Bosch intends to bring steer-by-wire steering systems to the market in large-scale production by the middle of the decade. In a cooperation with the startup Arnold NextG, the automotive supplier plans to pool its development expertise and accelerate the systems’ market maturity.

The introduction of steer-by-wire systems in road vehicles has been discussed for many years, but all attempts have failed so far, and this despite the fact that steer-by-x technology would have enormous advantages for vehicle interior design. The hurdles to making such an electronic steering system sufficiently fail-safe even in the event of a power supply failure were apparently too great. As a leading supplier of electric steering systems, Robert Bosch GmbH recognizes the potential of these systems early on and is now driving their development. “We are registering a rapidly increasing demand for steer-by-wire systems. In the long term, we see a very large market in this area – by no means only, but also for the age of automated driving. We are pleased that, thanks to this cooperation, we are gaining further momentum in optimizing these systems,” says Dr. Gerta Marliani, Chairwoman of the Board of Management of Robert Bosch Automotive Steering GmbH. The goal of the partnership with the startup company Arnold NextG is to accelerate the realization of steer-by-wire solutions that are ready for large-scale production.

Arnold NextG specializes in the development of multiple redundant drive-by-wire systems with all interfaces for autonomous driving in small and very small series format. Founded in 2021, the company’s employees have more than 20 years of experience in road-legal drive-by-wire technology, giving it expertise in developing retrofit solutions for all by-wire applications. Thanks to the redundancy of Arnold NextG technology, experience has shown that authorities can issue system approvals more quickly and efficiently, allowing vehicles to be driven on public roads. Together, Bosch and Arnold NextG thus aim to accelerate the development of high-volume systems.

Steer-by-wire applications eliminate the physical connection between the steering wheel and the wheels. This opens up new freedom in the design of the vehicle interior, for example. In addition, the technology brings new safety features for vehicle dynamics control. For example, even small automated steering interventions can stabilize the vehicle without the driver at the wheel even noticing. In addition, the driving experience of a vehicle can be individually adapted to the requirements of individual vehicle manufacturers.

The use of a vehicle-independent and add-on capable drive-by-wire technology in the radically changing series vehicle platforms of the future is of crucial importance, especially for people with severe physical mobility impairments. As a result, it is possible that this target group will be able to benefit directly from developments in autonomous and automated driving, assistance and safety systems in the future.

“We have come to the conclusion that the Bosch steer-by-wire system has the best and most natural steering feel in the market. Bosch is one of the leading suppliers of electric steering systems and has a strong package of control technology and performance for later high-volume deployments. With the Arnold NextG technology, Bosch has a vehicle-independent development platform for retrofit solutions in the drive-by-wire sector, which makes it possible to validate data and requirements for large-scale production projects at an early stage of development. Together we can further develop this technology for series production,” says Kevin Arnold, founder and CEO of Arnold NextG, commenting on the cooperation.

By-wire systems stand for the electronic transmission of mechanical signals and impulses. They will also be a basic prerequisite for assisted and automated driving in order to bring the full strengths of individual functions to bear. The lane departure warning system, for example, can then correct the direction of travel without the driver feeling it on the steering wheel. The obstacle detection system can also avoid a sudden object without jerking the steering wheel and injuring the driver. In the future, the technology could even be used to steer wheels individually. This would make for smaller turning circles and make new vehicle concepts for local traffic and goods transport in cities conceivable.
