Document Type and Number:
Japanese Patent JP6508067
Kind Code:
B2
Abstract:
When a verification result by a verifier is a success, an electronic control unit activates a rewriting target program stored in a second storage, and transmits a verification result reply signal that indicates that the verification result is a success to a relay apparatus. When a verification result by the verifier is a failure, the electronic control unit activates a communication control program stored in a first storage, and transmits a verification result reply signal that indicates that the verification result is a failure to the relay apparatus. Upon receiving the verification result reply signal that indicates that the verification result is a success, the relay apparatus identifies a correct rewriting operation with the rewriting target program. In contrast, upon receiving the verification result reply signal that indicates that the verification result is a failure, the relay apparatus identifies an incorrect rewriting operation with the rewriting target program.
