Abstract
The method and system of this invention discriminates between a lateral collision and a static non-collision event by measuring lateral velocity of the vehicle and adjusting a threshold value causing occupant restraint system actuation according to the measured lateral velocity. The threshold value is decreased in response to an increase in lateral velocity and increased or maintained at a higher value when lateral velocity is minimal to prevent actuation caused by a non-crash event such as a door slam.
Claims15
A method of discerning a lateral impact of a vehicle comprising the steps of:
- a) measuring a lateral velocity;
- and
- b) lowering a deployment threshold value responsive to a measured lateral velocity indicative of lateral movement of the vehicle.
A system for verifying plausibility of a sensor measurement comprising:
- a lateral movement sensor for measuring lateral velocity;
- at least one other sensor measuring a characteristic indicative of a lateral collision, wherein a lateral collision is determined to be plausible responsive to the lateral movement sensor measuring lateral velocity above a threshold value.
