The HMI 6 includes an input device that accepts the operation of the occupant and a display device that presents information to the occupant. The HMI 6 is, for example, a touch panel in which a touch sensor and a display are integrated.

The control device 10 includes an occupant recognition unit 11, a vehicle environment recognition unit 12, a setting information processing unit 13, and a setting information storage unit 15.

The occupant recognition unit 11 analyzes the image captured by the in-vehicle camera 2 and recognizes each occupant present in the vehicle. In addition, the occupant recognition unit 11 analyzes the image and recognizes the age and gender of each occupant. The occupant recognition unit 11 generates occupant information including the recognized identification number, age, gender, and seat of each occupant, and outputs the generated occupant information of each occupant to the setting information processing unit 13.

The vehicle environment recognition unit 12 acquires information indicating the speed of the vehicle from the ECU 3. Further, the vehicle environment recognition unit 12 acquires information indicating the position of the vehicle and the current date and time from the GPS receiver 4. Further, the vehicle environment recognition unit 12 acquires information indicating a device connected to the in-vehicle audio device 1 from the setting information management unit 14. The vehicle environment recognition unit 12 outputs these acquired information to the setting information processing unit 13 as vehicle environment information.

The setting information management unit 14 acquires information indicating the volume, sound quality, and music source set by the occupant for the vehicle-mounted audio device 1 from the vehicle-mounted audio device 1. The information indicating the sound quality is, for example, the information of the equalizer. The setting information management unit 14 outputs information indicating the volume, sound quality, and music source acquired from the in-vehicle audio device 1 to the setting information processing unit 13 as setting information.

Further, the setting information management unit 14 controls the volume and sound quality of the vehicle-mounted audio device 1 by outputting the setting information indicating the volume and sound quality instructed by the setting information processing unit 13 to the vehicle-mounted audio device 1. The setting information management unit 14 switches the music source to be played by outputting the setting information indicating the music source instructed by the setting information processing unit 13 to the in-vehicle audio device 1.

The setting information processing unit 13 acquires occupant information from the occupant recognition unit 11. The setting information processing unit 13 acquires vehicle environment information from the vehicle environment recognition unit 12. The setting information processing unit 13 acquires the setting information from the setting information management unit 14. The setting information processing unit 13 stores the acquired occupant information, vehicle environment information, and setting information in the setting information storage unit 15 in association with each other.

The setting information processing unit 13 acquires information from the occupant recognition unit 11, the vehicle environment recognition unit 12, and the setting information management unit 14 at a predetermined cycle, and associates the acquired information with the setting information storage unit. It is preferable to store it in 15. As a result, the setting information having the same contents is stored in the plurality of setting information processing units 13. The setting information processing unit 13 determines the priority based on the number of setting information having the same contents stored in the setting information storage unit 15. That is, the setting information processing unit 13 treats the setting information storage unit 15 as having a higher priority as the number of setting information having the same content is larger. The setting information processing unit 13 may store the determined priority in the setting information storage unit 15 in association with the setting information. Further, the setting information processing unit 13 preferably deletes the oldest setting information in order in order to prevent the setting information storage unit 15 from increasing in capacity and to delete the setting information related to the device that has not been used for a long time.

Further, when the setting information processing unit 13 determines that the occupant in the vehicle has been changed based on the occupant information, the setting information storage unit 15 reads the setting information corresponding to the changed occupant information from the setting information storage unit 15. The change of occupants is a change in the number of occupants or a replacement of occupants due to the occupants getting on or off. For example, when the number of occupants increases from one to two, the setting information processing unit 13 reads out the setting information associated with the occupant information including the identification numbers of the two occupants from the setting information storage unit 15. At that time, the setting information processing unit 13 sets the occupant information when there is no occupant information whose identification number matches, that is, because the occupant currently in the vehicle has never boarded the vehicle in the past. If it does not exist in the storage unit 15, the setting information associated with the occupant information that matches at least one of the age and the gender may be read out.

When the setting information processing unit 13 determines that the vehicle environment has changed based on the vehicle environment information, the setting information storage unit 13 reads the setting information corresponding to the changed vehicle environment information from the setting information storage unit 15. The change in the vehicle environment is a change in at least one of device information, music source, sound quality, volume, current date and time, vehicle speed, or position set in the setting information management unit 14. The setting information processing unit 13 can change the volume and sound quality of the in-vehicle audio device 1 by considering the music source set by the setting information management unit 14 as a change in the vehicle environment. Further, the setting information processing unit 13 considers the current date and time as a change in the vehicle environment, so that the volume, sound quality, and sound quality of the in-vehicle audio device 1 can be adjusted for each time zone such as morning, noon, and night, or for each day of the week such as weekdays and holidays. And the music source can be changed. Further, the setting information processing unit 13 considers the speed of the vehicle as a change in the vehicle environment, so that the volume, sound quality, and music source of the in-vehicle audio device 1 can be adjusted according to the magnitude of the road noise that changes according to the speed. Will be able to change. Further, the setting information processing unit 13 can change the volume, sound quality, and music source of the in-vehicle audio device 1 between traveling on a general road and traveling on an expressway by considering the position of the vehicle. ..

