Method for multi-directional anticipatory arming of vehicle restraints
First Claim
1. A method for multi-directional anticipatory arming of restraint systems for a vehicle comprising the steps of:
- monitoring outputs from impact radar sensors located on the vehicle;
determining whether an impact range is less than a predetermined value;
obtaining a closing velocity (CV);
determining a supervisory time window (STW);
determining whether at least one of the CV and STW are within predetermined limits; and
setting a velocity arming flag to activation of the restraint systems if the CV and STW are within the predetermined limits.

Abstract
A method for multi-directional anticipatory arming of restraint systems in a motor vehicle includes the steps of monitoring outputs from impact radar sensors located on the vehicle. The method also includes the steps of determining whether an impact range is less than a predetermined value, obtaining a closing velocity (CV), and determining a supervisory time window (STW). The method further includes the steps of determining whether at least one of the CV and STW are within predetermined limits and setting a velocity arming flag to activation of the restraint systems if the CV and STW are within the predetermined limits.
