First Claim
Patent Images
1. A collision determining apparatus for a vehicle comprising:
- a vibration detection device that detects a high-frequency vibration of an audio band generated in a vehicle and a low-frequency vibration of the audio band which is lower than the high-frequency vibration; and
a collision determining device that determines whether or not a collision requiring an activation of an occupant protection apparatus of the vehicle has occurred based on the detection result of the high-frequency vibration and the low-frequency vibration.

4. A collision determining apparatus for a vehicle comprising:
-
a vibration detection device that detects a broad-band vibration generated in a vehicle; a first extraction device that extracts a high-frequency vibration of an audio band from the broad-band vibration detected by the vibration detection device; a second extraction device that extracts a low-frequency vibration of the audio band which is lower than the high-frequency vibration from the broad-band vibration detected by the vibration detection device; and a collision determining device that determines whether or not a collision requiring an activation of an occupant protection apparatus of the vehicle has occurred based on the detection result of the high-frequency vibration and the low-frequency vibration. - View Dependent Claims (5, 9, 10, 11)
