Rivian appears to be developing a wire-based steering system.
In the ever-evolving world of automotive technology, a new concept is making waves – Steer-by-Wire (SBW). This innovative system replaces traditional mechanical linkages between the steering wheel and the wheels with electronic actuators.
Tesla, with its groundbreaking Cybertruck, was the first to implement a fully committed SBW system in mass production. Now, Rivian, another trailblazer in the electric vehicle (EV) sector, is potentially working on a full SBW system for its vehicles.
Rivian, based at its Irvine, CA headquarters, has posted a job listing for a Senior Staff Technical Program Manager, Steering Actuator System, suggesting a focus on developing SBW technology. This move could lead to the implementation of SBW in Rivian's upcoming models, including the R2 and R3, with the R2 in late stages of development.
The R1 model, Rivian's flagship vehicle, has recently received a big refresh. The job posting mentions full cradle-to-grave ownership of the SBW subsystem, indicating Rivian's commitment to this technology.
Besides Rivian and Tesla, several other companies are heavily involved in SBW technology development and implementation. Nio, the Chinese EV maker, uses SBW technology supplied by the German supplier ZF in its ET9 sedan. ZF, a major automotive supplier, is also a key player, with customer orders for steer-by-wire systems in Europe being processed.
Lexus has also dipped its toes in SBW, typically using partial SBW such as mechanical front-wheel steering combined with rear-wheel steer-by-wire. Other notable players include General Motors, Honda, Cruise, Infineon Technologies, and even luxury brands like Rolls-Royce and Hummer.
The benefits of SBW are numerous. It allows for more customizability, reduces mechanical complexity, and adds speed-sensitive variable steering ratios. However, there are also disadvantages, such as a reduction in steering feel and the need for regulatory updates.
