Odosync on the Ehubo

About Odosync

Odosync (or 'Odometer Sync' or 'odometer synchronisation') is an on-screen prompt for the Driver to manually input the vehicle's odometer reading on the Ehubo.

  • Odosync is recommended to maintain accurate virtual odometer reading on MyEROAD by calibrating the Ehubo distance reading with the vehicle's odometer. 
  • For RUC vehicles in NZ, Odosync must be completed 3 times over the first 2000km of driving in order to enable AutoRUC (automatic purchase to renew RUC license)
    • Default setting for calibration prompts: If and when the Odosync feature is toggled ON, Odosync prompts will show up at the ignition ON event after 500 km, 1000 km, and 2000 km distance marks.
    • Additional Odosync prompts can be configured by EROAD on behalf of the Customer org upon request (either by distance driven or elapsed time).

Virtual Odometer

The virtual odometer on MyEROAD is a digital 'counter', which is a combination of the vehicle odometer and the Ehubo distance reading. It increments automatically with the GPS-based Ehubo reading. The virtual odometer begins operating at the first Odosync event after a vehicle is provisioned with an Ehubo. Subsequent Odosync events further calibrate the virtual odometer based on the vehicle odo reading input by the Driver.

For fleet managers, administrators, tax users and other MyEROAD users, the virtual odo is a more practical indicator of vehicle odometer than the Ehubo reading.


Significant Odometer Jump (Odojump)

By using Ehubo as the primary source for distance reading, the virtual odometer expects the vehicle odometer to be within a tolerated range. If the Driver enters a vehicle odo reading that's out by more than 1000 km of this range, Odosync cannot be completed on the Ehubo screen. Instead, the Driver is advised to contact their supervisor to perform Odosync via MyEROAD. This reduces the impact of human error on the virtual odometer.

Odojump restriction will not apply for the first ever Odosync after an Ehubo is provisioned for a vehicle.

Likely reasons for odometer being outside the acceptable range:

  • Incorrect input by Driver, inadvertent or otherwise
  • Changing the tyre size or other vehicle modifications
  • Vehicle towed or transported (e.g. 'piggyback' on a trailer or on a ferry), where the Ehubo keeps accruing distance due to GPS movement

Does Odosync affect RUC for my Heavy vehicle?

Odosync has no impact on RUC for vehicles over 3.5 tonnes. Heavies are legally required to use approved electronic distance recorders like the Ehubo to track distance travelled, and hence RUC licenses too.

Does Odosync affect RUC for my Light vehicle?

For vehicles under 3.5 tonnes, RUC is based on the vehicle odometer. The virtual odometer is a reflection of the vehicle odometer on MyEROAD. Automatic RUC license renewal (AutoRUC) relies on the virtual odometer, and is impacted by Odosync. For this reason, the Odojump protection limits the impact on the virtual odometer and RUC.

What happens when I replace the Ehubo in my vehicle, or install it in a different vehicle?

Provisioning an Ehubo to a vehicle is the equivalent of a fresh, new install. In NZ, this also requires a RUCHO process to be completed for RUC-eligible vehicles.

The calibration Odosync prompts shall appear after 500km, 1000km and 2000km of driving from the time of provisioning/installation.

How do I enable/disable Odosync?

  1. Administration > Vehicles/Assets
  2. Select a vehicle. The vehicle's drawer will open
  3. Click Manage Features
  4. Toggle the 'Odosync prompt' ON/OFF

Every time this feature is set to ON, the calibration process begins again with Odosync prompts at 500 km, 1000 km and 2000 km of driving.

How can I set additional Odosync prompts for my vehicles?

Request EROAD to configure additional Odosync prompts for your vehicle. The frequency can be based on distance driven (e.g. every 2000 km) or by elapsed time (e.g. every 6 weeks).

Why is the odojump restriction ignored for the first Odosync?

When an Ehubo is provisioned for a vehicle, the virtual odometer is NULL – there is no prior Odosync. Therefore, Odojump cannot use the virtual odometer as a reference to protect against large offsets in the manual input. 

Does Odosync impact service scheduling?

Vehicle maintenance and service schedule can be configured by Ehubo reading (default) or the virtual odometer. Performing an Odosync will automatically configure it to use virtual odometer, without warning/notifying the Customer.

Can I use Odosync on a Heavy Vehicle?

Yes. Toggle the Odosync feature to ON (Administration > Vehicles/Assets > Manage Features). MyEROAD users can also manually trigger an Odosync prompt on a specific Ehubo. This will be a one-time prompt, unlike the 500 km/1000 km/2000 km calibration cycle. 

Note: Odosync will automatically configure the service schedule to use virtual odometer instead of Ehubo reading.
