ABSTRACT:
A detecting device for a vehicle and method thereof is provided. The device includes a first infrared detector, a second infared detector, and a controller. The first infrared detector is configured to repeatedly measure a temperature of a first target area by receiving infrared radiation of the first target area over a sampling period. The second infrared detector is configured to repeatedly measure a temperature of a second target area by receiving infrared radiation of the second target area over the sampling period. The controller is configured to receive and store the plurality of first and second signals, wherein the controller repeatedly compares a plurality of correlation values to a predetermined tolerance range above a minimum threshold value, wherein the correlation values are determined by repeatedly comparing a plurality of time delayed signals of the second plurality of signals to a real time signal of the plurality of first signals.
