Vehicular occupant motion detection system using radar
First Claim
1. A vehicle including a system for determining occupancy of the vehicle, comprising:
- a radar system for emitting radio waves into an interior of the vehicle in which objects might be situated and receiving radio waves; and
a processor coupled to said radar system for determining the presence of any repetitive motions indicative of a living occupant in the vehicle based on the radio waves received by said radar system such that the presence of living occupants in the vehicle is ascertainable upon the determination of the presence of repetitive motions indicative of a living occupant.

Abstract
System and method for determining occupancy of a vehicle in which a radar system emits radio waves into an interior of the vehicle in which objects might be situated and receives radio waves and a processor coupled to the radar system determines the presence of any repetitive motions indicative of a living occupant in the vehicle based on the received radio waves such that the presence of living occupants in the vehicle is ascertainable upon the determination of the presence of repetitive motions indicative of a living occupant. Repetitive motions indicative of a living occupant may be a heart beat or breathing as reflected by movement of the chest. The processor may be programmed to analyze the frequency of the repetitive motions based on the received radio waves whereby a frequency in a predetermined range is indicative of a heartbeat or breathing.

14. A method for determining occupancy of the vehicle, comprising the steps of:
-
emitting radio waves into an interior of the vehicle in which objects might be situated;
receiving radio waves after interaction with any objects; and
determining the presence of any repetitive motions indicative of a living occupant in the vehicle based on the received radio waves such that the presence of living occupants in the vehicle is ascertainable upon the determination of the presence of repetitive motions indicative of a living occupant. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
