NSK has successfully developed "electric power steering gear" to meet performance safety standards
2021-10-16Seiko Co., Ltd. (our company: Pinchuan District, Tokyo, takasuka Jinan, the representative executive agency of the ban on military service, hereinafter referred to as NSK) has developed an electronic control system in line with international performance safety standards for the automotive field in terms of electric power steering gear (hereinafter referred to as EPS), realizing the continuously improved high safety requirements in recent years, In addition, the product can also have driving assistance function corresponding to the height.
NSK strives to expand the sales of EPS for small cars to the world market. The goal is to make the overall sales of EPS reach 250 billion yen by March 2016.
Product features
1. It fully corresponds to the International Standard Specification for vehicle performance safety [iso26262]
*1
The development business process corresponding to international specifications is constructed, and the performance safety monitoring and performance safety evaluation are implemented. By further strengthening the diagnostic functions of microcomputer and torque sensor, the safety goal of automobile manufacturers is achieved.
*1: This design has the function of ensuring safety: when the electronic system fails, it can lock the cause and reduce the risk to an acceptable level. (international specifications being promoted with Europe as the center)
2. Miniaturization and lightweight of ECU
Through the use of non encapsulated semiconductors and semiconductor relays without mechanical connection, it is possible to miniaturize the radiator and reduce the number of parts, and realize the miniaturization and lightweight of 10% smaller than the original product (compared with the products in the early 2000s, the volume is reduced by 45% and the weight is reduced by 40%).
3. High added value
In recent years, EPS flexibly uses electronic control to continuously strengthen safety and comfort.
In order to correspond to the highly diversified control of the vehicle, the sensor of this product also has an angle sensor for detecting the operating angle based on the function of detecting the operating torque.
Purpose of the product
NSK's product fully corresponds to the requirements of international performance safety standards and specifications, and is being promoted to small vehicles in all aspects.
Product effect
• improved security
• reduce the driver's burden of operating the steering wheel
• reduced fuel consumption
