Testing Platform for Hardware-in-the-Loop and In-Vehicle Testing Based on a Common Off-The-Shelf Non-Real-Time PC

Abstract—The rapidly growing amount of software in em-bedded real-time applications such as Driver Assistance Func-tions in cars leads to an increasing workload in the field of software testing. An important issue is thereby the timing behavior of the software running on the target hardware. The timing behavior of the Driver Assistance Functions is usually tested on real-time capable Hardware-in-the-Loop platforms as well as by in-vehicle tests, where the timing behavior is evaluated with the help of data loggers. Both, the data loggers and the Hardware-in-the-Loop platforms are mostly custom-made, proprietary and in consequence expensive. Moreover, many software developers usually have to share few instances. Existing inexpensive solutions show deficits in their real-time capabilities, which means for Hardware-in-the-Loop platforms that the real-time behavior cannot be guaranteed and for dat
