System for detecting the presence of a user particularly for motor vehicle

A system for detecting the presence of a user external a motor vehicle opening panel comprising,

• a handle carried by the opening panel;
• a user presence sensor comprising a monitoring module, at least one measurement electrode and at least one reference electrode;
• said electrodes each being connected to the monitoring module and positioned at least in part at the level of the handle,
• electromagnetic coupling being established between said electrodes so as to define at least one user presence detection zone creating at least one zone of nondetection of presence of the user,
• the detection of the presence of the user at the level of said zone allowing the control of at least one given function at the level of the vehicle,
• wherein the system also comprises means for creating at least one zone of nondetection of presence of the user by local modification of the presence detection zone;
• wherein the means for creating said zone of nondetection of presence are formed by said electrodes which are brought locally close together so that the electromagnetic coupling which results therefrom increases, thereby giving rise locally to a drop in the sensitivity of detection of the presence sensor.

A system for detecting the presence of a user within an area defined by an area of a handle externally disposed on an opening panel of said motor vehicle,

• a single user presence sensor disposed within said area of said handle, said single user presence sensor including,
• a monitoring module,
• a single measurement electrode and
• a single reference electrode disposed proximate said measurement electrode, wherein
• said measurement electrode and reference electrode being connected to said monitoring module and positioned at least in part at the level of the handle,
• an electromagnetic coupling being established between said measurement electrode and said reference electrode so as to define at least one user presence detection zone and at least one zone of non detection of presence each being within said area, detection of the presence of the user within said user detection zone allowing the control of at least one given function, and
• a mechanism for creating said at lease one zone of non detection of presence of the user;
• wherein said single sensor creates two user presence detection zones separated by said zone of non-detection of presence of the user so as to allow the control of two distinct functions.

A system for detecting the presence of a user within an area defined by an area of a handle externally disposed on an opening panel of said motor vehicle,

• a single user presence sensor disposed within said area of said handle, said single user presence sensor including,
• a monitoring module,
• a single measurement electrode and
• a single reference electrode disposed proximate said measurement electrode, wherein
• said measurement electrode and reference electrode being connected to said monitoring module and positioned at least in part at the level of the handle,
• an electromagnetic coupling being established between said measurement electrode and said reference electrode so as to define at least one user presence detection zone and at least one zone of non detection of presence each being within said area, detection of the presence of the user within said user detection zone allowing the control of at least one given function, and
• a mechanism for creating said at lease one zone of non detection of presence of the user;
• and
• wherein said mechanism for forming said at least one zone of non-detection is formed by varying the distance between said measurement electrode and said reference electrode such that at least a portion of said electrodes are disposed in close proximity to one another such that the electromagnetic coupling which results therefrom increases thereby giving rise locally to a drop in the sensitivity of detection of the presence sensor.