For example, when the music source set by the setting information management unit 14 changes from the USB memory to the radio receiver, the setting information processing unit 13 reads the setting information corresponding to the radio receiver from the setting information storage unit 15. Further, for example, when the current date and time shifts to any of the morning, noon, and night time zones, the setting information processing unit 13 reads the setting information corresponding to the time zone after the shift from the setting information storage unit 15. Further, for example, when the current date and time shifts from a weekday to a holiday, the setting information processing unit 13 reads the setting information corresponding to the holiday after the shift from the setting information storage unit 15. Further, for example, when the setting information processing unit 13 determines that the road type (general road or expressway, etc.) on which the vehicle is traveling has changed based on the position or speed of the vehicle, it corresponds to the changed position or speed. The setting information to be set is read from the setting information storage unit 15.

When the setting information processing unit 13 determines that the occupant has changed and the vehicle environment has also changed, the setting information processing unit 13 sets the changed occupant information and the setting information corresponding to the changed vehicle environment information. It may be read from the storage unit 15. When the setting information processing unit 13 determines that the occupant has not changed and only the vehicle environment has changed, the setting information storage unit 15 reads the current occupant information and the setting information corresponding to the changed vehicle environment information from the setting information storage unit 15. Just put it out. When the setting information processing unit 13 determines that the occupant has changed and the vehicle environment has not changed, the setting information storage unit 15 reads the changed occupant information and the setting information corresponding to the current vehicle environment information from the setting information storage unit 15. Just put it out.

The setting information processing unit 13 has the largest number of setting information (that is, the highest priority) among one or more setting information read from the setting information storage unit 15 when the occupant is changed or the vehicle environment is changed. High setting information) is selected, and the selected setting information is output to the setting information management unit 14. The setting information processing unit 13 may use the HMI 6 to inquire of the occupant whether or not the setting can be changed before outputting the selected setting information to the setting information management unit 14.

FIG. 2 is a flowchart showing an example of collecting setting information by the control device 10 of the in-vehicle audio device 1 according to the first embodiment. The control device 10 performs the operation shown in the flowchart of FIG. 2 while the in-vehicle audio device 1 is operating.

In step ST11, the setting information processing unit 13 determines whether or not the predetermined timing has been reached. The predetermined timing is a predetermined cycle such as a 30-minute cycle or a 1-hour cycle.

When the predetermined timing is reached (step ST11 “YES”), the setting information processing unit 13 sets the occupant information from the occupant recognition unit 11 and the vehicle environment information from the vehicle environment recognition unit 12 in step ST12. The setting information is acquired from the information management unit 14. If the timing is not set in advance (step ST11 “NO”), the process of the setting information processing unit 13 returns to step ST11.

In step ST13, the setting information processing unit 13 stores the occupant information, the vehicle environment information, and the setting information acquired in step ST12 in the setting information storage unit 15 in association with each other.

In addition, when the setting information processing unit 13 determines that the occupant has changed based on the occupant information from the occupant recognition unit 11, or the vehicle environment has changed based on the vehicle environment information from the vehicle environment recognition unit 12. If it is determined that the timing has been determined in advance (step ST11 “YES”), setting information and the like may be acquired (step ST12).

FIG. 3 is a flowchart showing an example of changing the setting of the in-vehicle audio device 1 by the control device 10 according to the first embodiment. The control device 10 repeats the operation shown in the flowchart of FIG. 3 while the in-vehicle audio device 1 is operating. Further, the control device 10 may perform the operation shown in the flowchart of FIG. 2 and the operation shown in the flowchart of FIG. 3 in parallel.

In step ST21, the setting information processing unit 13 determines whether or not the occupant has been changed based on the occupant information from the occupant recognition unit 11. Further, the setting information processing unit 13 determines whether or not the vehicle environment has changed based on the vehicle environment information from the vehicle environment recognition unit 12. If there is a change in the occupant, if there is a change in the vehicle environment, or if there is a change in the occupant or a change in the vehicle environment (step ST21 “YES”), the processing of the setting information processing unit 13 proceeds to step ST22. .. On the other hand, if there is no change in the occupant or the vehicle environment (step ST21 “NO”), the process of the setting information processing unit 13 returns to step ST21.

