Steer-by-Wire steering systems
efficient vehicle control via cable and electrical signals

What once began as a concept is now an impressive reality that is constantly evolving. The transmission of steering signals via cables instead of mechanical connections - steer-by-wire. As a technological market leader, we have successfully implemented numerous steer-by-wire steering systems for industrial vehicles and special applications over the last 50 years.

Our latest generation of safety steering computers (control units) has been developed in accordance with ISO 26262. This means that vehicles approved for use on public roads can also be equipped with our steer-by-wire steering systems - a significant milestone in the development of steer-by-wire technology.

Experience the future of steering systems with MOBIL ELEKTRONIK - especially with our reliable EHLA® steering systems, which set new standards in vehicle steering.

Benefits of steer-by-wire steering systems

Steer-by-wire steering systems are not only the basis for autonomous vehicles, but also already offer considerable added value compared to conventional steering systems. Have a look yourself:

  1. Highest level of security through redundant system concepts
  2. Reduction of complexity through standardization
  3. Increased safety through the possible interaction of assistance systems

Our patented EHLA® steer-by-wire steering system –
for superior driving dynamics and precision

Experience the future of vehicle steering with EHLA® - our revolutionary steer-by-wire steering system. No more mechanical steering connections, instead wired precision and maximum safety. MOBIL ELEKTRONIK makes it possible!

The right EHLA® system for every vehicle

Every vehicle is unique, even if the geometry differs only slightly. Our EHLA® steering systems are designed to be flexible. Important control variables of the steering systems are adapted to the different geometries using parameters. When designing your steering system, we rely on proven standard components that are already successfully used in series production.

ISO-certified process

Regardless of the number of axles to be controlled, a wide range of different EHLA® steering systems is available to you. An ISO 26262-compliant process for our high-quality electronic components is one of the basic principles of our development. We maintain the greatest possible flexibility in order to fully meet your individual customer requirements in every respect.

Highest safety standard: ASIL D

It is the responsibility of the vehicle manufacturer to carry out a comprehensive hazard analysis and risk assessment. This results in the specific safety requirements for the EHLA® steering system. With the latest generation of our modern safety steering computers, safety functions up to the highest standard ASIL D can be implemented and guaranteed.

Functional Safety

The requirements of ISO 26262 often present our customers with major challenges. With our expertise in this area and our more than 50 years of experience in the design of EHLA® steering systems, we are happy to assist you. Do not hesitate to ask us for a workshop on topics such as functional safety, HARA (Hazard Analysis and Risk Assessment) and Safety Concept.

Cyber Security

Ensuring security in an increasingly networked world is undoubtedly the big issue of the future. This also applies to a large extent to the automotive industry. Vehicles are no longer just simple means of transportation, but high-tech computers on wheels, vulnerable to potential hacker attacks. Every vehicle must be able to withstand cyber attacks in order to ensure the safety of all road users.

The good news is that the steering systems from MOBIL ELEKTRONIK also meet the highest cyber security requirements.
