How Active Stability Control (ASC) works
The ASC system controls the steering torque using the brake mechanism of each wheel.
For example, if the car starts to skid on a slippery surface and does not turn to the right enough, the system increases the braking force of the right rear wheel, thereby creating an additional torque. When the car turns too much, the system increases the braking force of the left front wheel, creating a restoring torque. In addition, if the car enters a turn at too high a speed, the system reduces engine power, allowing the turn to be completed without skidding.
The principle of operation of the active stability control system (ASTC)
The ATS system maintains vehicle stability in the event of wheel slippage by applying the brakes and reducing engine torque via the engine-ECU unit.
