Toto Talks Portugal

Seeing Lewis cross the line in Germany and take his 91st victory was a very special moment. Valtteri’s race, however, could not have gone much worse, going from pole position to a DNF and a significant points loss for him in the Drivers’ Championship. It was undoubtedly a tough blow at this stage of the season. We have identified a failed electrical component in the Control Electronics as the cause of the problem and the evidence suggests that swift action in retiring the car prevented mechanical damage to his Power Unit.

A DNF is always tough for a driver, but one of Valtteri’s biggest strengths is his resilience and his ability to bounce back, so I’m sure he’ll be eager to hit the track in Portugal. Portimão is the second completely new circuit of the season, which adds some variability to the potential performance picture. We had an exciting race at Mugello, the first new venue this year, and since then we have focused on preparing in the best way possible for the other new circuits and maximising the rate of learning when we go to a new track – something that will be especially important during the two-day weekend in Imola next week.

The car’s performance was good in the last few events both in Qualifying and in the race and we hope that we can maintain the momentum.

Fast Facts: Portuguese Grand Prix

  • One of the most striking characteristics of Portimão is the elevation change, with the track rising and falling frequently – and on occasion, quite steeply - throughout the lap.
  • The undulations create some blind corner apexes and exits, which can make it tougher to learn the circuit and build up speed during those initial laps.
  • We’re expecting overtaking to be tricky in Portugal due to the flowing nature of the track and lack of heavy braking zones. The only DRS zone is on the main straight and the quick final corner will make it harder for cars to keep a tight gap. The zone itself is very long, so this should give drivers the chance to close up on their rivals.
  • The Turn 10/11 complex is anticipated to be the most challenging part of the circuit for the drivers, because it’s a double-right with a blind entry and a downhill drop on exit.
  • However, there’s also an unknown ahead of the #event as to whether Turn 10 should actually be classified as a corner – some maps of the track do so, therefore giving the track 15 corners, while others say it isn’t and state there are only 14.
  • On paper, the track layout itself should suit higher downforce levels but because of the long main straight, we’re likely to see teams trialling different wing settings in practice to decide where the compromise is – being faster in the corners or protecting yourself on the long straight.

Featured This Week: How Does #f1 Simulation Work?

F1 cars are the most sophisticated #automotive machines in the world – and yet, testing them on track or in the wind tunnel is extremely limited. There are only six days of pre-season testing and each race weekend comes with only four hours of practice. That’s why Formula One teams rely on gathering data in the virtual world more than ever before – and a big part of that work is simulation. This area has become even more crucial during the 2020 season, because of the many new tracks on the calendar.

What types of simulation do #f1 teams use?

There are a few areas of simulation that #f1 teams use to prepare for a Grand Prix weekend, but the two main ones are driver-in-loop and computer simulation. Driver-in-loop (DiL) is effectively our virtual test track, where our car and the tracks we race on are modelled in incredible detail, to enable us to develop the car, find the right set-up direction and help the drivers familiarise themselves with a track in a virtual environment. We use a bespoke simulator facility at the factory and the DiL is somewhat similar to a professional airplane simulator used for pilot training – with the obvious difference that our “cockpit” looks like an #f1 car, not a flight deck. In a typical DiL session, our race and simulator drivers can easily complete more than a full race distance. However, in that same space of time we can log thousands of computer simulations as computer simulated laps can be done 100% virtually. That means they can be sped up and run in parallel with other simulations to support both the vehicle dynamics and the strategy groups. The value of these different virtual tools is critical for an #f1 team, particularly when we’ve never raced at the track before.

How accurate is the Driver in Loop simulator?

The track models that we use are highly detailed. They are generated by lidar scanning, where laser imaging is used to create a 3D map of the entire circuit and all of its characteristics - from track surface to kerbs and even the environment around it. #f1 teams also work with gaming companies to make the track environment as realistic as possible, as visual cues are important for the drivers to determine braking points or the right moment to start turning the car. The market for these highly complex track models is fairly small, so multiple teams will often base their simulations on the same track data and information. The simulator itself is designed to be as realistic as possible with the same chassis, cockpit, steering wheel and pedals as the car itself, and drivers will often run in full race kit to really immerse themselves in the experience. A significant amount of time is spent correlating the virtual model of the car to the car in the real world, so that the car can handle in the simulator just like it does out on track. This allows us to run through set-up tweaks and changes to the car, as we would at the track, to see how it changes balance and performance.

Why is the Driver in Loop simulator so important and does our approach change for new tracks?

