To suppress a requested torque for a motor in winding up a seat belt by driving force of the motor in order to prepare for multiple collisions, at the time of occurrence of a mild collision.SOLUTION: A winding-up device is configured to wind up a seatbelt into a spool by driving force of a motor. A seatbelt control ECU, when a collision in which deceleration G detected by a floor sensor is equal to or below a first threshold Gth1 occurs, makes the motor wind up the seatbelt, after the deceleration G decreases to equal to or below a second threshold Gth2 smaller than the first threshold Gth1 or after a prescribed time t1 during which the deceleration G is estimated to has decreased to equal to or below the second threshold Gth2 elapses.SELECTED DRAWING: Figure 5

    【課題】軽度の衝突が発生した際に多重衝突に備えてモータの駆動力でシートベルトを巻き取る場合の、モータに対する要求トルクを抑制する。【解決手段】巻取装置は、モータの駆動力でシートベルトをスプールに巻き取る構成である。シートベルト制御ECUは、フロアセンサによって検出された減速度Gが第1閾値Gth1以下の衝突が発生した場合に、減速度Gが第1閾値Gth1よりも小さい第2閾値Gth2以下に低下した後、又は、減速度Gが第2閾値Gth2以下に低下したと推定される所定時間t1が経過した後に、モータによってシートベルトを巻き取らせる。【選択図】図5
