Functional safety compliant electric power steering from NSK
25 April 2015
NSK has developed a new electric power steering (EPS) system that is compliant with ISO Functional Safety for automobiles.
In using packageless semiconductors and semiconductor relays that have no mechanical contacts, NSK has achieved a more compact, lighter product, making the radiators more compact and reducing the overall number of components.
The result is a 10 percent decrease in volume from that of the most recent conventional product (or a 45 percent volume decrease and 40 percent weight decrease from the original product which came out in the previous decade).
In recent years, EPS has provided electronic controls for greater safety and comfort. The new product features built-in steer angle sensors in addition to internal steering torque sensors to provide compatibility with a variety of high performance vehicle controls.