It’s an incredibly important part of our preparations and it’s especially vital when visiting a new track, where you have little to no historic data. While our approach remains the same, it does mean the team is more dependent on gathering information in the simulator and as a result new circuits require a more extensive programme. For a track that we’ve visited before, we’ll typically dedicate a two-day programme in the build-up to the #event, equating to around 450 laps and roughly eight race distances. The majority of the running is completed by our team of simulator drivers, but Lewis and Valtteri also use the facility. However, when it’s a new circuit, the amount of work is much higher, with two additional days in the run-up to the #event plus another day dedicated to the race drivers learning the track layout. The bulk of the work is completed in the build-up to the race weekend, but the work doesn’t stop when the team arrives trackside. The simulator department also run a Friday programme for each Grand Prix, supporting the drivers and engineers at the track to really maximise the learnings from the first day of action. And once the weekend is over, the sim is fired back up to conduct a post-event programme to further understand race performance and assess potential improvements. All of this crucial pre-event work is conducted to ensure the team arrives at the track with the car in a good enough place that the drivers can begin pushing hard from the very first laps.

How do teams use computer simulations to gather information?

Alongside the DiL programme is another virtual test track, but this time, it lives completely inside the computer itself. A #racing line file is generated from the DiL to create a single trajectory around the lap and this #racing line is used to complete hundreds of thousands of virtual laps ahead of each #event, producing a few terabytes of data. The engineers are able to speed up these computer simulations and run them in parallel with one another, with this much faster pace allowing a vast amount more information to be gathered in a much smaller amount of time. From the vehicle dynamics side of things, engineers are really focused on the details - both in getting information on very specific parts, but also seeing how the car reacts to very small set-up changes. A huge number of set-up possibilities are run through the simulations and the data output – often in the form of a graph – can be compared, not only from the other runs but also overlaid on top of the DiL or real car information. Our technical partners play a crucial role in our computer simulation capabilities, with HPE providing data centre infrastructure and hardware, Pure Storage bringing storage solutions and TIBCO giving us the mechanisms to visualise and report the findings from our simulations. Once the data has been analysed, the team then decide what direction to take with the car set-up for Friday’s practice sessions and this will be used as a base to start the development of the car out on track.

What other areas of the team use computer simulation?

Another critical area for simulation is strategy. The computing models used for these strategy simulations feature all drivers and teams, but also include assumptions for pit stop scenarios and the variables of the circuit, such as pit stop loss, tyre degradation and car competitiveness. These are bundled into the computer simulations with some realistic element of variability to account for a wide variety of situations, which run many different race and Qualifying session scenarios in order to work out the best strategic options – from which tyres to use, to what lap to pit and how to react to losing or gaining places at the start. Running this vast array of strategy simulations is also useful for working out the programme for Friday’s practice sessions, revealing what information will need to be gathered or what details the team is missing. Before we’ve even turned a wheel at the track, hundreds of thousands of strategy simulations will have taken place in order to put the strategy team in the best possible position heading into these live sessions.

What challenges have teams faced during this unusual season?

One of the most obvious challenges that teams have faced this season is the sheer volume of new circuits to prepare for. Typically, a new season will include one brand-new track. Simulation work for these unknown circuits start as soon as the calendar is confirmed, usually six to eight months in advance. However, this season the schedule has been ever-changing and races have only been confirmed two or three months ahead of their planned dates. And of course, from the 17 confirmed races, three layouts (Mugello, Portimão and the Bahrain Outer Circuit) have never been raced on by #f1 before and three others (Nürburgring, Imola and Turkey) haven’t been visited by #f1 for quite some time. So, it’s much harder to gather the same volume of information as usual due to the tighter timeframes.

Can these methods simulate everything?

We aim to gather the most accurate info we can from the DiL and computer simulations, in order to be in the best shape possible, come FP1. But of course, these simulations can never be 100% accurate and are only as good as the data that’s put into them. Because of this, simulations are never used to finalise decisions, but instead used to assist and influence the direction that the engineers go down. Once the path has been chosen, it is then down to the drivers to provide real-world feedback and for the engineers to take this information onto the next level. The full car model can never be perfectly accurate, and you also can’t model the grip of the tarmac and how the tyre responds to it. Some aspects of the car set-up, such as wing levels, are easier to gather information on through simulations while others, such as car balance or grip levels, are more difficult because they depend on more factors – some of which are outside your control, such as the weather. We can make assumptions for the simulations, but you’ll only really know how all of the elements interact together once the car is out on track for real. The important thing for the race engineering department is to understand how to interpret that simulation information and, given its limitations, how to combine it with the real-world data, bringing it together to make the right decisions.
