The automotive and motorsport industries have long been driven by the relentless pursuit of performance, efficiency and innovation and as these sectors evolve, so do the tools and technologies that support them.
Among these, Driver-in-the-Loop (DIL) simulation stands out as a transformative force, offering unprecedented opportunities for development, testing and optimisation. From motorsport through to broader automotive OEM applications, the integration of advanced simulation tools is undoubtedly accelerating progress and redefining the boundaries of what’s possible.
At the heart of all effective simulation is the interaction between humans and technology. High-fidelity simulators provide drivers with realistic feedback that closely matches what they would experience in the real world – an approach that’s vital for optimising performance and gaining that all-important competitive edge.
The ability to simulate multiple racing cars and series underscores the versatility of modern simulators. By allowing extensive and varied test programs to be conducted in a controlled environment, teams can make quick setup changes, explore various chassis configurations, and understand track conditions without the expense and time constraints of on-track testing. This not only strengthens the collaboration between drivers and engineers but also enhances the overall development process.
Only recently, topflight motorsport teams Penske Autosport and Honda Racing Corporation USA (HRC) announced their respective investments in DIL simulation – with HRC upgrading its simulator in time for this year’s Indianapolis 500.
Capable of replicating the current Dallara-Honda Indy car, Acura ARX-06 hybrid GTP machine and a variety of Honda and Acura concept racing vehicles, Ben Schmitt, head of the Vehicle Performance Group at HRC US explains in the firm’s official press release: “The new simulator is superior in every way to our original DIL simulator. The vehicle physics models have continued to evolve from the original simulator, including the tyre models, and our data acquisition capabilities are exponentially higher than previously. The new motion platform, cockpit and vision systems create a vehicle dynamics experience for the drivers that is our closest recreation yet of real-world conditions.”
Realism is also key for those competing in the FIA ABB Formula E Championship – providing a data-rich environment where drivers can learn track layouts, optimise energy management strategies, and experiment with different race scenarios.
When it comes to gaining a competitive edge – on and off the track – engineers and drivers are looking for tools they can trust, and DIL offers the ability to replay and analyse multiple scenarios repeatedly, via a truly immersive experience that mirrors real-world conditions. However, engineers also need the capability to connect with a vehicle’s onboard powertrain ECUs via Hardware-in-the-Loop (HIL) and Software-in-the-Loop (SIL) systems – integration which facilitates the validation of critical components such as torque maps and electro-mechanical driver controls, ensuring that both the hardware and software are finely tuned before hitting the track.
One of the standout features of contemporary simulation environments is their ability to integrate with other advanced tools such as engineering-grade visual simulation environments – crucial for teams that need to adapt quickly to changing conditions. For example, there’s no need to wait for a real rainstorm because weather variations can be conjured up with the touch of a button; multiple tyres can be driven in rapid succession; a virtual racetrack can even be set up to loop one particularly critical track segment continuously.
While motorsport often leads in adopting cutting-edge technologies, the benefits of simulation extend well beyond the circuit. Automotive manufacturers are increasingly leveraging simulation to enhance vehicle development processes, reduce costs, shorten development cycles and reduce the environmental impacts inherent in the traditional build-and-test approach.
As the automotive and motorsport industries continue to evolve, the role of simulation will only become more critical thanks to its ability to provide a controlled, repeatable, and data-rich testing environment that is flexible as well as sustainable.
Whether it’s mastering the intricacies of a demanding street circuit or refining the dynamics of a new road car, simulation offers unparalleled opportunities to innovate and excel. As we look to the future, the seamless integration of these tools will undoubtedly expedite progress and set new standards for excellence in both motorsport and automotive development.
