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.

Abstract: Provided is a gateway device capable of reducing influence on intra-vehicle network communication from a cyber security attack that infringes availability represented by a DoS attack from an extra-vehicle network. Included are: an external-network-side transfer processing unit that transfers a communication frame received from an external network to an internal network; an internal-network-side transfer processing unit that transfers the communication frame transferred from the external network via the external-network-side transfer processing unit to the internal network; a transfer notification unit that gives a transfer notification to notify transfer of the communication frame from the external-network-side transfer processing unit to the internal-network-side transfer processing unit; and a monitoring unit that determines whether to transfer the communication frame based on at least one of a frequency of the transfer notification to the internal-network-side transfer processing unit and a transfer data amount of the communication frame transferred from the external-network-side transfer processing unit.

Abstract: An object is to shorten a time required for reprogramming of a control device including a single-bank microcomputer. An ECU 901 is a control device including a first microcomputer 1 and a second microcomputer 2 that execute a program stored in a rewriting area 13 in which a memory bank is configured as a single bank. The second microcomputer 2 includes a preprocessing unit 214 that performs preprocessing on a rewriting program 5 in reprogramming processing of rewriting the program stored in the rewriting area 13 into the rewriting program 5, and a transmission unit 213 that transmits the preprocessed rewriting program 5 to the first microcomputer 1. The first microcomputer 1 includes a reception unit 121 that receives the rewriting program 5 transmitted from the second microcomputer 2, and a writing unit 122 that writes the received rewriting program 5 in the rewriting area 13.

Abstract: An object of the present invention is to minimize a likelihood of the vehicle becoming in an inoperable state even in an event of a program update failure. An in-vehicle device 6 includes: a program storage unit 64 that stores a program; an activation processing unit 65 that activates the program; and an update processing unit 63 that receives an update program 21 and an update reason 22 of the program and updates the program with the update program 21. In a case where the update of the program has failed, the activation processing unit 65 activates the program in an activation mode corresponding to the update reason 22.
