A quick
explanation of the Data Display. The data is collected by an AIM
Evo4 unit. the data is then added to the video using RaceRenderer
3 software. Upper left is a track map drawn from GPS data. Next
to it is the 'GForce' sensor display. When the moving dot reaches
the edge of the first circle, I am under one 'G' load. In other
words, I am being pulled as hard sideways as gravity is pulling
me down. This data is from an internal accelerometer. The next display
is the speedometer. The speeds are calculated from the GPS. The
lap times and lap number are calculated by GPS and not from the
official transponder. The latest lap time holds for ten seconds
after the end of the lap to make it easy to read.
The
two vertical bar displays at the bottom of the screen display energy
(rather than power). The right display shows how much energy in
Watt hours is being pulled from the battery pack. The left display
shows the Watt hours that are being used to overcome motor inefficiencies,
rolling resistance, aero drag. This is calculated by taking the
previvious kinetic energy (calculated from speed and vehicle weight)
plus energy in from the battery and subtracting the kinetic energy
now (calculated from speed and vehicle weight). The difference is
the energy used up and not being added to the kinetic energy of
the vehicle.
Race
1. First six laps with data display.
Race
2. 31 laps before rear tire blows while leading. Abrasive track
surface and lots of rear wheel regenerative braking wore the tire
through after 132 laps. Look for a moment around lap ten when the
steering fails on the car directly in front of me.
