The emergency services call device establishes a minimum data set (MDS), which contains information about the
coordinates and time of the road accident, the VIN number of the vehicle and other information necessary for emergency
response operation.
Fig. 3.6 User interface unit:
1 - speaker; 2 - button for additional functions; 3 - "SOS" emergency call button; 4 - microphone
If during the dialing, you repeatedly press the "SOS" button and hold it for at least two seconds while the"SOS"
button backlight is flashing red, the emergency call will be cancelled (the red "SOS" button backlight will be turned off).
When transmitting MDS and during voice communication with the operator, the "SOS" button backlight lights up
continuously in red.
At the end of an emergency call (EC), the device must remain registered with the GSM/UMTS network and
automatically answer incoming calls for 60 minutes. When the connection is disconnected in the emergency call mode,
the emergency services call device must re-establish the connection with the emergency response service.
Emergency Services Call Device switches into standby mode when the voice communications are over.
Auto call mode
The emergency response service is automatically called when the vehicle rolls over. The algorithm of the emergency
services call device at automatic emergency response service is similar to the call mode of manual emergency response
service as described above, except there is no possibility to cancel the emergency call.
Automatic call can be completed only by emergency response service after confirmation by the vehicle driver that
there is no road accident or other emergency.
Standby Mode
In the "Standby" mode, the emergency services call device performs the following functions:
- reception of radio signals from global navigation satellite system (GNSS);
- calculation of navigational parameters;
- preparation of the MDS data package to ensure that it can be transmitted when an emergency call command is
received;
- preparation of a package of accompanying navigation data;
- monitoring the control actions of the interface module by using the "SOS" button;
- providing a response to the user's control actions;
- performing the self-diagnostic procedure;
- error detection;
- implementation of filtering procedures and control of indication signals;
- providing indication of system status and operation modes by means of wired connections of emergency services
call device and user interface unit.
“Sleep” mode
The emergency services call device goes from "Standby" mode to the "Sleep" mode when the ignition is turned off.
The emergency services call device stays in the "Sleep" mode for 72 hours. After the specified time has elapsed, the
emergency services call device goes to the "Off" mode.
In the "Sleep" mode, the emergency services call device responds to pressing the "SOS" key, turning on the ignition,
as well as disconnecting the battery pack.
The emergency services call device operates in the low power mode in the "Sleep" mode.
The emergency services call device also goes into sleep mode when the standard battery is disconnected. In this
event, the emergency services call device is powered from the built-in backup battery. In this event, the emergency
services call device stays in sleep mode for two hours, then it switches to "Off" mode to protect the backup battery from
over-discharging.
“Off” Mode
The emergency services call device stays in this mode if there is no emergency call, if the ignition is off and at least
