PROBLEM TO BE SOLVED: To provide a controller of vehicle drive unit capable of continuously writing data which is frequently written without setting a new storing area on a non-volatile memory in which writing frequency is preset.SOLUTION: In a series of count processing, when the recorded number of times reaches the number of update times which is preset based on the number of writing available times, which is preset in a DF memory 12, when a power OFF operation of a vehicle is made during executing a series of data writing processing, a CPU 11 updates a first piece of data in a second area including a part in which a piece of second data is stored in the second area. When determining that a failure has occurred in a series of failure determination processing, the CPU 11 updates a first area including a part which stores the first data in the first area with the second data.SELECTED DRAWING: Figure 1

    【課題】書込み対応回数が設定された不揮発性メモリに新たな記憶領域を設けることなく書込み頻度の高いデータを継続して書き込み可能な車両用駆動装置の制御装置を提供する。【解決手段】CPU11は、カウント処理において記録した回数がDFメモリ12に設定されている書込み対応回数に基づいて設定された入換え回数に到達した場合、データ書込み処理の実行時において、車両の電源OFF操作が実行された場合に第2領域のうち第2データが記憶されている部分を含む第2領域に第1データを書き込み、故障判定処理において故障したと判定した場合に、第1領域のうち第1データが記憶されている部分を含む第1領域に第2データを書き込む。【選択図】図1
