Centralizing ECU data into a SQL Server relational database makes it easier for racing teams to find the specific data sets they need during the process of preparing for a race. “Preparing the car for a race begins long before going to the track, with the team performing simulations and testing,” says van Manen. “Once at the track more data is generated with each test run, and from this pool of information the teams try to determine the ideal calibrations for the car.”
With all of its data stored in a centralized relational database a team will be able to immediately access relevant data from historic captures. For example, a trackside team preparing suspension calibrations for a specific track could simply enter the name of the track to access all data streams that have been collected from previous visits—including variations in track and ambient temperatures.
“A Formula One race car is incredibly complex and can be minutely calibrated to meet the needs of a specific track, the weather, and a list of other variables,” says van Manen. “The tires are what translate power to the ground, and factors like tire choice and pressure influence traction, braking, and cornering. Dampers [shock absorbers] and other parts of the suspension are calibrated as are the gearbox, motor, and wings that create downward pressure to keep the car on the track. Storing ECU data in SQL Server gives teams the visibility they need into a world of high-value data that would otherwise be difficult to make use of.”
Giving race teams the ability to search their own database for relevant performance information will help them in their constant quest to balance two opposing racing factors that can otherwise be in opposition: The driver’s need for dependability and predictability in the car, while pushing the limits of performance.
“A driver might roll into the pits and report that the car isn’t coming out of the corners as well as it should be,” van Manen says. “The trackside crew needs all of the relevant data points they can find to determine if they should be changing a suspension setting, using a different type of tire, or changing the gearbox.”
Ready access to vast data helps teams respond to the unexpected developments that come with racing. Van Manen notes, “There is a lot of science involved in preparing the car, but there is also a lot of art to racing, which means teams need the ability to rapidly respond to the unexpected.”
