As will be described later, the information presentation control device 100 can acquire the building name and the like existing in the place where the vehicle M is traveling, for example, based on the information on the current position and the map information 11.

The image capturing unit 20 captures various images. The image capturing section 20 is provided in the vehicle M so as to capture an image of the surroundings of the vehicle M, for example. The imaging unit 20 captures, for example, a vehicle running in parallel with the vehicle M, a vehicle approaching the vehicle M from behind, a landscape seen from the vehicle M, and the like as traveling information. The imaging unit 20 outputs the captured video to the travel information acquisition unit 130.

The GPS receiver 30 receives GPS signals. The GPS receiving unit 30 can be realized by a GPS receiving circuit or a GPS receiving antenna. The GPS reception unit 30 outputs the received GPS signal to the travel information acquisition unit 130.

The information presenting section 40 presents various information. The information presenting unit 40 presents the presenting information including the traveling information to the driver of the vehicle under the control of the information presenting control unit 140, for example. Although the details will be described later, the presentation information is information including an instruction to the driver regarding driving for the vehicle. The information presenting unit 40 is not particularly limited, and can be realized by, for example, a display unit that displays a video, a voice output unit that outputs voice, and a light emitting unit that emits light. In other words, in this embodiment, the method of presenting the presentation information is not particularly limited.

The biometric information detection unit 50 detects various biometric information of the driver. The biometric information detection unit 50 detects, for example, the direction of the driver's line of sight or the direction of the face as the biometric information. In this case, the biological information detection unit 50 includes, for example, an infrared camera and an infrared light irradiation unit.

The information presentation control device 100 includes a vehicle information acquisition unit 110, an operation duration measurement unit 120, a travel information acquisition unit 130, an information presentation control unit 140, and a biological information acquisition unit 150. The information presentation control device 100 realizes the function of each unit by expanding and executing the program stored in the storage unit 10. The information presentation control device 100 can be realized by, for example, an electronic circuit including a CPU (Central Processing Unit).

The vehicle information acquisition unit 110 acquires vehicle information regarding the vehicle. The vehicle information acquisition unit 110 acquires, as the vehicle information, for example, operation information regarding the operation of the driving support device mounted on the vehicle. The driving support device is, for example, a control device for automatically driving a vehicle, and refers to an ACC (Adaptive Cruise Control), a LKAS (Lane Keeping Assist System), an automatic braking system, or the like. .. The vehicle information acquisition unit 110 acquires vehicle information including information regarding whether or not each driving support device included in the vehicle is operating. The vehicle information acquisition unit 110 may acquire information on the automatic driving level. The vehicle information acquisition unit 110 acquires from an ECU (Electronic Control Unit) not shown, for example, via a CAN (Controller Area Network). The vehicle information acquisition unit 110 outputs the vehicle information to the information presentation control unit 140.

The operation duration measuring unit 120 measures the operation duration of each driving support device such as ACC and LKAS. The operation duration measuring unit 120 acquires, for example, a start signal and an end signal of the operation of each driving support device from the ECU via the CAN. In this case, the operation duration measuring unit 120 measures the duration of the operation of each driving support device by using the time counter with the time when the start signal of the operation of each driving support device is acquired as a reference. The operation duration measuring unit 120 outputs, for example, the measured operation duration of each driving support device to the information presentation control unit 140.

The traveling information acquisition unit 130 acquires traveling information regarding traveling of the vehicle, for example. The travel information acquisition unit 130 acquires, for example, video data from the imaging unit 20 as the travel information. The traveling information acquisition unit 130 acquires, for example, current position information from the GPS reception unit 30 as traveling information. In this case, the traveling information acquisition unit 130 acquires, for example, the map information 11 corresponding to the current position information from the storage unit 10. Accordingly, the traveling information acquisition unit 130 acquires information such as a sign around the vehicle M, information about other vehicles traveling around the vehicle M, and a building name existing around the vehicle. The traveling information acquisition unit 130 outputs the acquired various information to the information presentation control unit 140.

The information presentation control unit 140 presents various information by the information presentation unit 40. The information presentation control unit 140 presents the presentation information by the information presentation unit 40, for example. In the present embodiment, the presentation information means, for example, information related to the vehicle. More specifically, the presentation information is an instruction to maintain or increase the degree of interest of the driver in driving so as not to decrease the degree of interest. As will be described later, the information presentation control unit 140 is based on at least one of the operation information of each driving support device received from the vehicle information acquisition unit 110 and the operation duration of each driving support device received from the operation duration measurement unit 120. Then, the form of information presentation of the presentation information is controlled.

The information presentation control unit 140 may, for example, present information according to the presence or absence of the operation of each driving support device and the automatic driving level of the vehicle.

