Abstract: Method for processing a presence signal in a hands-free vehicle access system having capacitive sensors. After starting steps constituted by nominal operation, switching to low-energy consumption mode, and switching to polling of an interrogation signal at nominal frequency, this method includes: presence testing with nominal polling; requesting the identity of the electronic key, transmitted via a central unit; detecting the presence of a hand on a handle transmitted via a capacitive sensor to the central unit; and authorizing the unlocking of the vehicle. The method includes a step of reducing the frequency of signals transmitted by the antenna of the central unit so as to switch into a “slow polling” test, such that the capacitive sensors have sufficient time intervals to test the central unit for the presence of a hand during the information step. The capacitive sensors then have greater availability to signal the presence of a hand.

Abstract: This process comprises the following steps: detection of the need for resynchronization, identification of a desynchronized badge and memorization in a computer of a corresponding code, memorization of the message sent by the computer to the badges, and emission of the modified message (step 70), reception of the modified message by the desynchronized remote control, automatic resynchronization between the remote control and the computer, and emission of a response to the message from the computer, reception of the response from the badge by the computer, and erasure of the memory and return to the base message.

Abstract: This process relates to a remote control with a changing code used with a hands free system comprising a badge, a computer, emitting and receiving means, each badge including a remote control with a changing code.
