Our research group are studying a highly efficient small hybrid race car for the purpose of improving its dynamic performance. Since hybrid vehicles are equipped with multiple power sources with different characteristics, they can improve not only their fuel efficiency characteristics but also their dynamic performance by optimizing their operation. For this reason, hybrid systems combining ICEs and electric motors are beginning to be used in competition vehicles, where lap times must be minimized in order to win the competition. In this report, a lap time simulation including a nonlinear tire model and a two-track model that takes into account the forces of four tires are constructed to achieve a highly accurate simulation that is useful in the development stage of a small hybrid race car, and the simulation is compared with the previously used point mass model. Simulation results are compared to the traditionally used point mass model and actual logged data, and the validity of the two-track model is asserted.
