FUEL SUPPLY DEVICE OF ENGINE-MOUNTED BODY

PROBLEM TO BE SOLVED: To provide a fuel supply device of an engine-mounted body which can perform the feedback control of a drive current of an electric motor which copes with an individual difference and a secular change of a fuel pump without increasing a cost.SOLUTION: A current control part 102d1 controls a current which is conducted to a motor part 101b for a prescribed time T after an ECU 102 is activated so as to be brought into a stationary state, a current detection part 102c detects a current in the stationary state within the prescribed time T, a voltage detection part 102b detects a voltage in the stationary state within the prescribed time T, a target current calculation part 102d2 calculates a target current which is conducted to the motor part 101b on the basis of the current and the voltage which are detected within the prescribed time T, and the current control part 102d1 starts the feedback control of the current which is conducted to the motor part 101b so that the current which is conducted to the motor part 101b approximates the target current which is calculated at the target current detection part 102d2 after the lapse of the prescribed time T. 【課題】コストを増加させることなく、燃料ポンプの個体差や経時変化に対処した電動モータの駆動電流のフィードバック制御を行うことが可能なエンジン搭載体の燃料供給装置を提供する。【解決手段】電流制御部１０２ｄ１が、ＥＣＵ１０２を起動したときから所定時間Ｔ継続してモータ部１０１ｂに通電される電流を定常状態となるように制御し、電流検出部１０２ｃが、所定時間Ｔ内にその定常状態の電流を検出し、電圧検出部１０２ｂが、所定時間Ｔ内にその定常状態の電圧を検出し、目標電流算出部１０２ｄ２が、所定時間Ｔ内に検出された電流と電圧とに基づいて、モータ部１０１ｂに通電される目標電流を算出し、更に、電流制御部１０２ｄ１が、所定時間Ｔが経過した後、モータ部１０１ｂに通電される電流が目標電流算出部１０２ｄ２で算出された目標電流に近づくようにモータ部１０１ｂに通電される電流のフィードバック制御を開始する。【選択図】図１
