[0019] Figure 4 A diagram for explaining a comparative example of one example of the embodiment of the present disclosure. DETAILED DESCRIPTION

[0020] First, the development history of an example of an embodiment of the present disclosure will be described. Figure 4 It is a diagram showing a schematic configuration of an information processing device of a comparative example which is one example of the embodiment of the present disclosure.

[0021] Figure 4 The information processing device 1B shown is a device installed on the vehicle, and is a device that receives a sound request such as a buzzer from each system installed on the vehicle via a CAN (Controller Area Network), analyzes the sound request, and outputs a sound instruction to emit a buzzer or other sound from a speaker (not shown).

[0022] The information processing device 1B is composed of an MCU 10 and a SoC 20B. The MCU 10 and the SoC 20B are respectively provided with a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), a storage device, and a communication interface (I / F). The information processing device 1B is provided with an MCU 10 for real-time performance, responsiveness, and power management, and is provided with a SoC 20B for general processing such as two-dimensional or three-dimensional graphics processing.

[0023] As a functional structure, the MCU 10 includes a CAN communication unit 11 , an application storage unit 12 , and a mediation unit 13 .

[0024] The CAN communication unit 11 receives various requests from various systems installed in the vehicle via the CAN. In particular, the CAN communication unit 11 receives a chime request from various systems installed in the vehicle. If the chime request is for an application stored in the MCU 10, the CAN communication unit 11 sends the chime request to the application storage unit 12. If the chime request is for an application stored in the SoC 20B, the CAN communication unit 11 sends the chime request to the SoC 20B.

[0025] The application storage unit 12 stores one or more applications for sounding a buzzer. Figure 4 In the example of , the application storage unit 12 stores two applications (App) 12A and 12B. Each application outputs a sounding instruction when a sounding request for the application is sent from the CAN communication unit 11. Each application stored in the application storage unit 12 is an application for sounding a safety buzzer that needs to be sounded immediately. As a safety buzzer that needs to be sounded immediately, there is a buzzer for notifying an occupant that he or she is not wearing a seat belt. In addition, the application storage unit 12 cannot be updated from the outside.

[0026] The mediation unit 13 mediates the ringing instructions from each application stored in the application storage unit 12, and outputs a ringing instruction through the CAN communication unit 11. When mediating the ringing instructions from each application, the mediation unit 13 determines which buzzer sound is to be sounded according to the priority of the ringing. The mediation unit 13 obtains the priority of the ringing by referring to the priority table stored in the MCU 10, for example.

[0027] As a functional structure, the SoC 20B includes an inter-microcomputer communication unit 21 and an application storage unit 22 .

[0028] The inter-microcomputer communication unit 21 communicates data with the MCU 10 . In particular, the inter-microcomputer communication unit 21 receives a ringing request sent from the MCU 10 .

[0029] The application storage unit 22 stores one or more applications for sounding a buzzer. Figure 4 In the example of FIG. 1 , the application storage unit 22 stores two applications (App) 22A and 22B. Each application outputs a ringing instruction when a ringing request for the application is sent from the inter-microcomputer communication unit 21. The ringing instruction from the application stored in the application storage unit 22 is sent to the MCU 10 via the inter-microcomputer communication unit 21.

[0030] In addition, the application storage unit 22 can be updated from the outside. That is, the application stored in the application storage unit 22 can be updated or added from the outside through OTA (Over The Air). Figure 4 In the example of , the application 22C is added to the application storage unit 22 by OTA. In addition, although the SoC 20B can update or add the application by OTA, the MCU 10 is configured so that the application cannot be updated or added.

[0031] Here, when the application 22C is added to the application storage unit 22 via OTA, the MCU 10 cannot recognize the ringing instruction implemented by the added application 22C. This is because the table referenced by the mediation unit 13 does not contain information related to the priority of the ringing instruction of the added application 22C, so even if the mediation unit 13 receives the ringing instruction of the application 22C, it does not know how to mediate.

[0032] Therefore, in the embodiment of the present disclosure, an information processing device that can recognize a ringing instruction from an application program added to the SoC by the MCU 10 will be described.

[0033] Hereinafter, an example of an embodiment of the present disclosure will be described with reference to the accompanying drawings. In addition, in each of the drawings, the same reference symbols are used for the same or equivalent structural elements and parts. In addition, for the convenience of description, the dimensional ratios of the drawings are exaggerated and sometimes different from the actual ratios.

[0034] Figure 1 It is a diagram showing a schematic configuration of an information processing device according to the present embodiment. Figure 1 The information processing device 1A shown in FIG. Figure 4The information processing device 1B shown is similar to the one installed in the vehicle, and is a device that receives a buzzer sound request from each system installed in the vehicle via CAN, analyzes the buzzer sound request, and outputs a buzzer sound instruction to emit a buzzer sound from a speaker (not shown).

[0035] The information processing device 1A is composed of MCU10 and SoC20A. MCU10 and SoC20A respectively have CPU, ROM, RAM and communication interface (I / F). CPU is a central processing unit, and executes various programs or controls various parts. That is, CPU reads programs from ROM or storage, and uses RAM as a work area to execute programs. CPU controls the above-mentioned structures and performs various calculations according to the programs stored in ROM. In this embodiment, an information processing program for processing ringing requests from the outside is stored in ROM. ROM stores various programs and various data. RAM temporarily stores programs or data as a work area.

