A method for estimating the distance between a vehicle and an authentication device, the vehicle including a computer and a plurality of communication modules capable of communicating with the device over a wireless communication link, each communication module including an electronic clock that defines the sampling frequency of the signals received from the device. The method includes in particular the steps of addition of noise to a response signal received from the device, of sampling of the noisy response signal, of detection, at a second instant, of the noisy response signal when the amplitude of the noisy response signal exceeds a predetermined detection threshold, of calculation of the time that has elapsed between a first instant and the second instant, and of estimation of the distance between the vehicle and the device based on the calculated time.
A method for estimating the distance between a vehicle and an authentication device, said vehicle comprising a computer and a plurality of communication modules each capable of communicating with said device over a wireless communication link, each communication module comprising an electronic clock that defines the sampling frequency of the signals received from the device, said method comprising:
A communication module for a vehicle, said communication module being capable of communicating with a device for authenticating a user of said vehicle over a wireless communication link, each communication module comprising an electronic clock that defines the sampling frequency of the signals received from the device, the communication module being configured so as to:
