Tasks
The electronic ignition lock control unit has the following tasks:
- Central gateway (interface between CAN and chassis FlexRay (Flex E))
- Reading in of signals
- Evaluation of input factors
- Output of signals
Central gateway (Interface between CAN and chassis FlexRay)
The processor for controlling the central gateway functions acts as the interface between the following CAN buses:
- Interior CAN (CAN B)
- Diagnostic CAN (CAN D)
- User interface CAN (CAN HMI)
- Periphery CAN (CAN PER)
- Chassis FlexRay
Reading in of signals
The input factors are read in via the following connections:
- Direct line
- Interior CAN
- Diagnostic CAN
- User interface CAN
- Peripherals CAN
- Chassis FlexRay
Direct line
The following signals are read in via direct lines:
- Terminal 30
- Circuit 30b (emergency battery supply) (transmission 725)
- Status of KEYLESS-GO start/stop button (S2/3)
- Status of left front door rotary tumbler switch (A85s1) in left front door lock (A85)
- Electric steering lock control unit (N26/5) (transmission 716)
- KEYLESS-GO wake-up line
Interior CAN
The signals are read in by the electronic ignition lock control unit via the interior CAN.
Diagnostic CAN
The signals are read in from the electronic ignition lock control unit via diagnostic CAN.
User interface CAN
The signals are read in from the electronic ignition lock control unit via user interface CAN.
Peripherals CAN
The signals are read in from the electronic ignition lock control unit via periphery CAN.
Chassis FlexRay
The signals are read in from the electronic ignition lock control unit via chassis FlexRay.
Evaluation of input factors
The input factors that have been read in are evaluated by the integrated microprocessor whereupon the relevant signals are then issued.
Output of signals
The signals are issued over the following connections:
- Direct line
- Interior CAN
- Diagnostic CAN
- User interface CAN
- Peripherals CAN
- Chassis FlexRay
Direct line
The following signal is output via a direct line:
- Emergency path actuation (transmission 725)
Interior CAN
The signals are transmitted to the electronic ignition lock control unit via the interior CAN.
Diagnostic CAN
The signals are sent from the electronic ignition lock control unit via diagnostic CAN.
User interface CAN
The signals are sent from the electronic ignition lock control unit via user interface CAN.
Peripherals CAN
The signals are sent from the electronic ignition lock control unit via periphery CAN.
Chassis FlexRay
The signals are sent from the electronic ignition lock control unit via chassis FlexRay.
