Abstract: An object of the present invention is to provide a diagnostic server that can easily diagnose whether an abnormality occurring in a vehicle is a result of an attack or simply a malfunction. A diagnostic server 1 of the present invention includes a log acquisition unit 13 that acquires a history of a first log indicating whether an ECU 32 in a vehicle 3 executes predetermined processing in response to a request signal that requests the ECU 32 to execute the predetermined processing, and a communication determination unit 15 that, when a non-execution log indicating that the predetermined processing is not executed is included in the history, determines validity of communication used to transmit the request signal corresponding to the non-execution log.

Abstract: The present disclosure provides a vehicle control system capable of safely and forcibly controlling a vehicle. A vehicle control system VCS includes a mode setting unit 56 configured to output a forced mode signal upon receiving a forced control instruction from the outside of a vehicle V via a communication device 30, and a forced operation unit 58 configured to output a forced operation signal of forcibly operating the vehicle V to an operation control unit 20. Further, the vehicle control system VCS includes a signal selection unit 59 configured to allow all the operation signals to pass therethrough before receiving the forced mode signal, and block at least a part of the operation signals and allow the forced operation signal instead of the blocked operation signal to pass therethrough after receiving the forced mode signal. The vehicle control system VCS controls an operation of the vehicle V by controlling the operation control unit 20 based on the operation signal or the forced operation signal passing through the signal selection unit 59.

Abstract: Provided is a transfer device capable of suppressing shortage of memory resources even when the transfer device receives a diagnosis request from an external diagnostic equipment with respect to a plurality of electronic devices. A transfer device 20 receives a diagnosis request that is a message from an external diagnostic equipment 10 to a plurality of ECUs 18 from the external diagnostic equipment 10, and transfers the diagnosis request to some ECUs 18 out of a plurality of ECUs 18. Then, the transfer device 20 receives a diagnosis response that is a message from the ECU18 to the external diagnostic equipment 10 from some ECUs 18, transfers the diagnosis response to the external diagnostic equipment 10 and, thereafter, transfers the diagnosis request to ECUs 18 different from the above-mentioned some ECUs 18.
