Abstract:
1. A detection device ( 4 ) for detecting the presence of an object in a proximity detection zone of a motor vehicle by measuring a variation in coupling capacitance brought about by the presence of said object, comprising: a first emission element ( a first reception element ( a detection zone proximate the first emission element ( a synchronous demodulation device that amplitude demodulates the modulated electric signal received by the first reception element ( a control electronics ( the first emission element ( a variation in the coupling capacitance between the first emission element ( establishment of a coupling capacitance between the first emission element ( an information device operatively connected to the measuring element, the information device configured to i) inform a vehicle's driver of the presence of a moving obstacle around the motor vehicle based on a signal from the measuring element, and ii) inform the driver of the presence of a stationary obstacle around the motor vehicle based on another signal from the measuring element; a second emission element ( the first and second emission elements ( the first emission element ( the first reception element ( the first reception element (
