Preface This document describes the requirements and operation of the Passive Entry System. However, this document is especially for the Entry system ECU (acronym for Electric Control Unit) and the FOB. The FOB consists the following functionality for passive access and active access: • Door unlocking / locking (however, only for request by means of switch operation) • Trunk unlocking / locking (however, only for request by means of switch operation) • LF decoding • RF encoding • Communication data encryption (cryptograph, anti-collision, rolling code and stuff) And the entry system ECU consists of the following functionality: • Door unlocking / locking • Trunk unlocking / locking • Engine start (/ stop) • LF encoding • RF encoding • Communication data encryption (cryptograph, anti-collision, rolling code and stuff) • LF antenna unit control • Communication with the node ECUs connected to the body bus (e.g. CAN, J1850, customer dependent bus) As a further function, both the FOB and the entry system ECU provides the following function: • Learning mode for programming the manufacturing data and stuff • Data locking and password protection • Diagnostic (based upon ISO9141 if required) FORMAT NO. FIRMWARE_A(VER 0.01) 2. Passive Accsess Entry Functionality A proximity sensor located on, for example the door handles, mirrors and trunk lid will be used for proximity check if user is in neighborhood of the vehicle. The switch input will trigger for unlocking and open the doors and trunk. Figure 1 2.1.Door Unlocking • User pull / touch the door handle (sensing of door handle switch). • ECU sends LF-challenge via exterior antenna. • FOB sends RF-response to the ECU. • Door unlocking status is engaged. • Doors are opened. Figure 2 Proximity sensor Switch input (door handle) LF RF FOB FORMAT NO. FIRMWARE_A(VER 0.01) 2.2.Engine Start • User pushes / operate the engine start button / knob. • ECU sends LF-challenge via interior antenna. • FOB sends RF-response to the ECU. • Immobilizer ECU receives and authorizes the response. • Engine controller ECU receives the authorization for engine start. • Start the engine. Figure 3 2.3.Engine Stop • User pushes / operate the engine stop button / knob. • ECU communicates with the other ECU for engine start request. • Engine controller ECU receives the request. • Stop the engine Figure 4 LF RF FOB FORMAT NO. FIRMWARE_A(VER 0.01) 2.4.Door Locking (Push switch) • User closes the door and pushes the switch (sensing of door locking switch). • ECU sends LF-challenge via exterior antenna. • FOB sends RF-response to the ECU. • Door locking status is engaged. • Doors are locked. • (Indicates the door locking status by means of Flasher / Buzzer or stuff) Figure 5 FORMAT NO. FIRMWARE_A(VER 0.01) 3. Active Access Entry Functionality 3.1.Door Unlocking Same functionality as the current one. 3.2.Engine Start This function does not effect on the active entry system. 3.3.Engine Stop This function does not have influence on the active entry system. 3.4.Door Locking Same functionality as the current one. FORMAT NO. FIRMWARE_A(VER 0.01) 4. System Characteristics 4.1.Antenna Areas Exterior operating range: 0.8m to 1.5m Interior operating range: Only inside the car Number of the exterior exciters: max. 5 (min. 2), however, it is depending on the type of the vehicle. Number of the interior exciters: 1 (1-Dimmension) or 2 (2-Dimension required) Figure 6 Exterior antenna functionality: • Unlock / lock doors and trunk. • Activate / deactivate alarm system. • Activate immobilizer Interior antenna functionality: • Deactivate immobilizer • Engine start Exterior Interior FT BT FORMAT…
