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 Braking” 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 Braking” threshold is set at 0.41 g, or 9 mph/s decrease in speed.
