Abstract
A crash determination device employed in a vehicle side impact passenger protection system uses logic circuits or microcomputers to correctly determine whether an impact is a crash with an obstruction such as another vehicle by making use of a phase difference between detected accelerations of a side acceleration sensor and a central acceleration sensor. By making use of the phase difference between detected accelerations of side and center acceleration sensors, a high-speed crash can be correctly distinguished from a low-speed impact and an erroneous determination resulting in the passenger protection system being operated in a side impact situation not necessitating operation of the passenger protection system can be avoided.
