Introduction to Smart Ignition Detection functionality
Smart Ignition detection is a functionality which detects ignition by sudden external voltage jumps instead of manually predefined High and Low voltage thresholds. This feature is especially beneficial to clients who want to monitor the ignition status of a vehicle based on the voltage of the battery, irregardless of the battery's health.
Smart Ignition Detection functionality logic
“Smart Ignition Detection”– detects ignition “on” and “off” automatically by monitoring last “Smart Ignition Duration” seconds of external voltage and comparing it to current external voltage value. If current external voltage value is higher by “Smart Ignition Delta” than external voltage “Smart Ignition Duration” seconds ago, Ignition “on” event is detected. If current external voltage value is lower by “Smart Ignition Delta” than “Smart Ignition Duration” seconds ago Ignition “off” event is detected.
Smart Ignition Detection configuration
New configurable parameters were added under “Ignition Settings” (Figure 2):
• Smart Ignition Enable/Disable – To enable functionality. Parameter is able to be configured if “Ignition Source” has “Power Voltage” configured.
• Smart Ignition Delta (mV) – How much external voltage must change to detect ignition ON or OFF event.
• Smart Ignition Duration (s) – Time interval used for comparing current external voltage against historical external voltage configured seconds ago.
In case the vehicle has a variable voltage alternator, also known as a smart alternator, an alternative configuration is advised -- taking into account movement detection by accelerometer, in order to monitor the ignition status of the vehicle.
Parameter list
| Parameter ID | Name | Value range | Description | ||
|---|---|---|---|---|---|
| Min | Max | Default | |||
| 66201 | Smart Ignition | 0 | 1 | 1 | 0 - Disabled; 1 - Enabled |
| 66202 | Smart Ignition Delta, mV | 100 | 2000 | 600 | How much external voltage must change, in miliVolts to detect ignition ON or OFF event. |
| 66203 | Smart Ignition Duration, s | 2 | 20 | 3 | Time interval, in seconds, used for comparing current external voltage against historical external voltage configured seconds ago. |
Firmware and hardware compatibility
Smart ignition detection functionality is available for FMT100/FMX880 devices on the firmware 03.29.00.rev.980. You can download the firmware and configurator here.
