How the software-defined vehicle trend is driving innovation in chassis features

Steer-by-wire technology eliminates mechanical steering connection, offering benefits for manufacturers and drivers.

Steer-by-wire technology (SbW) eliminates the mechanical connection between the steering wheel and steering rack, relying solely on electronic communication. It offers numerous benefits for manufacturers and drivers, including the ability to produce a “dry” chassis without hydraulic fluid. It also opens possibilities for semi-autonomous safety systems and alternative steering controls. The systems are fully redundant, ensuring backup functionality in case of hardware or software failures. SbW is a crucial component for autonomous vehicles, and we can expect to see more examples of it in the coming years. Its adoption in mainstream vehicles, such as the Toyota bZ4X and Lexus RZ 450e, is a sign of things to come.
