From Wiki Knowledge Base | Teltonika GPS

Description

Overall purpose of FMS ECO Driving is to monitor drivers behavior by reading FMS CAN data from the truck and sending a report to the server which allows the fleet manager to see the driving style of specific drivers - good driving styles can be rewarded, and bad driving styles can be corrected. Good driving style means that the driver is using the whole spectrum of trucks capability - engine breaking (retarder), coasting, cruise control etc. and is predicting the road/traffic conditions ahead - using the momentum of the truck when needed, not overusing the brakes etc.

The main benefit for the client is that FMS ECO Driving report allows them to make and monitor driver behavior changes to save fuel costs and maintenance cost of the truck - saving more revenue and making the company more environmentally friendly.

Additionally, clients can also reduce the data traffic of the device and save data cost as well - instead of monitoring live FMS data from the trucks - new functionality accumulates the data inside the device and sends a report by specified triggers/period.

Notion List

Cruise control - selectable option in the truck - by using cruise control the truck can use optimal fuel consumption to maintain the speed window selected by the driver.

ECO Roll - option that if enabled in truck uses neutral gear to roll using truck momentum on slopes

Coasting - similar to ECO Roll, however the Cruise Control is not active and gear is not neutral - simply letting off the accelerator pedal.

Power take-off (PTO) - is a device that transfers an engine's mechanical power to another piece of equipment.

Retarder – A hydraulic accessory that is connected to a gearbox which slows down the truck by slowing down the gearbox. It is operated by levr in the truck.

FMS eco driving functionality working

Units

Driver behaviour can be monitored via various accumulators - Distance travelled in specific state and/or Fuel used in specific state and/or Time spent in specific state. Additionally count accumulator is also available for specific elements.

Client can select what accumulator is required to him by enabling it in configurator. For example, Braking Accumulator:

Braking AccumulatorsPVZ.png

In report you can get:

  • distance travelled while brake pedal was depressed
  • fuel used while brake pedal was depressed
  • time in seconds of how long the brake pedal was depressed during the trip
  • count - number of times the brake pedal was depressed

Example: report states that Braking accumulator count is 10 while distance travelled while brake pedal was depressed is 2 km - the driver is feathering the brake to slow down the truck instead of using engine braking.

Important: IO elements appear in record if the trigger that generated the event is enabled for the element - for example report is generated by trip end - periodical accumulators will not be included in the record and vice versa. However - more than one trigger can be selected.

Triggers and others

As mentioned, - FMS ECO driving is a report-based functionality - purpose is to get a report on drivers' behaviour after each trip he takes and not to monitor the data while the trip is happening, however a possibility for that also exists. Some Triggers are hardcoded, for example:

  • Startup – Permanent trigger. Generated on device start-up. Indicates that accumulation has begun.
  • Powerdown – Permanent trigger. Generated on device reset command. Intended for saving current accumulators to Flash on software reset.
  • DriverID – Permanent trigger. Generated on active driver ID change detection. Changing driver ID should always send current accumulators so that they would not be assigned to another driver. Two reports are sent on this trigger: one before accumulators are reset (to get a report for the previous driver) and one after (to get a reference starting point for a new driver).
  • EndOfDay – Permanent trigger. Generated every 24h near midnight. Event is triggered in time interval from 23:56 to 00:00. All accumulators are sent and cleared.


Clients can also select additional triggers for each element - Trip/Periodic:

  • Periodic – Configurable trigger. Only accumulators that have “Periodic” setting configured are sent and cleared. Generated after every periodic Tacho record generation (separate period configuration will be available in upcoming release).
  • Tachograph Record Settings in "Tachograph Data" Tab:

  • Trip Start – Configurable trigger. Only accumulators that have “Trip” setting configured are sent and cleared. Generated on trip start.
  • Trip End – Configurable trigger. Only accumulators that have “Trip” setting configured are sent and cleared. Generated on trip end.

FMS Eco Driving Report Structure

FMS report comes in separate record with specific AVL ID - 12000. The value of AVL ID specifies what trigger generated the report.

After each FMS ECO Driving report is generated - the accumulators are renewed - counting starts from zero.

The record structure description could be found HERE
