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.
