In addition, addresses c1, c2,..., Ck, which are start addresses of program portions that are permitted to be executed as branch destination programs in each conditional branch, are stored.

  Returning to FIG. 1, the parameter selection unit 152 of the control execution unit 142 performs the common storage area 130 of the storage device 124 in the execution preparation process executed by the control execution unit 142 when the control program 210 is updated by the program update unit 140. The attribute information 202 stored in is acquired. Then, the parameter selection unit 152 refers to the parameter table 218 included in the control program 210 stored in the individual storage area 132 based on the acquired attribute information 202, and uses it according to the acquired attribute information 202.

  FIG. 5 is a diagram illustrating an example of the parameter list 232. In the illustrated example, the parameter list 232 is stored at a position starting from a predetermined address D1 in the working storage area 134. In this parameter list 232, the addresses d1, d2, which are addresses in the working storage area 134, are followed by the A function code, the B function code, the C function code, and the conditional branch labels 1, 2,. , D3, e1, e2,..., Ek are stored. These addresses d 1, d 2, d 3, e 1, e 2,..., Ek are program parts that are permitted to be executed as an A function module, a B function module, and a C function module (ie, one of the modules 220 or The start address of the storage part of the parameter used for the execution of the program part permitted to be executed as the branch destination corresponding to each conditional branch label and the parameter used for the execution of the plurality of conditional branch labels is shown. Thereby, in the parameter list 232, parameters to be used for executing the program part are stored in association with the program part permitted to be executed.

  Returning to FIG. 1, the program execution unit 154 of the control execution unit 142 executes the control program 210. Further, when a function call or conditional branch for realizing the A function or the like occurs in the control program 210, the program execution unit 154 refers to the jump table 230 and identifies the start address of the program part to be executed. Then, the program execution unit 154 operates to move the process of the control program 210 to the start address of the identified program part.

  More specifically, the program execution unit 154 provides, for example, a software platform (hereinafter simply referred to as a platform) for executing the control program 210, and executes the control program 210 on the platform. The control program 210 calls a function for realizing the A function or the like via the platform, and / or inquires the branch destination address of the platform at the time of conditional branching.

  When the platform provided by the program execution unit 154 receives, for example, a call to the A function module from the control program 210, the platform 220 refers to the jump table 230 and is permitted to execute as the A function module 220 (for example, the module 220a-1), the start address (for example, address b1 in FIG. 4) in the individual storage area 132 is acquired. Then, the processing of the control program 210 is transferred to the module 220 starting from the acquired address, thereby causing the control program 210 to realize the A function.

  When the platform receives an inquiry about a branch destination address for a conditional branch with a specific conditional branch label from the control program 210, the platform refers to the jump table 230 and associates it with the corresponding conditional branch label. The address is returned to the control program 210. For example, when receiving a branch destination query for a conditional branch with the conditional branch label 1 from the control program 210, the platform refers to the jump table 230 shown in FIG. The address c1 is returned to the control program 210. As a result, the control program 210 can move the processing to the program portion starting from the address c1 returned from the platform.

  Accordingly, the processing device 122 is permitted to execute the control program 210 according to the attribute information 202 among the control programs 210 stored in the individual storage area 132 based on the attribute information 202 stored in the common storage area 130. The program part is configured to be selectively executed.

  At the same time, the platform provided by the program execution unit 154 identifies the parameter to be used in executing the A function module in the parameter list 232 in the above scenario, for example, and the address of the identified parameter in the parameter list 232 (for example, , The address d1) in FIG. Thereby, the control program 210 can execute the module 220 (for example, the module 220a-1) permitted to be executed as the A function module while referring to the corresponding parameter in the parameter list 232.

  As a result, the processing device 122 is configured to acquire a parameter defined to be used in accordance with the attribute information 202, and execute the program part permitted to be executed using the acquired parameter. .

  Next, the procedure of the execution preparation process performed by the control execution unit 142 of the processing device 122 will be described with reference to the flowchart shown in FIG. This process starts when the program updating unit 140 updates the control program 210 stored in the individual storage area 132 of the storage device 124.

Next, the execution selection unit 150 identifies a program part that is permitted to be executed according to the attribute information 202 (S102).

  For example, the execution selection unit 150 identifies the module 220 that is permitted to be executed for each of the A function module, the B function module, and the C function module according to the model year in the attribute information 202. As a result, the execution of the module 220 for executing control in accordance with legal regulations and / or industry regulations that are required to be applied at the time corresponding to the model year is permitted, and the host vehicle 100 can operate in compliance with those regulations. Will be done.

  Then, the execution selection unit 150 creates a jump table 230 in which the identified program part is associated with the start address, and writes and stores the jump table 230 at a predetermined address position in the working storage area 134 of the storage device 124. (S104).

  Subsequently, the parameter selection unit 152 constituting the control execution unit 142 of the processing device 122 refers to the attribute information 202 stored in the common storage area 130 of the storage device 124 and the parameter table 218 in the control program 210. (S106). Next, the parameter selection unit 152 specifies, from the parameter table 218, a parameter to be used in executing the program part that is permitted to be executed according to the attribute information 202 (S108).

  For example, the parameter selection unit 152 specifies parameters to be used in each of the A function module, the B function module, and the C function module that are permitted to be executed in accordance with the destination code in the attribute information 202. As a result, the A function module, the B function module, and the C function module that are permitted to be executed are executed using the parameters according to the environmental conditions of the destination, and comply with the related regulations in the destination. The operation can be executed reliably.

  Then, the parameter selection unit 152 creates the parameter list 232 by associating the parameters specified for the program part that is permitted to be executed with the identification code of the corresponding program part, and the work storage area 134 in the storage device 124. (S110). Thereafter, the control execution unit 142 ends the execution preparation process.

It is configured to selectively execute a program portion that executes a function to be executed.

  According to this configuration, in each host vehicle 100, based on the attribute information 202 stored in the storage device 124 of the host vehicle 100, the program portion to be executed in the host vehicle 100 in the control program 210 is selectively selected. Executed. Therefore, the control program 210 can be created as one common program for a plurality of vehicles having different types. In addition, by including in the attribute information 202 information that directly or indirectly indicates the scope of regulations to which the host vehicle 100 should comply, in the host vehicle 100, an appropriate operation according to each regulation to be compliant can be performed. It can be done automatically. Therefore, it is possible to appropriately perform the operation according to each host vehicle 100 from the viewpoint of legal regulations and industry regulations to be complied with without increasing the software development cost and update cost related to the control program 210. it can.

  Further, in the electronic control device 120 of the present embodiment, the processing device 122 acquires, for example, the parameter specified to be used according to the attribute information 202 from the control program 210, and uses the acquired parameter to The program portion that is permitted to be executed is configured to be executed. According to this configuration, the operation of the host vehicle 100 can be more finely controlled in accordance with regulations to be complied with.

  In the electronic control device 120 of the present embodiment, when the processing device 122 receives the update program of the control program 210 together with the update instruction, the processing device 122 stores the update program in the individual storage area 132 by the received update program.
