Volkswagen Group Components
In the future, VW will strengthen the development and in-house production of parts for EVs.
Established Volkswagen Group Components in January 2019.
In May 2019, signed a collaboration agreement with NSK for steering development.
VW Group and NSK:
As the first collaboration, we jointly developed a pinion-type EPS for VW’s MEB (Modular Electric Drive Toolkit) (Fig. 1).
Pinion EPS:
Currently, the “EPS installed in the mass-produced VW / MEB” is a pinion type.
This part will be the second generation product.
Other companies supplied parts for the first-generation EPS for VW / MEB.
How pinion EPS works:
Reducer that amplifies the torque of the motor,
Torque sensor that detects steering force,
Rudder angle sensor that detects the rudder angle,
It consists of an ECU (electronic control unit).
