The Integral Active Steering (SA 2VH) increases the dynamic performance of the vehicle as well as ride comfort.
The variable steering gear ratio of the active steering unit reduces the steering effort to approximately two turns of the steering wheel to bring the front wheels from stop to stop. In a low speed range of around 60 km/h (40mph) the variable steering gear ratio on the front axle is coupled with a counter steering angle on the rear axle. This makes the vehicle more maneuverable.
With increased speed, the steering angle support is delayed. The steering gear ratio becomes less direct. At the same time, the steering strategy of the integral active steering changes. Whereas the steering is counter to the direction of the front axle at low speeds, the steering angle is increasingly in the same direction as the front axle at high speeds. This has a stabilizing effect on the vehicle.
