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 open (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 open • 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 handle sw 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 pushes door handle sw. • ECU sends LF-challenge via exterior antenna. • FOB sends RF-response to the ECU. • Door unlocking status is engaged. • Doors are opened. Figure 2 Door Handle SW LF RF FOB 2.2.Engine Start • User operates the engine start 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 operates the engine stop 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 influence on the active entry system. 3.4.Door Locking Same functionality as the current one. 3.5.Trunk Open 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) Local Bus ECUECUECU Body Bus ENTRY SYSTEM ECU FOB 125kHz RF (>2Kbps) 314.975MHz FOB RF Amp LF Amp ASIC Z X Y Lock Unlock Panic Emergency key (Transponder) 125kHz 314.975 MHz ENTRY SYSTEM ECU MCU Dr Door handle As Door handle Trunk Push knob (Engine start knob) Body Bus Local Bus LF Exciter LF Exciter LF Exciter LF Exciter Room1 Dr As Trunk 125kHz Dr : Driver Door Antenna As : Assist Door Antenna Trunk : Bumper Antenna Exterior Antenna Room1: Console Antenna Room2: Inst.
