Ⅰ. Introduction

Among the key vehicle operations of “go, turn, and stop”, steering is the main mechanism that governs the ability to turn. This makes it an indispensable part of the handling system of any automobile. Along with the popularization of automobiles, makers have added more advanced systems such as air conditioning and automatic transmissions. In this vein, power steering is an upgraded version of the basic system that gives drivers an easier time in operating their automobile.

At first power steering was confined to the luxury car segment as a high-end option, but as FF vehicles have become more popular power steering has been equipped on many more vehicles to avoid the issues with heavy handling that those automobiles are known to have. These days in Japan, most passenger vehicles, including mini vehicles and commercial vehicles, are equipped with power steering as a standard system.

Early on in the history of the development of power steering, the most common systems were hydraulic ones that used the power of the engine to engage a hydraulic pump. However, as fuel economy became more of a pressing issue for consumers and automakers vehicles began adopting electric power steering (EPS) systems instead. Most of the current models with power steering in Japan are using EPS systems over hydraulics. The most recent technological development in this segment is the steer-by-wire system that disconnects mechanical components and uses electronics to steer the vehicle. These systems have already been adopted by some models using EPS.



Ⅱ. Overview

This report on the Japanese market contains many mini vehicles and subcompact cars, which typically have lower engine output than regular passenger cars leading them to have hydraulic power steering systems. However, with the development of EPS systems leading to the obsolescence of piping systems for hydraulic fluids, even these smaller vehicles have been able to adopt electric systems. Also, following the ratification of the Kyoto Protocol in 2005 subsequent attempts to reduce CO2 emissions has led to the adoption of CVT and idling stop systems along with adoption of EPS systems in mid-sized and even larger vehicles.

As a result of the above development, almost all vehicle models in Japan now have power steering. However, some commercial vehicles or luxury and sports models where handling is a prime customer concern do not adopt power steering systems. Many models have been upgraded from hydraulic systems to EPS systems when they were facelifted or otherwise revised. The latest registration figures from 2016 show that mini vehicles and registered (excluding medium and large commercial vehicles) have an 85% adoption rate for EPS systems.

With the recent popularization of advanced driver assistance systems (ADAS) that interact with steering and handling functions like Lane Departure Warning Systems and Lane Keep Assist Systems, the electrification of power steering is essential. Furthermore, OEMs are focusing efforts and resources on automated driving research, which may lead to even further development in the area of steering systems. One example of this development is the 2014 V37 Nissan Skyline hybrid engine model (VQ37VHR), which has adopted a steer-by-wire system made by KYB. This kind of system is highly anticipated to be a core component of future automated driving systems.

As the complexity and functionality of electrical and electronic components for automated driving increases, the demand for safety systems that can prevent failure and mistaken operation is also rising. As a result of this IEC61508 standards have been introduced into the automobile industry, and in 2011 the ISO26262 international standards on functional safety for road vehicles came into effect. Steering lock and other critical failures of EPS systems are categorized into the most serious “ASIL-D” section of the standards, and as such makers are required to build in redundancy features to handle these cases.

The following section details the various types of power steering systems.

Hydraulic Power Steering

  1. Hydraulic Power Steering (HPS): The most conventional type, which utilizes the power generated by the engine to move fluid via a hydraulic pump.
  2. Electric Hydraulic Power Steering (EHPS): A system only used on luxury and sports models, it uses hydraulic fluids but an electric pump, meaning power from the engine is not necessary for operation.

[Electric Power Steering]

Systems are divided into three categories depending on the location of the electric motor.

