Claim of US Patent No. 10,688,949

1. An occupant protection device comprising:a first sensor for detecting a value concerning a rotation angle of a vehicle;
a second sensor provided on a side of the vehicle to detect an acceleration in a vehicle longitudinal direction; and
a collision determination controller configured to determine whether or not a collision has occurred to the vehicle based on detection result of the first sensor, the collision determination controller also determining whether or not the collision has occurred to the vehicle based on detection result of the second sensor,
wherein the value concerning the rotation angle of the vehicle includes a yaw rate of the vehicle, and
wherein the collision determination controller determines whether or not the collision has occurred to the vehicle based on the detection result of the first sensor for a collision at a first speed, and also determines whether or not the collision has occurred to the vehicle based on the detection result of the second sensor for a collision at a second speed faster than the first speed.
