Abstract: An operation assistance system for assisting a user in operating an opening and closing portion includes: a sensor configured to detect an acceleration applied to the opening and closing portion; a drive unit configured to generate a driving force for displacing the opening and closing portion; a manual operation detection unit configured to detect, based on the acceleration detected by the sensor, a manual operation of opening or closing the opening and closing portion when the user applies a force to the opening and closing portion; and a drive control unit configured to control the drive unit to reduce an operation force of the user required for the manual operation when the manual operation is detected. The manual operation detection unit determines that the manual operation is performed when a difference value between the acceleration applied to the opening and closing portion and an average acceleration that is an average value of the accelerations in a predetermined period is equal to or larger than a first threshold.
