ROLL OVER JUDGMENT DEVICE

摘要

Based on the acceleration component of a vehicle in the right/left direction or the up/down direction measured by an acceleration sensor (2), magnitude of the angular speed component ? in the rollover direction of the vehicle measured by an angular speed sensor (1) is regulated at a ? regulating section (3c). An angular component ?o is calculated by performing time integration on the regulated angular speed component ?o in an integrator (3d). Based on the angular component ?o and the measured angular speed component ?, a judgment means (4) performs predetermined multiplication and addition; and if the addition results exceed a preset threshold (Th), a rollover judgment signal is delivered to an air bag controller (5).