In step ST22, the setting information processing unit 13 reads out the setting information corresponding to the changed occupant information and the vehicle environment information from the setting information storage unit 15. The setting information processing unit 13 selects the setting information having the largest number (that is, the setting information having the highest priority) from the one or more setting information read from the setting information storage unit 15.

In step ST23, the setting information processing unit 13 confirms whether or not a device capable of providing the music source indicated by the setting information having the highest priority is connected to the in-vehicle audio device 1. When a device capable of providing the music source indicated by the setting information having the highest priority is connected (step ST23 “YES”), the process of the setting information processing unit 13 proceeds to step ST24. On the other hand, when a device capable of providing the music source indicated by the setting information having the highest priority is not connected (step ST23 “NO”), the process of the setting information processing unit 13 returns to step ST22. In that case, the setting information processing unit 13 reads out the second highest priority setting information corresponding to the changed occupant information and the vehicle environment information from the setting information storage unit 15 (step ST22), and the read-out setting. It is confirmed whether or not a device capable of providing the music source indicated by the information is connected (step ST23).

In step ST24, the setting information processing unit 13 confirms whether or not the automatic setting is permitted by the occupant. Whether or not the automatic setting is possible may be set in the setting information processing unit 13 in advance by the occupant operating the HMI 6. When the automatic setting is permitted (step ST24 “YES”), in step ST25, the setting information processing unit 13 outputs the setting information read in step ST22 to the setting information management unit 14. The setting information management unit 14 controls the volume and sound quality of the vehicle-mounted audio device 1 by outputting the setting information indicating the volume and sound quality among the setting information from the setting information processing unit 13 to the vehicle-mounted audio device 1. Further, the setting information management unit 14 switches the music source to be played by the vehicle-mounted audio device 1 by outputting the setting information indicating the music source among the setting information from the setting information processing unit 13 to the vehicle-mounted audio device 1.

In step ST26, the setting information processing unit 13 stores the current occupant information and the vehicle environment information in association with the setting information read in step ST22 in the setting information storage unit 15.

If automatic setting is not permitted (step ST24 “NO”), in step ST27, the setting information processing unit 13 instructs the HMI 6 to display a setting notification screen for inquiring the occupant whether or not the setting has been changed. Upon receiving this instruction, the HMI 6 displays the setting notification screen and accepts the input operation of the setting change by the occupant. The HMI 6 notifies the setting information processing unit 13 whether or not the setting can be changed.

When the occupant permits the setting change (step ST28 “YES”), the process of the setting information processing unit 13 proceeds to step ST25. In this case, the setting information processing unit 13 outputs the setting information read in step ST22 to the setting information management unit 14.

On the other hand, if the occupant does not permit the setting change (step ST28 “NO”), the process of the setting information processing unit 13 proceeds to step ST26. In this case, the setting information processing unit 13 stores the current occupant information, the vehicle environment information, and the information that the setting cannot be changed in association with the setting information read in step ST22 in the setting information storage unit 15. The setting information processing unit 13 evaluates the priority of the setting information to which the information that cannot be changed is associated with the setting low, thereby making it difficult for the occupant to select the setting information for which the setting change is not permitted in the past.

Here, a screen display example of the HMI 6 in steps ST24 to ST28 will be described.
4A and 4B are diagrams showing an example of a setting notification screen displayed by HMI6. When the automatic setting is permitted in step ST24, the setting information processing unit 13 displays the setting notification screen as shown in FIG. 4A on the HMI 6 and then proceeds to the process of step ST25.

On the other hand, when the automatic setting is not permitted in step ST24, the setting information processing unit 13 causes the HMI 6 to display the setting notification screen as shown in FIG. 4B in step ST27. When the "permit" icon is selected and operated by the occupant, the setting information processing unit 13 determines that the occupant has permitted the setting change (step ST28 "YES"). When the "Cancel" icon is selected and operated by the occupant, the setting information processing unit 13 determines that the occupant has not permitted the setting change (step ST28 "NO"). When the "details" icon is selected by the occupant, the setting information processing unit 13 causes the HMI 6 to display a detailed selection screen showing the setting information selected in step ST22.

