Patent ID: 7378947

Claim:
An active monitoring device within a safety perimeter of a motor vehicle, for the detection of moving objects or static obstacles within said safety perimeter, comprising: a first detector which has a first detection angle and a first radius of action, which covers a first detection zone that includes at least part of a blind angle of said vehicle, where said first detector transmits input signals to at least one data processing device that generates output signals suitable to activate warning means for the driver; at least a second detector, which has a second detection angle and a second radius of action, which covers a second detection zone and forms, with said first detector, a group, with said first and at least one second detectors cooperate in order to cover a combined detection zone of said blind angle, which is enlarged with respect to that covered by the first detector and which forms a sector of said safety perimeter; said first and at least one second detectors of said group share the same warning means that can be activated via the processing of the output signals from each one; and at least one of said detectors is an optical camera capable of operation in the visible and/or infrared spectra, wherein each of the cited detectors can be activated or not or perform differential processing on the captured information as a function of the vehicle's speed.
