Seiko Co., Ltd. (headquartered in Shinagawa ku, Tokyo, with the representative of the enforcement agency, Takashi Takarazuka, hereinafter referred to as NSK) has developed an electronic control system for electric power steering (EPS) that meets international standards for performance and safety in the automotive field. This system has achieved the high safety requirements that have been continuously improved in recent years, and this product can also provide high-level driving assistance functions.
NSK aims to expand the sales of EPS for small cars to the global market. The goal is to achieve an overall sales revenue of 250 billion yen for the EPS business by March 2016.
Product features
1. Fully correspond to the international standard specifications for automotive performance and safety [ISO26262]
*1
We have established a development business process that corresponds to international standards, implemented performance safety monitoring and performance safety evaluation. By further strengthening the diagnostic functions of microcomputers and torque sensors, the safety goals of automobile manufacturers have been achieved.
*1: This design has the function of ensuring safety: when the electronic system fails, it can lock in the cause and reduce the risk to an acceptable level. (International standards being promoted with Europe as the center)
2. Small and lightweight ECU
By using unpackaged semiconductors and semiconductor relays without mechanical connections, it is possible to miniaturize 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, the volume has been reduced by 45% and the weight has been reduced by 40%).
3. High value-added
In recent years, the flexible use of electronic control in EPS has continuously strengthened safety and comfort.
In order to correspond to the highly diversified control of vehicles, the sensor of this product is equipped with an angle sensor that detects the operating angle in addition to the function of detecting the operating torque.
The purpose of the product
NSK's product fully complies with the international standard specifications for performance and safety, and is being promoted to small cars in all aspects.
The effect of the product
• Improved security
• Reduced the burden on the driver to operate the steering wheel
• Reduced fuel consumption
