dSPACE is expanding its partnership with the international student competition Indy Autonomous Challenge (IAC): In addition to the AUTERA on-vehicle computer, high-fidelity simulation solutions will enable teams to test and validate their control software at an early stage. Simulation expert Dr. Hagen Haupt explains the details.
Hagen, dSPACE supports the IAC with software simulation packages. What exactly will they look like?
Yes, at dSPACE we are looking forward to supporting the teams at the IAC with software simulation packages that allow them to test their control software in a virtual environment. This method is called software-in-the-loop (SIL) simulation.
Specifically, we support them with SIMPHERA, the latest simulation and validation solution from dSPACE. SIMPHERA is a powerful framework that incorporates simulation models, test automation, test analysis, and a simulation platform to be used on desktop PCs and in the cloud. SIMPHERA can also integrate further components such as hardware-in-the-loop (HIL) simulators. Installed on a desktop PC SIMPHERA offers the teams full access to all components of the framework, so that they can configure these to meet their needs. For example, they can replace components of the open simulation models with their own models. Used in the cloud SIMPHERA provides maximum comfort in the simulation. All that is needed here is to upload the self-developed control software – AI Driver – to the cloud to immediately carry out the first driving dynamics tests.
And don’t worry – we offer all teams a comprehensive introductory training and are by their side to support them during their simulation projects.
What can the teams do with the software simulation package?
With this package, the teams can test important aspects which are relevant for the performance on the racetrack. Of particular interest is, of course, the AI Driver and how it reacts to its environment, e.g., the racetrack and other vehicles. The simulation and analysis of interference effects and sensor errors such as GPS shadowing are important here. Driving dynamics tests are also carried out to determine the vehicle's performance in advance. So statements such as “How fast can the vehicle take the curve?” can be answered quicker and more safely in the simulation than on the racetrack. Classic reliability topics are valuable: Does the motor actually turn when the corresponding signal is present? All knowledge gained through simulation helps to make the vehicles more reliable and more performant. The objective is to prepare the vehicle software as well as possible for the race. Everything that was already solved in the simulation no longer has to be forced in the hectic pace of the racetrack.
How are racetracks, tires, and other factors considered in the simulation?
We at dSPACE want to ensure that the teams have an environment that is as realistic as possible during the simulation. That's why we are planning a ready-to-use setup, which includes the track, the vehicle, and other relevant components. We want to ensure that the teams receive the best possible support and are able to design their simulations as realistically as possible. Furthermore, we will observe how the teams cope with that and which additional support is advisable.
Are virtual races against each other possible?
Individual simulations of each team are not the end of the story. With SIMPHERA, we will make it possible to execute virtual races in the cloud. Two teams can race against each other virtually and compare their performance in comparison with other teams. That is an exciting opportunity to measure the performance of the teams and to enrich the competition by this exciting component.
What is the situation with sensor simulation?
We have our eye on it, because it is particularly interesting for autonomous driving. At first, we are concentrating on vehicle dynamics to create a solid basis. In the future, we will also enable sensor simulation. In this manner, the virtual tests and races will become even more realistic. And for teams that already want to become more active in this field, we are making three packages of AURELION, our sensor simulation software, available.
How will the subject of simulation develop?
We know already: A simulation-based approach has become indispensable in the automotive industry. In the development processes, dSPACE supports with both SIL and HIL technology. It is precisely this approach, which is established in the industry, that we are making available to the IAC teams. The advantages are an early gain in knowledge and more efficient development. We are convinced that simulation is the key to innovation – including at the IAC. It will, however, be important that the sponsors of further vehicle components for the IAC race cars provide their models and measurement data, in order to facilitate realistic simulations.
What would you like to tell the teams?
The teams of the IAC are very competent and experienced. We are looking forward to a high-level exchange. dSPACE would like to provide a valuable, industry-tested solution to inspire their success. The only thing left for me to say is “Start Your Simulation!”.
Hagen, thank you for talking to us.
