Speed Alerts

The Outback Navigation Information System (ONIS) includes an integrated Speed Alert system to assist the driver in managing vehicle speed.

When using the OziExplorer navigation app, the Speed Alert system:

• incorporates Geofence, Adaptive and User Speed Alerts

• displays audio & visual Speed Alert or Speed Alarm messages when the vehicle speed is above the Speed Alert limit

• can be configured (in the setup mode) as single or continuous audible alert messages as voice or beep, when the vehicle speed is above the Speed Alert limit

• can be configured (in the setup mode) to have a default maximum value of 100 or 110 km/h

• can be configured with a base value between 10 km/h and the maximum value, in increments of 10 km/h

• has speed tolerance values ranging from 0 km/h to +3 km/h, and the combination of the base and tolerance values is summated to provide the Speed Alert value displayed on the screens and used as the threshold for driver warnings. e.g. a manual setting of 60 km/h with a tolerance of +1 km/h will set the Speed Alert to 61 km/h

•  the ONIS owner can disable the tolerance setting option (refer to Owner Options). 

The round Speed Alert symbol in the left menu bar will display the km/h current setting value and if selected, will display the Speed Alert setting menu.

Selecting the digital speed display will set the Speed Alert to the the current vehicle speed. 

e.g if the vehicle is traveling at 33 km/h, the Speed Alert will be se to 40km/h.

Long pressing on the digital speed display will set the Speed Alert to the maximum value (100 or 110 km/h depending on the configuration) and toggle the Adaptive mode on / off (if purchased).

Left side menu Speed Alert symbol background colours:

• white: User mode (manual)
• green: Adaptive mode
• white with an inner yellow ring: Geofence Speed Alert has been found, but the User mode setting is lower
• white with an outer yellow square border: The Geofence Speed Alert system is enabled but the vehicle is not in a an active Geofence area
• yellow: Geofence Speed Alert found, active and overriding the User mode value.

The ONIS tools are easy to understand and use, however Geofence Speed Alert management in general can be complex and we recommend some training in this area to ensure a robust implementation.

The Geofence Speed Alert mode will alert the driver when the speed exceeds the predefined Geofence data record (N/A in Personal Mode).

The Geofence Speed Alert mode :

• displays a yellow background when the Geofence mode is enabled & active

•  displays a white background, yellow outer square border and a yellow inner circle when the Geofence mode is enabled, but the driver manually set speed alert is set lower

•  displays a white background with a yellow outer yellow square border when the Geofence mode is enabled and the vehicle is not in a Geofence active area

• can be set as "enabled" or "disabled" as the default, when the ONIS starts up

•  can be disabled by the driver from the Speed Alert setting menu (the owner can override this function, if required) 

• if the Geofence mode is active, then this setting will override both the User and Adaptive modes

• can only become active if the vehicle speed is not greater than 25 km/h above the Geofence setting. This reduces the Speed Alert alert messages when traveling on minor roads with a low speed limit adjacent to main roads, both of which are in the same Geofence boundary.

The Geofence Speed Alert system features either a Speed Alert message or a Speed Alarm message if the vehicle exceeds the Geofence ONIS speed limit.

• the Speed Alert message advises the driver that the vehicle is exceeding the ONIS speed limit and allows the driver to view the map and /or set another limit (dependent on owner options). The audible warning can be configured by the driver as "once" or "continuous", and "beep" or "voice".

• the Speed Alarm message is a Speed Alert that has been configured as "critical". A Speed Alarm will display a full screen message blocking all ONIS functions whilst still displaying the current vehicle speed and the current speed limit. An audible message will also be broadcast at maximum volume and the message will repeat every 2 seconds (approx.) until the vehicle speed is reduced or the vehicle leaves the Geofence critical zone.

User Geofence data records can be configured by using the inbuilt capture tool or using a PC connected to the ONIS, and the import/export tool. The Geofence records can be set as Alert or Alarm)

System Geofence data records are secured and only configurable by ONIS administrator (with information provided by the customer) and installed during the build process.

System Geofence data records will take precedence over User mode entries if both are found for the same current Geofence location.

We recommend only using the Geofence Speed Alarm setting for areas of critical impact to persons or equipment which can be determined by using the risk assessment process.

eg, Geofence speed limit settings in a car park frequented by pedestrians may warrant the Speed Alarm setting in preference to the Speed Alert setting.

eg, Geofence speed limit settings in a process area where vehicle impact would cause catastrophic impacts on production, may warrant the Speed Alarm setting in preference to the Speed Alert setting.

We recommend only using configuring the System Geofence data records if the data WILL NOT change for the life of the ONIS. 

The most accurate speed alerts are location based (eg. Geofence), however for locations that do not have a Geofence record, the ONIS Adaptive mode can be another option.

The ONIS Adaptive mode automatically sets the Speed Alert to a predefined setting when the vehicle speed is between +/-3 km/h of the predefined setting for 5 seconds (approx.) and the vehicle is within the pre-set acceleration limits.

Predefined speed settings are 10, 20, 30 40, 50, 60, 70, 80, 90, 100 or 110 km/h

The algorithm used to set the Adaptive mode also uses vehicle acceleration and deceleration, and will only set the new Speed Alert value when these are also within the predefined limits (+/- 2 m/s2).

e.g. 

If the current vehicle Speed Alert is set to 60 km/h, and the driver steadily and continuously increases the vehicle speed to 110 km/h, the Speed Alert setting will automatically and ONLY change to 110 km/h after 5 seconds at 110 km/h.

The Adaptive mode:

•  will show a large green background symbol displaying the new new Speed Alert 

• does NOT suit drivers who are serial speed offenders or drivers that do NOT sit at the designated speed limit

•  is not designed for intentional over speed

•  only assists in unintended speed deviations above the setting

• can be enabled or disabled from the Speed Alert menu when the navigation app is running

• speed tolerance settings are disabled when the Adaptive mode is enabled

• has a manual "SET" button if the Speed Alert message is active, allowing the driver to manually set to the current vehicle speed. 

• will display a green background.

A good use of the Adaptive mode could be when a driver slows down to 40 km/h for construction road work. Once the vehicle is at 40 km/h (+/-3 km/h, not accelerating or decelerating) for 5 seconds, the Speed Alert will set to 40. If the driver then unintentionally creeps (less than 47 km/h) over the Speed Alert setting, the driver will receive an Alert waning.

We recommend limiting the use of the Adaptive mode to regional and remote driving as city driving with the continuous stop / start driving, will may to many unwanted alerts.

The ONIS User mode is the simplest mode and allows the user to set Speed Alerts that will remain set until another value is set.

Predefined speed settings are 10, 20, 30 40, 50, 60, 70, 80, 90, 100 or 110 km/h

The User mode:

• can be enabled or disabled from the Speed Alert menu when the navigation app is running

• will display a white background.
