Title:
ROLL OVER JUDGMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/141936
Kind Code:
A1
Abstract:
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 ω in the rollover direction of the vehicle measured by an angular speed sensor (1) is regulated at a ω regulating section (3c). An angular component θo is calculated by performing time integration on the regulated angular speed component ωo in an integrator (3d). Based on the angular component θo and the measured angular speed component ω, 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).
