Abstract: To subject a test object during a test run on a test bench to real environmental and/or surrounding conditions, particularly thermal conditions, it is provided that at least one temperature is measured at a measurement point as a measured variable during the test run on the test bench. At least one test object component of the test object is subdivided in a number of segments. The thermal interaction of at least one segment with the environment of the vehicle is simulated during the test run by a thermal simulation model of the simulation model. The thermal simulation model calculates the segment heat flow that is supplied to or dissipated from the at least one segment. This segment heat flow is adjusted as a function of the measured temperature at the test bench on at least one segment by means of a number of heat flow actuators.
