The Triple Hybrid Hydrogen Bus project comprises research and development, implementation and a test operation of a city bus with hybrid electric propulsion using hydrogen fuel cells. The mass distribution and the total bus mass are rather different from common buses. This is, among others, the reason for investigating the bus driving stability. In order to obtain a tool for dynamic analysis, multibody models of the bus were created. Verification of multibody models was performed based on the comparison of simulation results and experimental measurements focused on handling behaviour of the bus. To perform the simulations two approaches were used: the initial position of the bus multibody model at the beginning of the simulation of the manoeuvre depends on the bus motion trajectory and the initial position of the bus multibody model at the beginning of the simulation of the manoeuvre is set an equilibrium position.
