Vehicle simulation is a very important part in the design and development of powertrains groups. To precisely simulate the powertrain running status, many commercial software products are applied into the development of control strategy. AVL Cruise software allows the simulation of the vehicle driving performance, fuel consumption and emissions. In 2017 the European Union intends to adopt a unique normalized cycle World Harmonized Light vehicles Testing Cycle – WLTC, more representative for the real traffic, with more aggressive acceleration and patchy, with higher maximum speed, with a greater length of time. A conventional powertrain will be created in the AVL Cruise software and simulate vehicle driving performance, fuel consumption and emissions over the new WLTC test cycle. In order to achieve this, the WLTC test cycle will be written and adapted to the Cruise simulation software for the proposed powertrain. A conventional powertrain, with a unique power source represented by an internal combustion engine will be considered for the sake of simplicity. The results will be useful for the automotive specialists and car manufacturers.
