Data logging systems have been in motorsport for more than 25 years. In the early days, the systems merely recorded lap times, but teams soon realized that recording data for later analysis was an invaluable tool. Not only could the analyzed data be used to improve the car’s performance, it could also help to improve driver performance.
As with all motorsport components, the competitive nature of the sport has lead to rapid development of the available systems. Engineers can now view ‘real time’ data as the car travels around a track, and drivers can examine theoretical fast laps to see where they can go faster and/or reduce their lap times. Also, it is possible to measure tire temperatures and pressures in 'real time' adding greatly to driver safety.
All data logging systems consist of the following base components:
For the average race car, the following sensors will be used:
