METHOD AND SYSTEM FOR UNATTENDED CHILD DETECTION
First Claim
1. A method for ascertaining whether an unattended child is present within an automotive vehicle using a radar sensor system, the radar sensor system comprising a transmitter, at least one sensor, and processing circuitry, the method comprising:
- illuminating, using the transmitter, at least one occupiable position within the vehicle with radiation, the radiation exhibiting at least one frequency;
generating, using at least one sensor, radar sensor signals from radiation reflected as a result of the transmitted radiation; and
carrying out, using the processing circuitry, the following steps;
generating, based on the radar sensor signals, a first indicator value, the first indicator value indicating a degree of motion associated with the occupiable position;
determining whether the first indicator value satisfies a first predetermined criteria;
when the first indicator value satisfies the first predetermined criteria, generating, based on radar sensor signals, a second indicator value, the second indicator value indicating a degree of repetitive pattern within the radar sensor signals; and
determining that an unattended child is present within the automotive vehicle if the second indicator value satisfies a second predetermined criteria.

Abstract
A radar sensor system and method for ascertaining whether an unattended child is present within an automotive vehicle. The radar sensor system carries out the method and includes a transmitter, at least one sensor, and processing circuitry. The method includes the steps of: illuminating at least one occupiable position within the vehicle with radiation of multiple frequencies; generating radar sensor signals from reflections of the transmitted radiation, a plurality of the radar sensor signals corresponding to different frequencies; and operating the processing circuitry for generating and determining if a first indicator value indicative of motion in the occupiable position satisfies a first predetermined criteria and, if so, generating and determining a second indicator value indicating a degree of repetitive pattern within the radar sensor signals, and determining presence of an unattended child in the vehicle if the second indicator value satisfies a second predetermined criteria.
