Abstract:
1. An electronic control device for a vehicle configured to be able to rewrite a program related to a vehicle control by connecting an external device with the vehicle and by accessing an in-vehicle LAN comprising: a portable authentication terminal separated from the external device and configured to transmit a verification request signal to the in-vehicle LAN; an in-vehicle authenticator connected with the in-vehicle LAN, configured to authenticate the portable authentication terminal and to be able to transmit an authentication result to the in-vehicle LAN, and including a verifier configured to receive the verification request signal from the portable authentication terminal through the in-vehicle LAN and to authenticate the verification request signal by comparing the verification request signal with a predetermined code signal; a repeater configured to relay communication between the external device and the in-vehicle LAN; and a communication authorizer connected to the in-vehicle LAN and configured to authorize the communication between the external device and the in-vehicle LAN through the repeater if receiving the authentication result of a successful authentication of the portable authentication terminal by the in-vehicle authenticator, wherein each of the repeater and the verifier is configured to be a single independent structure, and the repeater and the verifier are connected to each other through a bus of the in-vehicle LAN.
