety are conveyed to the other party), the higher the biological information score Bms is made.

[0046] The meeting handling difficulty determination unit 16 applies the movement condition score Mss, the driving condition score Dss, and the biological information score Bms to the meeting handling difficulty map 22 to calculate the meeting handling difficulty score Cds. Figure 2 As shown in the dialog box B, the meeting handling difficulty map 22 is a three-dimensional map that outputs the meeting handling difficulty score Cds for the input of the movement condition score Mss, the driving condition score Dss, and the biological information score Bms.

[0047] The conference handling difficulty map 22 is obtained by mapping the calculation result of the following formula (1), for example.

[0048] Cds=W1×Mss+W2×Dss+W3×Bms·····(1)

[0049] Among them, Mss: moving condition score, Dss: driving condition score, Bms: biological information score, W1~W3: weighting coefficients.

[0050] W1 to W3 are set through verification experiments and computer simulations.

[0051] [2. Provision of meeting response difficulty information]

[0052] according to Figure 2 The flowchart shown in FIG. 1 illustrates the execution steps of the process of providing conference handling difficulty information executed by the electronic conference supporting system 1. The electronic conference supporting system 1 is used by the driver D to drive the vehicle 50 (in Figure 2 If the target vehicle is displayed in Figure 2The process of the flowchart shown.

[0053] exist Figure 2 In step S1, the electronic conference participation identification unit 12 identifies whether the driver D of the vehicle 50 is participating in the electronic conference based on the execution state of the control of the electronic conference by the electronic conference control unit 11. In the next step S2, the electronic conference participation identification unit 12 advances the processing to step S3 when the driver D is participating in the electronic conference, and advances the processing to step S8 when the driver D is not participating in the electronic conference.

[0054] In step S3, the movement status information acquisition unit 13 receives and acquires the movement status information Msi from the vehicle 50 via the communication network 200. In the next step S4, the driving status information acquisition unit 14 receives and acquires the driving status information Dsi from the vehicle 50 via the communication network 200. In the next step S5, the biometric information acquisition unit 15 receives and acquires the biometric information Bmi from the vehicle 50 via the communication network 200.

[0055] In the next step S6, the meeting handling difficulty determination unit 16 calculates the movement condition score Mss, the driving condition score Dss, and the biological information score Bms as described above based on the movement condition information Msi, the driving condition information Dsi, and the biological information Bmi. Then, the meeting handling difficulty determination unit 16 applies the movement condition score Mss, the driving condition score Dss, and the biological information score Bms to the meeting handling difficulty map 22 to calculate the meeting handling difficulty score Cds.

[0056] In the next step S7 , the conference handling difficulty information providing unit 17 transmits the conference handling difficulty information Cdi including the conference handling difficulty score Cds to the terminal devices 101 and 111 used by the other participants P1 and P2 of the electronic conference.

[0057] Here, Figure 3 The electronic conference screen 300 displayed on the display units of the terminal devices 101 and 111 is shown. The electronic conference screen 300 displays an image 310 of the driver D who is participating in the electronic conference, an image 311 of another participant P1, an image 312 of another participant P2, a conference end button 320 for instructing to exit from the electronic conference, a microphone button 321 for instructing to turn on / off a microphone, and a camera button 322 for instructing to turn on / off a camera.

[0058] When the terminal devices 101 and 111 receive the conference handling difficulty information Cdi transmitted from the electronic conference support system 1, the electronic conference application displays a conference handling difficulty report image 330 near the image 310 of the driver D. The conference handling difficulty report image 330 displays 10-stage indicators 331 corresponding to the conference handling difficulty score Cds. The indicator 331 displays a longer range (the number of displayed blocks increases) as the conference handling difficulty score Cds increases (as the difficulty of the driver D handling the electronic conference increases).

[0059] In addition, Figure 3 , an example is shown in which information on the driving state of "manual driving without driving assistance" which is an element considered in calculating the meeting handling difficulty score Cds is displayed together with the indicator 331 in the meeting handling difficulty report image 330. In addition, the driving speed of the vehicle 50, the operating state of the traffic light in front of the vehicle 50, the operation amount of the accelerator pedal by the driver D, etc. may also be displayed in the meeting handling difficulty report image 330.

[0060] The other participants P1 and P2 can intuitively and quickly recognize the difficulty of the driver D in coping with the electronic conference based on the length of the indicator 331. Then, the other participants P1 and P2 can consider the difficulty of the driver D in coping with the electronic conference and decide the timing of displaying the shared and visually confirmed data on the electronic conference screen 300 and the timing of asking the driver D. In this way, the smooth communication between the other participants P1 and P2 and the driver D can be supported.

[0061] [3. Other embodiments]

[0062] In the above-mentioned embodiment, the driving condition information acquisition unit 14 and the biological information acquisition unit 15 are provided, and the meeting handling difficulty determination unit 16 determines the meeting handling difficulty (the meeting handling difficulty score Cds) based on the movement condition information Msi, the driving condition information Dsi, and the biological information Bmi. As another embodiment, only one of the driving condition information acquisition unit 14 or the biological information acquisition unit 15 may be provided, and the meeting handling difficulty may be determined based on the movement condition information Msi and the driving condition information Dsi, or based on the movement condition information Msi and the biological information Bmi. In addition, the driving condition information acquisition unit 14 and the biological information acquisition unit 15 may be omitted, and the meeting handling difficulty determination unit 16 may determine the meeting handling difficulty based only on the movement condition information Msi.

In this case, the electronic conference support system of the present disclosure is constituted by the electronic conference support system 1 and the ECU 51. In addition, the conference handling difficulty information providing unit 17 may be constituted as a function of the ECU 51. In this case, the electronic conference support system of the present disclosure is constituted only by the ECU 51 of the vehicle 50, and the conference handling difficulty information Cdi is transmitted from the vehicle 50 to the terminal devices 101 and 111.

[0064] In the above-mentioned embodiment, the driver D uses the electronic conference application executed by the ECU 51 to participate in the electronic conference. However, when the driver D uses the electronic conference application executed by the portable terminal 70 to participate in the electronic conference, the electronic conference control unit 11 recognizes the moving speed of the portable terminal 70 based on the position information of the portable terminal 70 transmitted from the portable terminal 70, thereby recognizing that the driver D is participating in the electronic conference. In this case, the movement status information Msi, the driving status information Dsi, and the biological information Bmi may be transmitted from the ECU 51 to the portable terminal 70, and the movement status information Msi, the driving status information Dsi, and the biological information Bmi may be transmitted from the portable terminal 70 to the electronic conference support system 1 via the communication network 200.
