Mobil Elektronik steers off-highway vehicles to safety


Mobil Elektronik is ensuring off-highway vehicles can steer safely in extreme applications.

Having fundamentally revised the core component of the steering function – the safety steering computer – the company’s EHLA electronic system is helping construction and agricultural vehicles to cope with the challenging circumstances they regularly encounter.

Thanks to the ISO 26262-compliant development and the completely new hardware and software architecture, a security level up to PL e/AgPL e/ASIL D can be achieved, which is important for meeting upcoming increased safety requirements.

The hardware architecture of the system is based on dual-core processor technology. Furthermore, Steer-by-Wire applications for front axle steering with approval for public

road traffic can also be implemented with this safety steering computer.

The housing has also undergone a fundamental redesign. The new component has an automotive-compliant housing with ingress protection marking IP6K9K. This results in very flexible installation options – even outside the cabin – where extreme conditions prevail due to dirt, water and salt.

A sophisticated temperature management and the use of automotive-compliant components ensure a particularly long product service life. The features of the new safety steering computer are also impressive.

There are three CAN interfaces available as well as a USB interface for diagnostics and parameterization via the diagnostic tool PCSnext developed by Mobil Elektronik. The inputs and outputs are freely configurable so that the new safety steering computer can be used flexibly for different steering applications.

The well-established integrated control panel for internal diagnostics is optionally available. This provides the steering system with a constant diagnostic capability, even if the external diagnostics tool PCSnext is currently not available – a useful addition if the vehicles are operated far away from truck repair shops.

In addition to this new safety steering computer, Mobil Elektronik will also be presenting further innovations and solutions at Bauma 2019 at Hall A3, Booth 115.
