Electrification of bus and truck: An easy task with the proven ELFA system

Drive systems for commercial vehicles

Safe. Efficient. Flexible. - ELFA keeps your customers moving, no matter where they are

Growing mobility demands and increasing transport of goods are the main drivers of a collapsing traffic situation and health risks we are facing today.  ELFA, the innovative drive system from Siemens, is a key component in meeting these complex challenges. With Siemens ELFA system, OEMs can design their specific drive train configuration. Operators enjoy profitable, energy saving as well as emission free transport of people and goods.  In a word: ELFA - the electric drive system that suits all your needs.

Requirement Engineering in model-based design (MBD) approach

The increasing complexity in vehicles and a multitude of interdependencies between individual subsystems today require consistent system thinking. This also applies to the powertrain and peripheral components. 

 

In the approach of model-based design, a virtual model of the vehicle system is created from information in close exchange with our customers and from environmental factors.  All interdependencies and system requirements are then broken down to component and software level.

 

Realization of the components is accompanied by numerous simulations, tests and detailed analyses. Tools such as Matlab©/Simulink© and methods such as hardware-in-the-loop are used. Comprehensive tests in our own system test facility as well as in the vehicle prototype with our technical experts and engineers on site are standard at Siemens.     

 

Changing requirements, one constant - Siemens ELFA.
