The ABS/ASC control unit can determine the current load status of the engine with the aid of the input signals engine speed and current throttle angle. These factors serve as the basic data for possible engine intervention during ASC activation.
The ABS/ASC control unit can initiate the following engine interventions by outputting digital signals (0 V / 12 V) on three lines to the DME:
Engine intervention |
Effect |
Type of control |
|---|---|---|
Ignition timing adjustment |
Smooth reduction of drive torque |
ASC |
Blanking out ignition |
Fast reduction of drive torque |
ASC |
Increase in idle speed |
Reduction in engine drag torque on vehicles with manual transmission |
MSR |
The above-specified engine interventions are supplemented as required by control of the choke and influencing the individual rear wheel brakes.
