To detect harsh or risky driving behavior, Mentor directly leverages readings from built in accelerometer in combination with derived acceleration values defined as rate of velocity change. Mentor’s “Harsh Acceleration” thresholds are based on industry best practice and eDriving’s own field testing. These are subject to change in light of experience, industry standards, and in-house research.
Mentor’s current “Harsh Acceleration” threshold is set at 0.41 g or 9 mph/s increase in speed.
