VEHICULAR OCCUPANT DETERMINATION APPARATUS

摘要

A vehicular occupant determination apparatus includes a load detection portion, an occupant determination portion, an acceleration detection portion, a transition prohibition portion, and a transition permission portion. The transition permission portion detects whether an acceleration increases or decreases a load, and sets a transition permission state even during the transition prohibition state. In the transition permission state, a determination result of a first occupant type is permitted to transit to a determination result of a second occupant type with a smaller load than the load of the first occupant type when the acceleration increases the load, and the determination result of the first occupant type is permitted to transit to a determination result of a third occupant type with a greater load than the load of the first occupant type when the acceleration decreases the load.

主权项

1. A vehicular occupant determination apparatus comprising:
a load detection portion that detects a load of either a left part or a right part of a seat portion of a vehicle seat in a vehicle; an occupant determination portion that determines any one of occupant types on the vehicle seat based on the load detected by the load detection portion, and maintains or transits a determination result of the occupant types; an acceleration detection portion that detects an acceleration in a width direction of the vehicle; a transition prohibition portion that sets a transition prohibition state when the acceleration is equal to or greater than a predetermined acceleration threshold, wherein the determination result of the occupant types is prohibited to transit in the transition prohibition state; and a transition permission portion that
detects whether the acceleration increases or decreases the load, andsets a transition permission state even during the transition prohibition state, wherein in the transition permission state, the determination result of a first occupant type is permitted to transit to the determination result of a second occupant type with a smaller load than the load of the first occupant type when the acceleration increases the load, and the determination result of the first occupant type is permitted to transit to the determination result of a third occupant type with a greater load than the load of the first occupant type when the acceleration decreases the load, the occupant types include the first occupant type, the second occupant type, and the third occupant type.
