To stop an opening/closing body in a smooth manner.SOLUTION: A door ECU has a function as an operation request detection unit for detecting an operation request of a slide door as an opening/closing body provided in a door opening of a vehicle. In addition, the door ECU also has a function as an opening/closing control unit for controlling the operation of the slide door by controlling a motor serving as a driving source of the door ECU based on the detected operation request. Further, the door ECU executes advance control for advancing the phase of a motor control signal. Further, the door ECU executes advance control for advancing the phase of the motor control signal. Then, if a stop request of the slide door is detected during the drive of the slide door accompanying the execution of the advance control, the door ECU stops the drive of the slide door by reducing drive power supplied to the motor and reducing the advance value α of the advance control.SELECTED DRAWING: Figure 7 【課題】開閉体を円滑に停止させること。【解決手段】ドアＥＣＵは、車両のドア開口部に設けられた開閉体としてのスライドドアの作動要求を検出する作動要求検出部としての機能を備える。また、ドアＥＣＵは、検出された作動要求に基づいて、その駆動源となるモータを制御することによりスライドドアの作動を制御する開閉制御部としての機能を備える。更に、ドアＥＣＵは、モータ制御信号の位相を進角させる進角制御を実行する。そして、ドアＥＣＵは、その進角制御の実行を伴うスライドドアの駆動中に、このスライドドアの停止要求が検出された場合には、モータに供給する駆動電力を低減するとともに進角制御の進角値αを低減することにより、そのスライドドアの駆動を停止する。【選択図】図７
