Seiko (Xinhua: Tokyo Shinagawa, and banned service on behalf of the executive service agency, Zhong Ji grew up male named NSK) in the electric power steering system (hereinafter referred to EPS), the electronic control system for automotive field developed standard specification and performance of international security, to achieve a high safety in recent years to improve the requirements of this product, and also corresponding driving assistance function height.
NSK seeks to expand EPS sales for small cars to the world market. The goal is to make sales of EPS's business as high as 250 billion yen by March 2016.
1. fully correspond to automotive performance safety International Standard Specification [ISO26262] *1
Construction of corresponding international specification development business process, implementation of performance safety monitoring and performance safety assessment. By further strengthening the diagnosis function of microcomputer and torque sensor, the safety target of automobile manufacturer is achieved.
*1: this design has the function of ensuring safety: when the electronic system fails, the reason can be locked and the risk is reduced to an acceptable level. (European centric, international standards are being adopted)
Small and lightweight 2.ECU
The package of semiconductor and semiconductor relay without mechanical connection, so that the number of small parts and reduce heat sinks and the possible implementation than the original product size decreased by 10% (compared with the beginning of the 2000s product volume reduced by 45%, reduces the weight of 40%) of the compact and lightweight.
3. high value-added
In recent years, EPS flexible use of electronic control, security and comfort has been strengthened.
In order to control the height of vehicle, the sensor of the product is equipped with an angle sensor that detects the angle of operation on the basis of detecting the operating torque.
NSK's product, which meets the international standards of performance and safety requirements, is being extended to small cars in all its aspects.
• improved security
• reduces the burden on the driver's steering wheel
• lower fuel consumption
