Abstract
A vehicle behavior judgment system comprising a rolling angular velocity detector adapted for detecting a rolling angular velocity of a vehicle, a rollover judgment device adapted for judging, based on at least a rolling angular velocity of a vehicle, whether the vehicle rolls over or not, and a noise-cutting filter adapted for removing a noise component from the rolling angular velocity.
Claims11
A vehicle behavior judgment system comprising:
- a rolling angular velocity detector adapted for detecting rolling angular velocities in a time series of a vehicle,
- a rollover judgment device adapted for judging, based on at least one rolling angular velocity of the vehicle detected by the rolling angular velocity detector, whether the vehicle rolls over or not, and
- a noise-cutting filter adapted for removing a noise component from the rolling angular velocities,
- wherein, if a difference between a newest rolling angular velocity and a just previous rolling angular velocity as viewed in the time series exceeds a threshold value, the rollover judgment device is configured to replace the newest rolling angular velocity with the just previous rolling angular velocity and then to effect judgment as to “rollover” of the vehicle by using the just previous rolling angular velocity instead of the newest rolling angular velocity.

A vehicle occupant-protecting system comprising:
- a vehicle behavior judgment system, wherein the vehicle behavior judgment system comprises:
- a rolling angular velocity detector adapted for detecting rolling angular velocities in a time series of a vehicle,
- a rollover judgment device adapted for judging, based on at least one rolling angular velocity of the vehicle detected by the rolling angular velocity detector, whether the vehicle rolls over or not, and
- a noise-cutting filter adapted for removing a noise component from the rolling angular velocities,
- wherein, if a difference between a newest rolling angular velocity and a just previous rolling angular velocity as viewed in the time series exceeds a threshold value, the rollover judgment device is configured to replace the newest rolling angular velocity with the just previous rolling angular velocity and then to effect judgment as to “rollover” of the vehicle by using the just previous rolling angular velocity instead of the newest rolling angular velocity, and
- an occupant-protecting device which protects an occupant through an operation corresponding to a judgment result as to “rollover” obtained by the vehicle behavior judgment system.
