Driving the F1 simulator which gives teams “the best way to cheat”

Up to three people can sit in the Cruden Hexatech racing simulator

Up to three people can sit in the Cruden Hexatech racing simulator

F1 drivers will get their first runs in their new cars at Valencia in two weeks’ time. Actually, that’s a lie – they started driving them months ago.

The increased use of simulators in F1 means that while the FIA puts ever greater restrictions on testing mileage, teams are relying more heavily on virtual testing to develop their cars – and their drivers too.

Last week I sampled one of the simulators used by F1 teams to find out how they do it.

Once the 2010 F1 season gets started at Bahrain on March 14th the teams won’t be able to test their cars at a circuit until the championship is over eight months later.

Despite that the development race goes on – the cars will still have updated parts at more or less every Grand Prix. And the teams will already know more or less exactly how the new components will change their cars because they’ll have tested them in the simulator.

One simulator used by a number of current F1 teams – they wouldn’t tell me who or how many – is Cruden’s Hexatech IV which we featured on F1 Fanatic last month. I sampled the technology at the Autosport International show last week and had a chat to the company’s commercial director Frank Kalff.

More than testing

The first advantage simulators have over real-world testing is that the driver doesn’t have to be in there on his own. The latest version of the Hexatech has three seats, meaning he can bring a pair of engineers along with him. Kalff says:

Because the engineer is sitting there with the driver they can talk about what the car is doing in each different corner and how it can be made better.
Frank Kalff

The three-seat arrangement means the simulator can be used for more than just car development:

Teams use it for driver development as well – a driver can go into the simulator with a driver coach who can talk to him as he’s going around the circuit.

They use them for setting cars up for different tracks and working out race strategies.

And, of course, for simulating race distances. In fact we did a full 24-hour race once, with three drivers swapping turns. The only problem was every now and then we’d run out of memory and have to clear the buffers.
Frank Kalff

Car development presents one of the greatest challenges for simulation, however, as it needs to be able to emulate the car so accurately that changes to its set-up also have the correct effect:

The engineers have to ‘tune in’ the simulator so it models the car and any changes to it accurately. Once they’ve got a baseline where the car’s handling is realistic they then have to program in how it behaves when you change something on it.
Frank Kalff

As we talk a show-goer is strapped into the simulator, which is pushing and pulling him in every direction. It looks bit over-the-top, though – as if the simulator is exaggerating the effect going around a corner would have on a driver. Kalff explains why:

The system can be configured in a range of different ways. Racing drivers are very sensitive to car behavior, and if we set the simulator up to be as realistic as possible the average person wouldn’t feel an awful lot of movement.

At the moment we have this unit configured more for entertainment – the movements are a bit more exaggerated.
Frank Kalff

Behind the wheel

I get to experience that for myself first-hand when it’s my turn to sample the Hexatech. An assistant wearing a Cruden T-shirt bearing the slogan “The best way to cheat” directs me up the half-dozen steps towards the cockpit.

This model is fitted with an ordinary set of pedals mounted fairly low – in an F1 car they would be much higher. The steering wheel, however, feels very realistic, requiring a lot of force turn-to-turn. I move the seat into position and do up the full racing harness.

It’s running Cruden’s bespoke software which today features the easy-to-learn Elkhart Lake track (which would be my first choice of venue for an American Grand Prix) with Ferrari F430s. As the lights go out I stamp on the throttle and lurch backwards – as the simulator mimics the effect of heavy acceleration.

The first corner at Elkhart is a right-hander so I get on the brakes roughly where the computer cars do and yank the steering wheel. Now I’m being tilted and pressed into the side of the seat, and beginning to wonder if I should have done up the belts more tightly than I did.

But it’s remarkable how quickly you absorb the sensations of being pummelled from side to side and use the feedback to modify your driving. Mash the throttle too eagerly in a corner and the back end wriggles realistically.

The motion effect does fell a bit over-the-top and I’m keen to try the ‘full realism’ mode. Unfortunately there’s a queue forming behind me.

Six degrees

The Hexatech commands a price tag of ?é?ú120,000. That’s a lot of money if you’re just buying one to play “Forza Motorsport 3″ but small beer to an F1 team.

It uses six pistons to move the driver in every direction in a configuration called a Stewart platform. The technology was developed early in the 20th century for tyre testing, and simulators for other industries such as aviation have used the same principle for many years.

It allows the driver to experience six degrees of freedom – the full range of movements an object can move in.

Simulation will probably never replace real-life testing entirely. But it offers teams new ways of testing their cars as well as developing their drivers and honing their race strategy. As the technology improves future simulators will be able to perform even more of a team’s testing workload.

For me, the only thing it failed to simulate accurately was my name. ‘Kieth’? E before I next time, chaps.

  1. The title (esp. the cheating part) annoys me. :P

    Isn’t the testing ban there to cut costs? As such, simulators (and GP2 tests, etc) aren’t cheating. Not even against the spirit of the rules.

  2. it does look like something from the iron man movie but i would so love to have that in my living room. ÂŁ120000 you say. i better start saving!!

    That looks amazing!

    Keith do you know if the simulation software it runs is supplied with the hardware, or if the teams create their own simulation software bespoke?

      Cruden make their own software, but it’s all PC-based so you could run most stuff on it.

        While that’s technically true, it practically isn’t – the cuing and motion control has to be set up for a given simulator, and you need to get data output from the games themselves.

        My company (Force Dynamics) has unintentionally created a kinda-sorta defacto standard for driving sim motion output – it might even still be in RACER, which Cruden use; I haven’t checked. But Cruden’s software would have to be set up to use it. It’s nontrivial.

  4. Totally agree with you about Road America being a great track, I attended my first motorsport event there last year at the American Le Mans Series race and it was great, however, it seems doubtful that they could get the track up to the standard that modern F1 tracks require…there aren’t even any buildings in the paddock area except for the food stands! xD

    • there aren’t even any buildings in the paddock area except for the food stands

      K, let’s see…track-check…racecars-check…food stand-check……….alright, works for me ! :)

      What more do we need? :)

    If I win the lottery your all invited to my house to sample it.

    Could you load up wipEout on the thing?

    If the teams start develope it at the exteme I wonder if test ban is really a decreasing cost rule…
    Anyway it looks great. It should have been a funny experience, Keith.

    Could you play mario kart in there?

    damn i want one of those real bad :]

    If I hit the lotto, race party at my house!

    Does rather make Wii Formula 1 2009 look rather pathetic, although to be honest that isn’t hard :-D

  11. There is a cheaper way to feel this power :]

    I put some info with link to James Allen post about simulators maybe this help http://ow.ly/XsaV

    BTW I’m a big fan of your blog, so many archives,, thx

    If the actual component doesn’t meet up with the simulated expectation, then its game over.

  13. If their intention is to use that (amazingly cool) thing to train rookies, instead of sitting them BEHIND the driver, they should interlink (does this word exist?) two such toys with each other so the second unit gets all the movement from the first one, which would be the one actually driven. That would put the apprentice right in the position of the driver.

  14. “It’s running Cruden’s bespoke software”
    So what is the physics base? NKPro or Rfactor pro?
    Not the motion software…?????

    I am very envious right now.
