The start-up process is a process that is started when a power supply voltage is applied to the HCU 2. When the expansion module 3 is connected to the HCU 2 via the USB connector 14, when the power supply voltage is applied to the HCU 2, the power supply voltage is also applied to the expansion module 3 via the USB connector 14. As a result, the CPU 41 of the expansion module 3 starts, and the CPU 41 starts the OS 91.

When the startup process is executed, the CPU 21 of the HCU 2 first executes the startup process of starting the CPU 21 in S10, as shown in FIG.

Then, in S70, the CPU 21 determines whether or not the service bus 82 is connected to the external OS (that is, OS91) of the HCU2. Here, if it is not connected to the external OS, the CPU 21 ends the startup process. On the other hand, when connected to the external OS, the CPU 21 allocates resources to the external OS in S80 and ends the startup process. Specifically, the CPU 21 sets a storage area in the RAM 23 for temporarily storing the data received from the expansion module 3.

Next, the procedure of the function expansion process executed by the CPU 41 of the expansion module 3 will be described. The function expansion process is a process started after the expansion module 3 is connected to the HCU 2 and the OS 91 is started.

When the function expansion process is executed, the CPU 41 first determines in S110 whether or not the expansion module 3 is connected to the HCU 2 for the first time, as shown in FIGS. 6 and 7. Here, when the expansion module 3 is connected to the HCU 2 more than once, the CPU 41 ends the function expansion process.

On the other hand, when the expansion module 3 is connected to the HCU 2 for the first time, the CPU 41 receives the vehicle configuration information CI from the HCU 2 by USB communication in S120.
Further, the CPU 41 sets the item group instruction value i provided in the RAM 43 to 1 in S130.

Then, in S140, the CPU 41 determines in S140 whether or not the vehicle model name (that is, the second item) in the i-th item group of the application information API matches the vehicle model name in the vehicle config information CI. Here, if the vehicle model names do not match, the CPU 41 shifts to S220.

On the other hand, when the vehicle model names match, the CPU 41 in S150, the direction in the i-th item group of the application information API (that is, the third item) matches the direction in the vehicle config information CI. Judge whether or not. Here, if the destinations do not match, the CPU 41 shifts to S220.

On the other hand, if the destinations match, in S160, does the CPU 41 match the grade in the i-th item group of the application information API (that is, the fourth item) with the grade in the vehicle config information CI? Judge whether or not. Here, if the grades do not match, the CPU 41 shifts to S220.

On the other hand, when the grades match, the CPU 41 matches the mounting function (that is, the fifth item) in the i-th item group of the application information API with the mounting function in the vehicle config information CI in S170. Judge whether or not it is. Here, if the mounted functions do not match, the CPU 41 shifts to S220.

On the other hand, when the mounted functions match, the CPU 41 determines in S180 that the resolution of the display in the i-th item group of the application information API (that is, the sixth item) is the resolution of the display in the vehicle config information CI. To determine if it matches. Here, if the resolutions do not match, the CPU 41 shifts to S220.

On the other hand, when the resolutions match, in S190, the CPU 41 sets the size of the display in the i-th item group of the application information API (that is, the seventh item) to the size of the display in the vehicle config information CI. Determine if they match. Here, if the sizes do not match, the CPU 41 shifts to S220.

On the other hand, when the sizes match, in S200, the CPU 41 sets the steering position (that is, the eighth item) in the i-th item group of the application information API to the steering position in the vehicle config information CI. Determine if they match. Here, if the steering positions do not match, the CPU 41 shifts to S220.

On the other hand, when the steering positions match, the CPU 41 sets 1 in the availability item (that is, the 9th item) in the i-th item group of the application information API in S210, and sets S220. Transition. In addition, 0 is set as an initial value in the item of availability.

After shifting to S220, the CPU 41 determines whether or not the item group indicated value i is the number of programs n or more. Here, when the item group indicated value i is less than the number of programs n, the CPU 41 increments (that is, adds 1) the item group indicated value i in S230 to shift to S140.

On the other hand, when the item group indicated value i is the number of programs n or more, the CPU 41 sets the item group indicated value i to 1 in S240.
Then, the CPU 41 determines in S250 whether or not the function expansion application program (hereinafter, function expansion application program PGi) corresponding to the i-th item group is available. Specifically, the CPU 41 determines whether or not 1 is set in the availability item (that is, the ninth item) in the i-th item group of the application information API. That is, the CPU 41 determines that the function expansion application program PGi can be used when the availability item is set to 1. On the other hand, when the availability item is set to 0, it is determined that the function expansion application program PGi is not available.

Here, when the function expansion application program PGi is not available, the CPU 41 shifts to S290. On the other hand, when the function expansion application program PGi is available, the CPU 41 determines in S260 whether or not the function expansion application program PGi is compressed.

Here, when the function expansion application program PGi is not compressed, the CPU 41 shifts to S280. On the other hand, when the function expansion application program PGi is compressed, the CPU 41 expands the function expansion application program PGi in S270 and shifts to S280.

Then, when shifting to S280, the CPU 41 installs the function expansion application program PGi in OS91 and shifts to S290. As a result, the function expansion application program PGi becomes available on OS91.

Then, upon shifting to S290, the CPU 41 determines whether or not the item group indicated value i is the number of programs n or more. Here, when the item group indicated value i is less than the number of programs n, the CPU 41 increments the item group indicated value i in S300 and shifts to S250.

On the other hand, when the item group instruction value i is the number of programs n or more, the CPU 41 deletes the function expansion application program corresponding to the item group in which the availability item is set to 0 in S310 from the flash ROM 44. Then, the function expansion process is terminated.

Next, the control of the center display 51, the meter display 52, the head-up display 53, the air conditioner controller display 54, and the speaker 55 by the HCU2 will be described.

As shown in FIG. 8, the data acquired by the camera 61 taking a picture is input to the meter processing unit 85.

The control unit 32 sets the selected function expansion application program into a state in which it can be executed on the OS 91 by installing it on the OS 91.
In this way, in the vehicle control system 1, data communication can be performed between the HCU 2 and the expansion module 3 to control the equipment mounted on the vehicle. Since the application that operates on the HCU 2 (hereinafter, the first application) and the application that operates on the expansion module 3 (hereinafter, the second application) are different, the first application and the second application mutually interact with each other. There is little data to use while exchanging. Therefore, the vehicle control system 1 can suppress an increase in the amount of data transmitted and received between the HCU 2 and the expansion module 3. As a result, the vehicle control system 1 is mounted on the vehicle by connecting the HCU 2 and the expansion module 3 using communication having lower communication performance than the communication by the bus lines 27 and 47 inside the control units 12 and 32.

Further, the expansion module 3 determines whether or not the connection between the HCU 2 and the expansion module 3 is the first time when the expansion module 3 is connected to the HCU 2 by data communication. Then, when it is determined that the connection between the HCU 2 and the expansion module 3 is not the first time, the expansion module 3 prohibits the acquisition of the vehicle config information CI, the selection of the function expansion application program, and the installation of the function expansion application program. As a result, the vehicle control system 1 can avoid the unnecessary execution of the processing that the function expansion application program is installed even though the function expansion application program is already installed, and can reduce the processing load of the expansion module 3.

Further, the expansion module 3 deletes the unselected function expansion application program from the flash ROM 44.
