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.

摘要： Load sensors are disposed on four corners of a seat cushion. An occupant decision section of an occupant detection ECU decides a type of an occupant on a vehicle seat based on loads detected by the load sensors. A CRS changing section that prohibits the occupant decision section from changing a decision to a decision result that an adult is seated in the vehicle seat and changes the decision to a decision result that a child seat is attached on the vehicle seat when an engagement of a tongue plate with a buckle of a seat belt device is detected by a buckle switch and a buckle load calculated by buckle load calculation section is less than a predetermined buckling load threshold in a case where the occupant decision section decides that an adult is seated in the vehicle seat.

摘要： A vehicular occupant determination apparatus includes a load detection portion, an occupant determination portion, an acceleration detection portion, a transition prohibition portion, a drive state detection portion, and a prohibition release portion. The load detection portion detects a load of a left part or a right part. The occupant determination portion determines occupant types, and maintains or transits a determination result. The transition prohibition portion sets a transition prohibition state when the acceleration is equal to or greater than a predetermined acceleration threshold. The prohibition release portion sets a prohibition release state when (i) the acceleration is equal to or greater than the acceleration threshold, and (ii) the prohibition release portion detects that the vehicle is in stop based on a detection value detected by the drive state detection portion, the transition prohibition state being released during the prohibition release state.

摘要： A load sensor detects a load of an occupant on a seat of a vehicle and provides a load signal. A determination section determines a physical size of the occupant by classifying the load signal into a subject class among a plurality of classes ordered from small to large based on threshold loads and performs an inter-class transition of the subject class from a transition source class into a transition destination class based on change of the received load signal. When (i) both the transition source class and the transition destination class belong to an airbag-inflating class that enables inflating of an airbag, and, simultaneously, (ii) the transition destination class is smaller than the transition source class and immediately adjacent to the transition source class, the determination section makes the determined class remain in the transition source class.

摘要： An occupant determination apparatus includes a load sensor and a determination section. The load sensor detects a load of an occupant seated in a seat of a vehicle to provide the detected load as a load signal. The determination section determines presence or absence of the occupant and a physical size of the occupant by classifying the load signal into a subject class among a plurality of classes that are ordered from small to large according to the physical sizes based on predetermined threshold loads. The subject class is stored as a determined class. The determination section permits the determined class to transition from a present class to an immediately adjacent larger class when the load signal equal to or larger than a threshold load between the present class and the immediately adjacent larger class continues being received for a threshold time.

摘要： An occupant determination apparatus includes a weight sensor that senses a weight of an object on a seat of a vehicle, a lateral acceleration sensor that senses lateral acceleration of the vehicle, and a processing unit that performs an operation of occupant determination. The processing unit calculates a lateral acceleration difference that is an absolute value of a difference between first lateral acceleration at a time when the weight passes through a first load threshold value and second lateral acceleration at a time when the weight passes through a second load threshold value. The processing unit performs the occupant determination based on an occupant determination threshold value when the lateral acceleration difference is smaller than a lateral acceleration difference threshold value, and does not perform the occupant determination when the lateral acceleration difference is larger than the lateral acceleration difference threshold value.
