FIRMWARE_A(VER 0.01) 1.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. Proximity sensor Switch input (door handle) 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. LF RF FOB Figure 2 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. RF LF FOB 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 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: Interior operating range: 0.8m to 1.5m Only inside the car Number of the exterior exciters: Number of the interior exciters: max. 5 (min. 2), however, it is depending on the type of the vehicle. 1 (1-Dimmension) or 2 (2-Dimension required) Interior Exterior FT BT Figure 6 Exterior antenna functionality: • Unlock / lock doors and trunk. • Activate / deactivate alarm system. • Activate immobilizer Interior antenna functionality: • Deactivate immobilizer • Engine start FORMAT NO. FIRMWARE_A(VER 0.01) 4.2.Exciter Locations Exterior exciters: Interior exciters: 2 doors and 1 trunk 1 driver’s seat 2 column / shift lever (X-Y 2-Dimension) Interior Exterior FT BT Figure 7 Antenna location can be different among of type of the vehicle (e.g. coupe, sedan, mini and stuff). FORMAT NO. FIRMWARE_A(VER 0.01) 4.3.Switch Input Locations (Door handle, Touch sensor) There are some kind of sensors, for instance the door handle contact switch and touch sensor, will be used as a triggering for unlocking and open the door. Switch inputs: 2 doors and 1 trunk FT BT Figure 8 Switch inputs can be different among of type of the vehicle (e.g. coupe, sedan, mini and stuff). FORMAT NO. FIRMWARE_A(VER 0.01) • FCC WARNING Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. NOTICE This device complies with Part 15 of the FCC Rules.
