Functional description

The GK2, as a passive entry vehicle key, is part of a driving authorisation system, which further consists of a Body Control Unit and up to 8 UWB vehicle modules.
The Body Control Unit in the vehicle initiates the communication to the GK2 over Bluetooth LE. After successful identification, a time-of-flight measurement is triggered bidirectionally between the UWB vehicle module and the GK2.
The distance is measured between the UWB vehicle module and the GK2 by means of the time of flight based on speed of light.
The components exchange encrypted data for car access, to start the engine and to locate the key.

User manual

GK2 and vehicle BNCM establish a connection and exchange data through BLE.
The distance measurement is a bidirectional communication between key and GU1. The key is called verifier and sends first to the GU1. The GU1 is called prover and sends back, after receiving the verifier signal. The key then computes the distance from the time of flight.
The Body Control Unit in the vehicle can automatically operate functions such as unlocking measurements depending on the distance of the key.
