How does the car behave if we change the tyre data?
Students put into practice at the AIC and the Olaberria circuit theoretical concepts of the subject of Vehicles.
Andoni Medina, professor at subject Vehicles, wanted the students to experience firsthand how a vehicle behaves if tire parameters are changed. Organized in two groups, the students felt the consequences of oversteer and understeer in the field: on the Olaberria circuit and on the AIC-Automotive Intelligence Center simulator, respectively. As Professor Medina explains, oversteer occurs when the drift angle (the angle formed by the wheel with its real speed vector) of the rear wheels is greater than the front wheels, and understeer occurs when the opposite is true (drift angle greater on the front axle than on the rear). Put into practice, this means that the car's yaw is higher than the one marked on the steering wheel when it oversteers, and lower when it understeers. Both phenomena are dangerous when they occur in excess, especially oversteer since it leads to a very possible loss of control of the vehicle and consequently to an accident.
The final goal of both practices, says Medina, "is that the students are able to calculate and predict how the car will behave based on the tire data.
Both exercises, which were well received by the university students, are part of an initiative of the AIC training unit whose goal is to bring companies and universities closer together. "One of the challenges of the AIC, Open University, is for there to be a real collaboration between organizations and universities. In other words, companies propose a series of challenges and projects that are applicable to their day-to-day work and that they will implement, so that students can carry them out, in this case, in a subject", explained Gonzalo Garrido, head of Communication at AIC.Olaberria AIC, Automotive Intelligence Center
