COLLISION DETECTION APPARATUS

摘要

A first linear arithmetic processor (4) integrates and processes an output value of a first acceleration sensor (11), and a first clip processor (6) extracts a component (V1) that is greater than a clip threshold value (0). A second linear arithmetic processor (5) integrates and processes an output value of a second acceleration processor (12), and a second clip processor (7) extracts a component (V2) that is greater than the clip threshold value. A differential arithmetic unit (8) calculates the differential value of V1 and V2, a threshold value comparator (9) determines that a vehicle has undergone a collision when the differential value is greater than a collision determination threshold value, and a drive circuit (10) for occupant protection devices causes first and second occupant protection devices (13, 14) to operate.
