Self Study Program 399 – Electromechanical Steering with Parallel-axis Drive Design and Function
VAG SSP 399. The electromechanical power steering has many advantages compared with a hydraulic steering system. It assists the driver and relieves the physical and mental burden for him. It works on demand, i.e. only when the driver requires steering assistance. The steering assistance depends on the vehicle speed, the steering movement and the steering angle.
The parallel-axis power steering is part of the latest generation of electromechanical steering systems. This steering system uses a combination of tried and tested components and innovative new features. It is currently only used in left-hand-drive vehicles.
The electromechanical steering with parallel-axis drive is a VW development from the Braunschweig development team. It is also produced at the Braunschweig site. This self-study programme explains how this electromechanical power steering with parallelaxis drive works in detail.
