BMW 7 Series: Introduction
BMW Steering Systems - Innovative and technically always something special
Since the introduction of the first EPS electric power steering system on the E85 in 2002, the variety of technical innovations on steering systems has rapidly expanded. Before then the following systems were used:
- Hydraulic power steering
- Speed-sensitive power steering (Servotronic)
The next major step with steering systems then came with the E60 and the revolutionary Active Steering system, which not only had the Servotronic function but also incorporated speed-sensitive modulation of the steering angle.
BMW also improved the electric power steering (EPS) system and used it in a variety of forms.
The main difference between hydraulic and electric power steering is in the method of generating the power assistance force that reduces the amount of force that the driver has to apply to the steering wheel.
In order to further inventively optimize the advantages of Active Steering on the new 7 Series, Integrated Active Steering has now been developed and is described in this document.
