A system and method are provided for obtaining calibration data for a portable device relative to an object in order to facilitate defining a locator for determining a location of the portable device relative to the object. The system and method may obtain calibration data pertaining to a signal characteristic of communications transmitted from the portable device and corresponding to a known location of the portable device (e.g., truth data).

A system and method for a single use device for customer vehicle key programming. The device takes the form of a so-called dongle that plugs into the vehicle OBD. The customer uses an application on a smartphone to communicate with the vehicle through the dongle on one end and with the system servers on the other.

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.

A method for operating a motor vehicle having at least one vehicle communication arrangement fixed to the body. Signals are emitted by a user device, which can be handled independently of the motor vehicle and can be assigned or is assigned to a driver of the motor vehicle, and are received by the vehicle communication arrangement. A distance between the user device and the motor vehicle is monitored on the basis of the received signals. Provision is made for the distance to be monitored during operation of the motor vehicle and for a safety operating state of the motor vehicle to be activated when a distance exceeding a predefined threshold value is detected.
