This paper presents and exemplifies a novel methodology to perform simulation-based automated testing for verification of complex chassis-control systems. The methods are derived from computer-game principles and regard the system under test as an opponent that is defeated when the specification is violated. The methodology is demonstrated on an auto-coding implementation of a brake-blending function for a heavy vehicle, in combination with a simulation model implemented in Modelica. It is shown that a vast number of scenarios can be analyzed with moderate manual effort, and that results corresponding to high-coverage FMEA/FTA (Failure Mode and Effect Analysis)/(Fault Tree Analysis) analysis can be produced to verify system safety and robust performance.
