Page 4 / 8 1 SYSTEM OVERVIEW 1.1 Scope of Document The aim of this document is to provide a short overview on the HFM_CMFB_01 Hand free system. 1.2 Short Description of the complete System including HFM_CMFB_01 The HFM_CMFB_01 is a radio frequency transmitter-receiver used in vehicle access systems. The vehicle access system includes:  Key fob, which is a remote device It includes a 315 MHz or 433.92 MHz transmitter, a 125 kHz LF receiver and a 125 kHz transponder  LF Antennae  Kazashi includes a coil antenna for 125 kHz transponder communication  HFM (Hand Free Module) of model HFM_CMFB_01: It includes a 125 kHz LF long range and transponder transmitters and a 315 MHz or 433.92 MHz receiver. The HFM_CMFB_01 drives 5 external dedicated antennae for the 125 kHz transmission. Two are located in the doors trims, one in the Bumper and two within the vehicle cockpit. It includes also an integrated RF receiver for 315 MHz or 433.92 MHz, the receiver is designed in direct placement. The system interacts with other modules such as:  Push Engine Start  Body Control Module  ESCL (Electronic Steering Lock Control)  USM The main functions performed by the system are:  RKE functions (Remote keyless features)  Hand Free functions for vehicle access and engine start  Immobilizer  LF antennae management

Page 5 / 8 2 Car Access There are two ways to Lock or Unlock the doors of the vehicle: 1. The first way is to use the remote key functionality (RKE) by pressing one of the “Lock” or “Unlock” buttons on the key fob. Data frames are then transmitted at 315 MHz or 433.92 MHz from the key fob of the car. The HFM_CMFB_01 processes the frames received and when the security code is correct, the doors are locked or unlocked automatically. 2. The second way is to use the hand free mode  Unlocking the vehicle : If the car is locked, when the door request switch located in the door is pressed by the car user which has a car key fob, the HFM_CMFB_01 transmits data frames at 125 kHz. When the key fob receives the data and recognizes the content of the inquiry, it transmits the code to the car at 433.92 MHz or 315 MHz (depending of key fob frequency type). The HFM_CMFB_01 processes the frames received and when the code is correct, the doors are automatically unlocked.  Locking the vehicle : If the car is unlocked, when the door request switch located in the door is pressed by the car user who has a car key fob, the HFM_CMFB_01 transmits data frames at 125 kHz. When the key fob receives the data and recognizes the content of the inquiry, it transmits the code to the car at 433.92 MHz or 315 MHz (depending of key fob frequency type). The HFM_CMFB_01 processes the frames received and when the code is correct, the doors are automatically locked. 3 Engine Start There are two ways to start the Engine: 1. When Hand free functions are disabled First the user has to hold the key fob in front of Kazashi for at least than 30s after one of the following action: press of the “START” button on the dashboard, open or close a door or press vehicle brake pedal. Each key fob has a transponder. When the key fob is hold in front of Kazashi antenna, the HFM_CMFB_01 sends a ‘transponder” recognition order to the key fob through the Kazashi antenna. The BCM performs a ‘transponder” authentication using 125 kHz transceiver. The key fob sends the authentication result to the HFM_CMFB_01. The central unit sends the start order to the engine control unit.

When Hand free functions are enabled The user does not need to hold the key fob in front of the Kazashi antenna. The key fob should only be inside the vehicle. When the “START” button is pressed, the HFM_CMFB_01 sends a recognize order at 125 kHz link via internal ferrite coil antennas. Receiving this order, the key fob sends authentication at 433.92 MHz or 315 MHz (depending of key fob frequency type). 4 Picture
