AMG uses Silver and TestWeaver to develop DCT control software
December 1, 2010.
AMG has used Silver and TestWeaver
to validate and iteratively improve the control software of the AMG Speedshift
DCT for the AMG SLS super sports car.
AMG used Silver to virtually integrate and run the control software
on Windows PC in closed loop with a simulated vehicle model (Software in the loop, SiL).
The vehicle model was developed by QTronic, based on the
multi-domain modelling language Modelica.
For the automated test of the DCT control software, Silver was driven by thousands
of input sequences dynamically generated by the test case generator TestWeaver.
The inputs control the road properties, acceleration and brake pedals, PRND lever position,
and may also be used to activate dynamically (simulated) component faults, e. g. of sensors
or hydraulic valves. This systematic analysis of the possible system conditions is only
possible in simulation and is an important complement to the other test and quality
assurance measures, such as test benches and prototype test.
