Eco/Green Driving

FMB0YX Green Eco Driving feature.png

When vehicle parameters exceed the values of Max Acceleration, Max Braking or Max Cornering parameters, the scenario is activated: a record is generated and digital output status is changed to 1 when configured. You can configure all three parameters in m/s2 units. Scenario is activated until current Acceleration, Braking or Cornering value decreases below the set parameter value.
Parameters used with Eco/Green Driving functionality are given in a table below.

Parameter name Description
Scenario Settings Enable/Disable Green driving functionality
Max Acceleration Value which can be reached while accelerating without triggering harsh acceleration event.
Max Braking Acceleration Value which can be reached while braking without triggering harsh braking event.
Max Cornering Acceleration Value which can be reached while cornering without triggering harsh cornering event.
Source Which source (GPS or accelerometer) data will be collected from.
Eco/Green Driving Duration If enabled, additional record with Eco/Green Driving event duration (ms) will be saved and send to server. When GPS is selected as the data source duration accuracy will be in seconds.







Data output


Data from accelerometer/GPS are continuously monitored and processed and are used to decide whether a harsh event has occurred. If either of three cases is satisfied, an event is generated and a record is saved and sent to the server (FMM001 must be properly configured in order to send the record). Event value is multiplied by 100 before sending/saving record to get more precision when displaying data.

Auto calibration


The auto-calibration process is following:

  1. The vehicle is stopped.
  2. There is a straight road ahead.
  3. Send SMS "auto_calibrate:set" to the FMM device.
  4. Accelerate to >30 km/h for 5 sec.
  5. FMM will send a response when calibration is completed successfully.

Calibration is saved to internal flash memory, which means it will stay after a reset. To check auto-calibration status send a following short text message to the FMM device: "auto_calibrate:get".

Over Speeding

size

When vehicle speed exceeds configured maximum speed value the scenario is activated, an event record is generated and digital output status is changed to 1 when configured.
Scenario is active until detected speed decreases below the set parameter value.



















GNSS Fuel Counter

size
  1. To configure Fuel Counter parameters use fuel consumption norms which are presented in the technical documentation of the vehicle. By default speeds for these fuel consumption norms are: City – 30 km/h, Average - 60 km/h, Highway - 90 km/h. These values can be changed.
  2. When speed is higher than the highway fuel consumption speed, x% of highway fuel consumption is added every extra y km/h, by default FMM001 adds 20% every 50 km/h of extra speed. For example, the fuel consumption is (1.2 * (Highway Fuel Consumption)) at 140 km/h and (1.4 * (Highway Fuel Consumption)) at 190 km/h.
  3. Correction coefficient is used to correct every value of fuel consumption which is sent to the server through an expression of ((Used Fuel) * Correction coefficient). By default it is 1, with minimum and maximum values of accordingly 0.01 and 2. For example, when correction coefficient is 1 and FMM001 calculates that the amount of used fuel over 35 m distance is 20 ml, the value of 20 ml will be sent to the server, and if correction coefficient is 1.2, the value of 20 * 1.2 = 24 ml will be sent to the server.
  4. Fuel Consumption on Idling is used to calculate fuel consumption when the ignition is on, but the vehicle is stationary. The consumption value is 1 l/h by default, with a minimum and maximum of accordingly 0 and 5 l/h. This parameter is less than 1.0 l/h for almost all diesel cars and is equal to about 1.5 – 2.0 l/h for gasoline cars.
