ABSTRACT:
An object presence detection device, of the type mounted to a motor vehicle having at least one blind spot, where the detection device is for detecting an object situated in the blind spot, comprises: a receiver for detecting electromagnetic waves, comprising a focussing device, and a light detector converting said received electromagnetic waves into electrical signals; an electronic circuit converting the electrical signals into digitized signals; a logic circuit analyzing the digitized signals to analyze the presence of objects in the blind spot which are moving relative to the vehicle, and emitting variable output signals depending on the result of the analysis; indicator members activated by the output signals, suitable to be perceived by the driver.
