How to set ignition detection for TT2 object
How to set ignition detection for TT2 object
Updated over 6 months ago

Description:

Ignition detection configuration is quite critical because driving history and Trip reports are based on it.

Ideally ignition detection in LCM object settings should match with ignition detection in device configuration.

Common ignition detection sources:

  • Ignition(DIN4): This cable is usually connected to the ignition mechanism during installation. If connected properly It's output is 0 when ignition is off and 1 when ignition is on. Other DINs can also be used for this purpose. Binary output.

  • Power Supply Voltage: Power Supply Voltage usually surges when ignition is on in a vehicle, this means it can be used as an ignition source in some cases. However, one must know beforehand what is the voltage without ignition and with ignition to properly set it.

  • Speed: When a car is moving it usually indicates its ignition is on. However, using Speed as an ignition source will mean not detecting idling occurrences, as any stop, even if ignition remains off, will be regarded as ignition off by the system.

  • Movement sensor: Uses the internal accelerometers of the tracker to detect movement, which can be taken as an ignition source. As with Speed, idling occurrences will not be detected by this method. Binary output.

  • Custom Ignition: Allows you to combine with either AND or OR logic the conditions described above. Binary output.

Required information:

IMEI or other identifier

Physical connections of the device to the vehicle

Necessary to know if DIN can be used as ignition source, etc.

Steps:

Go straight to step 4 if you intend to use Speed as Ignition detection Input.

1- Open the device configuration.

2- Set the source of ignition detection "Engine" in the device configuration file (example shows Ignition(DIN4)).

3- Make sure the same source parameter is also enabled as a parameter IO Events with Event on Change and Priority High.

Alternatively, if historical data is available for this object, you can check which parameter best reflects the ignition state of the vehicle (usually by comparing it its relation to Speed, although if none suits Speed itself can be taken as an Ignition detection source).

4- Login to LCM.

5- Go to Objects and search for the object.

6- Go to View/Edit.

7- Go to Ignition detection section and select the same ignition source as in the configuration.

For binary Inputs like DIN, Custom ignition or Movement sensor use Condition > and value 0.

If needed you can Recalculate ignition to make TT2 recalculate trips in the past based on the newly set Ignition detection source.

8- Save.
