By default, Omnitracs defines hard braking as occurring when the vehicle is traveling at more than 20 MPH and its speed decreases by at least 9 MPH per second for three consecutive calculations, each made 0.2 seconds apart. Omnitracs also defines any activation of the ABS as a hard braking event.
To view events meeting different criteria, create a filter with your desired speed and deceleration settings. Company administrators can create filters on the Settings/Filters page.
Note: While the speed data may show occurrences of decelerations of 9 MPH per second, this may not necessarily indicate a hard braking event as determined by the above algorithm.
