7 min read

Automotive steering procedure research: EPS dominates the sector, SBW prepares for totally autonomous driving. Immediately after hundreds of yrs of growth, automotive steering units have derived HPS, EHPS, EPS, SBW and other kinds.

New York, Aug. 16, 2021 (World NEWSWIRE) — announces the release of the report “China Automotive Steering Technique Business Report, 2021” –
At current, HPS (hydraulic power steering) and EHPS (electronic hydraulic power steering) have been widely used in professional autos, even though EPS (electrical electricity steering) is generally applied to passenger vehicles, and SBW (Steer-by-Wire) has the least expensive penetration level.

EPS occupies the passenger motor vehicle current market, although HPS and EHPS dominate the business automobile industry

In Chinese passenger motor vehicle steering procedure market place, the share of EPS has improved from 80.1{9f8850bc8f664a2ac1fdee25ffd85a3cdac362824700ab0655dbcffd0add5cb2} in 2016 to 96.4{9f8850bc8f664a2ac1fdee25ffd85a3cdac362824700ab0655dbcffd0add5cb2} in 2020 only a little selection of passenger automobiles adopt HPS and EHPS methods. Somewhat talking, the better the price tag of cars, the better the proportion of EPS alternatives applied.

Owing to its modest dimensions, lower ability usage, mild body weight and adaptability, EPS is the initial alternative for new electrical power motor vehicles. EPS accounted for 99.91{9f8850bc8f664a2ac1fdee25ffd85a3cdac362824700ab0655dbcffd0add5cb2} of the new energy passenger motor vehicle marketplace in 2020, and this proportion is envisioned to get to 100{9f8850bc8f664a2ac1fdee25ffd85a3cdac362824700ab0655dbcffd0add5cb2} in the potential.

HPS and EHPS are typically viewed in most industrial automobiles, especially major-obligation motor vehicles, many thanks to their high ability and reduced charges. In 2020, China’s professional vehicle steering techniques had been continue to dominated by HPS and EHPS, of which EHPS made up for 40.1{9f8850bc8f664a2ac1fdee25ffd85a3cdac362824700ab0655dbcffd0add5cb2}. Nonetheless, the sector shares of HPS and EHPS will little by little be grabbed by EPS in the potential simply because they not only eat heaps of ability, but also lead to hydraulic oil leakage, which do not meet environmental protection necessities.

The EPS penetration level of area passenger motor vehicle brand names is progressively growing
In the Chinese passenger motor vehicle industry, the EPS penetration charge of Chinese passenger automobile brand names is significantly decrease than that of foreign passenger auto brand names. In 2020, the previous was 90.7{9f8850bc8f664a2ac1fdee25ffd85a3cdac362824700ab0655dbcffd0add5cb2}, when the latter strike as substantial as 100{9f8850bc8f664a2ac1fdee25ffd85a3cdac362824700ab0655dbcffd0add5cb2}. Having said that, with the gradual tightening of environmental security, area makes will progressively abandon the polluting steering systems these kinds of as HPS and EHPS. By 2026, the EPS penetration price of Chinese passenger motor vehicle brand names is expected to arrive at 100{9f8850bc8f664a2ac1fdee25ffd85a3cdac362824700ab0655dbcffd0add5cb2}.

Multinational organizations dominate the marketplace, although nearby firms attempt to endure

At current, the world automotive steering process market is mostly occupied by distributors these types of as JTEKT, Bosch, ZF, ThyssenKrupp, NSK, Mando, Hitachi Astemo. These multinational providers have deployed the Chinese industry through sole proprietorship or joint ventures, firmly occupied the supply channels of luxury and joint undertaking manufacturer automakers, and penetrated into the source process of community automakers.

There are additional than 100 neighborhood providers in China, but most of them are small companies focusing on the aftermarket with weak competitiveness. Zhejiang Shibao, CAAS, Elite, Nexteer Automotive, etc. which have rather strong competitiveness can contend with multinational giants. For case in point, Nexteer Automotive and Zhejiang Shibao have entered the offer methods of American, German and Japanese automakers by advantage of their robust power, and have taken areas in the siege of multinational businesses.

