Use the the Driver Efficiency Report (Fuel & Energy > Driver Efficiency) to view essential information about driving styles that can affect the fuel consumption and wear and tear of vehicles in your fleet. When you coach drivers on driving style, you can help to reduce fuel costs and reduce your ecological footprint on the environment. For instance, if you identify high torque scores in the efficiency report, you can coach driving behavior to decrease aggressive acceleration instances and reduce fuel consumption over time.
The Driver Efficiency Report primarily supports fleets with heavy duty vehicles and larger commercial vans. For light duty and passenger vehicles, Samsara supports only Over Speed and Idling metrics.
To tailor the report settings to your fleet and drivers, you can weight the driver efficiency parameters (see Driver Fuel Efficiency Scores). For example, if vehicles in your fleet spend a lot of time driving on highways, you can assign more weight to the Cruise Control parameter. Conversely, if your vehicles operate with a lot of stops, you can assign more weight to the Anticipation parameter.
To drill down into efficiency scores you can view the following reports:
For each report, you can set the scope in the side bar on the left. The scope can be either Drivers or Vehicles. You can also adjust the scope to display drivers or vehicles associated with specific tags.
 |
Within the Summary view, you can view the overall Efficiency Score of your fleet for the selected time period as compared to the previous time period.
The Summary also displays a trend line graph for all selected driver behaviors for the entire fleet or by tag. You can modify these trend lines by:
-
Comparing certain tags for individual behaviors
-
Changing the score type from grade from a numeric value to a percentage
Below the Summary, you can also see a leaderboard that highlights the top and bottom five tags or drivers depending on your selection.
The tag leaderboard displays the number of drivers and the combined score for the drivers in each tag group.
The driver leaderboard displays the score for each driver.
 |
You can view efficiency scores either by vehicle or by driver depending on your selection in the side bar. If your fleet does not use driver assignments, you will see Unassigned as the only driver in the Drivers tab. All eligible vehicles are included in the Vehicles tab.
By default, the report is sorted chronologically. To narrow the focus of your results, use the date selection to change the time period, Search to search for individual drivers or vehicles. To manipulate the report, you can also change the sort order by overall scores or individual metrics, and change the score type.
The report displays the following information for each driver or vehicle:
|
Field |
Description |
|---|---|
|
Driver or Vehicle |
Name of the driver or vehicle. |
|
Overall |
Overall score across all parameters. The default score varies according to region (in Europe the default is A-G and in North America the default is 0-100). Based on the controls above the table, the score is shown as one of the following:
|
|
Cruise Control |
Time a driver uses cruise control in proportion to driving time. |
|
Coasting (Any Gear) |
Time spent without engaging the accelerator or brake in proportion to driving time. |
|
High Torque |
Time the vehicle engine torque is greater than 90% in proportion to driving time. |
|
Idling |
Time when the vehicle's engine is idle and PTO is not engaged in proportion to the engine on time (driving time plus idle time). |
|
Anticipation |
Quick breaking events (less than one second after accelerating) in proportion to total braking events. |
|
Green Band |
Time in efficient RPM (800 to 17000) in proportion to driving time. |
|
Over Speed |
Driving time spent over the Efficient Speed threshold. This threshold is not the same as the speed limit, but rather the maximum speed you would like drivers in your fleet to travel for efficiency reasons. As a best practice, you can adjust the value to reflect a target maximum for your drivers that are specific to the vehicles they drive. The default threshold varies depending on region (80 kmh or 50 mph). |
|
Driving Time |
Total time the vehicle has been on and moving (excludes idle time). |
|
Engine On Time |
Time a driver spends with the engine on. Driving time plus idle time. |
