driving wheel is slipping, it suppresses the wheel
slippage. At this time, ASC-ECU controls the brake
fluid pressure of the driving wheel determined to be
slipping so that the torque is transferred to another
driving wheel. Basically, the operations of ABS
solenoid valve and ASC valve are the same. ASC-
ECU, the engine ECU, and A/T-ECU communicate
with each other via the CAN bus line. When the
accelerator pedal is depressed too far, the signal
requesting the engine speed reduction is sent to the
engine ECU. The ASC-ECU performs joint control
with A/T and secures the TCL controllability.
