Abstract
Methods and systems for detection and/or estimation of a rate of an occupant vital sign from within a cabin of a vehicle. In some implementations, the method may comprise identifying a repeating pattern of Doppler spectrum peaks in RADAR signal using a plurality of different range bins. An estimated frequency distance between adjacent peaks of the repeating pattern may then be identified using the signal data. An estimated rate of a repeating vital sign of an occupant within the cabin of the vehicle may then be calculated using the estimated frequency distance.

A method for detection of an occupant vital sign from within a cabin of a vehicle using RADAR, the method comprising the steps of:
- identifying a repeating pattern of Doppler spectrum peaks in RADAR signal over a plurality of different range bins;
- identifying an estimated frequency distance between adjacent peaks of the repeating pattern;
- and
- calculating an estimated rate of a repeating vital sign of an occupant within the cabin of the vehicle using the estimated frequency distance.
A method for detection of an occupant vital sign from within a cabin of a vehicle, the method comprising the steps of:
- transmitting one or more electromagnetic signals within a cabin of a vehicle;
- processing signals associated with the one or more electromagnetic signals;
- identifying a signal repetition frequency from the signals associated with the one or more electromagnetic signals, wherein the signal repetition frequency is indicative of a vital sign of an occupant within the cabin of the vehicle;
- and
- estimating a vital sign of the occupant using the signal repetition frequency.
A system for in-cabin detection of occupant vital signs using electromagnetic signal processing, comprising:
- an electromagnetic sensor positioned within a cabin of a vehicle;
- a detection module configured to process reflected electromagnetic signals into a plurality of range bins;
- and
- a vital sign module configured to use a signal repetition frequency associated with one or more of the range bins and estimate a rate associated with a vital sign of an occupant within the cabin of the vehicle.