5A and 5B are diagrams showing an example of a detailed selection screen displayed by HMI6. When the "details" icon of FIG. 4B is selected, the setting information processing unit 13 causes the HMI 6 to display the detailed selection screen as shown in FIG. 5A. The setting information exemplified in FIG. 5A includes the music source "USB", the adopted device "USB of slot No. 1", and the volume "15". That is, the setting information of this example is the slot No. of the in-vehicle audio device 1. The content is that the music data stored in the USB memory connected to 1 is played back at a volume of "15". When the "permit" icon is selected and operated by the occupant, the setting information processing unit 13 determines that the occupant has permitted the setting change (step ST28 "YES"). When the "Cancel" icon is selected and operated by the occupant, the setting information processing unit 13 determines that the occupant has not permitted the setting change (step ST28 "NO").

The setting information exemplified in FIG. 5B includes the music source "Bluetooth", the adopted device "Mr. A's smartphone", the communication permission "music on, call off", and the volume "10". That is, the setting information in this example reproduces the music data stored in Mr. A's smartphone connected to the in-vehicle audio device 1 via Bluetooth at a volume of "10" and is hands-free using Mr. A's smartphone. The content is to turn off the call function. When the "permit" icon is selected and operated by the occupant, the setting information processing unit 13 determines that the occupant has permitted the setting change (step ST28 "YES"). When the "Cancel" icon is selected and operated by the occupant, the setting information processing unit 13 determines that the occupant has not permitted the setting change (step ST28 "NO").

Next, a specific example will be described.
In this example, it is assumed that Mr. A is seated in the driver's seat and Mr. B is seated in the passenger seat. It is assumed that the in-vehicle audio device 1 is operating based on the setting information shown in FIG. 5B.
In this state, when the vehicle stops and Mr. B gets off, the setting information processing unit 13 determines that the occupant has changed based on the occupant information. Then, the setting information processing unit 13 reads out the setting information having the highest priority among the setting information corresponding to the occupant information of Mr. A from the setting information storage unit 15. Here, the setting information read from the setting information storage unit 15 by the setting information processing unit 13 is the music source "Bluetooth", the adopted device "Mr. A's smartphone", the communication permission "music on, call on", and the volume "10". It is assumed that the content was. The only change from the setting information shown in FIG. 5B to the newly read setting information is the change from the communication permission "call off" to "call on". Based on this setting information, the setting information management unit 14 turns on the HFP, which is the communication profile of the device Bluetooth-connected to the in-vehicle audio device 1.

If the place where Mr. B got off is crowded, changing the setting of the in-vehicle audio device 1 can be stressful for Mr. A, who is the driver. The burden on the driver can be reduced by the control device 10 executing the setting change of the in-vehicle audio device 1 on behalf of the driver. Further, when Mr. A frequently used the hands-free call function in his / her own vehicle in the past, the information is stored in the setting information storage unit 15, so that the control device 10 is desired by Mr. A. It is possible to change the setting of the in-vehicle audio device 1 suitable for

If the occupant information includes not only the identification number, age, and gender but also the seat, the occupant information when Mr. A is seated in the driver's seat and Mr. B is seated in the passenger seat, and Mr. B is driving. It is treated as a separate item from the occupant information when Mr. A is seated in the passenger seat. Therefore, the setting information read from the setting information storage unit 15 by the setting information processing unit 13 differs depending on the seats in which Mr. A and Mr. B are seated. Therefore, the control device 10 can change the setting of the in-vehicle audio device 1 according to the combination of the occupant and the seat.

Next, another example will be described.
In this example, it is assumed that Mr. A is seated in the driver's seat and Mr. C (10 years old) is seated in the passenger seat. It is assumed that the in-vehicle audio device 1 is operating based on the setting information shown in FIG. 5A.
In this state, when the vehicle stops and Mr. C gets off, the setting information processing unit 13 performs the music source "Bluetooth", the adopted device "Mr. A's smartphone", and the communication permission "Music on" as in the above example. , Call on ”and volume“ 10 ”are read from the setting information storage unit 15. The setting information management unit 14 changes the volume of the in-vehicle audio device 1 to "10" based on this setting information, and turns on A2DP and HFP, which are communication profiles of the devices Bluetooth connected to the in-vehicle audio device 1. ..
After that, when Mr. D (10 years old) gets on board, the setting information processing unit 13 determines that the occupant has changed based on the occupant information. However, when the occupant information matching the identification number of Mr. D does not exist in the setting information storage unit 15, the setting information processing unit 13 diverts the occupant information of Mr. C who has the same or similar age as Mr. D, and Mr. A. And the setting information corresponding to the occupant information of Mr. C is read from the setting information storage unit 15. The setting information corresponding to the occupant information of Mr. A and Mr. C is the setting information shown in FIG. 5A. Based on this setting information, the control device 10 can automatically change the setting to the music source that was played when there was a child in the car in the past.

Next, the hardware configuration of the in-vehicle audio device 1 and the control device 10 according to the first embodiment will be described.
