A data processing apparatus (40), which operates by being supplied with power from an in-vehicle apparatus (10), and which performs predetermined data processing, is provided with: nonvolatile memory (46) for storing backup data to be held when power supply from the in-vehicle apparatus is stopped; prediction means (60, S210, S310, S410) that predict that the power supply from the in-vehicle apparatus is to be interrupted; and first backup means (60, S220-240, S320-340, S420-440) that store the backup data in the nonvolatile memory when the interruption of the power supply is predicted. |
