Self-Learning

Self-Learning systems, such as our Lite and Pro series, compare the rate of acceleration of the driveshaft to a calculated threshold value that is constantly updated based on the average of the previous measurements. This update occurs on every driveshaft revolution.

So, if the last 1/8 of a turn of the drive shaft is faster than the average of the last full revolution, then a slip is detected.

Through this very advanced Patented process, the system constantly accounts for track conditions, tire condition, etc. to constantly update the internal settings. These settings are updated as many as 800 times a second to keep the unit calibrated to exactly the right settings, regardless of changing conditions.

Basically, the systems learns the average rate of acceleration of the driveshaft, and if there is a sudden spike in RPM above that learned rate, then a correction is made.

With the Self-Learning feature, the user doesn’t have to try and figure out the DS RPM rate of change and set a “Threshold”, the system does it for you, every driveshaft revolution!

The user does have an adjustment referred to as “Mode” that sets the overall sensitivity of the system to make a correction based on the extent of the tire slippage. By adjusting the Mode, the user can tune the system to correct larger slips, while not reacting to smaller, harmless, slips.

The biggest difference in our systems is the Speed and the Self-Learning abilities. Other systems “brag” that their TC works 10 times a second—our older systems worked 20 times a second, and while it would help “save a run”, it just was not fast enough to help you go faster.

The new systems (since Jan 2009) work every 1/8th of a turn of the driveshaft. At 3000 RPM DS speed, a very critical area for tire slip, it measures the DS RPM 400 times a second, at 6000 DS RPM it measures 800 times a second!

The system then processes those measurements 50 times a second (typically), and as fast as 100 times a second, to calculate acceleration change (DS RPM Delta). (We can actually use up to 30 triggers, which would be 1500 times a second at 3000 DS RPM, and 3000 times a second at 6000 DS RPM !!)
