Lexus has effectively addressed the challenges associated with Tesla's controversial yoke steering by introducing a more advanced steer-by-wire system in its RZ 450e model. Tesla's yoke, which faced criticism for its impracticality, especially in low-speed scenarios like parking, requires drivers to awkwardly reposition their hands during sharp turns due to its fixed, non-rotational design.
Lexus, however, resolved these issues with a fully electronic steer-by-wire system that eliminates the traditional mechanical connection between the steering wheel and the wheels. This allows Lexus to implement a variable steering ratio, which adjusts based on the car's speed and the driving situation. For instance, at lower speeds, the system can achieve a full steering lock with just 150 degrees of rotation, making tight maneuvers much easier. At higher speeds, the system provides a smoother and more stable driving experience by requiring less input from the driver.
This design not only makes the yoke more user-friendly but also enhances safety by incorporating multiple layers of redundancy. Lexus' system is equipped with dual motors, sensors, and backup power supplies, ensuring that the vehicle remains controllable even if part of the system fails.
The steer-by-wire technology also allows for customizable feedback, offering a more refined driving experience that can filter out unwanted vibrations while still providing essential road feel, catering to different driver preferences.
Overall, Lexus' approach addresses the key drawbacks of Tesla's yoke while adding significant technological advancements that could set a new standard for future steering systems in EVs.
