Activation control apparatus of occupant safety system
First Claim
1. An activation control apparatus of an occupant safety system comprising:
- a first sensor disposed at a predetermined position in a vehicle, for detecting a first detection value according to an impact on the vehicle;
activation control means of the occupant safety system for activating the occupant safety system when a first operation value obtained based on the first detection value detected by said first sensor exceeds a predetermined threshold;
a second sensor disposed more to the front than said first sensor in said vehicle, for detecting a second detection value of at least two different magnitudes according to a level of the impact on the vehicle; and
threshold changing means for decreasing said predetermined threshold by a change amount according to the second detection value of said second sensor, wherein said threshold changing means comprises threshold change amount increasing means for increasing the change amount of said predetermined threshold with increase in a second operation value obtained based on the second detection value detected by said second sensor.
