Function
The electromechanical power steering is an
active system. It operates in relation to
– the driving speed,
– steering moment and steering speed,
– steering angle and
– return forces.
It therefore provides optimum steering assistance
for the driver.

You will find detailed information in the self-study program 317 "The Electromechanical Power
Steering with Dual Pinion".
The assist power of the electric motor flanged on
parallel to the rack and pinion is transferred to
the rack via a second pinion (input pinion). This
pinion meshes in the steering rack and transfers
the assist power.
