<p>A collision avoidance system includes an object detection module (50) mounted on a vehicle (54) for detecting the presence of an object (68) within a monitored zone of space (56) adjacent the vehicle (54). The detection unit (50) emits a plurality of beams (66) of infrared energy and detects the reflection of such energy from objects (68) within the zone. The detection module (50) is typically activated by the host vehicle's electrical turn signal. The detection module (50) includes a plurality of associated pairs of light emitting diodes (134) and photosensitive detectors (128) for sensing the reflected light.</p> |
