<h1>5.1 What is a Car Setup</h1>
|
|
|
|
<h3>Introduction</h3>
|
|
<p>
|
|
Racing cars have a lot of parameters one can change. For example you can change
|
|
the angle of attack of the spoilers, the gears in the gearbox, the stiffness of the
|
|
springs and many more. A car setup is simply a set of such parameters. Our task is
|
|
to find an optimal car setup for a given goal. This is a very hard problem, because
|
|
the parameters are not independent. In fact it's almost impossible to find the
|
|
optimal setup. Why that? You can imagine all possible setups as n dimensional function
|
|
(with n the number of parameters) which computes the lap time. We want to find the
|
|
minimal lap time, so we have to minimize this function. Because this function has
|
|
(at least!) around 10 dimensions it's almost impossible to find the global minimum. What you can
|
|
get is a local minimum, which can be much worse than the optimal (global) one.
|
|
</p>
|
|
|
|
<h3>Qualifying Setup</h3>
|
|
<p>
|
|
In the qualifying the goal is to get the minimal lap time. Because there are no other
|
|
opponents on the track we can drive at the limit. We also just need fuel for a few laps.
|
|
The top speed on straights doesn't matter as long we reach the minimal lap time.
|
|
</p>
|
|
|
|
<h3>Racing Setup</h3>
|
|
<p>
|
|
The racing setup is a bit different. Of course you still would like to minimize the lap
|
|
time, but other things become also important. For example it is much easier to overtake
|
|
on a straight than in a turn, so you want to optimize the setup also for top speed on
|
|
a straight,
|
|
altough it probably will increase the lap time. The car needs also to be more stable,
|
|
so that it doesn't spin of the track when it tries to overtake or to avoid a collision.
|
|
Keep in mind if you want to win a race you have to reach at least the finish line...
|
|
</p>
|
|
|
|
<h3>Skill Level</h3>
|
|
<p>
|
|
There are four skill levels available, namely rookie, amateur, semi-pro, and pro.
|
|
On rookie you have a lot of adherence and no damages, with pro you get a lot of
|
|
damage and less adherence. I mention that here, because this affects the setups. The
|
|
default skill level is semi-pro. You can configure it for every car individually
|
|
in the <span style="color:red;">bt</span>.xml file. Add the skill level line in the
|
|
section of the car you want to configure, e. g. for the car with index 0:
