Abstract in different language:	In the development of a road vehicle such as a bus, the input data for the assessment of the fatigue life of the body and other mechanicalparts of the vehicle are gradually refined. In the initial phase of the development of a new vehicle, so-called design stress spectra are used. It is necessary to estimate the design spectrum parameterscorrectly. At the vehicle's prototype testing phase,the so-called service stress spectracan be evaluated. It is essential to determine the characteristic operating modes of the vehicle and to record representative stress-time historiesof the critical sections of the construction nodes and vehicle components. Accelerated driving test of fatigue life can be performed on special test routes. The acceleration of such a fatigue test is dependent on the test track composition. The paper generally describes the methodology of such a process and demonstrates it using unique real-time data acquired during the development of abus.
