dc.description.abstractThe autonomous driving industry is currently growing rapidly due to the large demand created by our society. Formula student, the largest student engineering contest in the world, assesses the automobile production by developing and competing with formula cars. Formula student driverless is one of the branches of the large competition, Chalmers University of Technology is one of the represented universities with two attending teams. The role of this bachelor’s group is to be a part of the 2019 Chalmers formula student driverless team and maintain and develop the hardware of the car. The thesis is separated into three different sections, where each section describes a problem solving process. The sections are: the aerodynamic package, the steering actuation and the computer case. The aerodynamic package was designed for a formula car driven manually at a different speed than the current autonomous system. Therefore, an analysis of the current aerodynamic package was performed. The results were generated through simulation methodologies and it was decided that the aerodynamic package was sufficiently valuable to the car’s performance. To analyse the steering actuation, tests were made comparing sent steering requests to readings of potentiometers mounted on the linear actuator and on the steering rack. The conclusion was that the steering system had drawbacks such as play and complexity, but it was kept since it is robust and the time needed to rebuild the system could not be justified. The computer case’s function is to protect the computer from water and dust while also enabling cooling of the components. The case created in 2018 was deemed inadequate for the competition. Therefore a new case where developed to replace the old one. Different concepts were generated and condensed into a final prototype which was manufactured. The final product fulfilled the requirements to confine the computer in a water and dust proof casing. By implementing a quantitative and qualitative analysis of the three projects, a conclusion was drawn deciding that the aerodynamic package was the most valuable project to score points in the formula student driverless competition. All things considered, the entire result generated an advantageous score to the competition.
