This thesis aims to develop a quasi steady-state lap time simulator for a Formula Student electric prototype developed by Squadra Corse PoliTO. The idea is to create a tool that helps the team to evaluate the influence of the main parameters of the vehicle on the performance and define the race strategy in terms of a trade-off between lap time and energy consumption. In the following chapters, a point-mass quasi steady-state simulator is developed. The vehicle is modelled as a point-mass with longitudinal and lateral friction coefficients, longitudinal and vertical aerodynamics, and with an electric powertrain composed of motors, inverters, and a battery pack.
