High safety and economy with active rear axle steering

The front axles are steered mechanically via the steering wheel. Depending on the steering angle and speed, the rear axles are electrohydraulically actively steered. All axles of the vehicle are steerable.

P1 Road steering

The rear axles are steered depending on the speed. The higher the speed, the less the rear axles are steered. From a defined speed, they are set to straight ahead travel and locked in position.

P2 All-wheel steering

The rear axles are driven in so far that smallest turning radii result.

P3 Crab steering

All axes are steered in the same direction.

P4 Reduced shearing dimension

The rear axles are driven in such a way that the rear of the vehicle is minimised.

P5 Independent rear axle steering

The rear axles are steered via push buttons independently of the steering angle of the front axles.
