Functional networking: Notes
For implementation of the Stop&Go function, a complex system network with distributed functions in other control units is necessary. Buses connect the ICM control unit with these other control units.
The following control units are networked for the overall function:
| Control unit | Function |
|---|---|
| DME or DDE: Engine control | Implementation of the torque request "Engine on" signal |
| DSC: Dynamic Stability Control | Driving condition Implementation of braking intervention |
| SZL: Steering column switch cluster | Operating lever Steering angle |
| CIC: Navigation system | Data from navigation system (influence on control variables) |
| Instrument panel: Instrument panel | Diagram of the displays (ACC and Check Control messages) |
| CAS: Car Access System | Terminal status and wake-up line Door contact |
| EGS: Transmission control | Driving position |
| AHM: Trailer module | Identification of trailer towing |
| ACSM. Crash safety module | Driver's seat occupancy (driver intends to exit) Seat belt buckle contact (driver intends to exit) |
| RLS: Rain/rain/light sensor | Road condition (wet) |
| FRM: Footwell module | Activation, hazard warning flashers, door contact |
