Patent Searching and Data


Title:
車両用衝突判定装置
Document Type and Number:
Japanese Patent JP4864242
Kind Code:
B2
Abstract:
A discrimination is made between a soft crashing in which a relatively low acceleration signal continues for a long period of time and a low-speed head-on crashing so that an air bag can be started at an appropriate timing. An occupant protecting apparatus for that purpose is made up of: a first comparator for comparing an output signal of an acceleration sensor which detects an impact at the time of crashing of a vehicle and a first threshold value; a second comparator for comparing an integrated value of an integrator which integrates an output of the first comparator within a predetermined section and a second threshold value while making a shift by a unit time within a predetermined section; and a starting device for controlling the starting of the air bag based on an output signal of the second comparator.
