Assignee: HITACHI ASTEMO, LTD.
Field: Transport (Mechanical engineering)
Classification: CPC G  B  H | IPC B  G

Claim 0:
1. An arithmetic operation device which is connected to a plurality of electronic control units, wherein
one or more electronic control units of the plurality of electronic control units constitute each of functions, and
the arithmetic operation device including:
an external communication unit configured to receive, for each function, function configuration information including first verification information and first identification information of the one or more electronic control units constituting the function;
an acquisition unit configured to acquire version information of software installed on the electronic control unit and second identification information of the electronic control unit from each of the plurality of electronic control units;
a calculation unit configured to calculate, for each function, second verification information by using the version information acquired by the acquisition unit, which is the version information of all the electronic control units constituting the function, and the second identification information of all the electronic control units constituting the function; and
a determination unit configured to determine, for each function, whether or not the first verification information and the second verification information match, wherein

the function configuration information includes a flag indicating that the execution in the case of mismatch is permitted or rejected for each function, and
the arithmetic operation device further includes a stop control unit which stops the function related to the second verification information determined to mismatch when the determination unit determines that the first verification information and the second verification information do not match, the function having a flag indicting that the execution in the case of mismatch is rejected as the flag in the function configuration information,
wherein, when the determination unit determinnes that the first verification information and the second verification information do not match, the stop control unit decides whether or not to restrict the function based on the second identification information indicating which version information does not match for the function related to the second verificatioin information determined to mismatch while referring to function restriction information, the function having a flag indicating that the execution at the time of mismatch is permitted or not.
