Occupant determination apparatus
First Claim
Patent Images
1. An occupant determination apparatus comprising:
- a load sensor that measures a weight of an occupant seated on a seat of a vehicle as a measurement weight; and
a determinator determining the weight of the occupant as one status among a plurality of statuses which are set corresponding to the weight based on the measurement weight measured by the load sensor,wherein the determinator;
determines the weight of the occupant as an instantaneous status among the plurality of statuses, based on the measurement weight measured for each unit time;
invalidates a determination result of the instantaneous status when an acceleration acting on the vehicle exceeds a threshold acceleration set in advance; and
continues to invalidate the determination result of the instantaneous status for each unit time during a predetermined time after the acceleration acting on the vehicle changes from exceeding the threshold acceleration set in advance to not exceeding the threshold acceleration set in advance.

Abstract
An occupant determination apparatus includes a load sensor that detects weight of an occupant seated on a seat of a vehicle, and a determinator determining the weight of the occupant as one status among a plurality of statuses which is set corresponding to the weight based on the measurement weight measured by the load sensor. In a case where an absolute value of acceleration acting on the vehicle becomes equal to or larger than the threshold value set in advance, the determinator determines the weight of the occupant as one of the status among the plurality of statuses based on the measurement weight measured before it becomes the threshold value.
