Mathematical model of the start of a racing vehicle on an unpaved surface
Čech, Tomáš ; Porteš, Petr (oponent) ; Svída, David (vedoucí práce)
This thesis describes the process of designing a mathematical model of a launch control system in Simulink for a Super Buggy racing prototype vehicle driving on an unpaved surface. The rules of the Super Buggy class severely limit the resources allowed to be used for vehicle control, mainly in terms of sensors. To be able to design the control system even around those limitations, a bespoke measuring system was created to garner data necessary for building a virtual vehicle twin of the Super Buggy prototype. It was then used, in conjunction with a separate custom-developed algorithm, to simulate a baseline ideal acceleration run, from which more data could be obtained. This data was finally used to create a baseline for the launch control system to follow, which would eliminate the need for the sensors prohibited by the rules. This solution was tested using the virtual vehicle in terms of straight-line acceleration performance against a wide-open throttle driver input and a variety of artificial driver inputs in the surface conditions it was designed for. Furthermore, its independence of gear shift timing was tested, in addition to its performance in friction conditions different from the ones it was designed for. In chapter 13 and the conclusion, the possible future implementation of the launch control system, its overall potential and shortcomings, and the suggestions for improvements are discussed.