  1. Column assist type (C-EPS): The motor is equipped on the interior column and powers the column shaft.
    Pros: Because the motor is in the interior there is more room in the engine compartment, which is particularly beneficial for minicars and subcompacts.
    Also good for water-proofing.
    Cons: It is hard to increase the size and power of the motor.
    Due to proximity to the interior cabin there can be noise.
    Steering feel can result in bad habits.
  2. Rack assist type (R-EPS): The motor is attached to the rack housing in the engine compartment and moves the rack directly. There are three sub-types: RD-EPS where the motor is above the rack gear, RC-EPS where the motor is on an angle to the rack gear, and RP-EPS where the motor is parallel to the rack gear.
    Pros: Driving feels good due to the direct force on the rack.
    Because the motor is in the engine compartment the noise is reduced.
    It is easy to increase the motor’s power for use in large vehicles or sports models.
    Cons: High cost, layout restrictions, water-proofing concerns.
  3. Pinion assist type (P-EPS/DP-EPS): The P-EPS type has the motor attacked to the pinion case in the engine room for direct power to the pinion gear. The DP-EPS system splits the system into two parts which are installed where the pinion meets the rack. This system suits more advanced or powerful models.
    Pros: The handling feels better than column assist type.
    Because the motor is in the engine compartment the noise is reduced.
    It is easy to increase the motor’s power for use in large vehicles or sports models.
    Cons: Layout restrictions, water-proofing concerns.
    Stress on the rack-and-pinion system is higher than with rack assist types.

Based on these characteristics different OEMs have different design considerations for their models. For example if we look at the difference between FR luxury/sports models from Toyota and Nissan, we can see that Toyota is using R-EPS, whereas Nissan is using HPS or EHPS systems. Toyota’s removal of hydraulic systems is in contrast to Nissan’s preservation of them, which may indicate differences in the stances of the companies towards the feel of handling and steering.

In the below list of equipment by model type, HPS, EHPS, and EPS systems have been detailed by sub-category wherever possible. Power steering system components such as hydraulic pumps and electric motors are also detailed. However, the ECU devices that are included in power steering systems are largely determined by the supplier, so they are detailed in the below section three rather than section six.

The recent trend for power steering units is to have the ECU and motor combined into the steering mechanism, forming what is called a power pack. In addition to this, a brushless motor is being built-in as a redundancy feature for safety. Generally speaking from a safety perspective, using a brush type motor is not realistic because the mechanism would need to have two commutators for the brushes on both sides. Despite the fact that they need multiple rotation angle sensors, it is much easier to engineer redundancy features for brushless motors. In addition to these options, the newly developed steer-by-wire systems using direct adaptive steering are also available, one of which was adopted by the Nissan Skyline V37 released in February 2014. This shows us that although power steering is ubiquitous these days, there are still technological developments taking place.



Ⅲ. Overview of major power steering suppliers

The major Japanese suppliers of power steering for passenger and small commercial vehicles are: JTEKT, NSK Steering Systems, Hitachi Automotive Systems (Hitachi AMS), KYB, and Showa. Some foreign suppliers also provide systems for some Japanese models: ZF TRW and Robert Bosch Automotive Steering.

Among these, only four companies are supplying hydraulic power steering systems in the Japanese market: JTEKT, Hitachi AMS, KYB, and ZF TRW.

