In the embodiment, in the case where confirming that vehicle collides, then a possibility that driver is injured is judged, therefore,
Keep testing result more accurate, does not detect the motion state of driver then when confirming vehicle there is no colliding, thus keep away
Exempt from unnecessary detection and data processing, reduces data processing amount.
A variety of methods can be used by judging whether vehicle collides.For example, the driving status when vehicle meets in following
One of or when more persons, instruction vehicle collides: the numerical value for generating the acceleration of collision alarm, vehicle in direction of retreat is big
It is greater than scheduled third acceleration rate threshold in the numerical value of scheduled second acceleration rate threshold, the side acceleration of vehicle.
Collision alarm can be by obtaining with the crash sensor in airbag apparatus, and crash sensor can detecte vehicle
Impact strength, and collision alarm is generated when detected impact strength is greater than predetermined threshold.Second acceleration rate threshold and
Three acceleration rate thresholds can be obtained by test or experience.The numerical value of acceleration of the vehicle in direction of retreat is greater than scheduled the
Two acceleration rate thresholds show vehicle by collision backward and impact strength it is larger, the numerical value of the side acceleration of vehicle is greater than pre-
Fixed third acceleration rate threshold show vehicle by lateral collision and impact strength it is larger.
