Abstract The paper shows how students used the modeling and simulation capabilities of the Matlab/Simulink to improve the control design of their winning FEIminetors car for the worldwide known Freescale Cup competition. Creating and simulating the model gives us a better understanding of the processes and almost bug-less transfer of the code to the embedded processor. Model was used also for the first estimation of a device controller. We also summarize our experiences with the competition organization. Keywords Freescale cup competition

1 Introduction The Freescale Cup [1] is a global engineering multilevel competition where student teams build, program and race an intelligent autonomous model car around a track. The fastest car to complete the track without going off the track wins the race. The competition aims to deepen student’s knowledge about the embedded control systems design. During the design phase students must tackle several Science, Technology, Engineering, and Math (STEM) related issues such as embedded microcontroller programming, closed loop control, modeling and implementation, as well as overall vehicle dynamics (physics). Soft skills are also trained through team collaboration, communication and project management [2]. Detailed car design documentation is an important part of the registration process, but unfortunately, it is not published anywhere and remains unknown for other teams. Newcomers have to search for some rarely published solutions or have to start from the scratch each year. In previous years some papers were published focusing on

specific aspect of the car design, e.g. the interface board design [3], or the line detection algorithm [4, 5]. Instead of detailed algorithm description, in this paper we try to show how to use a model based design instead of ad-hoc based and intuitive approaches for successful implementation of the controller algorithm. Brief introduction into the competition rules is sketched in the Sect. 2. In the Sect. 3 we show the electronic differential design, creation of the whole car model and the controller. In the last section we summarize our experiences and recommendations.
2 The Freescale Cup Competition Rules The Smart Car race was originally conceived in 2003 in collaboration with Hangyang University in South Korea and global company Freescale Semiconductor to increase student exposure to cutting edge industry tools [2]. For the first time, at the Hanyang University, they hosted 80 teams of students. Later the competition significantly succeed in China, where the number of teams quickly reached few hundreds—in 2008, China alone hosted over 1,800 teams from over 600