JTEKT

  • JTEKT is a Toyota group supplier that was formed through a merger of Koyo Seiko and Toyoda Machine Works in January 2006. The company has also entered into joint business with former Nissan group power steering supplier Fuji Kiko. Through this they supply all major OEMs in the Japanese market. JTEKT is the top power steering supplier in Japan, with a 65% share of the market.
  • Koyo Seiko was, in 1988, the first company in the world to begin mass production of electric power steering systems. These were installed on Suzuki’s Cervo CG72V and CH72V models at the time.
  • JTEKT produces and sells HPS, EHPS, and EPS systems, but is recently shifting its product lineup towards EPS. As of 2016 over 80% of production was for EPS systems. For mini and subcompact cars the company supplies C-EPS and P-EPS/DP-EPS systems; for mid to large size passenger vehicles it supplies RP-EPS and RD-EPS systems. It also partners with other Toyota group companies like Denso to create power pack systems (combining the motor/solenoid with an ECU/MCU actuator), keeping the company ahead of its rivals in the segment.
  • Typically hydraulic systems are replaced with EPS systems on the launch of an all-new model. However, in some cases they are updated during the model’s life cycle, like with Toyota’s small commercial Probox Van and Succeed Van. This occurred because commercial vehicles generally have a longer model cycle and so the maker did not want to wait for an all-new model release.
  • JTEKT began production of a new RP-EPS system for Lexus’s luxury LC coupe at its Hanazono Plant in Aichi in December 2016, ahead of the model’s March 2017 launch.
    • It is expected that there will be a shift from conventional RD-EPS systems to the newer RP-EPS systems across many models. Specifically, RD-EPS systems were mainly only installed on FR models, so expansion of RP-EPS systems to more FF models above D-segment is anticipated. Furthermore, these systems are likely to be installed on light trucks that currently use hydraulic systems.
    • JTEKT expects growth in the Japanese, U.S., and ASEAN markets.
    • In light of these trends, JTEKT has set a global share target of 17.2% by 2020, and plans to develop more new products to achieve this goal.
    • To reach the above target, JTEKT plans to invest JPY 3.5 billion into its Hanazono Plant in November 2017 to bring a second line on stream. This will allow the company to produce a maximum of 60,000 RP-EPS units per month.
    • RD-EPS systems are designed with the motor positioned on the same axle as the rack, but in RP-EPS systems the motor and controller are parallel to the rack. This allows the EPS motor to generate torque according to the steering torque, moving the rack by transferring power from the belt to the ball screws.
  • In April 2015, JTEKT reached the milestone of 100 million EPS units produced. Currently it supplies over 15 companies with these systems, and has a global share of over 30%.
  • JTEKT began working with Denso in 2012 to create power pack type C-EPS systems (motor/ECU) for mass production as its Hanazono Plant.
  • System component suppliers
    • ECU/Motor: Supply to Toyota, Daihatsu, and Subaru are mostly from Denso, those to Nissan and Mazda are mostly from Mitsubishi Electric.
    • Most hydraulic pumps are self-produced, however some are obtained from KYB.

 

NSK Steering Systems

  • Formed as a spin-off from major bearing supplier NSK in 2001. All steering related businesses were transferred from NSK to NSK Steering Systems in 2002, forming the foundation of a new steering systems maker.
  • Holds the second place in terms of Japanese market share with just over 15%, but is rather behind JTEKT. Does not produce hydraulic systems, so just looking at EPS the market share is just under 20%.
  • Has eight production facilities in six countries: Japan (Soja and Akagi Plants), the U.S., Poland, India, Thailand, China (Dongguan and Hangzhou). Recently concentrated production of EPS systems for the U.K. market in Poland, started production in Thailand in 2011, and is expanding production capacity in India and China.
  • Only produces EPS systems. Supplies C-EPS systems for mini, subcompact and mid-size vehicles. Also supplies R-EPS and P-EPS systems for large passenger cars and sports models, but most production is of C-EPS and P-EPS (EPS:19.6% domestic share in 2014).
  • The company announced that it had developed the world’s lightest C-EPS system in January 2016. By miniaturizing torque sensors and deceleration gears the EPS unit was made 13% lighter than previous designs. Along with these changes, the torque sensors were upgraded to be able to continue operation even under low power conditions, and monitoring systems were added. Both of these contribute to higher safety of the new system, which will be adopted by mini vehicles and B-segment subcompacts as a next-generation environmentally friendly product. Mass production of the new system began in 2017.
  • The company also announced another new system in January 2016 that improves the sensation when the steering returns to a central position. The new system is dubbed the “active on centering system”, and reduces the burden on the driver for returning the steering to the central position by governing and revising the steering angle. The system employs steering angle sensors, and only works as part of an EPS mechanism. The company plans to commercialize the product sometime after 2017, and will continue to work on lowering the cost and improving the functionality.
  • System component suppliers
    • ECU: NSK Steering Systems does not produce ECUs, so it works with suppliers like Denso, Hitachi AMS, Nidec Elesys, Omron, Mitsubishi Electric and others to fulfill orders from OEMs.
    • Motor: Nidec, Mitsubishi Electric, Hitachi AMS, and Mitsuba’s parts are used.

