Embodiment Construction
[0025]Referring to FIGS. 1-2, a first operational mode of a passive infra-red pedestrian avoidance system in accordance with the present invention is illustrated. As illustrated in FIG. 1, a vehicle 100 generally travels within a travel lane 102 on a roadway 104. The system, generally designated by reference numeral 10, comprises at least one forward-looking passive IR image sensor or sensor array, generally designated as reference numeral 106, mounted on the vehicle 100 and directed outwardly in front of the vehicle 100, as the vehicle 100 moves, so that the IR sensor(s) 106 can detect any stationary or moving object(s) 108 containing a human thermal profile in the vehicle's travel lane 102, or in the process of heading towards the vehicle's predicted pathway.
[0026]In preferred embodiments of the present invention, as generally illustrated in FIG. 1, a single, forward-looking IR sensor 106 is mounted on the vehicle 100, preferably on the front of the vehicle 100, and more preferabl...
