To achieve a favorable operation feeling relating to opening and closing of a door with a simple device configuration.SOLUTION: A door open-close auxiliary device 10 comprises: an information acquisition unit 33 for acquiring information on a speed Vdr of opening and closing a door 14; a door actuator 19 for performing drive for assisting an opening and closing operation of the door 14; a target auxiliary force calculation unit 37 for calculating a target auxiliary force Ptg to assist the opening and closing operation of the door 14; and a control unit 39 for controlling the drive relating to the door actuator 19 on the basis of the target auxiliary force Ptg. The target auxiliary force calculation unit 37 calculates a model auxiliary force Psd, which is an auxiliary force required to maintain the opening and closing speed Vdr, on the basis of the speed Vdr of opening and closing the door 14 that is acquired by the information acquisition unit 33, and performs correction of decreasing the calculated model auxiliary force Psd in accordance with a prescribed rule. The model auxiliary force Psd after the decreasing correction is regarded as the target auxiliary force Ptg.SELECTED DRAWING: Figure 2

    【課題】ドアの開閉に係る良好な操作感を簡素な装置構成によって実現する。【解決手段】ドア開閉補助装置10は、ドア14の開閉速度Vdrの情報を取得する情報取得部33と、ドア14の開閉操作を補助するための駆動を行うドアアクチュエータ19と、ドア14の開閉操作を補助するための目標補助力Ptgの演算を行う目標補助力演算部37と、目標補助力Ptgに基づいてドアアクチュエータ19に係る駆動制御を行う制御部39と、を備える。目標補助力演算部37は、情報取得部33が取得したドア14の開閉速度Vdrに基づいて、開閉速度Vdrを保つために要する補助力である規範補助力Psdを算出し、算出した規範補助力Psdを所定の規則に従い減少する補正を行い、減少補正後の規範補助力Psdを目標補助力Ptgとする。【選択図】図2
