FOB Entry System ECU FCC WARNING NOTICE ALPS ELECTRIC Co., LTD 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) ALPS ELECTRIC Co., LTD 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. Proximity sensor 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 Figure 2 FOB ALPS ELECTRIC Co., LTD 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. 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 ALPS ELECTRIC Co., LTD 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 ALPS ELECTRIC Co., LTD 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.
