PROBLEM TO BE SOLVED: To define a high-reliability device as an information storage destination while suppressing cost as further as possible in an on-vehicle system.SOLUTION: A relay device receiving a memory bank request from a memoryless control device in which write request data are generated, selects, as a write destination candidate, one control device with a storage function to which a safety request level equal to a request source level is allocated and which includes a storage section in which free capacity more than a data size of the write request data is present, from among control devices with storage functions (S220). A write request is outputted to the selected write destination candidate (S260). If a response from the write destination candidate acquiring the write request indicates that the write request data can be written (S270:YES), the write destination candidate is identified as a write destination device and the write request data are outputted (S280). Thus, the write request data are written and stored in the storage section of the write destination device. |
