Driving and Motion as Defined via Veh Performance and HOS
Discussion:
This is how it is currently handled for Vehicle Performance and Driver Information:
- A vehicle is deemed to be driving after it has been at rest and vehicle has moved a 1/2 mile.
- A vehicle is deemed not driving if either the vehicle is not moving (i.e. speed is 0) for over 5 minutes, or the engine is turned off (RPM is 0) for a period of 4 seconds.
This is how it is currently handled for HOS:
- A vehicle is deemed to be driving after it has been at rest and vehicle has moved the distance specified as 'Minimum Drive Distance' in the Web Portal (defaults to 1/10th mile).
- A vehicle is deemed not driving if the vehicle is not moving (i.e. speed is 0) for over 5 minutes.
How Motion is handled for BOTH:
A vehicle is considered to be in motion when speed is above minimum speed threshold.
If the speed data is received from the trucks SAE J1708 or J1939 bus then this threshold is 2 MPH and if using GPS, it is 7 MPH.
Above definition referenced on End of Day Rollup#VehicleMotionVehicleMotion as of 12/12/2016.
