Summary

This second edition Steering Systems Report provides a detailed market overview including all the latest technological developments within the sector. Also covered are profiles of all the major players within the industry.

The report goes into details of how the market is structured for EPS, Hydraulic, EHPS, Active Steering, Total Chassis Control, Steer-by-wire, and Four Wheel Steering.

Report Background

The steering systems market is in the middle of a technology shift that is only likely to accelerate as electrification and the demands for greater fuel economy increase. This places big demands on the sector for development and introduction of appropriate solutions for the industry.

The changeover to EPS is accelerating, driven by government and consumer demands for more fuel efficiency. Most European platforms for 2012 and beyond want EPS as standard. New packages will be required as demand for low-cost, low-function EPS has been identified for emerging markets, while in mature markets, active steering and four-wheel steering have achieved solid footholds.

Longer term there is the prospect of Steer-by-wire in production by 2015, and total Chassis Control systems that tie active steering to braking, acceleration and suspension control are being developed.

The report identifies and profiles nine major external players in the supply of steering systems: ZF-Lenksysteme GmbH, TRW Automotive Holdings Corp., Delphi Corp., JTEKT Corp., ThyssenKrupp AG, Showa Corp., NSK Corp., Mando Corp. and Tedrive Holding B.V.
