10.11.2. Traction control hi nts
 If problems with the TC occur, first try to get rid of them by
altering the target slip. The target slip is dependant on the race
track.
 Under normal conditions, the controller does not need to be
recalibrated. I
 Do one step after another, one variable at a time!
 Beware of doing huge steps in calibration. A D-component
mu
ltiplied by two will lead to instability of the controller and
strong oscillations in the drivetrain. Calibration of a PID-controller
needs a lot expertise in control engineering!
 If you are not sure about your calibration, go back to the neutral
values.
 Watch the recorded data
solutions to your problem!
If the TC doesn't work fine, first check the incoming signals:

accx, accz, accy correct?
yaw and steer sensor correct?
vrad_fl, vrad_fr, vrad_rl, vrad_rr on the same level on the
straight?
t is suited to the car prior to the racetrack.
