Entry System ECU FCC WARNING NOTICE 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) 2.Passsive 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 LF RF FOB 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 authorize the response. • Engine controller ECU receives the authorization for engine strat. • 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 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 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 influencei on the active entry system. 3.4.Door Locking Same functionality as the current one. 4.Entry System Options 4.1.System Schematic 4.2.Modules 4.2.1.FOB ECU 4.2.2.Entry System ECU OTHER ECUS LF (>2Kbps) RF (>4Kbps) Local Bus ECUECUECU Body Bus ENTRY SYSTEM ECU FOB 125kHz 315MHz FOB RF Amp LF Amp ASIC Z X Y Lock Unlock Trunk Key lock Emergency key (Transponder) 125kHz 315MHz ENTRY SYSTEM ECU MCU FT handle BT handle FH handle BH handle Trunk lid Engine start Body Bus Local Bus RF Amp LF Exciter LF Exciter LF Exciter LF Exciter LF Exciter LF Exciter Interior FTBTFHBH Trunk 315MHz 125kHz 5.System Characteristics 5.1.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 5.2.Exciter Locations Exterior exciters: 2 doors and 1 trunk Interior exciters: 1 driver’s sheet 2 column / shift lever (X-Y 2-Dimension) Figure 7 Antenna location can be different among of type of the vehicle (e.g. coupe, sedan, mini and stuff). Exterior Interior FT BT 5.3.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 Figure 8 Switch inputs can be different among of type of the vehicle (e.g. coupe, sedan, mini and stuff). FT BT 6.Electrical Characteristics 6.1.FOB • ASK / FSK modulation • Operating supply voltage 2.1V to 4.0V (3.0V Battery) • Operating supply current < 7mA • Stand-by current < 10.0uA • Operating ambient temperature -20 o C to +60 o C • Antenna direction 3-Dimension (X, Y, Z), to be considered • Battery life 2 Years (Low battery indication is considered) 6.2.Entry System ECU • Operating supply voltage 10.5V to 16.0V • Operating supply current < 15mA (20mA to 30mA) • Stand-by current < 4mA • Operating ambient temperature -40 o C to +85 o C • 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. Operation is subject to the following two conditions: (1) this device may not cause harmful inter…
