  • a load detecting portion which is disposed on a lower side of a seat of the vehicle and which detects a load that acts on the seat;

    an occupant discrimination portion which discriminates a state of an occupant who is seated on the seat among a no occupant state, an adult seated state, and a child seat fixed state based on a state transition condition on the basis of a load which is detected from the load detecting portion and a load continuation duration; and

    a door opening and closing state detecting portion which detects an opening and closing state of a door of the vehicle,wherein the occupant discrimination portion sets a first continuation duration which is a state transition condition for transitioning from the no occupant state or the child seat fixed state to the adult seated state in a state in which the door opening and closing detecting portion detects the door open state to be longer than a second continuation duration which is a state transition condition for transitioning from the no occupant state or the child seat fixed state to the adult seated state in a state in which the door opening and closing detecting portion detects the door closed state.