The information presentation control unit 140 changes the form of the presentation information to be presented according to the duration of the operation of each driving support device, for example. Specifically, when the presentation information such as traffic information such as traffic jam and route information to the destination is presented by voice, the information presentation control unit 140, for example, according to the operation duration of each driving support device, Each time a predetermined period of time elapses, the voice output of a male voice and the voice output of a female voice may be alternately changed and voice output may be performed. When the time has passed, the sound may be output together with the jingle. When presenting the presentation information such as traffic information such as traffic jam and the information of other vehicles traveling in parallel in the adjacent lane with the light emitting unit, the information presentation control unit 140 emits light according to the duration of the operation of each driving support device, for example. The light emitting unit may emit light by changing the pattern, the light emission intensity, the light emission color, and the like. When presenting the presentation information on the display unit of the car navigation device, the information presentation control unit 140 changes the display color of characters such as the estimated time of arrival at the destination and the name of an intersection to turn left or right, which is displayed on the display unit. Alternatively, presentation information such as lane information to be traveled with any static image or moving image and a service area existing in the traveling direction of the vehicle may be displayed. In this case, the information presentation control unit 140 may change the display color of the character to a prominent color or emphasize the character according to the duration of the operation of each driving support device.

For example, the information presentation control unit 140 may change the presentation information to be presented according to the duration of the operation of each driving support device after the operation of each driving support device starts. The information presentation control unit 140 may change the presentation information to be presented, for example, when the duration of the operation of each driving support device exceeds a predetermined time. The information presentation control unit 140 may shorten the time interval for presenting the presentation information, for example, according to the duration of the operation of each driving support device.

On the other hand, the information presentation control unit 140 may issue an instruction for confirming the surroundings of the vehicle, for example, in accordance with the automatic driving level when the vehicle is performing automatic driving. This is because it is possible that the driver's interest in driving decreases as the vehicle travels with a higher level of automatic driving. Therefore, by actively checking the surroundings of the vehicle, the degree of interest in the driving vehicle increases. At the same time, it is for relieving the driver's physical tension and awakening drowsiness.

The biometric information acquisition unit 150 acquires various biometric information from the biometric information detection unit 50. The biometric information acquisition unit 150 acquires, for example, biometric information of the driver. The biometric information acquisition unit 150 calculates the degree of interest of the driver in driving, for example, based on the acquired biometric information of the driver. Specifically, when calculating the degree of interest in driving based on the line-of-sight information of the driver, the biological information acquisition unit 150 calculates the degree of interest, for example, based on the state of the eyes and the direction of the line of sight. In this case, for example, when the biometric information acquisition unit 150 acquires information that the eyes are closed, the line of sight is fixed, or the line of sight is not stable, the driver may fall asleep, thinking and looking aside. Is determined to be high, and the degree of interest is calculated to be low.

For example, when the biological information acquisition unit 150 calculates the degree of interest in driving, the information presentation control unit 140 may change the form of presenting information according to the degree of interest.

Information presentation according to the degree of interest in driving will be described with reference to FIG. FIG. 3 is a schematic diagram for explaining an example of information presentation according to the degree of interest in driving.

FIG. 3 shows an example of information presentation when the degree of interest in driving is level 5, level 4, and level 3. In FIG. 3, the higher the level, the greater the degree of interest.

When the degree of interest is level 5 and it is considered that the degree of interest in the driver's driving is high, the information presentation control unit 140 displays the map information by the navigation device, for example, as specified by the driver. To display.

When the degree of interest is level 4 and the degree of interest in the driver's interest in driving is considered to be slightly lower, the information presentation control unit 140 presents information about the driving that attracts the driver's interest, for example. To do. Specifically, the information presentation control unit 140 presents information with voices such as "Please look at the scenery seen through the window" and "Please check the room mirror", and the driver can see the scenery seen from the vehicle and running. By confirming the situation, the driver's awakening level is prevented from being lowered and the driver's attention to the TV screen or smartphone screen is prevented, thereby increasing the driver's interest in driving. The information presentation control unit 140 may present the presentation information to the driver at predetermined intervals to increase the degree of interest in driving. When the vehicle is traveling at the automatic driving level 3, the information presentation control unit 140 may present the presentation information by a plurality of different methods to increase the degree of interest in driving. The information presentation control unit 140 may urge the driver to confirm the rearview mirror, for example, by causing a light emitting unit provided in the rearview mirror to emit light.

When the degree of interest is level 3 and the degree of interest in the driver's driving decreases and there is a sign of drowsy driving or drowsy driving, the information presentation control unit 140 responds to the driver, for example. Present the information you are looking for. For example, the information presentation control unit 140 asks the driver to "check the parallel running vehicle with the body sideways", "check the signs in front and in the opposite lane", etc. Instruct the driver to actively check the running condition of the vehicle while controlling drowsiness and aimless driving by moving the body. For example, the information presentation control unit 140 presents information to the driver in a quiz format or a game format. Specifically, the information presentation control unit 140 causes, for example, the color of the vehicle two behind the own vehicle to be answered, or the number of existing vehicles from the current position to the next intersection. The information presentation control unit 140 may change the form of the presentation information by, for example, the method described above when the driver's interest in driving does not increase after the information presentation. In addition, when the degree of interest is level 2 or level 1 and it is recognized that the driver is dozing, even if the volume of the warning is increased, the form of the presentation information is changed, such as increasing the light emission intensity. Good.
