The analog output signals
Assigning control unit switching the PPC (N15 / 6):
?· Definition of working conditions;
?· Processing of incoming signals CAN;
?· The calculation of operating variables;
?· Activation of the actuators;
?· Saving and issuing of diagnostic data;
?· Processing incoming analog signals.
Only the control unit N15 / 6 is able to produce shift calculation of parameters based on the analysis of analog signals from sensors determining selected information transmission speed clutch, clutch travel, and a request for switching the hydraulic pressure.
12 + 2-pin and 18-pin control unit is fixed with safety clamps.
The main functions of the control ASG stored in a modular program code ECU, where each task in a separate block. Nevertheless, occurring interdependence define a connection of a network.
Circulation period determined by the frequency of the processor units and is approximately 10 ms.
Information transmitted by the control unit switching the PPC (N15 / 6) on the CAN bus
The control unit ME-SFI (N3 / 10) / CDI (N3 / 9):
?· Emergency stop of the engine;
?· Current transfer;
?· The required transmission;
?· Emergency operation mode of transmission;
?· Creeping torque;
?· Switching to manual mode;
Dashboard (A1):
?· Current transfer;
?· Mode of transmission;
?· Error messages / faults.
The control unit ESP / BAS (N47-5):
?· Option transmission;
?· Current transfer;
?· The required gear.
The information received by the control unit switching the PPC (N15 / 6) with CAN bus
Dashboard (A1):
?· Opening / closing the driver's door;
?· The temperature of the outside air.
The control unit ME-SFI (N3 / 10) / CDI (N3 / 9):
?· Pedal position;
?· Emergency mode;
?· Operation Tempostat;
?· The idle speed;
?· Activating the speed limiter;
?· Activation of engine speed limiter;
?· Inertial cutoff of fuel supply;
?· The torque of the engine;
?· The temperature of the oil.
Front control unit SAM (N10 / 1):
?· The function of awakening;
The control unit ESP / BAS (N47-5):
?· Speed of wheels;
?· The gauge-switch of stoplights;
?· Parking brake;
?· The signal for the control unit ESP.
The control unit EIS (N73):
?· State the terminals.
