Accelerator/brake pedal position sensors: Race Studio 2 Analysis screenshots |

In the graphs below it is possible to understand how the accelerator/brake pedal position sensors provide useful information: |

The graph shows the brake position (red line) and the accelerator position (black line). Green line represents GPS speed.
In this graph it is evident that the driver correctly releases the accelerator when brakes, but the mistake is also evident when
he goes on braking even when he accelerates again. In the spot you can see that – for a while – both pedals are 100% down.
This behaviour generates understeering, as that the rear internal wheel does not lift and both wheels remain stuck to the floor.
This kind of analysis is possible just using both brake and accelerator pedal position sensors.

This graph shows a correct driving technique as when braking the driver correctly releases simultaneously the accelerator, and vice versa. |

Red lines show max. throttle opening (accelerator 100% down), blue lines show the reverse situation: throttle closed, accelerator in high position.
Shaded lines from red to blue show acceleration/braking phases.
In graph 1 track segments run with accelerator in high position are significantly longer than in graph 2: which means a less aggressive driving technique.