 

Hitachi Automotive Systems (Hitachi AMS)

  • Formed as a unification of power steering business from Unisia Jecs and Bosch Brake Systems in 2001 under the name Unisia JKC Steering Systems. The company was absorbed into Hitachi’s automotive division in 2008, and then spun off under the current name in 2009.
  • Holds the third position in the Japanese market after NSK Steering Systems, with a share of just under 15%.
  • Produces the same range of products as top-placed JTEKT: HPS, EHPS, and EPS systems. However, recent sales figures show that HPS and EHPS systems are outselling EPS systems for Hitachi, which is counter to the general trend of the industry in Japan. This can be attributed to the fact that it supplies various companies, including Nissan, Mazda, and Mitsubishi Motors, with HPS systems, while supplying only Subaru with EPS systems. However, JTEKT and KYB have also started supplying Subaru, leading to the problem of how Hitachi AMS is going to expand its EPS sales.
  • The core characteristic of Hitachi AMS’s EHPS systems is that they only engage the hydraulic motor when steering, meaning the energy loss is limited. This system was co-developed with Nissan and is called the Electro-Hydraulic power steering system. This new EHPS system is installed on the Nissan Fuga and Cima models.
  • An upgraded version of the EyeSight system developed jointly by Subaru and Hitachi AMS, EyeSight Ver.3, is installed on the Subaru Levorg that was released in 2014. This new system includes features that work in unison with the EPS on the vehicle, such as active steering assist, mistaken reverse prevention, and lane keep. These are available as standard equipment on all but the low price versions. Subaru announced that it plans to release new models equipped with upgraded versions of EyeSight that can actually drive automatically on highways or automobile-only roads. Although the name has not been officially announced, this would basically be EyeSight Ver.4.
  • System component suppliers
    • ECU: Self-produced and also uses electronic parts from Denso and others.
    • Motor: Self-produced and also uses electric/electronic parts from Mitsuba and others.
    • Hydraulic pump: Self-produced and also uses parts from KYB.

 

KYB (Former Kayaba Kogyo)

  • Formally changed company name to KYB on October 1, 2015.
  • Is ranked fourth in the Japanese power steering market, after Hitachi AMS, with a share of just under 4%. However, KYB is a longstanding supplier of shock absorbers and other hydraulic systems and its business in the areas of driver support and autonomous driving is expected to expand.
  • Sales for the company are made up of shock absorbers and power steering systems, contributing 75% and 25% respectively. Among power steering systems, the company supplies HPS in Japan, Spain, and Thailand. With the decline in popularity of HPS systems it is expected that KYB will move quickly to improve its production capabilities for EPS systems in the near future.
  • Although it sells both HPS and EPS systems, it is in a similar situation to Hitachi AMS in that HPS is outselling EPS within Japan. However, the company began adding ECUs to its EPS systems in 2013, and started supply to Mazda, Mitsubishi Motors, Subaru, and Nissan.
  • Also supplies EPS for two-wheel ATVs and UTVs, as well as EPS and rear-wheel control products for racing vehicles.
  • KYB established a new electronics technology center in Sagamihara, Kanagawa in April 2012. This center is focused on improving development capabilities for EPS systems by working components such as ECUs, sensors, and electronics circuits. By recruiting more engineers and strengthening research into EPS systems, the company hopes to make the business a core pillar alongside its existing shock absorber segment. In particular the company is interested in further R&D into parts for EVs and the new steer-by-wire technologies that would form the backbone of next-generation EPS systems.
  • A new EPS system using a world-first system to capture steering signals using a wire harness and transmit them dubbed “steer-by-wire” was developed jointly with Nissan and equipped on the maker’s Skyline V37 released in February 2014. Nissan calls the technology Direct Adaptive Steering (DAS), and considers it one of its most advanced systems currently available for sale. Steering behavior is co-managed by three decentralized ECUs using the high-speed FlexRay transmission system. This system achieves a natural feel of handling and minimizes driver fatigue by carefully manipulating the steering angle actuator. The Skyline V37 is also equipped with active lane control and other driver support systems, and the steer-by-wire technology is likely to become a core component of future automated vehicles.
  • KYB announced in July 2015 that it had started working on integration of R&D for its shock absorber and steering businesses. Using the abovementioned steer-by-wire technology as a base, the company aims to increase the stability and comfort of vehicles by electronically controlling shock absorbers as well. KYB intends to bolster its position as a supplier of cutting-edge technology given the expected demand for ADAS and next-generation automated driving systems.

