Abstract: A frame is divided, and is then transferred on a communication protocol having a different frame size. Provided is a vehicle control device configured to transfer data through a first communication path for transferring data having a low priority and a second communication path for transferring data having a high priority, the second communication path having a transfer speed different from that of the first communication path. First transfer data transferable on the first communication path has a data size different from that of second transfer data transferrable on the second communication path. The second communication path allows at least two types of transfer data to be transmitted and received thereon. When the first transfer data is divided and is then transferred on the second communication path, the data is transferred by controlling at least one of a division size, the number of divisions, or a transfer timing of the first transfer data based on a timing cycle for transferring the second transfer data, a vacant time having no transfer, and a transfer time of the first transfer data on the second communication path.
