Formula Student and Formula SAE are student competitions where engineering students must develop a Formula type vehicle according to a series of rules. Regarding to the brake system, these rules determine some requirements that the cars must be in accordance.
This work deals with a performance evaluation of brake system of Formula type vehicle. First, a mathematical model was developed to achieve the balance of front and rear braking forces. This model takes into account the most important vehicle parameters that influence braking performance, as well as the tire/road friction conditions. Then, the results obtained from the model were compared against experimental data. During the tests the vehicle velocity, the lateral and longitudinal vehicle acceleration and the circuit pressure to the front and rear brakes were monitored. This mathematical model will be employed to development of brake systems to be applied to Formula type vehicle.
Finally, a second experimental test was employed to evaluate the brake system performance considering the vehicle operating in competition conditions.
The obtained results show that the mathematical model is suitable for brake system performance prediction. Moreover, the tests results show that the brake system is suitable under competition conditions.
