Abstract
Modulation and cutoff system for automotive interior fans/blowers which cuts off fan or closes shutters to stop or divert airflow during preselected Automotive Occupancy Sensor system operations so that the airflow does not interfere with, cause anomalies or short duration signal ambiguities in the US and IR sensor signal detection. The US sensor increases to a fast mode cycle upon receiving a crash imminent (CI) signal or upon detection of a Keep-Out Zone Intrusion (KOZI). Upon receipt of a CI or KOZI signal the fan/blower power is interrupted, slowed or the airstream is diverted. Alternately or additionally, the AOS system can be recalibrated for fan or air stream relative movement, the before/after fan interrupt US/IR signals can be compared, and a 'fan-on' signal can be used to change AOS fusion processing coefficient, feature selections or matrix.
