ELECTRIC PUMP CONTROL DEVICE

To provide an electric pump control device which can accurately drive an electric pump.SOLUTION: An electric pump control device 1 comprises: a first drive indication information acquisition section 10 for acquiring first drive indication information indicating a first drive indication for bringing an electric pump P into a first drive state from a control unit 2; a first storage section 20 for storing an on-DUTY ratio related to the first drive state in advance; a difference calculation section 30 for calculating a difference between an on-DUTY ratio related to the acquired first drive indication information and the on-DUTY ratio related to the first drive state which is stored in the first storage section 20; a second storage section 40 for storing the calculated difference; a second drive indication information acquisition section 50 for acquiring a drive indication to the electric pump P as second drive indication information from the control unit 2 on and after the storage of the difference; and a pump control section 70 for driving the electric pump P on the basis of the corrected on-DUTY ratio which is obtained by correcting the on-DUTY ratio related to the acquired second drive indication information on the basis of the difference.SELECTED DRAWING: Figure 1 【課題】電動ポンプを精度良く駆動することが可能な電動ポンプ制御装置を提供する。【解決手段】電動ポンプ制御装置１は、制御ユニット２から電動ポンプＰを第１駆動状態にさせる第１駆動指示を示す第１駆動指示情報を取得する第１駆動指示情報取得部１０と、第１駆動状態に係るオンＤＵＴＹ比を予め記憶しておく第１記憶部２０と、取得された第１駆動指示情報に係るオンＤＵＴＹ比と第１記憶部２０に記憶されている第１駆動状態に係るオンＤＵＴＹ比との差異を算定する差異算定部３０と、算定された差異を記憶する第２記憶部４０と、差異が記憶された以降において、制御ユニット２から電動ポンプＰに対する駆動指示を第２駆動指示情報として取得する第２駆動指示情報取得部５０と、取得された第２駆動指示情報に係るオンＤＵＴＹ比を差異に基づいて補正した補正済オンＤＵＴＹ比に基づいて電動ポンプＰを駆動するポンプ制御部７０とを備える。【選択図】図１
