Mercedes-Benz plans to launch a series production vehicle with Steer-by-wire technology – a first for a German manufacturer.
Instead of a mechanical connection between the steering wheel and the front wheels, as has always been standard, the steering maneuver is transmitted purely electrically via cable.
Mercedes Steer-by-Wire
No steering column, no direct contact, but a digital signal that quickly translates from the steering movement to the wheel position. A first Prototyp suggests that the debut model is the Eqs – a fully electric luxury class model.
For the driver, this means a completely new steering feel: more precise, more adaptable, less effort when maneuvering or parking. The system eliminates the need to grip the steering wheel and can be individually adjusted – depending on the model or even personal preference.
Technical implementation and driving experience
A Actuator on the steering wheel detects the movement and transmits the signal to the steering gear. There the wheel position is controlled, without mechanical connectionFeedback that would otherwise be directly noticeable via the tires is now generated based on the model.
Mercedes refers to the familiar “brand steering feel” that is artificially but precisely simulated. Coupling with the rear axle steering (steering angle up to 10 degrees) creates a combination of better agility, stability and Comfort. Unevenness in the road, which previously caused annoying feedback, is greatly reduced.
Advantages in everyday life and for vehicle design
Steer-by-Wire brings some practical advantages in the interior: The steering wheel can be made more compact and flatter, allowing more space, a better view of the display and easier entry and exit. In the future, this will also new seating positions be possible – especially in conjunction with automated driving on Level 3.
In addition, there is great potential for individualization: Vehicles can have different steering characteristics, and the elimination of mechanical coupling also allows for new Architectural ideas possible in the interior – for example for more relaxed travel or even gaming scenarios during breaks.
Security through redundancy
To ensure that everything is safe, Mercedes relies on a double protection: Both the signal paths and the power supply are redundant. In an emergency, the steering function is maintained by the rear axle steering and targeted braking interventions via the ESP – even without active steering wheel in front.
Precise sensors, powerful control units and a well-thought-out safety concept should ensure that the vehicle remains controllable at all times – even in the unlikely event of a complete failure.
Conclusion
With the move towards steer-by-wire, Mercedes is taking a major technological change An EQS without a steering column is more than just a gimmick—it could completely change the way we drive and how vehicles are designed.
