    Abstract: A method for activating a function of a motor vehicle by an activation device on the vehicle having at least one communication unit including at least one radiofrequency antenna and transmission and reception device. The activation coming from a user's portable device. The activation of the function is triggered by detection of the user's presence in a predetermined zone around the vehicle and on the basis of a result of authentication of the portable device by the vehicle. For at least two responses received from the portable device: a) comparing, for each response, a power of a first wave received at a time with a maximum power of the components of the first wave received, b) determining, for each response, a presence or absence of reflected waves, c) determining an averaged reflection rate for the responses, d) determining a minimum value for the time from the responses, e) if the averaged reflection rate is zero or full, then the user's presence in the predetermined area is determined using the minimum value for the time, f) if the averaged reflection rate is partial, then the user's presence in the predetermined area is detected using the minimum value for the time, to which a corrective coefficient is applied.

    Abstract: A vehicle anti-theft device that is operable to inhibit the operation of a keyless vehicle module wherein the present invention includes a first mode and a second mode. The present invention includes a second controller wherein the second controller is installed in a suitable location within a vehicle. The second controller is electrically coupled to the wiring harness of the vehicle wherein a circuit portion thereof is utilized to supply direct current power to the second controller. A key fob is provided wherein the key fob is operably coupled to the second controller. The key fob includes a first switch and a second switch wherein the first switch and second switch transition the present invention between the first mode and second mode. In the first mode of the present invention the second controller inhibits direct current flow to the first controller and as such renders the keyless vehicle module inoperable.

    Abstract: Disclosed is a vehicle capable of performing digital key authentication more smoothly. The vehicle includes a reader provided to perform communication with a digital key through near field communication (NFC), and a controller configured to perform a preset function of the vehicle based on a success of a transaction with the digital key through the reader, wherein the reader operates in a first mode of detecting the presence of the digital key based on the success of the transaction, and does not start the transaction even when the digital key is detected while operating in the first mode.

    Abstract: A vehicle may include: an autonomous vehicle sensor configured to detect an object located around the vehicle; an ultra wide band (UWB) module configured to receive a UWB signal transmitted from a digital key; and a controller configured to be electrically connected to the UWB module. The controller is configured to obtain sensor-based positioning information of the object located around the vehicle based on sensor data obtained by the autonomous vehicle sensor, obtain UWB-based positioning information of the digital key based on the UWB signal received in the UWB module, determine a position of the digital key based on the sensor-based positioning information of the object and the UWB-based positioning information of the digital key, and control the vehicle based on the determined position of the digital key.
