The challenges of modern vehicle software development are mainly due to the increasing complexity and growing number of functions that lead to high costs and time expenditure for software tests. To meet these challenges, in this paper a method is presented that assigns software test cases to the test in-stances Hardware-in-the-loop simulation and vehicle. The main aim is an efficient and effective use of both instances. As vehicle prototypes are tremendously expensive, the focus is on the reduction of time for vehicle tests. A four-stage method assigns individual test situations to the correct instance by means of a utility analysis. For this purpose, the identification of technical aspects of testing is the first step. Afterwards, filtering and weighting of these aspects is necessary for specific use cases. Subsequently, the identification of test situations is the next step before assigning them to the correct test instance with the utility analysis. To prove the validity of the developed method the paper contains an application ex-ample, which evaluates 151 test manoeuvres with the method. The result is a drastic reduction of the time required for vehicle tests.
