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.

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 displacing the opening and closing portion when the user applies a force to the opening and closing portion; a state detection unit configured to detect, based on an opening degree of the opening and closing portion, whether the opening and closing portion is in a small opening degree state in which the opening and closing portion has a first opening degree or less, or in an intermediate holding state in which the opening and closing portion is held at a second opening degree larger than the first opening degree; an obstacle detection unit configured to detect a distance from the opening and closing portion to an obstacle present in an area in an opening direction of the opening and closing portion; and a drive control unit configured to control the drive unit to reduce or increase an operation force of the user required for the manual operation based on a detection result of the manual operation detection unit, a detection result of the state detection unit, and a detection result of the obstacle detection unit. When the user performs an opening operation of opening the opening and closing portion in the small opening degree state and the obstacle is present within a predetermined distance from the opening and closing portion, the drive control unit controls the drive unit to generate a first braking force for increasing the operation force required for the opening operation, and when the user performs a first additional opening operation of further opening the opening and closing portion in the intermediate holding state, the drive control unit controls the drive unit to generate a second braking force that is a force for increasing the operation force required for the first additional opening operation and is smaller than the first braking force.

Abstract: A vehicle door lock device includes: a first member moving from an initial position to an actuated position so as to switch a latch mechanism, from a latched state to an unlatched state; a second member moving between a mechanical link position and a mechanical link cut position; a third member linked to the second member and holding the second member at the mechanical link cut position and holding the second member at the mechanical link position; a driving force source selectively moving the third member to one of the first and second positions; an operating member moving from an initial position to an actuated position, and moving the third member from the first position to the second position; and a control unit driving the driving force source. The control unit drives the driving force source to move the third member from the first position to the second position.
