How to read the data collected from the main telemetrics
TKART Staff
25 March 2017

In motorsport, apart from the engine, chassis, tyres and mechanical parts, electronics has now also become a decisive factor in determining a winning car. To begin with, in this article we provide an overview of the typical screens of the most important sensor channels that, when installed, help to understand how karts and drivers are behaving.

1.Where is the starting point for reading track data collected by the instruments?
A typical main screen is one that shows the channels useful to have, in a single glance, a general idea of lap performance (and perhaps, as in the screenshots at right, a first comparison between two drivers): speed, steering and throttle. The graphics can be displayed based distance or time.

2. Let’s go into detail in regard to the individual channels: speed?
The speed of a kart can be measured based on the GPS signal, or by installing a sensor that reads the speed of the rear axle, or one of or both of the front wheels.

In this case, the sensor actually measures an angular speed that must be converted into km/h, after calculating the rolling radius of the tyre in accordance with the following equation: V [km/h] = ω [rad /s] * R[m]

The two systems, GPS and sensors, can also be used together, since one does not absolutely exclude the other.

Let's say that, although both channels should theoretically provide the same value (since they both measure kart speed), it is normal to notice a difference in the two graphs.

This is due to ...(keep reading on "THE EXPERT ADVICE" TKART Magazine channel)

3. And what about the engine?

4. But what about the chassis data?

5. Finally, shall we talk about acceleration?
