Neue Technik: Steer-by-Wire-Lenkung: Autos werden jetzt zu Kurvenmeistern

In San Francisco, a steep Lombard Street is causing trouble for tourists and locals alike as they navigate the famous eight tight curves. However, it is precisely this unique feature that attracts visitors, who come to experience the city's most winding road. Even those new to San Francisco often add the Lombard Street to their bucket list, as it provides an unforgettable driving experience despite the challenging maneuvers required.

The Los Angeles Times reports that automobile manufacturers are turning to an innovative technology called Steer-by-Wire, which promises to improve steering performance in such situations. By replacing the mechanical connection between the steering wheel and wheels with cables and electric motors, the translation becomes flexible and adaptable.

Luc Diebold, a developer at Mercedes in cooperation with ZF Friedrichshafen, explains that the system adapts the translation to the speed, making it weaker at low speeds and stronger at high speeds.

The new EQS model from Mercedes is the first in Europe to feature this technology, showcasing a significant improvement in maneuverability through reduced turning radius. When driving the EQS through the Lombard Street, drivers barely notice the tight turns, as the car glides effortlessly through the eight tight curves. The rear axle steering provides exceptional maneuverability, making the five-meter-long limousine feel more like a smaller C-Class.

Although the Steer-by-Wire system is primarily a technical challenge, Mercedes-Benz emphasizes safety by implementing double redundancy and backup batteries in critical components. Additionally, sensors at the wheels and steering wheel allow drivers to feel the road conditions even without a mechanical connection, such as the sensation of cobblestones or channel barriers.

Preliminary testers of the Zeitschrift magazine admit that it took some time to get used to the new driving experience, but they believe it is well worth the adjustment.

Besides Mercedes, other automakers are also incorporating the Steer-by-Wire technology. Peugeot plans to introduce a similar system in their upcoming 208 model in 2027, and Tesla has already implemented the technology in their Cybertruck. Chinese automakers such as Nio and Lexus are also utilizing the technology in their vehicles, showcasing its growing popularity across the globe.
