What is Integral Active Steering?

For a large luxury car, the car’s wheelbase is longer continue to bring good comfortable ride space, but it also brings to the vehicle’s handling certain negative impact. Whether turning radius at low speeds or when driving high speed stability will be compromised. By the addition of rear-wheel steering system can compensate for the vehicle driving characteristics caused by the increase in wheelbase, while allowing a luxury car also has a good driving pleasure.
This principle active rear steering system is not complex, is a set screw nut mechanism, the screw drive motor to generate a drive nut to move axially. This axial movement will lead to a slight steering rear wheels when the vehicle speed is 60km / h or more, the front wheels with the rear wheels deflected improve the stability of the high-speed cornering. When 60km / h or less the reverse deflection, increase the flexibility of the vehicle.
This active rear steering system of the technological content mainly concentrated in the control system work, it needs to accept various vehicle dynamic driving signal, and then outputs a comprehensive judgment with appropriate steering angle, any calculated mistakes are likely to result in loss of vehicle control, particularly when high-speed driving.
