NSK successfully develops "electric power steering" that meets performance safety standards

Nippon Seiko Co., Ltd. (Headquarters: Shinagawa-ku, Tokyo; Chairman and CEO Norio Otsuka, hereinafter referred to as NSK) has developed electric power steering (hereinafter referred to as EPS) for the automotive field that meets international performance and safety standards. The electronic control system of the standard meets the high safety requirements that have been increasing in recent years, and this product can also support high-level driving assistance functions.

NSK aims to expand sales of EPS for small cars to the global market. The goal is to increase the overall EPS business sales to 250 billion yen by March 2016.

Product features

1. Fully corresponds to international automotive performance safety standards [ISO26262]

*1

We established a development business process that corresponds to international standards, and implemented performance safety monitoring and performance safety assessment. By further strengthening the diagnostic functions of microcomputers and torque sensors, we have achieved the safety goals of automobile manufacturers.

*1: This design is equipped with functions to ensure safety: when an electronic system fails, the cause can be identified and the risk reduced to an acceptable level. (International standards that are being adopted mainly in Europe)

2. Small and lightweight ECU

The use of package-free semiconductors and semiconductor relays without mechanical connections has made it possible to downsize heat sinks and reduce the number of parts, achieving a 10% reduction in volume compared to the original product (compared to products in the early 2000s) 45% smaller and 40% lighter).

3. High added value

In recent years, EPS has made flexible use of electronic control to continuously enhance safety and comfort.

In order to cope with the highly diversified control of vehicles, the sensor of this product has a built-in angle sensor that detects the operating angle in addition to the function of detecting the operating torque.