Big distributors and automakers have deployed SBW which will be promising in the future

The most significant distinction amongst SBW and EPS is that the former gets rid of the mechanical link in between the steering wheel and the rack and takes advantage of European to transmit commands as a substitute. SBW capabilities rapidly response, adaptable installation, lighter excess weight, and improved collision safety.

SBW engineering was proposed as early as 1950. After a long time of growth, it has now been mass-made on Infiniti’s many products. Even though SBW continue to has complications these types of as superior price tag, immature technology, minimal person acceptance, small penetration rate, and so on., some automotive steering vendors and automakers are incredibly optimistic about SBW technology and are earning efforts herein. There will be a number of production versions utilizing SBW.

In June 2021, China Automotive Units, Inc. (CAAS) announced that Hubei Henglong Automotive Techniques Group Co. Ltd., a unit of the business, experienced bought 40{9f8850bc8f664a2ac1fdee25ffd85a3cdac362824700ab0655dbcffd0add5cb2} stake in Sentient AB, a Swedish automotive technology enterprise. Sentient has patents in the subject of wire command.

On June 5, 2021, Shanghai NASN Automotive Electronics Co., Ltd. produced a few new chassis-by-wire products, including SBW program remedies that assistance L3-L4 autonomous driving. 6 redundancy attributes make sure the typical operation of the steering program.

In 2020, Tesla prepared to set up a new crew in Austin, Texas, United states of america, accountable for motors, transmission systems and chassis systems. In the recruitment, Tesla needed candidates to have do the job working experience in “”SBW and brake/motor integration””. In the upcoming, Tesla may possibly be the to start with that used SBW technologies to Cybertruck battery-electric pickups.

In June 2021, Good Wall Motors launched Coffee Smart 2., geared up with an digital mechanical SBW program which is the initial domestic SBW technological innovation supporting L4+ autonomous driving. From the energy offer to sensors, controllers and actuators, it adopts a triple backup layout with the ASIL D safety level. It is expected to be officially place into commercial application in 2023.

(CAERI) has worked with Huawei, Baidu, Schaeffler and quite a few other businesses to jointly compile SBW and Brake Technique Communication Protocol Necessities and Exam Specifications, which is conducive to advertising the growth of SBW engineering and its software in smart automobiles.

At existing, the penetration amount of SBW in China is particularly low, and was approximated at .1{9f8850bc8f664a2ac1fdee25ffd85a3cdac362824700ab0655dbcffd0add5cb2} in 2020. In the subsequent number of several years, the penetration price will leap quickly, and it is anticipated to reach 15{9f8850bc8f664a2ac1fdee25ffd85a3cdac362824700ab0655dbcffd0add5cb2} by 2026. Meanwhile, the market place scale will gradually grow to RMB12.16 billion, with rewarding progress potential customers.

EPS is the key to ADAS functions, although SBW is one particular of the crucial systems for totally autonomous driving

The automotive steering program is carefully related to the enhancement of autonomous driving. At existing, EPS is the crucial to ADAS functions, serving distinctive stages of autonomous driving with common ADAS functions like APA, LDW&LKA and DSR. Nonetheless, in essence, the steering sign of EPS nevertheless comes from the driver, while the steering sign of SBW stems from the algorithm. Consequently, SBW can be entirely divided from the driver to handle steering as just one of the key technologies for totally automated driving in the future.

At existing, some automotive steering system companies have begun to deploy autonomous driving.

Nexteer Automotive can include L1-L5 autonomous driving by its EPS, significant-availability EPS, SBW and other merchandise portfolios. 32{9f8850bc8f664a2ac1fdee25ffd85a3cdac362824700ab0655dbcffd0add5cb2} of EPS orders signed by the enterprise are associated with L3-L5 ADAS/Advert functions. The ADAS-linked patents accounted for 22.7{9f8850bc8f664a2ac1fdee25ffd85a3cdac362824700ab0655dbcffd0add5cb2} of the company’s full in 2020.
