UCI FSAE Electric raceteam is made up of multiple teams working together to complete one car. Take a look at all the teams that make our project happen.
The Aero-Body team works on the design of the final body and aero package that will be implemented on the vehicle.
Design aerodynamic body and an aero package that will increase downforce
Assist Telemetry subteam with sensor placement
The batteries subteam develops the physical housing and the wiring for the batteries that power the vehicle. The main design objectives are to ensure structural integrity of the enclosure while maintaining lower weight, proper cooling of the cells, and maintainability of the electrical system housed inside
Design: CAD different packaging designs for the battery cell enclosures, Finite Element Analysis, Flow analysis for cooling, and electrical system design with wire management.
Manufacture: Waterjet, Sheet Metal Bending, Riveting, Tig Welding, Cable Management
Verify: Weigh Box, Mount in Car, Test Low Voltage and High Voltage systems with Electrical
The chassis is the physical structure of the car: it is the skeleton that mounts the suspension, powertrain, batteries, and everything else that makes up a running car. The chassis subteam’s objective is to design, manufacture, and verify a lightweight but robust chassis that mounts the other subsystems with proper triangulation.
Design: CAD a design in Solidworks, do Finite Element Analysis, and consult with other subteam leads for packaging their subsystems.
Manufacture: Profile and bend metal tubing, make jigs and align tubing, and weld it all together.
Verify: Check alignment, weigh the chassis, do torsional rigidity tests, and check with other subteams that their subsystem components fit.
Design a system of programmable microcontrollers and sensor arrays for vehicle controls, including fault detection, Throttle & Brake Plausibility, and a closed-loop Torque Vectoring Algorithm to the motors.
Program microcontrollers to a specific task
Set up data interfaces, including CANBus, Serial Peripheral Interface, I2C, and UART
Wire, mount, and calibrate sensors, including: IMU; Tire Temperature, Wheel Speed, GPS
Provide system feedback to our central control module for torque vectoring
Collaborate with Electrical in designing Interface boards for our microcontrollers
Provide wireless data transmission for our Telemetry team
The electrical subteam works on the electronic hardware components in the car that tie different systems together in order to run all operations.
Develops Electrical systems built of critical safety systems, similar to that of modern electric cars, and microcontroller systems. These systems are packaged into modules and are developed into PCBs.
Provides hands-on PCB design, SMD soldering electronics development, electronics troubleshooting, DFM (Design for Manufacturability) review, FMEA (Failure Mode Effect Analysis), and System Design. It can provide an opportunity for PCB development, Electronics Engineering, Electrical Engineering, and Systems ARchitecture Development
The Human Interface subteam is responsible for creating systems for humans to control and interact with the car--whether that be: creating mechanical systems to receive physical inputs from the driver and translate them to physical outputs of the vehicle, creating enclosures that allow our engineers to easily interact with/maintenance electrical components, or designing a seat and harness system to safely and comfortably seat the driver. The Human Interface subteam creates systems that allow for the car to be safe, and controllable.
Communication and Collaboration: The designs of the human interface team interact/interface with almost every system on the car, so multidisciplinary communication is essential for any Human Interface designer.
Design: Using knowledge of engineering principles and problem solving to create a component/assembly to address a need for the vehicle. Involves research, analytical thinking and problem solving, the use of CAD software, FMEA, etc.
Rapid Development: Since human interaction is an essential factor in creating a successful human interface design--rapidly developing prototypes and components is crucial to the success of any human interface design.
Testing: Testing is not only necessary to verify a design, but is also used by human interface engineers to inform their designs.
MARKETING AND OUTREACH
The marketing team handles all outreach materials in order to show industry what the UCI Electric Race team is accomplishing.
Develop promotional materials
Communicate with sponsors
powertrain team works on developing an efficient way to convert electrical power obtained from the batteries into mechanical power which drives the vehicle.
Designing, manufacturing, and testing housings for components which deliver torque to the wheels.
The suspension’s main purpose is to keep the wheels planted to the ground at all times. Furthermore, we seek to improve handling through designing, manufacturing, and testing our own subsystem.
Design: Design the suspension geometry that works well with our chassis and behaves appropriately for the Formula car conditions. We analyze the strength of our system through FEA of our uprights, fixtures, tabs, and control arms.
Manufacture: Manufacture our control arms by utilizing jigs to weld. CNC’d our upright for the utmost precision.
Verify: Multiple track days will allow us to dial in on the perfect alignment for our vehicle at race conditions.
The Data Center for UCI’s electric racecar team. The telemetry team is primarily responsible for the design and implementation of the data collection system. Through this, we hope to provide information about the car’s mechanical and electric systems for our team's engineers for diagnostics and debugging.
Wireless Transmission System
The current system involves using radio frequencies to transmit data we receive from sensors mounted on the car. This will allow for a long range of transmission and minimal interference from other wireless devices (i.e. cellphones, laptops, etc.).
Data Collection Application
A desktop application to display data about the status of the car’s systems. The application can read data real-time or from files generated by the application.
Future plans include adding support for mobile devices and adding individual pages for different mechanical/electrical systems on the car.
We do more than just collecting data! We completed a cone detection system that uses Machine Learning to detect cones on the track.
Future Potential Projects include:
Real-time transmission of video from a camera mounted on the car
Implementation of an HTTPS Server to handle multiple application users connections
Driving simulation using our car specifications to train drivers while the car is being built
