Abstract
An occupant detection system for detecting an occupant within a vehicle includes a sensor for sensing movement or acceleration of the vehicle, first and second processors and a decider. The sensor generates a sensor output. The first processor processes the sensor output in a first manner and generates a first output indicative of the possibility of the presence of an occupant within the vehicle. The second processor processes the sensor output in a second manner and generates a second output indicative of the possibility of the presence of an occupant within the vehicle. The decider processes the first and second outputs and determines whether the combination of the first and second outputs is indicative of an occupant in the vehicle.
Claims22
An occupant detection system for detecting an occupant within a vehicle, said occupant detection system comprising:
- a sensor for sensing movement within the vehicle, said sensor generating a sensor output;
- a first algorithmic processor for algorithmically processing said sensor output in a first algorithmic manner, said first algorithmic processor generating a first output indicative of the possibility of the presence of an occupant in the vehicle;
- a second algorithmic processor for algorithmically processing said sensor output in a second algorithmic manner, said second algorithmic processor generating a second output indicative of the possibility of the presence of an occupant in the vehicle;
- wherein said first algorithmic manner is different than said second algorithmic manner;
- and
- a decider that processes said first and second outputs and determines whether the combination of said first and second outputs is indicative of an occupant in the vehicle.