[0036] The information processing device 1A has an MCU 10 for immediacy, responsiveness, and power management, and has an SoC 20A for general processing such as two-dimensional or three-dimensional graphics processing. The MCU 10 is a non-rewritable device and is an example of the first device of the present disclosure. The SoC 20A is a rewritable device and is an example of the second device of the present disclosure.

[0037] As a functional structure, the MCU 10 includes a CAN communication unit 11, an application storage unit 12, and a mediation unit 13. Figure 4 The contents described in the MCU 10 of the information processing device 1B are the same as those described above, and thus detailed descriptions are omitted. The number of application programs stored in the application program storage unit 12 is one or more.

[0038] As a functional structure, the SoC 20A includes an inter-microcomputer communication unit 21 , an application storage unit 22 , and a reference unit 23 .

[0039] The inter-microcomputer communication unit 21 communicates data with the MCU 10 . In particular, the inter-microcomputer communication unit 21 receives a ringing request sent from the MCU 10 .

[0040] The application storage unit 22 stores one or more applications for sounding a buzzer. Figure 1 In the example of FIG. 1 , the application storage unit 22 stores two applications (App) 22A and 22B. When a ringing request for the application is sent from the inter-microcomputer communication unit 21 , each application outputs a ringing instruction to the reference unit 23 .

[0041] The applications stored in the application storage unit 22 can be updated or added from the outside via OTA. Figure 1 In the example of , application 22C is added to application storage unit 22 via OTA. Figure 4 Similarly to the information processing device 1B, although the SoC 20A can update or add an application program through OTA, the MCU 10 is configured so that the application program cannot be updated or added.

[0042] When the reference unit 23 obtains the ringing instruction from the application stored in the application storage unit 22, it refers to a table recording a list of buzzer sounds defined by identifiers determined according to the priority and the sound type. The table is recorded in the SoC 20A. Moreover, the reference unit 23 refers to the table and outputs the ringing instruction of the buzzer sound with a high priority to the MCU 10 through the inter-microcomputer communication unit 21. In the MCU 10, the reference result of the reference unit 23 is obtained by the mediation unit 13. Therefore, the mediation unit 13 can also function as the acquisition unit of the present disclosure.

[0043] Figure 2 FIG. 2 is a diagram showing an example of a table referenced by the reference unit 23. In the table, a unique request ID is set according to the priority and the sound type of the buzzer sound. That is, the request ID is an ID determined based on the priority and is an example of an identifier of the present disclosure. When the reference unit 23 obtains a buzzer instruction from an application stored in the application storage unit 22, it refers to the request ID. Figure 2 The table shown in FIG. 1 outputs a request ID corresponding to the buzzer sound as an instruction to sound a buzzer sound with a high priority. The request ID is used for mediation in the mediation unit 13.

[0044] For example, when the application programs 22A, 22B, and 22C output the alarm instructions at the same timing, the reference unit 23 refers to Figure 2 The table shown in FIG. 2 outputs the request ID as a buzzer sound indication with a high priority. In other words, the reference unit 23 abstracts the buzzer indication from the application stored in the application storage unit 22 and outputs it to the MCU 10. To abstract the buzzer indication specifically means to abstract it into a sound type predetermined by the SoC 20A. By abstracting the buzzer indication from the application stored in the application storage unit 22, the mediation unit 13 can recognize the buzzer indication from the added application even if an application is added to the SoC 20A.

[0045] With this configuration, the information processing device 1A according to the embodiment of the present disclosure can recognize a sound instruction from an application program that sounds a buzzer and sound the buzzer even when an application program that sounds a buzzer is added or updated.

[0046] Next, the operation of the information processing device 1A will be described.

[0047] Figure 3 1A is a flowchart showing the flow of information processing performed by the information processing device 1A. The information processing is performed by the CPU of the MCU 10 and the SoC 20A reading the information processing program from the ROM or the memory, expanding it in the RAM, and executing it.

[0048] When the information processing device 1A receives a request to sound a buzzer sound from each system installed in the vehicle via the CAN, the MCU 10 determines in step S101 whether a request to sound a buzzer sound is received from an application on the SoC 20A side.

[0049] When the result of the judgment in step S101 is that the ringing request includes the application on the SoC20A side (step S101: Yes), then, in step S102, the information processing device 1A refers to the table recorded in SoC20A in order to adjust the ringing indication based on the ringing request of the application on the SoC20A side.

[0050] Following step S102 , in step S103 , the information processing device 1A refers to the result of the table, obtains the request ID of the beep sound with the highest priority, and outputs it from the SoC 20A to the MCU 10 .

[0051] Following step S103, in step S104, the information processing device 1A adjusts the ringing instructions from the application on the MCU10 side and the application on the SoC20A side through the MCU10. In addition, if the result of the judgment in step S101 is that the ringing request from the application on the SoC20A side is not included (step S101: No), then, in step S104, the information processing device 1A adjusts the ringing instructions from the application on the MCU10 side through the MCU10.

[0052] Following step S104, in step S105, the information processing apparatus 1A outputs a ringing instruction as a result of the adjustment of the ringing instruction.

[0053] By executing such processing, the information processing device 1A according to the embodiment of the present disclosure can recognize a sound instruction from the application and sound the buzzer even when an application for sounding the buzzer is added or updated.
