DUBLIN--(BUSINESS WIRE)--The "China Automotive Steering System Industry Report, 2021" report has been added to ResearchAndMarkets.com's offering.
The biggest difference between SBW and EPS is that the former removes the mechanical connection between the steering wheel and the rack and uses ECU to transmit commands instead. SBW features fast response, flexible installation, lighter weight, and improved collision safety.
SBW technology was proposed as early as 1950. After decades of development, it has now been mass-produced on Infiniti's several models. Although SBW still has problems such as high cost, immature technology, limited user acceptance, low penetration rate, etc., some automotive steering vendors and automakers are very optimistic about SBW technology and are making efforts herein. There will be a number of production models using SBW.
In June 2021, China Automotive Systems, Inc. (CAAS) announced that Hubei Henglong Automotive Systems Group Co. Ltd., a unit of the company, had bought 40% stake in Sentient AB, a Swedish automotive technology company. Sentient has patents in the field of wire control.
On June 5, 2021, Shanghai NASN Automotive Electronics Co., Ltd. released three new chassis-by-wire products, including SBW system solutions that support L3-L4 autonomous driving. 6 redundancy features ensure the normal operation of the steering system.
In 2020, Tesla planned to establish a new team in Austin, Texas, USA, responsible for motors, transmission systems and chassis technologies. In the recruitment, Tesla required candidates to have work experience in `SBW and brake/motor integration`. In the future, Tesla may be the first that applied SBW technology to Cybertruck battery-electric pickups.
In June 2021, Great Wall Motors launched Coffee Smart 2.0, equipped with an electronic mechanical SBW system which is the first domestic SBW technology supporting L4+ autonomous driving. From the power supply to sensors, controllers and actuators, it adopts a triple backup design with the ASIL D safety level. It is expected to be officially put into commercial application in 2023.
At present, some automotive steering system companies have begun to deploy autonomous driving.
Nexteer Automotive can cover L1-L5 autonomous driving through its EPS, high-availability EPS, SBW and other product portfolios. 32% of EPS orders signed by the company are involved with L3-L5 ADAS/AD functions. The ADAS-related patents accounted for 22.7% of the company's total in 2020.
In terms of autonomous driving and advanced driving assistance, JTEKT develops and produces EPS that meets the national standard ISO26262 for automotive functional safety. By dual-systemizing the torque sensor that monitors the driver's operation and the motor drive that provides the steering assist torque, the sustainability of EPS is improved. In addition, JTEKT has developed SBW technology for autonomous driving above L3.
