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

Nippon Seiko Co., Ltd. (Headquarters: Shinagawa-ku, Tokyo, Representative Director and Executive President Norio Otsuka, hereinafter referred to as NSK) has developed electric power steering gears (hereinafter referred to as EPS) for the automotive field that meet international standards for performance and safety The electronic control system has realized the high safety requirements that have been continuously improved in recent years, and this product can also correspond to a high degree of driver assistance functions.

NSK intends to expand sales of EPS for small cars to the global market. The goal is to achieve sales of 250 billion yen in the EPS business as a whole by March 2016.

Product Features

1. Fully correspond to the international standard specification of automobile performance safety [ISO26262]

*1

Established development business processes corresponding to international standards, and implemented performance safety inspections and performance safety assessments. By further strengthening the diagnostic functions of the microcomputer and torque sensor, the safety goal of the automobile manufacturer has been achieved.

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

2. Small and lightweight ECU

By adopting non-packaged semiconductors and semiconductor relays without mechanical connections, it is possible to miniaturize heat sinks, etc. and reduce the number of parts, and achieve a volume reduction of 10% compared to the original product (compared to the product in the early 2000s, the volume is 45% smaller and 40% lighter) miniaturization and lightening.

3. High added value

In recent years, EPS has continuously enhanced safety and comfort by utilizing electronic control flexibly.

The sensor of this product has a built-in angle sensor for detecting the operating angle in addition to the function of detecting the operating torque in order to cope with the highly diversified control of the vehicle.

Use of the product

This product of NSK fully corresponds to the requirements of international standards for performance and safety, and is being promoted to all aspects of small cars.

Product effect

• Improved security
