To begin a simulation, a matlab script based program loads the vehicle parameters, a driver. This simulator will be built using matlab simulink, because this software package supports all three parts of the simulator, namely the user input, the vehicle model and the visualization.
By using lap time simulation we get a decisionmaking basis for different concepts aerodynamic setups amount of accumulator capacity transmission ratio models are simplifications, but they are very helpful. Paco sevilla, of tu fast formula student team, and christoph hahn, of mathworks, explain how lap time simulation can be used to compare vehicle concepts in the early design stage.
