Analysis of automatically generated vehicle system control software in a HIL environment

This paper contains a description of a method and apparatus used for the comparison of a vehicle system control model with the automatically generated code which represents that model. The apparatus, referred to as hardware in the loop, consists of electronic control units, hybrid electric vehicle driveline components, dynamometers, and a Nighthawk super-computer. In the method presented, the model and generated code are executed concurrently in real-time. Output from the model can then be compared with the generated code in order to ensure that the code accurately represents the model.
