Simulation eines Elektrofahrzeugs mit zweistufigem Getriebe

This thesis deals with the simulation of different kart propulsion and gear transmission systems respectively to demonstrate different setups. A real driving cycle was extracted form GPS data, mainly for its position and velocity. Based on this data, the individual components for the simulation model were chosen and adapted to meet the key data taken from the reference vehicle. The aim was show the difference between the internal combustion engine and the electric machine with one- or two-gear transmission. The energy storage system and the electric machine with similar performance as the internal combustion engine were integrated into the full vehicle simulation model. To compare the different approaches, adequate key data were selected, namely the acceleration time and the energy input. The three models, internal combustion engine, electric drive with one-gear and the electric drive with a two-gear transmission were compared according to the mentioned parameters. It is shown, that by using an electric drive you considerably reduce the amount of needed energy. The acceleration time is also reduced and by using a two-gear transmission system the drive performance increases additional.