 

Showa Corporation

  • A major Honda group supplier. Mostly deals with chassis parts, power steering systems, and shock absorbers for two and four wheel vehicles. Its EPS business started when production and research functions were transferred from Honda. The first EPS system produced by Showa was a rack assist type EPS used on the 97M Accord. Following that the company added pinion assist types to its lineup, and currently sells both types. Previously HPS systems were also produced, but due to the cancellation of models using them the company now makes only EPS systems (excluding some support production functions). On March 30 2012 Showa announced in a press release that it had entered into negotiations for a strategic business agreement with TRW Automotive for the development and production of C-EPS systems. The two companies agree to split development, with TRW working on C-EPS systems and Showa working on DP-EPS systems.
  • Holds the fifth position in the Japanese market with a 1-2% share. This low share can be attributed to the fact that the company is not producing C-EPS systems, which are in high demand for subcompact models. Because of this, Showa is unable to take orders from Honda, despite being a group member, for the popular Fit subcompact and N series mini vehicle models.
  • Showa owns nine production and assembly facilities worldwide: Japan, China (three), Thailand, the U.K., the U.S., Canada (on stream since 2011), and Mexico (on stream since July 2015, approximately USD 20 million invested).
  • The company began production of a new dual pinion assist type electric power steering system (DP-EPS) at its Gotemba Plant in May 2015. The new system improves the handling feel and increases power generated, and is equipped on Mazda’s new Roadster. One reason for the improved handling feel is that the power assist mechanism is further from the steering section. The deceleration mechanism has also been situated independently from the steering column, which allows for optimization of power output depending on the rate of deceleration. The new system is also expected to be exported for use on Mazda’s Civic Type R to be sold in the U.K. Showa also anticipates global orders for its DP-EPS systems from Honda for the next generation 16M Civic and 17M CR-V, and intends to produce these at its Mexico plant for the U.S. market. With the expected rise in demand for EPS systems in the U.S., Showa will invest heavily in its Mexico plant to boost annual production capacity to 1 million units by 2018, an increase of 100% over 2016 levels.

 

ZF TRW (Former TRW Automotive Japan)

