DUBLIN, Jan. 20, 2023 /PRNewswire/ -- The "Passenger Car Intelligent Steering Industry Research Report, 2022" report has been added to ResearchAndMarkets.com's offering.

Research on intelligent steering of passenger cars: The development of intelligent steering is accelerating, and it will be put on vehicles in batches in 2023

In September 2022, Geely and Hella jointly developed a series production-ready steer-by-wire (SBW) system which will be spawned from 2026.
In October 2022, NIO signed a strategic cooperation agreement with ZF. They will work together in the development of SBW products.
Toyota bZ4X featuring JTEKT 's SBW technology was put into mass production and launched in October 2022.

Schaeffler Technologies AG & Co. KG and Arnold Verwaltungs GmbH signed a basic agreement under which Schaeffler Technologies AG & Co. KG will acquire the remaining 10% stake in the joint venture company Schaeffler Paravan Technologie GmbH & Co. KG (Schaeffler Paravan) from Arnold Verwaltungs GmbH. Schaeffler's objective is to accelerate the development of integrated SBW systems for large-series automotive production, and also to use the market access gained through Space Drive applications to market fully developed volume production solutions.

From the perspective of supply and demand, the above-mentioned phenomena indicate that intelligent steering systems (including SBW systems) will gradually enter the consumer market. In 2023, the era of traditional mechanical connection will come to an end, while the SBW age may begin.

SBW systems will gradually replace electronic power steering systems.

With the development of intelligence, automotive chassis is evolving from traditional chassis to chassis-by-wire. For the sake of more accurate actuation, faster response and higher safety, high-level intelligent driving or autonomous vehicles require chassis systems to cancel the mechanical connection between actuators as much as possible, and use electrical signals to transmit instructions instead. At the same time, the system reliability and security should be ensured by additional redundant electronic components.

At present, electronic power steering (EPS) systems are the most advanced steering system solution for mass production. The fundamental difference between SBW and EPS is that the former removes mechanical connection between steering wheel and steering rod, and completely decouples steering wheel and steering mechanism.

After being widely used in high-level intelligent driving in the future, SBW can avoid interference with the driver's steering action and possible collision when the vehicle automatically turns in an emergency under control of ECU. Without a physical structure, SBW helps improve vehicle performance in terms of lightweight, responsiveness, and cockpit layout.

In chassis-by-wire, a SBW system is the core component that controls the lateral movement, and also one of important actuators of high-level intelligent driving. At present, SBW systems are still in the technical verification stage, let alone mass production. However, the absence of mechanical redundancy puts forward higher requirements for the reliability of electronic equipment and systems.

Before high-level autonomous driving is popular, there are still many challenges for the development of SBW. At present, EPS is still the mainstream of market, but SBW with smaller size and higher security will embody the future trend.

With the development of high-level autonomous driving and the synchronization of `electrification, intelligence, software and sharing`, the intelligent steering of passenger cars presents the following development trends:

Steering systems gradually evolve

As the core part of chassis, steering systems have gone through many mutations, such as mechanical steering systems, hydraulic power steering (HPS) systems, electric power steering (EPS) systems, redundant steering systems (RSS), steer-by-wire (SBW) systems, etc., gradually transforming from mechanization to electrification, then to intelligence.

The operating performance of steering systems has been improved, with higher levels of integration, electrification and intelligence. As the penetration rate of autonomous driving increases, the evolution to SBW systems will accelerate, and the upgrade of steering systems will match the level of autonomous driving.

From electric control steering, redundant steering to SBW

Amid the electrification of vehicles, intelligence has become a new driving force for the development of steering technology. In response to the requirements of autonomous driving, steering systems should feature higher safety and reliability to ensure that vehicles can enter a safe state or even continue to run safely when electrical systems fail.

Therefore, the industry is studying new technologies such as redundant EPS and SBW to guarantee system safety. Compared with redundant EPS, the most notable feature of SBW lies in zero mechanical connection between the steering wheel and the actuator, which brings about obvious advantages in cost control, design flexibility, functional richness and space layout.

As the core role of intelligent chassis, steering systems have high technical barriers. At present, German, American, Japanese and Korean steering giants still dominate the steering system market, especially redundant EPS and SBW segments. China is catching up with them. With the gradual maturity of China's intelligent automotive industry chain, some enterprises have mastered the core technology of steering systems and even SBW. They are expected to break the technical barriers and quickly seize the market share in the future.

SBW has not seen mass production, but domestic and foreign automakers and suppliers are deploying SBW vigorously

Toyota bZ4X has once again introduced the SBW technology to automotive market, providing the first experience for the mass production and application of SBW. It may make a major breakthrough in the development of SBW technology. Tesla aims to start mass production of its eagerly anticipated all-electric pickup truck "Cybertruck" in late 2023. Great Wall Motor's next-generation smart chassis also adopts SBW technology and it plans to start mass production in 2023. SBW will be verified by the market extensively.

At present, neither international nor local vendors have realized mass production of SBW technology. Amid high R&D investment by local enterprises, the vendors with leading positions in EPS and technology accumulation will perform better in SBW technology, and may surpass international counterparts soon.

2023 may become the first year of mass production of SBW

Toyota will launch bZ4X equipped with a SBW system in European market. This system has an additional standby power supply module, which improves the stability and diversity of system power supply with lithium batteries and capacitors based on a traditional generator and 12V power supply. In order to ensure reliability and safety of steering system, bZ4X has added electronic redundancy to power supply, communication bus, torque sensor, motor angle sensor, microprocessor, power drive and motor coil.

Toyota bZ4X has once again introduced SBW technology to automotive market, providing the first experience for the mass production and application of SBW. It may make a major breakthrough in the development of SBW technology. The technical achievements of SBW have taken shape, and mass production may start in 2023.
