This season’s Formula E rules feature several new twists: The pit stop has been abolished. The race distance is now measured by time rather than in laps. And the new ‘attack mode’ gives drivers a brief-but-powerful burst of power to overtake or keep rivals at bay. “This has a major impact on the power strategy for our drivers Daniel Abt and Lucas di Grassi and on the software development for their Audi e-tron FE05. New systems such as a stronger battery and the active braking system have to be integrated into the software for peak performance,” says Sven Wergandt, Motorsport Program Manager at ITK Engineering.
Newly developed algorithms serve to store the strategies and the power distribution mapping calculated before a race on the vehicle’s control unit. Then they have to adapt to the given road conditions in real time. “There is no telemetry from the car to the pit in Formula E. That’s why software has to work as autonomously as possible. The driver and vehicle are on their own, particularly when it comes to power distribution,” says Wergandt by way of explanation.
From the race track to the assembly line
Virtualization and simulation tools help adapt to changing requirements on the fly even without empirical data from the race track, and meet the loftiest standards for quality, traceability, test coverage, and documentation. “Formula E is an R&D development lab where major manufacturers and technology companies such as ITK Engineering can make strides towards eco-friendliness, efficiency, economy and sustainability, and carry these advances over to production vehicles. As software developers, we take a keen interest in Formula E because it lets us put all our know-how to work,” notes Wergandt.
Dieter Gass, head of Audi Motorsport, ads: "To be successful in Formula E, many details and far more than just the fastest car in the field matter. Efficiency, recuperation, strategy and battery management – powertrain and software have to smoothly interact so that our drivers are able to rely on their Audi e-tron FE05 one hundred percent. That’s the key to success in this racing series. In ITK Engineering, we’ve been enjoying the support of an experienced partner for many years – not only in terms of creating the software but also with regard to its permanent tuning and further development.”
