Airbag apparatus
First Claim
1. An airbag apparatus comprising:
- a controller that conducts sampling of acceleration values output from a plurality of acceleration sensors disposed on a vehicle and controls inflation of an airbag based on the sampled acceleration values;
a prediction unit that predicts a collision direction in which collision with another vehicle would occur; and
a sampling-period control unit that, when the prediction unit predicts the collision direction, shortens a sampling period for the acceleration sensor disposed in the predicted collision direction in comparison with sampling period for the other acceleration sensors, wherein;
after the sampling-period control unit shortens the sampling period, the controller determines whether or not to inflate the airbag, based on the sampled acceleration values output from the acceleration sensor disposed in the predicted collision direction.

Abstract
An airbag apparatus includes a controller, a prediction unit, and a sampling-period control unit. The controller conducts sampling of acceleration values output from a plurality of acceleration sensors disposed on a vehicle and controls inflation of an airbag based on the sampled acceleration values. The prediction unit predicts a collision direction in which collision with another vehicle would occur. When the prediction unit predicts the collision direction, the sampling-period control unit shortens a sampling period for the acceleration sensor disposed in the predicted collision direction in comparison with sampling period for the other acceleration sensors. After the sampling-period control unit shortens the sampling period, the controller determines whether or not to inflate the airbag, based on the sampled acceleration values output from the acceleration sensor disposed in the predicted collision direction.

8. An airbag apparatus comprising:
-
a controller that conducts sampling of acceleration values output from a plurality of acceleration sensors disposed on a vehicle and controls inflation of an airbag based on the sampled acceleration values;
a prediction unit that predicts a collision direction in which collision with another vehicle would occur; and
a sampling-period control unit that, when the prediction unit predicts the collision direction, gives priority in the sampling of the acceleration values to the acceleration sensor disposed in the predicted collision direction, wherein;
after the sampling-period control unit gives the priority, the controller conducts the sampling of the acceleration values in accordance with the priority and determines whether or not to inflate the airbag, based on the sampled acceleration values output from the acceleration sensor to which the priority is given. - View Dependent Claims (9, 10, 11, 12, 13, 14, 18, 19, 20, 22, 24, 26)
