Abstract: A method and device for filtering electromagnetic interference generated by the antenna of a transmitter on a sensor sensitive to electromagnetic waves, characterized in that it includes: vi. elements suitable for sampling the signal received by the sensor, vii. elements for count down the elapsed time, called the detection time, after the sampled signal has exceeded a threshold value, the signal, before exceeding the threshold value, being in a range of standard values, viii. elements for comparing in real time the detection time with a threshold time value, ix. elements suitable for providing a diagnosis of electromagnetic interference to be filtered if the sampled signal reverts to a standard value after a detection time of less than the threshold time value, and a diagnosis of an uninterfered sampled signal if this is not the case, x. elements for generating an output signal from the sensor eliminating the diagnosed electromagnetic interference.

Abstract: A device for hands-free access to a vehicle (V) includes a portable remote control unit (1) and a central processing unit (2) installed in the vehicle, each integrating transmission element (1a, 3) making it possible to implement procedures for authorizing access to the vehicle (V), and a switch (8-11) integrated into the handle (P) of at least one door and designed to switch from a passive to an active state when a user makes access to the handle. The central processing unit (2) is programmed to control the supply of an actuator (13) for unlocking the door immediately after validation of an access authorization procedure, and the switch (8-11) is electrically integrated into the circuit (6) for supplying this actuator (13) so as to keep this supply circuit open in the passive state of the switch.
