Integrated Active Drive System
Comprises a suite of advanced technological aids linked, and working together, to assist the driver in maintaining full control of the vehicle.
How does it work?
In most vehicles the various elements of stability control (including the anti-lock brakes, traction control, stability control and power steering) work independently of the 4WD torque control system.
High speed electronic communication is used to link all these elements together in real time in the Integrated Active Drive System.
- Active Torque Control uses an electronically controlled coupling as the centre differential. This splits the torque distribution during acceleration between 2WD and 4WD as conditions dictate, without conscious input from the driver
- Anti-lock Braking System (ABS) uses sensors to momentarily release the brake from whichever wheel is locking to provide maximum braking effect at all times
- Traction Control (TRC) uses ABS to apply correction by braking any slipping wheel under acceleration so that more power is transmitted through the opposite non slipping wheel
- The VSC system checks twenty-five times every second where the driver is steering the car and the actual track the vehicle is taking. When it detects that a skid or slide is starting it instantly applies a correction, via the TRC and ABS systems
- Electric Power Steering (EPS) works with VSC to assist the driver by making it easier to apply the correct steering action and harder to apply the incorrect action
- Safer day-to-day driving. Can help prevent accidents
- More precise control in corners and under heavy braking and acceleration
- Improved stability
- Minimal wheel spin under hard acceleration or on slippery surfaces
- The vehicle is more manoeuvrable
