ABSTRACT:
A supplemental inflatable restraint system has a deployment algorithm which is enabled when a threshold acceleration is reached and then, based on subsequent measured acceleration data, determines whether and when to deploy an air bag. Rough road conditions produce accelerations which can enable the algorithm and then produce a reset event to terminate the algorithm. Reset events are each stored for a short time and the number of unexpired reset events is a measure of the rough road condition. The deployment calculation is adjusted to delay deployment for a time proportional to the number of reset events to allow gathering of additional acceleration data for the deployment decision.
