Engine Intervention
In the event of wheel-slip the ABS / DSC module calculates
the torque, which should be applied by the engine to reduce
the wheel-slip (this torque does not exceed driver demand).
Engine torque reduction is then requested from the PCM via
the CAN bus. The PCM, in response to these signals, reduces
engine torque by controlling the ignition and fuelling. A
traction control gearshift pattern is automatically selected
within the automatic transmission software whenever
traction control is active.
Brake Intervention
This function operates by increasing the pressure in the
brake caliper of the slipping wheel, by closing the separation
valve and the inlet valve of the non-slipping wheel and
running the modulator pump. This takes fluid from the fluid
reservoir via the non-actuated master cylinder and
pressurizes the brake caliper. The pressure is modulated at
the caliper via the inlet and outlet valves to achieve the
desired wheel-slip target to maximize traction.
