[Problem] To accurately obtain learning values of control parameters even if a power on/off operation is repeated. [Solution] An electronic control device (1) has a flash memory (12) that stores therein learning values of control parameters. The flash memory (12) has a plurality of blocks (31) and (32). When there is no residual storage capacity to be used in the first block (31) at the time of power on, it is checked if there is a set of learning values in the block (31). When a set of learning values is prepared completely in the second block (32), new learning values are written in the next block. On the other hand, when a set of learning values is not available in the second block (32), data in the second block (32) is erased, and then new learning values are written in the second block (32). |