  • ZF Friedrichshafen AG completed the purchase of TRW Automotive Holdings Corp. for USD 11.7 billion in May 2015.
  • Initially TRW’s businesses were absorbed into ZF’s newly established Active and Passive Safety Technology division as a wholly-owned subsidiary called ZF TRW Automotive Holdings Corp. headquartered in the U.S. ZF intends to spend the next three to five years on post merger integration. Following this, ZF TRW revealed a new EPS system equipped on ZF’s Active Kinematic Control test vehicle in February 2016. The company expects to continue to release next-generation products for automated driving systems.
  • The joint 50/50 venture between ZF and Bosch, ZF Lenksysteme GmbH has been sold to Bosch and re-incorporated as Robert Bosch Automotive Steering GmbH.
  • After TRW was made a wholly-owned subsidiary of ZF the various corporate entities operating in Japan were consolidated in Match 2017. The ZF Tokyo HQ was moved to TRW’s offices in Yokohama and operations were centralized there under the name ZF Japan. As a note, the Japanese company name does not include TRW currently, but to keep references consistent with the name of the American operations ZF TRW is used in this report.
  • The former TRW Automotive Japan was a wholly-owned subsidiary of the U.S. TRW Automotive. The company has produces airbags, seat belts, steering systems, driver assistance systems, brakes, ABS, ESC, and EPS systems. The company has set goals for partial automated driving through the use of advanced driver assistance systems.
  • Production in Japan started in the 1970’s with steering parts like gears and ball joints being supplied to Japanese auto makers. Because the company supplies for only some Mazda and Mitsubishi Motors models its share in the Japanese market has stalled at just over 2%.
  • ZF TRW supplies HPS, EHPS, and EPS systems. Among the EPS types, it produces C-EPS and R-EPS. Its rack assist type uses a belt drive and ball nut mechanism to deliver power to the rack gears.
  • Although the company only supplies Mazda and Mitsubishi Motors in Japan, globally it has business with VW/Audi, Ford, Volvo and other makers. It started producing EPS systems in 2001, and in 2014 reached the production milestone of 26 million units.
  • The C-EPS systems used in the Mazda Demio DJ series (produced in Japan, Mexico, and Thailand) and CX-3 (produced in Japan) are produced solely by TRW China for global export. General EPS production is conducted in five regions: Poland, Spain, Slovakia, China, and Brazil.
  • TRW America’s latest product, a third generation column shift type EPS in which the ECU, motor, and core components have been modularized, was made available in Europe and China in 2014. The company plans to ramp up annual production of this system to 1 million units. Models adopting the new system include VW’s Polo/up!/e-up!, Audi’s S1, Skoda’s Rapid/Fabia/Citigo, and Fiat’s Fiat 500L and Viaggio (China GAC Fiat).
  • ZF TRW is also in the process of approaching Japanese parts makers operating in developing countries with business proposals for supplementary production and co-development. The company has placed particular emphasis on expanding its presence in Brazil, where it is a late entry, with the goal of strengthening business relationships and increasing its operations in Japan.

 

Robert Bosch Automotive Steering GmbH (Former ZF Lenksysteme GmbH)

  • This company was originally a 50/50 joint venture between Bosch and ZF Friedrichshafen AG, but was fully purchased and made a wholly-owned subsidiary of the Bosch Group on January 30, 2015. The new company functions as a steering systems supplier, and has a share of less than 1% in the Japanese market.
  • Production facilities are in Europe, North America, China, India, Brazil, and Malaysia.
  • As of April 2016, the company’s products in the Japanese market were the DP-EPS system equipped on the Honda Odyssey released in November 2013, and the R-EPS system equipped on the Honda Legend released in February 2015.
    • The company does not produce anything in Japan. DP-EPS systems for the U.S. and China models of the Honda Accord are produced in each of those countries.

 

Thyssenkrupp Presta AG

  • ThyssenKrupp is a German maker of iron, steel, and industrial products. Beginning with iron, steel, stainless steel, and compound metals, the company now has businesses for automotive parts, shipbuilding, elevators, and large bearings. ThyssenKrupp Presta is the subsidiary that handles automotive steering, and the company produces steering shafts and columns modules as well as power steering (HPS and EPS) systems.
  • The company’s first entry into the EPS market was with the release of the BMW X3 in 2010. Following that, the company has supplied systems for BMW and Daimler’s D/E-Segment vehicles.
  • Only produced R-EPS systems until 2013 (450,000 units shipped in 2012), but since then has added C-EPS systems to its product lineup.
  • The company is actively courting business with Japanese OEMs, such as Mazda’s seventh generation Axela (Mazda 3), and is using production bases in China to enhance its competitiveness to participate in the Japanese market.
