Template:FMM640 Green Driving
Green Driving[edit source]
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 Green Driving functionality are given in a table below.
|Output Control||Enable/Disable Green driving functionality and Activate/Deactivate DOUT.|
|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.|

Note: To use “Accelerometer Algorithm A1” option user need to install device as in Figure 1.
FMB640 Device accelerometer position. (With positive Z axis pointing to Ground and antennas face forward in the vehicle). Before operation with the vehicle on level ground user must send “setacc” SMS.
Auto calibration[edit source]
The auto-calibration process is the following:
- The vehicle is stopped.
- There is a straight road ahead.
- Send SMS "auto_calibrate:set" to the FMB device.
- Accelerate to >30 km/h for 5 sec.
- FMB 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 FMB device: "auto_calibrate:get".
