ARUS Racing: Success on the Track

Blog EuroCircuits x ARUS

Overview of the 2023/2024 season

After a year, the season 2023/2024 has reached its end, and we wouldn’ t have been able to meet our goals without the help of EuroCircuits. During the year, we built the first driverless car of the team, allowing us to participate in the different driverless events of Formula Student. Along with that, we managed to finish the manufacturing of our car much earlier, which made us have a more reliable single-seater in the events we attended:

• Formula Student Spain: Our first stop took place in Barcelona, Spain, where we passed our first DV-scruti. We completed the first driverless event of our team’s history: the acceleration, obtaining a P2. We also obtained a P2 in the Cost and Manufacturing event, and attended the Business Plan Presentation finals.
  
• Formula Student Germany: after that, we headed to Hockenheimring, where we also were able to pass all the scrutineerings and compete in the different events, such as the acceleration and the autocross.
  
• Formula Student Alpe Adria: our last event took place in Bugatti-Rimac’s test track. There, we finished our season by successfully completing most events in the electric category.
  

During the year, we’ve also designed the electronic architecture and the PCBs that we will include in our 2025 car, and, thanks to EuroCircuits, we’ve been able to prototype some of them already.

EuroCircuits Partnership

EuroCircuits has helped us build our cars by sponsoring us with high-quality boards during the years. This season, we’ve ordered several PBCs from them, which allowed us to finish our car months earlier and have a reliable electronic system.

Some of the systems that are controlled by these boards are our self-designed BMS (Battery Management System), our TSAL (Tractive System Active Light), our BSPD (Brake System Plausability Device) or the AS (Autonomous System).

Data-Acquisition PCB

We designed this PCB in order to have a reliable way of both reading the data from the different sensors that are included in our car and storing the values in an SD card, so that we are able to analyze the data afterwards.

Some of the sensors it reads are wheel speed sensors and linear extensometers for the suspension and the steering wheel. This PCB sends the data via CAN-BUS for our telemetrý system and stores the data in an SD card.

Tractive System Active Light

In order to comply with the rules, our car has to show a green light when there is not high-voltage outside of the battery, and a red blinking light when there is high voltage in the inverter or the motor. This PCB contains the different LEDs and circuitry needed to show this light in a very bright way, as it needs to be visible under bright sunlight.

We want to thank EuroCircuits for providing us with high-quality boards and helping us make a high performance and reliable EV!
