Abstract
A new circuit included to the racing calendar brings many challenges and expectations to drivers and race engineers. How to setup a racecar and the learning process about the racing line are important topics to be addressed. This work focuses on lap time simulations to deal with the introduction of a new circuit to the Brazilian Touring Car Championship known as Brasileiro de Marcas: a professional racing category of silhouette racecars resembling compact sedans. Due to the limited running costs of an entry-level racing team, tests and measurement of vehicle parameters are restrict. To deal with this issue, experimental data from previously race events helps to estimate the parameters. In this work, Monte Carlo method was used to estimate drag coefficient, drivetrain efficiency and tire/road coefficient of friction support by data acquired from a 2016 Toyota Corolla racecar. Two sets of data were acquired for this work: training data, from Ayrton Senna Circuit - GO, used to estimate the parameters, and Cristais Circuit – MG, used to validate the vehicle model.
