Last week a student-led team from the Massachusetts Institute of Technology participated in the annual international Formula SAE Electric car competition in Lincoln, Nebraska. Kx was one of their sponsors and provided Kx technology for race car sensor analytics.

The Formula SAE electric car international competition is run by SAE (formerly the Society of Automotive Engineers) to test engineering students’ ability to design and develop a small prototype Formula One-style car. The competition takes place over a few days, and includes autocross racing, with each team driving their own car. The cars are scored based on a number of criteria and tests including a design event; a cost and manufacturing analysis event, an acceleration event, a skidpad event, an autocross event; a fuel economy event, an endurance event and a presentation event.

The 33 members of the MIT Motorsports team competed against 26 clubs from top universities from around the US, Canada, South Korea and Brazil. MIT has had a motorsports team for over a decade, and the team this year achieved the best results yet.

During the race, measurements from both an IMU and GPS sensor suite provided accurate location and acceleration data. Other sensor data collected information about power draw, lateral acceleration, brake temperature, brake pressure, axis accelerometer, wheel speed and air temperature. The team used kdb+ for tracking and analyzing the streaming data coming from all of the on-board sensors recording each value in real time and visualizing the performance using Kx Dashboards. Their goals for 2018 included making accurate lap time predictions and doing virtual tuning, allowing them to get the exact stiffness, weight and desired power requirements for optimal performance.

After a day of racing on the circuit in Lincoln, the MIT team learned that their performance qualifications were excellent. They got pole position in acceleration and autocross (making them the fastest EV in the competition), and jumped to second place in skidpad. The outstanding team effort, together with the technologies in place to test performance, including kdb+ and Kx for Dashboards, allowed their car to cross the finish line two minutes ahead of the rest of the teams. Overall, they placed fourth due to a technical question that was decided against the team, but most importantly, MIT left Lincoln with the car to beat!



Kx Insights: Machine learning and the value of historical data

Data is being generated at a faster rate now than ever before. IDC has predicted that in 2025, there will be 163 zettabytes of data generated each year—a massive increase from the 16.1 zettabytes created in 2016. These high rates of data generation are partially an outcome of the multitude of sensors found on Internet of Things (IoT) devices, the majority of which are capable of recording data many times per second. IHS estimates that the number of IoT devices in use will increase from 15.4 billion devices in 2015 to 75.4 billion in 2025, indicating that these immense rates of data generation will continue to grow even higher in the years to come.

Sensors Working Overtime

Kx recently became an official team supplier to Aston Martin Red Bull Racing who is using Kx technology to handle mission-critical aerodynamic data. Below is an article published by Aston Martin Red Bull Racing on 11 January 2018 which explains the importance of this aero data, and working with Kx technology, for improving car performance for the F1 Team. It outlines how Kx’s in-memory, time series database software, capable of handling millions of events and measurements every second, provides a platform for analysing data on the RB14 and its successors.
