Team Description

Das TU Darmstadt Racing Team e.V. (DART) ist ein gemeinnütziger Verein sowie Hochschulgruppe der TU Darmstadt und hat sich der Förderung von Wissenschaft, Forschung und Bildung auf dem Gebiet des Fahrzeugbaus verschrieben.


Aktuell besteht der Verein aus ca. 45 aktiven Studentinnen und Studenten diverser Fachbereiche, insbesondere aus den Bereichen Maschinenbau, Elektrotechnik, Informatik und Wirtschaftsingenieurwesen. Zusätzlich verfügt der Verein über ein großes Netzwerk an Alumni, welche den aktiven Mitgliedern beim aktuellen Projekt mit Rat und Tat zur Seite stehen. Gemeinsam teilen wir die Begeisterung für Rennsport und Ingenieurwissenschaften. Durch die praxisnahe Vertiefung von studienrelevanten Themen sowie realitätsnahe Arbeitsbedingungen gehen die Mitglieder dabei nicht nur ihren Interessen nach, sondern bereiten sich aktiv auf ihren Berufseinstieg vor.

Ziel des Teams ist es, innerhalb eines Jahres ein Rennfahrzeug zu konstruieren, zu fertigen, in Betrieb zu nehmen, zu validieren und auf den Wettbewerben der Formula Student zu betreiben. Dabei gilt es, sich gegen die starke Konkurrenz aus dem In- und Ausland durchzusetzen. In der Vergangenheit hat der Verein dabei bereits an zahlreichen Wettbewerben teilgenommen, unter anderem in Hockenheim/Deutschland, Spielberg/Österreich, Barcelona/Spanien, Assen/Niederlande und weiteren kleineren Rennstrecken.

Das Besondere daran: Der Verein widmet sich insbesondere aktuellen Fragestellungen und Trends der Automobilindustrie. Bereits 2011 konstruierte das Team seinen ersten vollelektrischen Rennboliden und konnte dessen Technik und Antrieb seitdem stetig weiterentwickeln. Doch damit nicht genug: In der Saison 2017 verschrieb sich das Team zusätzlich dem autonomen Fahren und konnte mit dem myD2017 der Öffentlichkeit den ersten vollautonomen Rennwagen der Vereinsgeschichte vorstellen. Seit 2020 mit dem xi2020 wird anstelle der zwei Rennfahrzeuge nur noch ein Fahrzeug gebaut. Dieses ist elektrisch angetrieben und besitzt die Fähigkeit die Rennstrecke vollautonom oder mit Fahrer zu bewältigen.

Bei der Konstruktion des Rennwagens stehen sich wichtige Anforderungen wie Kosten, Zeit, Qualität und Innovation häufig in Spannungsfeldern gegenüber. Um eine effektive Schnittmenge aus diesen einzelnen Gebieten zu erreichen und schließlich ein erfolgreiches Projekt realisieren zu können, gliedert sich das Team in mehrere Teilbereiche und Hierarchiestufen. Im nicht technischen Bereich ist unsere Marketing-Abteilung angesiedelt. Die technischen Abteilungen sind Aerodynamik, Antriebsstrang, Batterie, Chassis, Elektronik & Informatik, Fahrwerk, Autonomes System und Vehicle Dynamics. Die verschiedenen Abteilungen haben je eine Abteilungsleiterin oder einen Abteilungsleiter.

Die Gesamtverantwortung für das Projekt übernimmt die Projektleitung, bestehend aus einem organisatorischen Teamleiter sowie einem technischen Teamleiter. Zu ihren Aufgaben gehört die Steuerung des Entwicklungsprozesses, die Projektplanung, das Projektmanagement, die Unterstützung der Abteilungsleitungen, die Koordination der Abteilungen und die Vertretung im öffentlichen Bereich.

Der Verein wird durch den Vorstand geleitet, welcher jeweils für eine Amtszeit von zwei Jahren gewählt wird. Zu den Aufgaben des Vorstandes gehören unter anderem die finanzielle und rechtliche Verwaltung und Vertretung des Vereins, sowie die Zieldefinition und Überwachung der langfristigen Vereinsentwicklung.

Info

Since 2005, DART Racing from TU Darmstadt has built cutting-edge race cars. A pioneer in electric racing since 2011 and driverless since 2017. This year, 45 students created our boldest car yet: powered by a 600 V accumulator, featuring our in-house inverter with integrated vehicle dynamics control, built to react faster, drive smarter, and push limits on every track. Oh, and fun fact: we’re also proud members of that elite club of top teams who’ve caused more than one rulebook change.

Info

So, we had the goal to hit into space. The universe is huuuuuge, you know. Real big and wide. So we build this tiny spaceship. Which can be operated by only one single person! It’s like a real spaceship, but much smaller. So it safes fuel for our environment. It`s driven by electricity and has four wheels. With motors in each single one. And there`s a gearbox in each of this tiny wheels. It`s f****** awesome! I tell you! The guys who build it are heroes!

Info

DART Racing is thrilled to be in Hockenheim for the tenth time! While building our car, the kappa2015, the team didn’t primarily focus on making groundbreaking changes to previous car designs, but instead on building upon them. Many parts have been redesigned to be easier to manufacture and flawed components have been reengineered. All changes contribute to an overall increase in performance and reliability.We are looking forward to a great competition at FSG 2015!

Car #101

Info

The TU Darmstadt Racing Team (DART) is now participating in the Formula Student Germany for the eighth time. Over 50 highly motivated students from various fields of study are working on this year’s car, the theta2013. By creating a completely new chassis and suspension, we decided to take the know-how from last year`s electrical powertrain and start with a new model. We have set our focus on a two-motor concept, in order to apply torque vectoring. The main component of our drive train will be a self-designed gear box, providing each wheel at the rear axle with the power of one motor. Following last year’s development of an aerodynamically optimized undertray, we are introducing a full aerodynamic package, including rear and front wings. Despite all these features our main aim was to reduce the weight of the car to minimum in team history. Therefore DART-Racing is looking forward to an interesting and hopefully successful Formula Student Germany competition.

Car #25

Info

DART-Racing is now participating at the Formula Student Germany for the seventh time. Over 35 highly motivated students from various fields of study are working on this year’s car, the eta2012. We set our focus on the electric powertrain with all its components, beginning with new cells up to the powertrain itself with keeping compromises to a minimum. We choose new materials to maintain our dedication to sustainability and reducing the carbon footprint, so we are able to stay focused on our concept without neglecting the static disciplines. As in the years before DART-Racing does stand for innovative and progressive design: developing a new undertray with a rear diffuser we open the aerodynamic chapter at DART-Racing. Through simulation and validation drives we are able to improve our car’s performance with least possible weight gain. DART-Racing is looking forward to an interesting and hopefully successful Formula Student Germany competition.
