The Formula Student competition is a proving ground for the brightest engineering students from around the globe. Each year, the racing team from Esslingen University participates, striving to showcase their cutting-edge innovations in motorsport. For this season, the team implemented the OMS7 optical sensor system from Sensoric Solutions—and the results have been impressive.
The Need for Real-Time Precision
The team at Esslingen has developed an all-electric vehicle with all-wheel drive, specially tailored to the Formula Student competition. To achieve peak performance, the students devised a sophisticated state estimation system to ensure optimal torque distribution to all four wheels. However, they faced limitations: speed measurement errors of up to 12 mph (20 km/h) had previously hindered traction control and overall vehicle handling. With Sensoric Solutions’ support, the team tackled these challenges head-on.
Installation and Integration of the OMS 7
The OMS 7 sensor was mounted directly on the vehicle’s rear axle, allowing for precise measurements of longitudinal and lateral speeds. Despite the space constraints in a single-seater, the data processing unit was seamlessly integrated and protected from vibrations. Now, with high-frequency sampling at 1000 Hz, the OMS 7 delivers accurate, real-time data that the team uses for vehicle control.
Data That Makes a Difference
With the OMS 7, Esslingen University’s racing team can now reliably measure speed and determine the vehicle’s slip angle. This information is crucial for maximizing traction in curves and optimizing tire wear. The result: reduced speed discrepancies between wheels, improved slip control, and significantly enhanced vehicle stability.
During the Formula Student events in the Netherlands and Hungary, the benefits of the OMS 7 were clear. The sensor allowed for precise measurement of tire camber angles, providing the team with valuable insights into their car’s handling characteristics. They were able to make real-time setup adjustments based on these data points, ensuring the vehicle was perfectly tuned for demanding tracks.
Conclusion: A Milestone for the Team
Sensoric Solutions’ OMS 7 has enabled Esslingen University’s racing team to elevate their vehicle dynamics to a new level. The precise measurement of acceleration data allowed for improved traction control and significant stability gains. In dynamic events, the team could push even closer to the limits, shaving valuable seconds off lap times—a true competitive advantage.
Sensoric Solutions is proud to provide innovative technologies that help racing teams achieve their goals. The OMS 7 has proven it’s more than just a speed sensor—it’s a tool that makes the difference between average and outstanding performance.
