The article identifies the challenges during the system and specifically the software development process for safety critical electro-hydraulic control systems by using the example of the hydrostatic driveline with a four speed transmission of a feeder mixer. An optimized development approach for mobile machinery has to fulfill all the requirements according to the Machinery Directive 2006/42/EC, considering functional safety, documentation and testing requirements from the beginning and throughout the entire machine life cycle. The functionality of the drive line control could be verified in advance of the availability of a prototype by using a “software-in-the-loop” development approach, based on a MATLAB/SIMULINK model of the drive line in connection with the embedded software.
