Airbag device and vehicle
An airbag device includes: an airbag body that is configured to deploy toward a front side of a driver; and a control unit that is configured to deploy the airbag body using a first deployment method when a central axis of a rim portion of a steering member of a vehicle is in a first state and a deployment condition is satisfied and deploy the airbag body using a second deployment method in a second state when an inclination angle of the central axis in relation to the central axis in the first state exceeds a threshold and the deployment condition is satisfied.
1. An airbag device comprising:
an airbag body that is configured to deploy toward a front side of a driver; and
a control unit that is configured to deploy the airbag body using a first deployment method when a central axis of a rim portion of a steering member of a vehicle is in a first state and a deployment condition is satisfied and deploy the airbag body using a second deployment method in a second state when an inclination angle of the central axis in relation to the central axis in the first state exceeds a threshold and the deployment condition is satisfied, wherein
the airbag body includes a first airbag body and a second airbag body disposed inside the steering member,
the second airbag body is formed to be deployed in a direction different from a deployment direction of the first airbag body in relation to the rim portion, and
the control unit is configured to deploy the second airbag body when the inclination angle exceeds the threshold and the deployment condition is satisfied.
2. The airbag device according to claim 1 , wherein
the inclination angle is an angle about an axis extending in a vehicle width direction.
3. The airbag device according to claim 1 , wherein
the first airbag body is disposed inside a first member of the steering member, which is displaced integrally with the rim portion, and
the second airbag body is disposed inside a second member of the steering member, which supports the first member so as to be displaceable.
4. The airbag device according to claim 1 , wherein
the first airbag body and the second airbag body are disposed inside a member of the steering member, which is displaced integrally with the rim portion.
5. The airbag device according to claim 1 , wherein
the deployment of the first airbag body is inhibited when the inclination angle exceeds the threshold.
6. A vehicle comprising:
the airbag device according to claim 1 ;
an automated driving controller that is configured to execute driving assistance in a host vehicle; and
an inclination control unit that is configured to change the inclination angle according to a state of driving assistance executed by the automated driving controller.
