So you are interested in applying for CFS23? Great!
Formula Student is the largest engineering competition in the world for students. Its aim is to improve engineering education by providing hands-on experience from a project where you can take your own concepts and designs from the drawing board all the way to a physical prototype. Every participating team designs, manufactures and tests their own vehicle. At Formula Student competitions the performance of the vehicle and the knowledge of the team is tested. There are dynamic track driving events such as endurance and acceleration, and static events where the cost of manufacturing, the vehicle's design and the business idea of the project are presented to judges.
CFS23 will build a 4wd electric vehicle that can be driven both by a human and an autonomous system. The car will be a continued development of the current CFS22 car Hilbert. Selected subsystems will be carried over, but rest assured, there will be plenty left to work on. The aim for CFS is to go to two Formula Student competitions each summer. Our hope is now that you want to take over the mantle and ensure that CFS remains a competitive Formula Student team! It should be stressed though that it is up to each new team to decide upon an ambition level that suits them. The project exists for educational purposes and the main priority is that it should be a great learning experience.
Give the videos below a look to gain some motivation!
CFSs aims to recruit a new team consisting of 35-40 Project Engineers and these team members also take the course TME047 (15 ECTS). In addition CFS recruits 5-10 Trainees. The Trainee role is an introductory position where you can learn about the project and it forms a great starting point for participation as a team member the following year. To be a Trainee does not give any credits. Typically the Project Engineers are first year Master's students and Trainees third year Bachelor students, but these are not strict requirements as seen below.
The position as Project Engineer in TME047 is open for
3rd year Bachelor students. (But please note that CFS is a Master's course. We will ask you to verify with your program coordinator that you can take the course as a part of your Bachelor)
1st year Master's Students.
2nd year Master's Students (if not doing a Master’s thesis alongside CFS)
Exchange Students (If you stay for a full year and don’t do a Master’s Thesis alongside CFS)
The position as Trainee is open for
1st-3rd year Bachelor students
The course TME047 Chalmers Formula Student gives 3 credits during the autumn and 12 credits during the spring. It is a strong recommendation to only study one course in parallel with CFS during the spring periods as the manufacturing phase is very time demanding. You cannot combine CFS with full time Master thesis work as stated above. Participation in CFS is a full year commitment that requires a lot of time and dedication, much more than the 15 ECTS indicate, but it also gives a lot in the form of experiences and friendship. You get back what you put in.
What are we looking for?
We would like to recruit team members from all over Chalmers. So whether you study architecture, entrepreneurship, computer science, electrical or mechanical engineering, we welcome and encourage you to apply. While we do appreciate previous experience and ask about it during application, that is also what you are here to get. Few of the team members have built a formula style race car before, so don’t let a lack of experience in this area stop you from applying.
Below you will find a description of the different areas of responsibility (subgroups) within the team. You can select your application priorities between these areas in the application form. As CFS23 will continue to develop the CFS22, car the scope for re-design will vary between the different subgroups, but we recommend that you fill out your priorities based on your interests, and we can discuss the work scopes in more detail during the interviews.
Business & Management
This group has responsibilities in two different areas. It is responsible for the team’s partner relations and external communication (e.g via social media and events) and it typically takes on a leading role in the team’s internal organization and management. During competition, members of this group are often responsible for two static events, the first one being the BPP (Business Plan Presentation) where a business case based on the CFS23 car should be pitched to potential investors (think Shark Tank), and the second event being the Cost Event where a production cost and plan for the vehicle should be presented. The Cost Event is thus very well suited for students with an interest in industrial economics. As social media and communication is a central part of the responsibilities for this subgroup, interest and knowledge in photography, video making and web design are great additions.
This subgroup is responsible for the frame structure and driver ergonomics. CFS typically builds a carbon fibre monocoque which requires work in surface CAD modelling and the design, simulation, test and manufacturing of carbon fibre sandwich layups and parts.
This subgroup is responsible for the suspension assemblies, brake and steering systems and the mechanical aspects of vehicle dynamics. The mechanical systems under this subgroup are built from a large number of parts and require mechanical parts design using CAD and structural simulation tools. The vehicle dynamics aspects are designed using specialised simulation tools for lap time, vehicle manoeuvre and suspension kinematics performance.
This group is responsible for the design of the aerodynamic devices (e.g. wings) on the car to ensure the best possible aerodynamic performance as well as ensuring that the cooling air flows are sufficient over the radiators and in the battery. The work typically involves the structural and aerodynamic design of carbon fibre wings including structural simulations and fluid dynamics simulations (CFD). Some years we have been able to test the car in Volvo car’s windtunnel, but this is pending on the availability of a slot and this cannot be guaranteed.
The CFS23 will have an electric powertrain, but also electric powertrains require mechanical design. This group is mainly responsible for the design of gear boxes, cooling system, battery casing and mechanical design aspects of the electric motors.
This subgroup is responsible for the high voltage drive system of the car. This includes for example the high voltage aspects of the battery (e.g. pre-charge circuit), motor control and the overall design of a High Voltage system and the safety requirements that comes with it. Before the powertrain goes into the car it will go through extensive benchtesting during the spring. The main focus for this group in the CFS23 project is the continued development of a power electronics unit for motor control developed in-house.
Low voltage electronics
The low voltage electronics group is responsible for the car’s control, communication and monitoring systems. The LV subgroup works with electronics hardware, low and high level software and control systems. As the LV group is responsible for many different things, it will be a large group of people that will be split into smaller working groups to operate efficiently.
On the hardware side the group is for example responsible for the selection of sensors to acquire log data, the design of customised printed circuit boards (PCBs), the vehicle’s safety shut down circuit or selection of cameras for the autonomous system. The physical low voltage system from a previous car is shown in the image below. On the software side both low and high level programming is needed. Tasks include for example the programming of microcontrollers on PCBs to take actions based on input from sensors and driver or continued development of the autonomous driving system. Knowledge of control systems is needed both for the autonomous system and for driver aids such as wheel slip control and torque vectoring. The latter is a system that distribute the drive torque between the four driven wheels depending on the given cornering situation with the aim to optimise cornering performance and minimise laptime.
